The DC emergency oil pump 100LY-215-5 is the last oil pressure protection that only starts in an emergency state of the unit (such as sudden loss of auxiliary power). When the DC emergency oil pump is interlocked and started, this condition is already very dangerous because the turbine no longer has backup lubricating oil. Once the DC oil pump malfunctions or the oil pressure further drops, the turbine will cut off oil and burn the bearings. Continuing to operate at the risk of significant damage to the steam turbine is inherently unsafe.

If the DC emergency oil pump 100LY-215-5 is started due to low lubricating oil pressure during normal operation of the steam turbine, the unit must have the following faults: there is a fault in the main oil pump or injector, there is a leak in the pressure oil pipeline system, the oil level in the main oil tank drops, the lubricating oil pressure regulating valve (or overflow valve) is malfunctioning, etc. If the pressure cannot be restored after the AC lubricating oil pump is started, the unit must be shut down for treatment, and if there is a sense of luck, it is necessary to continue running, So it will definitely cause a bigger accident.
