Description

[0001] This application is a divisional application of the patent application filed on October 28, 2024, with application number 2024115061957 and invention title "Blower Break-in and Flushing Device". Technical Field

[0003] This invention relates to the break-in process of equipment, and more particularly to a break-in flushing device. Background Technology

[0005] The main types of blowers include Roots blowers and screw blowers. They are characterized by small size, light weight, low noise, and stable operation, and are suitable for gas transportation and pressurization in various processes, such as water treatment, chemical industry, metallurgy and other industrial fields.

[0006] After the blower is manufactured, the internal transmission components need to be run-in and flushed. The existing method is to use an oil pump to draw oil from the oil reservoir and inject it into the blower to run in and flush the internal components.

[0007] However, the oil in existing oil storage tanks becomes contaminated to varying degrees due to prolonged storage. Furthermore, the oil is not effectively purified during use. When contaminated oil enters the blower, the gaseous, liquid, and solid contaminants in the oil can cause serious damage to components such as gears, bearings, and seals, as well as hydraulic components such as pumps and valves in the hydraulic system. In particular, the gas in the oil causes cavitation, which damages the surface of transmission components and generates particulate contaminants, further contaminating the oil and ultimately affecting the service life of the blower and the reliability of the seals. Summary of the Invention

[0009] To address the above-mentioned technical problems, this invention provides a break-in flushing device. Using this device, the oil in the oil storage tank can be effectively purified, improving the cleanliness of the oil. Using the purified oil to perform break-in flushing on the inside of the blower can prevent gas, liquid, and solid contaminants in the oil from damaging gears, bearings, seals, or hydraulic components such as pumps and valves in the hydraulic system, thereby improving the service life of the blower and the reliability of the seals. Furthermore, by installing an oil contamination detector in the oil circuit, the purified engine oil can be tested in real time, enabling real-time monitoring of the oil purification effect and providing further assurance for the safety of blower test runs.

An oil pipe is provided between the other end of the overflow port and the first oil hole. The overflow port and the first oil hole are connected through the oil pipe. An oil contamination detector is installed on one side of the oil outlet of the closed oil tank. The oil outlet of the closed oil tank is connected to the oil inlet of the oil contamination detector, and the oil outlet of the oil contamination detector is connected to the third oil hole. The oil quantity control overflow device includes an overflow oil collection box, which is located on one side of the blower oil tank. The bottom of the overflow oil collection box is provided with a fifth oil hole, which is connected to the interior of the overflow oil collection box; A U-shaped tube is installed 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 through the fifth oil hole to the inside of the overflow oil collection box. The position of the port of the U-shaped tube inside the overflow oil collection box is within the height range of the blower oil tank.

[0011] Preferably, the oil inlet at the top of the oil storage tank is located on the side away from the oil exchange tank.

[0012] The beneficial effects of this invention are: 1. Because an overflow oil collection box is provided on one side of the blower oil tank, and 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 into the interior of the overflow oil collection box through the fifth oil hole. The port of the U-shaped tube inside the overflow oil collection box is located within the height range of the blower oil tank. According to the actual oil volume requirement, the height of the port of the U-shaped tube inside the overflow oil collection box is adjusted to adjust the oil volume inside the blower oil tank, so that the oil height inside the blower oil tank is equal to the height of the port of the U-shaped tube inside the overflow oil collection box. Furthermore, since a fourth oil hole is provided at the lower end of the overflow oil collection box, one end of the fourth oil hole is connected to the interior of the overflow oil collection box, and the other end of the fourth oil hole is connected to the oil filling port through an oil pipe. 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 will flow back into the oil storage tank through the oil pipe and the oil inlet. On the one hand, this achieves effective circulation of the oil in the blower oil tank. During the circulation process, the oil after the break-in and flushing in the blower oil tank can be filtered out. On the other hand, it avoids the safety hazards caused by too much oil in the blower oil tank.

[0013] 2. By installing a closed-loop oil tank between the intermediate oil tank and the oil pump, the closed-loop oil tank, with its sealed structure, ensures that the oil is stored inside for a long time without being contaminated. Furthermore, because the closed-loop oil tank has a certain pressure, it plays a role in auxiliary transmission when the oil pump draws oil from the closed-loop oil tank, thereby reducing the operating load of the oil pump, ensuring smooth oil transmission, and improving the service life of the oil pump.

[0014] 3. By installing an oil contamination detector at the oil outlet of the closed oil tank, the purified oil can be effectively tested and its cleanliness can be monitored in real time, providing further assurance for the safety and reliability of the blower's break-in and flushing. The tested oil enters the interior of the intermediate oil tank through the oil pipe and the third oil hole in sequence, avoiding oil waste. Attached Figure Description

[0019] The present invention will be further described below with reference to embodiments.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] An oil inlet 102 is provided at the top of the oil storage tank 1. The oil inlet 102 is connected to the interior of the oil storage tank 1. An oil pipe 8 is provided between the oil outlet of the blower oil tank 601 and the oil inlet 102. The oil outlet of the blower oil tank 601 and the oil inlet 102 are connected through the oil pipe 8.

[0026] The oil quantity control overflow device 15 is located on one side of the blower oil tank 601. The oil quantity control overflow device 15 is used to adjust the oil quantity inside the blower oil tank 601 so that the oil quantity inside the blower oil tank 601 is continuously maintained at the set oil quantity.

[0027] The oil level control overflow device 15 can adjust the oil level inside the blower oil tank 601 and control the oil level inside the blower oil tank 601 to maintain the set oil level, so as to avoid excessive oil in the blower oil tank 601 and potential safety hazards.

[0028] At the same time, it can achieve effective circulation of oil in the blower oil tank 601. During the circulation process, it can filter out the oil in the blower oil tank 601 after break-in and flushing, ensuring that the blower oil tank 601 continuously uses oil with high cleanliness, and improving the break-in and flushing effect on the internal components of the blower 6.

[0029] The oil storage tank 1 is equipped with an oil exchange tank 14 inside. The oil exchange tank 14 is fixedly connected to one side wall of the oil storage tank 1. One end of the oil pipe 8 on the oil outlet of the oil storage tank 1 is located inside the oil exchange tank 14 near the lower end.

[0030] The oil inlet of the intermediate oil tank 3 is located at the upper end of the intermediate oil tank 3, and the oil outlet of the intermediate oil tank 3 is located at the lower end of the intermediate oil tank 3. An overflow port 301 is provided near the upper end of the intermediate oil tank 3. One end of the overflow port 301 is connected to the interior of the intermediate oil tank 3. A first oil hole 101 is provided at the top of the oil storage tank 1. The first oil hole 101 is connected to the interior of the oil storage tank 1. An oil pipe 8 is provided between the other end of the overflow port 301 and the first oil hole 101. The overflow port 301 and the first oil hole 101 are connected through the oil pipe 8.

[0031] By setting the overflow port 301, an effective safety protection function 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 tank 1 through the overflow port 301. This can prevent the oil in the intermediate oil tank 3 from being too much, which would lead to oil leakage, waste, and environmental pollution. In addition, when the oil in the intermediate oil tank 3 is too much, the pressure inside the intermediate oil tank 3 may become too high, resulting in greater safety hazards. Furthermore, the backflow through the overflow port 301 can purify the backflowed oil again, further improving the purification level of the oil.

[0032] A closed oil tank 4 is provided on one side of the oil outlet of the intermediate oil tank 3. The oil outlet of the intermediate oil tank 3 is connected to the oil inlet of the closed oil tank 4, and the oil outlet of the closed oil tank 4 is connected to the oil inlet of the oil pump 7. Since the closed oil tank 4 adopts a closed structure, it can ensure that the oil is stored inside 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 draws the oil from the closed oil tank 4, it plays a role in auxiliary transmission to the outside, thereby reducing the operating load of the oil pump 7, ensuring the smoothness of oil transmission, and improving the service life of the oil pump 7.

[0033] A pressure relief valve 402 is provided at the upper end of the closed oil tank 4, and a third oil hole 302 is provided near the upper end of the intermediate oil tank 3. The third oil hole 302 is connected to the interior of the intermediate oil tank 3. The oil inlet of the pressure relief valve 402 is connected to the interior of the closed oil tank 4. An oil pipe 8 is provided between the oil outlet of the pressure relief valve 402 and the third oil hole 302. The oil outlet of the pressure relief valve 402 and the third oil hole 302 are connected through the oil pipe 8. By setting the pressure relief valve 402, when the pressure inside the closed oil tank 4 is too high, the oil will be depressurized and flow back through the pressure relief valve 402 to avoid safety hazards. At the same time as depressurization, the oil will flow back to the interior of the intermediate oil tank 3 through the oil pipe 8 to prevent the oil generated by depressurization from flowing into the external environment, causing oil waste and pollution.

[0034] An oil contamination detector 5 is installed on one side of the oil outlet of the closed oil tank 4. The oil outlet of the closed oil tank 4 is connected to the oil inlet of the oil contamination detector 5, and the oil outlet of the oil contamination detector 5 is connected to the third oil hole 302.

[0035] The oil contamination detector 5 can effectively detect the purified oil and monitor its cleanliness in real time, providing further assurance for the safety and reliability of the blower's break-in and flushing. The tested oil enters the intermediate oil tank 3 through the oil pipe 8 and the third oil hole 302 in sequence, avoiding oil waste.

[0036] The oil quantity control overflow device 15 includes an overflow oil collection box 10, which is located on one side of the blower oil tank 601.

[0037] The lower end of the overflow oil collection box 10 is provided with a fifth oil hole 1002, which is connected to the interior of the overflow oil collection box 10.

[0038] 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 through the fifth oil hole 1002 into the interior of the overflow oil collection box 10. The port of the U-shaped tube 11 inside the overflow oil collection box 10 is located within the height range inside the blower oil tank 601. According to the actual oil volume requirement, the height of the port of the U-shaped tube 11 inside the overflow oil collection 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 height of the port of the U-shaped tube 11 inside the overflow oil collection box 10.

[0039] The lower end of the overflow oil collection box 10 is provided with a fourth oil hole 1001. One end of the fourth oil hole 1001 is connected to the interior of the overflow oil collection box 10, and the other end of the fourth oil hole 1001 is connected to the oil inlet 102 through the oil pipe 8.

[0040] When there is too much oil in the blower oil tank 601, the oil will overflow through the U-shaped pipe 11 into the overflow oil collection box 10. Then, the oil in the overflow oil collection box 10 will flow back into the oil storage tank 1 through the oil pipe 8 and the oil inlet 102. On the one hand, this achieves effective circulation of the oil in the blower oil tank 601. During the circulation process, the oil after the break-in and flushing in the blower oil tank 601 can be filtered out. On the other hand, it avoids the safety hazards caused by excessive oil in the blower oil tank 601.

[0041] 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 inlet 102 through the oil pipe 8. During the blower break-in and flushing process, the valve 9 is in the closed state to ensure the normal operation of the break-in and flushing. After the blower break-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 inlet 102 in sequence, completing one break-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 malfunction occurs and the oil in the blower oil tank 601 is too much, the oil in the blower oil tank 601 can be actively discharged by opening the valve 9 to avoid safety hazards.

[0042] The upper end of the overflow oil collection box 10 is provided with a vent 1003. One end of the vent 1003 is connected to the interior of the overflow oil collection box 10, and the other end of the vent 1003 is provided with a pressure balance pipe 13. The pressure balance pipe 13 is connected to the vent 1003, and the other end of the pressure balance pipe 13 is connected to the outside atmosphere. By connecting the interior of the overflow oil collection box 10 with the outside atmosphere through the pressure balance pipe 13, the function of the oil quantity control overflow device 15 can be maintained effectively.

[0043] The oil inlet 102 at the top of the oil storage tank 1 is located away from the oil exchange tank 14. When the returned oil flows back into the oil storage tank 1 through the oil inlet 102, since the oil inlet 102 and the oil exchange tank 14 are located on opposite sides of the oil storage tank 1, impurities in the returned oil can be prevented from falling into the oil exchange tank 14. This further ensures the cleanliness of the oil in the oil exchange tank 14 and prevents particulate impurities from falling into the oil exchange tank 14. When the oil purification device 2 extracts oil mixed with impurities, it will affect the oil purification effect of the oil purification device 2.

[0044] The blower oil tank 601 is provided with an overflow hole 16 near the upper end. One end of the overflow hole 16 is connected to the interior of the 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 connected to the overflow hole 16, and the other end of the overflow pipe 12 is connected to the vent 1003. When the oil in the blower oil tank 601 is too much due to a malfunction and reaches the overflow hole 16, the oil will flow through the overflow hole 16, the overflow pipe 12, and the vent 1003 to the interior of the overflow oil collection box 10 in sequence. Then, it will enter the interior of the oil storage tank 1 in sequence through the fourth oil hole 1001, the oil pipe 8, and the oil filling port 102, completing the entire overflow process and avoiding damage to the blower due to excessive oil in the blower oil tank 601.

[0045] The U-shaped tube 11 is equipped with an oil flow detection device 17. During the entire break-in and flushing process, the oil pump 7 needs to continuously transfer 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 collection box 10. Therefore, during the break-in and flushing process, a continuous oil flow will be formed in the U-shaped tube 11. The oil flow detection device 17 monitors the oil flow in the U-shaped tube 11 in real time. The oil flow detection device 17 is equipped with an alarm. When the oil flow detection device 17 detects that the oil in the U-shaped tube 11 has stopped flowing, it means that the corresponding oil passage of the U-shaped tube 11 is blocked. At this time, the alarm will be triggered. At the same time, the oil flow detection device 17 controls the oil pump 7 to stop running. After the operator repairs the blocked oil passage, the oil pump is restarted to restore normal oil transfer. This avoids the risk of a continuous increase in oil in the blower oil tank 601 due to blockage of the corresponding oil passage in the U-shaped pipe 11, which could cause safety hazards.

[0046] The break-in and flushing method of the above-mentioned break-in and flushing device includes the following steps: Step (1): Close valve 9 and add oil into oil storage tank 1 through oil inlet 102. Oil exchange tank 14 is located inside the oil storage tank.

[0047] Step (2): Start the oil purification device 2. The oil purification device 2 extracts the oil from the oil storage tank 1 located inside the oil exchange tank 14 and puts the oil into 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.

[0048] Since the oil inlet 102 and the oil exchange tank 14 are located on opposite sides inside the oil storage tank 1, when oil is added into the oil storage tank 1 through the oil inlet 102, large particles of impurities in the oil will directly settle to the bottom of the oil storage tank 1 and will not enter the oil exchange tank 14. Therefore, it can avoid the oil extracted by the oil purification device 2 from being mixed with large particles of impurities, which would affect the oil purification effect of the oil purification device 2.

[0049] 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. Then, it 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.

[0050] When there is too much oil inside the intermediate oil tank 3 and the oil level reaches the overflow port 301, it will flow back into the oil storage tank 1 through the overflow port 301, oil pipe 8 and first oil hole 101 in sequence, thus playing the role of automatic overflow and return.

[0051] Step (4): The oil pump 7 draws 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 circulates the oil inside the blower to run-in and clean the internal components of the blower 6.

[0052] Since the blower oil tank 601 is provided with an overflow oil collection box 10 on one side, and the blower oil tank 601 and the overflow oil collection box 10 are connected in a balanced manner through a U-shaped tube 11, the oil volume inside the blower oil tank 601 can be adjusted by adjusting the height of the port of the U-shaped tube 11 inside the overflow oil collection box 10 according to the actual oil volume requirement. The oil height inside the blower oil tank 601 is made equal to the height of the port of the U-shaped tube 11 inside the overflow oil collection box 10 through the U-shaped tube 11.

[0053] Step (5): The oil pump 7 continuously draws oil from the closed oil tank 4 and continuously delivers the oil to the blower oil tank 601. When there is too much oil in the blower oil tank 601, the oil will overflow through the U-shaped pipe 11 into the overflow oil collection box 10. Then, the oil in the overflow oil collection box 10 flows back to the inside of the oil storage tank 1 through the oil pipe 8 and the oil inlet 102. On the one hand, the oil in the blower oil tank 601 is effectively circulated. During the circulation process, the oil after the break-in and flushing in the blower oil tank 601 can be filtered out. On the other hand, the oil in the blower oil tank 601 is not too much and there is a safety hazard.

[0054] Meanwhile, some 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 will test the purification effect of the oil entering and monitor the cleanliness of the purified oil in real time. The tested oil will then enter the intermediate oil tank 3 through the oil pipe 8 and the third oil hole 302.

[0055] Step (6): After the break-in and flushing are completed, turn off the oil pump 7 and open the valve 9. 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 inlet 102 in sequence, completing one break-in and flushing process of the internal components of the blower 6.

[0056] This break-in flushing device can connect multiple blowers 6 simultaneously for break-in flushing operations. Each blower 6 is equipped with an oil quantity control overflow device 15 and a valve 9 on one side. Each set of blowers 6 and the corresponding oil quantity control overflow device 15 and valve 9 are connected in parallel between the oil outlet of the oil pump 7 and the oil inlet 102 of the oil storage tank 1.

[0057] However, the above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of the present invention should still fall within the scope of the claims of the present invention.
