Advantages and disadvantages of screw refrigeration compressors

Screw refrigeration compressor is a rotary positive displacement compressor. It uses the change of the cogging volume and position of the screw to complete the process of vapor suction, compression and exhaust. Oil-free screw compressors came out in the 1930s, mainly used to compress air. Later, the oil-injected screw compressor appeared in the cylinder,

Treatment method after load damage of screw chiller

First of all, we must confirm whether the compressor load has been burned or the components have been worn away. If so, the refrigerant system will inevitably be contaminated. For example, residual refrigerant oil remains in the pipeline after carbonization

What is the cause of refrigerator compressor not working

What is the cause of refrigerator compressor not working Ambient temperature is too low: it is more difficult to recover, the compressor cannot work for a long time, the compressor oil becomes thicker, and the lubrication performance will be worse; PTC starter failure: if the PTC starter is damaged, you can replace it Overload protector failure: failure occurs, replace it; compressor internal failure: determine that the compressor holds the shaft and replace it. <img src="{{media url=&quot;magefan_blog/What_is_the_cause_of_refrigerator_compressor_not_working.jpg&quot;}}" alt="" />
