水泵

Under normal conditions,one cooling water pump and one heat exchanger of closed-circuit cooling water is satisfiable for the requirements of the overall system.

正常情况下一台冷却水泵和一台闭式循环冷却水热交换器可满足整个系统所需的冷却水量，夏季需投运2台冷却水换热器满足机组运行要求。

In 1698 English engineer Thomas Savery developed a water pump that used steam from a boiler for its power.

萨维瑞发明了用锅炉中的蒸汽作为动力的水泵。

And at this basement, analyzes the matching design between screw propeller and diesel engine, according design theory of screw propeller chart.

目前常用的螺旋桨图谱匹配设计涉及大量图、表及繁多复杂的计算公式，并且各图表有特定的适用范围，不利于设计应用和推广；船舶冷却系统中冷却水流量、水泵排量等主要依据主机标定点设计，而船舶在实际航行过程中主机主要运行在部分负荷状态，这样就造成了冷却能力过剩，冷却水温度过低，影响主机性能的发挥。

The SEADOG pump system, which was tested in the Gulf of Mexico , works by capturing ocean-wave energy from swells or waves to pump large volumes of seawater to shore-based storage or sea-based platform systems while consuming no fuel.

SEADOG泵系统在墨西哥湾经过测定。通过从巨浪和水浪中获取海洋能，它能够在不消耗燃料的同时将大量的海水泵送至岸上的水库或者是海上的平台系统。

The SEADOG doesn't involve any electrical components that can be damaged by sea water, and, because the device pumps water to a reservoir, it can store salt water or desalinated fresh water in the form of potential energy to generate power on demand, even if the current wave regime during a particular period is too low to generate power.

SEADOG pump不会陷入任何电力组成部分的困扰——这些部分通常容易被海水损坏。另外，因为，这套装置是把水泵送至蓄水池，所以在需要甚或特殊时期的海浪过低而不能产生电力时，它可以将盐水或者是淡化海水转化作为势能"储备"起来。

First, the water pump mechanical seal ring on the surface of metal corrosion.

第一，水泵的机械密封上金属环表面均匀腐蚀。

Inspection of the pump shaft seal ring, such as wear parts should be replaced.

检查水泵轴的油封环，如磨损严重应更换新件。

In addition, before, we must check the pump body of water storage, or self-absorption not only affects performance, and easy to seal parts burned.

另外，在启动前，一定要检查水泵体内的存水量，否则，不仅影响自吸性能，而且易烧毁轴封部件。

As an added feature, for semipermanent or overnight installations, the valve will also supply water automatically as needed to the tank thereby eliminating manual filling and pumping, and saving wear and tear on the water pump or compressor.

作为一个附加的性能，适用于非永久性或过夜安装，这种阀门还能够根据需要自动将水供应到容器内，因此避免人工注水和接管，减少水泵或压缩机的磨损和划伤。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
