怎么选购低温冷却液循环泵呢？首先要先确定所使用的温度范围，不同的试验要求需要的温度是不一样的，要求的温度越低价格越贵；其次是要确定冷却液的体积，冷却液的体积越大，装的冷却液越多，所以冷却的量也很大，它的价格也很贵的；后是要看看冷却水泵使用的环境有腐蚀性吗？如果有要用不锈钢外壳，如没有用工程塑料可以了。有的规格低温冷却液循环泵没有可以直接放入液体冷却的浴槽，只有外接的循环冷却的。而有的规格的既有可直接放入冷却液冷却的浴槽，也有外接的循环冷却的。带浴槽功能的体积大点，不带浴槽的体积小点，像电脑主机箱大小，客户在选购时也要注意。总的来说低温冷却液循环泵温度越低价格越贵，体积越大价格也越贵，选用不锈钢外壳价格贵反之价格相对便宜；所以选购低温冷却液循环泵时一定要注意(图\文www.wxjpby.com/)。

How to choose low temperature cooling liquid circulating pump? We must determine the use of the temperature range, different test requirements required temperature is not the same, the temperature is lower the price more expensive; the second is to determine the volume of cooling liquid, cooling fluid volume is large, the cooling liquid loading is more, so the cooling quantity is large, its price is very expensive; the last is to have a look of cooling water pump using environmental corrosion? If must use the stainless steel shell, such as not using engineering plastics can be. Some specifications of low-temperature cooling liquid circulating pump can not directly into the liquid cooling bath, only the external circulation cooling. Some specifications of both can be directly put into the cooling liquid cooling bath, also have external circulation cooling. Take bath function of big, do not take bath size, like the computer host box the size of customers to purchase, also want to notice. Overall low temperature cooling liquid circulating pump temperature is low the price more expensive, the larger the price is more expensive, optional stainless steel housing price is expensive and the price is relatively cheap; so buy low temperature cooling liquid circulating pump must pay attention.
