[0033] The present embodiment provides a compressor lubrication system for processing the lubricating oil in the compressor 100 and then allowing the lubricating oil to be recycled, thereby reducing the maintenance frequency of the compressor 100, reducing the labor intensity of the staff, increasing the service life of the compressor 100, reducing the consumption of lubricating oil, and reducing environmental pollution.

[0034] like Figure 1 As shown, the compressor lubrication system provided in this embodiment is arranged outside the compressor 100, and the compressor lubrication system includes an oil channel 1 for circulating lubricating oil, and the oil channel 1 has an oil outlet 11 connected to the oil filling port 108 of the compressor 100 and an oil inlet 12 connected to the oil discharge port 109 of the compressor 100. Exemplarily, the oil channel 1 can be formed by a pipeline or the like.

[0035] The compressor lubrication system also includes a cooling component 2, a gas-liquid separator 3, an oil filter 4 and an oil quality detection component 5, wherein the cooling component 2 is connected to the oil channel 1 and is used to cool the lubricating oil in the oil channel 1, so that the lubricating oil heated in the compressor 100 is cooled to a preset temperature, thereby preventing the lubricating oil from deteriorating due to excessively high temperature and preventing the lubricating oil from having too low a viscosity, thereby ensuring the lubricating effect of the lubricating oil and extending the service life of the lubricating oil.

[0036] The gas-liquid separator 3 is connected to the oil channel 1 and is used to separate the gas in the lubricating oil in the oil channel 1, that is, the gas-liquid separator 3 can separate the process gas in the lubricating oil, such as the process gas can be the impurity gas contained in the methyl chloride circulating gas, thereby preventing the process gas from deteriorating the lubricating oil.

[0037] The oil filter 4 is connected to the oil channel 1 and is used to filter impurities in the lubricating oil in the oil channel 1. For example, the impurities may be viscous substances such as solids, polymers and hydrolyzates, so as to further process the lubricating oil.

[0038] The oil quality detection component 5 is connected to the oil channel 1 and is located downstream of the cooling component 2, the gas-liquid separator 3 and the oil filter 4. The oil quality detection component 5 is used to detect whether the lubricating oil filtered by the oil filter 4 is qualified. The oil outlet end of the oil quality detection component 5 is selectively connected to the oil filter 4 and one of the oil outlets 11. Specifically, if the lubricating oil is qualified, the oil outlet end of the oil quality detection component 5 is connected to the oil outlet 11 to allow the lubricating oil to circulate back to the compressor 100. If the lubricating oil is unqualified, the oil outlet end of the oil quality detection component 5 is connected to the oil filter 4 so that the lubricating oil can return to the oil filter 4 of the compressor lubrication system for filtration again.

[0039] The cooling component 2, the gas-liquid separator 3 and the oil filter 4 complete the processing of the lubricating oil, including the processing of impurities and the control of temperature. Then, the oil quality detection component 5 determines whether the lubricating oil after filtering by the oil filter 4 is qualified. If the lubricating oil is qualified, it can be circulated back to the compressor 100. If the lubricating oil is unqualified, the lubricating oil can be returned to the oil filter 4 of the compressor lubrication system for filtration again. If the lubricating oil detection value continues to decrease, or the oil control quality continues to remain at a low level, the oil filter 4 can be inspected or replaced to ensure that the lubricating oil entering the compressor is qualified. In the utility model, when the lubricating oil is unqualified, there is no need to inspect and clean a single compressor one by one, thereby reducing a large amount of tedious and repetitive maintenance work. And because the lubricating oil quality is controllable, the service life of the compressor is greatly improved, the consumption of wearing parts is reduced, and economic value is created.

[0040] The compressor lubrication system can be used on the existing compressor 100 without modifying the structure of the compressor 100, thus avoiding incurring additional costs.

[0041] By adding an external compressor lubrication system, the deterioration of the lubricating oil in the compressor 100 caused by process gas, impurities and high temperature is eliminated, the quality of the lubricating oil entering the compressor 100 is guaranteed, and the replacement of wearing parts is reduced while ensuring the lubrication effect between the internal components of the compressor 100, the maintenance frequency is reduced, the service life of the compressor 100 is increased, the consumption of compressor wearing parts and lubricating oil products is minimized, the economic efficiency is improved, and the safe operation of the compressor 100 is guaranteed.

[0042] After using the compressor lubrication system, (a) the original daily switching inspection is changed to inspection and adjustment of the compressor 100 every shift (8 hours), and the compressor 100 can be inspected and repaired according to the oil pressure difference obtained from the inspection, thereby reducing the frequency of inspections and greatly reducing labor intensity; (b) the compressor 100 valve, cylinder 101, piston 106, intake valve group, etc. can be inspected and repaired according to the compression effect, thereby reducing the number of inspections and replacements of wearing parts; (c) the frequency of lubricating oil replacement is reduced, and the consumption of lubricating oil products is minimized. Originally, 4 compressors 100 consumed 200 kilograms of lubricating oil every day. After using the compressor lubrication system, the oil consumption of 4 compressors 100 is reduced to about 50 kilograms per day; (d) the economic efficiency of equipment operation and the inherent safety level of compressor 100 operation are improved.

[0043] Optionally, the cooling assembly 2 may include a cold water tank and a cooling coil, wherein cooling water flows in the cold water tank, and the cooling coil is disposed in the cold water tank, and the cooling coil can increase the heat exchange area and improve the cooling effect. The cooling assembly 2 may also be other structures as long as it can cool the lubricating oil.

[0044] Optionally, the gas-liquid separator 3 further includes an oil collector 6, and the cooling assembly 2, the oil collector 6, and the gas-liquid separator 3 are arranged in sequence from the upstream side to the downstream side, so that the lubricating oil cooled by the cooling assembly 2 is concentrated and enters the gas-liquid separator 3, thereby improving the separation effect of the gas-liquid separator 3. The oil collector 6 is in the prior art, so its specific structure is not described in detail.

[0045] Optionally, the cooling component 2, the oil collector 6, the gas-liquid separator 3, the oil filter 4 and the oil detection component 5 are arranged in sequence from the upstream side to the downstream side, that is, the lubricating oil is first cooled, and then subjected to gas-liquid separation and impurity removal. After the lubricating oil is cooled, the effect of gas-liquid separation and impurity removal can be further improved.

[0046] Exemplarily, the compressor lubrication system further includes an oil pump 10, which is connected to the oil channel 1 and is used to drive the lubricating oil to flow in the oil channel 1. The oil pump 10 can increase the circulation speed of the lubricating oil between the compressor 100 and the compressor lubrication system, and improve the processing efficiency of the lubricating oil. Further, the oil pump 10 can be located downstream of the cooling assembly 2, and more specifically, the oil pump 10 is located between the cooling assembly 2 and the oil collector 6.

[0047] There may be multiple oil filters 4 , and the lubricating oil in the oil channel 1 passes through the multiple oil filters 4 in sequence, thereby performing multi-stage filtration on the lubricating oil.

[0048] Optionally, in order to make the oil outlet of the oil detection component 5 selectively communicate with one of the oil filter 4 and the oil outlet 11, the compressor lubrication system may further include a first branch 7 and a first control valve for controlling the on-off of the first branch 7, the first branch 7 includes a first inlet end and a first outlet end both connected to the oil channel 1, the first inlet end is located downstream of the oil detection component 5, and the first outlet end is located upstream of the gas-liquid separator 3 and the oil filter 4, further, the first inlet end is connected to the outlet of the oil detection component 5, and the first outlet end is located between the gas-liquid separator 3 and the oil pump 10. A channel control valve is connected to the oil channel 1 between the oil detection component 5 and the oil outlet 11, and the channel control valve is used to control the on-off of the oil channel 1.

[0049] When the oil quality detection component 5 detects that the lubricating oil is unqualified, the channel control valve is closed, the first control valve is opened, and the lubricating oil flows back to the oil channel 1 at the downstream of the gas-liquid separator 3 and the oil filter 4. The lubricating oil flows in the oil channel 1, and the gas-liquid separator 3 and the oil filter 4 can process the lubricating oil again. When the oil quality detection component 5 detects that the lubricating oil is qualified, the channel control valve is opened, the first control valve is closed, and the lubricating oil enters the compressor 100 from the oil outlet 11, thereby ensuring that the lubricating oil entering the compressor 100 is qualified.

[0050] Optionally, the compressor lubrication system may further include a controller, which is electrically connected to the oil detection component 5, the channel control valve and the first control valve. The oil detection component 5 transmits the detected data to the controller, and the controller controls the on and off of the channel control valve and the first control valve according to the detected data, thereby realizing oil control. The channel control valve and the first control valve may be solenoid valves. The controller may be a centralized or distributed controller, for example, the controller may be a single single-chip microcomputer, or may be composed of multiple distributed single-chip microcomputers, and a control program may be run in the single-chip microcomputer to control the above-mentioned components to realize their functions.

[0051] Optionally, the oil product detection component 5 includes at least one of a particle size detector, a viscosity detector, and a pH detector. The viscosity detector is used to detect the viscosity of the lubricating oil, the pH detector is used to detect the pH of the lubricating oil, and the particle size detector is used to detect the particle content in the lubricating oil, to help the staff to correctly analyze the contamination of the lubricating oil and timely judge the working condition of the mechanical parts. The oil product detection component 5 can also include an alarm unit, which is electrically connected to the particle size detector, the viscosity detector, and the pH detector respectively. When the data detected by the particle size detector, the viscosity detector, and the pH detector are unqualified, the alarm unit can sound an alarm, such as an alarm through an indicator light or a sound, to prompt the staff in time.

[0052] Optionally, the oil quality detection component 5 may also include an oil quantity detection component, which is used to detect the oil quantity. For example, the oil quantity detection component detects the amount of oil flowing in the oil channel 1 over a period of time. If the oil quantity in the oil channel 1 is too low over a period of time, it means that the amount of oil entering the compressor 100 is insufficient.

[0053] In order to provide a sufficient amount of lubricating oil to the compressor 100, optionally, the compressor lubrication system further includes an oil tank 8 for storing new oil, a second branch 9, and a second control valve for controlling the on-off of the second branch 9. The second branch 9 includes a second outlet end connected to the oil channel 1 and a second inlet end connected to the oil tank 8. The second outlet end is located upstream of the oil quality detection component 5. Specifically, the second outlet end is connected to the inlet of the oil quality detection component 5. When the oil quality detection component 5 detects that the amount of oil is insufficient, or at a preset interval, the oil tank 8 replenishes a sufficient amount of lubricating oil to the oil channel 1 through the second branch 9, thereby ensuring that a sufficient amount of lubricating oil is provided to the compressor 100. Since the second outlet end is located upstream of the oil quality detection component 5, the oil quality detection component 5 can detect whether the oil quality and / or oil amount of the lubricating oil provided by the oil tank 8 is qualified.

[0054] Optionally, the second control valve is electrically connected to the controller, so that the on and off of the second control valve is controlled by the controller.

[0055] The oil channel 1 includes multiple groups of oil outlets 11 and oil inlets 12, and each group of oil outlets 11 and oil inlets 12 can be connected to a compressor 100. Multiple compressors 100 share a compressor lubrication system, which can improve the utilization rate of the compressor lubrication system, reduce the total volume of the equipment, and reduce the total cost. For example, Figure 1 As shown, the compressor lubrication system has three groups of oil outlets 11 and oil inlets 12, which can provide lubricating oil for three compressors 100, and the three compressors 100 are arranged in parallel.

[0056] like Figure 2 As shown, the compressor 100 provided in the embodiment is an existing compressor 100, which may include a cylinder body 101, a crankshaft oil pump 102 and a built-in cooler 103. The cylinder body 101 has an oil storage space 11, the crankshaft oil pump 102 and the built-in cooler 103 are both arranged in the oil storage space 11, the oil filling port 108 and the oil discharge port 109 are both connected to the oil storage space 11, and the oil discharge port 109 is preferably located at the bottom of the oil storage space 11, and the lubricating oil level in the oil storage space 11 is not lower than the inlet of the crankshaft oil pump 102, and the crankshaft oil pump 102 can drive the lubricating oil to flow. The built-in cooler 103 is connected to the cylinder body 101 and is located at the lower side of the crankshaft oil pump 102 to cool the lubricating oil in the oil storage space 11, reduce the temperature of the compressor 100, and reduce energy consumption. Optionally, the built-in cooler 103 can be a built-in cooling coil, and a coolant can be circulated in the built-in cooling coil, so as to cool the lubricating oil in the oil storage space 11.

[0057] Exemplarily, the compressor 100 may further include a crankshaft 104, a connecting rod 105, and a piston 106. The crankshaft 104, the connecting rod 105, and the piston 106 are all disposed in the cylinder body 101. The crankshaft 104 is connected to the connecting rod 105. The connecting rod 105 is driven to perform linear motion by the rotation of the crankshaft 104. The connecting rod 105 is connected to the piston 106, so that the piston 106 slides in the piston cylinder of the cylinder body 101, thereby compressing the gas such as methyl chloride. The crankshaft 104 and the connecting rod 105 are hollow structures, and lubricating oil can enter the crankshaft 104 and the connecting rod 105.

[0058] The oil outlet of the crankshaft oil pump 102 can be connected to the oil inlet hole on the crankshaft 104, and the lubricating oil enters the crankshaft 104, the connecting rod 105, and the bearing 107 connected to the crankshaft 104 through the crankshaft oil pump 102, thereby lubricating the connecting rod 105, the crankshaft 104, and the bearing 107. When the crankshaft 104 rotates, the crank of the crankshaft 104 can splash the lubricating oil, and the splashed lubricating oil lubricates the piston ring, the piston 106, the valve plate, etc. After the lubricating oil is collected with the process gas, it is processed by the external compressor lubrication system and then recycled.

[0059] In other optional embodiments, the structure of the compressor 100 is not limited thereto, and as long as it needs lubricating oil, it can be connected to the compressor lubrication system provided in this embodiment by having an oil filling port 108 and an oil outlet 11 .

[0060] like Figure 1 As shown, this embodiment also provides a compressor lubricating oil processing method, and the compressor lubricating system mentioned above can be used to execute the compressor 100 lubricating oil processing method, and the compressor lubricating oil processing method includes:

[0061] Connect the compressor lubrication system outside the compressor 100, and connect the oil filling port 108 of the compressor 100 to the oil outlet port 11 of the compressor lubrication system, and connect the oil discharge port 109 of the compressor 100 to the oil inlet port 12 of the compressor lubrication system;

[0062] The lubricating oil in the compressor 100 enters the compressor lubrication system for processing through the oil inlet 12. If the lubricating oil after processing does not meet the standards, it will continue to be processed in the compressor lubrication system. If the lubricating oil after processing meets the standards, it will be injected into the oil filling port 108 through the oil outlet 11.

[0063] The compressor lubricating oil processing method provided in this embodiment can provide qualified lubricating oil for the compressor 100, thereby reducing the maintenance frequency of the compressor 100, reducing the labor intensity of the staff, increasing the service life of the compressor 100, reducing the consumption of lubricating oil and wearing parts, and reducing environmental pollution.

[0064] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model.
