Centrifugal Water Pump Design

Centrifugal pumps are normally single impeller type pumps and are widely used in water transfer.

Centrifugal water pump design. The performance or characteristic curve of the pump 13. End suction pumps are used in a large range of applications. The pressure velocity coupling is performed through the simple algorithm. The rotational energy typically comes from an engine or electric motor.

Most typically a radial flow impeller would be used but in certain specialty applications francis vane or mixed flow impellers may be used. This project simulates a typical centrifugal water pump using the steady state multiple reference frame mrf method and the k omega sst turbulence model. In these pumps water enters axially and is discharged by the rotor into a discharge pipe. Determine the type of centrifugal pump needed.

In many cases this will be the bathtub which requires approximately 10 gpm 0 6 l s. How to determine friction head 12. A typical water supply pump design would choose a high speed pump. As pump manufacturers build pumps for particular purposes the characteristic of the impeller and volute change depending on what is being pumped and the desired flow velocity.

A centrifugal pump is of very simple design. These pumps are used for different applications including pressure boosting wastewater water supply heating and cooling distribution and other industrial applications. The only moving part is an impeller attached to a shaft that is driven by the motor. The two main parts of the pump are the impeller and diffuser.

Determine the flow rate. Centrifugal pumps constitute more than 85 of the world production of pumps due to their capacity to handle high flows. How to select a centrifugal pump examples of total head calculations sizing a pump for a home owner application 14. Centrifugal pump design optimization with cfd.

As a general rule they deliver a large amount of water at a relatively low pressure. To size and select a centrifugal pump first determine the flow rate. The steps to follow to select a centrifugal pump are. For our case study we will use this simulation project as a template.

In fact there is a design of centrifugal pump suitable for virtually any application involving low viscosity fluids. They have an impeller which rotates in a casing of a special shape. The most common centrifugal pump design is the end suction pump. This type of pump combines a volute casing with a variety of impeller designs.

The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller. Centrifugal pumps are commonly used for pumping water solvents organics oils acids bases and any thin liquids in both industrial agricultural and domestic applications. If you are a home owner find out which of your uses for water is the biggest consumer. What is total head 10 what is the relationship between head and total head 11.

How does a centrifugal pump produce pressure 9.
