Abstract

The invention discloses method and equipment enabling an air compressor to achieve constant-pressure air supply. The method comprises the steps that the air compressor compresses and conveys out air;an air storage tank at the output end of the air compressor is connected to receive air compressed by the air compressor, and air is supplied to a user; a pressure sensor of the air storage tank is connected to detect air supply pressure in the air storage tank, and a pressure detection signal is output; a controller of the pressure sensor is connected, and a motor control signal is generated according to the difference value of a rated air pressure value P0 and pressure P1 of the pressure detection signal output by the pressure sensor; and a variable frequency motor connected between the controller and the air compressor controls rotation speed for driving the air compressor to work according to the motor control signal output by the controller, and thus the air compressor provides constant-pressure air for the user.

Description

technical field

[0001] The invention relates to the technical field of air compressors, in particular to a method and equipment for enabling an air compressor to realize constant-pressure air supply. Background technique

[0002] The air compressor is a kind of equipment used to compress gas. It is directly driven by the motor to make the crankshaft rotate, and the connecting rod is driven to make the piston reciprocate, causing the volume of the cylinder to change. Due to the change of the pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the intake valve. The directional valve (check valve) enters the air storage tank, and when the exhaust pressure reaches the rated pressure such as 0.7MPa, it is controlled by the pressure switch and automatically shuts down. When the pressure of the gas storage tank drops to a certain value such as 0.3--0.4MPa, the pressure switch is automatically connected and started.
