The ZLJ series belt vulcanizing machine is primarily used for the hot vulcanization process of rubber conveyor belt joints and must be operated in accordance with specifications to ensure safety and effectiveness. Below are the detailed usage instructions and precautions:
Operation Procedure
-
Equipment Inspection and Preheating
-
Check the insulation resistance of the heating plate (must be below 50 MPa before use). Power on to dry until the insulation value meets the standard.
-
After connecting the power supply, set the target temperature (usually 145°C) and initiate heating. The heating process takes approximately 20 minutes.
-
-
Joint Assembly and Fixing
-
Place the prepared conveyor belt joint on the lower heating plate. Secure both sides with spacer blocks and adjust the spacing to match the belt width.
-
Install the insulation board, upper heating plate, and screws. Tighten the nuts evenly (apply a torque of approximately 294 N·m).
-
-
Pressure and Temperature Maintenance
-
Connect the high-pressure water pipe to the pressure pump. Set the pressure to 0–2 MPa and activate the electrical control box.
-
Once the temperature reaches 145°C, maintain it at this level. The vulcanization process typically takes about 1 hour.
-
-
Completion
-
After the alarm sounds, turn off the power supply. Remove the joint and check the bonding strength.
-
Precautions
-
Avoid touching heated components during operation to prevent burns.
-
Keep the equipment dry. For outdoor operations, take measures to protect against rain and moisture.
-
Perform regular maintenance to ensure the proper functioning of pressure and temperature sensors
