What impeller does most centrifugal pumps use?
Fill: 1., the axial force of the closed impeller is smaller; the axial force of the semi open impeller and the open impeller is larger.2. is the use of semi open impeller or open impeller, depending on the characteristics of the transmission medium. That is the viscosity of the medium, the size of the particles and the content of solid particlesThe centrifugal pump is divided according to the selected axis, and is distributed as follows: 3:Radial impellerAxial flow impellerMixed flow impeller
The impeller is the key component of the centrifugal pump, because the liquid gets energy from the impeller, or the function of the impeller is to transfer the mechanical energy of the prime mover to the liquid, so that the static energy and kinetic energy of the centrifugal pump can be improved. The impeller is usually made up of 6~12 curved bladesThe open and semi closed impeller is suitable for the liquid suspension containing solid particles because the flow path is not easy to jam. But because there is no coverWhen the liquid flows between the vanes, it is easy to produce backflow, so the efficiency of the pump is low.
Small to the family of small 220V centrifugal pumps, large to the professional Three Gorges centrifugal pump, centrifugal pump is the most important impeller, impeller closed, semi closed, open type. The characteristics and application of centrifugal pump impeller!!General centrifugal pumps are closed, because the efficiency is relatively high. Semi open and open, I know, used in the delivery of solid particles containing occasions, such as slurry pump, municipal wastewater also open or semi open, at this time, the impeller type has also done a certain change.
