Abstract
The invention discloses an electric instrument control method for an air compressor. In the air compressor, a pair of mutually parallel and meshed female rotor and male rotor rotates in a cylinder to enable air between rotor alveoli to be continually subjected to periodic volume changes, and then air is conveyed from a suction side to an output side along rotor axes to realize the suction, compression and exhaust overall process of the screw-type air compressor. The electric instrument control method can be applied to the technical field of electric instrument control systems to effectively overcome shortcomings in the prior art so as to realize optimized equipment utilization.
