At the same time, it had good friction-reducing performance with a smooth transition from fluid film lubrication at low temperature to solid film lubrication at elevated temperature, which could fit the need of lubrication in a wide temperature range. 实验结果表明,纳米硫代钼酸镍颗粒作为润滑油添加剂具有良好的分散稳定性和抗磨性,可以实现从室温的流体润滑形式平稳过渡到高温时的固体润滑形式,满足宽温度范围减摩的需要。
The spiral groove mechanical seal in whose one of two faces is grooved some hollow spiral grooves makes the two faces non-contact by a fluid film resulted from the hydrodynamic effect of the spiral grooves, which greatly improve the lubrication condition and extend the seal life. 端面开有螺旋浅槽的机械密封,利用流体动压效应,使两密封端面被&流体膜分开,形成了非接触,极大地改善了密封端面的润滑状况,延长了密封的寿命。
The results show that equivalent viscosity of fluid induced by the effect of electric double layer apparently increases with decrease of thickness of the film while lubrication film is thin enough. 结果表明:在薄膜厚度较薄的情况下,双电层效应使得流体的等效粘度随膜厚减小而迅速增加;
Meanwhile, the fluid film can provide lubrication and cooling for the friction pair, which guarantee that the seal rings can work for long without abrasion. A theoretical analysis model is developed for the flow field in the seal gap. 同时,流体膜可以为摩擦副提供润滑和冷却,保证密封环可以长时间工作而不磨损,具有良好的稳定性。
