往复式压缩机无级气量调节系统故障分析

Analysis of Fault of CVT Gas Regulation System of Reciprocating Compressor

针对往复压缩机无级气量调节系统气阀无法正常卸荷的故障,通过分析无级气量调节系统执行机构阀室活塞输出力、气阀在卸荷状态下卸荷杆反作用力、进气压力以及进气压差等各方面力的构成,并结合现场实际运行状况的数据反馈,找到进气阀无法正常卸载的原因,从而实现零负荷起机。针对此次故障,提出整改方案,消除故障。

Through the analysis of the piston output force of the discharge rod,the reverse force,the intake pressure and the inlet pressure difference,the zero load crane.In view of this fault,put forward a rectification plan,to eliminate the fault.
