Description

Technical Field

[0001] The invention relates to the technical field of air compressors, and in particular to an oil supply and lubrication device for an air compressor. Background Art

[0002] An air compressor is a device that sucks air from the atmosphere and compresses it to a higher pressure through mechanical action. It is widely used in many fields such as industrial production, automobile maintenance, household cleaning, medical equipment, etc. According to different working principles, air compressors can be mainly divided into piston compressors, centrifugal compressors, etc. Among them, the lubrication of air compressors is very important, which helps to reduce wear, improve efficiency and extend the service life of the machine. For piston compressors, there is friction between the cylinder and the piston, so lubrication can prevent overheating and wear.

[0003] In the existing patent CN118775216A, a piston air compressor is disclosed, including a shell, a crankshaft structure is provided in the shell; the upper end of the crankshaft structure is connected to a movable plate that can move up and down, the upper end of the movable plate is fixedly connected to a push rod, and a storage member is provided in the shell; the upper end of the push rod passes through the storage member and is connected to a piston member; a conveying member is provided in the piston member, a rotating member is provided in the piston member, and one end of the rotating member is connected to the conveying member; a lubricating member is provided on the piston member, and the lubricating member is connected to the rotating member, and a conducting member is connected to the conveying member, and the output end of the conducting member is above the lubricating member; a connecting member is provided in the shell, and a rotating member is connected to the connecting member.

DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] Embodiment 1:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, an oil supply and lubrication device for an air compressor of the present invention comprises a support frame 1, on which a compression cylinder 2 and a storage cylinder 3 connected to the compression cylinder 2 are arranged, a connecting pipe is arranged between the compression cylinder 2 and the storage cylinder 3, a valve control is arranged on the connecting pipe, an air delivery pipe 4 for conveying air is arranged on the compression cylinder 2, and an air supply pipe 5 for supplying compressed air is arranged on the storage cylinder 3;

[0035] The support frame 1 is provided with a driving mechanism 6, and the driving mechanism 6 is provided with a compression assembly 7 adapted to the compression cylinder 2, and the compression assembly 7 rubs against the compression cylinder 2;

[0036] An oil supply assembly 8 is provided on the compression cylinder 2, a detection assembly 9 for detecting temperature is provided on the compression assembly 7, an expansion assembly 10 is provided on the detection assembly 9, an oil delivery assembly 11 connected with the oil supply assembly 8 is provided on the compression cylinder 2, the expansion assembly 10 is located in the oil delivery assembly 11, an oil storage assembly 12 connected with the oil delivery assembly 11 and the storage cylinder 3 is provided on the compression cylinder 2, a pushing assembly 13 is provided in the oil storage assembly 12, an oil injection assembly 14 connected with the oil storage assembly 12 is provided in the compression cylinder 2, and the oil injection assembly 14 injects oil onto the compression assembly 7.

[0037] Working principle: Fill the oil supply component 8 with lubricating oil. When compressing air, continuously input air into the compression cylinder 2 through the air pipe 4, start the driving mechanism 6, force the compression component 7 to move back and forth, so that the compression component 7 compresses the air in the compression cylinder 2. When the air is compressed to a reasonable pressure, it is released into the storage cylinder 3 for storage, and the compressed air is provided to other equipment through the air supply pipe 5. Due to the back and forth friction between the compression component 7 and the inner wall of the compression cylinder 2, heat is generated, causing the temperature of the compression component 7 to rise. When the temperature rises above the set value, it is detected by the detection component 9 and the temperature is transmitted to the expansion component 10. The expansion component 10 expands, forcing the oil delivery component 11 to deliver the lubricating oil to the oil storage component 12. When the compression component 7 moves to the position of the oil injection component 14, the compressed air is introduced into the oil storage component 12, forcing the compressed air to drive the push component 13 to move, forcing the push component 13 to push the lubricating oil in the oil storage component 12 to the oil injection component 14. Under the high pressure of the compressed gas, the oil injection component 14 is forced to spray the lubricating oil onto the compression component 7 to cool the compression component 7. When the compression component 7 cools down, the detection component 9 is forced to detect and transfer the temperature to the expansion component 10. At this time, the expansion component 10 contracts, forcing The oil delivery component 11 is retracted, so that the lubricating oil in the oil supply component 8 continuously enters the oil delivery component 11 to a reasonable position, and prepares for providing lubricating oil to the oil storage component 12. At the same time, the oil storage component 12 and the storage cylinder 3 are disconnected, so that the pushing component 13 is retracted to the original position, and the above steps are repeated. When the temperature is high, the lubricating oil is continuously sprayed out, and when the temperature is low, the lubricating oil is continuously replenished. In summary, an air compressor oil supply and lubrication device of the present application can adjust the temperature of the compression component 7 according to the temperature generated by the friction heat between the compression component 7 and the compression cylinder 2, and when the temperature is high, the lubricating oil is transported to the oil storage by using the temperature. Component 12 uses the high pressure of compressed air to push the lubricating oil to the oil injection component 14 for spraying. The higher the temperature, the more lubricating oil is delivered and the more lubricating oil is sprayed, thereby achieving the effects of rapid cooling and reasonable use of lubricating oil. At the same time, at low temperatures, the temperature can be used to replenish the lubricating oil of the oil supply component 8 in the oil delivery component 11, which is convenient for transporting the lubricating oil to the oil storage component 12 at high temperatures, thereby adjusting the supply of lubricating oil according to the temperature of the compression component 7 itself, ensuring that the equipment works within a reasonable range, facilitating efficient operation of the equipment, ensuring the optimal performance of the equipment, improving the overall efficiency of the equipment, and increasing the service life of the equipment.

[0045] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an oil supply and lubrication device for an air compressor of the present invention, the oil storage assembly 12 includes an oil storage cylinder 1201 arranged on the compression cylinder 2, an air guide pipe 1202 connected to the storage cylinder 3 is arranged at the end of the oil storage cylinder 1201, a solenoid valve 1203 is arranged on the air guide pipe 1202, a pressure relief valve 1204 is arranged on the oil storage cylinder 1201, an oil guide pipe 1205 is arranged at the other end of the oil storage cylinder 1201, a one-way valve 1206 is installed on the oil guide pipe 1205, the oil storage cylinder 1201 is connected to the oil delivery pipe 1106, and the oil guide pipe 1205 is connected to the oil injection assembly 14.

[0046] like Figure 7 As shown, an oil supply and lubrication device for an air compressor of the present invention, the pushing component 13 includes a partition 1301 arranged inside an oil storage cylinder 1201, a pushing rod 1302 is arranged on the partition 1301, a pneumatic piston 1303 is arranged at the end of the pushing rod 1302, a spring 1304 sleeved on the outer ring of the pushing rod 1302 is arranged between the pneumatic piston 1303 and the partition 1301, and an oil pushing piston 1305 is arranged at the other end of the pushing rod 1302, wherein lubricating oil is loaded between the oil pushing piston 1305 and the oil storage cylinder 1201, and gas is loaded between the pneumatic piston 1303 and the oil storage cylinder 1201.

[0047] like Figure 2 , Figure 5 and Fig.10As shown, an oil supply and lubrication device for an air compressor of the present invention, the oil injection assembly 14 includes an annular tube 1401 arranged on the inner wall of the compression cylinder 2, the annular tube 1401 is connected to the oil guide pipe 1205, the inner wall of the annular tube 1401 is connected to a plurality of evenly distributed oil distribution pipes 1402, and an oil nozzle 1403 is installed on the oil distribution pipe 1402, wherein when the compression piston 703 moves to the oil nozzle 1403, the output end of the oil nozzle 1403 is aligned with the compression piston 703.

[0048] Working principle: The supply pipe 803 is connected with the lubricating oil supply device so that the oil supply tank 802 is filled with lubricating oil. When compressing air, the air is continuously input into the compression cylinder 2 through the air pipe 4, and the motor 602 is started. The output shaft of the motor 602 rotates to drive the cam 603 to rotate, and the rotation of the cam 603 drives the shaft 604 to rotate. The shaft 604 drives the connecting rod 605 to continuously reciprocate back and forth, forcing the connecting rod 605 to drive the compression rod 701 to reciprocate back and forth in a straight line. The compression rod 701 drives the piston base 702 to move back and forth, forcing the piston base 702 to drive the compression piston 703 to move back and forth, so that the compression piston 703 continuously compresses the input air until the air is compressed to a reasonable pressure to form compressed air, forcing the compression cylinder 2 to be connected with the storage cylinder 3, so that the compressed air is stored in the storage cylinder 3, and the compressed air is provided to other equipment for use through the air supply pipe 5;

[0049] Since the inner wall of the compression cylinder 2 and the compression piston 703 generate heat due to the back and forth friction, the temperature of the compression piston 703 rises, forcing the temperature of the piston base 702 to rise. When the temperature rises above the set value, the heat-conducting rod 903 transfers heat to the metal hose 901, and the metal hose 901 can be evacuated to reduce the boiling point of the working liquid, so that the working liquid in the metal hose 901, such as water, absorbs heat and evaporates at a higher temperature, so that the water vapor carries heat to the other end of the metal hose 901 and gathers. Under the heat transfer effect of the heat exchange shell 1001 and the heat transfer rod 1002, the heat is transferred to the expansion airbag 1003, causing the expansion airbag 1003 to expand, thereby reducing the oil supply cylinder 1101. The space at the bottom causes the pressure to increase, so that the gas acts on the force piston 1105, forcing the force piston 1105 to move. Under the action of the partition 1102, the oil delivery rod 1103 is driven to move, and the oil delivery rod 1103 drives the oil delivery piston 1104 to move, forcing the oil delivery piston 1104 to squeeze the lubricating oil in the oil delivery cylinder 1101. Under the action of the oil delivery pipe 1106 and the one-way valve 1107, the lubricating oil is forced to be continuously delivered into the oil storage cylinder 1201; when the heat exchange is completed, the water vapor releases heat and condenses into liquid. Under the capillary action of the liquid absorption core 902, the liquid quickly returns to the end of the metal hose 901, forcing the water to continuously transfer heat until the lubricating oil in the oil storage cylinder 1201 reaches a certain value;

[0050] The compression piston 703 is sprayed with oil. When the compression piston 703 moves to the oil injection nozzle 1403, the solenoid valve 1203 is opened. Since the compressed air is stored in the storage cylinder 3 and the pressure is relatively high, the compressed air is forced to enter the oil storage cylinder 1201 through the air guide pipe 1202. The compressed air acts on the pneumatic piston 1303, causing the pneumatic piston 1303 to move quickly, driving the push rod 1302 to move quickly, and compressing the spring 1304, causing the push rod 1302 to drive the oil push piston 1305 to move. At this time, the one-way valve 3 1206 is opened. Under the action of the oil guide pipe 1205, the oil push piston 1305 quickly pushes the lubricating oil into the annular tube 1401, and the lubricating oil is introduced into the oil injection nozzle 1403 through the oil distribution pipe 1402. The lubricating oil is sprayed onto the compression piston 703 through the oil injection nozzle 1403, and the compression piston 703 is lubricated and cooled.

[0051] Close the solenoid valve 1203, open the pressure relief valve 1204, discharge the compressed air in the oil storage cylinder 1201, and under the action of the spring 1304, the starting piston and the pushing piston return to their original positions. Due to the insufficient amount of lubricating oil in the oil delivery cylinder, the lubricating oil will not enter the oil storage cylinder 1201 during the process of pushing the piston to retreat;

[0052] When the compression piston 703 cools down, the temperature of the piston base 702 also drops, and the heat transfer effect between the metal hose 901 and the heat conducting rod 903 is not formed, so that the temperature of the heat exchange shell 1001 drops, and the temperature of the heat transfer rod 1002 drops. At this time, the expansion airbag 1003 contracts, forcing the force-bearing piston 1105 to move backward. Under the action of the partition 1102, the oil delivery rod 1103 is driven to move backward, and the oil delivery rod 1103 drives the oil delivery piston 1104 to move backward, forcing the volume inside the oil delivery cylinder 1101 and the oil delivery piston 1104 to increase and the pressure to decrease. Under the action of the oil supply pipe 804 and the one-way valve 805, the lubricating oil in the oil supply tank 802 is forced to be continuously transported to the oil delivery cylinder, preparing to provide lubricating oil for the oil storage cylinder 1201. Repeat the above steps. When the temperature is high, the lubricating oil is continuously sprayed out, and when the temperature is low, the lubricating oil is continuously replenished.

[0053] The setting of the driving mechanism 6 can provide power, so that the rotational force is converted into linear reciprocating motion, so that the compression component 7 moves back and forth, thereby realizing the compression effect on the air and continuously forming compressed air; the setting of the compression component 7 can realize the compression effect on the air, so that the air is continuously compressed into compressed air for storage, and at the same time, the cooperation between the piston base 702 and the compression piston 703 realizes the sealing effect, and the friction between the compression piston 703 and the compression cylinder 2 generates heat, which can have an effect on the detection component 9; the setting of the oil supply component 8 can continuously provide lubricating oil, so that the device can continuously use lubricating oil, and the setting of the supply pipe 803 can continuously replenish the lubricating oil, avoid the lack of oil resulting in the inability to lubricate and cool down, improve the rationality of the device, and the one-way valve 8 The setting of 05 prevents the oil in the oil delivery cylinder from flowing back into the oil supply tank 802; the setting of the oil delivery component 11 can realize the conveying effect of the lubricating oil, and convey the lubricating oil to the oil storage cylinder 1201, so as to realize the excessive effect of the lubricating oil, and at the same time can store the lubricating oil.

[0054] This solution can adjust the temperature of the compression piston 703 and the piston base 702 according to the temperature generated by the heat generated by the friction between the compression piston 703 and the compression cylinder 2. When the temperature is high, the temperature difference is used to transport the lubricating oil to the oil storage cylinder 1201, and the high pressure of the compressed air is used to pump the lubricating oil to the oil nozzle 1403 for spraying. The higher the temperature, the more lubricating oil is transported, and the more lubricating oil is forced to be sprayed, thereby achieving the effects of rapid cooling and reasonable use of the lubricating oil. At the same time, when the temperature is low, the temperature difference can be used to replenish the lubricating oil in the oil supply tank 802 to the oil delivery cylinder, which is convenient for transporting the lubricating oil to the oil storage cylinder 1201 when the temperature is high, thereby achieving the adjustment of the lubricating oil supply according to the temperature of the compression piston 703 and the piston base 702, ensuring that the equipment operates within a reasonable temperature range, facilitating the efficient operation of the equipment, ensuring the optimal performance of the equipment, improving the overall efficiency of the equipment, and increasing the service life of the equipment.
