1、卧式砂磨机操作规程定稿编号LCGY-004工艺守则第1张共5张卧式砂磨机操作规程一、本工艺适用于车间卧式砂磨机操作的技术指导性规程。二、砂磨机结构由主机,含单端面机械密封装置及与其相配套的润滑、冷却油路系统,、筒体、分散器、筛圈-动态分离复合分离器、内圆弧齿轮泵、压力和温度的监控系统、机身、辅助支架等部分组成.在筒体内装直径为1-3厘米的玻璃珠或错珠作为分散介质。三、砂磨机的分散原理1 .卧式砂磨机的主轴水平布局按一定的间距装有7-9个分散盘分散轴由主电动带动高速转动,从而使筒体内的分散介质作剧烈运动，同时经预混合的漆浆从送料系统送入筒体。研磨分散进行过程中物料从一端向另一端流动颜料的聚集体和
2、附聚体在这里受到高速运动的分散介质的剪切和冲击作用，从而在分散盘之间得到分级分散。当漆浆和分散介质的混合物到达筒体另一端时,分散介质为筛圈-动态分离复合分离器截留,漆浆溢此从而完成一次分散。因漆浆受到剪切和冲击作用时会引起温度升高,因此研蘑筒体设有冷水夹套,通水进行冷却。2 .影响砂磨机分散效率的因素：a.主轴转数:砂磨机的分散效率和分散转数成正比.b.砂磨介质：一般情况下产品要求的细度越细,使用的研磨介质的直径也相应小一些.因介质直径,通常在1.5-2.5mm之间，愈小,球体之间相应碰撞发生剪切作用的机率越大,研磨分散效率也会提高。C.研磨介质的装填量:一般介质的装填量越大,研磨分散效率越高
3、。但因介质比重,漆浆稠度和研磨机主轴功率的限制,装填量不能过大,否则启动困难,通常卧式砂磨的装砂量为筒体有效容量的85,。如出料温度过高应减少装填量若出料温度过低为了提高研磨效率而应适当增加装填量这里出料温度的高低与冷却水的温度与耗量有密切的关系单介质的装填量也是不能忽视的因素。d.操作温度:尽管砂磨机都有冷却夹套,但是操作温度均高于室温,温度对颜料分散将有较大影响。在漆浆粘度随温度上升而减少的情况下,可采用40-50度的温度操作，以提高功率。e.预混合程度:漆浆的预混合好坏,将直接影响砂磨机的正常运行和分散效率高低。因此,应注意漆浆预混阶段的充分润湿，以保证砂同分散效率的发挥。编制资料来源实

5、间歇性的微动运转以减少清洗液的阻力如此循环两、三分钟后拧开放液塞放出筒内的清洗液再重复一遍。切忌才长时间用溶剂清洗否则将严重磨损相关零部件并导致研磨介质破碎。在研磨某些易于干结前渗透性产品时每磨完一批料后应立即对物料系统进行清洗若不及时清洗将引起物料在出料筛圈、机械密封周围干结从而导致出料筛圈堵塞和密封失效的严重后果。4 .使用操作a.启动送料泵开始时应将进料速度跳到较低值。b.打开冷却进水阀。c.启动主机。出观察进料、进水、润滑油运行状况检查仪表的限定值。?.送料泵：a.由于工况条件特殊物料中有时会有异物,棉纱头、钉子等,混入应尽量避免从而将泵卡死有鉴于此在泵轴的联接处设有安全剪切键材质尼龙
