Steering Gear Cavitation Prevent Measures
- Nov 03, 2018 -

Let DONGNA,professional steering gear factory share the follow preventive measures of power steering rack with everybody here

(1) Prevent oil temperature from being too high and reduce hydraulic shock

Reasonable design of the heat dissipation system and prevention of excessive oil temperature is the key to maintaining the normal temperature of the hydraulic oil. If an abnormality occurs, you should find the cause and eliminate it in time. When manipulating the hydraulic joystick and the distribution valve, it is necessary to strive for stability, not too fast, too fast, and it is not advisable to increase the engine throttle frequently to minimize the impact of the hydraulic oil on the hydraulic components. At the same time, the cooling system should be maintained in a timely manner to keep the temperature of the cooling system within a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additive may be appropriately added to suppress rust.

(2) Maintain the normal clearance of the joint faces of the hydraulic components

When manufacturing or repairing the main parts of the hydraulic cylinder (such as cylinder block, piston rod, etc.), it should be assembled according to the lower limit of the assembly size. It has been proved that this can reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, the cavitation pitting and surface area charcoal can only be removed by metallographic sandpaper polishing technology, and can not be polished by ordinary fine sandpaper.
