This article introduce a kind of energy-saving control method and implementation for a tower pump in industrial cooling water system (hot tub→ up tower pump→ cooling tower→ cold pool). Under the conditions without changing the original industrial cooling water’s normal operating, the method of temperature control liquid-level under the protection of pressure to regulate and control the energy-saving process of cooling water on tower pump was used. According to the hot tub’s actual temperature and cold pool’s temperature which has process requirements can automatically regulate the hot tub’s liquid height or the height difference between hot tub and cold pool. It can finally automatically control the natural flow rate of the connected overflow hole or connecting pipe, thereby reducing the pump flow rate on tower to ensure the purpose of siginificant energy-saving on the basis of process demand. The comprehensive energy-saving rate can be 40% to 60% or more.
