To overcometwo basic drowbacks of the old structure, this artical puts forwarda new structure which is made of piston, and introduces it's first practical running test.

    本文通过理论分析给出了传统结构的泵轴填料密封压紧力分布普遍式,指出了必然存在的两大基本缺点:①压紧力分布极不合理,引起严重过压;②填料磨耗后不能自动补偿,引起维护麻烦、泄漏量大。为此,提出了克服两大基本缺点的新结构──活塞压盖式填料自紧轴封,并介绍了新结构的初次应用试验情况。

    The article points out the harm done to equipment and production owing to the motor-pump shafts running out of axial center, revealing that as the construction and inspecting criteria vary for installation of motors and pumps, the present pipeline construction companies have to have some work redone wastefully. To meet "The State Standard", a simple and practical method is particularly introduced to correct and adjust the motor-pump shafts, which is proved OK through data computation. It is...

    The article points out the harm done to equipment and production owing to the motor-pump shafts running out of axial center, revealing that as the construction and inspecting criteria vary for installation of motors and pumps, the present pipeline construction companies have to have some work redone wastefully. To meet "The State Standard", a simple and practical method is particularly introduced to correct and adjust the motor-pump shafts, which is proved OK through data computation. It is suggested to popularize it in order to highten the engineering installation quality.
