Power Steering Oil Pump with Good Efficiency

Common faults - direction swing head
The performance of steering wheel swing is as follows: When the car is driving, it feels that both front wheels are swinging from side to side, making it difficult to master the steering wheel. The reason is that the adjustment of the ball head of the horizontal and vertical tie rods is too loose (the spring is broken or the adjustment gap is too large); Excessive free travel of steering wheel; The meshing clearance between the steering gear roller and the worm is too large; The clearance between the upper and lower bearings of the worm is too large; Excessive clearance between steering knuckle kingpin and bushing; The front wheel housing bearing assembly is too loose, or the front wheel rim is out of circle and has excessive runout; Front wheel alignment misalignment.

Critical parameters:

Cause of failure and troubleshooting:

The oil level of the oil storage tank drops rapidly, and the hydraulic oil leakage is serious.

Causes of failure:

1. The connecting pipes of each part are damaged, the joints are not tight, and there is leakage.

2. The oil storage tank is damaged.

3. Steering gear oil seal is damaged.

4. The oil seal of the booster pump is damaged, and the hydraulic oil flows into the engine oil pan.

Remedy:

1. Check all connecting oil pipes and joints.

2. Replace the oil storage tank.

3. Disassemble the steering gear and replace the oil seal.

4. Overhaul the booster pump and replace the oil seal.

When such a fault is found, stop the machine in time to prevent the hydraulic oil from being mixed into the engine oil, causing the oil to deteriorate and causing the engine crankshaft to burn out.
