Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature control, in particular to an automatic constant temperature control device for circulating water. Background Art

[0002] During the transportation process of purified water in pharmaceutical factories, the water temperature will continue to rise due to uneven water use. The main reason for the increase in water temperature is that when the purified water circulates in the pipeline, the water will rub against the pipe wall, causing the water temperature to rise. The purified water delivery pump will generate heat at the pump head during operation, and the purified water will absorb the heat of the pump head, causing the water temperature to rise. Many products have relatively high requirements for water temperature, so it is necessary to control the circulating water temperature to ensure a constant water temperature.

Therefore, under different circumstances, the temperature-adjusted liquid washed in the double tube sheet heat exchanger can be heated or cooled to maintain it within a predetermined temperature range. However, the water entering the control device is easily mixed with the discharged water during the process of controlling the water temperature, affecting the stability of the water temperature.
