Water Pumps Development Trend
- Aug 27, 2018 -

The requirements for developing agricultural water pumps are to improve efficiency, reduce energy consumption and make full use of natural energy.A large pump instead of several small pumps can improve the unit efficiency, save materials, reduce energy consumption and engineering cost, and facilitate automatic management.Therefore, various large axial-flow pumps and mixed-flow pumps develop rapidly, with the maximum impeller diameter reaching 4.6m and 6.2m respectively, and the matching power reaching up to 12,500 kw. Mixed flow pumps have the tendency to replace part of high-lift axial-flow pumps and low-lift centrifugal pumps.In the deep well water lifting aspect mainly develops the submersible electric pump, its maximum diameter has reached 1 meter, some USES the 6000 volt high voltage motor, the maximum power reaches 2500 kilowatts.The water wheel pump, the wind pull rod pump, the screw pump, various human and animal power drive diaphragm pump, the piston pump and the water pump which is used in the equipment with the sprinkler irrigation, etc., have also received the different degree of attention in China and some other countries.
