A self-contained, fl oor-standing mobile unit that includes a small comperssor and instrumentation. It allows students to study and perform tests on a centrifugal compressor, to understand how it works and calulate its performance.
Key features
• Centrifugal compressor, mounted in a mobile frame with full instrumentation
• Part of TecQuipment’s Modular Fluid Power range that connects with the Universal Dynamometer (MFP100) as a common motive power source for a cost-eff ective solution
• Allows students to study and test a common type of rotodynamic machine, safely and at a realistic scale
• Pressure and temperature measurements at key points in the system
• Connection plate with schematic diagram clearly shows the arrangement of the module
• Fully variable speed, for a range of test results
• Includes digital displays of pressure and temperature
• Connects to TecQuipment’s optional Versatile Data Acquisition System (VDAS®)
Description
For use with the Universal Dynamometer (MFP100), the Centrifugal Compressor Module is part of TecQuipment’s Modular Fluid Power range. This range examines and explains fl uid power machines. The Centrifugal Compressor Module is ideal for student experiments, demonstrations and projects.
Centrifugal compressors are common machines, used for forced ventilation in applications that need a good volume of air at a reasonable pressure - for example: forced ventilation and cooling systems.
The module consists of a compressor and instrumentation, all mounted on a robust, mobile trolley for ease of use. The module is for use with and driven by TecQuipment’s Universal Dynamometer (refer to MFP100 datasheet). The Universal Dynamometer measures the speed, torque and power absorbed by the compressor. Speed is fully variable up to the maximum allowable for the compressor. Air enters the compressor through a shaped nozzle, used to measure the airfl ow rate. The air then moves past a hand operated delivery valve and out to atmosphere. The delivery valve controls the airfl ow rate (and therefore delivery pressure).
Electronic transducers measure the inlet pressure, delivery pressure, nozzle diff erential pressure (fl ow rate) and the atmospheric (barometric) pressure. Thermocouples measure inlet, outlet and ambient temperatures. Digital displays show all the readings.
For quick and reliable tests, TecQuipment can supply the optional VDAS® (Versatile Data Acquisition System). VDAS® gives accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer. The computer is not supplied.
