Research on Control Method of Temperature Distribution of Rotor Sidewall of Rotating Machinery.

By investigating the existing temperature control technology and analyzing the technical characteristics of temperature controlling of the rotor sidewall of rotating machinery, this paper establishes a single-channel temperature closed-loop control model. Furthermore, a multi-channel temperature control structure is designed and related control strategies are formulated. In order to carry out the verification experiment, this paper builds a multi-channel temperature control experimental platform for the rotor sidewall of rotating machinery. The platform adopts the "LabVIEW + PID regulator" architecture to achieve active control of temperature distribution of the rotor sidewall. The experiment proves that the architecture of the experimental platform is indeed feasible, the temperature control precision is high, and it is safe and reliable. Therefore, the method for controlling the temperature distribution of the rotor sidewall of rotating machinery proposed in this paper is also indeed feasible. This work lays an important foundation for studying the relationship between the temperature distribution of the rotor sidewall of rotating machinery and its performance.
