[0002] The compressor oiler consists of an oil tank, a single pump and other components. It is a key auxiliary equipment for compressor packing and cylinder lubrication, and is also one of the key points of equipment maintenance.

[0003] After the compressor oiler unit pump has been used continuously for a period of time, a certain amount of oil stains will be deposited on the inner wall of the unit pump and the oil sight glass. Firstly, the oil stains on the inner wall of the oil sight glass affect the inspection personnel's observation of the lubrication condition of the packing and the cylinder, and it is also impossible to adjust the oil injection amount of the unit pump; secondly, there are impurities in the internal mechanism of the unit pump, which causes the unit pump to fail to work normally.

[0004] The existing treatment method is generally to disassemble it, soak it in kerosene, and clean it manually. The oiler single pump has a small and compact structure and is particularly easy to be damaged during the cleaning, disassembly and assembly process. The inside of the single pump is difficult to clean.

Through the automated design, the control device controls the time relay, and the oil circuit control valve and the air control valve are opened and closed according to the light transmittance data, so as to realize automatic cleaning.

[0040] like Figures 1 to 4 As shown, further, a waste liquid tank 1 is provided inside the box body 3, and the waste liquid tank 1 is located above the cleaning liquid storage tank 2. The top of the waste liquid tank 1 is connected to the multiple monomer pump clamping platforms 4. An 80-mesh stainless steel filter device is installed in the waste liquid tank 1. The bottom end of the waste liquid tank 1 is tilted, and the cleaning liquid storage tank 2 is provided with an oil inlet. The oil inlet of the cleaning liquid storage tank 2 is located at the bottom of the waste liquid tank 1, and the bottom of the cleaning liquid storage tank 2 is connected to a drain valve 7.

[0041] The beneficial effects of adopting the above further technical solution are: the 80-mesh stainless steel filter device is used to filter impurities in the waste liquid, so that the cleaning liquid can be recycled. The residual liquid generated after the compressor oiler monomer pump is cleaned is completely recovered through the waste liquid tank to ensure that the environment is not polluted.

The residual liquid generated after the compressor oiler monomer pump is cleaned is completely recovered through the waste liquid tank to ensure that the environment is not polluted. The oil inlet of the cleaning liquid storage tank is installed at the bottom of the waste liquid tank, which can be used to add new cleaning liquid and re-inject the filtered cleaning liquid into the cleaning liquid storage tank.

[0042] like Figures 1 to 4 As shown, further, the bottom end of the waste liquid tank 1 has an inclination angle of 20 degrees.

[0043] The beneficial effect of adopting the above further technical solution is that the cleaning liquid flows into the oil filling port smoothly, and the residual liquid generated after the compressor oiling device monomer pump is cleaned is completely recovered through the waste liquid tank to ensure that the environment is not polluted.

[0044] like Figures 1 to 4 As shown, further, the compressed air machine air valve 9 and the air automatic control valve 10 are connected to a compressed air pump through a pipeline, a time relay is provided in the control device 12, the control device 12 is a control device with a display, the monomer pump clamping platform 4 is a monomer pump clamping platform with a first pressure sensor, the cleaning liquid storage tank 2 is connected to a second pressure sensor, and the first pressure sensor, the monomer pump clamping platform 4 and the second pressure sensor are all connected to the control device 12.

[0045] The beneficial effect of adopting the above further technical solution is that the compressor oiler automatic cleaner pressurizes the liquid storage tank through the air pump, and the cleaning liquid is injected into the monomer pump. The impurities are flushed out of the monomer pump through the high-speed flushing of the cleaning liquid in the monomer pump, so as to realize the cleaning work in the monomer pump. After the flushing is completed, the oil filling circuit control valve is automatically closed, and the air circuit control valve is automatically opened at the same time, and the compressed air is flushed into the internal pipeline of the monomer pump for purging, so as to flush the residual cleaning liquid and impurities inside. Through the automation design, the control device controls the time relay, and the oil circuit and the air circuit are automatically switched by setting the working time of the oil circuit control valve and the air control valve, so as to realize automatic cleaning. A monomer pump clamping table with a pressure sensing function is used to automatically identify whether a monomer pump is installed through pressure, and the working state of the corresponding circuit is opened according to the identified result. The pressure sensor on the clamping table determines whether a monomer pump is installed, so as to facilitate the automatic opening and closing of the compressor oiler monomer pump automatic cleaner. The second pressure sensor is used to detect the pressure of the cleaning liquid storage tank and the air pipeline in real time. The display screen shows the transmittance, liquid tank pressure, air line pressure, support table pressure and cleaning results.

[0047] The beneficial effects of adopting the above further technical solution are: the stainless steel box improves the corrosion resistance and impact resistance of the cleaner. Kerosene facilitates the cleaning of impurities and improves the cleaning efficiency. The protective cover is used to prevent the splashing of the cleaning liquid and facilitate the observation of the working state of the cleaner. The protective cover has a self-locking function to prevent accidental opening during operation.

[0048] The cleaner (automatic cleaner for the single pump of a compressor oiler) consists of a cleaning liquid storage tank 2, a waste liquid tank 1, a portable air pump (compressed air pump), three single pump clamping tables 4 with pressure sensing functions (single pump clamping tables with first pressure sensors), three groups of high-precision transmittance detectors (transmittance detectors 13), three groups of cleaning nozzles (cleaner 5), protective covers (which can be PVC protective covers), control equipment 12, RTU pressure sensors (Remote Terminal Units, i.e., second pressure sensors), displays (the displays can be integrated with the control equipment), time relays, three electric control valves and a number of pipelines, and can synchronously clean the three single pumps of a single compressor oiler.

[0049] It should be noted that the number of each component can be but is not limited to the above number, and the user can choose according to actual needs.

[0050] The pressure sensor (first pressure sensor) on the clamping table (monomeric pump clamping table 4) determines whether a monomer pump is installed, and uses a high-precision transmittance detector (transmittance detector) to identify the oil stains in the oil window of the compressor monomer pump. According to the transmittance, it can be used as a working period of 5 minutes: the air pump (compressed air pump) is used to pressurize the liquid storage tank (cleaning liquid storage tank 2), and the cleaning liquid is forced into the monomer pump. The impurities are flushed out of the monomer pump by the high-speed flushing of the cleaning liquid in the monomer pump. The time can last for 4 minutes. After the flushing is completed, it is automatically switched to the air path, and the compressed air is flushed into the internal pipeline of the monomer pump for 1 minute to flush the residual cleaning liquid and impurities inside. The air path can be automatically closed after 1 minute. After a working period, the transmittance continues to be identified. If the transmittance does not reach 90%, the cleaning continues for the next 5-minute working period, and then the transmittance continues to be identified. After the transmittance reaches 90%, the power supply and oil circuit control valve of the compressed air pump are automatically closed, and the air continues to clean until the air pressure is 0.

[0052] Through automated design, the control device controls the time relay, and the oil circuit control valve and the air control valve are opened and closed through the transmittance data. By setting the working time of the oil circuit control valve (oil circuit automatic control valve) and the air control valve (air automatic control valve), automatic switching of the oil circuit and the air circuit is achieved, and automatic cleaning is realized.

[0053] The function of the RTU pressure sensor (second pressure sensor) is to perform real-time pressure detection on the cleaning fluid storage tank and air pipeline.

[0054] The display screen displays information including light transmittance, liquid tank (cleaning liquid tank) pressure, air line pressure, single pump clamping table pressure and cleaning results.

[0055] A single pump clamping table with a pressure sensing function is used to automatically identify whether a single pump is installed through pressure, and start the working state of the corresponding road according to the identification result.

[0056] The residual liquid generated after cleaning the compressor oiler unit pump is completely recovered through the waste liquid tank 1 to ensure that the environment is not polluted.

[0057] (1) The cleaning effect is improved by internal circulation of cleaning fluid and compressed air purging. After cleaning, the oil stain removal rate of the lubricator reaches 98%.

[0058] (2) Through experiments, it was found that the manual cleaning time for a group of three compressor oiler pumps was about 90 minutes; the longest cleaning time for a group of compressor oiler pumps using an automatic cleaner was 15 minutes, and the maintenance time was shortened by 83%.

[0061] 2. Equipment working mode: Use compressed air pump for pressurization. The equipment's compressed air pump uses a 220V external power supply. A compressed air pump with a 12V working voltage can also be used, but the working efficiency will be reduced.

[0062] 3. The cleaning fluid used in the equipment (compressor oiler single pump automatic cleaner) is kerosene.

[0063] 4. During the cleaning process, the cleaning liquid pressure is controlled at 0.4MPa and the air pressure is controlled at 0.4MPa.

[0064] 5. An 80-mesh stainless steel filter device is installed in the waste liquid tank to filter out impurities in the waste liquid and recycle the cleaning liquid.

[0065] 6. The bottom of the waste tank is designed with a slope of 20°. As long as there is a slope, the cleaning liquid will flow into the oil filling port.

[0066] 7. The oil inlet of the cleaning liquid storage tank is installed at the bottom of the waste liquid tank. It can be used to add new cleaning liquid or to re-inject the filtered cleaning liquid into the cleaning liquid storage tank.

[0067] 8. The protective cover is made of transparent PVC material to prevent splashing of cleaning liquid.

[0068] 9. The protective cover has a self-locking function to prevent accidental opening during work.

[0069] 10. The automatic cleaner of the compressor lubricator unit pump is equipped with an anti-leakage protection device.

After the flushing time is reached, the control device closes the oil circuit automatic control valve and the compressed air machine air inlet valve, and opens the air automatic control valve to perform air purge on the compressor lubricator unit pump; S4. After the air purge time is reached, the control device closes the air automatic control valve.

[0072] The beneficial effects of the technical solution of the present invention are: the cleaning fluid is automatically pumped into the monomer pump, and the impurities are flushed out of the monomer pump through the high-speed flushing of the cleaning fluid in the monomer pump, thereby achieving the cleaning work inside the monomer pump. After the flushing is completed, the oil filling circuit control valve is automatically closed, and the air circuit control valve is automatically opened at the same time, and compressed air is flushed into the internal pipeline of the monomer pump for purging, so as to flush out the residual cleaning fluid and impurities inside. Multiple monomer pumps of a single compressor oiler can be automatically and synchronously cleaned. The work of manually cleaning the monomer pump of the compressor oiler is solved, and the maintenance efficiency is improved; the problem of manual removal of impurities in the monomer pump of the compressor oiler is solved, and the cleaning time of the monomer pump of the compressor oiler is greatly shortened; the problem of frequent replacement of the new compressor oiler monomer pump due to improper manual cleaning of the compressor oiler monomer pump is solved, and the service life of the compressor oiler monomer pump is extended.

[0077] The beneficial effect of adopting the above further technical solution is: using a high-precision light transmittance detector to identify the oil stains in the oil sight glass of the compressor unit pump, and judging whether it is cleaned according to the light transmittance. After one working period, continue to identify the light transmittance. If the light transmittance does not reach 90%, continue to clean in the next 5-minute working period, and then continue to identify the light transmittance. After the light transmittance reaches 90%, the power supply of the compressed air pump and the oil circuit control valve are automatically turned off, and the air continues to be cleaned until the air pressure is 0. Through the automated design, the control device controls the time relay, and the oil circuit control valve and the air control valve are opened and closed through the light transmittance data, so as to realize automatic cleaning.

[0078] Further, step S1 includes: S11, a first pressure sensor on the monomer pump clamping platform detects whether there is a compressor oiler monomer pump installed on the monomer pump clamping platform; S12, when a compressor oiler monomer pump is installed on the monomer pump clamping platform, the control device obtains the flushing time and air purge time input by the user.

[0079] The beneficial effect of adopting the above further technical solution is: judging whether a monomer pump is installed by the pressure sensor on the clamping table, it is convenient to automatically open and close the compressor oiler monomer pump automatic cleaner.

[0080] like Figure 7As shown, start, 1. Install the compressor oiler to be cleaned; 2. Determine whether there is a single pump installed through the pressure sensor on the clamping table, and use a high-precision transmittance detector to identify the oil stains in the oil sight glass of the compressor single pump; 3. Clean and purge in a working period of 5 minutes; 31. If the transmittance does not reach 90%, continue to clean in the next 5-minute working period; 311. After the transmittance reaches 90%, the compressed air pump power supply and oil circuit control valve are automatically turned off, and the air continues to clean until the air pressure is 0. 3111. The air continues to purge until the pressure drops to 0, and enters step 4. 4. After the purge is completed, all control circuits are closed and the self-locking device is closed. Cleaning is completed.

[0081] After step 3, the following steps are included: 32. After the light transmittance reaches 90%, the power supply of the compressed air pump and the oil circuit control valve are automatically turned off; 321. The air continues to be purged until the pressure drops to 0, and then step 4 is entered.
