Closed cooling tower supporting the introduction and use of screw refrigeration compressor

- Feb 03, 2016 -

Closed cooling tower supporting screw type refrigeration compressor and piston type refrigeration compressor gas compression methods are the same are positive displacement compressors, meaning that they are relying on the volume change of the gas compression. Is the difference of these two kinds of compressors working volume changes in different ways. Screw type refrigeration compressor is made up of single screw compressors and screw compressors. Twin screw compressors are used in the body of the two has a helical slot screw engages rotation and the body wall and inner wall of the suction and discharge side fit, resulting in changes in volume between teeth, thus completing the process of suction, compression and exhaust gas.

Can be divided into oil-free screw compressor and spray-in two ways. Oil-free screw compressor-30 available primarily for compressed air, 50 is used for refrigeration equipment. 60 's you have the cylinder oil-injected screw compressor, performance is improved. In recent years, with the improvement of tooth and other structures, performance has been greatly improved. Combined screw compressor NET space capacity, high efficiency, no wearing parts such as suction and discharge valves devices. Therefore, screw type refrigeration compressor has become an advanced compressor, especially oil-injected screw compressors are refrigerant compressors one of main machine, has been widely used.

Screw-type compressor mainly consists of casing, rotors, bearings, shaft seals, piston and energy balance adjustment device and so on.

Shell:-as for the split, consisting of body, suction side and discharge side consists of three sections bolted. The cavity of the body double circle intersects the cross 8-shaped cross section, and placed the two meshing rotors of cylindrical surfaces suitable.
