伸缩地

The collapse of bridges due to unseating at intermediate hinges during earthquake emphasizes the need to provide an adequate number of restrainer s to limit the relative displacement between frames in a bridge with inadequate hinge seat width.

在地震中，由于桥联间伸缩缝处过大的变位会造成桥梁破坏，所以需要在支座宽度不足的伸缩缝间设置适当的限位器，以限制伸缩缝间的相对位移。

In the process of developing electrostrictive microfeed driver, it was found that the driving force in the expansion direction of the electrostriction has effect on electrostriction expansion, which increase along with the load.

通过对电致伸缩微位移驱动器的实验研究发现，伸长量方向的力对电致伸缩材料伸长量的影响是随着力的增加而增大，从微观上定性地解释了实验结果。

H.伸缩环转动环伸缩环垫片前轴封 S D / L D / S L M E C H A N I C A L S E A L P U M P S SD/LD/SL SERIES PUMPS The SD/LD/SL series are dependable, self priming pumps. The full motor horsepower is translated into fow via the shaft. These pumps are used for a wide range of applications, from chemical transfer to process solution recirculation to waste treatment. This series is capable of self-priming up ro 20 feet of lift. The mechanical seal is a self-cooling, Tefon bellows which is cooled by the solution being pumped. The construction materials and seals avaiable make this pump extremely versatile. The horizontal design has a working temperature from167℉ to 194℉(75℃ to 90℃), depending on the material of construction, and can handle most chemical solutions. The SD/LD/SL series pumps are designed to run outside the tank or process module. The SD/LD series pumps incorporate a FRPP molded base, legs and pump-to-motor casing. There are no bolts or metallic parts in contact with the solution being pumped.

SD/LD/SL泵是可靠的自吸泵，马达全部的马力经由轴心完全转化为流量，此型泵广泛地使用於从化学药水循环或加工溶液循环到废水处理等各种用途，此型泵可自吸达20英呎，机械轴封是自我冷却的，经由抽送的溶液来冷却，可供应的不同结构材质及轴封使此种泵的用途非常多样化，依其结构材料的不同，其卧式设计的工作温度由75℃到90℃(167℉到194℉)，而且可处理绝大部份的各种溶液，SD/LD/SL是设计用於槽外或加工模组之用，SD/LD加入一个FRPP射出成型的脚座，脚架及泵到马达的外罩，没有螺栓或金属会接触到所抽送的溶液。
