Problems solved by technology

[0003] The existing electric intake valve is controlled by a stepping motor, connected with an electric intake valve actuator and signal processor, and then communicates with the upper computer. There are many electrical modules, troublesome installation, complex and cumbersome wiring, many fault points, and untimely signal processing. The action of the electric valve lags behind, resulting in unstable operation, and signal interference is likely to occur due to too many communication cables between the electrical modules, which loses the purpose of high-precision control of the electric valve

Abstract

The invention discloses a control method for an electric air inlet valve of a mobile air compressor, which comprises an electric air inlet valve actuator and an air compressor controller, the electric air inlet valve actuator and the air compressor controller are communicated through an RS-485 bus, a standard MODBUS communication protocol is adopted, the signal processing is more timely, the communication is stable, and the user wiring is simpler; an internal control program can be customized according to user requirements, pressure signals are multi-segmented, functions are richer, and different user requirements are met; the electric air inlet valve actuator additionally has a fault signal real-time feedback function, is safe and reliable, and prevents the potential hazard of ultrahigh pressure of the air compressor caused by misoperation of the electric air inlet valve.

Description

technical field [0001] The invention relates to a method for controlling an electric intake valve of a mobile air compressor. Background technique [0002] The electric intake valve is suitable for mobile oil-injected screw air compressors. It is a normally closed intake valve. The exhaust pressure at the rear end of the air compressor is converted into an analog voltage signal, which is fed back to the control system and the actuator (electric intake valve Actuator) controls the opening of the intake valve plate, and then controls the intake flow of the intake valve to achieve rear-end pressure balance. It is a full-closed-loop control mode, which replaces the traditional cylinder control mode of the intake valve plate opening. The valve plate opening is precisely positioned and stable, and can effectively reduce noise and vibration. It can be applied to lower temperature environments, reduce energy consumption, and achieve energy-saving purposes. [0003] The existing ele...
