以滿意構造緊湊的請求，如圖1所示。徑導游葉的正導葉是由螺旋線有些以及螺旋線后邊的分散管有些組成。其用途分別為:內螺旋線有些，用來保證液體在導葉中的自在活動，起搜集液體的效果，而分散有些用來把大有些動能變換為壓力能，起變換動能為壓力能的效果。2徑向正導葉的水力規劃本文所討論的是圖1中的徑向正導葉的水力規劃。2.1規劃原則徑向正導葉混流泵葉輪圖1模型水力構造圖導葉內液體的軸對稱活動。首要應用于農業排灌，市政給排水，電廠供送冷卻循環水，跨流域性調水，海水淡化等大流量中低揚程場合。這些年，也在核電，艦船噴水推進等方面得到應用。導葉多用于節段式多級泵中，它除具有某些構造上的長處外，還能在各種工況下平衡效果于葉輪上的徑向力。

一.概述

High pressure liquid column because of the Russian power outage rapid pouring, impact on the pump outlet valve plate. Treatment method: The pump unreasonable discharge system of the pipeline, pipeline adjacent to the placement of the transformation. The valve of the outlet pipe is closed too fast. Treatment method: Gradually close the valve. According to its tectonic type, the mixed-flow pump can be divided into two kinds of volute shell type and guide vane type. The worm shell mixed-flow pump has two kinds of horizontal and vertical. Now the production and use of a wide range of horizontal, vertical mostly used for large pumps. The structure of the worm shell mixed-flow pump is similar to that of a single-stage single-suction centrifugal pump. But the shape of the impeller is not the same, the outlet edge of the mixed-flow pump blade is skewed, the number of blades is small, the flow channel is wide. The flow of water through the impeller is axial into, oblique out. In addition, the worm shell of the same caliber mixed-flow pump is larger than that of centrifugal pump. Divided into horizontal and vertical two kinds. Usually the mounting angle of the blade can be adjusted with the change of working conditions to maintain operation in the high efficiency zone. The technical requirements for the installation of agricultural pumps are very strict. First, the pump base should be firm.

二.結構和作用

1.HW型泵主要有泵蓋，葉輪，泵體，泵軸，軸套，及軸承體等主要零件組成。 泵蓋分別與泵體和進水管相接。2.泵蓋平面與葉輪平面之間應有適當間隙。間隙過小會產生摩擦，間隙過大，會導致泵體內的壓力水大量回流，是泵的效率降低。實際使用的適宜間隙為0.3-0.7mm，間隙可用增減紙墊厚度來調整。

3.軸套用以保護泵軸，磨損后應及時更換。

1.泵體上端的螺孔，用于加灌引水或連接真空泵抽氣引水。 

2.為擴大泵的適用范圍，滿足用戶不同需求，可切割葉輪外徑或換用不同性能的葉輪。

With three of 4, six of 5, 9. Treatment: adopt the corresponding measures. The oscillation frequency is 0~40% operation speed. Too large bearing voids, loose bearings, oil impurities, oily (viscosity, temperature) bad, because of air or technical liquids to make the shaft foaming, smooth and bad, bearing damage. Treatment: After viewing, adopt the corresponding measures, such as adjusting the bearing voids, eliminating impurities in the oil, replacing the new oil. The oscillation frequency is 60%~100% operation speed. About bearing questions are the same as 2, or the sealing gap is too large, the ring is loose, seal wear. Treatment: View, adjust or replace the seal. The oscillation frequency is twice times the operating speed. No, coupling loose, sealing equipment, shell deformation, bearing damage, support resonance, thrust bearing damage, shaft twists and turns, poor cooperation. Treatment: view, adopt appropriate measures, repair, adjust or replace. The oscillation frequency is n times the operating speed. Pressure pulsation, not deformation of base, Shell.
