Reciprocating Pump Demonstration Unit

Experiments

  • Characteristic curve of a reciprocating pump.

  • Influence of pulsation attenuation.

  • Pressure characteristics of delivery pressure and cylinder pressure.

Specification

  • Reciprocating pump demonstration unit.

  • Reciprocating pump 0.37kW, 155L/h, 30~60m WC Head.

  • Drive motor 230V, 50Hz (Variable Speed with variable frequency drive).

  • Pressure measurement in the cylinder and in the delivery pipe.

  • Volumetric flow rate measurement with compensation tank.

  • Pulsation attenuation of the delivery pressure is damped by using vessel at discharge.

The orifice plate narrows the cross-section in the tube. The constriction of the cross-section causes an increase in velocity which results in a measurable decrease in pressure. Taking the orifice geometry into account, the flow rate can be calculated from the decrease in pressure using Bernoulli’s principle and the Continuity law. The necessary connections are provided for measurement and display of the pressure loss on manometer. The transparent front makes the measuring orifice visible, thus aiding understanding of the operating principle
