What are the common faults of compressors in industrial chillers?

What are the common faults of compressors in industrial chillers?
Poor compression
1 Poor compression, too high suction pressure, too low discharge pressure
2 compressor current is too small
The cause of overheating of the second compressor
1 Low voltage 2 High power 3 Insufficient refrigerant (low suction pressure) 4 Excessive pressure 5 Low oil 6 Valve broken 7 Liquid tube blocked 8 Expansion valve blocked 9 High compression ratio
Three mechanical failure
1 During light load operation, ON-OFF starts and stops, causing the eye spring to break.
2 The expansion valve action or the temperature sensing rod is placed poorly, causing the liquid in the compressor to return to the liquid, causing hydraulic damage to the valve.
Four noise
1 Compressed sound - The discharge pressure is too high and the refrigerant is too hot.
2 Internal noise - the suspension spring is broken and the rotor and stator of the motor are in contact.
3 motor sound - low voltage, compressor coil burnt odor, bearing damage, rotor and stator.
4 Metal tone - The valve is damaged and the spit tube is broken.

Roofing Tile Roll Forming Machine

 

Working principle:

Steel plate or steel strip is made into roofing tile by machine through cold-bend forming technology.

 

Usage:

Steel roofing tiles produced by roll forming machine are widely used in construction, transportation and other industries. It is mainly used for roofing and wall of buildings, such as steel structures, airports, storehouses,etc.
