         injection molding machine lubricated system lubricated 油泵, lubricated 油(脂), tube/pipe, lubricated separation device, lubricated formed. lubricated 油经油泵 pressure shrink to separation device, again separation to lubricated 点, to lubricated injection molding machine 各运动部 parts 目. injection molding machine has 自动集 in lubricated system, electrical control formed, through electrical for pressure electrical appliances lubricated 状况.

         injection molding machine most Common has retardant lubricated system and amount add pressure lubricated system this types.

        定 retardant lubricated principle: (small type injection molding machine more using/adopting retardant 式) injection molding machine has retardant separation device, lubricated 油泵工 as 时, from export to separation device in generate pressure.

         lubricated pressure high retardant pressure 差时, lubricated 油会克服 retardant toward lubricated 点, to lubricated time is 止. separation device retardant large small different, separation to lubricated 点 油 amount is separation different. lubricated pressure in lubricated time 里达不 to pressure electrical appliances setting pressure value 时, machine 会报警.

        定 amount add pressure lubricated principle: (large type injection molding machine using/adopting amount 式) injection molding machine 配置 定 amount add pressure separation device, 当油泵工 as 时, to separation device add pressure, will amount separation device upper lubricated pressure toward lubricated 点, uniform lubricated 各部位.

        当 lubricated pressure to pressure electrical appliances pressure setting value 时, 油泵停止工 as, electrical 脑开始 lubricated 延时计时, separation device pressure 并自动 from in lubricated to upper 腔. lubricated 延时计时完 rear, again 次启动, 周而复始直止 lubricated time 结束.

        因 separation device 排油孔 can different, ensure lubricated 点 油 amount is separation 配. lubricated pressure in lubricated time 里达不 to electrical appliances pressure setting value 时, machine to 反馈信号而报警: lubricated 失败!

         introduction lubricated principle, lower combined day repair 笔记, understanding lower lubricated Common causes.

        1. 缺油报警

        油箱缺油时, lubricated 油泵工 as upper 油, pressure 不足, 导致报警. add semi lubricated 脂(lubricated 油), lubricated, again 无报警, fault/failure good. still has 报警, can can is 油泵吸入 空 gas, in has gas 体导致. 此时, 拆开油泵出油口, lubricated, 出油排 gas rear solid tube/pipe can.

         day machine in need formed lubricated good 习惯, lubricated use 情况, add or and 早发现 lubricated 隐患, can and other to 缺油报警 才 by add 油.

        2. 油箱 has 油报警

        油泵 滤网堵塞, 导致油泵吸不 upper 油, pressure 不足而报警. this type of fault/failure more is due to use 不洁 油 product or or poor 质油引起. lower upper 滤网, use copper 刷, 煤油清洗 滤网 and 吸油口, 清洗油箱, more combined lubricated 油(脂).

        油 pressure 不足报警. adjustment lower in right pressure 阀, use 平口起子顺时针 toward inner is large amount, 逆时针旋转 is small amount, 此时逆时调 small amount. 泄油口一定 need has 油溢流, can large, large, 出油口油 pressure small;没 has 油泄流, easy pressure large 而爆油 tube/pipe, 也不利于 again lubricated 时 起 pressure. 溢流阀口溢油适 in is 宜.

         false this type of methods still improvement, has 油泵泄 pressure 阀口里装 has elastic and elastic structure, can can elastic elastic by 杂质卡死, lower 清洗即 can.

        清洗滤网, adjustment pressure 阀, rear, although has lubricated from 油泵出油口流出, pressure table/sheet pressure 不足, machine 报警. very has can can 系油泵 long use waste 油, rear abrasion loss 泄漏, pressure 不足. repair or more 换油泵.

        笔者见 many is 一味节约 cost, use waste liquid pressure or lubricated 案例. 旧油没 has 经 精 fine 滤, remove water, simple lower, add use. liquid pressure 油杂质 more, degree 不够, upper to has lubricated function. accelerated and machine parts abrasion loss.

        3. 油 tube/pipe 漏油

        油路 certain tube/pipe 接头脱落 or loss 漏油, pressure electrical appliances 感应失败. rear, lubricated 观察, to 漏油点, repair tube/pipe.

        4. 油 separation device loss bad or 堵塞

        导致 separation device pressure electrical appliances 感应失败, use 煤油清洗 separation device rear can adjustment amount add pressure separation device upper adjustment 螺母, make shrink can pressure to electrical appliances 开关. still 不见效, more new separation device.

        5.  pressure electrical appliances loss bad

         use use table/sheet testing 开关, bad more new.

        6. 信号线断路 or defect

         use use electrical table/sheet to fault/failure 点, repair loss bad 线路, or solid 接头端子.

        7.  parameters 设置不当

         production process in lubricated 失败报警, 检查泵, 油, 线路, 无异常. electrical 脑信号时, electrical control device 无信号输出, lubricated still reaction, this can can is parameters issues. lubricated setting value small, lubricated already to its setting value, can 凭密码进 system 画面, to lubricated 模数, 设 数 value large can.

        定 amount add pressure lubricated time is lubricated time, lubricated time 也应适当 long 一, has time ensure pressure electrical appliances pressure, from 而避免因设置 lubricated time short generate 误报警.

         its machine front already has combined 理设置, 不建议不赞 formed more electrical in related lubricated parameters 设置, effect/influence machine lubricated.

         summary:

         lubricated fault/failure its difficult, if 我们不 heavy 视, 不积极处理 fault/failure, simple in electrical upper lubricated function or short lubricated 检知报警信号(it is Ov+信号线). although machine 不报警, can as, its 隐患极 large. 久而久之, effect/influence machine parts property can and lifespan. Common copper sleeve/set, 铰销, 十字架 abrasion loss deformation, basic upper is due to lubricated defect 引起 严 heavy fault/failure.

        我们平时爬 upper machine upper repair equipment or machine 械手时也 need lower 留情, need 野蛮乱踩 bad lubricated tube/pipe, 开关. 笔者曾见 certain workshop 27台 injection molding machine in has 3台 machine lubricated system also in positive as, its full short 接, lubricated already formed 摆设. also has injection molding machine large 铰销限位螺 filament, pressure block already fracture, already 脱离出, scratch 哥林柱伤痕累累, iron 屑一堆.

         lubricated defect machine abrasion loss, loss bad is 一 渐变 process. positive 谓, 树叶不 is 一天变黄. use combined lubricated 油(脂), 定期添 add, 主动观察巡查, lubricated fault/failure its very less very less.

        笔者 understanding to in many Imported Brand injection molding machine lubricated frequency rate and lubricated amount is 动态变化. it is electrical control system according to clamping force, injection molding cycle, mold opening comprehensive 计算 实施动态 lubricated. although different Brand injection molding machine lubricated structure has different, its lubricated principle 一样, repair methods large small 异.
