Tape constant temperature and humidity test chamber cryogenic compressor maintenance method

After the user purchases a constant temperature and humidity tester for the tape, it will be used as a compressor for the core components of the constant temperature and humidity tester for the tape for a long period of time. How can you care for his beauty and make the life of the compressor longer and more efficient? Below, Haida Instrument will explain the maintenance methods and maintenance of refrigeration compressors for constant temperature and humidity test chambers.
1. Seriously inspect the movement sounds of cylinders and moving parts at all levels to determine whether it is working properly according to “ listening ” , and stop the inspection if abnormal sound is found ;

2. Pay attention to the pressure gauges of various stages of the compressor, the pressure gauges on the gas tanks and chillers, and the indication values ​​of the oil pressure gauges within the specified range ;

3 , check the temperature and humidity of the constant temperature and humidity test chamber cooling water, flow is normal ;

4. Observe whether the oil level in the oil sump of the fuselage and the oil in the oil injector are lower than the tick mark. If it is low, increase the amount of oil in time (use the dipstick to stop and check) ;

5 , touch the body to check the fuselage crankcase cross guide at the suction and exhaust cutting cover, etc., temperature is normal ;

6. Check the lubrication oil supply condition, the lubrication system of the moving mechanism, and some oil supply conditions (some compressors are equipped with plexiglass baffles on the side of the crosshead rail of the fuselage, and you can see the crosshead movement and the supply of lubricating oil directly) ; One-way cutting can be used as filling and filling inspection, and it can be used to inspect the oil filling device to the cylinder .

7 , the use of lubrication machine precipitation filter. Compressor oil in winter and summer should be used differently.

8 , check the pressure regulator or load regulator , safe cutting, etc. is sensitive ;

9. Check whether the compressor is vibrating, whether the anchor bolts are loose and fall off .

10. Pay attention to the hygiene of the constant temperature and humidity test chamber compressor and its associated equipment and environment ;

11 , gas tanks, coolers, oil and water separators should always release the oil and water.

12. Pay attention to the temperature rise of the motor, the bearing temperature and voltmeter, and the indication of the current meter is normal. The current must not exceed the rated current of the motor. If it exceeds, check the cause or stop the machine .

13. Always inspect the motor for foreign matter and even conductive objects. Whether the coil is damaged or not, and whether the stator or rotor has friction, otherwise the motor will be burned out after the motor starts ;

14 , if the water-cooled compressor can not immediately enter the water if water is cut off to avoid cylinder cracks due to uneven cooling and heating . After parking in winter to let go of cooling water to avoid cracking cylinders and other places.
