Basic model selection of acid and alkali resistant pump

Acid and alkali resistant pump is general mechanical equipment. It is widely used in petroleum, chemical, electric power, metallurgy, mining, choose ship, light industry, agriculture, civil and defense departments.
Model selection steps:
1. List the basic data:
(1) Characteristics of the medium: the name of the medium, specific gravity, viscosity, corrosive, toxic, etc.
(2) Particle diameter and content in the medium
(3) Medium temperature (℃)
(4) The flow required: generally industrial acid and alkali resistant pump can ignore leakage of piping system in the technological process. Agricultural acid and alkali resistant pump, if it adopts to open channel, leakage and evaporation must be considered.
(5) Pressure: suction tank pressure, drain tank pressure, pressure drop in the piping system(head loss)
(6) Piping system data (pipe diameter, length, the type and number of piping accessories, geometric elevation from suction tank to drain tank, etc.) If necessary, you can do the device characteristic curve.
2. Determine the flow and head
(1) The determination of flow
If the production process has made sure minimum, normal and maximum flow rate, the maximum flow should be considered.
If the production process only make sure the normal flow rate, a margin should be considered.
If the basic data only give the weight flow, you should convert to volume flow rate.
