The maintenance of air compressor is simple and simple, but it is also quite complicated. The air compressor is not complicated in terms of structure. There are more than ten or twenty large and small parts in total, but I want to understand each part. The connection between them requires a lot of experience. For a simple example, there are several possibilities for the air compressor to fail to start normally. If you don't understand it enough, you may only learn one or two reasons from books, and you can't solve the problems caused by other reasons. Today, the editor will bring you some knowledge about air compressor repair and maintenance, and hope that it will bring you some help in future operations.
1. Answer and deal with the relevant questions based on the crew's feedback on the recent operation of the machine;
2. Check whether the air compressor system has leaks, air leaks, or oil leaks, and shut down for maintenance if necessary;
3. Check whether the automatic drains of the air compressor, air storage barrel, dryer, and filter are draining normally, visually check whether the discharged water is in a normal state, and if there is clogging or flying oil, deal with the relevant parts;
4. Inspection records of ambient temperature, ventilation and heat dissipation, and suggestions for improvement if necessary;
5. Exhaust pressure inspection records; adjust the pressure switch and regulator valve when necessary, and check and repair the system when abnormal;
6. Examination record of exhaust temperature, clean the radiator when necessary;
7. Check the record of running hours, confirm the usage hours of consumables, and propose a regular replacement plan for consumables;
8. Check the temperature at the outlet of the compressor head, check the temperature control components and clean the radiator when necessary.
9. Oil tank pressure inspection record, adjust the minimum pressure valve and replace when necessary.
10. Check the pressure difference of the oil and gas separator and the oil separator; check and repair the system when abnormal, and replace it regularly.
11. Check the condition of the air filter and clean it; replace it if necessary.
12. Regular inspection of oil level and oil quality; add and replace when necessary.
13. The inspection records of the drive belt couplings should be adjusted and replaced regularly; in case of sudden abnormalities, timely adjustments should be made and restored;
14. Inspection and cleaning of oil circuit system (the quality of air compressor lubricating oil is very important);
15. Check the noise and vibration of compressor body and motor operation; provide written solutions and suggestions when abnormal, and implement them;
16. Cooling water pressure, inlet temperature, record; check the original and deal with it when abnormal;
17. Check and record the surface temperature and current of the motor; check the original and deal with it when it is abnormal;
18. External power supply voltage inspection record;
19. Visually inspect the electrical contacts, wire contacts, and surface insulation of the distribution box; if necessary, polish the contacts to test;
20. Clean up the machine platform and pump room;
21. Check the evaporation and condensation pressure of the dryer; adjust and clean the radiator when needed, troubleshooting;
22. Carry out the necessary maintenance and repair work according to the situation at the time of the inspection, fill out the work sheet after each work is completed, sign the order to the person in charge on site and make corresponding answers.
