Shanghai Daoqin Plastics Co., Ltd.

不论 is Imported also is Domestic injection molding machine tool has below/following features:

injection molding machine solid assets investment large, production large, consumption raw materials more, production rate high, value large. is types efficiency relatively high production 组织形式.

injection molding machine machine 械, liquid pressure, electrical appliances, specialized sleeve/set parts and other, according to injection molding processing process technology need, has machine combined in 一起, 自动化程 degree high, versus between 关联紧密; injection molding machine can 3班24h连续运转. injection molding machine certain parts fault/failure, will 导致停 machine.

injection molding machine upper although as simple, less, injection molding machine tube/pipe and repair technology content high, as amount large. therefore need ensure injection molding machine 经常处于完 good 状态, must add strong/high injection molding machine tube/pipe as, control injection molding machine fault/failure 发生.

以达 to reduce fault/failure rate, decrease/reduce repair use, long use lifespan 目. injection molding machine fault/failure, generally is injection molding machine or system in use in or reduce its function parts or phenomenon. injection molding machine is enterprise is meet/satisfy injection molding products production process requirements 而配备.

injection molding machine function it in injection molding products production active in in value and for injection molding production ensure degree. in 现代化 injection molding machine production in, due to injection molding machine structure complex, 自动化程 degree very high, liquid pressure, electrical and machine 械 联系 non 常紧密, injection molding machine fault/failure, that is local 失灵, 都会造 formed injection molding machine 停产. injection molding machine fault/failure effect/influence injection molding product amount and quality.  

is ensure fault/failure analysis and troubleshooting fast 捷, has 效, must 遵循一定 程序, this type of large lower:

第一步 maintain 现场 情况 lower 进行症状 analysis

1.询问操 as 人员

发生 what fault/failure? in what lower 发生? what 时候发生?

injection molding machine 巳经运行 more 久?

fault/failure front has 无任何异常 phenomenon? has 何声响 or light 报警信号? has gas or 异味? has 无误操 as （ attention/notes methods ）?

control system as is positive 常? as has 无变动? in as is has 特殊困 difficult or 异常?

2.观察整 machine 状况, 各项运行 parameters

has obvious phenomenon? parts has retardant or loss 伤? liquid pressure system has 否松动 or 泄漏? electrical has 无破裂, scratch or 烧毁?

injection molding machine parameters has 何变化? has obvious dry 扰信号? has obvious loss bad 信号?

3.检查监测指示 plant/unit

检查 has value is positive 常, pressure table/sheet and its it table/sheet 读数, high degree 情况.

检查 滤 device, device and plant/unit, as or device is positive 常.

4.点动 injection molding machine 检查（ in conditions lower ）

检查间歇情况, 持久情况, fast or slow 进时 情况, in this lower is effect/influence 输出, is can can loss bad or its it 危险.

第二步 检查 injection molding machine （包括 parts, parts and 线路）

1. utilizing 感官检查（继续 in-depth process ）

看: and base/seat has 无异常, electrical machine or 泵 运转 is positive 常, control adjustment is positive 确, has 无起弧 or 烧焦 痕迹, filament good bad, liquid has 无泄漏, lubricated is 否畅通 and other.

摸: injection molding machine 振动情况, 元（组） parts hot degree, tube/pipe temperature degree, machine 械运动 状态.

听: has 无异常声响.

嗅: has 无焦味, odor, its it 异味.

查: parts and 位置变化, injection molding machine property can parameters 变化, 线路异常检查.

2.评定检查结果

评定 fault/failure is positive 确, fault/failure is to, 各项检查结果 is 否一致.

第三步 fault/failure 位置 确定

1.识别 system structure and testing methods

查阅 injection molding machine 说明书, injection molding machine is types structure, use what methods testing, need what testing 手段, can can obtain what testing parameters or property can parameters, in what as conditions lower testing, must which safety measures, is need as can 证.

2. system testing

using/adopting most combined system structure technology testing. in combined testing 点, according to and 反馈 结果 and positive value or property can standards comparison, can 疑位置.

第四步 修理 or more 换

1.修理

查找 fault/failure causes, for injection molding machine fault/failure 进行修理并采取预 anti measures; related parts, anti fault/failure expand dispersion.

2. more 换

positive assembly debugging more parts, 并注意 related parts. lower parts 进行修理 or waste.

第五步 进行 property can 测定

1.起动 injection molding machine

零部 parts assembly debugging rear injection molding machine, 先手动（ or 点动）, rear 进行空载 and negative 载测定.

2. adjustment negative 载变化 speed degree low to high, negative small to large, system pressure most high can ultra- 140kg/cm2, 按规定 standards property can.

3. expand large property can experiment/testing scope/range

according to need, local to system expand large property can experiment/testing scope/range. attention/notes non fault/failure system 运行状况. property can meet/satisfy requirements 则交付 use, meet/satisfy requirements heavy new fault/failure 部位.

第六步 记录并反馈

1.收集 has value material and data

如 injection molding machine fault/failure time, fault/failure phenomenon, machine time, 修理工时, parts, 修理效果, solution issues, 结算费 use and other, 按规定 requirements 存入档案.

2. statistics analysis

定期 analysis injection molding machine use 记录, analysis machine loss 失, 修订备忘目录, decrease/reduce repair as focus/key point measures, research fault/failure mechanism, 提出改进 measures.

3.按程序反馈 has fault/failure upper tube/pipe 部门, 并反馈 to injection molding machine manufacturing mono 位.
