Closed cooling tower is usually used in the metal melting process with the intermediate frequency furnace cooling equipment.
闭式冷却塔通常是在金属熔炼加工过程中配合中频炉一起使用的冷却装置。
The water pump is an essential component.
其中水泵是必不可少的组成部分。
The water pump of the closed cooling tower includes two parts, one is the spray pump in the spray system and the other is the main circulation pump in the power cycle.
闭式冷却塔的水泵又包括两个部分，一种是喷淋体系里的喷淋泵一种是动力循环中的主循环水泵。
Mainly the use of spray pump to pour cooling water on the surface of the cooler, through evaporation to take away the heat of the coil, to achieve the cooling effect, then the following small series will give you a detailed introduction to the role of the closed cooling tower pump.
主要是利用喷淋泵将冷却水浇注在了冷却器表面，通过蒸发带走盘管的热量，达到冷却的效果，那么下面小编就给大家详细介绍一下闭式冷却塔水泵的作用。
First, the role of closed cooling tower water pump
一、闭式冷却塔水泵的作用
The water pump of the closed cooling tower is divided into two types: spray pump and circulation pump, and its specific role is different.
闭式冷却塔的水泵分为喷淋泵和循环泵两种类型，其具体作用有所区别。
Let's take a look.
下面一起了解一下。
1. Spray pump
1、喷淋泵
The role of the spray pump is mainly to pump the water in the bottom pool of the cooling tower to the top of the cooling tower, and then through the spray pipe by the top of the condenser coil, to play a cooling role.
喷淋泵的作用主要是将冷却塔底部水池里的水抽送到冷却塔顶部，再经由喷淋管道由顶部喷淋在冷凝器盘管上，起到降温的作用。
Cooling the cooling water in the cooling tower tube is to complete the cooling function of the auxiliary cooling tower in high temperature weather, and the water pump flow is required to be large, so that the cooling speed is faster.
让冷却塔盘管内的冷却水降温，是在高温天气辅助冷却塔完成降温的作用，需要的水泵流量要大，这样降温速度更快。
2, circulation pump
2、循环泵
The circulating pump is installed on the auxiliary machine of the power cycle, which plays the role of water transmission from the water tank to the cooling tower coil, and helps the cooling medium (water) circulate between the water tank and the coil.
循环泵是安装在动力循环的辅机上，起到完成从水箱到冷却塔盘管的水源输送作用，帮助冷却介质（水）在水箱、盘管之间往返循环。
The cooling coil is thin, and the pressure of the cooling water into the coil requires a large pressure, so the head is required to be high when selecting the circulating pump, and the flow rate is not too large.
冷却盘管较细，将冷却水加压进盘管需要较大的压力，所以在循环泵选择时要求扬程要高，流量不用太大。
Circulating pump is not necessary equipment, if the cooling medium's own pressure can enter the coil, do not need to be equipped with a pump.
循环泵不是必备装置，如果冷却介质自身压力可以进入盘管则不需要配泵。
