Volute pump working principle and structure

[Asia Fluid Network News] 1, what is the shell pump? Spiral pump is the most common centrifugal pump, its notable features are: the pump housing is a screw-type, it is called the rotary shell pump; 2, the shell pump structure: spiral pump is a pump body, Wherein the bracket body is located at the top of the pump body, the suction elbow and the base seat are located at the bottom of the pump body, the pump shaft, the upper bearing component and the lower bearing component are located in the bracket body, The impeller is located in the pump body, and the suction elbow and the base are in an integrated structure. The upper bearing component and the lower bearing component are respectively fixed in the bracket body by bolts, and the bracket body is connected with the top of the pump body body by bolts. Volute pump working principle and structure (Asia Fluid Network) Vertical volute pump suction pipe and the base into a part, increasing the suction pipe strength and stiffness, can withstand greater force of the flow medium , Reduce the vibration of the pump body; pump cover and bracket body into a part, the structure is simplified, easy maintenance and repair; upper and lower bearing parts can be removed together from the bracket body, easy maintenance and overhaul. 3, Rotary Shell Pump Working Principle: The working principle of the rotary shell pump is that the driving machine (motor) drives the impeller to rotate through the pump shaft, and the impeller blades drive the liquid to rotate together, thus generating centrifugal force. Under this centrifugal force, the liquid flows along the blade Road was thrown to the impeller exit, the liquid collected by the volute into the discharge tube. The liquid takes energy from the impeller, increases the pressure energy and velocity, and relies on this energy to deliver the liquid to the work site. When an impeller can not get enough liquid energy, the impeller can be used in series or in parallel to work on the fluid. With the above analysis we can see that the volute pump is also working according to the rotation of the impeller at work, though its current use of the scope of a certain limitation, but I believe there will be progress in the market. Volute pump after years of development, already have a certain degree of competitiveness, I believe in the future as long as after reasonable reform and innovation, and constantly improve its usability, and constantly simplify its working principle, but does not change its core strengths, its competitiveness Still worth the wait.
