Problems solved by technology

[0004] Among them, the magnetic powder clutch requires additional energy to be controlled, which is usually provided by the engine's accessory generator, resulting in increased fuel consumption and power loss of the engine, affecting the dynamic performance of the engine; in addition, the magnetic powder heat exchanger has slow response speed, poor heat dissipation, and short life. It also affects the running performance of the engine to a certain extent.

Abstract

The invention discloses a control device of an air compressor. The control device comprises an air storage tank communicated with the air compressor, a clutch connected between the air compressor and an engine as well as a control unit, wherein the clutch is an air clutch and is communicated with the atmosphere or the air storage tank through a first directional control valve; a pressure sensor is arranged on the air storage tank; the control unit controls the directional control valve to switch according to the detection value of the pressure sensor so as to enable the air clutch to be in an engaged state or a disengaged state. According to the control device, no additional energy such as a power generator and the like is required, the power loss of the engine can be effectively reduced, so that the power performance of the engine is improved, the oil consumption of the engine can be reduced, and the energy saving performance is good.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a control device for an air compressor. Background technique [0002] The air compressor, referred to as the air compressor, is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover into gas pressure energy, and is a pressure generating device for compressing air. [0003] In automobiles, air compressors are usually required to provide air sources for each pneumatic device of the vehicle. The power of the air compressor is provided by the engine, and the output end of the engine is connected to the connecting mechanism of the air compressor through a magnetic powder clutch. When the air compressor is not required to operate, control the magnetic powder clutch to disconnect and cut off the power transmission between the engine and the air compressor. [0004] Among them, the magnetic powder clutch requires additiona...
