(1)结合面漏机油①如果多缸柴油机缸盖螺栓一侧先紧,然后另一侧螺栓后紧,这样一次性紧固螺栓,就会造成机件翘曲而不能压紧垫片,使结合面产生缝隙而漏油。处理方法是:对多螺栓固件紧固时,要用扭力搬手分次对称循环旋紧,保证缸垫上压力分布均匀,才能保持缸盖结合面密封效果。②油底壳的放油螺栓没有旋紧、漏装铜片、螺栓紧力过大、螺栓紧力过小等都会可能造成油底壳结合面漏油。处理方法是:安装螺栓时,垫片不能漏装、错装,同
(1) Joint leakage oil ① If the multi-cylinder diesel engine cylinder head bolts tight side, and then bolt the other side of the tight, so a one-time fastening bolts, it will cause the parts warp and can not be pressed gasket Combination of surface cracks and leakage. Approach is: When the multi-bolt fasteners, torsional force to be used to carry out sub-symmetrical cycle tight, to ensure uniform pressure distribution on the cylinder head, in order to maintain the sealing effect of the cylinder head with the joint surface. ② oil pan oil drain bolt is not tightened, missing pieces of copper, bolt tension is too large, bolt tightness and so may cause oil pan joint surface spills. Approach is: When installing bolts, gaskets can not miss, wrong installation, with
