Tugboat Hujou 101 has been installed with a protecting device for over-speed stopping of the main engine. But in tugging operation when over-speed stopping is suddenly effected, the tugboat will sometimes be endangered by the inertia of the vessel being tugged. To overcome this threat, the writer has made some improvements on the original trigger of the stopping device by turning it into an automtic trigger. When the speed is reduced to starting speed after the main engine has stopped, the trigger...

Tugboat Hujou 101 has been installed with a protecting device for over-speed stopping of the main engine. But in tugging operation when over-speed stopping is suddenly effected, the tugboat will sometimes be endangered by the inertia of the vessel being tugged. To overcome this threat, the writer has made some improvements on the original trigger of the stopping device by turning it into an automtic trigger. When the speed is reduced to starting speed after the main engine has stopped, the trigger will start by itself and so the said danger can be avoided.

沪救101轮上装有主机超速停车保护装置,但在拖带作业中突然超速停车时,由于被拖物继续向前冲,往往威胁到拖船本身.为消除这个缺陷,作者对该轮自动停车装置的原有电路加以改进,构成自动启动电路,当主机停车后其速度降到启动转速时又能自动开动起来,从而消除了上述威胁.

As one of the protecting devices on the equipment of petrochemical and chemical industries, dished rupture-disc has been used Widely. In the application of rupturedisc, it is of great importance to calculate the bursting pressure of the membrane accurately. In literature, most of the previous authors proposed to base the calculation upon the true stresses or experimental data of the membrane material, which is rather troublesome or inaccurate. in this paper, an engineering calculating method is proposed...

As one of the protecting devices on the equipment of petrochemical and chemical industries, dished rupture-disc has been used Widely. In the application of rupturedisc, it is of great importance to calculate the bursting pressure of the membrane accurately. In literature, most of the previous authors proposed to base the calculation upon the true stresses or experimental data of the membrane material, which is rather troublesome or inaccurate. in this paper, an engineering calculating method is proposed to evaluate the bursting pressure with the ultimate tensile strength and strain of the material used, which is more simple and accurate.

预拱型爆破膜是石油化工设备上广泛应用的一种保护装置。精确计算膜片的爆破压力,对爆破膜的使用具有重大意义。过去各国学者所提出的计算方法,是按材料的真应力计算或按材料的实验系数来衡定;用这些方法,计算相当麻烦或欠精确。本文提出一种按照材料的极限拉伸强度及应变以计算爆破压力的工程计算方法。此法较简便且较精确。

The principle of the overvoltage protection device is a Special ZnO resistance element shunted across the secondary terminals of CT. The technical characteristics of the special ZnO element are introduced. The laboratory and field tests of the device are described and the results analyzed. Finally the application and the guiding principle for specification selection of the protecting device are recommended.
