Abstract
Description
Technical Field
[0001] This invention relates to the field of oil quality monitoring, and in particular to a constant flow and constant pressure oil quality monitoring oil circuit regulation mechanism. Background Technology
[0002] As the lifeblood of modern industrial systems, the quality and stability of oil supply directly affect equipment operating efficiency and service life. Currently, the common practice is to install filter elements in the oil circuit, allowing the oil to be filtered as it flows through the circuit. The oil and filter elements are replaced after a specified period of equipment operation. However, the rate of oil deterioration varies under different operating conditions, which usually requires oil monitoring devices to monitor the oil status and remind personnel to replace the oil. But as more impurities are filtered out by the filter element, the resistance to oil flow in the circuit will fluctuate. High resistance will affect the monitoring data of the sensor. At the same time, as the oil circulates in the circuit, over time, impurities in the oil will adhere to the monitoring end face of the sensor, which can easily cause sensor misjudgment. Summary of the Invention
[0003] In view of the problems in the above or existing technologies, as more impurities are filtered on the filter element, the resistance of the oil flowing in the oil circuit will fluctuate. High resistance will affect the monitoring data of the sensor. At the same time, as the oil circulates in the oil circuit, over time, impurities in the oil will adhere to the monitoring end face of the sensor, which can easily cause the sensor to misjudge. Therefore, the present invention is proposed.
[0004] Therefore, the purpose of this invention is to provide a constant flow and constant pressure oil quality monitoring oil circuit regulation mechanism.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including an oil passage, a dynamic monitoring unit disposed on the oil passage, an adjustment unit disposed on the oil passage and located downstream of the dynamic monitoring unit, a filter disposed on the adjustment unit, and a power-assisted oil pump whose inlet end is connected to the outlet end of the filter and whose outlet end is connected to the adjustment unit.
[0006] As a preferred embodiment of the oil quality monitoring oil circuit adjustment mechanism for constant flow and constant pressure of the present invention, the dynamic monitoring unit includes a fixed shell disposed on the oil passage, a connecting port disposed on the fixed shell, a detection component disposed on the fixed shell and cooperating with the connecting port, and a detection auxiliary component disposed on the detection component.
[0007] As a preferred embodiment of the oil quality monitoring oil circuit adjustment mechanism for constant flow and constant pressure of the present invention, the detection component includes a detection channel disposed on the fixed shell and communicating with the communication port, an isolation cavity disposed on the fixed shell and communicating with the detection channel, and a detection terminal disposed on the isolation cavity.
[0008] As a preferred embodiment of the oil quality monitoring oil circuit adjustment mechanism of the present invention, the detection auxiliary component includes a connecting ring rotatably disposed at both ends of the inner wall of the detection channel, a fan blade disposed on the connecting ring, and a spiral scraper disposed between the two sets of connecting rings; the oil flows through the detection channel, impacting the fan blade and driving the connecting ring to rotate.
[0009] As a preferred embodiment of the oil quality monitoring oil circuit adjustment mechanism of the present invention, the adjustment unit includes a flow guiding component one and a flow guiding component two disposed on the oil passage, and a control component disposed on the flow guiding component one and the flow guiding component two.
[0010] As a preferred embodiment of the oil quality monitoring oil circuit adjustment mechanism for constant flow and pressure of the present invention, the flow guiding component one includes a connecting pipe one disposed on the oil passage, a connecting pipe two disposed on the connecting pipe one and communicating with the inlet end of the filter, a connecting cavity disposed at the connection point of the connecting pipe one and the connecting pipe two, and a sealing plate rotatably disposed in the connecting cavity and in contact with the inner wall of the connecting cavity; the flow guiding component two has the same structure as the flow guiding component one, and the connecting pipe two on the flow guiding component two is connected to the outlet end of the booster oil pump.
[0011] As a preferred embodiment of the oil quality monitoring oil circuit adjustment mechanism of the present invention, the sealing plate rotates in the connecting cavity to control the opening and closing of the connecting pipe one and the connecting pipe two.

[0013] The beneficial effects of the constant flow and constant pressure oil quality monitoring oil circuit adjustment mechanism of the present invention are as follows: The present invention monitors the oil flowing in the detection channel through the detection terminal. At the same time, the kinetic energy generated by the oil flow impacts the fan blade, which drives the spiral scraper to circulate and scrape the inner wall of the detection channel, ensuring the accuracy of the oil monitoring by the detection terminal. Meanwhile, when a large number of impurities are detected in the oil, the transmission chain controls the sealing plate to seal the oil passage between the two sets of flow guiding components, so that the oil passage is connected to the connecting pipe. With the help of the oil pump, the oil is filtered and regulated by the filter. At the same time, a small part of the oil is kept in the closed section of the oil passage to prevent the vacuum in the oil passage from causing oil pressure disturbance. After filtration, the control sealing plate seals the connecting pipe, restoring the unobstructed flow of the closed section of the oil passage, so that the oil maintains the original oil pressure and circulates in the oil passage.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0024] Reference Figure 1 - Figure 7This embodiment of the invention provides a constant flow and constant pressure oil quality monitoring oil circuit adjustment mechanism, which includes an oil passage 1, a dynamic monitoring unit 2 disposed on the oil passage 1, an adjustment unit 3 disposed on the oil passage 1 and located downstream of the dynamic monitoring unit 2, a filter 4 disposed on the adjustment unit 3, and an auxiliary oil pump 5 whose inlet end is connected to the outlet end of the filter 4 and whose outlet end is connected to the adjustment unit 3. The oil passage 1 is used as the path for oil flow, the dynamic monitoring unit 2 is used to monitor the enamel of the oil flowing in the oil passage 1, the adjustment unit 3 is used to regulate the opening and closing of the filter 4 and the oil passage 1, the filter 4 filters the oil, and the auxiliary oil pump 5 is used to increase the suction at the outlet end of the filter 4, pressurize the oil passing through the filter 4, accelerate the oil flow rate, and improve the filtration efficiency.
[0025] The dynamic monitoring unit 2 includes a fixed housing 21 disposed on the oil passage 1, a connecting port 22 disposed on the fixed housing 21, a detection component 23 disposed on the fixed housing 21 and cooperating with the connecting port 22, and a detection auxiliary component 24 disposed on the detection component 23. The fixed housing 21 serves to connect and fix the oil passage 1, and the connecting port 22 is used to connect the oil passage 1 to the detection component 23. The detection component 23 is used to monitor the quality of the flowing oil, and the detection auxiliary component 24 is used to maintain the stability of the detection performance of the detection component 23.
[0026] The detection component 23 includes a detection channel 231 disposed on the fixed housing 21 and communicating with the communication port 22, an isolation cavity 232 disposed on the fixed housing 21 and communicating with the detection channel 231, and a detection terminal 233 disposed on the isolation cavity 232. The detection channel 231 is used to connect the communication port 22 in series, so that the oil flows in the detection channel 231. The isolation cavity 232 is used to install the detection terminal 233. The detection terminal 233 is used to monitor the oil flowing through the detection channel 231.
[0027] The detection auxiliary component 24 includes a connecting ring 241 rotatably disposed at both ends of the inner wall of the detection channel 231, a fan blade 242 disposed on the connecting ring 241, and a spiral scraper 243 disposed between the two sets of connecting rings 241. The connecting ring 241 is used to rotate on the detection channel 231, the fan blade 242 is used to drive the connecting ring 241 to rotate when impacted by oil, and the spiral scraper 243 is used to cooperate with the rotation of the connecting ring 241 to circulate and scrape the inner wall of the detection channel 231 to prevent oil impurities from adhering to the inner wall of the detection channel 231. The oil flows through the detection channel 231 and impacts the fan blade 242, causing the connecting ring 241 to rotate. In this way, the kinetic energy of the oil flow is used to drive the entire detection auxiliary component 24.
[0028] The regulating unit 3 includes a flow guide component 31 and a flow guide component 32 disposed on the oil passage 1, and a control component 33 disposed on the flow guide component 31 and the flow guide component 32. The flow guide component 31 and the flow guide component 32 are used to connect the filter 4 and the power pump 5 to the oil passage 1, and the control component 33 is used to regulate the flow direction of the oil in the flow guide component 31 and control the flow of the oil in the filter 4.
[0029] The flow guiding component 31 includes a connecting pipe 311 disposed on the oil passage 1, a connecting pipe 312 disposed on the connecting pipe 311 and connected to the inlet end of the filter 4, a connecting cavity 313 disposed at the connection between the connecting pipe 311 and the connecting pipe 312, and a sealing plate 314 rotatably disposed in the connecting cavity 313 and attached to the inner wall of the connecting cavity 313. The connecting pipe 311 is used to connect the oil passage 1, the connecting pipe 312 is used to connect the filter 4 to the connecting pipe 311, and the sealing plate 314 is used to control the opening and closing of the connecting pipe 312 and the connecting pipe 311, thereby controlling the flow path of the oil. The flow guiding component 2 32 has the same structure as the flow guiding component 1 31. The connecting pipe 2 312 on the flow guiding component 2 32 is connected to the liquid outlet of the power-assisted oil pump 5. With this setting, the oil filtered by the filter 4 can be directly fed into the oil passage 1 through the power-assisted oil pump 5.
[0030] The sealing plate 314 rotates in the connecting cavity 313 to control the opening and closing of the connecting pipe 1 311 and the connecting pipe 2 312. The sealing plate 314 blocks the liquid inlet end of the connecting pipe 1 311, thus sealing the oil passage 1 between the two sets of connecting pipes 1 311. The oil in the sealed section of the oil passage 1 cannot flow, keeping the pressure of the sealed section of the oil passage 1 constant, and preventing the oil pump 5 from drawing in a vacuum in the oil passage 1.
[0031] The control component 33 includes a gear 331 rotatably mounted on and fixedly connected to the sealing plate 314; a gear 332 mounted on a set of guide components 32 and meshing with the corresponding gear 331; a transmission chain 333 mounted on the gear 332 and another set of gears 331; and a servo motor 334 mounted on the set of gears 331. The gear 331 rotates to control the sealing plate 314's closure of the connecting pipe 312, and the gear 332 drives the meshing gear 331. 1. The transmission chain 333 plays a transmission role, and the servo motor 334 is used to generate power to drive gear 1 331 to rotate. Then, through the transmission chain 333, gear 2 332 drives gear 331 to rotate. Gear 2 332 drives gear 1 331 to rotate, so that the rotation directions of the two sets of gear 1 331 are opposite, realizing the closure of oil passage 1 between the two sets of gear 1 331. At the same time, the oil enters the filter 4 through the connecting pipe 2 312. After filtration, it enters the next set of connecting pipe 2 312 from the booster oil pump 5, so that the oil flows into oil passage 1.
[0032] In summary, during the operation of the oil-using equipment, the oil circulates to cool the equipment. At this time, the oil flows in the detection channel 231, and the detection terminal 233 monitors the oil quality. Meanwhile, the sealing plate 314 seals the inlet end of the connecting pipe 312, preventing the oil from entering the filter 4 and allowing it to circulate in the oil passage 1. When the detection terminal 233 detects impurities in the oil requiring filtration, the servo motor 334 starts, driving gear 331 to rotate. Under the action of gear 332 and the transmission chain 333, the two sets of gears 33... When the rotation direction of 1 is opposite, the two sets of connecting pipes 312 are opened, and the oil passage 1 between the two sets of connecting pipes 311 is closed. At this time, the booster pump 5 starts, accelerating the oil to pass through the filter 4 for filtration. The filtered oil flows into the oil passage 1 through the booster pump 5 and continues to circulate in the oil passage 1. When the detection terminal 233 detects that the oil quality has reached the standard, the booster pump 5 stops. At the same time, the servo motor 334 drives the connecting cavity 313 to return to its original position, closing the connecting pipe 312 and connecting the closed section of the oil passage 1 to the main body of the oil passage 1, so that the oil continues to circulate along the original route.
