First, the pump is defined: usually enhance liquid transport fluid or increase the pressure on the liquid, that is the prime mover of the mechanical energy into fluid energy to achieve the purpose of pumping the liquid referred to as the machine pumps.
Second, the pump works:
1, positive displacement pumps: working chamber volume cycle using the transmission fluid.
2, the vane pump: the use of leaves to transport liquid and liquid interactions.
Third, the specific use of the pump: the pump have different purposes, different transport liquid medium, a different flow, head of the range, so it's certainly not the same structure, Materials are also different, summed up, can be divided into:
1, 2 urban water supply, sewage system 3, civil engineering, building systems 4, 5 agricultural water systems, power system, 6, 7 chemical system, the oil industry system 8, 9 mining and metallurgy system, light system 10, the system pumps the ship structure IV pump type classification (a) works under the pump division of:
1, pump 2, 3 mixed-flow pump vortex pump, 4 pump, 5, 6 electric pumps, steam pumps 7, 8 gear pump, screw pump 9, Roots pump, 10, 11 vane pump, jet pump 12 or pump 13, the electromagnetic pump 14, submersible pumps [1] and (b) classified according to use:
1, water pump, 2, 3 slurry pump, sewage pump 4, 5 chemical pump, fuel pump, etc. (c) other classification methods:
There are many other ways into the pump: impeller according to whether the series is divided into single and multi-stage pump; Water Control valves according to a suction pump or two into a single and double suction pump suction pumps, and so on. Innovative multi-stage centrifugal pump innovation innovative self-priming pumps pumps. Pump industry prospects to ensure production and living water, electricity demand, present, China's provinces, many units
