Single-phase frequency conversion air compressor

Abstract

The invention discloses a single-phase variable-frequency air compressor, the machine head is fixed in a horizontal oil separator cylinder, the bottom of the horizontal oil separator cylinder and the main motor are fixed with a mounting plate, the mounting plate is fixed at the bottom inside the protective frame, and the machine head It includes a male rotor, a female rotor and a housing. The male rotor and the female rotor are meshed in parallel with each other. Both the male rotor and the female rotor are located in the housing, and both ends of the male rotor and the female rotor are connected to the housing through bearings. The male rotor includes Helical teeth, the female rotor includes a helical groove, and the relative movement between the helical groove and the helical teeth forms a volume chamber with variable volume. The output end of the main motor is fixed with a main pulley, and one end of the male rotor is fixed with a secondary pulley. The frequency conversion speed regulating device includes pressure Sensors and control components, the pressure sensor is fixed in the volume cavity, and the control component is fixed at the bottom inside the protective frame. The invention responds to changes in system pressure in a timely manner, maintains a stable system pressure value, regulates speed smoothly and reduces energy consumption.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a single-phase variable frequency air compressor. Background technique [0002] As the main body of the air source device, the air compressor converts the mechanical energy of the prime mover into the internal energy of the gas. The positive displacement air compressor increases the density of gas molecules per unit volume by compressing the volume of the gas, thereby increasing the pressure of the compressed air, while the speed The air compressor converts the kinetic energy of the gas molecules into the pressure energy of the gas by increasing the movement speed of the gas molecules, thereby increasing the pressure of the compressed air. [0003] As one of the types of positive displacement air compressors, twin-screw air compressors rotate through the meshing of male and female rotors, suck air into the air compressor and compress it, and discharge compressed air that ...

Problems solved by technology

[0003] As one of the types of positive displacement air compressors, twin-screw air compressors rotate through the meshing of male and female rotors, suck air into the air compressor and compress it, and discharge compressed air that meets the pressure requirements. However, common twin-screw air compressors There are defects in the compressor, which are mainly reflected in the high energy consumption, the inability to respond to system pressure changes in time, and adjust the compressor speed
