FAQ
What are the cause and solution of noise in the special motor for oil pump?
The noise of the special motor for oil pump is mainly divided into three categories: electromagnetic noise, ventilation noise and mechanical noise. However, mechanical noise, as the main common hydraulic motor noise, is mainly caused by five major factors such as oil pump motor rotor sweeping, bearing noise, noise due to housing resonance, oil pump motor body deflection, and magnet looseness. How to reduce the noise of the special motor for the oil pump? The editor of Dalan Motor will tell you one by one how we solved it effectively.
a. The main factor: the noise generated by the rotor sweep of the special motor for the oil pump
Solution: Reassemble the stator and rotor of the special motor for oil pump
b. The main factor: the noise caused by the large bearing clearance in the oil pump motor
Solution: Replace the oil pump motor bearing, pay attention to the selection of the bearing, and pay attention to the size of the radial clearance of the bearing. Excessive radial clearance will increase low-frequency noise, and conversely, too small radial clearance will increase high-frequency noise. For motors with higher noise requirements, low-noise bearings should be used. When the load is small, oil-impregnated sliding bearings can be used. Compared with rolling bearings of the same size, their noise can generally be about 10db less.
