过去在机器的滑动轴承中,当反映轴承承载能力的参数(PV)超过80公斤/厘米~2·米/秒时,轴承的润滑系统通常都采用强迫循环方式。这样不但耗费材料多,而且制造和安装工时也多。同时还给运行维护和管理带来麻烦。遵照毛主席“节约是社会主义经济的基本原则之一”的教导,根据我厂过去在小型水轮发电机组上推力轴承采用推力头带油的生产经验,自七一年起,在两支点卧式水轮发电机组中,设计和制造了φ200、φ250、φ320三种规格的自循环轴承代替强迫循环轴
In the past, in the sliding bearings of the machine, when the parameter (PV) reflecting the bearing capacity exceeds 80 kg / cm ~ 2 m / s, the lubrication system of the bearing usually adopts forced circulation mode. This will not only cost more material, but also more man-hours of manufacture and installation. At the same time also to the operation and maintenance and management of trouble. According to Chairman Mao “saving is one of the basic principles of the socialist economy,” the teaching, according to my factory in the past on the small hydro turbine thrust bearing with thrust headband oil production experience, since 71, in the two lying Type hydro-generator sets, the design and manufacture of φ200, φ250, φ320 three kinds of self-circulating bearings instead of forced circulation axis
