The Sedimentation Tank allows to study the hydraulic and efficiency characteristics of the sedimentation by means of a special rectangular section tank. The unit is fitted with an ink injecting device in order to visualize the flow lines obtained in the settling tank. The sludge, which is kept in suspension in the preparation tank by a stirrer, is sent to the sedimentation tank by a variable speed peristaltic pump together with a water flow rate adjusted through a manual valve. The group is supplied with manuals which describe all parts of the unit, the installation and utilization procedures, as well as many exercises with the relative results.

Flash Drum Trainer With PLC trainer provides the student the opportunity to gain real operating experience focusing on both the process of flash separation and control strategy. The Flash Drum Trainer With PLC is a bench-scale plant that demonstrates continuous separation of a binary mixture of water saturated with carbon dioxide. The process has instrumentation to provide for control of operating flow, temperature, level and pressure.
Function of Flash Drum Trainer With PLC
Flash Drum Trainer With PLC trainer separates a water CO2 mixture in a see-through, industrial glass vessel. The trainer is equipped with process measurement and control devices. The separation of volatile gasses dissolved in a liquid and recovery of the components usually involves a flash drum. Flash drum operations are found throughout the petroleum, petrochemical and numerous other industries. The entire trainer is controlled from a programmable logic controller computer interface (PLC). It has one each of temperature, pressure, level and flow controls.
2 modules form basis for over 9 fully documented experiments
144MHz VHF FM transceiver trainer
Includes experiment and instructor's manual.
A simple deadweight tester with weights and a bourdon tube pressure gauge with a clear front allowing the mechanism to be viewed. The unit has an optional pressure transducer available allowing the concept of electronic representation of pressure to be investigated. Unique design allows standard Newton weights to be used; hence reinforcing the student understanding of pressure being Force / Unit Area.

Dynamic friction is differentiated into sliding, rolling and spinning friction. In dynamic friction, there is relative translation between the two bodies. Rolling friction occurs when two bodies roll on each other without sliding. In bearing and drive technology, dynamic friction occurs at the sliding and rolling points, which leads to power losses in the technical systems. Rolling friction is therefore a combination of rolling and dynamic friction. In rolling friction, the rolling motion is superposed with a smaller sliding friction, known as slip.
Features:
Frictional forces between two rolling friction wheels
Use of different lubricants possible
How slip affects the frictional force
Learning Objectives And Experiments:
Determine the frictional forces as a function of load, lubrication and operating speed
How slip affects the frictional force
Together with the drive unit
Determine the coefficients of friction.
This auxiliary pump is intended to be used inconjunction with the basic Hydraulics Bench. This accessory comprises a variable speed pumpassembly and independent discharge manifold interconnected by flexible tubingwith quick release connectors. The pump speed is varied by an inverter drive. An independent discharge manifold incorporates apressure gauge and flow control valve prior to a discharge pipe with diffuser. A compound pressure gauge is mounted on the pump inlet and a pressuregauge is mounted on the pump outlet. Themotor speed, output voltage and motor current can be monitored on the inverterdisplay. The auxiliary pump is mounted on a support plinthdesigned to be positioned on the floor besides the hydraulics bench, adjustable feet allowing levelling.

The tank is manufactured from glass reinforced plastic and all components in contact with water are of non-corroding materials.
A self contained recirculating water tank for flow visualisation and mobile bed studies.
All controls are housed in a portable console which includes a flexible cable and water safe connectors.
Fifteen models and accessories are included as standard and a sheet of coloured glass allows rapid changeover from mobile bed to flow visualisation mode.
The working section has minimum dimensions of 2m(4m) x 610mm and the flow range is 0-3.5 litres/sec.
The DC motors are used in a wide variety of industrial drives, such as robots, machine tools, oil drilling rigs, mining, automotive systems, etc. On the other hand, DC generators are still in use in some power generatingplants. The real difference between DC motor and DC generator is the directionof power flow. All the DC machines have a reversible behavior: they aremotors up to a frequency that is characteristic of the construction parametersand is said synchronism frequency, beyond which they behave as generators. The electric machines bench has been designed to satisfy thefollowing basic requirements:
The plan activities
The economic advantage
The number of groups of students who must worksimultaneously
Their speed can beeasily adjusted in very fine increments ranging from standstill to rated speedand even above and their construction is made rather complex than their AC counterparts by the fact that they need a commutator, which reverses thedirection of current and fluxes to produce a net torque. The DC machines are driven from a DC power supply and theyare the most versatile of all rotating electrical machines.

The unit provides different configurations of control gears, which serve as an introduction togear engineering. The unit focuses in particular on the practical assembly ofgear components. The exercise system can be used to configure six differentgears in various combinations. Control gears are also known as variable or change gears.They are characterised by the fact that the speed is transferred differentlyvia various pairs of gear wheels. The most famous example is the transmissionin a car, which has one pair of gear wheels for each gear. The setup of the components is flexible so thatyou can configure your own ideas and try out different gears. The unit is driven by a handcrank. A solid frame made of square steel tubes and various bearings ensuressufficient accuracy to be able to set precise tooth interlocking. Allcomponents of the exercise system are ready at hand and securely housed in astorage system. Individual activities such as understanding the task and reading the drawing, assemblingthe components, adjusting, calibrating and checking the gear, and performingcalculations are performed one after the other.
Features:
Flexible and robust assembly kit for continuing mechanicalgear engineering.
Quick and simple assembly.
Uses industrial components to represent the real worldaccurately.
A dead-time residence coil can also be attached to the exit of the last reactor in the series.
A self-contained bench mounted small scale unit fitted with three continuous stirred reactors in series which are fed from two 5 litre tanks. Each reactor is fitted with a conductivity probe.
There are two independent, variable speed feed pumps.
Ideal for student experiments, laboratory demonstrations or project work, Engine Cycle Analyser enables students to investigate a variety of engine performance characteristics. The equipment is primarily for use with engine test sets and engines but it can also be used with other engines fitted with compatible cylinder head transducers and crank angle encoders. The versatile equipment consists of both hardware and software specially designed for educational use. It enables students to investigate the relationship between crank angle or volume and the cylinder pressure in an internal combustion engine. The equipment consists of a hardware unit with connectors and leads,plus Windows based data acquisition and analysis software. The hardware consists of a microprocessor-based signal conditioning unit with high-speed PC interface, housed in a rugged, protective enclosure. The cylinder pressure input includes a precision charge amplifier with a digital thumb-wheel for calibration. As well as crank angle position,the signal from the Crank Angle Encoder is also used to determine engine speed. It accepts and conditions signals from the Cylinder Head Pressure Transducer and Crank Angle Encoder available separately.
