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.

Permeability is recognized as being the most important parameter in assessing concrete durability. The depth test is performed by drilling a hole 10 mm diameter x 40 mm deep, and plugged with a silicone rubber plug. The ingress of air and moisture into the concrete can cause corrosion of the steel reinforcement and lead to a deterioration in concrete strength. An hypodermic needle is passed into the stopper; the water permeability test is performed by measuring the time of absorption needed by the water introduced into the void by pressure. Therefore, a measure of the ease of movement of liquids and gases through the surface layer of the concrete is a better method of assessing the soundness and expected life of concrete than strength alone. Surface permeability tests can be carried out by clamping a stainless. For the air permeability test, a vacuum pressure is created in the void, and the time needed to rise this pressure is measured.

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.
The Radial Heat Conduction accessories have been designed todemonstrate the application of the Fourier rate equation to simple steady-stateconduction radially through the wall of a tube.
Hardware Description:
The accessory comprises a soliddisk of material, which is heated at the centre and cooled at the periphery tocreate a radial temperature difference with corresponding radial flow of heatby conduction.
Six K-type thermocouples arepositioned at different radii in the heated disk to indicate the temperaturegradient from the central heated core to the periphery of the disk.
The arrangement, using a solid metal disk with temperature measurementsat different radii and heat flow radially outward from the centre to theperiphery, enables the temperature distribution and flow of heat by radialconduction to be investigated.
The heater power and the cooling water flow rate are controlled via,either from the front panel or from the computer software. These are controlledmanually.
A control valve permits the flowof cooling water to be varied, if required, over the operating range of 0-1.5l/min.
The cooling water flow rate ismeasured by a turbine type flow sensor .
An optional cooling water flowrate sensor Set 2 is available upon request for the connecting directly intothe service unit.
The radial distance between eachthermocouple in the disk is 10mm.
Quick-release connectionsfacilitate rapid connection of the cooling tube to a cold water supply. Apressure regulator is incorporated to minimise the effect of fluctuations inthe supply pressure.
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 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.
