(1)使用环节要注意小油门启动、升温后加速、怠速后熄火。涡轮增压器位于发动机的顶部,其所用的机油来自发动机的油底壳,机油经过机油冷却器和机油滤清器之后,才能到达涡轮增压器,需要一个较长的过程,而涡轮增压器的最高转速可以达到13万转/分钟,即使怠速也可达约8万转/分钟,为了确保增压器全浮动轴承精密件的充分润滑,不发生干磨,一定要小油门启动。发动机启动后,一定 相似文献

Mooring system plays an important role in station keeping of floating offshore structures.Coupled analysis on mooring-buoy interactions has been increasingly studied in recent years.At present,chains and wire ropes are widely used in offshore engineering practice.On the basis of mooring line statics,an explicit formulation of single mooring chain/wire rope stiffness coefficients and mooring stiffness matrix of the mooring system were derived in this article,taking into account the horizontal restoring force,vertical restoring force and their coupling terms.The nonlinearity of mooring stiffness was analyzed,and the influences of various parameters,such as material,displacement,pre-tension and water depth,were investigated.Finally some application cases of the mooring stiffness in hydrodynamic calculation were presented.Data shows that this kind of stiffness can reckon in linear and nonlinear forces of mooring system.Also,the stiffness can be used in hydrodynamic analysis to get the eigenfrequency of slow drift motions. 相似文献
