One, work principle: Acid and alkali resistant vertical pump is mainly composed of a liquid storage chamber, a vortex chamber, the backflow hole, impeller, pump cover, pump cavity to be filled with liquid before starting up, the liquid storage chamber at high speed under the drive of impeller gas gas-liquid mixture sucked into the vortex chamber will be pressurized into the gas liquid separation chamber, the air at this time, specific gravity is less than the liquid, then naturally into the network, then the liquid automatically from the reflux hole reflow and the liquid storage chamber air mixed again, by the impeller of circulating vasopressin into the gas-liquid separation chamber ... This process is repeated until the suction pipe in the air is drained; the medium is transported to the conditions needed for any place. Two, structure Acid and alkali resistant vertical pump body using advanced technology to the production of metal shell tightly lining fluorine plastic ( F46 ) manufacturing, pump bearing parts of metal materials with high mechanical strength, strong pressure resistance, resistance to mechanical impact force superior advantages; the main flow components impeller, pump cover are both made of metal insert outsourcing fluorine plastic disposable high temperature molding; configuration mounted outside of metal bellows mechanical seal, the grinding material: aluminum oxide, silicon carbide VS VS PTFE PTFE, hard alloy VS hard alloy, the user can choose according to working requirement of grinding. Three, use: FZB acid vertical pump can be used for storing liquid container 1-4 below ground level meters, inconvenience of intrusion and liquid occasions; the use of the pump is fixed on the plane positions can be continuous or discontinuous extraction, transport all kinds of chemical medium. Vehicle, ship handling chemical medium. Self suction pump can flow in any post extraction and delivery to meet your requirements. Acid and alkali resistant vertical pump can be safely transported acid and alkali, highly toxic, organic solvents, and pure precious chemical mediators, fully meet the stringent safety, reliability and environmental protection requirements. Suitable for a variety of chemical process; once installed without irrigation, bottom valve repair, convenient replacement of heavy liquid pump is the most ideal choice of pump.
