启闭机闸门喷砂处理的意义
Significance of Sandblasting Treatment for Gate of Hoist
启闭机闸门关系到水工建筑物的正常运行,除应满足一般起重机械的设计要求外,工作安全可靠和操作灵活方便具有特殊的意义。其喷砂处理是一道非常重要的工序,在处理的过程中要非常仔细,否则就会出现一些问题,进而影响到启闭机闸门的正常工作,甚至危害到施工人员的安危。因此。在启闭机闸门喷砂处理前,要了解其注意事项。据闸门启闭机橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 厂家解析:具体的注意事项如下。 1.启闭机闸门喷砂处理不允许在潮湿的金属表面上进行,露天作业应采取必要的防雨防潮措施。 2.启闭机闸门必须注意工件温度和空气环境湿度,当空气湿度较大或金属表面温度低于露点以下时应停止喷砂。 3.启闭机闸门经喷砂处理并检验合格的金属表面,在运输或防腐施工前应保持干净,避免沾染上水或油污杂质,并且不能直接用手接触金属表面,以防止局部返锈;已沾染上油污的金属表面必须用相应的有机溶剂进行处理,或者在去油处理后重新进行喷砂处理。 启闭机闸门 4.启闭机闸门喷砂处理后的金属表面,在空气湿度较大或周围有化学气体污染时,应在4小时内进行下道工序施工,在干燥洁净的环境条件下,应在24小时内进行下道工序施工 5.启闭机闸门喷砂工应戴防护用具,以保护身体不受飞溅磨料的伤害;在经喷砂处理后的大构件内进行防腐施工时,必须穿干净的工作服。
The gate of hoist is related to the normal operation of hydraulic structures. In addition to meeting the design requirements of general lifting machinery, it is of special significance to work safely, reliably and operate flexibly and conveniently. Sandblasting treatment is a very important process, in the process of treatment to be very careful, otherwise there will be some problems, which will affect the normal operation of the hoist gate, and even endanger the safety of construction personnel. Therefore. Before sandblasting treatment of hoist gate, it is necessary to know its precautions. According to the analysis of gate hoist manufacturer, the specific matters needing attention are as follows. 1. Sandblasting treatment of hoist gate is not allowed on wet metal surface, and necessary measures of rain proof and moisture proof should be taken in open-air operation. 2. Hoist gate must pay attention to workpiece temperature and air ambient humidity. Sandblasting should be stopped when air humidity is high or metal surface temperature is below dew point. 3. The qualified metal surface of the hoist gate after sandblasting treatment and inspection should be kept clean before transportation or anti-corrosion construction, avoid contamination with water or oil contamination impurities, and can not directly contact the metal surface with hands to prevent local rust. The metal surface contaminated with oil must be treated with corresponding organic solvents or sandblasted again after deoiling treatment. Hoist gate 4. When air humidity is high or there is chemical gas pollution around the metal surface after sand blasting, the next working procedure should be carried out within 4 hours. In dry and clean environment, the next working procedure should be carried out within 24 hours. 5. Hoist gate sandblaster should wear protective equipment to protect his body from splashing abrasives. Clean work clothes must be worn when anti-corrosion construction is carried out in the treated large component
