What is the cavitation of hydraulic pump?

There are many problems in the process of hydraulic work, which requires the hands and users to master some basic skills, and can solve the problem at the critical moment.

High pressure hydraulic system, compact structure, light weight, small size, can absorb the external shocks, and the damping effect of impact load has good adaptability so the main characteristics of the new hydraulic obtained widely described in this article in the engineering machinery vehicle steering system is to shift the flow stability, and not change with the engine the change in speed; straight line driving, steering pump unloading, small energy loss and high efficiency; the volume ratio of the accumulator is small, easy to install.

To hydraulic oil as the working medium of hydraulic system, when the absolute pressure of oil is lower than the air pressure fluid separation, dissolved air in oil will be separated by the large amount of bubbles, which will produce cavitation cavitation harm to the hydraulic system, the liquidity of oil is accompanied by destruction the noise and vibration, low pressure area separated bubble mixed with oil, with the oil flow in the high pressure area, will produce high temperature and pressure local impact instantaneous break, on one hand the performance of the oil change, at the same time, on the surface of metal forming chemical corrosion, with pressure under the impact, the metal surface will be fast erosion and damage.

From the point of view of cavitation, the condition of forming cavitation must be the absolute pressure below the oil in the oil.
