The Sealing Element Of The Hydraulic Valve Is The Factor Of The Valve Body Good Or Bad
The sealing element of the hydraulic valve is the factor of the valve body good or bad
Hydraulic valve is in fact the hydraulic transmission, hydraulic valve used to control the liquid pressure ﹑ flow and direction of the components. and the hydraulic valve seals the damage is the common phenomenon, the main factor is the impurity in the working fluid. The impurities are milled between the sealing elements, causing the valve to leak. Therefore, the corresponding grade of hydraulic components in foreign countries, should adopt the corresponding accuracy of the filter. They think that the 5um oil pump seals, if the filter precision for 3/um filter, the hydraulic valve life can be increased by 10um than 10 times times.
= The use performance of hydraulic valves and the service life of the valve put forward higher requirements. At present, hydraulic valve the life of the valve is measured by the total flow of the emulsion and the number of opening and closing times of the valve in the condition of the filter and the magnetic filter installed in the 120 mesh. But in fact, the indoor type test differs greatly from the downhole actual work result. Now in many countries, hydraulic valve the form of experiments, increased the anti-pollution requirements, and some in the emulsion mixed with appropriate pulverized coal, some of the mechanical impurities.
To this end, the need to use a new, strong anti-pollution, hydraulic valve suitable for the working conditions of the sealing elements, the valve body's service life is of great significance, not only to save the cost of maintenance and improve the production efficiency of customers.
