“洪大爷”:旅客列车集便器改造大王(朱菊芬 胡婷芬摄)
央广网重庆8月24日消息(记者刘湛 通讯员朱菊芬 胡婷芬)“洪大爷”真名洪斌,四十多岁,因业务上的实力而得“洪大爷”之称。
洪斌是2006年开始到真空集便装置检修岗位。刚到这个岗位的他对真空集便器装置是完全知之甚,但这并没有难倒当过车电员、发电车司机的他。他从车上配电柜中的集便端电器电路图开始学起,对集便配件检修技术进行了解掌握,很快成为集便检修专家。2014年5月,洪斌从乘务车间集便专修组调到吉通加工厂,担任配件班工长,带领职工进行客车真空集集便装置技术攻关。
刚到加工厂时,作为师傅的他,开始手把手教新来的职工。为了让职工尽快掌握维修要领,他将集便装置各配件进行梳理,将这些配件的名称、型号、工作原理、作用、故障处理方法一一对应给新工讲,三个月后,这些毫无基础的新工都能独立完成真空集便装置配件的的检修与试验。
除了干好工作当好师傅,洪斌还是一个改造专家。由于集便器的配件规格型号较多,大小尺寸精确度要求高,允许误差仅0.1mm,大了或小了都不好使用。还有一些配件,是整体焊接的,只能一次性使用,坏了,就得整体更换,维修成本太高。 “洪大爷”工作之余就将这些配件拿来研究,又查询相关书籍收集必备技术资料,几经摆弄,先后对单向阀、限压阀、真空发生器等五种常用配件进行了技术改进。单向阀采用是金属材料整体焊接,一次性使用。他将单向阀经过一次次改进,先是使用工作塑料材质丝扣拆装,再将塑料密封圈改为尼龙材质30度柔软性好的密封圈。使可重复使用、不易裂损。目前,他改造的单向阀已经使用两年多,无任何不良反应。从厂家购进的限压阀为铜质材料,不耐腐蚀,内部密封组件无厂家提供,也是一次性使用。洪斌使用尼龙材质30度硅胶密封圈,可清洗后重复使用;他还将真空发生器、泄压阀等进行材质、设计上的改造,让这些配件更多地节约成本,更耐用,更方便检修。还有一件更牛的事就是:洪斌还在集便装置试验台购回来之前,自行设计组装了一个简易的试验装置,对漏风漏水等故障有直观的判断。
“你真的是大爷!”面对他的一系列改造发明,大伙儿不得不竖起大拇指,“那是,这肯定不是浪得虚名”,洪斌一脸得意。
