Bending machine, oil pump motor abnormal sound, what's the matter?
Motor bearings are generally broken, abnormal! If the motor drives the oil pump to work abnormally, then check the bearing of the oil pump or the connecting gear of the motor and the oil pump, whether the gear is intact or not! If the current voice is not expected so but now xigangpian motor inside some manufacturers is a complete xigangpian some manufacturers of the motor is zero material splicing have all kinds of information have a contact number
First look at the bending function can not be used, if can use it is no big deal, if not the first check is not the lack of phase, a phase, do not have to check the pump, check the pump and motor or elastic coupling is not a problem, take another look at the rear cover of fan motor is not with fan met. These are checked, and the bending machine can be used, there is no need to worry about what.
First, the hydraulic oil is not enough, will cause abnormal sound of the pump, check the amount of oil enough;Two, hydraulic oil dirty plug, oil suction port filter will cause abnormal sound, and oil cylinder, motor and other components of the work is not easy, in this case, wash the filter, and filter hydraulic oil or replace hydraulic oil;Three, the pump is damaged, the inner surface of the stator vane pump will wear a different sound, internal plunger piston pump will damage the abnormal noises and vibration of hydraulic system badly, the stress of this situation would not be stable, may be due to a hard object inside the hydraulic oil in the pump caused by card;Basically, these three situations.
