[0003] The present application relates to the running-in of a device, in particular to a running-in flushing method. BACKGROUND
[0005] The main types of blowers include Roots blowers and screw blowers, which have the characteristics of small volume, light weight, low noise, stable operation, etc., and are suitable for gas transportation and pressure increase in various processes, such as water treatment, chemical industry, metallurgy, etc.
[0006] After the production and manufacturing of the blower are completed, the transmission components inside the blower need to be running-in flushed. The existing running-in flushing method is to extract the engine oil in the oil storage tank by an oil pump and inject it into the inside of the blower to running-in flush the internal components.
[0007] However, the engine oil in the existing oil storage tank is contaminated to varying degrees due to long-term storage, and during use, the engine oil is not effectively purified. The gaseous, liquid, and solid three-state pollutants in the oil entering the inside of the blower will cause serious damage to the gears, bearings, seals, and other components or hydraulic components such as pump valves in the hydraulic system, especially the gas in the oil will cause cavitation, damage the surface of the transmission components, produce particulate pollutants, further contaminate the oil, and ultimately affect the service life and sealing reliability of the blower. SUMMARY
[0009] The present application provides a running-in flushing method that can effectively purify the oil in the oil storage tank, improve the cleanliness of the engine oil, and use the purified engine oil to running-in flush the inside of the blower, which can avoid damage to the gears, bearings, seals, and other components or hydraulic components such as pump valves in the hydraulic system, improve the service life and sealing reliability of the blower. And by installing an oil pollution detector in the detection oil circuit, the purified engine oil can be detected in real time, the real-time monitoring of the engine oil purification effect is realized, and further security is brought to the safety of the blower test run.
[0010] Therefore, the technical solution of the present application is a running-in flushing method, which includes a running-in flushing device, and the running-in flushing method includes the following steps: Step (1): Close the valve, add oil to the inside of the oil tank through the oil inlet on the oil tank, and the oil exchange tank is located inside the oil; Step (2): Start the oil purification device, and the oil purification device extracts the oil inside the oil exchange tank in the oil tank, and the oil is introduced 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 inlet and the oil exchange tank are located on both sides of the inside of the oil tank, when oil is added to the inside of the oil tank through the oil inlet on the oil tank, large particles in the oil will directly precipitate to the bottom of the oil tank, and will not enter the inside of the oil exchange tank. Therefore, the oil extracted by the oil purification device is not mixed with large particles, which affects the oil purification effect of the oil purification device; Step (3): The purified oil enters the inside 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 turn, and then enters the inside of the closed oil tank through the oil outlet on the intermediate oil tank.

The height of the oil in the blower tank is equal to the height of the port of the U-shaped pipe in the overflow oil storage box through the U-shaped pipe; Step (5): The oil pump continuously extracts the oil in the closed oil tank and continuously delivers the oil to the inside of the blower tank. When the oil in the blower tank is too much, the oil will overflow to the overflow oil storage box through the U-shaped pipe. Then, the oil in the overflow oil storage box flows back to the inside of the oil tank through the oil pipe and the oil inlet, on the one hand, realizing the effective circulation of the oil in the blower tank, and on the other hand, avoiding the excessive oil in the blower tank and the safety hazard; Meanwhile, part of the oil in the closed oil tank enters the oil contamination detector through the oil pipe, the oil contamination detector detects the purification effect of the entering oil, monitors the cleanliness of the purified oil in real time, and the detected oil enters the intermediate oil tank through the oil pipe and the third oil hole in turn.

[0024] The present invention will be further described below with reference to embodiments.
[0025] pass Figures 1-7 It can be seen that the break-in flushing device is equipped with an oil storage tank 1, an oil purification device 2, an intermediate oil tank 3, an oil pump 7, and an oil quantity control overflow device 15.
[0026] The oil purification device 2 is located on one side of the oil storage tank 1. An oil pipe 8 is provided between the oil inlet of the oil purification device 2 and the oil outlet of the oil storage tank 1. The oil purification device 2 draws oil from the inside of the oil storage tank 1 through the oil pipe 8.
[0027] An oil pipe 8 is provided between the oil outlet of the oil purification device 2 and the oil inlet of the intermediate oil tank 3. The oil outlet of the oil purification device 2 and the oil inlet of the intermediate oil tank 3 are connected through the oil pipe 8 to realize the transfer of oil.
[0028] An oil pipe 8 is provided between the oil outlet of the intermediate oil tank 3 and the oil inlet of the oil pump 7. The oil outlet of the intermediate oil tank 3 and the oil inlet of the oil pump 7 are connected through the oil pipe 8 to realize the transmission of oil.
[0029] A blower 6 is provided on one side of the oil outlet of the oil pump 7. The blower 6 is equipped with a blower oil tank 601. The oil outlet of the oil pump 7 is connected to the oil inlet of the blower oil tank 601 to realize the transmission of oil.
[0030] The top end of the oil storage pool 1 is provided with an oil inlet 102, which is in communication with the inside of the oil storage pool 1. The oil outlet of the air blower oil tank 601 is provided with an oil pipe 8, which is in communication with the oil inlet 102.
[0031] The oil amount control overflow device 15 is located on one side of the air blower oil tank 601. The oil amount control overflow device 15 is used to adjust the oil amount in the air blower oil tank 601, so that the oil amount in the air blower oil tank 601 can be maintained at a set amount.
[0032] Through the oil amount control overflow device 15, the oil amount in the air blower oil tank 601 can be adjusted, and the oil amount in the air blower oil tank 601 can be controlled to maintain a set amount, so that the air blower oil tank 601 does not have too much oil, which can cause safety hazards.
[0033] At the same time, the effective circulation of the oil in the air blower oil tank 601 can be realized. During the circulation process, the oil in the air blower oil tank 601 after the running-in flushing can be filtered out, so that clean oil with high cleanliness can be continuously used in the air blower oil tank 601, and the running-in flushing effect of the internal components of the air blower 6 can be improved.
[0034] The inside of the oil storage pool 1 is provided with an oil exchange groove 14, which is fixedly connected to one side of the inside of the oil storage pool 1. One end of the oil pipe 8 on the oil outlet of the oil storage pool 1 is located inside the oil exchange groove 14 near the lower end position.
[0035] The oil inlet of the intermediate oil tank 3 is located at the upper end of the intermediate oil tank 3. The oil outlet of the intermediate oil tank 3 is located at the lower end of the intermediate oil tank 3. The intermediate oil tank 3 is provided with an overflow port 301 near the upper end. 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, which is in communication with the inside of the oil storage pool 1. The other end of the overflow port 301 is provided with an oil pipe 8, which is in communication with the first oil hole 101.
[0036] Through the setting of the overflow port 301, the effective safety protection effect can be achieved. Specifically, when the oil in the intermediate oil tank 3 is too much and reaches the height of the overflow port 301, the oil will flow back to the oil storage pool 1 through the overflow port 301, which can avoid the oil in the intermediate oil tank 3 from leaking outwards, causing waste and pollution of the environment, or even causing the intermediate oil tank 3 to have too much pressure and causing greater safety hazards. In addition, through the backflow of the overflow port 301, the backflow oil can be purified again, further improving the purification degree of the oil.
[0037] The oil outlet side of the intermediate oil tank 3 is provided with a closed oil tank 4, the oil outlet of the intermediate oil tank 3 is communicated with the oil inlet of the closed oil tank 4, and the oil outlet of the closed oil tank 4 is communicated with the oil inlet of the oil pump 7. 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 without being contaminated. In addition, since the closed oil tank 4 has a certain pressure, when the oil pump 7 extracts the oil in the closed oil tank 4, it plays a role of auxiliary transmission outward, thereby reducing the operating load of the oil pump 7, ensuring the smoothness of oil transmission, and prolonging the service life of the oil pump 7.
[0038] 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 near the upper end position, the third oil hole 302 is communicated with the inside of the intermediate oil tank 3, the oil inlet of the pressure relief valve 402 is communicated 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 is communicated with the third oil hole 302 through the oil pipe 8. By arranging the pressure relief valve 402, when the pressure in the closed oil tank 4 is too large, the oil will flow back through the pressure relief valve 402 to avoid safety hazards. At the same time of pressure relief, the oil will flow back to the inside of the intermediate oil tank 3 through the oil pipe 8, avoiding the oil flowing to the outside environment caused by pressure relief, causing oil waste and pollution.
[0039] The oil outlet side of the closed oil tank 4 is provided with an oil pollution degree detector 5, the oil outlet of the closed oil tank 4 is communicated with the oil inlet of the oil pollution degree detector 5, and the oil outlet of the oil pollution degree detector 5 is communicated with the third oil hole 302.
[0040] The oil pollution degree detector 5 can effectively detect the purified oil, and monitor the cleanliness of the purified oil in real time, further ensuring the safety and reliability of the air blower running-in flushing. 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, avoiding oil waste.
[0041] The oil amount control overflow device 15 includes an overflow oil storage box 10, which is located at the lateral side of the air blower oil tank 601.
[0042] The lower end position of the overflow oil storage box 10 is provided with a fifth oil hole 1002, which is communicated with the inside of the overflow oil storage box 10.
[0043] The oil outlet of the air blower oil tank 601 is communicated with the fifth oil hole 1002 through a U-shaped tube 11. One end of the U-shaped tube 11 is communicated with the oil outlet of the air blower oil tank 601, and the other end of the U-shaped tube 11 extends to the inside of the overflow oil liquid storage box 10 through the fifth oil hole 1002. The port position of the U-shaped tube 11 in the inside of the overflow oil liquid storage box 10 is within the height range of the inside of the air blower oil tank 601. According to the actual oil quantity requirement, the port height of the U-shaped tube 11 in the inside of the overflow oil liquid storage box 10 is adjusted to adjust the oil quantity in the inside of the air blower oil tank 601, so that the oil liquid height in the inside of the air blower oil tank 601 is equal to the port height of the U-shaped tube 11 in the inside of the overflow oil liquid storage box 10.
[0044] The lower end position of the overflow oil liquid 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 liquid 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.
[0045] When the oil liquid in the air blower oil tank 601 is excessive, the oil liquid will overflow to the overflow oil liquid storage box 10 through the U-shaped tube 11, and then the oil liquid in the overflow oil liquid storage box 10 will flow back to the inside of the oil storage pool 1 in sequence through the oil pipe 8 and the oil inlet 102. On the one hand, the effective circulation of the oil liquid in the air blower oil tank 601 is realized, and the oil liquid in the air blower oil tank 601 after the running-in flushing can be filtered out in the circulation process. On the other hand, the excessive oil liquid in the air blower oil tank 601 is avoided, and the safety hidden danger is avoided.
[0046] The oil outlet side of the air blower oil tank 601 is provided with a valve 9. One end of the valve 9 is communicated with the oil outlet of the air blower oil tank 601, and the other end of the valve 9 is communicated with the oil inlet 102 through the oil pipe 8. In the process of running-in flushing of the air blower, the valve 9 is in a closed state to ensure the normal operation of the running-in flushing. When the running-in flushing of the air blower is completed, the valve 9 is opened, and the oil liquid in the inside of the air blower oil tank 601 flows back to the inside of the oil storage pool 1 in sequence through the oil pipe 8 and the oil inlet 102, and the running-in flushing process of the internal components of the air blower 6 is completed. In addition, the valve 9 also plays the role of an emergency switch. When a fault occurs, the oil liquid in the air blower oil tank 601 can be actively discharged by opening the valve 9 to avoid safety hidden danger.
[0047] The upper end position of the overflow oil liquid storage box 10 is provided with an air vent 1003. One end of the air vent 1003 is communicated with the inside of the overflow oil liquid storage box 10, and the other end of the air vent 1003 is provided with a gas pressure balance pipe 13. The gas pressure balance pipe 13 is communicated with the air vent 1003, and the other end of the gas pressure balance pipe 13 is communicated with the outside atmosphere. The inside of the overflow oil liquid storage box 10 is communicated with the outside atmosphere through the gas pressure balance pipe 13, which can ensure that the action of the oil quantity control overflow device 15 is maintained effectively.
[0048] The oil inlet 102 at the top end of the oil storage pool 1 is located on the side away from the oil liquid exchange groove 14. When the backflowing oil liquid 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 on the two sides of the oil storage pool 1 respectively, the impurities in the backflowing oil liquid can be prevented from falling into the inside of the oil liquid exchange groove 14, further ensuring the cleanliness of the oil liquid in the oil liquid exchange groove 14, and avoiding that the particulate impurities in the backflowing oil liquid fall into the oil liquid exchange groove 14, which affects the oil cleaning effect of the oil cleaning device 2 when the oil cleaning device 2 extracts the oil liquid mixed with impurities.
[0049] The air blower oil tank 601 is provided with an overflow hole 16 near the upper end. One end of the overflow hole 16 is in communication 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 is in communication with the overflow hole 16, and the other end of the overflow pipe 12 is in communication with the air vent 1003. When the oil liquid 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 liquid will flow to the inside of the overflow oil liquid storage box 10 through the overflow hole 16, the overflow pipe 12 and the air 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, to complete the entire overflow process, thereby avoiding damage to the air blower due to too much oil liquid in the air blower oil tank 601.
[0050] The U-shaped pipe 11 is provided with an oil liquid flow detection device 17. Since the entire running-in flushing process requires the oil pump 7 to continuously transmit oil liquid to the air blower oil tank 601, the oil liquid in the air blower oil tank 601 continuously flows to the inside of the overflow oil liquid storage box 10 through the U-shaped pipe 11 by the communication principle of the U-shaped pipe 11. Therefore, during the running-in flushing process, a continuous oil liquid flow is formed in the U-shaped pipe 11, and the oil liquid flow in the U-shaped pipe 11 is monitored in real time by the oil liquid flow detection device 17. The oil liquid flow detection device 17 is provided with an alarm. When the oil liquid flow detection device 17 detects that the oil liquid in the U-shaped pipe 11 stops flowing, 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 by the oil liquid flow detection device 17. After the operating personnel repair the blocked oil passage, the oil pump is started again to restore normal transmission of oil liquid. In this way, the continuous increase of the oil liquid 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 avoided.
[0051] The running-in flushing method of the running-in flushing device described above includes the following steps: Step (1): Close the valve 9, and add oil liquid to the inside of the oil storage pool 1 through the oil inlet 102 on the oil storage pool 1. The oil liquid exchange groove 14 is located in the inside of the oil liquid.
[0052] Step (2): Start the oil purifying device 2, the oil purifying device 2 extracts the oil in the oil exchange tank 14 in the oil storage pool 1, and the oil is introduced into the oil purifying device 2 through the oil pipe 8, and the oil purifying device 2 purifies the gas, liquid and solid pollutants in the oil.
[0053] Since the oil inlet 102 and the oil exchange tank 14 are located at two positions on the inside of the oil storage pool 1, when the oil is added to 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 precipitate to the bottom of the oil storage pool 1, and will not enter the inside of the oil exchange tank 14, so that the oil extracted by the oil purifying device 2 is not mixed with large particle impurities, and the oil purifying effect of the oil purifying device 2 is affected.
[0054] Step (3): The purified oil enters the inside of the intermediate oil tank 3 through the oil outlet of the oil purifying device 2, the oil pipe 8 and the oil inlet of the intermediate oil tank 3 in sequence, and then enters the inside of the closed oil tank 4 through the oil outlet of the intermediate oil tank 3 in sequence. 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 without being contaminated.
[0055] When the oil in the intermediate oil tank 3 is too much and the liquid level reaches the overflow port 301 position, it will flow 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 in sequence, and play the role of automatic overflow.
[0056] 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 air blower oil tank 601 through the oil pipe 8. The air blower 6 runs, and the oil is circulated in the inside of the air blower to lubricate and flush the internal components of the air blower 6.
[0057] Since the overflow oil storage box 10 is arranged on one side of the air blower oil tank 601, and the air blower oil tank 601 and the overflow oil storage box 10 are balancedly communicated through the U-shaped pipe 11, according to the actual oil quantity demand, the oil quantity in the air blower oil tank 601 is adjusted by adjusting the port height of the U-shaped pipe 11 in the overflow oil storage box 10, and the oil height in the air blower oil tank 601 is equal to the port height of the U-shaped pipe 11 in the overflow oil storage box 10 through the U-shaped pipe 11.
[0058] Step (5): the oil pump 7 continuously extracts the oil in the closed oil tank 4, and continuously delivers the oil to the inside of the air blower oil tank 601. When the oil in the air blower oil tank 601 is too much, the oil will overflow through the U-shaped pipe 11 to the overflow oil storage box 10, 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. On the one hand, it realizes the effective circulation of the oil in the air blower oil tank 601, and during the circulation process, it can filter out the oil in the air blower oil tank 601 after the running-in flushing, on the other hand, it avoids the safety hidden trouble caused by too much oil in the air blower oil tank 601.
[0059] At the same time, part of the oil in the closed oil tank 4 will enter the inside of the oil pollution detector 5 through the oil pipe 8. The oil pollution 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.
[0060] Step (6): after the running-in flushing is completed, the oil pump 7 is closed, and the valve 9 is opened. 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 and the oil inlet 102, and the running-in flushing process of the internal components of the air blower 6 is completed.
[0061] The running-in flushing device can simultaneously connect multiple air blowers 6 for running-in flushing operation. One side of each air blower 6 is respectively provided with an oil amount control overflow device 15 and a valve 9. Each group of air 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.
[0062] The above is only a specific embodiment of the present application, which cannot limit the scope of the present application. The replacement of equivalent components or equivalent changes and modifications made within the scope of the present application should still be within the scope of the claims of the present application.
Claims
1. A break-in flushing method, characterized in that: The break-in and flushing device is included, and the break-in and flushing method includes the following steps: Step (1): Close the valve and add oil into the oil storage tank through the oil inlet on the oil storage tank. The oil exchange tank is located inside the oil storage tank. Step (2): Start the oil purification device. The oil purification device draws the oil from the oil storage tank located inside the oil exchange tank and puts 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 inlet and the oil exchange tank are located on opposite sides inside the oil storage tank, when oil is added into the oil storage tank through the oil inlet, 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 avoid the oil extracted by the oil purification device from being mixed with large particles of impurities, which would 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, oil pipe and oil inlet of the intermediate oil tank in sequence. Then it enters the interior of the closed oil tank through the oil outlet of the intermediate oil tank in sequence. Since the closed oil tank adopts a closed structure, there is a certain pressure inside the closed oil tank, which 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 level reaches the overflow port, it will flow back into the oil storage tank through the overflow port, oil pipe and first oil hole in sequence, thus playing the role of automatic overflow and return. Step (4): The oil pump draws oil from the closed oil tank and transfers the oil from the closed oil tank to the blower oil tank through the oil pipe. The blower runs and circulates the oil inside the blower to run-in and clean the internal components of the blower. Because the blower oil tank has an overflow oil collection box on one side, and the blower oil tank and the overflow oil collection box are connected by a U-shaped tube, the oil volume inside the blower oil tank can be adjusted by adjusting the height of the U-shaped tube inside the overflow oil collection box according to the actual oil volume requirement. The oil height inside the blower oil tank is made equal to the height of the U-shaped tube inside the overflow oil collection box through the U-shaped tube. Step (5): The oil pump continuously draws oil from the closed oil tank and continuously delivers oil to the blower oil tank. When there is too much oil in the blower oil tank, the oil will overflow through the U-shaped pipe into the overflow oil collection box. Then, the oil in the overflow oil collection box flows back to the inside of the oil storage tank through the oil pipe and the oil inlet. On the one hand, it realizes the effective circulation of oil in the blower oil tank. During the circulation process, it can filter out the oil after the break-in and flushing in the blower oil tank. On the other hand, it avoids the safety hazards caused by too much oil in the blower oil tank. Meanwhile, some of the oil inside the closed oil tank will enter the oil contamination detector through the oil pipe. The oil contamination detector will test the purification effect of the oil and monitor the cleanliness of the purified oil in real time. The tested oil will then enter the middle oil tank through the oil pipe and the third oil hole. Step (6): After the break-in and flushing are completed, turn off the oil pump and open the valve. The oil inside the blower oil tank flows back to the inside of the oil storage tank through the oil pipe and the oil inlet in sequence, completing one break-in and flushing process of the internal components of the blower.
