The circulating water pump is used as large auxiliary equipment of the thermal power station, and during the operation of the unit, the circulating water is provided for the condenser to carry the steam heat of the low-pressure cylinder exhaust steam, so that the steam is condensed into water, and the vacuum of the condenser is maintained. When the circulating water pump is in operation, continuous and stable cooling water is required to take away heat of the self bearing and the coil, so that the circulating water pump can be ensured to safely and stably operate. At present, two paths of cooling water of the circulating water pump are designed: one path is taken from an outlet of the circulating water pump, namely, in the operation stage of the circulating water pump, cooling water is provided for the circulating water pump through the outlet of the circulating water pump; the other path is taken from the industrial water pump, namely, when the circulating water pump is not started to be in a standby state, the industrial water pump is used for continuously supplying cooling water, so that the circulating water pump can be started at any time. When the circulating water pump is started normally, the cooling water provided by the industrial water pump can be switched to the cooling water at the outlet of the circulating water pump, and the industrial water pump is stopped. Most heat power station circulating water pumps are designed to be two to three in number, and operators can adjust the running number of the circulating water pumps according to the ambient temperature and the unit load, so that the circulating water pumps in a standby state need to continuously supply cooling water so as to be started at any time. The industrial water pump is operated for a long time to provide cooling water for the circulating water pump, so that the station service electricity of the unit is increased, and the operation and maintenance cost of the unit is increased due to the fact that the industrial water pump is operated for a long time.

The working process of the utility model is as follows:
when the circulating water pump 6 is in a stop standby state, the pressure stabilizing pump 1 is started to fill water into the pressure storage tank 2, the energy storage leather bag 3 is gradually compressed along with the increase of the water filling volume in the pressure storage tank 2, when the internal pressure of the pressure storage tank 2 reaches a certain value, the pressure stabilizing pump 1 is stopped, when the circulating water pump 6 is started, the electromagnetic valve 5 is automatically opened, the stored water in the pressure storage tank 2 immediately enters the circulating water pump cooler 7, at the moment, the outlet pipeline of the circulating water pump 6 is filled with water and gradually pressurized, then the water is sent into the circulating water pump cooler 7 through the circulating water pump self-cooling pipeline 8 through the check valve 9, when the internal pressure of the pressure storage tank 2 is reduced to the outlet pressure of the circulating water pump 6, the electromagnetic valve 5 is closed, and the circulating water pump 6 realizes self-cooling through the circulating water pump self-cooling pipeline 8.
