Description

Technical Field

[0001] This invention belongs to the field of compressor technology, and more specifically, relates to an energy-saving compressor with a flow regulation structure and a flow regulation method. Background Technology

[0002] In the fields of industrial production and energy supply, compressors, as gas compression and transportation equipment, affect the efficiency and cost of production systems due to their energy consumption level and flow adaptability.

[0003] With the deepening of the concept of energy conservation and environmental protection and the increasing requirements of industrial production for gas supply, the core demands of the current market for compressors are gradually focusing on low energy consumption operation and wide-range flow regulation. However, in practical applications, existing compressors generally adopt a flow control method that opens the pressure regulating valve at a fixed time. During the piston compression stage, regardless of whether the actual pressure in the compression chamber meets the standard, the pressure regulating valve will open at a preset time, discharging part of the compressed gas into the storage tank. The work done by the piston on this discharging gas becomes completely useless. Furthermore, the control logic of opening at a fixed time cannot adapt to the dynamic flow demand of the gas-using equipment. When the demand flow changes, the timing of the pressure regulating valve is difficult to adjust synchronously, which can easily lead to excessive or insufficient gas supply, resulting in energy waste. Secondly, the high-pressure gas in the storage tank is prone to backflow due to poor sealing of the pressure regulating valve. This backflow, combined with the new gas drawn in when the piston descends, creates a counterflow in the compression chamber, resulting in airflow turbulence and pressure fluctuations, which reduces compression efficiency and gas delivery stability. Summary of the Invention

[0013] A flow regulation method for an energy-saving compressor with a flow regulation structure, applied to the aforementioned energy-saving compressor with a flow regulation structure, is characterized by comprising the following steps: S1: The piston moves down to the bottom dead center, causing the pressure in the compression chamber to drop. The moving block moves to the intake position, and air flows into the compression chamber through the external intake pipe, the intake check valve, and the airflow passage. S2: The piston moves upward, reducing the volume of the compression chamber to compress the air. The movable block moves to the exhaust position, pushing the contact block and the linkage block to squeeze the first pressure sensor to obtain real-time air pressure data. S3: Obtain the preset exhaust pressure threshold, compare the real-time air pressure data with the exhaust pressure threshold, open the exhaust solenoid valve to exhaust air based on the comparison result and obtain exhaust flow data; S4: Obtain preset flow demand data, match flow demand based on exhaust flow data and flow demand data, adjust piston stroke based on matching result, and cycle from S1 to S4 based on adjusted piston stroke.

[0014] As a further aspect of the present invention, the step of comparing real-time air pressure data with an exhaust pressure threshold, opening the exhaust solenoid valve to exhaust air based on the comparison result, and obtaining exhaust flow data includes: Compare the real-time air pressure data with the preset exhaust pressure threshold; Specifically, when the real-time air pressure data is greater than or equal to the preset exhaust pressure threshold, the comparison result of "exhaust conditions met" is output; when the real-time air pressure data is less than the preset exhaust pressure threshold, the comparison result of "exhaust conditions not met" is output. When the comparison result is "exhaust conditions met", the exhaust solenoid valve is opened, and exhaust flow data is collected through the air flow valve at the same time. When the comparison result is "exhaust conditions not met", the exhaust solenoid valve remains closed, and the compression chamber continues to compress as the piston rises until the real-time air pressure data is greater than or equal to the preset exhaust pressure threshold. The process of matching flow demand based on exhaust flow data and flow demand data, and adjusting piston stroke based on the matching result, includes: Traffic demand data is represented as an allowable deviation range, and the matching results include match, traffic too high, and traffic too low. Matching: Exhaust flow rate data within the allowable deviation range indicates that the current exhaust flow rate can meet the gas demand and no adjustment is required; Excessive flow rate: Exhaust flow rate data > permissible deviation range indicates that the current exhaust flow rate exceeds the demand, which will cause energy waste and the flow rate needs to be reduced; Low flow rate: Exhaust flow rate data < allowable deviation range indicates that the current exhaust flow rate cannot meet the demand and the flow rate needs to be increased; When the matching result indicates that the flow rate is too high, shorten the piston stroke; When the matching result indicates that the flow rate is too low, extend the piston stroke.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, by switching the intake and exhaust positions of the movable block in the ventilation structure, combined with real-time air pressure data obtained from four sets of first pressure sensors, the exhaust solenoid valve is opened only after the air pressure reaches the target level, avoiding ineffective energy consumption caused by the piston doing work on excess gas. This also eliminates the need for a pressure regulating valve, a temporary storage tank, and related connecting pipes, solving the energy loss caused by the traditional compressor opening the pressure regulating valve at fixed intervals to discharge excess gas into the temporary storage tank, thus improving the energy efficiency of the compressor operation. Second, the connection between intake and exhaust is achieved by switching the position of the movable block. During intake, the connecting pipe only connects to the intake one-way valve; during exhaust, the connecting pipe only connects to the exhaust solenoid valve, avoiding interference between the intake and exhaust processes. This eliminates the airflow turbulence problem caused by high-pressure gas backflow in the temporary storage tank in traditional structures, and also... Real-time air pressure data collected by the first pressure sensor provides a reliable basis for the opening and closing of the exhaust solenoid valve, ensuring stable pressure in the compression chamber, preventing piston and cylinder wall wear caused by airflow collision, and improving the stability of compressor operation. Furthermore, the stroke adjustment structure adjusts the piston stroke by adjusting the motor-driven gear to rotate along the internal gear ring, which in turn moves the eccentric shaft linearly. Combined with the air flow valve on one side of the exhaust solenoid valve to monitor the exhaust flow, it can dynamically adjust the gas volume of a single compression according to actual flow requirements. Simultaneously, the locking slider can fix the gear after stroke adjustment, preventing stroke deviation during compressor operation, ensuring the accuracy and stability of flow regulation, improving the compressor's flow adaptability, and flexibly meeting the dynamic needs of different gas-using equipment.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0019] Example

[0020] As attached Figures 1 to 13 As shown: This invention provides an energy-saving compressor with a flow regulation structure, comprising: A compression chamber 102 is provided at the bottom of the air-side diaphragm head 101. An airflow channel 103 provided at the top of the air-side diaphragm head 101 communicates with the compression chamber 102 to facilitate the inflow and outflow of air before and after compression, ensuring a directional transmission path for the gas between the compression chamber 102 and the external pipeline. An oil-side diaphragm head 104 is provided at the bottom of the air-side diaphragm head 101. The bottom end of the oil-side diaphragm head 104 is connected to an oil cylinder 106 via a piston cylinder 105. A piston 107 is slidably disposed within the piston cylinder 105. The piston 107 reciprocates and drives the oil-side diaphragm head 104 and the air-side diaphragm head 101 to move, ultimately achieving the volume contraction and expansion of the compression chamber 102, completing the air intake and compression process. A ventilation structure is installed in the airflow channel 103. The ventilation structure, used for switching between intake and exhaust and acquiring air pressure data within the compression chamber 102, includes a movable block 201 located at either the intake or exhaust position, and four sets of first pressure sensors 202 for acquiring real-time air pressure data. The movable block 201, switching between the intake and exhaust positions, allows for alternating flow of the intake and exhaust passages. A sliding frame 203 is fixedly installed within the airflow channel 103, providing guidance and limiting for the sliding of the movable block 201, ensuring it can move to the preset intake or exhaust position. The four sets of first pressure sensors 202 arranged around the sliding frame 203 acquire real-time air pressure data within the compression chamber 102 during the exhaust phase, providing information for the timing of exhaust. The judgment provides a basis for judgment; when the piston 107 slides downward to expand the volume of the compression chamber 102, the movable block 201 moves to the intake position with the movement of the air-side diaphragm head 101. At this time, the intake passage in the airflow channel 103 is opened, and external air enters the compression chamber 102. When the piston 107 slides upward to compress the air, the movable block 201 moves to the exhaust position. At this time, the four sets of first pressure sensors 202 begin to collect the air pressure data in the compression chamber 102 and provide real-time feedback on the compression progress; the eccentric wheel 108 in the cylinder body 106 is connected to the bottom end of the piston 107 through a stroke adjustment structure. The stroke adjustment structure changes the transmission distance between the eccentric wheel 108 and the piston 107 to realize the stroke of the piston 107 in the piston cylinder body 105. The stroke adjustment structure increases or decreases the stroke of piston 107, thereby adjusting the gas volume of a single compression to adapt to different flow requirements. The stroke adjustment structure increases the stroke of piston 107, causing the volume change of compression chamber 102 to increase with each sliding motion of piston 107, thus increasing the amount of gas compressed per stroke. When the gas flow requirement decreases, the stroke adjustment structure shortens the stroke of piston 107, reducing the amount of gas compressed per stroke. The lubrication and cooling structure is installed inside the cylinder body 106. By delivering cooled lubricating oil to the contact area between piston 107 and piston cylinder body 105, it lubricates and cools piston 107 and piston cylinder body 105, reducing the frictional resistance generated by their relative sliding and removing the heat generated by friction to prevent damage to components due to high temperature.

[0021] Please see as follows Figure 3 , Figure 4 and Figure 5 As shown, the ventilation structure also includes a ventilation pipe 205, which is located at the top of the airflow channel 103. A connecting pipe 206 is located at the top of the movable block 201. The top of the connecting pipe 206 slides through the ventilation pipe 205 and can adjust the position of the connecting pipe 206 in the ventilation pipe 205 synchronously with the position change of the movable block 201, thereby realizing the switching between the air intake passage and the exhaust passage. An exhaust solenoid valve 207 is installed at the top of the vent pipe 205. The top of the exhaust solenoid valve 207 is connected to an external exhaust pipe. When compressed gas needs to be discharged, the exhaust solenoid valve 207 opens, allowing the compressed gas to pass through the vent pipe 205 and the exhaust solenoid valve 207 into the external exhaust pipe, and finally be delivered to the gas-using equipment. When no discharge is needed, it remains closed. An air flow valve 208 is installed on one side of the exhaust solenoid valve 207 to acquire exhaust flow data. The air flow valve 208 can monitor the gas flow through the exhaust solenoid valve 207. A pin 209 is installed at the top of the vent pipe 205. A sealing plate 210 is installed at the bottom of the exhaust solenoid valve 207. A spring 211 is installed inside the exhaust solenoid valve 207 corresponding to the sealing plate 210. The bottom of the spring 211 contacts the sealing plate 210, and the spring 211 can provide a reset force for the sealing plate 210, so that the sealing plate 210 can close the bottom of the exhaust solenoid valve 207. An inlet check valve 212 is installed on one side of the vent pipe 205. The top of the inlet check valve 212 is connected to an external inlet pipe. The inlet check valve 212 is used to ensure that external air can only enter the equipment in one direction, preventing backflow of the incoming air or compressed gas and ensuring the unidirectional flow of gas. An inlet hole 226 is opened on one side of the connecting pipe 206 corresponding to the inlet check valve 212. The inlet hole 226 serves as a connection channel between the connecting pipe 206 and the inlet check valve 212, and is used to connect the two during the air intake stage, ensuring that external air can smoothly enter the connecting pipe 206 and flow to the compression chamber 102.

[0022] In this embodiment, when the movable block 201 is in the air intake position, the top of the ejector pin 209 does not contact the sealing plate 210, and the spring 211 is in a naturally extended state. Under the force of the spring 211, the sealing plate 210 seals the bottom of the exhaust solenoid valve 207, so that the connecting pipe 206 is not connected to the exhaust solenoid valve 207, thus preventing gas from leaking from the exhaust passage during the air intake process. At the same time, the air intake hole 226 and the air intake check valve 212 are located on the same axis. The connecting pipe 206 is connected to the air intake check valve 212 through the air intake hole 226. Under the negative pressure formed by the compression chamber 102, the external air enters the connecting pipe 206 through the external air intake pipe, the air intake check valve 212, and the air intake hole 226 in sequence, and then flows into the compression chamber 102 through the airflow channel 103, completing the air intake process.

[0023] When the movable block 201 is in the exhaust position, the movable block 201 drives the connecting pipe 206 to move upward, so that the top of the ejector pin 209 contacts the sealing plate 210 and generates an upward thrust. This thrust overcomes the elastic force of the spring 211 and pushes the sealing plate 210 upward. At this time, the sealing plate 210 does not seal the bottom of the exhaust solenoid valve 207, and the connecting pipe 206 is connected to the exhaust solenoid valve 207, forming a complete exhaust passage. At the same time, the movement of the connecting pipe 206 causes the air inlet 226 and the air inlet check valve 212 to be out of sync, and the connecting pipe 206 is not connected to the air inlet check valve 212, cutting off the air inlet passage and preventing compressed gas from leaking from the air inlet side. The high-pressure gas in the compression chamber 102 enters the connecting pipe 206 through the airflow channel 103, and then enters the external exhaust pipe through the vent pipe 205 and the exhaust solenoid valve 207, completing the exhaust process.

[0024] Please see as follows Figure 5 , Figure 6 and Figure 7As shown, the sliding frame 203 has a mounting ring 213 at its top and a fixing block 214 at its top. The mounting ring 213 is engaged between the air-side membrane head 101 and the fixing block 214. The bottom of the sliding frame 203 has a through sliding hole 215. The vent pipe 205 slides through the sliding hole 215, which provides a sliding guide for the vent pipe 205, ensuring that the vent pipe 205 can move smoothly in a preset direction when it moves with the movable block 201, avoiding deviation and jamming. The sliding frame 203 has four sets of sliding seats 216 around its periphery. Each of the four sets of sliding seats 216 has a sliding groove 217. An abutment block 218 is slidably connected in the sliding groove 217. The sliding groove 217 provides a limiting guide for the sliding of the abutment block 218, ensuring that the abutment block 218 can only move along the extension direction of the sliding groove 217. Four sets of guide grooves 219 are provided at one end of the sliding seat 216. The linkage block 220 is slidably connected to the four sets of guide grooves 219 through four sets of guide sliders 221. The cooperation between the guide grooves 219 and the guide sliders 221 provides guidance for the movement of the linkage block 220. The first pressure sensor 202 is installed on one side of the linkage block 220 and contacts the inner wall of the airflow channel 103. A guide hole is provided on the other side of the linkage block 220, and a guide post 223 is provided on one side of the abutment block 218. The guide post 223 slides through the guide hole. The cooperation between the guide post 223 and the guide hole can make the thrust of the abutment block 218 smoothly transmitted to the linkage block 220, ensuring that the first pressure sensor 202 is subjected to uniform force and improving the stability of air pressure data acquisition. Four sets of first rotating seats 224 are provided on the periphery of the movable block 201 corresponding to four sets of sliding seats 216. Each of the four sets of first rotating seats 224 is rotatably connected to one end of the linkage rod 225 through a first rotating shaft. The other end of the linkage rod 225 is rotatably connected to the abutment block 218 through a second rotating shaft. The first rotating seat 224 serves as the connecting component between the movable block 201 and the linkage rod 225. It works with the two sets of rotating shafts to realize the rotation of the linkage rod 225, so that the linear movement of the movable block 201 can be converted into the linear sliding of the abutment block 218.

[0025] In this embodiment, when the movable block 201 moves upward toward the exhaust position, the movable block 201 drives the four sets of first rotating seats 224 to move upward synchronously. The first rotating seat 224 drives one end of the linkage rod 225 to swing upward through the first rotating shaft, and the other end of the linkage rod 225 pushes the abutment block 218 to move along the sliding groove 217 toward the linkage block 220 through the second rotating shaft until one side of the abutment block 218 contacts the linkage block 220 and squeezes the first pressure sensor 202. Under the squeezing action, the first pressure sensor 202 senses the air pressure in the airflow channel 103, and then obtains the real-time air pressure data in the compression chamber 102 through the first pressure sensor 202, providing a basis for judging the exhaust timing. When the movable block 201 moves downward toward the air intake position, the movable block 201 drives the first rotating seat 224 to move downward synchronously. The first rotating seat 224 pulls one end of the linkage rod 225 downward through the first rotating shaft, and the other end of the linkage rod 225 pulls the abutment block 218 along the sliding groove 217 away from the linkage block 220 through the second rotating shaft until the abutment block 218 moves to one end of the sliding groove 217. At this time, the abutment block 218 separates from the linkage block 220, the first pressure sensor 202 is no longer squeezed, and stops collecting air pressure data.

[0026] Please see as follows Figure 8 , Figure 9 and Figure 10As shown, the stroke adjustment structure includes an adjustment motor 301, which serves as the power source for stroke adjustment, providing power to drive the gear 305 to move and thus increase or decrease the stroke of the piston 107. An eccentric wheel 108 has a mounting groove 302 on one side, providing mounting space for components such as the internal gear ring 303 and the adjustment motor 301. The internal gear ring 303 is fixedly installed within the mounting groove 302, providing trajectory support for the movement of the gear 305. The adjustment motor 301 is positioned at the center of one side of the mounting groove 302, and a second rotating seat 304 is mounted on the main shaft of the adjustment motor 301. A rotating shaft is located on one side of the second rotating seat 304, and a gear 305 is mounted on the rotating shaft. The gear 305 meshes with the internal gear ring 303, and through this meshing, the rotational motion of the adjustment motor 301 is converted into the circumferential movement of the gear 305 along the internal gear ring 303. An eccentric shaft 306 is provided on one side of the gear 305. The eccentric shaft 306 is rotatably connected to the bottom end of the piston connecting rod 307, and the top end of the piston connecting rod 307 is connected to the bottom of the piston 107. When the eccentric shaft 306 moves with the gear 305, it changes its position relative to the eccentric wheel 108, thereby causing the piston 107 to change its stroke within the piston cylinder 105 via the piston connecting rod 307. The stroke adjustment structure also includes a locking slider 308, which is used to fix the gear 305 after the stroke adjustment is completed, preventing the gear 305 from shifting during equipment operation and ensuring the stability of the piston 107's stroke. A locking seat 309 is also provided on one side of the second rotating seat 304, and a locking groove 310 is provided on one side of the locking seat 309. The locking slider 308 is slidably disposed in the locking groove 310, which provides guidance for the movement of the locking slider 308, ensuring that the locking slider 308 can move in a preset direction and engage or disengage from the gear 305. One end of the locking slider 308 is engaged between two teeth of the gear 305, mechanically restricting the rotation of the gear 305. Two sets of locking tooth grooves 312 are symmetrically arranged on both sides of the locking slider 308. Two sets of locking gears 313 are arranged on one side of the locking seat 309. The two sets of locking gears 313 mesh with the two sets of locking tooth grooves 312 respectively. Through the meshing transmission between the locking gears 313 and the locking tooth grooves 312, the rotational power of the locking motor 314 is converted into the linear movement of the locking slider 308. The locking motor 314 is arranged on the other side of the locking seat 309. The main shaft of the locking motor 314 is connected to one set of locking gears 313. The locking motor 314 provides power for the movement of the locking slider 308, realizing the unlocking and locking of the gear 305.

[0027] In this embodiment, before the stroke of the adjusting piston 107, the gear 305 needs to be unlocked. At this time, the locking motor 314 is started, and the locking motor 314 drives a set of locking gears 313 connected to it to rotate. This set of locking gears 313 drives the locking slider 308 to move along the locking groove 310 by meshing with the corresponding locking tooth groove 312. At the same time, another set of locking gears 313 cooperates with the corresponding locking tooth groove 312 to ensure that the locking slider 308 moves smoothly until one end of the locking slider 308 is completely removed from between two teeth of the gear 305, releasing the restriction on the gear 305. At this time, the gear 305 can be driven to rotate by the adjusting motor 301. When the adjusting motor 301 is started, its main shaft drives the second rotating seat 304 to rotate. The second rotating seat 304 drives the rotating shaft and the gear 305 to rotate synchronously. Since the gear 305 meshes with the internal gear ring 303, the gear 305 rotates simultaneously. The gear 305 rotates along the tooth surface of the internal gear ring 303. When the gear 305 moves, it drives the eccentric shaft 306 on one side to move linearly relative to the eccentric wheel 108. The eccentric shaft 306 drives the piston 107 to change the moving distance of the piston 107 in the piston cylinder 105 through the piston connecting rod 307, thereby increasing or decreasing the stroke of the piston 107. After the stroke of the piston 107 is adjusted, the gear 305 needs to be locked to fix the stroke. At this time, the locking motor 314 rotates in the opposite direction, driving the locking gear 313 to rotate in the opposite direction. The locking gear 313, through meshing with the locking tooth groove 312, pushes the locking slider 308 to move again along the locking groove 310 until one end of the locking slider 308 is locked between the two teeth of the gear 305 again. The rotation of the gear 305 is restricted by mechanical locking, thus locking the gear 305 and ensuring that the piston 107 maintains a stable stroke after adjustment during subsequent operation.

[0028] Please see as follows Figure 11 , Figure 12 and Figure 13As shown, the lubrication and cooling structure includes an oil pump 401. The cylinder 106 contains a dual-purpose hydraulic transmission oil, which serves as a lubricant, coolant, and hydraulic transmission fluid, simultaneously meeting the equipment's lubrication, cooling, and hydraulic transmission requirements. A compression chamber 112 is located at the top of the oil-side diaphragm head 104. The oil pump 401 acts as the power source for oil delivery, drawing the dual-purpose hydraulic transmission oil from the cylinder 106 and delivering it to the lubrication and cooling section, while also replenishing the compression chamber 112 with hydraulic transmission oil. The oil pump 401 is located on one side of the cylinder 106, facilitating rapid extraction of the hydraulic transmission oil from the cylinder 106. The oil pump 401 has a first outlet and a second outlet. The first outlet delivers cooled and filtered oil to the contact area between the piston 107 and the piston cylinder 105. The second outlet on one side of the oil pump 401 is connected to the compression chamber 112 via a pipeline, and is used to replenish the compression chamber 112 with hydraulic oil. A rotary connecting seat 402 is rotatably mounted on one side of the eccentric shaft 306. A rotary connector 403 is connected to the first oil outlet end via a pipeline. The rotary connector 403 rotatably passes through the rotary connecting seat 402. The cooperation between the rotary connecting seat 402 and the rotary connector 403 enables rotational connectivity of the oil passage, ensuring that the oil passage remains unobstructed during the rotation of the eccentric shaft 306 and preventing pipeline entanglement or damage. A first oil passage 407 is provided inside the piston connecting rod 307. The circumference of the rotary connecting seat 402 is connected to the first oil passage 407 via a rigid oil supply pipe 404. The rigid oil supply pipe 404 is used to stably deliver oil from the rotary connecting seat 402 to the first oil passage 407. The piston connecting rod 307 is rotatably connected to the piston base 405 via a connecting shaft 406. A third oil passage 408 is provided inside the piston base 405. Two sets of annular oil channels 409 are provided around the connecting shaft 406, corresponding to the first oil passage 407 and the second oil passage 410. The two sets of annular oil channels 409 are connected through the second oil passage 410. The annular oil channels 409 ensure that the oil remains connected to the oil passages during the rotation of the connecting shaft 406, achieving stable oil transmission. One end of the first oil passage 407 is connected to one set of annular oil channels 409, and one end of the third oil passage 408 is connected to the other set of annular oil channels 409, forming a continuous oil delivery path. Two sets of slots are provided around the piston 107, each containing an oil ring. The outer side of the oil ring contacts the inner wall of the piston cylinder 105. The oil ring enhances the sealing between the piston 107 and the piston cylinder 105, while also assisting in lubrication and reducing friction between them. The piston 107 has multiple sets of angled oil outlets 412 at its bottom. The oil outlets 412 are used to evenly deliver oil to the contact area between the piston 107 and the piston cylinder 105, ensuring uniform lubrication and cooling. A connecting rod 413 is provided at the bottom of the piston 107. The top of the piston base 405 is connected to the bottom of the connecting rod 413 by screws, realizing a stable connection between the piston base 405 and the piston 107.A fourth oil passage 414 is provided inside the piston 107 and the connecting rod 413. The bottom end of the fourth oil passage 414 is connected to the third oil passage 408, and the top end of the fourth oil passage 414 is connected to multiple sets of oil outlets 412, which are used to guide the oil transported by the third oil passage 408 to the oil outlets 412. A connecting sleeve 109 is provided at the bottom end of the piston cylinder 105. The connecting sleeve 109 passes through the top of the cylinder body 106 to achieve a stable connection between the piston cylinder 105 and the cylinder body 106. Multiple sets of oil return grooves 416 are provided inside the connecting sleeve 109. The oil return grooves 416 are used to guide the oil discharged from the oil outlets 412 back to the cylinder body 106 to achieve oil recycling.

[0029] The lubrication and cooling structure also includes a cooler 417, which cools the extracted hydraulic transmission dual-purpose oil, reducing its temperature and improving cooling efficiency. Two sets of filter cages 418 are installed on one side of the cooler 417, both submerged in the hydraulic transmission dual-purpose oil. The filter cages 418 filter impurities in the oil, preventing them from entering the oil passages and causing blockages or accelerating component wear. The top of the cooler 417 is connected to the oil inlet of the oil pump 401, ensuring that the oil drawn by the pump 401 is first filtered and cooled.

[0030] In this embodiment, when the equipment requires lubrication and cooling during operation, the oil pump 401 is started. The oil pump 401 draws hydraulic transmission oil from the cylinder body 106 through the oil inlet. The oil first passes through two sets of filter cages 418 to remove impurities, and then enters the cooler 417 for cooling. The cooled and filtered oil is output through the first oil outlet of the oil pump 401 and transported to the rotary connector 403 via pipeline. The rotary connector 403 rotates within the rotary connector seat 402 to ensure unobstructed oil passage. The oil enters the rigid oil supply pipe 404 through the rotary connector seat 402, and is then transported by the rigid oil supply pipe 404 to the first oil passage 407 within the piston connecting rod 307. The oil flows along the first oil passage 407 to one set of annular oil channels 409 of the connecting shaft 406, and then flows into another set of annular oil channels 409 through the second oil passage 410. The oil enters the third oil passage 408 inside the piston base 405; the oil in the third oil passage 408 flows into the fourth oil passage 414 inside the connecting rod 413 and the piston 107, and is finally sprayed out through multiple sets of oblique oil outlets 412 at the bottom of the piston 107, evenly covering the contact area between the piston 107 and the piston cylinder 105, achieving lubrication and cooling; the excess oil after lubrication and cooling flows along the inner wall of the piston cylinder 105 to the return oil groove 416 inside the connecting sleeve 109, and flows back to the oil cylinder 106 through the return oil groove 416, completing the oil circulation; at the same time, the second oil outlet on one side of the oil pump 401 is connected to the compression oil chamber 112 through a pipeline, which can continuously replenish the hydraulic transmission dual-purpose oil to the compression oil chamber 112, maintain the pressure stability in the compression oil chamber 112, and ensure that the compression diaphragm 111 can obtain sufficient thrust to complete the compression action.

[0031] An oil distribution plate 110 is provided between the air-side diaphragm head 101 and the oil-side diaphragm head 104. A compression diaphragm 111 is provided between the oil distribution plate 110 and the air-side diaphragm head 101. A compression oil chamber 112 is provided at the top of the oil-side diaphragm head 104. The compression oil chamber 112 is used to store hydraulic transmission oil and transmit pressure, providing the power basis for the deformation of the compression diaphragm 111. A second pressure sensor 113 is provided on one side of the oil-side diaphragm head 104. The second pressure sensor 113 is used to monitor the amount of hydraulic oil in the compression oil chamber 112. When the hydraulic oil in the compression oil chamber 112 is low, it can be replenished through the second oil outlet on one side of the oil pump 401 via a pipeline. The bottom of the cylinder body 106 is provided with a device for installing this device. The base frame 114 is equipped with a drive motor 115 on its top. The main shaft of the drive motor 115 is connected to the drive shaft 117 via a belt mechanism 116. The belt mechanism 116 is used to transmit the rotational power of the drive motor 115, and transmit the rotation of the motor main shaft to the drive shaft 117. One end of the drive shaft 117 is connected to the eccentric wheel 108 in the cylinder body 106, which can transmit the rotational power transmitted by the belt mechanism 116 to the eccentric wheel 108, causing the eccentric wheel 108 to rotate. The rotation of the eccentric wheel 108 is converted into the reciprocating sliding of the piston 107 in the piston cylinder body 105 through the stroke adjustment structure and the cooperation of the piston connecting rod 307, providing power for the intake and compression of air.

[0032] In this embodiment, when the equipment is running, after the drive motor 115 starts, the rotational power of its main shaft is transmitted to the drive shaft 117 through the belt mechanism 116. The drive shaft 117 drives the eccentric wheel 108 to rotate synchronously. During the rotation of the eccentric wheel 108, the piston 107 is driven to slide back and forth through the stroke adjustment structure and the piston connecting rod 307. At the same time, the oil pump 401 delivers hydraulic transmission dual-purpose oil to the compression oil chamber 112 through the second oil outlet. The oil distribution plate 110 is used to make the hydraulic transmission dual-purpose oil in the compression oil chamber 112 evenly distributed, avoiding local accumulation of oil that leads to uneven pressure transmission, ensuring that the compression diaphragm 111 can be subjected to uniform thrust, pushing the compression diaphragm 111 to deform, and cooperating with the sliding of the piston 107 to realize the change of the volume of the compression chamber 102, thus completing air compression.

[0033] Please see as follows Figure 14 As shown, the present invention also provides a flow regulation method for an energy-saving compressor with a flow regulation structure, applied to the above-mentioned energy-saving compressor with a flow regulation structure, comprising the following steps: S1: The piston moves down to the bottom dead center, causing the pressure in the compression chamber to drop. The movable block 201 moves to the intake position, and air flows into the compression chamber through the external intake pipe, the intake check valve, and the airflow passage. Specifically, the drive motor 115 main shaft transmits power to the drive shaft 117 via the belt mechanism 116. The drive shaft 117 drives the eccentric wheel 108 inside the cylinder body 106 to rotate synchronously. During the rotation of the eccentric wheel 108, through the cooperation of the stroke adjustment structure and the piston connecting rod 307, its rotational motion is converted into the linear sliding of the piston 107 along the piston cylinder body 105. At this time, the rotation direction of the eccentric wheel 108 drives the piston 107 to slide downward along the inner wall of the piston cylinder body 105. During the downward sliding of the piston 107... This causes the oil-side diaphragm head 104 to move downwards synchronously, thereby gradually expanding the volume of the compression chamber 102 at the bottom of the gas-side diaphragm head 101. According to the relationship between gas pressure and volume, the internal pressure of the compression chamber 102 decreases accordingly, forming a negative pressure, which provides the power basis for the intake of external air. At the same time, the movable block 201 moves to the intake position under the action of negative pressure. At this time, the ejector pin 209 at the top of the movable block 201 moves downwards synchronously and separates from the sealing plate 210 at the bottom of the exhaust solenoid valve 207. At this time, the spring in the exhaust solenoid valve 207... Spring 211, losing the resisting force of pin 209, pushes the sealing plate 210 downward under its own elastic force, sealing the channel at the bottom of exhaust solenoid valve 207 and isolating the connecting pipe 206 from the exhaust solenoid valve 207. As movable block 201 moves down into place, the connecting pipe 206 at its top also moves synchronously with movable block 201, so that the air inlet 226 on one side of the connecting pipe 206 and the air intake check valve 212 on the side of the vent pipe 205 are on the same axis. At this time, the connecting pipe 206 and the air intake check valve 212 are on the same axis. With valve 212 connected, air enters from the external intake pipe under the suction effect of negative pressure in the compression chamber 102. It first passes through the intake check valve 212, which enables one-way airflow. After passing through the intake check valve 212, the air enters the interior of the connecting pipe 206 through the intake hole 226, and then flows downward through the connecting pipe 206 to the airflow channel 103, finally flowing into the compression chamber 102 along the airflow channel 103. The entire intake process continues until the piston 107 descends to the bottom dead center.

[0034] S2: The piston moves upward to reduce the volume of the compression chamber and compress the air. The movable block 201 moves to the exhaust position and pushes the contact block and the linkage block to squeeze the first pressure sensor to obtain real-time air pressure data. Specifically, during the upward movement of piston 107, it squeezes the hydraulic transmission dual-purpose oil in the compression oil chamber 112 at the top of the oil-side diaphragm head 104. The pressurized hydraulic transmission dual-purpose oil pushes the compression diaphragm 111 to deform through the oil distribution plate 110, causing the volume of the compression chamber 102 to gradually decrease. According to the relationship between gas pressure and volume, the air stored in the chamber is continuously compressed, and the pressure continuously increases. At the same time, the movable block 201 moves to the exhaust position under the action of pressure, and the ejector pin 209 moves upward synchronously to contact the sealing plate 210 and pushes it upward, opening the channel at the bottom of the exhaust solenoid valve 207 so that the connecting pipe 206 is connected to the exhaust solenoid valve 207. At the same time, the air inlet 226 and the air inlet check valve 21... 2. The connecting pipe 206 is separated from the intake check valve 212 to prevent the high-pressure gas after compression from leaking from the intake side. During the upward movement of the movable block 201, the four sets of first rotating seats 224 on its periphery move upward synchronously with the movable block 201. Each set of first rotating seats 224 pushes the abutment block 218 along the sliding groove 217 on the sliding seat 216 towards the linkage block 220 through the linkage rod 225 until the abutment block 218 contacts the linkage block 220. The four sets of first pressure sensors 202 on one side of the linkage block 220 contact the inner wall of the airflow channel 103. The squeezing action of the abutment block 218 enables the first pressure sensor 202 to sense the real-time air pressure data in the compression chamber 102.

[0035] S3: Obtain the preset exhaust pressure threshold, compare the real-time air pressure data with the exhaust pressure threshold, open the exhaust solenoid valve to exhaust air based on the comparison result and obtain exhaust flow data; Specifically, a preset exhaust pressure threshold is first obtained. This threshold is set according to the actual air pressure requirements of the air-using equipment. The real-time air pressure data is compared with the preset exhaust pressure threshold to determine whether the current air pressure in the compression chamber 102 meets the exhaust requirements. When the real-time air pressure data is greater than or equal to the preset exhaust pressure threshold, it indicates that the air in the compression chamber 102 has been compressed to a high pressure that meets the usage standards, and the control system outputs a comparison result of "exhaust conditions met". When the real-time air pressure data is less than the preset exhaust pressure threshold, it indicates that the air in the compression chamber 102 is not compressed enough and the air pressure does not meet the standards required by the air-using equipment, and the control system outputs a comparison result of "exhaust conditions not met". When the comparison result is "exhaust conditions met", the exhaust solenoid valve 207 is opened. At this time, the high-pressure air in the compression chamber 102 enters the external exhaust pipe through the airflow channel 103, the connecting pipe 206, and the exhaust solenoid valve 207, and is finally delivered to the air-using equipment for its use. The exhaust flow data of the discharged airflow is collected by the air flow valve 208. When the comparison result is "exhaust conditions not met", the exhaust solenoid valve 207 remains closed, and the compression chamber 102 continues to compress as the piston 107 rises until the real-time air pressure data is greater than or equal to the preset exhaust pressure threshold.

[0036] S4: Obtain preset flow demand data, match flow demand based on exhaust flow data and flow demand data, adjust piston stroke based on matching result, and cycle from S1 to S4 based on adjusted piston stroke.

[0037] Specifically, the flow demand data is expressed as an allowable deviation range. The exhaust flow data is compared with the allowable deviation range, and three matching states are obtained based on the comparison results: matched, flow is too large, and flow is too small. Matching: Exhaust flow rate data ∈ allowable deviation range indicates that the current exhaust flow rate is within the preset allowable deviation range, meaning that the current exhaust flow rate can meet the actual needs of the gas-using equipment, and there is no need to adjust the piston stroke; Excessive flow: Exhaust flow data > allowable deviation range indicates that the current exhaust flow exceeds the preset allowable deviation range. At this time, the excessive exhaust flow will not only fail to be fully utilized by the gas-using equipment, but will also cause the compressor to do extra work, resulting in energy waste. Therefore, it is necessary to reduce the exhaust flow by adjusting the structure. Low flow rate: If the exhaust flow rate is less than the allowable deviation range, it means that the current exhaust flow rate cannot meet the normal operation requirements of the gas-using equipment, which will affect the working efficiency of the gas-using equipment. Therefore, it is necessary to increase the exhaust flow rate by adjusting the structure.

[0038] When the matching result indicates that the flow rate is too high, shortening the piston stroke reduces the exhaust flow rate by decreasing the gas volume compressed by the piston in a single stroke. When the matching result indicates that the flow rate is too low, the piston stroke is extended to increase the gas volume compressed by the piston in one stroke, thereby increasing the exhaust flow rate.

[0039] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
