Boiler Heating Batching Process Control System- Engineering Lab Training Systems.
Technical Description
This complete and comprehensively
equipped laboratory test stand offers numerous possible experiments from
the areas of process control. It contains a total of four different
control loops with local digital, industrial controllers. In addition,
it is also possible to realise two cascade control systems. A further
controller is provided for cascade control. The controllers can be
configured independently of each other as required and can be operated
both individually and simultaneously. They all have serial interfaces.
The experimental section is formed by a closed water circuit. Water is
pumped from a supply tank through a pipe system by a 1.1 kW centrifugal
pump. A pneumatically actuated control valve included in this circuit
makes allows to change the flow rate and thus to control the circuit.
The level can be controlled in two stainless steel tanks of differing
capacity. For this purpose a bypass mounted on the tank feed is
controlled by a further pneumatic valve. The two tanks can be connected
together to change the characteristic of the control loop. An
electronically adjustable 7.5 kW heater enables to heat the water as
part of a temperature control system. During overheating, a siren and an
alarm lamp will be activated. The system water in the circuit can be
cooled by a heat exchanger. Fresh water from an external water supply is
used as cooling liquid. The pressure control system uses external
compressed air at one of the two tanks. The test stand is built using
only industrial standard components to increase its relevance to
practice. The support made of steel tubes is fitted with laboratory
castors and can thus be easily moved around.
Software for the process visualisation and Profibus card are available as an accessory.
