if desired, and all instruments and controllers.
- Head/capacity, flow/efficiency
and NPSH determination
- Observation of cavitation
phenomena
- Custom designed for technician/undergraduate
teaching
- Complete visual monitoring
- Easily operated and used
- No further development
work necessary
Specification
A QVF fluid transport teaching
system module comprising a single phase motor driven centrifugal pump,
variable area flow meter, flow control valve, recirculating lines and
vapor disengagement vessel, all manufactured in borosilicate glass.
Design to allow determination of head/capacity, flow/efficiency curves
and NPSH/flow characteristics. Supplied with a voltmeter, ammeter, pressure
gauges and vacuum controller. Complete with an installation and maintenance
manual and tool kit.
Experimental Capabilities
- Determination of the head/capacity
curve
- Determination of the pump
efficiency/flow curve
- Determination of NPSH
- Observation of cavitation
The experiments use water
as the fluid. Other liquids may also be used to investigate, for example,
the effect of liquid density and viscosity on the pump operation.
The experiments are also
designed to provide training in chemical process equipment operation.
Optional Manuals
The equipment can be supplied
with the following manuals:
Tutor's manual: The
basis of a lecture course on fluid transfer theory and practice. Also
including operating instructions, experiments, typical results and answers
to student questions.
Student manuals provide
the basics of fluid transfer theory and practice with plant operating
instructions.
Experiment booklets provide
step-by-step instructions for performing the experiments, data to be
recorded and questions to be answered.
Additional copies of the
student manuals and experiment booklets can be reordered.
Description
Water held in the vapor disengagement
vessel is pumped around the closed circuit, its flowrate being determined
by the in-line variable area flowmeter. The flowrate is controlled by
the flow control valve and by measuring the differential heat across
the pump at various flowrates, the head capacity curve is constructed.
An ammeter and voltmeter
connected to the electric motor allows, in conjunction with the motor
characteristic curves, the flow/efficiency curve to be constructed.
The vacuum controllers allow
the phenomenon of cavitation to be observed and the pump NPSH to be
determined.
A fully labeled mimic diagram
forms a part of the equipment and ensures simple identification of valves
and recording of plant variables.
No other equipment other
than that for the connection of laboratory services is required.
Options
Either steam or electric
heating.
Electrical System
The electrical system can
be designed to meet your local requirements.
