  动密封部分的检修 离心泵机泵的动密封是指叶轮口环部位的密封, 一般半径方向应控制在0. 20～0. 45 mm。若间隙太小,组装后盘车困难; 间隙太大, 容易造成泵的振动。轴套和衬环间隙半径方向一般为0. 2～0. 6 mm。 　静密封部分的检修 化工泵静密封部分包括泵体剖分结合面、轴承压盖与轴承箱体的结合面、润滑油系统的接头、进出口管的法兰等, 如检修不能保证无泄漏, 也同样使泵不能运行。上述部位的密封, 只要根据介质选准适用的胶粘剂和垫片, 即能保证无泄漏。现一般使用的剖分结合面胶粘剂为南大703、南大704。

Chemical pump-action sealing and static sealing parts of the maintenance Dynamic seal part of the overhaul Centrifugal pump impeller dynamic sealing means sealing the mouth parts of the ring, generally radial direction should be controlled at 0. 20 ~ 0. 45 mm. If the gap is too small, after the disk drive assembly difficulties; the gap is too large, likely to cause vibration of the pump. Sleeve lining ring gap and the radius direction is generally 0. 2 ~ 0. 6 mm. Static seal part of the overhaul Static seal chemical pump parts including pump with subdivision surfaces, bearings and bearing box gland combination of surface, lubricating oil system, joints, flanges and other import and export of pipe, such as the maintenance can not guarantee no leakage, the pump can also run. The parts of the seal, as long as the application of adhesives based on selecting the right media and gaskets that can guarantee no leaks. The subdivision is generally used with the adhesive surface 703 for the South, South 704.
