How to make the refrigeration compressor routine maintenance method

1, often check in presence of clutter even motor conductive objects, coil has been damaged, the stator and the rotor for friction, otherwise the motor starts makes the motor burn out;

2, pay attention to the constant temperature and humidity test chamber compressor and its equipment and environmental health. The ash on the compressor condenser cleaning on a regular basis. Because too much dust accumulation will lead to overpressure or refrigeration equipment malfunction;

3, observing the fuselage of the oil level of oil pool and oiler whether lubricating oil is lower than the scale line foot (such as low should be timely Oil foot must stop check) ;

4, carefully check the constant temperature and humidity test chamber cylinder at all levels and the action of moving parts according to 'hear' sound to identify its working condition is normal, if found abnormal voice to stop the machine immediately to check;

5, the lubrication used confidential precipitation filtration. Compressor oil to use difference between winter and summer.

6, for water-cooled compressor if the water can't immediately to go into the water to avoid because of the uneven and cylinder cracks. After parking in winter to put away the place such as cooling water in order to avoid the cylinder frost crack; The compression of air cooling can be as long as the indoor temperature is not hot and cold, manufacturers suggest it is best to put in a standard laboratory, equipped with air conditioning, temperature can often period of constant temperature at 25 It is advisable to 28 degrees.

7, feel with the hand detection under high and low temperature alternating hot and humid test chamber cross rail in suction exhaust cutting cover the place such as the temperature is normal;

8, check whether the constant temperature and humidity test chamber cooling water temperature and flow rate is normal;

9, check whether the compressor vibration, with or without ground screw loose and fall off phenomenon;

10, pay attention to the constant temperature and humidity test chamber pressure gauge at all levels, storage tanks and the pressure gauge and oil pressure gauge on the cooler indicates whether the value within the prescribed scope;

11, check the constant temperature and humidity test chamber lubricating oil supply situation, mechanism of oil lubrication system ( Some compressor in containing organic glass plate on the side of the fuselage crosshead guide rail, can directly see the crosshead movement and supply situation of lube oil) ; Cylinders, packing available one-way cut oil drain to check, can check the oiler to oil in the cylinder;

12, pay attention to the rise of temperature of the motor, bearing temperature and voltage meter, ammeter indicates whether is normal, electric current shall not exceed the rated current of the motor, if more than, to find a reason or stop check;

13, electrical heating process whether there is a sound;

14, check the constant temperature and humidity test chamber pressure regulator or load regulator, security cutting is sensitive.

15, regular cleaning refrigeration system, especially the copper tube and bottle body. Regularly check the freon allowance.

16, storage tanks, coolers, oil water separator are often sent out.

It isn't just about being on air conditioner capacitor anymore–it's about maximizing the potential of the platform of manufacturing.
