波纹的

For the high temperature above 300 ℃ medium, not only泵头need some cooling, the suspension should also be room bearing a cooling system, pump structure of the general form of support for the center, the mechanical seal the best use of metal bellows-type, but the high price ( Price is the general closure of the 10-fold).

对于300℃以上的高温介质，不仅泵头部分需要冷却，悬架轴承室也应设有冷却系统，泵结构一般为中心支承形式，机械密封最好采用金属波纹管型，但价格高（价格是普通机封的10多倍）。3。

The section of traditional portal rigid frame are constant cross-section and wedge shape variable cross-section,this paper brings up a component cross-section—ripple web plate variable cross-section.

传统的门式刚架的构件截面为等截面和楔形变截面，本论文提出了一种构件截面形式——波纹腹板变截面。

Because the shredding process can create dust, it's not recommended for consumer products, but it's an ecologically sound way of handling corrugated for one more use while saving on the costs of dunnage supplies.

由于粉碎过程可能产生粉尘，所以不推荐给消费产品使用，但它是处理多用波纹垫料用品的节省费用且无害的方式。

The cups also feature an extra-long bellows that adds forgiveness at the moment where cup meets bag.

该杯还具有一个额外的波纹管，增加了宽恕的时候，世界杯符合袋。

After the modification, the acetaldehyde consumption and energy consumption were reduced by about 10% respectively, and install time of the towers was only about 1/5 of the float valve towers with cutting 60% of the cost.

采用JKB-125Y型板波纹填料塔代替浮阀塔，对乙醛分馏塔和酒精回收塔进行改造，乙醛单耗及能耗可降低10％，塔设备的投资可节约60％，塔设备安装时间可缩短至原来的1/5。

Therefore, in order to guarantee the stability of production, but also to reduce the actual running costs, heat-conducting oil bellows system should be chosen cut-off valve can not be selected filler valve seal or valve.

因此，为了保证生产的稳定，也为了降低实际运行成本，导热油系统应该选用波纹管截止阀，不能选用填料密封的截止阀或闸阀。

In this paper, the manufacturing technology of isolator with multi-layer steel stripe...
