[0013] Preferably, the oil filling port at the top end of the oil storage tank is located away from one side of the oil exchange tank.

[0014] A running-in flushing method for a blower running-in flushing device comprises the following steps: Step (1): close the valve, add oil into the oil reservoir through the oil filling port on the oil reservoir, and the oil exchange tank is located inside the oil; Step (2): starting the oil purification device, which extracts oil from the oil exchange tank in the oil storage tank and passes the oil into the oil purification device through the oil pipe. The oil purification device purifies the gas, liquid and solid pollutants in the oil; Since the oil filling port and the oil exchange tank are located at two sides of the oil storage tank, when oil is added to the oil storage tank through the oil filling port on the oil storage tank, large particles of impurities in the oil will directly settle to the bottom of the oil storage tank, and will not enter the oil exchange tank. Therefore, it can be avoided that the oil extracted by the oil purification device is mixed with large particles of impurities, which will affect the oil purification effect of the oil purification device; Step (3): the purified oil enters the interior of the intermediate oil tank through the oil outlet on the oil purification device, the oil pipe, and the oil inlet on the intermediate oil tank in sequence, and then enters the interior of the closed oil tank through the oil outlet on the intermediate oil tank in sequence. Since the closed oil tank adopts a closed structure, it can ensure that the oil is stored in the closed oil tank for a long time and is not contaminated; When there is too much oil in the intermediate oil tank and the liquid level reaches the overflow port, it will flow back to the inside of the oil storage tank through the overflow port, the oil pipe, and the first oil hole in sequence, playing the role of automatic overflow oil return; Step (4): the oil pump extracts the oil in the closed oil tank and transmits the oil in the closed oil tank to the blower oil tank through the oil pipe. The blower runs and the oil circulates inside the blower to run-in and flush the internal components of the blower. Since an overflow oil receiving box is provided on one side of the blower oil tank, and the blower oil tank and the overflow oil receiving box are balancedly connected via a U-shaped tube, the oil volume inside the blower oil tank is adjusted by adjusting the port height of the U-shaped tube inside the overflow oil receiving box according to the actual oil volume demand, and the oil height inside the blower oil tank is made equal to the port height of the U-shaped tube inside the overflow oil receiving box via the U-shaped tube; Step (5): The oil pump continuously extracts the oil from the closed oil tank and continuously transports the oil to the blower oil tank. When there is too much oil in the blower oil tank, the oil will overflow into the overflow oil storage box through the U-shaped pipe. Then, the oil in the overflow oil storage box will flow back to the inside of the oil storage tank through the oil pipe and the oil filling port in sequence. On the one hand, the effective circulation of the oil in the blower oil tank is achieved. During the circulation process, the oil in the blower oil tank after running-in and flushing can be filtered out. On the other hand, excessive oil in the blower oil tank is avoided to prevent safety hazards. At the same time, part of the oil in the closed oil tank will enter the oil contamination detector through the oil pipe. The oil contamination detector will detect the purification effect of the incoming oil and monitor the cleanliness of the purified oil in real time. The tested oil will enter the middle oil tank through the oil pipe and the third oil hole in turn. Step (6): After the running-in and flushing are completed, the oil pump is turned off and the valve is opened. The oil inside the blower oil tank flows back to the oil reservoir through the oil pipe and the oil filling port in sequence, completing the running-in and flushing process of the internal components of the blower.

[0015] The beneficial effects of the present invention are: 1. Since an overflow oil receiving box is provided at one lateral side of the blower oil tank, a U-shaped tube is provided between the oil outlet of the blower oil tank and the fifth oil hole, one end of the U-shaped tube is connected to the oil outlet of the blower oil tank, and the other end of the U-shaped tube extends to the inside of the overflow oil receiving box through the fifth oil hole, and the port position of the U-shaped tube located inside the overflow oil receiving box is located within the height range inside the blower oil tank. According to the actual oil quantity demand, the port height of the U-shaped tube inside the overflow oil receiving box is adjusted to adjust the oil quantity inside the blower oil tank, so that the oil height inside the blower oil tank is equal to the port height of the U-shaped tube inside the overflow oil receiving box; Furthermore, since a fourth oil hole is provided at the lower end of the overflow oil receiving box, one end of the fourth oil hole is connected to the interior of the overflow oil receiving box, and the other end of the fourth oil hole is connected to the oil filling port through the oil pipe; When there is too much oil in the blower oil tank, the oil will overflow into the overflow oil collection box through the U-shaped pipe, and then the oil in the overflow oil collection box will flow back to the inside of the oil storage tank through the oil pipe and the oil filling port in turn. On the one hand, the effective circulation of the oil in the blower oil tank is realized. During the circulation process, the oil after running-in and flushing in the blower oil tank can be filtered out. On the other hand, excessive oil in the blower oil tank is avoided to avoid safety hazards.

[0016] 2. By setting a closed oil tank between the intermediate oil tank and the oil pump, since the closed oil tank adopts a closed structure, it can ensure that the oil is stored inside the closed oil tank for a long time without being contaminated. In addition, since there is a certain pressure inside the closed oil tank, when the oil pump draws the oil inside the closed oil tank, it plays a role of assisting transmission to the outside, thereby reducing the operating load of the oil pump, ensuring the smoothness of oil transmission, and at the same time increasing the service life of the oil pump.

[0017] 3. By installing an oil contamination detector at the oil outlet of the closed oil tank, the purified oil can be effectively tested and the cleanliness of the purified oil can be monitored in real time, which provides further protection for the safety and reliability of the blower running-in and flushing. The tested oil enters the interior of the intermediate oil tank through the oil pipe and the third oil hole in turn to avoid oil waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The oil quantity control overflow device 15 comprises an overflow oil receiving box 10 , and the overflow oil receiving box 10 is located at one lateral side of the blower oil tank 601 .

[0040] A fifth oil hole 1002 is provided at the lower end of the overflow oil receiving box 10 , and the fifth oil hole 1002 is communicated with the interior of the overflow oil receiving box 10 .

[0041] A U-shaped tube 11 is provided between the oil outlet of the blower oil tank 601 and the fifth oil hole 1002, one end of the U-shaped tube 11 is connected to the oil outlet of the blower oil tank 601, and the other end of the U-shaped tube 11 extends to the interior of the overflow oil receiving box 10 through the fifth oil hole 1002, and the port position of the U-shaped tube 11 located inside the overflow oil receiving box 10 is located within the height range inside the blower oil tank 601. According to the actual oil volume demand, the port height of the U-shaped tube 11 inside the overflow oil receiving box 10 is adjusted to adjust the oil volume inside the blower oil tank 601, so that the oil height inside the blower oil tank 601 is equal to the port height of the U-shaped tube 11 inside the overflow oil receiving box 10.

[0042] A fourth oil hole 1001 is provided at the lower end of the overflow oil receiving box 10 , one end of the fourth oil hole 1001 is connected to the interior of the overflow oil receiving box 10 , and the other end of the fourth oil hole 1001 is connected to the oil filling port 102 through the oil pipe 8 .

[0043] When there is too much oil in the blower oil tank 601, the oil will overflow into the overflow oil storage box 10 through the U-shaped tube 11, and then the oil in the overflow oil storage box 10 will flow back to the inside of the oil storage tank 1 through the oil pipe 8 and the oil filling port 102 in turn. On the one hand, the effective circulation of the oil in the blower oil tank 601 is realized. During the circulation process, the oil after running-in and flushing in the blower oil tank 601 can be filtered out. On the other hand, excessive oil in the blower oil tank 601 is avoided to prevent safety hazards.

[0044] A valve 9 is provided on one side of the oil outlet of the blower oil tank 601, one end of the valve 9 is connected to the oil outlet of the blower oil tank 601, and the other end of the valve 9 is connected to the oil filling port 102 through the oil pipe 8. During the blower running-in and flushing process, the valve 9 is in a closed state to ensure the normal operation of the running-in and flushing. When the blower running-in and flushing is completed, the valve 9 is opened, and the oil inside the blower oil tank 601 flows back to the inside of the oil storage tank 1 through the oil pipe 8 and the oil filling port 102 in turn, completing the running-in and flushing process of the internal components of the blower 6. In addition, the valve 9 also serves as an emergency switch. When a fault occurs, resulting in excessive oil in the blower oil tank 601, the oil in the blower oil tank 601 can be actively discharged by opening the valve 9 to avoid safety hazards.

[0045] An air vent 1003 is provided at the upper end of the overflow oil storage box 10, one end of the air vent 1003 is connected to the interior of the overflow oil storage box 10, and the other end of the air vent 1003 is provided with an air pressure balance pipe 13, the air pressure balance pipe 13 is connected to the air vent 1003, and the other end of the air pressure balance pipe 13 is connected to the external atmosphere.

[0046] The oil filling port 102 at the top of the oil storage tank 1 is located at a position far away from the oil exchange tank 14. When the refluxed oil flows back to the oil storage tank 1 through the oil filling port 102, since the oil filling port 102 and the oil exchange tank 14 are respectively located on both sides of the oil storage tank 1, impurities in the oil refluxed to the oil storage tank 1 can be prevented from falling into the oil exchange tank 14, further ensuring the cleanliness of the oil in the oil exchange tank 14, and preventing particulate impurities in the refluxed oil from falling into the oil exchange tank 14, which affects the oil purification effect of the oil purification device 2 when the oil purification device 2 extracts the oil contaminated with impurities.

[0047] An overflow hole 16 is provided near the upper end of the blower oil tank 601, one end of the overflow hole 16 is connected to the interior of the blower oil tank 601, and an overflow pipe 12 is provided at the other end of the overflow hole 16, one end of the overflow pipe 12 is connected to the overflow hole 16, and the other end of the overflow pipe 12 is connected to the vent 1003. When there is too much oil in the blower oil tank 601 due to a malfunction and it reaches the overflow hole 16, the oil will flow to the interior of the overflow oil storage box 10 through the overflow hole 16, the overflow pipe 12, and the vent 1003 in sequence, and then enter the interior of the oil storage tank 1 through the fourth oil hole 1001, the oil pipe 8, and the oil filling port 102 in sequence, completing the entire overflow process to avoid damage to the blower due to excessive oil in the blower oil tank 601.

[0048] The U-shaped tube 11 is provided with an oil flow detection device 17. Due to the entire running-in and flushing process, the oil pump 7 needs to continuously transmit oil to the blower oil tank 601. Through the communicating vessel principle of the U-shaped tube 11, the oil in the blower oil tank 601 continuously flows through the U-shaped tube 11 to the inside of the overflow oil storage box 10. Therefore, during the running-in and flushing process, a continuous oil flow will be formed in the U-shaped tube 11. The oil flow detection device 17 is used to monitor the oil flow in the U-shaped tube 11 in real time. An alarm is installed on the oil flow detection device 17. When the oil flow detection device 17 detects that the oil in the U-shaped tube 11 stops flowing, it means that the corresponding oil circuit of the U-shaped tube 11 is blocked. At this time, an alarm will be triggered. At the same time, the oil flow detection device 17 controls the oil pump 7 to stop running, waiting for the operator to repair the blocked oil circuit. After the repair is completed, the oil pump is started again to resume normal oil transmission. This avoids the blockage of the corresponding oil path of the U-tube 11, which causes the oil in the blower oil tank 601 to continue to increase, thereby causing a safety hazard.

[0049] A blower running-in flushing method comprises the following steps: Step (1): Close the valve 9 and add oil into the oil reservoir 1 through the oil filling port 102 on the oil reservoir 1. The oil exchange tank 14 is located inside the oil.

[0050] Step (2): start the oil purification device 2, the oil purification device 2 extracts the oil in the oil exchange tank 14 in the oil storage tank 1, and the oil enters the oil purification device 2 through the oil pipe 8. The oil purification device 2 purifies the gas, liquid and solid pollutants in the oil.

[0051] Since the oil filling port 102 and the oil exchange tank 14 are respectively located at two sides of the oil reservoir 1, when oil is added into the oil reservoir 1 through the oil filling port 102 on the oil reservoir 1, large particles of impurities in the oil will directly settle to the bottom of the oil reservoir 1 and will not enter the oil exchange tank 14. Therefore, it is possible to avoid large particles of impurities being mixed in the oil extracted by the oil purification device 2 and affecting the oil purification effect of the oil purification device 2.

[0052] Step (3): The purified oil enters the interior of the intermediate oil tank 3 through the oil outlet on the oil purification device 2, the oil pipe 8, and the oil inlet on the intermediate oil tank 3 in sequence, and then enters the interior of the closed oil tank 4 through the oil outlet on the intermediate oil tank 3 in sequence. Since the closed oil tank 4 adopts a closed structure, it can ensure that the oil is stored in the closed oil tank 4 for a long time and is not contaminated.

[0053] When there is too much oil in the intermediate oil tank 3 and the liquid level reaches the overflow port 301, it will flow back to the inside of the oil storage tank 1 through the overflow port 301, the oil pipe 8 and the first oil hole 101 in sequence, playing the role of automatic overflow oil reflux.

[0054] Step (4): The oil pump 7 draws the oil from the closed oil tank 4 and transmits the oil from the closed oil tank 4 to the blower oil tank 601 through the oil pipe 8. The blower 6 runs and the oil circulates inside the blower to run-in and flush the internal components of the blower 6.

[0055] Since an overflow oil receiving box 10 is provided on one side of the blower oil tank 601, and the blower oil tank 601 and the overflow oil receiving box 10 are balancedly connected via a U-shaped tube 11, the oil volume inside the blower oil tank 601 can be adjusted according to actual oil demand by adjusting the port height of the U-shaped tube 11 inside the overflow oil receiving box 10, and the oil height inside the blower oil tank 601 is made equal to the port height of the U-shaped tube 11 inside the overflow oil receiving box 10 through the U-shaped tube 11.

[0056] Step (5): The oil pump 7 continuously extracts the oil from the closed oil tank 4 and continuously transports the oil to the blower oil tank 601. When there is too much oil in the blower oil tank 601, the oil will overflow into the overflow oil storage box 10 through the U-shaped tube 11. Then, the oil in the overflow oil storage box 10 will flow back to the inside of the oil storage tank 1 through the oil pipe 8 and the oil filling port 102 in sequence. On the one hand, the effective circulation of the oil in the blower oil tank 601 is achieved. During the circulation process, the oil in the blower oil tank 601 after running-in and flushing can be filtered out. On the other hand, excessive oil in the blower oil tank 601 can be avoided to prevent safety hazards.

[0057] At the same time, part of the oil inside the closed oil tank 4 will enter the oil contamination detector 5 through the oil pipe 8. The oil contamination detector 5 detects the purification effect of the incoming oil and monitors the cleanliness of the purified oil in real time. The detected oil enters the middle oil tank 3 through the oil pipe 8 and the third oil hole 302 in turn.

[0058] Step (6): After the running-in and flushing are completed, the oil pump 7 is turned off, the valve 9 is opened, and the oil inside the blower oil tank 601 flows back to the inside of the oil storage tank 1 through the oil pipe 8 and the oil filling port 102 in sequence, completing the running-in and flushing process of the internal components of the blower 6.

[0059] The running-in and flushing device can be connected to multiple blowers 6 at the same time to perform running-in and flushing operations. An oil quantity control overflow device 15 and a valve 9 are respectively installed on one side of each blower 6. Each group of blowers 6 and the corresponding oil quantity control overflow device 15 and valve 9 are respectively connected in parallel between the oil outlet end of the oil pump 7 and the oil filling port 102 of the oil storage tank 1.

[0060] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope covered by the claims of the present invention.

The oil purification device purifies the gas, liquid and solid pollutants in the oil; Since the oil filling port and the oil exchange tank are located at two sides of the oil storage tank, when oil is added to the oil storage tank through the oil filling port on the oil storage tank, large particles of impurities in the oil will directly settle to the bottom of the oil storage tank, and will not enter the oil exchange tank. Therefore, it can be avoided that the oil extracted by the oil purification device is mixed with large particles of impurities, which will affect the oil purification effect of the oil purification device; Step (3): the purified oil enters the interior of the intermediate oil tank through the oil outlet on the oil purification device, the oil pipe, and the oil inlet on the intermediate oil tank in sequence, and then enters the interior of the closed oil tank through the oil outlet on the intermediate oil tank in sequence. Since the closed oil tank adopts a closed structure, it can ensure that the oil is stored in the closed oil tank for a long time and is not contaminated; When there is too much oil in the intermediate oil tank and the liquid level reaches the overflow port, it will flow back to the inside of the oil storage tank through the overflow port, the oil pipe, and the first oil hole in sequence, playing the role of automatic overflow oil return; Step (4): the oil pump extracts the oil in the closed oil tank and transmits the oil in the closed oil tank to the blower oil tank through the oil pipe. The blower runs and the oil circulates inside the blower to run-in and flush the internal components of the blower. Since an overflow oil receiving box is provided on one side of the blower oil tank, and the blower oil tank and the overflow oil receiving box are balancedly connected via a U-shaped tube, the oil volume inside the blower oil tank is adjusted by adjusting the port height of the U-shaped tube inside the overflow oil receiving box according to the actual oil volume demand, and the oil height inside the blower oil tank is made equal to the port height of the U-shaped tube inside the overflow oil receiving box via the U-shaped tube; Step (5): The oil pump continuously extracts the oil from the closed oil tank and continuously transports the oil to the blower oil tank. When there is too much oil in the blower oil tank, the oil will overflow into the overflow oil storage box through the U-shaped pipe. Then, the oil in the overflow oil storage box will flow back to the inside of the oil storage tank through the oil pipe and the oil filling port in sequence. On the one hand, the effective circulation of the oil in the blower oil tank is achieved. During the circulation process, the oil in the blower oil tank after running-in and flushing can be filtered out. On the other hand, excessive oil in the blower oil tank is avoided to prevent safety hazards. At the same time, part of the oil in the closed oil tank will enter the oil contamination detector through the oil pipe. The oil contamination detector will detect the purification effect of the incoming oil and monitor the cleanliness of the purified oil in real time. The tested oil will enter the middle oil tank through the oil pipe and the third oil hole in turn. Step (6): After the running-in and flushing are completed, the oil pump is turned off and the valve is opened. The oil inside the blower oil tank flows back to the oil reservoir through the oil pipe and the oil filling port in sequence, completing the running-in and flushing process of the internal components of the blower.
