Pump Classification Application and Working Principle

Due to the wide application scenarios and high operating efficiency of water pumps, it is favored by the majority of users, and the water pump industry has developed rapidly in recent years. SAILINGFLO pump explains in detail the relevant knowledge of water pumps.

Introduction to Water Pump：

A water pump is a machine that transports liquids or pressurizes liquids.

It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspoemulsions and liquid metals.

Water pump purchase：

1) Purchase water pumps according to local conditions. There are 3 types of commonly used agricultural water pumps, namely centrifugal pumps, axial flow pumps and mixed flow pumps.

The head of the centrifugal pump is high, but the water output is not large. It is suitable for mountainous areas and well irrigation areas; (The head of the centrifugal pump is also called the head of the pump, which refers to the energy obtained by the pump per unit weight of fluid.)

The axial flow pump has a large amount of water, but the head is not too high, so it is suitable for use in plain areas;

The water output and head of the mixed flow pump are between the centrifugal pump and the axial flow pump, and it is suitable for use in plains and hilly areas.

Users should choose according to the land conditions, water source and lifting height.

2) Select water pumps that exceed the standard appropriately. After determining the type of water pump, its economic performance should be considered, and special attention should be paid to the head and flow of the water pump.

The selection of quantity and supporting power.

3) Strict procedures for purchasing water pumps. The "three certificates" must be checked when purchasing, that is, agricultural machinery promotion license, production license and product inspection certificate. Only the three certificates can avoid the purchase of obsolete products and inferior products.
