unit consists of the pelton wheel, a needle nozzle used as distributor, a band brake for loading the turbine and a housing with a transparent front panel. the transparent cover enables to observe the water flow, the pelton wheel and the nozzle during operation. the nozzle cross section and thus the flow rate are modified by adjusting the nozzle needle.the turbine torque is determined by force measurement on a band brake and is read on spring balances. for measuring the rotational speed, a non contact speed sensoris provided. a manometer shows the water pressure at the turbine inlet.specification1. function of a pelton turbine2. transparent front panel for observing the operating area3. loading the turbine by use of the band brake4. adjustable nozzle needle for setting

variables of piston pumps.setup features a closed water circuit with water tank, a piston pump with variable speed via a frequency converter and an air vessel. the piston of the pump is mounted in a housing and can be observed during operation. the cycle that takes place ( intake and discharge of water ) can be shown clearly in the p v diagram. the pulsating pressure curve of the pump can be damped with the aid of the air vessel. flow rate and head are adjusted via a needle valve and overflow valve.the experimental unit is fitted with manometer for pressure and sensor for flow rate. pressure manometer measures the pressure at the outlet of the pump.specification:• functioning and operating behaviour of a piston pump• closed water circuit contains piston pump with variable speed via frequency converter, transparent water tank and air vessel•valve for adjusting the flow rate• overflow valve for adjusting the head• pulsation damping of the head using air vessel with bleed
