Novel screw air compressor

Abstract

The invention belongs to the technical field of air compressors and discloses a novel screw type air compressor which comprises an air compressor shell, supporting legs are fixedly connected to the two ends of the bottom side of the air compressor shell, an electrical cabinet is arranged at the top of the air compressor shell, a fixed roller mechanism is fixedly installed in an inner cavity of the air compressor shell, and a movable roller mechanism is meshed with one side of the fixed roller mechanism. The movable roller mechanism is adjustably installed on one side of an inner cavity of the air compressor shell. According to the invention, particles can penetrate through micropores in the surface of the press-fit net sleeve to enter the inner side of the press-fit net sleeve and stay on the surface of the energy-absorbing gasket, so that the adaptive adjustment requirement of the rotation dynamic balance of the shaft body of the extrusion fixed roller is met, and the noise caused by the eccentric rotation of the extrusion fixed roller due to uneven dynamic balance and the increase of compression power consumption are reduced; and meanwhile, the flexible energy absorption gasket supports the pressing net sleeve, so that energy absorption of the contact impact force of the extrusion fixed roller and the pressurization movable roller rotor piece is achieved, and the attachment noise generated during air compression is further reduced.

Description

technical field [0001] The invention belongs to the technical field of air compressors, in particular to a novel screw air compressor. Background technique [0002] The screw air compressor is a device that supplies compressed air through the relative rotation of a complete set of screws to squeeze the air in the cavity. The screw air compressor is equipped with a cooling mechanism and a power supply mechanism, which is convenient to install and has working stability, which can improve the quality Compressed air is widely used in various industries. [0003] Chinese patent document CN109209874B discloses a screw air compressor, which includes a body, a base is provided at the bottom of the body, a hood is arranged inside the body, a male rotor is installed inside the hood, and the male rotor meshes with the female rotor. One end of the male rotor is connected to the hood through a bearing, and the other end of the male rotor is equipped with a driving wheel, the driving whe...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that a small part of particles enter the screw and adhere to the surface of the screw, which affects the dynamic balance stability and heat dissipation capacity of the screw, and affects the durable life of the screw rotor. At the same time, the air compressor passes through the expansion of the bottom cavity Shrinkage adjusts the compression ratio, but the change of the cavity is easy to bring excessive torque load to the screw, and a new type of screw air compressor is proposed
