EF-4.3 – KINEMATICS – DRIVE SYSTEMS

The EF-4.3 Drive Systems experiments kit introduces students to various types of belt, chain, and shaft drive systems.

2 trays supplied with EF-4.3

DESCRIPTION

The Engineering Fundamentals range enables students to gain an understanding of the principles of engineering by the process of learning via experimentation.

The EF-4.3 Drive Systems experiments kit introduces students to various types of belt, chain, and shaft drive systems.

Belt and chain drive experiments are included to demonstrate the characteristics of different belt and chain systems with multiple velocity ratios. The efficiency can be calculated for varying loads for both the different velocity ratios and the different belt and chain systems allowing comparisons between the different systems to be observed. Experiments are also included to demonstrate the effect of belt tension and the effect of pulley lap.

Experiments in universal couplings define how they should be set up to ensure that the rotational velocity from the input is seen at the output. The angle of each universal joint and the orientation relative to each other will be tested to see which setup will give uniform angular transmission.

FM51 – SERIES AND PARALLEL PUMPS DEMONSTRATION

Two motor-driven centrifugal pumps mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation.

DESCRIPTION

Two motor-driven centrifugal pumps mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation. The pumps can be configured for single pump operation, two pumps in parallel or two pumps in series by using manually operated ball valves. Similarly, manual valves are used to control the flow and facilitate the study of suction effects, including demonstration of air release.

In parallel operation the two pumps draw from a shared inlet pipe of a wider diameter than the pump inlet, reflecting a typical industrial configuration of parallel pumping.

Each pump has impellers that can be easily accessed and replaced without tools. The FM51 is delivered with three impellers in total, one with forward curved blades and two with backward curved blades, allowing the students to investigate the effects of impeller characteristics.

Electronic sensors measure the pump outlet pressure of each pump, the shared pump inlet pressure, the flow rate and the water temperature.

The pump speed of the first pump is accurately controlled by an advanced electronic inverter within the IFD7 (an essential accessory) and can be varied over the full range.

The inverter also calculates the torque produced at the motor drive shaft, allowing the power used by the pump to be derived. The second pump runs at inherent motor speed.

This combination of control facilities allows a wide range of different configurations to be investigated.

CM20 – SINGLE-CYLINDER COMBUSTION ENGINE

The Armfield CM20 Single Cylinder Engine Range provides a self-contained engine test rig that enables students to investigate a range of engine performance characteristics.

The unit is designed to be linked to the user’s computer or touch screen, linked to Armfield’s supplied software with sophisticated control and data acquisition.

DESCRIPTION

The Armfield CM20 Single Cylinder Engine Range provides a self-contained engine test rig that enables students to investigate a range of engine performance characteristics.

The unit is designed to be linked to the user’s computer or touch screen, linked to Armfield’s supplied software with sophisticated control and data acquisition.

The Armfield CM20 is a self-contained integrated, single-cylinder engine, dynamometer and instrumentation system, based on a range of gasoline and diesel industrial engines.

The CM20 utilises an eddy-current dynamometer to provide a variable load on the engine, enabling the characteristic power and torque curves to be reproduced in the laboratory dependent upon which sensor options are ordered. This multi-purpose test rig is designed to accept a series of Armfield gasoline and diesel engines available separately. The system comes complete with instrumentation, including rpm measurement, torque (from which power can be calculated), airflow and exhaust temperature. Other optional sensors can be purchased to further enhance the teaching capabilities of the CM20 including cylinder pressure sensors and fuel consumption.

The whole system is designed to be linked to a computer using the software provided. This provides real-time monitoring of the various sensors, with a wide range of data logging and graphical display options. Both the dynamometer and throttle can be controlled electronically, which makes installation into a closed test cell straightforward, and enables remote operation.

The CM20 should be installed in a well ventilated area with exhaust gas extraction facilities. The unit is supplied on wheels for ease of movement; these can be removed and the unit bolted to the floor for permanent installation.

Apart from the master on/off switch, everything can be controlled remotely, enabling the engine to be installed in a dedicated test cell and operated from outside the cell.

RA3 – COMPUTER CONTROLLED RECIRCULATING AIR CONDITIONING UNIT

RA3 is a floor standing unit, with all the features of the RA2 plus a recirculation feature via an enclosed chamber. Some of the air exiting the chamber can be recycled back into the conditioning duct.

DESCRIPTION

RA3 is a floor standing unit, with all the features of the RA2 plus a recirculation feature via an enclosed chamber. Some of the air exiting the chamber can be recycled back into the conditioning duct.

The RA3 is a floor standing, self contained unit comprising a square ventilation duct mounted on a mild steel frame. The duct has a clear acrylic section allowing visibility of all components.

The air out of the duct is passed into a chamber to demonstrate climate control. The exit duct from the chamber is fitted with adjustable vents allowing some of the air to be recirculated back to the duct inlet.

Additional sensors measure the temperature and RH at the chamber outlet and after the recirculated air is mixed with the inlet air as well as the flow rate of the recirculated air.

Pressure gauges and temperature sensors allow the refrigerant temperature change across the condenser and evaporator to be established.

The refrigerant flow rate is measured using a variable area flow-meter.
