Pumps in a pipe system are used to convert mechanical energy into hydraulic energy this additional energy allows a fluid to move when it is not possible by gravity and for example, to raise a fluid at a certain height above the pump or make it recycle in a closed system. The working principle of a centrifugal pump is based on the fluid inlet in the middle of the impeller, which blades conduct the fluid and thanks to the centrifugal force it is driven outward. In general, the main purpose of a pump in a system is to increase the total energy H. At this point, the fluid is collected and contained by the pump casing which, thanks to its shape, drives the fluid to the outlet pipes or to another impelling stage.
Module For Centrifugal Pump Characteristics is made through a frequency inverter which adjusts the working speed according to each case of study. Module For Centrifugal Pump Characteristics equipment allows the study of the characteristics of a pump working individually at different rotational speeds. These curves can be compared with those supplied by the manufacturer, as well as those obtained by mathematical calculation. The flow measurements are made using volumetric hydraulic of the hydraulic bank (required), that is used also to study the relation between pressure loss and the fluid speed. In addition, the flow control valve manages the pump operating mode in order to obtain experimental operating curves.
The unit consists of a forward curved variable speed centrifugal fan and integral control console together with a rectangular air intake and filter holder.
A realistically scaled ventilation training unit capable of enabling students to study both basic airflow and fluid mechanics as well as the more complex process of commissioning and balancing a multi - ducted air distribution system.
Sufficient components are supplied with the unit to enable parallel branch and line balancing experiments to be undertaken. A minimum of 6 air supply points are provided that may be balanced on the assembled unit to supply a range of air flows.
A portable manometer, pitot static tube and hand held anemometer allow a large range of experiments to be undertaken.
The fan has a supply pressure of up to 350Nm-2 and a flow rate of approximately 1400m3h-1 depending upon the blockage factor.
The fan discharges directly into a 200mm dia. galvanised steel duct and this connects directly to the distribution duct work.
The dial gauge can be used to set the upper dead centreexactly on the timing wheel, and thus determine all other piston positions. The engine can be turned easily.

Crankcase
Air filter
Valve timing
Cylinder
Cylinder head
Tank
Carburetor and ignition.
