Understanding Irrigation Pumps

The pump is a type of machine that serves to move the substance flow (fluid) including piped water from one place to another by providing mechanical energy to the pump which is then converted into mechanical energy. Pump specifications stated with the amount of fluid that can flow per unit of time and the high-energy lift. In these functions the ...

Centrifugal Pumps Section

The parts of centrifugal pumps is as follows, (1) casing, (2) blades, (3) inlet, (4) nozzles (diffuser) and a outlet. a. Casing (home conch) Its function is to change or convert fluid energy into static pressure energy. b. Blade Its function is to convert the kinetic energy or provide kinetic energy to the liquid, and then in the casing is ...

Characteristic Curves Pump

Pump characteristic curve also called the performance curve, describes the relationship between capacity, head, power and efficiency of pump (Figure 9:17). Knowledge pump characteristic curve is required to select a pump on certain operational conditions that give high efficiency and low operating costs. Generally Head, input power and efficiency is structured as ordinate while the capacity as abscissa at a ...

Working Pump Positive

On a positive working pump fluid pressure increase in the pump room caused by the downsizing of the volume occupied by the liquid. The existence of elements that move in the room causes the volume of the room will be enlarged or shrunk in accordance with the movement of the element. In general, positive working pumps classified into: a. Piston ...

Parameter Irrigation Pumps

a. atmospheric pressure Atmospheric pressure is the air pressure at any point on the Earth’s atmosphere. The air pressure in each layer mempersentasikan total mass of the airspace above those levels. Reduced air pressure at different altitudes. Although the air seems lighter, if it has a large column of air at the Earth’s surface would produce a pressure of about ...
