PET注塑模具除露机之五，瓶胚模除露机，空气除湿机，模具除露机七、设备日常维护与故障处理
PET 注塑模具除露机为工业级连续运行设备，常态化的日常维护是保证设备稳定运行和除露效果的关键，维护分为每日、每周、每月、每季度四个频次，操作简单。
PET injection mould dehumidifier is an industrial continuous operation equipment, and regular daily maintenance is the key to ensure the stable operation of the equipment and the dehumidification effect. The maintenance is divided into four frequencies: daily, weekly, monthly and quarterly, with simple operation.
每日需巡检设备运行参数，确认露点、温度、风压稳定，清理进风口过滤器和堵塞的喷嘴，检查风管与喷嘴是否漏气；每周需检查风机、电机的运行状态，清理设备表面粉尘油污。
It is necessary to inspect the equipment operation parameters daily to confirm that the dew point, temperature and air pressure are stable, clean the air inlet filter and blocked nozzles, and check whether the air duct and nozzles are leaking; inspect the operation status of fans and motors weekly, and clean the dust and oil on the equipment surface.
每月需校准各类传感器，保证检测精度，检查吹扫单元安装支架是否松动，校正喷嘴吹扫方向；每季度需检查分子筛吸附效果，活化失效分子筛，更换中效过滤器等易损件。
Calibrate various sensors monthly to ensure detection accuracy, check whether the mounting bracket of the purge unit is loose, and correct the purge direction of the nozzle; check the adsorption effect of the molecular sieve quarterly, activate the invalid molecular sieve, and replace wearing parts such as medium efficiency filters.
设备易损件有明确的更换周期：初效过滤器 3 个月更换一次，中效过滤器 6 个月更换一次，分子筛吸附剂 1~2 年更换一次，密封垫、喷嘴等易损件按需检查更换。
The wearing parts of the equipment have a clear replacement cycle: the primary efficiency filter is replaced every 3 months, the medium efficiency filter every 6 months, the molecular sieve adsorbent every 1~2 years, and wearing parts such as gaskets and nozzles are inspected and replaced as needed.
设备所有故障均会在触摸屏显示故障代码和描述，可快速排查处理：露点偏高多为分子筛再生不充分或过滤器堵塞，风压过低多为风机滤网堵塞或风管漏气。
All equipment faults will display fault codes and descriptions on the touch screen, which can be quickly investigated and handled: high dew point is mostly due to insufficient molecular sieve regeneration or filter blockage, and low air pressure is mostly due to fan filter blockage or air duct leakage.
除露机与注塑机联动失效，多为接近开关故障或信号连接线松动；送风温度偏差大，多为温度传感器故障或加热 / 制冷组件异常，现场可快速更换故障部件，恢复设备运行。
The interconnection failure between the dehumidifier and the injection moulding machine is mostly due to proximity switch failure or loose signal connection line; the large deviation of supply air temperature is mostly due to temperature sensor failure or abnormal heating/refrigeration components, and the faulty parts can be quickly replaced on site to restore equipment operation.
八、技术发展趋势
随着 PET 瓶胚注塑向高腔数、高射速、智能化方向发展，PET 注塑模具除露机正朝着智能化、定制化、节能化、多功能化和高洁净度的方向升级。
With the development of PET preform injection towards high cavity number, high injection speed and intellectualization, PET injection mould dehumidifier is being upgraded towards intellectualization, customization, energy saving, multi-function and high cleanliness.
智能化升级是核心趋势，设备将集成 AI 自适应控制和物联网技术，实时采集车间温湿度、模具温度、注塑节拍等数据，自动优化工艺参数，同时支持远程监控和故障预警，实现无人值守。
Intelligent upgrading is the core trend, the equipment will integrate AI adaptive control and Internet of Things technology, collect workshop temperature and humidity, mould temperature, injection cycle and other data in real time, automatically optimize process parameters, and support remote monitoring and fault early warning to realize unattended operation.
定制化与模具一体化设计将成为主流，吹扫单元将直接内嵌在模具型腔和顶针位，与模具同步设计、同步安装，吹扫更精准无死角，且不干涉注塑机动作。
Customization and mould integrated design will become the mainstream, the purge unit will be directly embedded in the mould cavity and ejector pin position, designed and installed synchronously with the mould, the purge is more accurate without dead angles, and does not interfere with the action of the injection moulding machine.
节能化将持续深度优化，在现有节能设计基础上，增加气流循环回收系统，将吹扫后的干燥气流部分回收再利用，同时采用石墨烯保温材料，进一步降低设备能耗 20%~30%。
Energy saving will continue to be deeply optimized, on the basis of the existing energy-saving design, an air flow cycle recovery system will be added to partially recycle and reuse the purged dry air flow, and graphene insulation materials will be adopted to further reduce the equipment energy consumption by 20%~30%.
设备将向多功能化发展，从单一除露升级为除露 + 模具保温 + 顶针润滑 + 模具清洁一体化，在吹扫除露的同时，实现模具温控、顶针自动润滑和模具表面料屑清理。
The equipment will develop towards multi-function, upgrading from a single dehumidification to an integration of dehumidification + mould heat preservation + ejector pin lubrication + mould cleaning, realizing mould temperature control, automatic ejector pin lubrication and mould surface scrap cleaning while purging and dehumidifying.
针对医药、食品级瓶胚的高洁净度要求，设备将**采用 316L 不锈钢材质，配备无菌高效过滤器和**涂层，增加气流洁净度监测模块，符合 FDA、GMP 等国际认证标准。
In view of the high cleanliness requirements of pharmaceutical and food-grade preforms, the equipment will fully adopt 316L stainless steel material, be equipped with sterile high-efficiency filters and antibacterial coatings, and add an air flow cleanliness monitoring module to meet international certification standards such as FDA and GMP.
