Compressor cylinder is stuck compressor shaft is stuck, the compressor can not rotate at this time. The reason that the compressor causes the cylinder to jam is either the frozen oil does not come up, so that the lubrication is insufficient, the friction increases, or the pipe has the dust, the impurity, causes the moving surface to jam, or the pure mechanical breakdown causes the compressor to jam.

Treatment method of compressor cylinder jam

 The percussive method

 Choose a wooden hammer or select the available items in place. When the press starts, the hammer hits the three welds on the body. But pay attention to the force. Don't break the shape. Gently tap the compressor casing to loosen the stuck part, sometimes it can start operation or increase the power supply voltage by 10% , multiple start-up shock, this method can solve the problem of not enough lubrication stuck cylinder, especially effective for rotary compressors.

Two, strong up method

Connect a plug, l directly connected to the C terminal, N connected to the M terminal, another out of the branch line N1, turn on the power so that N1 touch the starting end of the compressor S.

Capacitance starting method

 Increasing the capacity is one of the most common methods, simply put on the original capacitor and a capacitor or change a larger capacitor, to increase the starting Torque to make the compressor easier to operate. Note: The compressor started two or three seconds immediately shut down.

 Pressure relief method also known as decompression method

 Release some of the Freon to reduce the pressure, and then use the above methods, comprehensive utilization.

Pneumatic shock method

Remove the compressor from the high pressure pipe and use nitrogen to give the compressor a 0.1 MPA reaction. Make hold the axle parts loose. Five minutes of air. Then apply the above methods.

Three-phase power start method

Above all do not work, can use three-phase power start method, connect method is n to connect C. R and s are connected to different firing lines. Plug-in short time to start within 6 seconds.

 Lubrication method

Usually the compressor internal oxide skin, or dirt caused by the card cylinder, the above can not work, the compressor removed, the oil out. Add Kerosene, and then pour it out again, one time, the goal is to wash out the dirty things inside, clean and then put the compressor upside down for 12 hours, the kerosene, and volatile. Then add 25 frozen oil, pick up the compressor and then in the ground pier a few times, so that the machine loose. Before using the above method to activate.

   Repair Ok to add R22 frozen oil, the effect will be much better. The above methods are flexible use of a lot of compressors can be repaired, if the compressor resistance is normal.
