A water pump which is controlled by an adjustable speed motor is arranged between the connecting pipelines, and the output pipeline of the water pump is provided with an effusion meter; a valve used for automatic control is an electromagnetic valve. The procedure control experimental apparatus can do better pressure experiment than the top and bottom water head at present as the pressure tank is assembled in the controlled object, and the volume of the controlled object is greatly reduced so as to achieve the miniaturization of the controlled object and the intellectualized control experiment. In addition, the controlled object can be disassembled and assembled conveniently, and a plurality of control systems can be composed flexibly. The utility model is convenient for engineering practical training, diploma design and scientific research; various failures can be arranged in the controlled object to allow students to do practical training by excluding the failures; the connection mode between the controlled object and a control console can be designed and made by the students, which greatly enhances the operation ability of the students; the flow quantity is adjusted by regulating the revolting speed of an electric motor, the adjusting precision is enhanced, the volume of the controlled object is reduced, and thereby, the controlled object can be arranged on a trolley, and the utility model is flexible and convenient.
Description
Technical field
The utility model relates to the instructional device of a kind of student of being used for to process control study, particularly a kind of process control device.
Technical background
At present, in the experimental provision of " process control ", pressure experiment adopts upper and lower water-head to produce, and routine is all wanted about 2 meters, makes the controlling object volume and weight very huge, is not easy to experimental implementation; In flow regulation, adopt huge electric control valve controlling opening of valve size to realize, make the volume and weight of controlling object huge equally, and degree of regulation is poor, makes whole process control device seem heavy and huge, and both inconvenience had been moved, also wasting space takies, and influence degree of regulation, and the water tank volume is bigger, and also inconvenience is moved.
The utility model content
The purpose of this utility model is that a kind of controlling object miniaturization, operation, easy accessibility, a kind of process control device that experimental precision is high of making is provided for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of process control device that the utility model is designed, it mainly comprises water tank and connecting tube, at least one water tank links to each other with the head tank pipeline, interconnect by connecting tube between each water tank, thereby make the differential pressure experiment not need very high liquid level difference to obtain, just can realize by the air pressure of head tank.
In order to dwindle the volume of experimental provision, the adjusting of flow is not controlled by huge automatic regulating valve, between the connecting tube of water tank, be provided with water pump, on the output channel of water pump, be provided with flowmeter, by the direct controlling liquid flow of buncher with buncher control.
For make valve can automatic switch control, and reduce the space hold of device, the valve that is used for control automatically is a solenoid valve.
In addition, in order to obtain temperature experiment, in water tank, have in the water tank to be provided with well heater and semiconductor cooling device.
Process control device described in the utility model, owing to disposed head tank in the controlling object, water-head is far better up and down than adopting at present to do pressure experiment, and the controlling object volume is greatly reduced, and realizes the controlling object miniaturization, is convenient to intelligent control experiment.In addition, the controlling object easy accessibility can be formed the various control system flexibly, is convenient to the usefulness of engineering experimental exercising, graduation project and scientific research; In the controlling object various faults can be set, allow the student carry out real training by fixing a breakdown; Connected mode can allow student oneself design between controlling object and the control desk, and oneself is made, and improves students ' practical ability greatly; Adopt the adjusting motor speed to regulate flow, improved degree of regulation, also dwindled the volume of controlling object, controlling object can be contained on the small handcart thus, flexible.
Process control device described in the utility model can cover the content of courses of " process control " course, make the student understand the principle and the characteristics of modern process control by experiment, in-depth and replenish the content of " process control " Theory Course improves ability and the practical operative ability of university student in common procedure parameter controlling party surface analysis problem such as " temperature, flow, pressure and liquid level ".The process control device that utilizes the utility model to provide can be used as single loop control experiment, single loop flow control experiment, the experiment of single loop pressure control, single water tank and two high water tank control experiments in simple control system experiment; The tandem that can be used as pressure and flow in the complex control system experiment is controlled the even control experiment of feedforward control experiment, flow and the liquid level of experiment, flow and temperature, the experiment of temperature Smith's Prediction Control; In the advanced control system experiment, can be used as PREDICTIVE CONTROL or internal model control experiment, the fuzzy control experiment of flow and the PID and the internal model control experiment of network control liquid level of liquid level.

Fig. 1 is that the utility model structure is formed synoptic diagram.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment:
As shown in Figure 1, a kind of process control device that present embodiment is described, it mainly comprises water tank 1,2,3 and connecting tube, water tank 1 links to each other with head tank 4 pipelines, interconnect by connecting tube between each water tank, between the connecting tube of water tank 3 and water tank 1, be provided with water pump 5, on the output channel of water pump 5, be provided with flowmeter 6 with buncher control, at this, the valve that is used for control automatically is a solenoid valve.In order to obtain temperature experiment, in water tank 3, be provided with well heater and semiconductor cooling device and temperature sensor 11; Be provided with pressure transducer 7 on head tank 4, be provided with liquid level sensor 8,9 on water tank 1,2, the output line of each sensor can be connected in the control box 10 voluntarily according to the required different experiment of student.At this, water pump 5 is hearts of whole process control device, is the topworks of flow, pressure, liquid level control; The regulating device that well heater provides energy, solenoid valve to can be used as flow for temperature control is to replace common electric control valve; Liquid level sensor 8,9 can adopt ultrasonic liquid level sensor, to be different from the pressure-detecting device based on indirect measuring principle, makes classmates can understand the meaning of direct measurement.
