Equipment composition:

Aluminum profile frame structure, bottom with wanxiang wheel, flexible movement. There are four centrifugal pumps, two enclosed impeller pumps, one open impeller pump, one multi-stage pump, water storage tank and piping system.

Technical description:

This is a centrifugal pump including dual piston pumps, one as a positive displacement pump and one side tank pump self-priming.

Experiments show that the basic types of operation behavior of various pumps.

The relevant measurements can be read on the digital display.

The height of the pump water is in a closed circuit. In the process, the pump performance data is in the pipeline and pressure loss. The speed of the motor is variable and variably centrifugal pumps are driven by a frequency converter. The operation of centrifugal pump can be configured in parallel or in series. A single pump drives a three-phase AC motor. The engine is installed in the rotating bearing space, so the torque can be measured by the mechanical output power of a single drive sensor.

Students’ experiments with different types of familiarize pumps, such as centrifugal and positive displacement pumps.
