  • Patent number: 11953235
    Abstract: A low-heat-loss operation method of a line-focusing heat collection system and the line-focusing heat collection system are provided. The method includes the following steps. Solar energy is utilized to preheat a collector tube in an empty tube state, so that the collector tube is in a preheating mode. After a set preheating temperature is reached, a heat transfer working medium is injected into the collector tube. In the injection process of the heat transfer working medium, an injection section of the collector tube is converted into a focusing mode from a preheating mode. After heat collection is finished, the circulation of the heat transfer working medium is stopped, and the focusing mode of the collector tube is kept. In the drainage process of the heat transfer working medium, an emptying section of the collector tube is converted into a light heat-tracing mode from a focusing mode.

  • Patent number: 11913512
    Abstract: A vibration suppression method for a servo motor and a load multistage drive system is provided. For a number N of fixed vibration frequencies and one vibration frequency varying with a load position existing in a multistage drive mechanism, a number of N+1 vibration suppression filters are adopted, and each filter is configured to eliminate a corresponding vibration frequency. Fixed vibration frequencies and a vibration frequency varying with a load position in a multistage drive system are measured by using an offline method, and the varied vibration frequencies are made into a two-dimensional table related to the load positions. The fixed vibration frequencies are eliminated by using fixed-frequency parameter vibration suppression filters; and the varied vibration frequencies are eliminated by using a variable-frequency parameter vibration suppression filter, and the vibration frequencies are obtained in real time according to the load positions and the two-dimensional table.
