德國VOITH(福伊特)液力偶合器的工作原理以液體為工作介質(zhì)的一種非剛性聯(lián)軸器，又稱液力聯(lián)軸器。液力偶合器的泵輪和渦輪組成一個(gè)可使液體循環(huán)流動(dòng)的密閉工作腔，泵輪裝在輸入軸上，渦輪裝在輸出軸上。動(dòng)力機(jī)(內(nèi)燃機(jī)、電動(dòng)機(jī)等)帶動(dòng)輸入軸旋轉(zhuǎn)時(shí)，液體被離心式泵輪甩出。這種高速液體進(jìn)入渦輪后即推動(dòng)渦輪旋轉(zhuǎn)，將從泵輪獲得的能量傳遞給輸出軸。最后液體返回泵輪，形成周而復(fù)始的流動(dòng)。液力偶合器靠液體與泵輪、渦輪的葉片相互作用產(chǎn)生動(dòng)量矩的變化來傳遞扭矩。它的輸出扭矩等于輸入扭矩減去摩擦力矩，所以它的輸出扭矩恒小于輸入扭矩。液力偶合器輸入軸與輸出軸間靠液體聯(lián)系，工作構(gòu)件間不存在剛性聯(lián)接。液力偶合器的特點(diǎn)是：能消除沖擊和振動(dòng)；輸出轉(zhuǎn)速低于輸入轉(zhuǎn)速，兩軸的轉(zhuǎn)速差隨載荷的增大而增加；過載保護(hù)性能和起動(dòng)性能好，載荷過大而停轉(zhuǎn)時(shí)輸入軸仍可轉(zhuǎn)動(dòng)，不致造成動(dòng)力機(jī)的損壞；當(dāng)載荷減小時(shí)，輸出軸轉(zhuǎn)速增加直到接近于輸入軸的轉(zhuǎn)速，使傳遞扭矩趨于零。液力耦合器的傳動(dòng)效率等于輸出軸轉(zhuǎn)速與輸入軸轉(zhuǎn)速之比。一般液力偶合器正常工況的轉(zhuǎn)速比在0.95以上時(shí)可獲得較高的效率。液力偶合器的特性因工作腔與泵輪、渦輪的形狀不同而有差異。它一般靠殼體自然散熱，不需要外部冷卻的供油系統(tǒng)。如將液力偶合器的油放空，偶合器就處于脫開狀態(tài)，能起離合器的作用。

The 1,400-kilometer Dampier-to-Bunbury Pipeline (DBN) is one of Western Australia?s key energy supply assets. The 26-inch DBN pipeline is owned by Dampier-to-Bunbury Natural Gas Pipeline (DBNGP) of Perth and delivers gas from the Carnarvon Basin in the North West Shelf to industrial, commercial and residential customers in the city of Perth and the surrounding region.

Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). In some cases, pipe is shipped to the pipeline construction site as "double joints," where two pieces of pipe are pre-welded together to save time. Most of the pipe used for oil and gas pipelines is seamless or longitudinally welded, although spirally welded pipe is common for larger diameters.
