Selection of corrosion-resistant chemical pump basis
When designing equipment, determine the purpose and performance parameters of the corrosion-resistant chemical pump and select the type of pump. This choice must first start from the choice of corrosion-resistant chemical pump type and form, then what principle to choose the pump? What is the basis? do you know? The following describes the selection of corrosion-resistant chemical pump basis. Corrosion-resistant chemical pump selection based on 1, so that the type and performance of the selected pump line with the device flow, head, pressure, temperature, NPSH, suction and other process parameters 2, must meet the requirements of the media characteristics of the transport Flammable, explosive toxic or precious medium pump, shaft seal required reliable or non-leak pump, such as magnetic drive pump (no shaft seal, indirect magnetic field isolated drive) For conveying corrosive media pump, requiring convection parts Corrosion-resistant materials, such as fluorine-plastic corrosion-resistant pumps Pumps containing solid particulate media require that the convection components be wear-resistant and that the shaft seal be rinsed with a cleaning fluid if necessary. 3, the mechanical requirements of high reliability, low noise, small vibration. 4, the correct calculation of pump purchase cost of investment. The basic selection Reference: Design Institute in the design of equipment, to determine the pump usage and performance parameters and select the pump. First of all, this choice from the choice of pump type and form of the beginning, then what principle to choose the pump? What is the basis? First, the corrosion-resistant chemical pump selection principle 1, the selected pump type and performance in line with the device flow, head, pressure, temperature, NPSH, suction and other process parameters 2, must meet the requirements of the media characteristics of Pumps that deliver flammable, explosive toxic or noble media require reliable shaft seals or leak-free pumps such as magnetically driven pumps (shaftless seals, indirect magnetic drive with isolated magnetics) For pumps that deliver aggressive media, convection components The use of corrosion-resistant materials, such as fluorine plastic corrosion-resistant pump delivery of solids containing medium pump, convection parts require wear-resistant materials, if necessary, the shaft seal with a cleaning liquid rinse. 3, the mechanical requirements of high reliability, low noise, small vibration. 4, the correct calculation of pump purchase cost of investment. Second, the following is a reference chemical corrosion-resistant pump selection: 1, conveying corrosive media (such as concentrated sulfuric acid, concentrated nitric acid), the transport of flammable and explosive media, the use of the environment may not have any pollution: the choice of magnetic pump, Such as CQB series of magnetic pumps, IMD series of magnetic pumps, for self-priming, optional ZMD series of magnetic pumps 2, IHF centrifugal pumps and FSB centrifugal pumps with high speed, small size, light weight, high efficiency, large flow, simple structure, Infusion without pulsation, stable performance, easy operation and maintenance features, such as the use of conditions no special requirements, the choice of centrifugal pump is better. 3, the delivery of solid particles containing the chemical medium pump, convection parts require wear-resistant materials: UHB mortar pump for the best selection of objects, UHB corrosion-resistant mortar pump material for high strength new engineering plastics UHBWPE, it is a change Sexual ultra-high molecular weight (5 million or more) polyethylene. In plastic, it has excellent abrasion resistance, the experimental comparison, its wear resistance is much higher than stainless steel, and impact resistance, creep resistance and excellent corrosion resistance (with F4), as well as Adhesion and other unique properties. 8, when the liquid level in the pump below the installation location: Should be used FZB self-priming pump, such as the need to meet the characteristics of the magnetic pump, optional ZMD magnetic self-priming pump Third, according to the pump performance curve to choose the best specifications Model When the requirements of the performance can not be found in the performance parameters of the model can refer to the pump performance curve select the most suitable pump. The above is the selection of corrosion-resistant chemical pump basis, including selection of corrosion-resistant chemical pump principle, selection and reference, etc., hope to help you better choose corrosion-resistant chemical pump.
