【Discussion on Equipment Turning for HaiChuan】01 Which equipment requires turning?
Thread Content
Rotating the pump shaft is a measure to ensure that the pump is in good standby condition. So the question is, which equipment requires turning? Are there any regulatory requirements? Should we refer to the device manual, or rely on past maintenance experience? Let’s all share our thoughts! －－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－ For more series posts, click the link below.

Before starting general operating equipment, it is usually necessary to turn the shaft by hand first; however, some equipment is equipped with such a mechanism while others do not. Large centrifugal units and large pumps generally are equipped with an barring device, while small centrifugal pumps can usually be rotated manually and do not require a barring device.

Which pumps are equipped with interlocks, and can the interlocks be disabled in order to perform shaft rotation?
Which pumps are equipped with interlocks? Is it possible to disable these interlocks in order to perform pump rotation? The oil pumps of the unit and the water pumps of the auxiliary boiler can have their interlocks disabled for the purpose of pump rotation
The so-called \"cranking\" refers to manually rotating the motor a few times before starting it, in order to determine whether there is any jamming or increased resistance in the load driven by the motor (i.e., the mechanical or transmission components). This prevents the starting load on the motor from becoming too high, which could otherwise damage the motor (i.e., cause it to burn out). Therefore, generally, after a shift of shutdown (8 hours), when starting the motor again, it is necessary to turn the shaft.
Isn’t it true that the engine needs to be turned over when it’s idle or after sitting still for a while, not just before driving?
Some just need to be moved and maintained after being left for a while.
All rotating equipment should be turned over, especially thermal rotating equipment, as shown by past experience
