It is assumed that it is adiabatic compression during start-up process before the atmophere pressure in flow passage rise to relief pressure, the thermodynamic equation, momentum equation and rigid water hammer theroy have been applied for the analysis and calculation the variation law of air during this transient process.

假设流道内气体未达虹吸驼峰顶处真空破坏阀排气压力前的起动过渡过程处于绝热压缩状态，运用能量方程结合动量方程和刚性水击理论，计算分析出了流道中的气体压力在起动过渡过程中的变化规律。

During the compression, room between the compressor's rotor and cylinder reduces. Oil content in the compressed air will be lower than 2PPM after the compressed oil-air mixture goes through mechanical separation and filtering separation. Purified compressed air will cool down in aftercooler. Condensated water after the cool-down is drained out solenoid valve.

在压缩过程中，压缩机转子的滑片与气缸之间容积不断减少，压缩后的油气混合气3/4机械分离和过滤分离，使压缩空气中含油量低于2PPM.3/4净化后的压缩空气进入后冷却器中进行冷却，冷却后所形成的凝结水3/4由一排水电磁阀而排出。

After operating 16 hours each time, open drain valve of air bottle and exhausted water.

3.5 每运转16小时后，应将空气瓶的放残阀打开，将水放尽。

The application of the alloy that can effectively reduce the release of hydrogen, the special technique in manufacturing grid, and the appropriate match of active materials of both negative plates and positive plates, all these enable spiral valve-regulated sealed lead-acid battery , greatly restrain the release of hydrogen from negative plates, at the same time the generated oxygen, due to overcharge of positive plates, arrive at negative plates through the diaphragm and compose with lead in the negative, thus enable the recombination of gas inside of the battery and prevent the case of water loss so that water addition is free.

外型尺寸参考具体型号产品认证 ISO9001，CE，UL卷绕式阀控密封铅酸蓄电池通过采用具有极高析氢过电位的合金通过特殊工艺制造板栅，同时对正负极活性物质量的合理匹配等工艺措施，使得负极上发生的析氢过程得以最大限度地受到抑制，同时正极因过充电所产生的氧气通过隔膜到达负极，并与负极上的铅发生反应，生成水，这样便使得电池内部气体的再复合，防止失水，实现免维护。

Closing of watertight doors, fire doors, valves, scuppers, sidescuttles, skylights, portholes and other similar openings

船上水密门、防火门、阀、泄水孔、舷窗、天窗、装货舷门以及其他类似开口的关闭

When the pump to work, you can cut off the water through the valve and pump impeller ring round access, and release the water within the liquid ring round.

当泵正常工作后，可通过阀截断水环轮和水泵叶轮的通道，并且放掉水环轮内的液体。

The paper describes the reason why the 1000MW ultra supercritical steam turbine with HP single bypass valve using HP casing start-up was not applied with HP exhaust non-return valve and introduces the methods to prevent over-speed for load rejection,HP casing overtemperature and water admission.

论述了采用高压缸启动方式的带高压一级旁路的1000MW超超临界汽轮机不设高排逆止门的依据及其防止汽轮机甩负荷超速、高缸超温与进水的方法：一是在高压导汽管上加装通风阀，二是在冷再管上加装通往凝汽器的排汽管，三是在冷再管的低位加装能显示水位、自动报警及自动疏水的疏水罐。

The 2300 Direct Operated Reducing Valve is designed for deadend water service where the flow is intermittent and changes rapidly, as on domestic water systems.

系列2300直接操作减压阀适用于室内水系统流量有间歇性变化和变化迅速的终端水应用场合。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
