| 摘 要： | 以流体动力学为基础,基于混凝土泵送设备两个输送缸交替送料的特点,提出一种新型的双向润滑系统,对该系统进行数学建模及分析,通过求解得到砼活塞唇口处润滑点的油膜厚度曲线,并在实际中得到验证.双向润滑系统不仅可以改善泵送设备结构运动副的润滑效果,延长泵送系统的使用寿命,而且能够减少润滑剂使用量约33%,降低成本,减少对环境的...

| Abstract: | On the basis of fluid dynamics, a new type of dual directions lubrication system is suggested based on the feature that the two cylinders of concreter pumping equipment pump alternately. Mathematic modeling and analysis are carried out for the system. The oil film thickness curve at the opening end of the piston is obtained and verified in practice. The dual direction lubrication system not only improves lubricating effect of pumping equipment structural kinematic pairs, prolongs its service life but also s... |
