我厂使用的20m~3空压机由于冷却水泵出现故障,停机后没有及时放水(当时是冬季,室内温度为-10℃)将一级缸缸体冷却壁冻裂掉,二级缸冻裂一条与缸体等长的裂缝。由于生产急需使用,我们采取了非拆卸补焊粘接方法对缸体进行修复,取得了良好的效果。实践证明此种修复方法省时、省力、节省费用,具有一定实用价值。 I use 20m ~ 3 air compressor plant due to cooling pump failure, no timely discharge after shutdown (when it is winter, the indoor temperature of -10 ℃) will be a first-cylinder cooling stave off the cooling wall, two-stage cylinder cracking A long gap with the cylinder. Due to the urgent need of production, we adopted a non-demolished repairing welding method to repair the cylinder and achieved good results. Practice has proved that this repair method saves time, effort, cost savings, has a certain practical value.
