氟塑料金属又称金属氟塑料,是一种新型的耐磨轴承材料。在无产阶级文化大革命的推动下,有关科研部门坚持独立自主、自力更生的方针,在较短时间内试制成功。这种材料是用氢气保护炉将直径0.1毫米左右的铜球烧结在钢底板上,成为1～2毫米厚的海绵状结构,然后真空浸渍聚四氟乙烯和铅的混合物而制得。它的耐温范围-200～+280℃,承载力高,具有优良的摩擦—磨损特性。我们将这种材料用来制作增频潜油电机的止推轴承,取得了良好的效果。现将有关情况简单作一介绍。 1.增频潜油电机止推轴承的工作参数 Fluorine plastic metal, also known as metal fluorine plastic, is a new type of wear-resistant bearing materials. Under the impetus of the proletarian cultural revolution, relevant scientific research departments adhered to the principle of independence and self-reliance and successfully piloted the trial in a relatively short period of time. This material is sintered with hydrogen gas to about 0.1 mm in diameter copper ball sintered on the steel floor to become 1 to 2 mm thick sponge-like structure, and then vacuum impregnated mixture of PTFE and lead in the system. Its temperature range -200 ~ +280 ℃, high bearing capacity, with excellent friction - wear characteristics. We use this kind of material to make the thrust bearing of the frequency-increasing submersible motor, and achieved good results. Now the situation is simple to make an introduction. 1.
