Description:

• The test rig consists of a closed water circuit with water tank, a piston pumps with variable speed via a frequency converter and an air vessel.
• The position of the piston rod is measured by an angle sensor.
• This allows the determination of the cylinder volume.
• The pulsating pressure curve of the pump can be damped with the aid of the air vessel.
• Flow rate and head are adjusted via a needle valve and overflow valve.
• The experimental unit is fitted with sensors for pressure and flow rate.
• The microprocessor-based measuring technique is well protected in the housing.
• The piston of the pump is mounted in a transparent housing and can be observed during operation.
• The cycle that takes place (intake and discharge of water) can be shown clearly in the p-V diagram.
• One pressure sensor measures the pressure at the outlet of the pump; another one measures the pressure in the inside of the cylinder.
• The measured values are transmitted directly to a PC via USB where they can be analyzed using the software included.
