往复式压缩机需要润滑油的位置都有哪些?比如活塞与缸
Reply #22017-07-15
主要润滑方式为油池润滑、强制送油润滑、集中润滑、压力润滑。往复式压缩机注油器提供的压力油注入气缸内,润滑缸套和活塞之间的摩擦副,这两个位置属于强制润滑,润滑油一次性使用,曲轴箱的润滑油通过齿轮升压润滑油曲轴轴承也曲轴轴颈摩擦副,连杆、大小头瓦与曲轴、十字头销两摩擦副,十字头及其润滑道摩擦副,这些属于强制循环润滑方式,电机轴承及盘车器,减速器属于油浴式润滑

活塞环和缸体不一定需要润滑,因为此处润滑有可能会污染介质。设计过程中都讲此处设为少油润滑甚至无油润滑。 润滑油的作用是润滑和冷却。轴承区:此处是最需要润滑的;活塞杆、十字头、连杆、凡是运动摩擦部件都需要。
