Chemical pumps (stainless steel) are widely used in petroleum, chemical, metallurgy, synthetic fiber, pharmaceutical, food, synthetic fiber and other sectors to transport alkaline Corrosive medium; 2) Chemical pump (material of fluoroplastic) is used to transport any acidic or alkaline corrosive medium; 3) Chemical pump (material of cast iron) is used for industrial and urban water supply and drainage, and can also be used for irrigation and drainage of farmland and orchard. Four. Vertical magnetic gear oil pump selection requirements: 1.
The chemical properties of the medium: including the corrosiveness and thermal stability of the medium. (4) Cavitation occurs at the inlet If the suction pressure of the pump is too low, lower than the saturated vapor pressure of the pumped medium, cavitation will form. Other characteristics of the medium:
Whether the medium has lubricity, whether it contains fibers or particles, etc. 3) Impurity pump: including slurry pump, sand pump, sewage pump, pulverized coal pump, ash pump, etc.Generally, centrifugal pumps have a continuous downward performance curve, and the flow gradually increases as the head decreases. If part of the flow passage of the impeller is blocked, the work of the impeller will be affected and the outlet pressure China drainage pumps factory will drop. It is necessary to figure out the medium, viscosity, temperature, and inlet and outlet pipelines carried by the magnetic gear oil pump, and reasonably calculate the pipeline resistance of the gear oil pump in practice. (6) The impeller flow passage is blocked. 4. Construction site conditions: You must understand the user’s site conditions in detail, and select the model according to the detailed site conditions provided by the customer.
The performance and technical requirements of the pump are designed according to the performance and size specified in the international standard ISO2858., whether it is easy to crystallize or solidify, these characteristics must be fully considered. 4) Oil pumps: cold oil pumps, hot oil pumps, submersible oil pumps, slurry pumps, liquid hydrocarbon pumps, etc
