What is Compressor and How to Protect it Well

The compressor is a kind of flowing fluid machine that promote low pressure air to the high pressure air. It is the heart of refrigeration ,which it inhals refrigeration air of low temperature and low pressure from air suction pipe, then the valve compresses it by dynamo’ working. It discharges refrigeration air of high temperature and high pressure to exhaust pipe , which provide power for refrigeration calculation , so finish the refrigeration calculation from compression to condensation to inflation to evaporation .

Compressor is the heart of cube ice machine and other ice machines refrigeration system. The compressor protection is of a great importance .Now I will show you some malfunctions of compressor and solve them with you.

It includes two parts .On the one hand , It is the compressor overload that has four cases.

Back to the liquid too much, load compressor, and it heats. I think you should adjust the expansion valve to reduce back to liquid.

1.Compressor temperature control module damaged. Check the compressor is overheating,

2.automatically reset after the motor cooled. Or change compressor temperature module.

3. Less refrigerant oil causes the compressor to heat. To increase the refrigerant oil.

4. Environmental temperature is high, compressor current is too large. Check the overload reason, press FR1 the reset key.

On the other hand ,it is the compressor fault. It includes three big parts. One of them is Crankshaft parts.

1.Connecting rod wear cause space. You can adjust the clearance. If not ok ,you can adjust the expansion to ensure suction the gas refrigerant.

2.Valve or other matters breaking and dropping into the cylinder. Repair and adjust the space.

3 Too much lubricating oil cause oil hit. Remove the matters and repair the breaking parts.

4 Liquid refrigerant cause liquid hit. Check the lubricating oil system to make it get normal, release excess oil.

The second is about Loose parts.

1.Connecting rod bolt and nut are loose. Review and adjust the space.

2.Compressor bottom studs loosed. Tighten the nuts.

3.Oil pump gear wheel weared and loosed. Tighten all the bolts on the bottom studs.

The last one but important one is that Compressor cannot start or start to stop.

1.Power Circuit Fault. Check and repair the electric circuit.

2.Compressor jammed vat closed. Check and repair the jammed part, remove the fault.

3.Temperature control adjust inappropriate. Correctly adjust the temperature controller ,or replace it if necessary.

4.External power has no power. Check it whether disconnect power, and connect power.

5.ZK1、ZK2 power switch tripping. Manual reset.

6.The press of the system control panel button or switch can’t work. Check and change the corresponding button or switch.

All the possible malfunctions of compressor are shown above .
