螺杆压缩机排气压力异常原因分析及排除

Analysis and Elimination for Abnormal Discharge Pressure of Screw Compressor

螺杆压缩机排气压力异常是一种常见故障,在近10年的设备运行及维修经验的基础上,对设备出现的各种问题进行分类归纳。螺杆压缩机产生排气压力异常的故障原因主要有:排气压力检测取样系统故障;CPU微电脑控制系统故障;进气阀控制系统故障;加卸载控制系统故障;空气流程系统故障。同时,结合维修中的实例,对螺杆压缩机产生排气压力异常的故障原因进行了深入研究和分析总结。

Abnormal discharge pressure of screw compressor is a common fault. The problems of equipment are classified and summa-rized based on the equipment operation and repair experience during nearly ten years. The reasons of abnormal discharge pressure of screw compressor contain that the sampling system fault of exhaust pressure detection, the control system fault of CPU microcomputer,the control system fault of intake valve, the control system fault of loading or unloading and the fault of the air process system. And the causes for abnormal discharge pressure of screw compressor according to the example of repair are studied and analyzed in depth.
