The utility model has the advantages of reasonable structural design, opening and visual performance, has flexible contact and match between test effects and test objects, is beneficial for the selection of control objects and is beneficial for the form of the complicated test system.
Description
Technical field
The utility model relates to a kind of process control objective system experimental provision, is specially adapted to the experimental teaching of institution of higher learning's " Theory of Automatic Control ", " process control ", " instrument and meter for automation " and courses such as " sensor and switch technologies ".
Background technology
Theory and practice seriously disconnects in the teaching of existing institution of higher learning, and be difficult to find suitable automation class teaching instrument and equipment to satisfy the needs of experimental teaching, perhaps the device structure of only a few manufacturer production is too simple and crude, can not satisfy the needs of complex control system experiment, more can not simulating reality in than the situation of long pipeline.
Summary of the invention
Technical problem to be solved in the utility model provide contact and collocation between a kind of reasonable in design, opening, directly perceived, the experiment effect experimental subjects flexibly, help controlling object selection, help the process control objective system experimental provision of the composition of complicated experimental system.
It is this process control objective system experimental provision that the utility model solves the problems of the technologies described above the technical scheme that is adopted, it is made up of reserve tank, upper water box, lower header, boiler, water pump, electric control valve, turbo flow meter, liquid level sensor and solenoid valve, and its design feature is: be provided with coil pipe between boiler, water pump.
Also be provided with middle water tank between upper water box described in the utility model and the lower header.
The utility model is compared with prior art and is had the following advantages and effect: 1, owing to be provided with coil pipe, increased the complicacy of whole device, made process control more near truth.2, owing to increased a water tank, make technological parameter complicated more, changeability is stronger.3, owing to, can make the student more clearly understand the technological process of production of industry spot by open, objective system structure intuitively.The power system design of two cover difference in functionalitys had both made experiment effect more obvious, can take into full account the reasonable arrangement of teachers' instruction time again, had increased a water tank and coil pipe, made process control complicated more, more near the situation in the real industry.Standard, the signaling interface of opening are for this experimental subjects subsequent control expanded function is laid a good foundation.4 and firm stainless steel frame structure and exquisite organic glass cistern system structure, both guaranteed serviceable life of experimental provision also to have increased breadboard decorative colour.5, contact and collocation are very flexible between each model experiment object, help the selection of controlling object and the composition of complicated experimental system.6, controlled variable has been included flow, pressure, liquid level, temperature four big thermal parameters.7, existing topworks in the actuator has Electric Traction class actuator again.8, system does the step disturbance except the setting value that changes regulator, also can make various disturbances by solenoid valve and manual manipulation valve in object.9, controlled variable can be with developing into multiple regulating loop under different dynamic source, different actuator, the different technology circuit, is beneficial to discuss, the quality of more various regulation schemes.10, design during this system in line with through engineering approaches, parametrization, modernization, opening, comprehensive principle, experimental subjects has adopted that a lot of industry spot are commonly used to be detected and actuator devices.Objective system also leaves expansion interface, and expansion interface is convenient to the control system secondary development, so that carry out DCS control, and remote data acquisition control, computer control, PLC controls exploitation.
