A thorough inspection before using the mixer is crucial for ensuring safe operation and production efficiency. The following are the inspection steps required before use:
1. External Inspection
Equipment Integrity: Check the mixer housing, impeller, inlet, and outlet for any damage or cracks.
Cleanliness: Ensure the equipment is clean inside and out, free of residual materials or dirt.
2. Electrical System Inspection
Power Connection: Check that the power cord is intact and that the plug and socket are making good contact.
Control System: Check that the control panel, buttons, and switches are working properly and that the display is clear.
Grounding Protection: Ensure the equipment is properly grounded to prevent electrical leakage.
3. Mechanical Component Inspection
Impeller: Check that the impeller is securely installed and that there is no deformation or wear.
Bearings and Seals: Check that the bearings and seals are intact and that lubrication is adequate.
Transmission System: Check for wear on belts, chains, or gears and ensure proper tension.
4. Lubrication System Inspection
Lubricating Oil: Check that the lubricating oil is sufficient and whether it needs to be replaced or replenished.
Lubrication Points: Ensure that all lubrication points have been properly lubricated.
5. Safety Device Inspection
Emergency Stop Button: Test that the emergency stop button is sensitive and reliable.
Protective Cover: Check that the protective cover is securely installed and free from looseness or damage.
Safety Interlock: Ensure that the safety interlock device is functioning properly to prevent the equipment from starting under dangerous conditions.
6. Operational Inspection
No-Load Operation: Start the mixer without any material to check for smooth operation and the absence of any abnormal noise or vibration.
Load Operation: Run the equipment after adding a small amount of material to check the mixing effect and equipment response.
