The type, purpose, and principle of water pumps

2024.03.18
Definition of water pump
Usually, machines that lift, transport, or increase the pressure of liquids, that is, convert the mechanical energy of the prime mover into liquid energy to achieve the purpose of pumping liquids, are collectively referred to as pumps.
Working principle of water pump 2
Positive displacement pump: uses periodic changes in the working chamber volume to transport liquids.
Vane pump: uses the interaction between blades and liquid to transport liquid.
3. Specific uses of pumps
Pumps have different uses, different liquid media, different flow rates, and head ranges. Therefore, their structural forms and materials are also different. In summary, they can be roughly divided into:
Urban water supply
Sewage system
Civil and architectural systems
Agricultural water conservancy system
Power plant system
Chemical system
Petroleum industry system
Mining Metallurgical System
Light industrial system
Ship system
4 Classification of pump types
According to the working principle of the pump, it is divided into:
1. Centrifugal pump 2, vortex pump 3, mixed flow pump 4, axial flow pump 5, electric pump 6, steam pump 7, gear pump 8, screw pump 9, Roots pump 10, sliding vane pump 11, jet pump 12, lifting pump 13, electromagnetic pump 14, submersible pump, etc
Classified by purpose:
1. Clear water pump, 2, slurry pump, 3, sewage pump, 4, chemical pump, 5, oil pump, etc
Other division methods:
There are many other classification methods for water pumps: they are divided into single-stage and multi-stage pumps based on whether the impellers are connected in series; According to whether the water pump has one or two suction ports, it can be divided into single suction pumps and double suction pumps, etc.
