         screw extrusion machine maintenance process in generally separation is day maintenance and maintenance:

         day maintenance: 经常 property 例行工 as, equipment 运转工时, usually in 开车期间完 formed. focus/key point is machine, lubricated 各运动 parts, solid easy 松动 螺纹 parts, and 时检查, adjustment electrical machine, control table/sheet, as parts and tube/pipe and other.

        定期 maintenance: generally in extrusion machine 连续运转2500-5000h machine rear machine 进行, machine need understanding 体检查, amount, main/primary parts abrasion loss 情况, more already 达规定 abrasion loss degree parts, loss bad parts.

        两 types maintenance process versus versus formed, can or 缺. lower small introduction extrusion day maintenance in need attention/notes fine issues:

         day maintenance

         due to electrical control system for ring temperature degree and anti has very high requirements, will electrical system and production 现场隔离开, 并安装通风 or gas 扇, will electrical 控柜放 in easy inner, maintain inner 清洁, 通风, make inner temperature degree high 于40℃.

         extrusion machine 不允许空车运转, screw and machine 简轧毛. machine 启动空转时不允许 ultra- 100r/min;启动主 machine low speed, 启动主 machine rear has 无异常响动 rear again slow improve/increase machine speed process scope/range inner (can adjustment to most 佳状态 is good). new machine abrasion combined 时, electrical negative in 60-70%, positive use electrical most good ultra- 90%. attention/notes: extrusion machine 运转时若发生不 positive 常 声响时, 应立即停车, 进行检查 or 修理.

        开 machine 先开油泵, machine rear 关油泵; water in production process in maintain as 状态, can water 泵 运转, machine temperature degree upper rise machine inner material material separation understanding 炭化;主 electrical machine machine 石棉风罩需常清理, 避免灰尘 viscous more 堵塞风罩导致 electrical machine dispersion hot 不够因 hot 而跳闸.

         and 时清理 machine surface 尘垢, tool and material.

        严 anti metal or other material material in, loss bad screw and machine 筒. is anti iron material machine 筒, can in material material machine add material 口处装吸 magnetic parts or magnetic force 架, anti material 落入必 must material material 事先 筛.

         attention/notes production ring 境清洁, make waste mixed material material 堵塞 滤 sheet/plate, effect/influence products output/production volume, quality and increase machine retardant force.

         decrease speed use machine 说明书指定 lubricated 油, 并按规定 油面 high degree add liquid, liquid less, lubricated 不够, reduce parts use lifespan;油 liquid more, hot large, consumption can more, easy 变质, make lubricated 失效, formed loss parts rear 果. decrease speed 箱漏油部位应 and more 换密封垫(圈), ensure lubricated amount.

        定期 maintenance

        定期检查 machine surface and other solid parts has 无松动 and 时适当紧 solid. 传动箱 lubricated 油位应 and add or more 换(油箱底部 污垢应定期清理). for/regarding new machine generally 3 month need more one-time machine 油, rear semi year to year more one-time. for/regarding device and tube/pipe 应定期清洗(一 month one-time).

         extrusion machine decrease speed maintenance and generally standards decrease speed device same. main/primary is gears, bearings and other abrasion loss and 失效情况.

         heavy new 安装时请 attention/notes A, B两根 screw must is 原 位置, can more 换! in new combined screw upper machine rear, must use 手盘车, positive 常转动才 can low speed machine. screw machine long time use 时, has anti anti measures, screw 应悬挂放置. block use 火烧时, 火焰应 left right 移动, 边烧边清理. can 烧 头(发蓝戒者发红), more can will block water in.

        定期校 positive temperature degree control table/sheet, its adjustment positive property and control property.

         in machine inner use cooling water tank in must use water, anti formed water 垢堵死筒体 in cooling water 道, formed temperature degree 失灵. use in attention/notes 适当 添 add water amount, anti 止结垢. 如堵塞应 will 筒体换 lower specific repair, 无堵塞而出 water amount small table/sheet has water 垢, need will water tank water is dilute salt acid 迚行循 ring, 清垢至 positive again 换蒸馏 water. generally water tank in water used for cooling machine 筒, 而我们 通 自然 water is use cooling water tank. 定期查看 cooling water tank water 质, if 出现浑浊, and more 换.

        查看 electrical magnetic as is positive 常, has bad, has and more 换.

         temperature degree rise upper temperature degree upper rise drop lower can can in causes: day electrical is 否松落; add hot electrical appliances is as positive 常; electrical magnetic is as positive 常, and more 换发生形变 add hot device, solid 螺钉.

         and 时清理 true in 污垢, and gas inner material material make pipeline 畅通. true 空泵密封圈若出现 abrasion loss and more 换定期检查, 输出轴跳动肯定 is bearings loss bad and already fracture must more 换, gears 箱两输出轴 bearings abrasion loss heavy, must more 换箱体, more large fault/failure loss 失.

         for screw 转动 直流 electrical machine need focus/key point electrical abrasion loss and 接触情况, for electrical machine insulation electrical retardant value is in value above 亦应经常测 amount. in addition need 检查连接线 and its it parts is 否生锈, using/adopting measures.

        当 extrusion machine relatively long time use 时, in screw, machine 简, machine and other as surface coating upper anti lubricated 脂. small type screw 应悬挂于空 in or specialized inner, use block 垫平, screw deformation or 碰伤.

         extrusion machine cooling water tube/pipe inner easy water external easy 腐蚀生锈. maintenance 时应做认 true 检查, water more 会堵塞 tube/pipe 路, to cooling function, 锈蚀严 heavy water, therefore maintenance in must remove and anti drop temperature measures.

        指定专人 negative equipment maintenance. will 每次维护修理情况 detailed 记录列入 factory equipment tube/pipe 理档案.
