Embodiment Construction

[0019] The present invention will be described in detail below with reference to the embodiments shown in the drawings.

[0020] This process control experimental device is an integrated type, using a transparent water tank as the basic unit to simulate the dynamic characteristics of the controlled object and the measuring transmitter. There are no pipes and valves between the water tanks. The simulation principle is the same as the computer digital simulation mechanism, but it is a physical simulation method realized by fluid based on a mathematical model. The liquid resistance and liquid capacity of each tank constitute a first-order resistance-capacitance link, the flow resistance can be changed as needed, and the capacity coefficient can be adjusted. Multi-level system transfer functions are used to simulate multiple tanks, and the integration level ranges from two to many. The system time constant ranges from a few tenths of a second to several minutes or tens of minutes, w...

Abstract

The invention discloses an integrated experimental device for controlling a dynamic process of a flow industry, and relates to an experimental control device. The device consists of more than two resistance-capacitance water tanks, and a pipeline-free and valve-free integration mode is used for forming the experimental device for simulating dynamic characteristics of an object. A plurality of control system modes are configured for test. A controlled object of the experimental device is formed by integrating basic units which are resistance-capacitance links without pipelines or valves. The fluidic resistance of a throttling hole is regulated in a threaded seat cover way, and is changed from 0 to infinite to simulate a plurality of linear or nonlinear dynamic characteristics. The water tanks are provided with measurement transmitters respectively, a field indication rotor flow meter, a throttling hole plate, a control valve and a circulation water pump are arranged in four paths of water inlet pipelines respectively, and a pressure meter is arranged at an outlet of the water pump. The device can be used for a process control simulation experiment in flow processes of large chemical production devices, equipment and machines, fluid production devices, equipment and machines and the like, and is applied to the automatic teaching and scientific researches of colleges, scientific research institutions, training institutions, factories and the like as well as teaching.

Description

Technical field [0001] The invention relates to an experimental device, in particular to an integrated process industry dynamic process control experimental device. Background technique [0002] At present, some of the controlled objects of process control experimental devices use simulation methods that resemble the actual industrial objects according to their appearance, simplify and shrink the structure, such as distillation towers, neutralization reactors, heat exchangers and electric boilers. Its advantage is its intuitive image. The stainless steel material is beautiful and beautiful. The five parameters (temperature, pressure, flow, liquid level, PH) are used to name various control system experiments. It seems very real, but it turns out that it is difficult to simulate the process more comprehensively. The dynamic characteristics of various towers, kettles, furnaces, kilns, vessels and machines in the industry are very limited and lack the flexibility of simulation. The...
