Power Steering Pump for Medium Truck

Steering System matching abnormal noise
(1) This type of abnormal noise is low-frequency noise, similar to the "buzzing" sound of a cow, which is relatively dull
(2) The mechanism of such abnormal sound generation:
Any fluctuations in energy can generate acoustic frequencies. When pumping oil, the oil pump generates an original acoustic wave f1 due to pressure fluctuations. The original wave generates a reflected wave f2 as the hydraulic oil flows through the steering high-pressure oil pipe. The original wave generates a reflected wave f3 as the hydraulic oil flows through the steering gear valve port. When two or three of the three acoustic waves f1, f2, and f3 have the same or similar acoustic frequencies, they generate resonance or resonance and emit low-frequency noise, causing abnormal sound in the steering system.
(3) Treatment methods for such abnormal noises:
The matching resonance of the steering system can be resolved by replacing any system component (steering gear, booster pump, oil pipe, oil tank/filter element).

What is Power Steering Pump?

As the power source of the steering of the car, the power Steering Pump is the "heart" part of the steering system. In developed countries, the installation rate of power steering for large and small cars is close to 100%. At present, many domestic models have begun to use power steering. Therefore, in the process of promoting and using the steering pump, it is necessary to understand and master its performance and principle in order to achieve correct use and maintenance.
