The Reason For The Slow Freezing Speed Of Flake Ice Machine 2

Dec. 07, 2019

Some friends report that the freezing speed of the flake ice machine will slow down. So what are the reasons for the slow freezing speed of the direct cooling flake ice machine? The industrial ice maker supplier will then share it with you.

Flake Ice Machine

1. The throttle valve of the flake ice machine is improperly adjusted or blocked, and the refrigerant flow is too large or too small. The blockage of the regulating valve or throttle valve will directly affect the flow of refrigerant into the evaporator. When the throttle valve is opened too large, the refrigerant flow is relatively large and the evaporation pressure and temperature increase. Ice coolers will freeze more slowly. At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow decreases, the refrigerant volume of the system decreases, and the freezing speed slows down.

2. Low compressor efficiency, refrigerating capacity can not meet the ice-making load. The running time of the compressor is long, the wear is serious, the compressor clearance increases, the sealing performance decreases accordingly, the gas transmission coefficient of the compressor also decreases accordingly, the cooling capacity decreases. When the ice-making capacity is less than the ice-making load, the ice-making efficiency decreases. The cooling capacity of the compressor can be roughly determined by observing the suction and exhaust pressure of the compressor. If the cooling capacity of the compressor decreases, the usual method is to replace the cylinder liner and piston ring of the compressor. If the replacement is not effective, other factors should be considered, even remove the machine for maintenance, troubleshooting.

3. Insufficient refrigerating capacity of the ice machine system. There are two main reasons for the lack of refrigerant circulation. One is insufficient refrigerant filling. Another reason is that the system refrigerant leakage is more, in this case, should first find the leak point, focus on the inspection of each.
