1, positive displacement pump: used to transport liquid cycle working volume change.
2, vane pump, use the blade and liquid interaction to conveying fluid.
Three, the specific use of pump: pump with different USES, different conveying liquid medium, the range of different capacity and head, as a result, the structure of it, of course, is different also,
Material is different also, in summary, which can be roughly divided into:
1, 2, 3, civil sewage system, water supply for the city construction system 4, 5 agricultural water conservancy system, power system
6, chemical system 7, 8 oil industry system, mining metallurgy system 9, 10 light industry system, system of the ship
