Series and Parallel Pumps Test Bench With Suction And Loading Mode

Description

The bench include two similar centrifugal pumps but of different powers. The speed of one of the two pumps is controlled by two electronic speed drivers with digital display of the speed and the power consumed. The other pump functions at fixed speed.
A complete instrumentation with pressure gages and flow meters allows to determine the hydraulic power and to draw the characteristic curves of the pumps.

Teaching objectives

Determination of the performances and the features of a centrifugal pump

  • – Measurement of the total manometric height according to the flow
  • – Measurement of the electric power absorbed according to the flow and the speed of the pump
  • – Determination of the hydraulic efficiency
  • – Drawing of the characteristic curves
  • -Study of the two pumps mounted in series and in parallel

Specifications techniques

The bench is mounted on a stainless steel frame with aluminium nuts, equipped of 4 castors, of which 2 are equipped with brakes,
2 feeding tanks
2 industrial single stage centrifugal pumps made of stainless steel 304 (identical rotors, but different powers)
A single-piece pump, with motor mounted in balance with the pump allowing to make a torque measurement with the help of a strain gauge sensor. An electronic tachometer allows to measure the speed of the pump.

The pumps are controlled by two electronic speed drivers

  1. Wattmeter
  2. Rotameters
  3. Vacuum pressure gages
  4. Pressure gauges

Transparent PVC Tubing at the pumps suction
