During the normal operation of the circulating cooling pump of the oil station of the induced draft fan, the blower and the primary fan (hereinafter referred to as three fans), the starting frequency is mainly influenced by the environmental temperature and the load of the unit. Under the working condition of high load in winter, the starting frequency of the circulating cooling pump reaches 4-8 times/hour, the starting and stopping of the high frequency easily causes motor burning loss, further causes the fault of a cooling system of a fan oil station, and shortens the service life of the cooling system of the fan oil station.
Through the analysis, the circulating cooling pump starts high-frequency and stops the main reason and lie in: the starting frequency of the circulating cooling pump of the fan oil station is greatly influenced by unit load and environment temperature, the unit load mainly influences the return oil temperature of fan lubricating oil, and when the unit load is higher, the return oil temperature of the lubricating oil is higher, and the temperature in an oil tank rises quickly; ambient temperature mainly influences coolant liquid temperature, and during winter, coolant liquid temperature is lower, and when the circulative cooling pump started, because coolant liquid flow can not automatically regulated, oil temperature cools off fast in the oil tank to lead to fan oil station circulative cooling pump to open frequently and stop.
From the reason analysis, it can be seen that controlling the coolant flow is an effective method for changing the number of start-stop times of the cooling oil pump. Therefore, the general idea of the solution of the present invention is to add a temperature control assembly 40.
To this end, the present invention provides an oil station cooling system, as shown in fig. 1, comprising: a circulation line 10, a circulation cooling oil pump 30, and a cooling mechanism. Wherein the circulation line 10 can form a liquid circulation loop with the oil tank 20. Specifically, the circulation pipeline 10 includes a liquid inlet end and a liquid outlet end, and the liquid inlet end and the liquid outlet end are respectively communicated with the oil tank 20 to form a liquid circulation loop. The circulation cooling oil pump 30 is installed on the circulation line 10. The cooling mechanism comprises a temperature control assembly 40 and an oil cooler 50 installed on the circulating pipeline 10; the oil cooler 50 comprises a cooling pipeline which comprises a liquid inlet pipe 51 and a liquid outlet pipe 52; the temperature control assembly 40 is arranged on the cooling pipeline and used for controlling the flow of the cooling liquid in the cooling pipeline.

The temperature/water amount adjustment valve 41 controls the flow rate of the coolant based on the temperature signal. In practical use, a region value can be set, when the temperature is higher than the set threshold value, the flow rate of the cooling liquid is increased, and when the temperature is lower than the set threshold value, the flow rate of the cooling liquid is reduced, so that the temperature of the oil in the oil tank 20 is kept within the region value, and the start-stop frequency of the circulating cooling pump is reduced or the circulating cooling pump is kept running for a long time.
