Rubber seal lip due to the negative pressure release lined slurry pump, and the sleeve produce a certain gap between them to reduce pump wear and prolong the service life; shutdown, since the sub impeller (or vice-blade) stops rotating sealed chamber by the negative into the positive pressure, the seal started to stop working, the rubber lip seal under pressure to tightly wrap the bush, so as to achieve sealing purposes. If cooling water is allowed to penetrate into the media mortar pump mechanical seal, can be used with cooling water K-type dynamic seal, you can add external cooling water installations, extend seal life. The seal oil seal fluorine rubber, mainly used to transport slurry containing solid particles containing impurities, water and other corrosive media (with K-type dynamic seal cooling water cooling water with clean water fluorine plastic mortar pump, Suitable pressure within 0.05Mpa). Centrifugal force (or vice-blade) generated by the rotation of the seal chamber in a vacuum state, thereby preventing the liquid from leaking out, this time, stop seal ineffective. 6) low coefficient of friction: the friction within the pump system is only 0.07-0.11, it has a self-lubricating. In the water-lubricated conditions, the dynamic friction coefficient is lower than PA66 and POM (POM) half. When the form of a sliding or rotating work even better than steel and brass plus lubricant after lubrication. Fluorine plastic mortar pump, pump, 250UHB-ZK-500-26 Limited by Shijiazhuang-send pump. Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) strong, credible, and other industries in other Shijiazhuang, Hebei accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Shijiazhuang-faction pump into the brilliant and you work for a better future!
