磨:即磨合。无论是新的还是大修后的柴油机,都必须按规范磨合后方可投入正常作业。 净:即油净、水净、气净、机体净。若柴油不净,会使轴颈和轴瓦间隙变大、油压降低,甚至造成抱轴烧瓦等严重事故。若空气中含有大量尘土,将会加速缸套、活塞和活塞环的磨损。若冷却水不净,会影响发动机散热,使机件磨损严重。若机车外表不净,会使机体表面受到腐蚀。 足:即油足、水足、空气足。若柴油和空气供应不及时,就会出现起动困难,冒黑烟,功率下降等现象。若机油供不应求,会使机件严重磨损、甚至烧瓦。若冷却水不足,会使机
Mill: That run-in. Whether it is a new or overhauled diesel engine, it must be put into operation according to the specifications before it can be put into operation. Net: that the net oil, water net, air net, the body net. If the diesel is not clean, the gap between the journal and the bearing bush will be enlarged, the hydraulic pressure will be reduced, and even serious accidents such as the axle shingling may occur. If the air contains a lot of dust, will accelerate the cylinder liner, piston and piston ring wear. If the cooling water is not clean, it will affect the engine heat, causing serious wear and tear parts. If the locomotive appearance is not clean, will make the body surface corroded. Foot: that is enough oil, water enough, enough air. If the diesel and air supply is not timely, there will be difficulties starting, black smoke, power and other phenomena. If the oil in short supply, will cause serious wear and tear of the parts, or even burning tiles. If the lack of cooling water, will make machine
