1, ratio/proportion and electronics large sheet/plate ratio/proportion amount and ratio/proportion pressure 阀统称 ratio/proportion 阀. it has and 油摯线圈组 formed. it main/primary function is through 油摯线圈受 electrical large small control 阀 流 amount how much. 而油摯线圈受 electrical and 阀体流 amount 开放程 degree is 按一 定 ratio/proportion property 关系而变化. injection molding machine injection molding 预置叁数 rear, through CPU in 央处理 device and electronics large sheet/plate rear, injection molding machine injection molding as pressure and amount ratio/proportion control. specific can use electrical DPCA and DSCA electrical table/sheet 显 示 ratio/proportion property 关系. specific 叁数如 lower. S=00 时, ratio/proportion amount DSCA electrical electrical table/sheet 显示 200Ma; S=99 时, ratio/proportion amount in DSCA table/sheet upper 显示 680Ma P=00 时, ratio/proportion pressure in CPCA table/sheet upper 显示 0mA; P=99 时, ratio/proportion pressure in DPCA table/sheet upper 显示 800Ma. versus for pressure table/sheet in 15~145kg/CM2 scope/range inner property 变化. DSCA electrical table/sheet upper and DPCA electrical table/sheet upper electrical 流叁数也就 is ratio/proportion amount, ratio/proportion pressure 油摯阀线圈 electrical pressure 变化索取. it 受控于 electrical CPU in 央处理 device and electronics large sheet/plate control. electronics large sheet/plate electrical pressure control ratio/proportion amount, ratio/proportion pressure 阀. made ratio/proportion amount, ratio/proportion pressure 阀 线圈吸 combined degree control pressure and amount. 2, ratio/proportion and electrical CPU in 央处理 mono ratio/proportion and electrical CPU in 央处理 mono is versus 连, versus 连, is 一体, 共同 完 formed injection molding as. its process is: 叁数预置—— > electrical 脑处理—— > electronics large sheet/plate —— > ratio/proportion amount —— > injection molding 各 动 as. understanding ratio/proportion and electrical CPU in 央处理 mono 元 关系, for repair as provide based on. 预置叁数 make data electrical CPU in 央处理 mono 元, for 叁数 运算 and 处理, will data amount through D/A device 转 换 formed amount 信号. 而该模拟 amount also ratio/proportion large rear, again pressure, amount most high control and pressure force, amount most low control 4 electrical device control 调校, 输出信号 幅 value in in 0~3V scope/range inner 变 化. in repair process in, generally good rear can upper machine as, adjustment pressure most high control electrical device, 否 则会改变工 as 点, to lower grade control belt/tape difficult. electrical 脑输出 control as is electronics large sheet/plate 输入信号, 经 整形, comparison, 反馈, large and 隔离传送 control rate tube/pipe, again 驱动油摯阀 and ratio/proportion amount, ratio/proportion pressure 阀线圈. 而线圈受 electrical large small also control ratio/proportion 阀 流 amount 开放程 degree 即线圈 electrical pressure and ratio/proportion amount 呈 线 property 关系. 3. speed degree and pressure and adjustment methods in positive 常情况 lower, injection molding machine amount and pressure already 经 严格 调校, generally need again 调. in 特殊情况 lower, need heavy new electrical CPU upper pressure and amount control electrical device. （ 1 ）数控 pressure property ratio/proportion control methods 1, electrical CPU mono upper 四 “流 amount and pressure control ” electrical device 位置. 2, parameters grade speed degree to 50, pressure pressure to 00 3, 启动油泵 electrical machine, in solvent temperature degree to solvent temperature degree 时, 按手动射胶键, make screw to 底, pressure pressure force table/sheet 应指示一 low 于 20 公斤 pressure value. can use pressure most low control electrical device adjustment, 反时针旋 转, can make pressure reduce. 4, can parameters will pressure grade increase, pressure table/sheet 指示应按 ratio/proportion increase, pressure value pressure pressure to 达 50 时, 90 时, pressure table/sheet in 误差 2.5 公斤 below/following, ultra- adjustment most low electrical device. 5, 停止输入射胶信号, heavy upper 述 2, 4 steps, utilizing pressure 数控数 value as 检查点. commonly used 50 and 99, its in 一 检查点 99 达 to pressure 指示, 而另一 检查点 50 pressure 指示误差不 ultra- （ 需 pressure 指示） 2.5kgf/cm2, use again adjustment. need in pressure value is 00 时, pressure table/sheet pressure 指数不 can high 于 20kgf/cm2, generally in 5~15kgf/cm2 between. 6, is in pressure 99 检查点 inner adjustment pressure time long, 引起油 temperature hot or electrical machine 载, hot electrical appliances as, need speed positive 确. hot electrical appliances need and other 2min rear, hot machine electrical appliances metal sheet/slice rear, pressure force value low rear, again hot machine electrical appliances 复位按键, adjustment. 7, adjustment pressure in 05~10 and 90~99 时, pressure table/sheet can can has combined property ratio/proportion pressure 指示, this is positive if 误差额不 high 于 6kgf/cm2 则不 need adjustment.. 8, injection molding machine type type different, most high system pressure different. most high system pressure is 145kgf/cm2 时, in pressure to 50 时油 pressure table/sheet 指示应 in 72.5kgf/cm2. 而误差不 ultra- 2.5kgf/cm2 则不 need 调校. （ 2 ）数控 speed degree property ratio/proportion control methods 1, lower mold, 取消特 fast 琐模操 as 2, low pressure 琐模. 3, upper safety 门. 4, high speed speed degree to 0 数 value, high speed mold opening speed degree and low speed mold opening speed degree to 40 数 value. 5, 启动油泵 electrical machine, use 手动操 as methods mold opening. mold opening rear, again 按琐模, this 时动模 sheet/plate 不应移动, in will high speed speed degree to 10. in 调时, sheet/plate has slow 移动. 6, in electrical CPU in 央处理 device electronics sheet/plate upper, use speed degree most low control electrical device adjustment, upper steps to steps 5 requirements. speed degree adjustment 适当时若 high speed 琐模调 to 10 时, sheet/plate slow slow 移动. to 00 时, sheet/plate 会停止移动, again 转回 10 时, sheet/plate slow slow 开始移动. if sheet/plate 移动时, 震 动幅 degree large, 应检查 is 否取消特 fast 琐模. 7, if high speed speed degree is 00 时, sheet/plate 移动, can W1 反时针 direction 转动, 直至模 sheet/plate 停止移 动 is 止. if speed degree is 10 时, 动模模 sheet/plate 不移动, can W electrical device 顺时针 direction 转动, 直至 模 sheet/plate is 止. 8, heavy new adjustment low pressure 琐模 位置 预调 time. 4, more electronics large sheet/plate and methods generally is will loss bad sheet/plate from 插入式插 base/seat in lower, upper new electronics large sheet/plate. new sheet/plate upper rear, also need add 以调校, maintain pressure and speed degree property ratio/proportion control, methods lower: 1, lower loss bad electronics large sheet/plate, upper new sheet/plate, 插入插 base/seat, solid electronics electrical sheet/plate. 2, electrical sheet/plate. 不开油泵, 按手动射台按键, 显示灯亮, electrical DSCA and DPCA electrical table/sheet is has electrical 流, 看面部 pressure table/sheet is has pressure. positive DSCA table/sheet has 400MA electrical 流, DPCA table/sheet upper has 450MA can. 若达不 to, can selection electronics large sheet/plate in pressure. amount electrical device coarse 调, make electrical to. 3, solvent add temperature. to material temperature 时, 开启油泵 electrical machine, 按手动射胶, will screw 顶底. 停掉油泵. 4, 数控四段射胶 speed degree to 00, pressure pressure 预置 00, again 按手动射胶, 看数控流 amount DSCA electrical table/sheet and DPCA electrical table/sheet upper 指示. DSCA 指示应 is 200MA; DPCA electrical table/sheet upper is 0MA. has can use electronics large sheet/plate upper amount micro or pressure micro electrical device 进行调校, 顺时针 direction can increase add electrical table/sheet upper 指示数 value, 反之侧 reduce 指示数 value. 5, 数控四 grade speed degree to 99, pressure pressure to 99 （因 equipment different, most large pressure different. this 里 99 is most large pressure ）, 按手动射胶, DSCA electrical table/sheet electrical 流指示应 is 680MA, DPCA electrical table/sheet upper 指示应 is 800MA. 若达不 to can use electronics large sheet/plate upper amount micro and pressure micro 调进行调校. 6, upper steps method to can use heavy new adjustment electrical CPU 信号输出幅 value, heavy 调. 7, to upper requirements, can will grade speed degree to 50, pressure to 99. 启动油泵 electrical machine, 按手动 射胶, 观察油 pressure table/sheet pressure is in equipment most large value upper. 如达不 to, can adjustment electrical CPU mono upper most large pressure control electrical device, make its to. 8, can again 预置四 grade speed degree 50, pressure pressure 50 （ most large pressure semi ）, again 按手动射胶, pressure table/sheet pressure is again semi 位置, 校验一 lower pressure control property degree.
