Industrial dehumidifier compressor stuck processing method

What does the compressor card cylinder of an industrial dehumidifier mean? in fact. The compressor card cylinder is that the shaft of the compressor is stuck, and the compressor cannot be rotated at this time.

The compressor of the industrial dehumidifier causes the card cylinder or the refrigeration oil does not come, so that the lubrication is insufficient, the friction is increased, or there is dust or impurities in the pipeline, causing the sports surface to be stuck, or the mechanical failure causes the compressor card to be stuck. dead.

Approach:

First, the tapping method

Generally choose a wooden hammer or select available objects in place. The hammer hits the three solder joints on the body when the press is started. But pay attention, you can't knock deformation. Gently tap the compressor casing to slightly loosen the stuck part, sometimes start the operation or increase the power supply voltage by 10%, and start the impact multiple times. This method can solve the problem of insufficient lubrication of the card cylinder. The compressor is particularly effective.

Second, the strong method

(1) Connect a plug, L is directly connected to the C terminal, N is connected to the M terminal, and the other is connected to the branch line N1, and the power is turned on to let the N1 touch the starting end S of the compressor;

(2) When the compressor is started, use the conductive end of the screwdriver to directly short the two ends of the starting capacitor, and the time is within 2S; (the hand must hold the insulated end)

If the high voltage impact can not solve the problem, the reason for the card cylinder is not caused by lack of oil, there may be mechanical or electrical failure, pay attention to safety when operating, beware of electric shock and shell, preferably standing on the rubber stool On or on dry wood/paper;

Third, the capacitor start method.

Increasing the capacitance is one of the most common methods. Simply put a capacitor on the original capacitor or a larger capacitor to increase the starting torque to make the compressor easier to run. Note: The compressor will shut down immediately after two or three seconds of startup.

Fourth, the pressure relief method (also known as decompression method)

Put some of Freon out to reduce the pressure, and then use the above method to make comprehensive use.

V. Pressure shock method

The compressor of the dehumidifier was separately removed, and a reaction force of 0.1 MPA was supplied to the compressor from the high pressure pipe with nitrogen. The loose shaft mechanism is loosened. Rinse for 5 minutes. Then use the above method.

Six-phase power supply start method

If the above does not work, the three-phase power supply start method can be used. The connection method is that the N connection C.R and S are connected to different phases of the live line. Plug in for a short time to start within 6 seconds.

Seven, lubrication method.

Usually, there is a scale inside the compressor of the dehumidifier, or a card cylinder caused by dirt, and the above does not work. The compressor is removed and the oil is poured out. Add kerosene, then pour it out, once in a row, the purpose is to clean the dirty things inside. After washing, put the compressor upside down for 12 hours, pour the kerosene and volatilize it. Then add No. 25 refrigerating oil, pick up the compressor and then a few times on the ground to loosen the parts. Then use the above method to start

After the repair is OK, you must add R22 refrigeration oil, the effect will be much better.

The above several methods can flexibly use many dehumidifier compressors, provided that the compressor resistance is normal.
