Abstract

The invention relates to an air compressor air inflow control system and a control method thereof. The air compressor air inflow control system comprises an air inflow valve, a stopping air release valve, a circulation unloading valve, a pressure adjusting valve, a loading / unloading solenoid valve, a high / low pressure switching solenoid valve, a one-way valve, an adjustable throttling valve, a filter and a throttle valve. According to the air inlet control scheme, underloading staring of an air compressor can be achieved, low-pressure internal circulation of the air compressor system in the unloading state is maintained, two-gear system working pressure is achieved, starting difficulties of the air compressor can be overcome through the functions, energy-saving operation of the air compressor in the unloading state is guaranteed, and the high / low pressure working pressure of the system can be set according to operation requirements of clients.

Description

technical field [0001] The invention relates to an air compressor intake control system and a control method thereof, which are mainly used in various air compressor equipment. Background technique [0002] Drilling and blasting rock drilling machines are widely used in rock and soil crushing fields such as mining, hydropower, tunnel traffic, etc., and air compressors provide these rock drilling machines with the compressed air required for impact power and slag blowing. With the development of society, the requirements for air compressors are getting higher and higher, especially in terms of energy saving, environmental protection, automation, reliability, etc., which are the focus of various air compressor manufacturers competing for development. [0003] At present, in the traditional air compressor air intake control system, the pressure switch is mostly used as the loading and unloading control element. When the user does not use compressed air and the downstream valve ...
