技术领域 technical field
本实用新型涉及一种循环水冷却系统增压结构，属于冷却设备领域。 The utility model relates to a pressurized structure of a circulating water cooling system, which belongs to the field of cooling equipment.
背景技术 Background technique
在一些大型设备生产制造企业通常需要通过循环水来给设备进行冷却，其中供电系统中的主变压器由于产热比较高，需要冷却水的流量比较大，而普通循环水管路中的水压通常在0.3MPa，直接用循环水管路中的水则冷却效果差，设置增压水泵能提高冷却水压至0.6MPa甚至更高，保证主变冷却效果达到额定负荷正常运行。但是传统的增压水泵只是直接在循环水管路上连接出一个分支，增压结构单调，因为气候原因还有主变压器因生产需要功率变化之后，产热量是在变化的，当低产热时只需要普通循环水管路中的水压即能达到相应的冷却效果，此时如果还通过增压水泵散热只会浪费能源，而且增压水泵增加了管路的流速，使冷却水塔需要循环的水量增加，加大了冷却水塔不必要的符合。 In some large-scale equipment manufacturing enterprises, it is usually necessary to cool the equipment through circulating water. The main transformer in the power supply system requires a relatively large flow of cooling water due to its high heat production, and the water pressure in the ordinary circulating water pipeline is usually at 0.3MPa, if the water in the circulating water pipeline is directly used, the cooling effect will be poor. Setting a booster water pump can increase the cooling water pressure to 0.6MPa or even higher, ensuring that the cooling effect of the main transformer can reach the normal operation of the rated load. However, the traditional booster water pump is only directly connected to a branch on the circulating water pipeline, and the booster structure is monotonous. Because of climate reasons and the power of the main transformer changes due to production requirements, the heat production is changing. When the heat production is low, only ordinary The water pressure in the circulating water pipeline can achieve the corresponding cooling effect. At this time, if the booster water pump is used to dissipate heat, it will only waste energy, and the booster water pump increases the flow rate of the pipeline, which increases the amount of water that the cooling tower needs to circulate. Bigger cooling towers don't fit in unnecessarily.
