All operations should be conducted by trained personnel in accordance with safety regulations, and a maintenance log should be filled out truthfully after completion.
1. Pre-Startup Inspection (10-15 minutes)
Before powering on the equipment each day, perform a comprehensive visual and functional check to eliminate potential hazards in advance:
Appearance & Structure: Inspect the outer casing, connecting bolts, and protective covers of the equipment for cracks, deformation, or looseness. Focus on the joint areas of the “E-P5” and “G5-H” modules to ensure no oil leakage, air leakage, or material residue.
Power & Circuitry: Check if the power cord, plug, and terminal connections (especially for the “SN-D-N” control unit) are intact—no fraying, oxidation, or loose wiring. Verify that the emergency stop button and safety switches are in the correct (untriggered) position.
Fluid & Lubrication: Check the oil level, hydraulic oil level (for hydraulic components in the “E” module), and lubricant level of transmission parts. Ensure the fluids are clean (no turbidity or sediment) and replenish them to the specified scale if insufficient.
Auxiliary Components: Inspect hoses, filters, and sensors (e.g., pressure sensors in the “P5” module, temperature sensors in the “H” module) for blockages, damage, or misalignment. Replace the filter element immediately if it is clogged.
- In-Operation Monitoring (Continuous during working hours)
During the equipment’s operation, monitor its running status in real time to detect abnormal signs promptly:
Operating Parameters: Use the control panel of the “SN-D-N” unit to monitor key parameters (e.g., operating temperature, pressure, rotational speed, and current). If parameters exceed the normal range (refer to the equipment manual), pause operation immediately for troubleshooting.
Sound & Vibration: Listen for abnormal noises (e.g., grinding, knocking, or squealing) from the “G5” transmission module or “S-N” moving parts. Feel for excessive vibration at the equipment base—if detected, shut down the machine to check for loose parts or worn bearings.
Functional Performance: Verify that each module operates as intended: the “E” module (e.g., drive unit) responds smoothly to control commands, the “P5” pressure module maintains stable output, and the “SN” signal module transmits data without delay.
- Post-Shutdown Maintenance (15-20 minutes)
After stopping the equipment at the end of the workday, perform the following tasks to prepare for the next use:
Power & Energy Cutoff: Turn off the main power switch, disconnect auxiliary power supplies (e.g., for the “H” heating module), and release residual pressure in hydraulic/pneumatic systems to prevent accidental activation.
Cleaning: Wipe the equipment surface with a clean, dry cloth to remove dust, oil stains, or process residues. Use a soft brush to clean the air vents of the “SN-D-N” control box and the surface of heat sinks (avoid using water or corrosive cleaners).
Quick Wear Check: Inspect easily worn parts, such as seals in the “E-P5” module, friction pads in the “S-N” module, and contact points of switches. Mark parts that are severely worn (e.g., cracks, excessive wear) for replacement in the next periodic maintenance.
Log Recording: Record key information in the maintenance log, including:
Operating time and any abnormal phenomena during the day;
Results of pre-startup inspection and post-shutdown checks;
Fluid replenishment volume or minor adjustments made;
Unresolved issues (to be reported to maintenance personnel for follow-up).
- Special Notes
Safety Priority: Do not disassemble or adjust internal components (e.g., the “G5” gear module, “SN” signal board) during daily maintenance unless authorized—improper operation may cause equipment damage or personal injury.
Environmental Adaptation: If the equipment is used in a dusty, humid, or high-temperature environment, increase the frequency of filter cleaning and moisture-proof checks (e.g., for the “SN-D-N” control unit) to avoid component failure.
Manual Reference: All maintenance standards (e.g., fluid type, parameter ranges, wear limits) must comply with the official 350-E-P5-G5-H-E-S-N-N-SN-D-N Equipment Operation and Maintenance Manual—do not use non-compliant replacement parts or fluids.
