The three machine integrated dehumidifier dryer (model EHD-1500) is a core temperature and humidity control equipment in industries such as injection molding and electronic manufacturing. It integrates the three functions of "dehumidification, drying, and feeding", and its stable operation directly affects the quality of raw materials and production efficiency.Daily inspections, as the first line of defense for preventive maintenance, can detect potential hazards in a timely manner through standardized inspection processes, ensuring the long-term efficient operation of equipment. The following provides a detailed explanation of the daily inspection points for the five core modules.

　　1、 Appearance and basic condition inspection

Firstly, observe the overall appearance of the three machine integrated dehumidifier dryer: whether the cabinet has obvious deformation, paint peeling or rust; Whether the door lock and observation window are well sealed. Check the wheels and horizontal adjustment feet - the equipment needs to be kept level, otherwise it may affect the stability of material transportation; Is the caster brake effective in avoiding accidental displacement during operation.

　　2、 Core functional module inspection

1. Dehumidification system: Check if the surface of the dehumidification wheel (or condenser) is clean. If dust or fiber accumulation is found, use a soft bristled brush to gently sweep it. Check the working status of the regeneration heater: Observe whether the regeneration temperature meets the standard through the control panel. If the temperature is abnormally low, it may indicate aging of the heating tube or malfunction of the temperature control sensor. At the same time, pay attention to whether the regeneration exhaust pipe is unobstructed to avoid the retention of humid and hot air.

2. Drying system: Check if the insulation layer of the drying material bucket is intact and if the filter inside the bucket is clogged. Confirm that the drying temperature is consistent with the set value. If the temperature is too high, it may cause the raw materials to deteriorate, while if it is too low, it will not effectively remove moisture.

3. Feeding system: Check whether the connection of the suction tube is sealed and whether the hose is damaged or bent; Check for foreign objects or clumps of raw materials in the hopper, and if necessary, clean and test the sound of the suction motor operation.

　　3、 Electrical and safety device inspection

Check if the control panel indicator lights are working properly and if the touch screen or buttons are responsive; Check if the grounding wire is secure to avoid the risk of electrical leakage. At the same time, test the emergency stop button function to ensure that the power can be quickly cut off in emergency situations.

　　4、 Operating parameter recording and trend tracking

Key data must be recorded for each inspection: current environmental temperature and humidity, drying bucket temperature, dehumidification wheel speed, and raw material moisture content. Suggest establishing a 'Daily Inspection Record Form' to continuously track parameter changes for 3-5 days. If dehumidification efficiency gradually decreases or heating energy consumption abnormally increases, it is necessary to promptly contact engineers for in-depth investigation.

　　5、 Inspection frequency and precautions

It is recommended to conduct a quick inspection every shift (8 hours) and a comprehensive inspection every week for routine inspections. Special attention should be paid to cutting off the power supply before operating internal components during inspection to avoid electric shock; Wear a dust mask when cleaning the impeller or filter to prevent inhaling dust.

Through standardized daily inspections, the failure rate of the three machine integrated dehumidification dryer can be reduced by over 40%, and the raw material qualification rate can be increased to over 99%. Only by implementing details in every inspection can equipment become the "silent but reliable" guardian of the production line.
