Screw compressor principle and structure content Screw compressor characteristics Screw compression principle DXS compressor structure Application of DXS compressor in YCWS unit Screw compressor characteristics
Characteristics of screw compressor -----Internal compression, forced exhaust ----Continuous gas transmission, stable pressure ----Exhaust volume does not change with exhaust pressure, no surge ---Spool adjustment, variable volume ratio, variable pressure ratio ---High speed, low exhaust temperature, high efficiency,
Compression principle Ideal gas state equation: PV=nRT Gas compression: ---Volume reduction --- increased pressure ---Temperature rise
Compression principle Primitive volume ---It is made of Yin-Yang rotor tooth surface, contact line, shell and end cover. ----As the turning angle gradually increases and then shrinks.
Compression principle Three main factors affecting the compression process - Rotor. Profile, twist angle, lead, speed --gap. Between the rotor, between the rotor and the body, the exhaust end face - Fuel injection. Oil quality, temperature, fuel injection
The role of fuel injection --cool down --lubricating --seal --Noise reduction DXS compressor structure DXS--Direct expansion screw Application: chiller, heat pump, industrial refrigeration
