observation and measurement of cavitation

Description:

• Cavitation can play a major role in the vibration of pumps during operation.
• With the PT 500.17accessory 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 500or 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 500.04is required.
• It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena.
