the sound produced by the power steering pump when it is working. If there is abnormal noise, check the hydraulic pipeline, pump body and steering gear for oil leakage, whether the hydraulic oil in the storage tank is between the upper limit and the lower limit, whether the transmission belt tightness is normal, and whether the hydraulic oil has deteriorated.
The working principle of the booster pump, the current booster pumps are mainly directional booster pumps and brake vacuum booster pumps. The boosting methods generally include mechanical booster, electronic hydraulic booster, and electric booster. When a signal is sent by the driver by turning the steering wheel or stepping on the brake pedal, the trip computer will determine the boost size according to the current vehicle driving conditions (including vehicle speed, rotation speed, water temperature, etc.). Normally, the steering wheel has a large boost when driving at low speeds, so that the driver can easily control the direction. When driving at high speed, the steering wheel assist is small, which can avoid the driver's accidental operation leading to the sudden steering of the vehicle and improve driving safety.
1. The filter element is not clean and clogged. If there is a lot of dirt and debris, remove it and clean it.
2. The power-assisted pump is not firmly fixed, causing abnormal noise during vibration during work. Be careful not to open the oiler lid when the vehicle is running. Check whether it is in place during the removal and installation process. After all, the steering problem cannot be ignored. Nowadays, most automobile booster pumps adopt electronic boosting method, which is simple in structure and quick in control response. It mostly appears in the power steering, and the maintenance cost of the later maintenance is much lower than that of the hydraulic steering pump. If the power steering pump has abnormal noise, replace it.
