排灌机械中的轴承结构形式和其寿命、泵轴运转振动性有极其重要的关系。目前许多排灌机械中轴立式放置的水泵采用组装后成纯圆形的椽胶轴承,酚醛塑料导轴承,就此谈谈自己的看法与大家磋商。轴立式放置,纯圆形的轴承关键不能形成动压液膜,影响泵轴的旋转精度,造成振动,使轴承与轴的寿命不能更长。其原因分析如下:以江都排灌站三站3号、8号机组改造后的 P23酚醛塑料异轴承为例(其他各站各 Drainage and irrigation machinery in the form of bearing and its life, the vibration of the pump shaft has an extremely important relationship. At present, many vertical shaft pumps for drainage and irrigation machinery are assembled into pure circular rafters, phenolic plastic bearings, so as to talk about their own views and discuss with you. Vertical shaft placed, the key is not a pure circular dynamic pressure fluid film, affecting the shaft rotation accuracy, resulting in vibration, so that the bearing and shaft life can not be longer. The reasons for the analysis are as follows: Take Jiangdu Irrigation and Drainage Station three stations on the 3rd, No. 8 P27 modified phenolic plastic bearings as an example (the other stations
