As is known to all, packing element damage is the main factors of the impurity in the working fluid. These impurities grinding between the sealing element, make the leak valve. Abroad, therefore, has put forward the corresponding grades of hydraulic components, should adopt the corresponding precision filter. They thought 5 microns pump seal element, if use filter filtration precision is 3 M/mu, life than 10 times the progress of using 10 microns. But with valve hydraulic support, the work environment is very bad. In the mining face, tubing length of more than 1000 meters, joint pin up to more than 4000, tank no special measures of dust prevention measures. Emulsion in a large number of floating impurities, at the bottom of the cylinder and valve chamber, leaving more of pulverized coal and rock grains and iron filings. Into the liquid valve core and Industrial Valves seat, because open closed more frequently, liquid flow rate is high, seal failure soon. Practice confirmed that reduce support liquid of hydraulic system pollution of impurities, it is very difficult problem, some people imagined in the emulsion pump station adopts high pressure filter, at the same time increase the small filter at the entrance of each bracket. But was quickly blocked in the work, form. On the other hand, with the development of hydraulic support technology. The service life of the function of the use of valve and valve higher requirements are put forward. At present, when equipped with 120 mesh filters and under the premise of magnetic filter unit, the total capacity of emulsion by testing valve and valve opening and closing times, to measure the life of the hydraulic valve. But in fact indoor type testing and downhole working results vary widely. Now many countries in the form of the experiment, increased the anti pollution for, have a plenty of mixed with appropriate coal powder in the emulsion, have a plenty of joining mechanical impurities. Therefore, you need to use the new, strong ability to resist pollution, is suitable for downhole working premise of seal. The service life of all kinds of hydraulic Industrial Valves in hydraulic support is very low, foreign way and solution is to progress system filtration precision and the progress of the emulsion quality, but it is not big.
In the past few decades, os gate valve production has increased because of the use of gate valve.
Shenzhen Mech Valve Trading Co., Ltd. seeks to lead the industry by instilling pride in our customers, creating value for the market and sharing responsibility around the world.
