Description

Portable double-screw air compressor

Technical Field

The utility model relates to an air compressor technical field specifically is a portable double screw air compressor.

Background

An air compressor is a device for compressing gas. The air compressor is constructed similarly to a water pump. Most air compressors are reciprocating piston type, rotating vane or rotating screw. The centrifugal compressor is a very large application program, when the compressor works, air is sucked in through a self-cleaning air filter, the air enters a first-stage compression system after being automatically adjusted through an inlet guide vane through a PLC (programmable logic controller) automatic cleaning filter, the temperature of the gas after the first-stage compression is higher, then the gas enters an intercooler for cooling and then enters a second-stage compression system, a suspended full-open check valve is arranged on an exhaust pipeline of the compressor in order to prevent the gas in the system from being poured into a compression cavity (to prevent starting under pressure), the gas discharged by the compressor pushes the check valve open to enter an exhaust silencer, then enters a first-stage aftercooler and a second-stage aftercooler and then enters an exhaust main pipeline;

common air compressors need to protect the motor, as disclosed in chinese patents: "a portable air compressor", publication No.: CN211174515U, but the mode that adopts the backplate protection to the compressor is not convenient for the heat dissipation and the compressor top weight increases and leads to stability to reduce, consequently proposes a portable twin-screw air compressor, thereby increases the ground connection area and improves stability, makes two commentaries on classics board separation and ground connection in the course of the work, has avoided changeing near the board encircleing compressor motor to lead to the not good effect of radiating effect.
