问题WHATTOCHECK

如何检查1)Drumdoesnotrotateineitherdirection

搅拌罐不能左右旋转Checkoillevelandcondition检查油量和油质Checkinletfilter

检查过滤器Checkcontrolexternallinkage检查外部连接是否泄露Checkcontrolleverforce(70-80kg/cm)检查控制杆力度(70-80kg/cm)Checkpumpcontrolvalvelinkage检查泵控制阀连接是否泄露Checkchargepressure检查充压

OK–checkhighpressurereliefvalve

若正常－检查高压排放阀

Zero–shaftorshaftkeybroken

若为零－轴或轴键损坏

Fluctuated–checkinletfilter

不正常－检查过滤器入口402)Drumrotateinonedirectiononly搅拌罐只能单向旋转Checkpumpcontrolvalveneutraladjustment检查泵控制阀的中和调试

Checkcontrolvalvelinkageandspool检查控制阀内外连接

e.g例如:a)Controlvalvelinkagepinbroken.控制阀连接栓损坏b)Controlshaftwearoff.控制轴磨损Inspectchargecheck-valve检查充单向阀Inspecthighpressurereliefandshuttlevalve检查高压释放阀和回油阀

e.g例如:a)Shuttlevalvespringbroken.回油阀弹簧损坏
