Turbo-machinery Laboratory

The FM Service unite is an essential accessory designed to allow self contained operation of the Armfield Turbines FM31, FM32. It has two demonstration set up one is Pelton turbine (FM32) and another is Radial Flow reaction Turbine (FM31). The unit consists of a clear acrylic reservoir, a circulating pump and associated pipe work.

The main objective of these turbines are:

• To study the characteristics of a Turbine
• Comparisons of performances between Nozzles and throttle valves.

The FM33 Propeller Turbine Demonstration Unit is supplied with its own integral floor standing, self contained service unit, consisting of a circulating pump and associated pipe work. The main objective of the unit is to study the characteristics curves for a propeller turbine operating at a range of fluid flow rates.

The FM23 Plunger pump demonstration unit is a positive displacement reciprocating machine. It is supplied with a plunger pump driven by a electric motor mounted on a support plinth together with a acrylic reservoir and a clear volumetric tank and associated pipe work. The main objective of the Demonstration unit is to to study the characteristics curves, obtain the P-V indicator diagram and to show how the volumetric efficiency changes with different system characteristics.

The FM21 series and parallel pump demonstration unit comprises two identical centrifugal water pumps driven by electric motors mounted on a support plinth together with a acrylic reservoir and associated interconnecting pipe work for continuous circulation.

The objectives of this experiment are:

• To obtain a head flow curves for a centrifugal pump operating at inherent speed.
• To obtain head flow curves at  a range of pump speed.
• To check the operating characteristics of two pumps running in a parallel or series.
