Large pumps are generally customized according to customer requirements of the production of each kind of deformation of the pump. Need a complete set of technical meaning.
There are two ways to process the surface of pump impeller, milling method and casting forming method. The milling of the impeller and the mold core and cavity of the casting process all involve the numerical control machining of the curved surface. The accuracy of surface is needed to ensure the hydraulic performance of the pump.
The core technology in the design and manufacture of hydraulic pump is the performance design flow, impeller, volute, guide vane, a flow deflector, a water outlet and a water inlet and grid surface will affect the hydraulic performance of pump. The characteristic of fluid flow determines the flow components and the passage of the water pump are some complex surfaces, because the pump fluid flow is three-dimensional, including vortex flow and turbulent flow, the design should also be considered when the fixed part and a rotating part and fluid interaction.
1.According to the pump model and the speed of the impeller to pump head, flow and efficiency.
2. Calculate the efficiency of the impeller and the head loss of the fluid in the pipeline.
3.Analysis of cavitation generated in the working process and cavitation.
4.Distribution of pressure field and velocity field in the water pump.
5.Water pressure load on the surface of the impeller under the action of fluid.
6.According to the structure of the pump and the rotational speed of the pump to pump drive torque.
7.According to the work under the muddy water pump parameter data Ting parameters.
Under certain conditions should check and test of muddy water in the muddy water under the condition of parameter correction.
In addition, the structural strength of the pump, the fatigue life of components and the structure dynamics are analyzed, so as to reduce the vibration and improve the dynamic performance of the water pump through the structure optimization. The most basic and most important analysis is to solve the system's natural frequency and corresponding vibration mode, to provide the basis for the selection of the motor.
