Oil pump overload generally occurs

Page view
[Abstract]:
Oil pump overload usually occurs at low temperature in winter. When the wind turbine fails for a long time, the temperature decreases more, and the oil viscosity increases, resulting in heavy load
   Oil pump overload usually occurs at low temperature in winter. When the wind turbine fails for a long time, the temperature decreases more, and the oil viscosity increases, resulting in heavy load when the oil pump starts, resulting in the oil pump motor overload. The second reason is that the oil seal of oil pump motor output shaft is aging in some units with long service life, resulting in bad contact of oil entering terminal box, unbalanced three-phase current, overload fault of oil pump, more serious situation oil will even enter the oil pump motor winding, destroy air gap of the winding, and form equipment passing. Load. The oil seal should be replaced, the terminal box and motor winding should be cleaned, and the operation should be resumed from scratch after heating and drying.
