问:柴油机的机座、气缸体和气缸盖为什么会产生变形或裂纹? 答:机座是柴油机的基础,通过它使整台柴油机固定在机舱底座上。机座是以受力为主的机件,除支承柴油机的全部重量外,在运转中还承受来自活塞、连杆、曲轴和飞轮等运动机件的各种作用力,遇到风浪颠簸,还要受到额外的扭转、拉伸和弯曲变形作用力。如果机座刚性不足,或因其他偶然原因而变形,就可能引起运动机件失去正确的中心线,柴油机将不可能继续正常运转。所以应特别加强对机座变形的注意和检查。 柴油机的机座变形或产生裂纹,通常由下列原因造成:
Q: Why diesel engine base, cylinder block and cylinder head deformation or cracks? A: The base is a diesel engine, through which the entire diesel engine is fixed on the base of the cabin. Base is based on force-based mechanical parts, in addition to supporting the full weight of the diesel engine, in operation also from the piston, connecting rod, crankshaft and flywheel and other moving parts of the various forces encountered rough bumps, but also To be subjected to additional twisting, stretching and bending deformation force. If the frame stiffness is insufficient, or because of other accidental deformation, it may cause the movement of mechanical parts lose the correct center line, the diesel engine will not be able to continue normal operation. Therefore, special attention should be paid to the deformation and inspection of the base. Diesel engine base deformation or cracks, usually caused by the following reasons:
