Screw chiller-the operation process of refrigeration compressor!

Screw-type (ie twin-screw) refrigeration compressors have a pair of mutually meshing rotors with helical teeth in opposite directions. A rotor with a protruding tooth surface is called a male rotor, and a rotor with a concave tooth surface is called a female rotor. The teeth of the rotor are commensurate with the piston,

Identify true and false filter elements

Look at the filter material. The main filter material of the air filter is filter paper. At present, the filter filter paper mainly uses domestic paper and imported paper. Both domestic and imported paper have good filtering performance, and the inferior filter paper used by the fake filter element cannot prevent dust from entering the engine.
