According to the nature of the liquid being transported can be divided into:
(1) Pumps (type B, type D, type sh) are used to transport clean water and clean liquids with chemical and physical properties similar to water.
(2) corrosion-resistant pump (F-type) used to transport acid, alkali and other corrosive liquids.
(3) Oil pump (Y type) is used to transport petroleum products.
Second, the choice of centrifugal pump
(1) Determine the type according to the nature of the liquid being transported and the operating conditions;
(2) Determine the type of pump (selected from the catalog or catalog) based on the flow rate (usually determined by the production task) and the required head pressure in the pipeline.
(3) If the viscosity and density of the liquid to be transported differ greatly from that of water, the characteristic parameters of the pump should be calculated: flow rate, pressure head and shaft power.
When choosing a centrifugal pump, there may be several types of pumps that meet the requirements of operating in the optimum range at the same time. In this case, you can determine the operating points of each pump, compare the efficiency of the operating point, the preferred choice.
Centrifugal pump is characterized by liquid delivery capacity, uniform flow, but the resulting pressure is not high, and the pressure head with the flow changes.
