冬季,有些柴油机因忘记放冷却水,气缸体冻裂了(内部没有裂),冷却水向外漏。对此,我们采取以下修复方法:首先在裂纹的两端用直径2毫米的细钻头钻孔,目的是防止裂纹在发动机工作时继续延伸。接着在裂纹的四周,钻直径为6.8毫米的孔,然后再套M8×1.25的丝扣,螺孔之间的距离为25毫米。要注意的是:对应边螺孔的位置应错开(如图中1和2的位置应相错)。再用螺钉将钻孔后的石棉板(1毫米厚)与钢板(1～1.5毫米厚)拧在气缸体上(石棉板的两面要抹上铅油)。上紧螺钉时,一定要按对
In winter, some diesel engines forget to put the cooling water, the cylinder body cracked (no internal cracks), the cooling water leaked out. In this regard, we take the following repair method: First, the two ends of the crack with a small diameter of 2 mm drill bit, the purpose is to prevent cracks in the engine to continue to extend work. Next, around the crack, drill a hole with a diameter of 6.8 mm and then set a M8 × 1.25 thread. The distance between the holes is 25 mm. It should be noted that: the corresponding side screw position should be staggered (as shown in Figure 1 and 2 should be wrong position). Screw the asbestos board (1 mm thick) and the steel plate (1 to 1.5 mm thick) on the cylinder block with screw (use lead oil on both sides of the asbestos board). When tightening the screws, be sure to press right
