The characteristics of piston compressor

1, high reliability

2, the cooling effect of high.

3, low noise, low exhaust pulse.

4, the precision machining parts and components to ensure efficient operation of the compressor.

5, good cooling reduces stress generated to extend the life of the machine.

6, a special valve design to ensure that the tolerance of the compressor capacity hit high.

7, the built-in safety devices ensure that the reliable operation of the compressor.

8, broad operating conditions; widely applied to frozen, refrigerated display case, automatic selling machines, commercial refrigerators, refrigerator, dehumidifiers, low temperature test equipment, as well as special low-temperature equipment.

Completely closed refrigeration compressor piston attention

1, the compressor removal process should be maintained-home, light caving, tilt angle not greater than 45 °.

2, the compressor and the ground level should remain vertical, the largest installation tilt angle is less than 5 °.

3, compressor factory before adequate refrigeration oil injection, the use of not arbitrarily add and also not arbitrarily increase other brands of frozen oil, or they may cause operational failure.

4, compressor refrigeration system installed in the former and not to suction and exhaust outlets, rubber Cypriots out in the process. Access System should be within 10 minutes assembly, welding, so as not to enter the water in the air compressor and refrigeration system to produce the harm.

4, oil / refrigerant than the recommended weight for 0.4 and above (oil proportion 0.92).

5, refrigerant from the condenser refrigeration system into the tail end, and not directly into the compressor.

6, when the compressor in the vacuum will not be high voltage test or launch test.

7, should not try to start without the compressor package actuating devices.

8, in order to avoid the problem started in the pre-commencement for the first time in 10 ° C above the compressor environment.

9, in the compressor are not allowed to use antifreeze, antifreeze will be damaged because such a concentrated material used. Antifreeze in particular that the content of ethanol and methanol synthesis of motor insulation destructive role.

10, installed in the cooling system of compressors, refrigeration agent in charge after 15 minutes, the compressor must be running 20 seconds more. Have to start again after the shutdown intervals three minutes more.

Specifications:low noise ,high reliability,low vibration,high efficiency
Export Markets:millde east; south america;africa
various compressors is used for air-conditioner as a replacement parts ,and they are high quality and excellent matching.
