    Description  
    Classification of Power Steering Pump
      1. According to the vehicle type, it can be divided into: commercial vehicle steering pump and passenger vehicle steering pump.
      2. From the structural form, it can be divided into: vane steering pump, gear power steering pump, plunger steering pump; the double vane steering pump has characteristics such as small size, low noise, and high volumetric efficiency, and is widely used in various vehicle models.
      3. According to the drive form, it can be divided into: gear-driven steering pump, belt-driven steering pump, cross key (spline) steering pump; the belt-driven steering pump is mainly used for passenger cars with smaller drive torque, while the wheel-driven and cross key types are more common on commercial vehicles.

    Causes and Troubleshooting
      The oil level in the oil tank drops rapidly, and hydraulic oil leaks severely.
      Cause of Failure:
      1. Damage to the connecting pipes in various parts, loose connections, and leakage.
      2. The oil tank is damaged.
      3. The steering gear oil seal is damaged.
      4. The oil seal of the booster pump is damaged, causing hydraulic oil to flow into the engine oil pan.
      Remedial Measures:
      1. Check all connecting oil pipes and joints.
      2. Replace the oil tank.
      3. Remove the steering gear and replace the oil seal.
      4. Repair the booster pump and replace the oil seal.
      When such a failure is found, stop the machine in time to prevent hydraulic oil from mixing with engine oil, causing the engine oil to deteriorate and the engine crankshaft to burn out.
