Description
技术领域technical field
本发明属于空压机技术领域，具体涉及一种卸荷式空压机。The invention belongs to the technical field of air compressors, in particular to an unloading air compressor.
背景技术Background technique
空压机是工业生产中必不可少的基础设施，空压机运行的稳定性直接影响生产的可持续性和产品质量的稳定性。传统的空压机在气包内的压力达到一定数值时由压力开关控制自动停机，当气包内的压力降到一定数值时由压力开关控制自动连接启动，这样反复启动电机容易使电机损坏，降低了空压机的使用寿命。Air compressor is an essential infrastructure in industrial production. The stability of air compressor operation directly affects the sustainability of production and the stability of product quality. The traditional air compressor is automatically stopped by the pressure switch when the pressure in the air bag reaches a certain value. When the pressure in the air bag drops to a certain value, it is automatically connected and started by the pressure switch control. In this way, the motor is easily damaged when it is started repeatedly. The service life of the air compressor is reduced.
