管接头包括螺纹管接头(如燃油箱到滤清器的输油管)和锥面接合管接头(如高压油管两端)。造成空心螺纹管接头泄漏的原因有:接头接触平面有拉痕、凹凸不平,配合处突有杂质和污物,密封垫损坏,或空心螺纹管接头和安装壳体上螺丝孔平面配合不严,安装不正或螺母松动也会造成泄漏。排除方法可用砂纸或油石磨平接触面,去除污物杂质,更换损坏的封垫,用什锦锉或砂纸修磨空心螺纹平面及壳体上的螺纹孔,必要时可在专用机床上铣磨。
Fittings include threaded fittings (such as fuel tank to filter delivery tubing) and tapered adapter fittings (such as high pressure tubing ends). The reasons for the leakage of the hollow threaded pipe joints are as follows: the contact surface of the joint has pull marks, unevenness, and the impurities and dirt at the joint place are damaged, or the gasket is damaged, or the hollow screw joint and the screw hole plane on the mounting shell are not coordinated, Improper installation or loose nuts can also cause leaks. Remedy Can be sandpaper or whetstone flat contact surface, remove impurities, replace the damaged seal, with a file or sandpaper grinding hollow thread plane and the threaded hole on the shell, if necessary, milling on a dedicated machine.
