Abstract

A volume-variable multi-cylinder rotation compressor is composed of casing, driver unit, at least more than 3 compression units and connection unit. Its running mode features that the volume of compressor can be controlled by 4 classes even if a constant-speed motor is used.

Description

technical field [0001] The present invention relates to a variable-capacity multi-cylinder rotary compressor and its operating method, in particular to a variable-capacity multi-cylinder rotary compressor in which the compression mechanism is composed of three cylinders so that the capacity can be changed to four stages. Compressors and methods of operation thereof. Background technique [0002] Generally speaking, a compressor is a device that uses the power provided by a power generating device such as a motor to apply compression work to air, refrigerant or other special gases, thereby increasing its pressure, and is generally used in the entire industrial field. According to different compression methods, compressors can be divided into volumetric type and turbo type. The positive displacement compressor uses the method of increasing the pressure by reducing the volume, while the turbo compressor uses the method of converting the kinetic energy of the gas into pressure ...
