1小组概况上海铁路局上海电务段转辙机工区QC小组概况见表1。2选择课题2.1除锈脱漆设备故障率高1212P-B悬臂式喷砂机虽然定维护,但因使用期限将至故障频出。主要问题如下:控制电路故障、储砂罐堵塞、密封失效导致漏气。排故效率:2~4人协同,耗时1~4h不等。2.2除锈脱漆设备密封性不良虽然每年对喷砂操作时的粉尘污染的检测都符合国家标准,但漏沙情况依然不容小觑。喷砂设备每使用累计2h就要对地面的铁砂进行清理,极大影响职工工作安全并降
1 Group Overview Shanghai Railway Bureau Shanghai Electricity Depot switch mechanics QC group profile in Table 1.2 Select the subject 2.1 rust paint removal equipment failure rate 1212P-B cantilever sandblasting although scheduled maintenance, To fault frequency. The main problems are as follows: Control circuit failure, storage tank clogging, seal failure resulting in leaks. Discharge efficiency: 2 ~ 4 people synergy, time-consuming 1 ~ 4h range. 2.2 Rust removal paint stripping bad sealing Although the sand blasting operations every year when the dust pollution tests are in line with national standards, but the situation is still not to be overlooked leakage of sand. Sand blasting equipment used every 2h will be on the ground to clean the iron sand, which greatly affect the safety of workers and down
