In addition there shall be a hydraulic accumulator of sufficient capacity.

此外，还装有一个具有足够能量的液压蓄能器。

Chapter two dissertates the component and its configuration of the on-line supervisory control of hydraulic system of walking beam, including the aim, the content and the design principle of this kind of system is also discussed here, and then it introduces the application on network and PLC on-line supervisory control system for this project, including the comparability and affirmance of this system, and also introduces the actual component of this system.

接着论述了基于网络和PLC的监控系统组成在本改造项目中的应用，主要内容有：步进梁液压监控系统方案的比较，方案的确定，实际的在线监控系统的组成以及主要配置等。

Air suction pump noise is caused by one of the main reasons is too high.

1吸空现象是造成液压泵噪声过高的主要原因之一。

The hydraulic parts are made by abrasive hone steel pipes of high accuracy and imported airproof pieces.

液压部件采用高精度珩磨钢管及进口密封件，产品的使用寿命及性能完全能满足客户需要。

Installed new "A" system hydraulic pressure line and clamp in accordance with AMM---.

根 据AMM—更换新的"A"系统液压压力管和安装夹，操作检查正常，无渗漏。

Hydraulic pressure line and clamp in accordance with AMM---. Operationaland leak check good.

据 AMM —更换新的"A"系统液压压力管和安装夹，操作检查正常，无渗

The modeling and the analytic method are very essential.

对此类液压冲击器的建模和分析是十分必要的。

Any aneroid gauge must be calibrated frequently.

任何一种非液压表均必须经常校准。

Howeer, the test gauge also is an aneroid gauge and thus is subject to error itself. Therefore the test gauge must be tested for accuracy by a mercury manometer.

然而这种校对表也是非液压表，因此它本身也会有误差，所以校对表必须用水银测压计校准。

In order to improve the steering characteristics in such a hydraulic power steering apparatus, it was proposed to make the ratio of the relative rotation angle between the two valve elements to the torsion angle of the torsion bar variable see Japanese Patent Application Laid-Open No.

为了改进在这种液压动力转向装置的转向性能，建议将两个阀门元件的相对旋转角度比率依据扭杆变量的扭矩角度而定（参考日本专利申请公开文件1995-117694号）。
