Definition of a power steering pump
The power steering pump is an important component that allows you to turn the wheels effortlessly. It is a hydraulic system that transfers power from the steering fluid to the wheels. When you turn the steering wheel, a rotary control valve delivers pressure to a piston to help you turn the wheels in either direction. For safety reasons, the system is also able to detect speed and reduce the input speed of the steering wheel to reduce the sensitivity of the system at high speeds.
The role of the power steering pump
1. Provide hydraulic pressure: The main function of the power steering pump is to generate and deliver hydraulic pressure to drive the steering wheel of the car.
2. Power steering: The hydraulic pressure generated by the power steering pump can help the driver operate the steering wheel more easily, making the steering lighter, more accurate and more stable.
3. Improve safety: By reducing the driver’s steering effort, the power steering pump can improve driving safety and comfort.
There are several manifestations of a broken power steering pump
When the power steering pump fails, it usually has the following manifestations:
1. Heavy steering: The steering wheel is difficult to turn, especially at low speed or when parking.
2. Abnormal noise: “squeak” or “hum” sound when turning the steering wheel.
3. Unsmooth steering: There is a jam or uneven turning of the steering wheel.
4. Hydraulic oil leakage: There are hydraulic oil stains on the ground or engine compartment.
5. Hydraulic oil foaming: The hydraulic oil is foamy or milky white.
6. Steering wheel vibration: The steering wheel vibrates abnormally while driving.
7. Hydraulic oil temperature is too high: The hydraulic oil temperature rises abnormally and even smokes.
8. Warning light is on: The power steering system warning light on the instrument panel is on.
Countermeasures
1. Check the hydraulic oil: Make sure the oil level is normal, without leakage or contamination.
2. Listen for abnormal noise: Pay attention to whether there is any abnormal noise when turning the steering wheel.
3. Check the belt: Make sure the power steering pump belt is not loose or worn.
4. Professional diagnosis: If the problem cannot be determined, it is recommended to send it for repair.
