The bent pipe makes the flow field of impeller inlet strongly disordered.
与无弯管相比,弯管造成叶轮进口的流场紊乱。
The results show different performance deterioration between different bent pipes, the larger distance between bent pipe outlet and impeller inlet creates more decrease.
结果表明,弯管畸变对离心压气机性能的恶化程度与弯管所在位置有关,距离叶轮进口较远的弯管影响较大。
Set saddles in interval of 1m. Use saddles at two places at 90 bent pipe curve and more than three places at 180 bent pipe curve.
设置固定托架的间隔为1m以下,90度弯曲部位和180度弯曲部位要各使用2个和3个以上的托架。
The ratchet type bent pipe wrench with repositioning rotation function is applied for fast tyre assembling and disassembling operation.
