What are the symptoms of snowflake ice machine compressor failure

The snowflake ice machine has been noticed by laboratory research in the encirclement of various block ice machines and flake ice machines. The reason is that the ice is finely crushed, can penetrate into narrow gaps, and has a high degree of fit with ice bath test tubes. To make such snowflake ice, the compressor contributes a lot. Inhalation, compression, exhaust, condensation, and throttling are all taken care of by the compressor. If the compressor fails to make ice, do you know what are the symptoms of a snowflake ice machine compressor failure? Will you judge?

Next, the manufacturer will tell you about the failure performance of the snowflake ice machine compressor:
Symptom 1: Refrigeration compressor starts up frequently

Cause Analysis:

1. The amplitude difference of the low-voltage relay is too small, or the amplitude difference of the temperature relay is too small.

2. The suction and exhaust valve or safety valve of the compressor leaks, so after the snowflake ice machine stops, the high-pressure gas leaks into the low-pressure system, and the pressure rises quickly to start the compressor; after starting, the pressure of the low-pressure system is quickly pumped down , The low-voltage relay acts to shut down again.

3. The automatic oil return valve of the lubricating oil separator leaks;

4. Expansion valve ice plug.

Symptom 2: The compressor runs for too long

Cause Analysis:

1. The evaporator has too much frost or too much oil.

2. The circulation volume of the ice machine in the system is insufficient, or the liquid refrigerant pipeline is blocked.

3. Leakage of the suction and exhaust valves, severe leakage of the piston ring, or failure to increase the load of the compressor, which reduces the actual gas delivery capacity of the compressor.

4. The temperature relay, low voltage relay or liquid supply solenoid valve and other control components fail, so that the storage temperature has reached the lower limit. But the compressor can't stop in time.

The snowflake ice machine compressor plays an important role in ice making. In addition to paying attention to maintenance during normal use, it is also necessary to learn how to judge faults and solve them in a targeted manner.
