The composition of a pump mainly consists of impeller, pump casing, pump shaft, bearings, and packing sealing device.
Composition of pump
Composition of pump
1、 Divided by working principle into main categories:
Vane pumps can be divided into centrifugal pumps, mixed flow pumps, axial flow pumps, and vortex pumps.
Centrifugal pumps can be divided into single-stage hot oil pumps and multi-stage pumps.
Single pumps can be divided into single suction pumps, double suction pumps, self-priming pumps, and non self-priming pumps.
Multi stage pumps can be divided into segmented and vortex shell types.
Mixed flow pumps can be divided into volute and guide vane types.
Axial flow pumps can be divided into fixed blades and adjustable blades.
Vortex pumps can also be divided into single suction pumps, double suction pumps, self-priming pumps, and non self-priming pumps.
working principle:
A machine that converts mechanical energy into liquid energy for pumping liquids is called a gear pump.
(1) Positive displacement pump: It utilizes the periodic variation of the working chamber volume to transport liquids.
(2) Vane pump: uses the interaction between blades and liquid to transport liquid.
Specific application:
Pumps have different purposes, transport different liquid media, and have different flow rates and head ranges. Therefore, their structures and materials are naturally different. In summary, they can be divided into:
(1) Urban water supply
(2) Sewage system
(3) Civil building system
(4) Agricultural water conservancy system
(5) Power station system
(6) Chemical system
(7) Petroleum industry system
(8) Mining metallurgical system
(9) Light Industry System
(10) Ship system
