过去,我厂水泵大都采用各种牌号不一的润滑脂进行润滑,轴承使用寿命短。主要原因是润滑不良,造成相对运动表面的烧损,轴承损坏。改用本溪润滑材料厂生产的三号二硫化钼锂基脂后,轴承的使用寿命延长了约三分之一,而且,近三年来再未出现由于润滑不良而造成轴承烧坏的事故。从164天(3150小时)的运行记录数据(表1)表明,使用二硫化钼锂基脂后,电流值明显下降,出水压力经一千多小时运行后有所提高,这就说明水泵的实际使用效率有所提高。
In the past, most of our pumps used a variety of brands of grease for lubrication, bearing life is short. The main reason is poor lubrication, resulting in the relative movement of the surface of the burning, bearing damage. The use of Benxi Lubricating Material Factory production of three lithium molybdosilicate lithium grease, the bearing life of about one-third, and, in the past three years and no longer appear as a result of poor lubrication and bearing accidental burn out. Operating data from 164 days (3150 hours) (Table 1) show that after using lithium molybdosulfide grease, the current value dropped significantly, and the outlet pressure increased after more than 1000 hours running, which shows the actual situation of the pump Use efficiency has improved.
