选煤振动筛有4个或6个大滚动轴承需要同时注入润滑脂润滑,为同时向多个润滑点提供润滑,研制了主要由自制的多路润滑脂泵(即有多个出脂口的润滑脂泵)和传压活塞式脂压表等组成的集中润滑系统,将润滑脂直接注入到多个润滑点,可省去润滑脂分配器。集中润滑系统有良好的特性,每个润滑点与润滑脂泵相应的柱塞相连,各自形成独立管路系统,在任何情况下各自供脂,不因某一点堵塞或阻力增大而改变其它润滑点的供脂量。分析了自制多路润滑脂泵和传压活塞式脂压表的动作原理和研制过程。
Coal shaker with 4 or 6 large rolling bearings need to inject grease lubrication at the same time to provide lubrication to multiple lubrication points, developed mainly by the homemade multi-way grease pump (that is, with a number of grease outlet lubrication Grease pump) and pressure transmission piston pressure gauge and other components of the centralized lubrication system, the grease directly into multiple lubrication points, eliminating the need for grease dispensers. The centralized lubrication system has good features. Each lubrication point is connected to the corresponding plunger of the grease pump to form a separate pipe system, which in each case feeds its own lip and does not change due to a certain point of blockage or increased resistance to other lubrication Point of fat supply. The operation principle and development process of self-made multi-way grease pump and pressure transmission piston grease gauge were analyzed.
