Refrigerant compressor cylinder card?

compressor cylinder is the compressor rotor stuck, the compressor can't turn. Compressor on the causes of card cylinder or frozen oil, increase the insufficient lubrication, friction, or line with dust, impurities, cause movement face stuck, stuck or purely mechanical failure causes compressor.

a, tapping method

in choosing wooden hammer or on-site choices available items. When press to start the heavy hammer knock them three solder joints. But should pay attention to the strength, can't knock out of shape. Gently tap the compressor shell, vibration stuck part slightly loose, sometimes can start running or 10% higher than the supply voltage to raise, start the impact for many times, this method can solve the card cylinder insufficient lubrication, especially effective for rotary compressor.

2, strong up

( 1) Connect a plug, L directly on C, N M side, the other from the N1, let N1 by tapping the compressor start turning on the power supply side S.

3, capacitor start

increasing capacitance is one of the most common method, simply put on the original capacitor and a capacitor, or in a larger capacitance, to increase the starting torque for compressor are more likely to work. Note: the compressor started off as soon as two or three seconds.

4, pressure relief method ( Also known as the decompression method) Freon

put off something, to reduce the pressure, and then to use the above method, the comprehensive utilization.

5, impact pressure method

removed, compressor separately from the high pressure pipe with nitrogen gas to the compressor a 0. Reaction of 1 mpa. The holding shaft parts a bit. Air flushing for 5 minutes. Then using the above method.

6, three-phase power supply startup method

if the above doesn't work available three-phase power supply startup method, connection is N C. R and S are connect the wire of different phase. Plug in the short time to start within 6 seconds.

7, lubrication

usually have scale, compressor internal cause card cylinder or dirt, the can't work, the compressor to be removed, the oil poured out. Join the kerosene, and then poured out, continuous time, purpose is to wash the dirty things inside out, put the compressor horse 12 hours after washing clean, poured kerosene net, and evaporate. Frozen oil, then add the 25th again picked up the compressor block a few times on the ground, to loosen parts. Then start to use the above method.

after the repair OK to join the R22, frozen oil, the effect will be much better. The above several methods flexibly apply many of the compressor can be repaired, the premise is the compressor normal resistance.

The increasing consumption demand in key segments such as start capacitor suppliers, start capacitor suppliers and start capacitor suppliers have been driving the sales of and its derivatives worldwide.
