Rubber seal lip due to the negative pressure is released and the sleeve produce a certain gap between them to reduce wear and prolong the service life; when you stop the pump, since the sub impeller (or vice-blade) stops rotating seal cavity is defined by negative into a positive pressure, the seal started to work the parking fluorine plastic mortar pump, rubber lip seal under pressure to tightly wrap the bush, so as to achieve sealing purposes. If cooling water is allowed to penetrate the media, can be used with cooling water K-type dynamic sealing mortar pump mechanical 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 cooling water (with cooling water K-type dynamic sealing for clean water, suitable pressure in 0.05 Mpa or less). Centrifugal force (or vice-blade) generated by the rotation of the seal chamber under negative pressure slurry pump impeller, thereby preventing the liquid from leaking out, this time, stop seal ineffective. Second, product characteristics: Shijiazhuang-school production of pump UHB-ZK corrosion resistant mortar pump type can adapt to a variety of working conditions of pumps, such as transport acid, alkaline serum or slurry; smelting Industry corrosive slurry; various types of dilute sulfuric acid industry; environmental protection industry, all kinds of sewage. The pump is both corrosion and wear resistance, the use of a very wide range. 200UHB-ZK-450-20 fluorine plastic mortar pump (certified merchants) provided by the Shijiazhuang-Pump Co., Ltd. faction.
