under water pump

Upper radial bearing which is a water-lubricated tilting-pad journal bearing, is installed in the reactor coolant pump motor, and always runs in high-pressure environments with the temperature of the lubricant under 80 ℃.

上径向轴承结构为水润滑可倾瓦径向轴承，安装在主泵电机内，长期处于高压环境中运行，且运行过程中要求润滑液温度不超过80℃。

Under the condition of main body of boiler wasn't reformed, by upgrading the fire grate and the tail department being heated and fan facilities and water pump, the power upgrading of boiler was realized.

在不动锅炉本体的情况下，仅对炉排、尾部受热面、风机和水泵进行改造，从而实现锅炉的增容。

Water blending under, pump is bound to cause blended water's circling and high water-bearing of produced liquid, which is bad to enhance oil recovery.

泵下掺水易形成掺入水空循环、来出液含水高，不利于提高开采效率。
