The invention relates to the technical field of thermal process automatic control teaching equipment, in particular to a thermal process PID temperature control teaching experiment table. The thermalprocess PID temperature control teaching experiment table includes a panel, a hydraulic circulating system, and a PID temperature control system, wherein the hydraulic circulating system for simulating the thermal process and the PID temperature control system are installed on the panel; the hydraulic circulating system for simulating the thermal process includes a circulating pump, a flowmeter, aheating device and a radiator which are connected in sequence; and the PID temperature control system includes a PID temperature control instrument and a pressure regulating module, and the PID temperature control instrument is connected with the heating device through the pressure regulating module. All assemblies of the whole experiment table are fixed to the panel, the structure is compact andsmall, carrying is convenient, the cost us low, the regulating effect is obvious, the requirements of experimental teaching for students to observe and control the control effect of different controlmethods on the controlled temperature are met, and data guarantee is also provided for an electronic experiment report.
Description
technical field [0001] The invention relates to the technical field of thermal process automatic control teaching equipment, in particular to a thermal process PID temperature control teaching experiment platform. Background technique [0002] Most of the existing thermal automation process control experimental devices belong to the field of automatic control. The relevant thermal automatic control process is demonstrated through signal generators, virtual machines and computer simulation experiments. There is no actual thermal process. Some experimental devices have introduced Small boilers (water heaters), water tanks, heat exchange coils and other actual thermal components construct a thermal cycle process, but due to the high cost, the need to rely on computers to complete the experimental process, and the large footprint, the promotion is limited. Its diverse functions It also exceeds the needs of general teaching. Even if it is purchased and used, the quantity is limit...
