Introduction
The reciprocating air compressor provides a useful introduction to both heat engine theory and fundamental thermodynamic analysis. The measured parameters also give students experience of a wide range of instruments and measurement techniques.
The Hilton Single Stage Compressor Test Unit F860 will provide interesting and instructive experimental work for all students, and will be of particular interest to those studying:
● Thermodynamics
● Energy Conservation
● Mechanical Engineering
● Plant and Process Engineering
● Automotive Engineering
● Fluid Mechanics
Experimental Capabilities
● Measurement of intake and delivery pressure
● Measurement of air flow rate.
● Measurement of all relevant system temperatures
● Determination of the volumetric and isothermal efficiency.
● Measurement of drive power and electric motor shaft power.
Description
A bench mounted unit with a belt driven reciprocating air compressor.
The drive motor is mounted in bearings and allows the torque required to drive the compressor to be measured using an integral balance.
With the measured torque and motor speed the shaft power required to drive the compressor may be determined. Compressor speed is measured through the fixed pulley ratio between the drive motor and compressor.
Panel mounted meters allow the motor electrical input to be compared to the measured shaft power.
The intake air passes through an orifice for flow measurement to a vessel that reduces intake pulsations and allows various intake conditions to be established. The intake and delivery pressures are indicated on dial gauges and all of the relevant system temperatures are recorded by thermocouple sensors connected to multiple selector switches and a digital temperature indicator.
The flow measurement orifice is connected to a panel mounted manometer to allow differential pressure measurement.
Air is delivered to a receiver fitted with a high pressure cut out and relief valve for operator safety. A throttle valve allows discharge pressure to be controlled and adjusted.
Optional Data Acquisition Upgrade
An optional computerised data acquisition upgrade FC861A is available to enable all relevant system parameters to be automatically recorded on a PC for further analysis and display. Data may also be transferred to spreadsheet format for complex analysis and calculation. This upgrade can be factory fitted prior to delivery or supplied later as a user installed upgrade.
Specification
A bench mounted, belt driven, single stage reciprocating air compressor with a motor dynamometer allowing measurement of the motor shaft power.
An intake vessel reduces intake air pulsations and a high pressure air receiver is connected to the compressor discharge.
Intake and discharge air pressures are measured together with the air flow rate, motor drive speed and torque.
Integral duplex thermocouples record all relevant system temperatures and are connected to a multi-way selector switch and digital temperature indicator.
An optional computerised data acquisition upgrade is available that allows all relevant system parameters to be automatically recorded on a PC.
The unit is supplied with a detailed experimental operating and maintenance manual giving example experimental results and sample calculations.
Accessories and spares for two years normal operation together with a full two year warranty are also included as standard.
