Novel water temperature control method matched with starting of unit

The invention belongs to the technical field of uranium concentration engineering machinery auxiliary systems, and particularly relates to a novel water temperature control method for starting a matched unit. A pipe A and a pipe B in a main engine cooling water system are independently operated, the pipe A serves as a pipeline for providing the temperature of 24-30 DEG C of preheated water for impact, trial start and cycle rising, and the pipe B serves as a pipeline for providing the temperature of 11-15 DEG C of main engine cooling water. The objective of water supply temperature optimization control of the water auxiliary system in the field of uranium concentration engineering machinery auxiliary systems is achieved for the first time. Through optimization and adjustment of the water temperature control method, the unit can achieve the purposes of providing the water temperature of 62 +/-1 DEG C for vacuum drying, normal impact, trial start, the water temperature of 24-30 DEG C for cycle rising and the wat
