IJ Alkali Chemcial Process Pump is a single-stage single-suction cantilever centrifugal pump. It is upgraded and innovative on the basis of TI pump. It is a new standard chemical process pump that replaces IH. The pump is a single-stage single-suction cantilever structure. It is designed with an advanced hydraulic model and has high efficiency. It is 5% higher than the IH pump and is an energy-saving product.
The structural design draws on the American ANSI standard, which increases the shaft diameter and lengthens the cantilever ratio, eliminating the disadvantages of insufficient strength and frequent shaft breaking of the IH pump shaft, improving the operational stability and reducing maintenance costs and operating costs. With reference to the US API682 standard, the mechanical seal and seal cavity structure have been continuously explored and improved. The 179 series static corrosion-resistant and wear-resistant mechanical seals have been successfully used in soda ash, chlor-alkali, salt making, metallurgy, papermaking, environmental protection, etc. Industry and easy to crystallize, multi-particle working conditions. Sealing forms recommended by API 610 can also be used.
After more than ten years of improvement and extended spectrum, the range of use of IJ pumps has been continuously expanded. At present, there are more than 100 specifications. The pump has corrosion resistance, wear resistance, high temperature resistance, non-oxidation, high mechanical strength and stable operation. The structure is advanced and reasonable, the sealing performance is strict and reliable, the disassembly and maintenance is convenient, and the service life is long. Basically covers pressures of 2.0 MPa and all chemical process applications at 300 °C. It is one of the three most widely used chemical process pump series in China with CZ and ZA.
Advantages ● IJ type Alkali Chemcial Process Pump is a standard chemical process pump that is upgraded and innovated on the basis of IH pump. It is designed and developed according to IS02858/GB5662 standard. The technical index has reached the advanced level of similar products at home and abroad. ; ● The pump body, pump cover, impeller and other over-current components are made of high-quality stainless steel. The new technology is precision cast once, no impurities, no porosity, trachoma, and 2205 duplex stainless steel and other high-quality alloy wear-resistant materials are available. ● Shaft seal is self-developed 179 series static anti-corrosion and wear-resistant mechanical seal. It can be used with single end, double end machinery, cartridge type, filling dynamic seal. The sealing surface material for grinding is optional: hard alloy, carbonized Materials such as silicon to meet various working conditions; ● Corrosion-resistant and wear-resistant design, which can transport slurry, crystallize, and the suspended particles are less than 3mm, and the solid content is less than 10%; ● The shaft diameter is increased, the bearing is enlarged, the bearing housing is lengthened, and the torque of the pump shaft is effectively increased, which can effectively carry large specific gravity, easy to crystallize the medium, and does not cause overload, broken shaft, etc.; The amount of lubricating oil in the oil storage chamber and the heat sink of the bearing box effectively reduce the operating temperature of the bearing and improve the service life of the bearing; ● The pump body is axially inhaled and discharged radially. The support body is cast on the pump body and directly fixed on the base. The pump cover is fixed on the suspension body through the stop, and the pump body and the suspension body clamp the pump cover. When the maintenance is removed, the connecting nut between the suspension body and the pump body is removed, and the transmission part of the pump can be withdrawn from the pump body without disassembling the inlet and outlet pipes. For the large-size pump, there is an intermediate lengthening section between the pump coupling and the motor shaft. During the inspection, the motor does not have to be moved. When the middle extension is removed, the transmission part can be withdrawn from the pump body. This is the internationally-used chemical pump structure. It can be interchanged with standard chemical centrifugal pump for user convenience;
● Alkali and inorganic salts: Ammonia-alkali method, ammonia-salt mother liquor produced by the combined alkali method, soda ash, electrolyte, caustic alkali, chloride and hypochlorite produced by membrane alkali and ion-exchange membrane process, alkali sulfide, sulfate, peroxidation Hydrogen, etc. ● Non-ferrous metal smelting: Electrolyzing copper-nickel electrolyte, producing aluminum sodium aluminate, producing cobalt acid mist, producing zinc mineral slurry, producing vanadium ammonium vanadate, producing gold acid mist and thiourea solution, etc. . ● Steel industry: Electroplating, pickling, electrophoretic paint, etc. ● Acid industry: Hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, phosphoric acid slurry, acetic acid, etc. ● Petrochemical: Petroleum refining, cracking, separation, butadiene, alkylbenzene, methanol, etc. ●Synthetic fiber and plastics industry: Polyester, dichloromethane, epichlorohydrin, dichloropropane, polyvinyl chloride, dimethylformamide, etc. ● Paper industry: Pulp cooking liquor, green liquor, white liquor, concentrated black liquor, bleaching liquor. ●Fertilizer industry: Urea, ammonium nitrate, ammonium hydrogencarbonate, ammonium chloride, ammonium phosphate, potassium chloride, potassium sulfate, etc. ● Fermentation industry: Intermediates, lactic acid, citric acid, food additives, beer, various fermentation slurries, etc. ● Environmental protection: Various chemicals, including acid and alkali wastewater.
