[0044] An oil pipe 8 is arranged between an oil outlet of the intermediate oil tank 3 and an oil inlet of the oil pump 7, so that the oil outlet of the intermediate oil tank 3 and the oil inlet of the oil pump 7 are communicated through the oil pipe 8 to realize the transmission of oil.

[0045] An air blower 6 is arranged at one side of an oil outlet of the oil pump 7, and an air blower oil tank 601 is arranged on the air blower 6, so that the oil outlet of the oil pump 7 and the oil inlet of the air blower oil tank 601 are communicated to realize the transmission of oil.

[0046] An oil inlet 102 is arranged at a top end of the oil storage tank 1, and the oil inlet 102 is communicated with the inside of the oil storage tank 1, and an oil pipe 8 is arranged between an oil outlet of the air blower oil tank 601 and the oil inlet 102, so that the oil outlet of the air blower oil tank 601 and the oil inlet 102 are communicated through the oil pipe 8.

[0047] The oil quantity control overflow device 15 is arranged at one side of the air blower oil tank 601, and the oil quantity control overflow device 15 is used to adjust the oil quantity in the air blower oil tank 601, so that the oil in the air blower oil tank 601 can continuously maintain a set oil quantity.

[0048] Through the oil quantity control overflow device 15, the oil quantity in the air blower oil tank 601 can be adjusted, and the oil quantity in the air blower oil tank 601 can be controlled to continuously maintain a set oil quantity, so as to avoid too much oil in the air blower oil tank 601 and cause safety hazards.

[0049] Meanwhile, the effective circulation of oil in the air blower oil tank 601 can be realized, and during the circulation process, the oil after running-in flushing in the air blower oil tank 601 can be filtered out, so that the air blower oil tank 601 can continuously use oil with high cleanliness, and the running-in flushing effect on the internal components of the air blower 6 can be improved.

[0050] The inside of the oil storage pool 1 is provided with an oil liquid exchange groove 14, which is fixedly connected with one side pool wall of the inside of the oil storage pool 1, and one end of the oil pipe 8 at the oil outlet of the oil storage pool 1 is located inside the oil liquid exchange groove 14 close to the lower end position.

[0051] The oil inlet of the intermediate oil tank 3 is located at the upper end position of the intermediate oil tank 3, the oil outlet of the intermediate oil tank 3 is located at the lower end position of the intermediate oil tank 3, the intermediate oil tank 3 is provided with an overflow port 301 close to the upper end position, one end of the overflow port 301 is in communication with the inside of the intermediate oil tank 3, the top end of the oil storage pool 1 is provided with a first oil hole 101, the first oil hole 101 is in communication with the inside of the oil storage pool 1, and the other end of the overflow port 301 and the first oil hole 101 are provided with an oil pipe 8, the overflow port 301 and the first oil hole 101 are in communication through the oil pipe 8.

[0052] By setting the overflow port 301, an effective safety protection effect can be achieved. Specifically, when the oil liquid in the intermediate oil tank 3 is too much and reaches the height of the overflow port 301, the oil liquid will flow back to the oil storage pool 1 through the overflow port 301, which can avoid the oil liquid in the intermediate oil tank 3 from leaking outwards due to being too much, causing waste and pollution of the environment, and even when the oil liquid in the intermediate oil tank 3 is too much, causing the pressure in the intermediate oil tank 3 to be too large, causing greater safety hazards. In addition, through the backflow of the overflow port 301, the backflow oil liquid can be purified again, further improving the purification degree of the oil liquid.

[0053] The oil outlet of the intermediate oil tank 3 is provided with a closed oil tank 4, the oil outlet of the intermediate oil tank 3 is in communication with the oil inlet of the closed oil tank 4, and the oil outlet of the closed oil tank 4 is in communication with the oil inlet of the oil pump 7. Since the closed oil tank 4 adopts a closed structure, the oil liquid can be stored in the closed oil tank 4 for a long time without being contaminated. In addition, since the closed oil tank 4 has a certain pressure, when the oil pump 7 extracts the oil liquid in the closed oil tank 4, it plays a role in assisting the transmission outward, thereby reducing the operating load of the oil pump 7, ensuring the smoothness of the oil liquid transmission, and prolonging the service life of the oil pump 7.

[0054] The upper end position of the closed oil tank 4 is provided with a pressure relief valve 402, the intermediate oil tank 3 is provided with a third oil hole 302 close to the upper end position, the third oil hole 302 is in communication with the inside of the intermediate oil tank 3, the oil inlet of the pressure relief valve 402 is in communication with the inside of the closed oil tank 4, and the oil outlet of the pressure relief valve 402 and the third oil hole 302 are provided with an oil pipe 8, the oil outlet of the pressure relief valve 402 and the third oil hole 302 are in communication through the oil pipe 8. By setting the pressure relief valve 402, when the pressure in the closed oil tank 4 is too large, the oil liquid will flow back through the pressure relief valve 402 to avoid safety hazards. At the same time of pressure relief, the oil liquid will flow back to the inside of the intermediate oil tank 3 through the oil pipe 8, avoiding the oil liquid flowing to the outside environment due to pressure relief, causing waste and pollution of the oil liquid.

[0055] The oil outlet side of the closed oil tank 4 is provided with an oil pollution detector 5, the oil outlet of the closed oil tank 4 is communicated with the oil inlet of the oil pollution detector 5, and the oil outlet of the oil pollution detector 5 is communicated with the third oil hole 302.

[0056] The oil pollution detector 5 can effectively detect the purified oil, and can monitor the cleanliness of the purified oil in real time, thereby further ensuring the safety and reliability of the air blower running-in flushing. The detected oil sequentially passes through the oil pipe 8 and the third oil hole 302 and enters the inside of the intermediate oil tank 3, thereby avoiding waste of oil.

[0057] The oil amount control overflow device 15 comprises an overflow oil storage box 10, and the overflow oil storage box 10 is located at a transverse side of the air blower tank 601.

[0058] The lower end of the overflow oil storage box 10 is provided with a fifth oil hole 1002, and the fifth oil hole 1002 is communicated with the inside of the overflow oil storage box 10.

[0059] The air blower tank 601 is provided with a U-shaped pipe 11 between the oil outlet and the fifth oil hole 1002, one end of the U-shaped pipe 11 is communicated with the oil outlet of the air blower tank 601, the other end of the U-shaped pipe 11 extends to the inside of the overflow oil storage box 10 through the fifth oil hole 1002, and the port position of the U-shaped pipe 11 in the inside of the overflow oil storage box 10 is located in the height range of the inside of the air blower tank 601. According to the actual oil amount requirement, the port height of the U-shaped pipe 11 in the inside of the overflow oil storage box 10 is adjusted to adjust the oil amount in the inside of the air blower tank 601, so that the oil height in the inside of the air blower tank 601 is equal to the port height of the U-shaped pipe 11 in the inside of the overflow oil storage box 10.

[0060] The lower end of the overflow oil storage box 10 is provided with a fourth oil hole 1001, one end of the fourth oil hole 1001 is communicated with the inside of the overflow oil storage box 10, and the other end of the fourth oil hole 1001 is communicated with the oil inlet 102 through the oil pipe 8.

[0061] When the oil in the air blower tank 601 is excessive, the oil will overflow to the overflow oil storage box 10 through the U-shaped pipe 11, and then the oil in the overflow oil storage box 10 will flow back to the inside of the oil storage pool 1 through the oil pipe 8 and the oil inlet 102 in sequence. On the one hand, the effective circulation of the oil in the air blower tank 601 is realized, and the oil in the air blower tank 601 after running-in flushing can be filtered during the circulation process. On the other hand, the excessive oil in the air blower tank 601 is avoided, and the safety hazard is avoided.

[0062] The oil outlet side of the air blower oil tank 601 is provided with a valve 9, one end of the valve 9 communicates with the oil outlet of the air blower oil tank 601, and the other end of the valve 9 communicates with the oil inlet 102 through the oil pipe 8. During the air blower running-in flushing process, the valve 9 is in a closed state to ensure the normal operation of the running-in flushing. When the air blower running-in flushing is completed, the valve 9 is opened, and the oil in the air blower oil tank 601 flows back to the inside of the oil storage pool 1 through the oil pipe 8, the oil inlet 102 in sequence, completing the running-in flushing process of the internal components of the air blower 6. In addition, the valve 9 also plays the role of an emergency switch. When a fault occurs and the oil in the air blower oil tank 601 is too much, the oil in the air blower oil tank 601 can be actively discharged by opening the valve 9, avoiding safety hazards.

[0063] The upper end position of the overflow oil receiving box 10 is provided with a vent 1003, one end of the vent 1003 communicates with the inside of the overflow oil receiving box 10, and the other end of the vent 1003 is provided with a gas pressure balance pipe 13, the gas pressure balance pipe 13 communicates with the vent 1003, and the other end of the gas pressure balance pipe 13 communicates with the outside atmosphere. The inside of the overflow oil receiving box 10 is communicated with the outside atmosphere through the gas pressure balance pipe 13, which can ensure that the function of the oil amount control overflow device 15 is maintained effectively.

[0064] The oil inlet 102 at the top end position of the oil storage pool 1 is located away from the oil liquid exchange groove 14. When the backflow oil flows back to the inside of the oil storage pool 1 through the oil inlet 102, since the oil inlet 102 and the oil liquid exchange groove 14 are located at two side positions of the oil storage pool 1 respectively, it can avoid that the impurities in the oil flowing back to the inside of the oil storage pool 1 fall into the inside of the oil liquid exchange groove 14, further ensuring the cleanliness of the oil in the oil liquid exchange groove 14, avoiding that the particulate impurities in the backflow oil fall into the oil liquid exchange groove 14, and affecting the oil purification effect of the oil purification device 2 when the oil purification device 2 extracts the oil mixed with impurities.

[0065] The air blower oil tank 601 is provided with an overflow hole 16 near the upper end, one end of the overflow hole 16 communicates with the inside of the air blower oil tank 601, and the other end of the overflow hole 16 is provided with an overflow pipe 12, one end of the overflow pipe 12 communicates with the overflow hole 16, and the other end of the overflow pipe 12 communicates with the vent 1003. When the oil in the air blower oil tank 601 is too much due to a fault and reaches the position of the overflow hole 16, the oil will flow into the inside of the overflow oil receiving box 10 through the overflow hole 16, the overflow pipe 12, the vent 1003 in sequence, and then enter the inside of the oil storage pool 1 through the fourth oil hole 1001, the oil pipe 8 and the oil inlet 102 in sequence, completing the entire overflow process, and avoiding damage to the air blower due to too much oil in the air blower oil tank 601.

[0066] The oil flow detection device 17 is arranged on the U-shaped pipe 11. During the whole break-in flushing process, the oil pump 7 needs to continuously transmit oil to the air blower oil tank 601, and through the communication principle of the U-shaped pipe 11, the oil in the air blower oil tank 601 continuously flows to the inside of the overflow oil storage box 10 through the U-shaped pipe 11, so that a continuous oil flow is formed in the U-shaped pipe 11 during the break-in flushing process. The oil flow detection device 17 is used for monitoring the oil flow in the U-shaped pipe 11 in real time, and an alarm is arranged on the oil flow detection device 17. When the oil flow detection device 17 detects that the oil flow in the U-shaped pipe 11 stops, it means that the corresponding oil passage of the U-shaped pipe 11 is blocked, at this time, the alarm is triggered, and the oil pump 7 is controlled to stop running. After the operation personnel repair the blocked oil passage, the oil pump is started again to restore normal oil transmission. In this way, the continuous increase of the oil in the air blower oil tank 601 due to the blockage of the corresponding oil passage of the U-shaped pipe 11 is avoided, and the safety hazard is caused.

[0067] A break-in flushing method of an air blower, comprising the following steps:

[0068] Step (1): Close the valve 9, add oil into the inside of the oil storage pool 1 through the oil inlet 102 on the oil storage pool 1, and the oil exchange groove 14 is located in the inside of the oil.

[0069] Step (2): Start the oil purification device 2, the oil purification device 2 extracts the oil in the oil exchange groove 14 in the oil storage pool 1, and the oil is introduced into the oil purification device 2 through the oil pipe 8, and the oil purification device 2 purifies the gas, liquid and solid three-state pollutants in the oil.

[0070] Since the oil inlet 102 and the oil exchange groove 14 are located at two positions on the inside of the oil storage pool 1 respectively, when the oil is added into the inside of the oil storage pool 1 through the oil inlet 102 on the oil storage pool 1, the large particle impurities in the oil will directly deposit at the bottom of the oil storage pool 1, and will not enter the inside of the oil exchange groove 14, so that the oil extracted by the oil purification device 2 is not mixed with large particle impurities, and the oil purification effect of the oil purification device 2 is affected.

[0071] Step (3): The purified oil successively passes through the oil outlet on the oil purification device 2, the oil pipe 8, and the oil inlet on the intermediate oil tank 3, and is introduced into the inside of the intermediate oil tank 3, and then successively passes through the oil outlet on the intermediate oil tank 3 and is introduced into the inside of the closed oil tank 4. Since the closed oil tank 4 adopts a closed structure, the oil can be stored in the closed oil tank 4 for a long time and is not polluted.

[0072] When the oil in the inside of the intermediate oil tank 3 is too much and the liquid level reaches the position of the overflow port 301, the oil successively flows back to the inside of the oil storage pool 1 through the overflow port 301, the oil pipe 8 and the first oil hole 101, and plays a role of automatic overflow oil backflow.

[0073] Step (4): The oil pump 7 extracts the oil in the closed oil tank 4, and transmits the oil in the closed oil tank 4 to the blower tank 601 through the oil pipe 8. The blower 6 runs, and the oil is circulated in the inside of the blower to perform the break-in flushing of the internal components of the blower 6.

[0074] Since the overflow oil receiving box 10 is arranged on one side of the blower tank 601, and the blower tank 601 and the overflow oil receiving box 10 are in balance communication through the U-shaped pipe 11, according to the actual oil demand, the oil amount in the blower tank 601 is adjusted by adjusting the port height of the U-shaped pipe 11 in the overflow oil receiving box 10. The oil level in the blower tank 601 and the port height of the U-shaped pipe 11 in the overflow oil receiving box 10 are kept in the same height through the U-shaped pipe 11.

[0075] Step (5): The oil pump 7 continuously extracts the oil in the closed oil tank 4, and continuously transmits the oil to the inside of the blower tank 601. When the oil in the blower tank 601 is too much, the oil will overflow to the overflow oil receiving box 10 through the U-shaped pipe 11. Then, the oil in the overflow oil receiving box 10 flows back to the inside of the oil storage pool 1 through the oil pipe 8 and the oil inlet 102 in turn. On the one hand, the effective circulation of the oil in the blower tank 601 is realized, and the oil in the blower tank 601 after the break-in flushing can be filtered out during the circulation process. On the other hand, the safety hazard of too much oil in the blower tank 601 is avoided.

[0076] At the same time, part of the oil in the closed oil tank 4 will enter the inside of the oil pollution degree detector 5 through the oil pipe 8. The oil pollution degree detector 5 detects the purification effect of the entering oil, and monitors the cleanliness of the purified oil in real time. The detected oil enters the inside of the intermediate oil tank 3 through the oil pipe 8 and the third oil hole 302 in turn.

[0077] Step (6): After the break-in flushing is completed, the oil pump 7 is closed, and the valve 9 is opened. The oil in the blower tank 601 flows back to the inside of the oil storage pool 1 through the oil pipe 8 and the oil inlet 102 in turn, and the break-in flushing process of the internal components of the blower 6 is completed.

[0078] The break-in flushing device can simultaneously connect multiple blowers 6 for break-in flushing operation. The oil amount control overflow device 15 and the valve 9 are respectively arranged on one side of each blower 6. Each group of blowers 6 and the corresponding oil amount control overflow device 15 and valve 9 are connected in parallel between the oil outlet end of the oil pump 7 and the oil inlet 102 of the oil storage pool 1.

[0079] The above are only specific embodiments of the present application, and cannot limit the scope of the present application. The replacement of equivalent components or equivalent changes and modifications made within the scope of the patent protection of the present application shall still fall within the scope of the claims of the present application.
