Isn’t the pump-motor interlock triggered by the signal of the motor power supply being turned on or off? What are the reasons for not providing a barring gear?
This refers to particularly important equipment, such as emergency loads; when another operating pump suddenly stops functioning, this pump is designed to start automatically as part of the interlock system, so as to ensure that the system does not stop working. Such equipment is in a super hot standby state and has been powered on; it will start immediately once the interlock conditions are met. Therefore, turning the shaft is strictly prohibited! ! !
The machine may start up automatically during cranking, which can cause injury to people~~ Cranking is only possible if the interlock is disabled~~
It would be more accurate to label this device as “Self-starting device; cranking prohibited” or “Interlocked starting device; cranking prohibited”.
