Hydraulic Valve Operation Knowledge

Hydraulic valve is actually hydraulic transmission, used to control the liquid pressure, flow and direction of the components. The hydraulic valve sealing element damage is a common phenomenon, the main factor is the impurities in the working fluid. These impurities are milled between the sealing elements to cause leakage of the valve. Therefore, foreign countries have proposed the corresponding level of hydraulic components, should be used with the appropriate accuracy of the filter. They think 5um pump seal components, if the filter accuracy of 3 / um of the filter, the hydraulic valve life can be improved by 10um 10 times.

= The use of hydraulic valve performance and the valve life of the proposed higher requirements. At present, the life of the valve is measured by the total flow rate of the emulsion passing through the test valve and the number of opening and closing of the valve under the conditions of a filter with a 120 mesh and a magnetic filter. But in fact the indoor type test and the actual results of the actual difference between the great. Now many countries in the form of experimental, increased anti-pollution requirements, some in the emulsion into the appropriate coal, and some add mechanical impurities.

To this end, the need for the use of new, anti-pollution ability, suitable for underground working conditions of the sealing element, the valve life has a very important significance, not only save the cost of maintenance and improve customer productivity.

Hydraulic valve in the use of the process, you can effectively use the adjustment valve core, and the valve body between the orifice area and equipment, the resulting local resistance convection to effectively adjust, it will effectively control the hydraulic valve actuator Movement speed. However, after adjusting the orifice area of the hydraulic valve, it is possible to effectively keep the load pressure little and the speed of the actuator which is not demanding in the movement uniformity is basically kept stable. During the change of the load pressure, Can keep its throttle valve inlet and outlet pressure is fixed.

Above on the hydraulic valve in the application process, it is the process of running knowledge, Xiaobian on the temporary introduction to here, pro who have any questions, you can contact our manufacturers.
