The use of performance and service life

With the development of technology. The use of performance and service life of the valve valve put forward higher requirements. Currently, under the conditions when provided with a 120 mesh filter and a magnetic filter device, by using the test valve is opening and closing times of the total flow of the emulsion and the valve, to measure the life of the metric hydraulic hose fittings. But in fact the actual downhole indoor type test results of the work vary greatly. Many countries are now in the form of experiments, an increase of anti-pollution requirements, or the incorporation of appropriate pulverized in emulsion, some added mechanical impurities. To do this, you need to use the new, anti-pollution and strong, suitable for underground working conditions manifold seal pair.
Hydraulic support various hydraulic valve life is very low, foreign ways and means to solve is to improve the precision filtration system and improving the quality of the emulsion, but with little success. This paper analyzes the development process Sealing valve stent, discusses the relationship Sealing materials and sealing performance. Pointed out sealing technology is the key to the hydraulic valve hydraulic support life improved.
