How is the selection of pump selection?
The water pump selection basis should be taken into consideration in five aspects according to the process flow and the requirement for water supply and drainage, not only the quantity of liquid, the lift of the device, the nature of the liquid, the arrangement of the pipeline and the operating conditions, etc.
1, flow is one of the important performance data of water pumps. It directly relates to the production capacity and transmission capacity of the whole plant. For example, in the process design of the Design Institute, we can calculate the normal, minimum and maximum flow of three pumps. When the pump is selected, the maximum flow rate is taken into account and the normal flow rate is considered. When there is no maximum flow, it is usually 1.1 times the normal flow rate as the maximum flow rate.
2, the required lift of the installation system is another important performance data for pump selection. Generally, the head lift is selected by enlarging the 5% - 10% surplus.
