How should the water pump be classified?

The classification of water pumps cannot be integrated and used, which will be very messy. The purpose is to use, the principle is the principle, and different principles of the pump can be used in the same use. The same pump can also be used in different places and can be used in different USES. For example, the mixed flow pump is the oblique flow pump, which adopts the mixed flow impeller, that is, the direction of the liquid outflow impeller is tilted to the axis. The flow direction of the axial flow pump is parallel to the axis. Its classification is important to include sewage pump, chemical pump, magnetic pump, oil pump, pump, fire pump, vacuum pump, diaphragm pump, screw pump, pipeline pump, liquid bottom pump, reciprocating pump, colic grinding, water supply, and drainage equipment, hydraulic injector, control cabinet and so on as follows:

According to the working principle:

Vane pump

Blade pump can be divided into the centrifugal pump, mixed flow pump, axial flow pump, and vortex pump.

Centrifugal pumps can be divided into single-stage pumps and multistage pumps.

Single-stage pumps can be divided into single suction pumps, double suction pumps, self-pricing pumps, non-self-pricing pumps, and so on.

The multistage pump can be divided into segment type and vortex shell type.

A mixed flow pump can divide vortex shell type and guide vane type.

Axial flow pumps can be divided into fixed blades and adjustable blades.

Vortex pump can also be divided into the single suction pump, double suction pump, self-primed pump, non-self-primed pump, and submersible pump.

How should the water pump be classified?

Volumetric pump

The volume pump can be divided into the reciprocating pump and rotor pump.

The displacement pump is attached to the working element in the pump cylinder for reciprocating or rotating activities so that the working volume can be increased and reduced alternately, so as to achieve liquid suction and discharge. The volumetric pump for reciprocating activities is called the reciprocating pump, and the rotary pump is called the rotary pump for rotary activity. The former suction and discharge process is delivered in the same pump cylinder and controlled by the suction valve and discharge valve; The latter is through the rotation of gear, screw, blade rotor or slider, and other working elements, forcing the liquid to transfer from the suction side to the discharge side, the sewage pump.

The flow rate of the displacement pump under a certain speed or reciprocating times is certain, and hardly changes with pressure; The flow rate and pressure of the reciprocating pump have a large pulsation, and a corresponding pulsation reduction method is required. The rotary pump generally has no pulsation or only small pulsation, diaphragm pump; With self-priming ability, centrifugal pump, the pump can be used to drain the air in the pipeline to absorb the liquid; The discharge line valve must be fully opened when starting the pump; Reciprocating pump is practical in high-pressure force and small flow rate; Rotary pump is practical for small and medium flow and high pressure; Reciprocating pump suitable for conveying clean liquid or gas-liquid mixture, chemical pump. In general, the efficiency of a volume pump is higher than that of a power pump.

Jet pump

It is the high-speed jet induced by the workflow body, and then the energy of the led jet body is increased by momentum communication.

Power pump

The power pump relies on the force of the rapidly rotating impeller on the liquid, which transfers the mechanical energy to the liquid so that its kinetic energy and pressure can be added, and then through the pump cylinder, most of the kinetic energy is converted into pressure energy and transported. Power pump is also called an impeller pump or blade pump.

Centrifugal pump

Centrifugal pump is the most common power pump.

The head of the power pump at a certain speed has a certain limit value, magnetic pump, the head changes with the flow rate; Stable work, self-pricing pump, conveying continuous, flow and pressure without pulsation; Generally no self-prizing ability, need to fill the pump first liquid or pump into the pipeline after pumping into empty, pump; Wide range of practical performance; Suitable for conveying clean liquid with low viscosity, specially designed pumps can transport mud, sewage or water to transport solid substances. Power pump is important for water supply, drainage, irrigation, flow liquid transport, power station energy storage, hydraulic transmission ship injection propulsion.

Other classification of pumps

In addition to the working principle classification, the pump can also be classified and named in other ways. For example, according to the driving method, it can be divided into electric pump, steam turbine pump, diesel pump and hydraulic pump. The structure can be divided into single-stage pumps and multistage pumps; According to the use can be divided into boiler feed pumps and metering pumps, etc. According to the nature of liquid transport can be divided into the water pump, oil pump and mud pump
