Gas compressor with damping boss guide vanes

Abstract

The invention discloses a gas compressor with damping boss guide vanes. The gas compressor is composed of a machine body assembly, a supercharging device and a servo motor. The supercharging device isinstalled between a gas inlet and a main gas chamber of the main body assembly, gas supercharging is achieved, the supercharging process is stable, energy consumption is low, and high supercharging is achieved according to practical requirements. The servo motor is installed on the outer wall side of a shell. The guide vanes adopted in the gas compressor are simple in structure, damping bosses inthe middles of the guide vanes and the vanes are assembled to be in an annular shape to restrict each other, rigidity is increased, the inherent frequency of the vanes is changed, the bending torsional stress of the roots of the vanes is reduced, damping boss combined faces of the guide vanes are sprayed with wear resisting alloy, and the damping effect can be achieved during vibration of the guide vanes. Impellers adopted in the gas compressor are large in gas suction amount, low in noise, high in working efficiency, no prone to deformation and damage and long in service life, flow equalizing processing for gas suction and gas exhaust can be achieved, and balance of gas pressure in the shell is ensured.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor with guide vanes on shock-absorbing bosses. Background technique [0002] The compressor is a component in a gas turbine engine that uses high-speed rotating blades to do work to increase air pressure. The front part of the compressor impeller blade is curved and called the guide wheel, and its function is to guide the gas into the working impeller without impact, reducing the impact loss of the air flow. The compressor impeller of a small supercharger generally integrates the guide wheel and the working impeller. There is a diffuser at the outlet of the impeller of the compressor, so that the kinetic energy obtained by the gas in the impeller can be converted into pressure as much as possible. There are two types of diffusers: vane type and slot type. The casing of the compressor has inlets and outlets for airflow. The inlet is generally arranged ax...
