A high-quality automobile steering gear booster pump needs to have the following characteristics:

1. High-efficiency performance: A high-quality steering gear booster pump should have an efficient hydraulic system design, which can provide stable hydraulic power output and help the driver easily control the direction of the vehicle. The pump has high working efficiency, which can reduce energy consumption and improve vehicle fuel economy.

2. Durability: High-quality steering gear booster pump should be made of high-strength and wear-resistant materials, which can withstand high pressure and high temperature environment. The key parts of the pump, such as pump body, gear and hydraulic cylinder, should have good corrosion resistance and wear resistance to ensure long-term stable operation.

3. Accurate control: A high-quality steering gear booster pump should have accurate power control function, which can intelligently adjust the power output according to parameters such as vehicle speed and steering force. The solenoid valve and hydraulic system design of the pump should be optimized to ensure that the driver can control the direction of the vehicle more accurately and flexibly.

4. Safety: A high-quality steering gear booster pump should have good safety performance, which can provide power output stably and reliably, so as to ensure that the driver can accurately control the direction of the vehicle under various road conditions. The design of the pump should take into account the emergency control function in case of emergency to ensure driving safety.

5. Silence: A high-quality steering gear booster pump should have low noise and stable working characteristics to reduce noise interference during driving and improve driving comfort. The design and manufacture of the pump should consider reducing vibration and noise to ensure a more pleasant driving experience for the driver.

To sum up, a high-quality automobile steering booster pump should have the characteristics of high efficiency, durability, precise control, safety and quietness to ensure the stability, safety and comfort of vehicle steering. These characteristics will directly affect the driver's driving experience and the overall performance of the vehicle.
