Abstract
The invention relates to the technical field of heat supply networks, and discloses a heat supply adjusting method and system. The method comprises the steps of obtaining a noise value and a vibration value of the heat exchanger and substituting into a preset formula for calculation to obtain a comprehensive index; judging whether the comprehensive index is greater than a preset value; if the comprehensive index is larger than the preset value, the opening degree of a bypass adjusting valve is adjusted according to the comprehensive index, and the bypass adjusting valve is located on a bypass pipeline communicating a circulating water inlet pipeline and a circulating water outlet pipeline of the heat exchanger. The bypass pipeline and the bypass adjusting valve are arranged between the circulating water inlet pipeline and the circulating water outlet pipeline, and the opening degree of the bypass adjusting valve is adjusted through the adjusting method in the technical scheme, so that the circulating water inlet amount is automatically adjusted, the circulating water inlet temperature is adjusted, the internal pressure of the heat exchanger is guaranteed, and the heat exchange efficiency is improved. The problems of vibration and noise caused by overlarge pressure difference between the steam inlet pressure and the internal pressure of the heat exchanger are avoided, the service life of the heat exchanger is prolonged, and the operation safety of a heat supply network system is improved.
