Proučevali smo odnos potrebne pogonske moči za črpalko BM 105/20 pri različnih vrtljajih priključne gredi in različnega tlaka črpalke. Na podlagi meritev navora in števila vrtljajev na priključni gredi ter tlaka na tlačni strani črpalke je izračunana potrebna moč za pogon črpalke pri različnih vrtljajih priključne gredi in različnih tlakih. Ugotovljeno je bilo, da angažirana moč za pogon črpalke raste linearno z večanjem tlaka ter da se veča z večjim številom vrtljajev priključne gredi.

Abstract

ENGAGED POWER REQUIRED FOR DRIVING AGROMEHANIKA PUMP  BM 105/20

Relation of engaged power required for driving pump BM 105/20 at different speed of pump shaft and different pressures is described. Measurements of torque, speed of  shaft and pressure at driving of pump was carried out and results were used to calculate the power. It was found that engaged power, necessary for driving the pump, grows linearly with the increase of the pump pressure and increases with higher number of revolutions of shaft.
