据资料统计,蒸汽机车汽机密封性能不好,造成的热损失一般占汽机总热量的4～5％,最高的达12～25％。近几年来,路内不少局、段都为降低汽机漏泄而作努力,虽已取得了一定的效果,但还处于不断提高和不断改进的过程中。因此,进一步寻求降低汽机漏泄的方法,对于节约能源,提高蒸汽机车的总效率,提高蒸机车的牵引力,仍然是非常急需的。蒸汽机车汽机密封性能的好坏,由①调整阀到汽室的管系,②汽室阀与汽室套,③汽缸与鞲鞴间的密封性能而定。在这些漏泄处所中,第一项漏泄是可以通过执行工艺、
According to statistics, steam locomotive engine sealing performance is not good, resulting in heat loss generally accounts for 4 ~ 5% of the total steam turbine, the highest of 12 to 25%. In recent years, many offices and sections in the road have made efforts to reduce the leakage of steam turbines. Although some achievements have been made, they are still in the process of continuous improvement and continuous improvement. Therefore, the further search for ways to reduce the leakage of steam turbines is still in urgent need of saving energy, improving the overall efficiency of steam locomotives and increasing the traction of steam locomotives. Steam locomotive engine sealing performance is good or bad, from ① adjust the valve to the steam chamber piping, ② steam chamber valve and steam chamber sets, ③ between the cylinder and 密 的 seal performance may be. Among these leaks, the first leak can be performed by performing processes,
