Double stage compression screw machine: double stage compression screw machine compared with the advantages of the piston compressor

With the improvement of people's requirements on using environment, energy consumption and environmental protection, energy saving of refrigeration unit is also one of its development trends. At present, the COP value of the domestic series of two-stage compression screw machine has been higher than the piston compressor, and has achieved stepless energy regulation and adjustable content product ratio within the range of 10-100 percent, which is also conducive to energy saving.

How to deal with high temperature fault of two-stage screw compressor

Compared with the piston air compressor, the screw air compressor has more accessories: sensors, temperature control valves, filters, main controllers, etc., which also makes the screw air compressor more complex than the piston air compressor, and the later maintenance is also more important. Of course, in the face of high temperature environment, the operation status of accessories also needs attention. The comps compressor will explain how to deal with the high temperature fault of the two-stage screw compressor.

Comps compressor explains why the head of the two-stage screw compressor is stuck

Head jamming is a common fault of two-stage screw compressor. It is generally caused by insufficient lubricating oil, but some can be judged only after inspection by maintenance personnel. Here is a detailed explanation of the causes of head jamming of two-stage screw compressor by comps compressor.

Two stage screw compressor: comps compressor specifies how the condensate of the two-stage screw compressor is discharged

During the use of the two-stage compression screw machine, the exhaust temperature will be lower than the air pressure or the shutdown cooling temperature, resulting in a lot of condensate, especially in wet weather or high temperature areas. These air with condensed water condenses in the oil-gas separator. Excessive water in the oil will cause emulsification of the lubricating oil, destroy the quality of the oil and affect the stable operation of the machine.
