A self-contained, fl oor-standing mobile unit consisting of a water reservoir, pump, calibrated nozzle and valves. It allows students to study and perform tests on an axial fl ow pump, to understand how it works and calculate its performance.
Key features
• Axial fl ow pump, mounted in a mobile frame with full instrumentation, including a digital pressure display
• Self-contained, has its own water reservoir and needs no external water supply
• Part of TecQuipment’s Modular Fluid Power range which connects with the Universal Dynamometer (MFP100) as a common motive-power source for a cost-eff ective solution
• Allows students to study and test a common type of rotodynamic pump, safely and at a realistic scale
• Connection plate with schematic diagram shows the water fl ow circuit and how parts of the module connect to each other
• Fully variable speed and fl ow, for range of tests
• Works with TecQuipment’s Versatile Data Acquisition System (VDAS®)
Description
For use with the Universal Dynamometer (MFP100), the Axial Flow Pump Module is part of TecQuipment’s Modular Fluid Power range. The Axial Flow Pump Module is ideal for student experiments, demonstrations and projects.
Axial fl ow pumps are common machines, used to pump water and other liquids. They can be as small as a few centimetres in domestic use, or up to a metre when used in large irrigation systems. They give high fl ow rates at a reasonable pressure. The pump fi tted to this module has two sections - one fi xed and one moving, each with a set of blades.
The module has an axial fl ow pump and instrumentation, all mounted on a robust, mobile trolley for ease of use. The module is for use with and driven by TecQuipment’s Universal Dynamometer (refer to MFP100 datasheet). The Universal Dynamometer measures the speed, torque and power absorbed by the pump. Speed is fully variable up to the maximum allowable for the pump.
Water moves from a water tank through a calibrated nozzle. It then passes through the pump and down to a fully adjustable delivery valve. It then returns to the water tank. The delivery valve allows the user to gradually shut the downstream water fl ow for a range of pump performance tests.
Electronic transducers measure the pump inlet and outlet pressures, and the pressure diff erence across the nozzle. A digital display shows all the readings.
For quick and reliable tests, TecQuipment can supply the optional VDAS (Versatile Data Acquisition System). VDAS gives accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer. The computer is not supplied.
