题目

As the branch point,non-return valve and pump are usually located close to each other.
As the branch point,non-return valve and pump are usually located close to each other,the pump could still be subject to overheating through the heat conduction via the pipe in some cases.Therefore,it is also conceivable to install the stagnation cooler parallel to the return or together with the expansion tank in the feed,though then possibly with other disadvantages.
很多地方不懂,什么叫As the branch point,install the stagnation cooler parallel to the return,together with the expansion tank in the feed.

答案

由于分支点的存在,单向阀和泵通常装配在一起,某些情况下,泵可能还会遭受通过管道传导的过热情形.因此,在回返管道(return)平行方向或者与膨胀箱一起安装停滞冷却器作为反馈是可以理解的,尽管也许会造成其他的缺陷.
