Precision gear pump overload
Cause: Gear Pump overload occurs at low temperature in winter weather conditions, after a long shutdown or a new installation of a wind turbine gearbox temperature is low, increase the viscosity of the lubricant, causing the pump starts when the load is heavy, resulting in pump motor overload.
Approach: The fault should be occur after the unit is in standby mode, gear oil gradually heated to 0 ° C or more, and then start the procedure pumps, fans, to avoid forced starting wind turbine, so as to avoid adverse lubricating oil viscosity greater damage tooth surface or other components bearing and lubrication systems.
