Impeller fixed on the bearing whether there is loosening, if there is cracks and loosening phenomenon to timely maintenance, if the stainless steel horizontal mixed pump impeller above the soil also need to clean up. Stainless steel horizontal mixed flow pump and pipe interface must be well sealed, because if there is debris into the words will be damage to the inside of the stainless steel horizontal mixed flow pump. For stainless steel horizontal mixed-flow pump bearings are also the focus of inspection, after use to check whether the bearing wear, if the stainless steel horizontal mixed pump for a long time if the small ball in the bearing will be broken, so when the stainless steel horizontal mixed pump after use in the bearing is best coated with a layer of lubricating oil better protection pump bearings. The perbance of stainless steel horizontal mixed-flow pump depends not only on the beter index, but is often the result of people using it properly. Summer is here, and the flood season is not far off. In order to complete the drainage in time during the flood season, it is necessary to ensure that the mixed flow pump, axial flow pump and other drainage equipment can operate normally during the drainage period. On this point.

高比轉(zhuǎn)速混流泵的設(shè)計(jì)方法
軸面流動(dòng)計(jì)算
采用流線迭代法求解軸面流動(dòng).流線迭代法基于沿任意準(zhǔn)正交線的軸面速度梯度方程和流體運(yùn)動(dòng)的連續(xù)方程,根據(jù)各子流道流量相等的原則,迭代求解沿準(zhǔn)正交線的軸面速度梯度方程即可得到軸面流網(wǎng).通過流線迭代法,在確定軸面流道輪廓之后,可以通過所需時(shí)間很短的迭代計(jì)算過程得到的軸面流網(wǎng).圖1是流網(wǎng)所對(duì)應(yīng)的軸面速度沿軸面流線的分布圖.
