Abstract

The invention discloses a centrifugal compressor which comprises an operating system, a cooling system and a driving motor. The centrifugal compressor has the beneficial effects that a main driving gear is adopted to drive a primary blade, a secondary blade and a tertiary blade; the structure of the centrifugal compressor is compact, and unnecessary parts are left out to realize integrated drive; a water-cooled oil cooler is adopted; as the specific heat capacity of water is relatively higher, the cooling effect is excellent, and the service life of the oil cooler is long; according to a sealing system, an air sealing part is sleeved with a lubricating oil sealing part; double sealing is realized, so that the sealing effect of the centrifugal compressor is good, and the oil is prevented from leaking out.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a centrifugal compressor. Background technique [0002] Centrifugal compressor (centrifugal compressor), also known as turbo compressor, the main function is to compress gas. It is mainly composed of two parts: the rotor and the stator: the rotor includes the impeller and the shaft, the impeller has blades, a balance disc and a part of the shaft seal; the main body of the stator is the cylinder, and there are diffusers, bends, reflux, air inlet pipes, and exhaust pipes. pipes and other devices. Centrifugal compressors are widely used. Some basic chemical raw materials, such as propylene, ethylene, butadiene, and benzene, can be processed into important chemical products such as plastics, fibers, and rubber. In petrochemical plants producing such basic raw materials, centrifugal compressors also occupy an important position and are one of the key equipment. In addition, centrifugal c...
