What is the cause of the hydraulic failure?

In general, the cause of hydraulic failure is about 75% to 95% impurities in the hydraulic oil. The inspection mainly includes the following points: cleanliness, color, viscosity and odor of hydraulic oil. The temperature of the hydraulic oil is very high, and the degradation and failure of oxidation on it form a film, which can lead to the formation of corrosion and deposits, as well as the quality of valve groove and accelerated depreciation. The temperature rise will cause the valve and pump to get stuck, and will lead to the temperature rise of safety problems.

Therefore, to check the working temperature of hydraulic oil, it can be seen that oil pollution control is a major work, whether it is the problem of low efficiency or the hydraulic system. The main sources of pollutants are the following aspects: new oil; Assembly process in the system; Enter with the surrounding air; Internal components of oil return filter and corrosive hydraulic power; By leaking or damaged entries, etc.

The hydraulic filter must be used for pollutant monitoring and removal. It can be equipped with a high-pressure filter with a good hydraulic system. The installation position of the high-pressure filter is also very necessary. However, if it is not in good condition and content, it will not play its role and waste costs. Therefore, the following work should be done well: establish a maintenance plan, check the filter replacement system, and detect faults and potential problems.
