Product Description
Pump Test Set for Fluid Mechanics Engineering Lab Equipments
Technical Specification
To demonstrate the operating characteristics (headflow curves and efficiency) of a series of different types of pumps, each having a broadly similar input power.
The rig should accommodate both rotodynamic and positive displacement pumps, and should supply with the most common example of each type as standard (i.e. a centrifugal pump and a gear pump).
A range of other pump types should be available as accessories, (including axial, turbine, flexible impellor, diaphragm and plunger, plus a second centrifugal pump for series/parallel demonstrations).
Up to four pumps could be accommodated within the rig simultaneously for use within a single laboratory period, and each should be able to run without disconnecting any pipework or connections. Further pumps can also be interchanged straightforwardly.
As an option the unit should be able to be fitted with
two identical centrifugal pumps to allow simple series/parallel pump configurations to be demonstrated.
The equipment comprises a water reservoir, and five pump positions, (four active). Each pump position uses pipework and sensors optimised to the type of pumps it is intended for.
Each pump accessory should come on its own baseplate, assembled complete with all pipes, valves and fittings to allow it to be easily fitted
Other specifications:
a. A self contained multi-pump test rig, containing all the services and instrumentation for determining the characteristic curves of different pumps at different speeds
b. Should contains five different pump positions (4 active)
c. Centrifugal pump and gear pump should be supplied as standard.
d. Axial pump, flexible impellor pump, turbine pump, diaphragm pump, piston pump and a second centrifugal pump and all should be available as accessories e. Series/parallel pump demonstrationsshould be able to be performed with the second centrifugal pump option
f. Control valve should be incorporated upstream of each pump (except axial pump) to demonstrate the effect of suction loss on performance
g. Electronic torque measurement using a state of the art sensorless vector drive
h. Electronic measurement of flow, pressure head and suction
i. Optional volumetric flow measurement system for reciprocating pump
j. Optional data logging and educational software.
The following should be the demonstration capabilities
a. Determining the performance of different types of pumps at constant speed by producing a set of characteristic curves For rotodynamic pumps:
Pressure head v flow
Power absorbed v flow
Pump efficiency v flow For positive displacement pumps:
