DYNAMIC PUMP
Dynamic pumps impact velocity and pressure to the fluid as it moves past are through the pump impeller and, subsequently convert some of velocity into additional pressure. It is also called kinetic pumps.
Dynamic pumps are one category of pumps under which there are several cases, two of which are:
Centrifugal pump
Special pump
Centrifugal pump
Centrifugal pump is a rotating machine in which flow and pressure are generated dynamically.
The Energy changes occur by virtue of two main parts of the pump, the impeller and the volute or casing.
The function of casing is to collect the liquid discharged by the impeller and to convert some of the kinetic (velocity) energy into pressure energy. It's also called kinetic pumps.
Centrifugal pumps are subdivided into several categories.
Axial flow pump
Mixed flow pump
Radial flow pump
1.Axial flow pump.
Axial flow pumps are high flow, low pressure pumps which lift fluid in a direction parallel to the impeller shaft.
2. mixed flow pump.
Mixed flow pumps are medium flow, medium pressure pumps. Which push fluid out away from the pump shaft at an angle greater than 90°.
3. Radial flow pump.
Radial flow pumps are high pressure, low flow pumps which accelerate fluid along the impeller blades perpendicular to the shaft.
Special pumps
There are also a number of special types of dynamic pumps which are defined by certain characteristics.
Cantilever pump
Jet pump
Turbine pump
1.Cantilever pump
Cantilever pumps are centrifugal pumps which long cantilever design used in sump pump applications.
2. Jet pumps
Jet pumps are kinetic pumps which an ejector attached at the discharge outlet, utilizing the Venturi effect and motive fluid to generating pumping pressure.
3. Turbine pumps
Turbine pumps are centrifugal pumps that use pressure in combination with a rotary mechanism with numerous small impellers and vanes to transfer energy to a fluid.
