1 - the definition of water pump
Usually to enhance the liquid, liquid transport or increase the pressure on the liquid, that is, the mechanical energy of the prime mover into liquid energy to achieve the purpose of pumping liquid machine collectively referred to as the pump.
2-pump working principle
1, positive displacement pump: the use of the working chamber volume change of periodic delivery of liquid.
2, vane pump: the use of leaves and liquid interactions to transport liquid.
3-pump specific use
Pump has different uses, different liquid media, different flow, head range, therefore, its structure is of course not the same, the material is also different, in a word, can be roughly divided into:
1. Urban water supply 2. Sewage system 3. Civil engineering and construction system 4. Agricultural water conservancy system 5. Power station system 6. Chemical system 7. Petroleum industry system 8. Mining and metallurgy system 9. Light industry system 10. Ship system
4-type pump classification
(A) According to the working principle of the pump:
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 vane pump 11 jet pump 12 , Lift pump 13, electromagnetic pump 14, submersible pumps and the like
(B) divided according to use:
1, water pump, 2, slurry pump 3, sewage pump 4, chemical pump 5, pump and so on
(C) other methods of division:
Pump there are many other ways: According to the impeller is divided into single-stage and multi-stage pump; according to the pump suction port is one or two divided into single suction pump and double suction pump and so on.
