Computerized Reciprocating Pump Test Apparatus
Product Code : EL-TMLE-10688
Quick Answer: The Computerized Reciprocating Pump Test Apparatus is an experimental unit used to demonstrate the operating behavior and important characteristic variables of piston pumps, using a closed water circuit with a water tank, a frequency-converter-driven piston pump, and an air vessel. The transparent pump housing allows the intake/discharge cycle to be observed and displayed on a p-V diagram, flow rate and head are adjusted via a needle valve and overflow valve, and pressure sensors, an angle sensor for the piston rod, and microprocessor-based measuring technique send data to a PC via USB for analysis with the included software.
The Computerized Reciprocating Pump Test Apparatus experimental unit provides the basic experiments needed to get to know the operating behavior and the important characteristic variables of piston pumps. The test rig consists of a closed water circuit with a water tank, a piston pump with variable speed via a frequency converter, and an air vessel. The piston of the pump is mounted in a transparent housing so it can be observed during operation, and the cycle that takes place (intake and discharge of water) can be shown clearly in the p-V diagram. The pulsating pressure curve of the pump can be damped with the aid of the air vessel, while flow rate and head are adjusted via a needle valve and an overflow valve.
The experimental unit is fitted with sensors for pressure and flow rate: one pressure sensor measures the pressure at the outlet of the pump, and another measures the pressure inside the cylinder. The position of the piston rod is measured by an angle sensor, which allows the determination of the cylinder volume. The microprocessor-based measuring technique is well protected in the housing, and the measured values are transmitted directly to a PC via USB, where they can be analyzed using the included software.
