How to maintain the compressor in a constant temperature and humidity box well
　　
1. Carefully check the sound of the cylinders and moving parts at all levels to determine if their working condition is normal. If any abnormal sound is found, immediately stop the machine for inspection;
　　
2. Pay attention to whether the indicated values of pressure gauges at all levels, pressure gauges on gas storage tanks and coolers, and lubricating oil pressure gauges are within the specified range;
　　
3. Check if the cooling water temperature and flow rate are normal;
　　
4. Check the supply of lubricating oil and the lubrication system of the moving mechanism (some compressors are equipped with organic glass baffles on the side of the crosshead guide rail of the machine body, which can directly see the movement of the crosshead and the supply of lubricating oil); The cylinder and packing can be inspected for oil discharge using a one-way valve, which can check the condition of the oil injector injecting oil into the cylinder;
　　
5. Observe whether the oil level in the oil tank of the machine body and the lubricating oil in the oil injector are below the scale line. If they are low, they should be refilled in a timely manner (if using a dipstick, stop and check);
　　
6. Check the temperature of the intake and exhaust valve covers at the cross guide rail of the crankcase with your hand to see if it is normal;
　　
7. Pay attention to the temperature rise of the motor, bearing temperature, and whether the readings on the voltmeter and ammeter are normal. The current should not exceed the rated current of the motor. If it exceeds the rated current, the cause should be found or the machine should be stopped for inspection;
　　
8. Regularly check whether there are any debris or conductive objects inside the motor, whether the coil is damaged, and whether there is friction between the stator and rotor, otherwise the motor will burn out after starting;
　　
If it is a water-cooled compressor and water cannot be immediately supplied after cutting off the water supply, it is necessary to avoid cylinder cracks due to uneven heating and cooling After parking in winter, the cooling water should be drained to prevent the cylinder and other areas from freezing and cracking;
　　
10. Check whether the compressor vibrates and whether the foundation screws are loose or detached;
　　
11. Check whether the pressure regulator or load regulator, safety valve, etc. are sensitive;
　　
12. Pay attention to the hygiene of the compressor, its associated equipment, and the environment;
　　
13. Gas storage tanks, coolers, and oil-water separators should regularly release oil and water;
　　
14. The lubricating machine used should be precipitated and filtered. Compressor oil should be used differently in winter and summer.
