Product Details

Technical Description 
Cavitation can play a major role in the vibration of pumps during operation.
With the PT 500.17 accessory set, cavitation can be experimentally induced and its influence on the vibration spectrum investigated. The principal elements of the accessory set are a single-stage centrifugal pump and a storage tank. The pump and tank are interconnected by hoses. Valves and manometers in the delivery and intake lines allow various operating conditions to be set. The transparent plastic pump housing provides a view into the interior of the pump during operation. This enables the formation of cavitation bubbles to be observed. Stroboscopic analysis is specially recommended (stroboscope not supplied).
The pump can be driven directly through a flexible coupling on the base system PT 500 or by the PT 500.14 belt drive.
The accessory set is mounted on the base plate of the machinery diagnostic base system PT 500.
To measure and evaluate the experiment, the computerised vibration analyser PT 500.04 is required. It includes all the necessary sensors, a measurement amplifier and analysis software to record the vibration phenomena.
