Interior, rod fracture of cylinder etc..At this moment, piston body or cylinder sleeve can hit cylinder cap.When the compressor of installation conventional security monitoring device
When there are these compared with major break down, the parameters such as monitored temperature, pressure, electric current are possible to surpass after generally waiting a few minutes
Mark.Until parameter is exceeded leads to autostop again, compressor is often by badly damaged, or even has occurred that larger
Accident.So in actual operation, compressor is typically all to lean on Field Force's emergency shutdown using unit.It was verified that artificial
When shutdown, from failure judgement to identification failure again to emergency shutdown, a few minutes clock time is generally at least wanted, so can hardly also prevent
Only compressor is damaged.
