In order to meet the need of economic development for large-specification roll of steel plates, technical improvements have been carried out in the hot-rolling mill. The six sets of high pressure water pump, which cannot provide high enough speed of water supply for rolling, is replaced using three sets of high pressure centrifugal pump. The working mode of three sets of high pressure centrifugal pumps is that two pumps work and another one is spare. After the project has been carried out other problems emerge, for example, the electromotor becoming very heat and the pump being frequently attainted.

为了适应经济发展对轧制大规格的热轧板卷的需要，热轧板厂对轧线进行了技改，将6台不能满足快节奏高速轧制供水的高压柱塞泵更换为3台高压离心泵，三台高压水泵采取两用一备工作状态，投运以来，又出现电机严重发热，泵频繁损坏的问题。

而高压滤波电感可以等效到低压星点处，使滤波电感绝缘等级低，通过提供电感续流通道给星点电感预充电，补偿了高压直流开关合分闸时负载电压跌落和过冲，降低电源动态内阻，加速了脉冲边沿动态响应过程，特别适用于需要快速响应脉冲高压电源的微波功率放大元件

To avoid this, high pressure foam generating procedure must be applied, which means high pressure purified water or deoxygenated water must be fed into the bottle with small flow under high pressure, thus raising CO2 in the beer to the bottle neck as foam to remove gas from the bottle neck and dropping oxygen content in the bottle neck.

可通过增加高压激泡工序，即将高压纯净水或脱氧水以微小的水流高压注入瓶中，使啤酒中的CO2以泡沫形式上升至瓶口，排走瓶颈的气体，达到减少瓶颈气体含氧量的目的。

And the westward ISO is usually the low-frequency low and high pressure systems from the Bay of Alaska in northeastern Pacific and the Okhotsk in the northwestern Pacific of mid high latitudes, and the ISO evolving in subtropical easterlies.

进一步分析发现，经向风ISO的纬向传播对应着大气经向型环流系统的移动，向西传影响东亚夏季风区降水的ISO有来自低纬中东太平洋东风流中的低频气旋（如副热带东风带中ISO的演变）；也有来自中高纬度阿拉斯加湾及鄂霍次克海一带低频低压和高压(如阻塞高压和东北太平洋高压)的向南向西频散。

In the design of the supercritical high pressure feed water heater,choose the two kinds of materials of WB36 and 15CrMo at the same time,the high pressure feed water heater must carry on the whole heat treatment,so the anneal temperature of WB36 must be raised above 600 ℃ to satisfy the request of the whole function of the high pressure feed water heater.
