working principle

The P-LJ2 deviation switch is installed on both sides of the conveyor belt, and detects the lateral deviation of the conveyor belt to determine whether the system is abnormal. When the offset angle reaches the set value, the switch triggers and outputs a signal to the control system, controlling the conveyor belt to stop running or issuing an alarm signal to prevent further escalation of the accident.

application area

• Mining industryUsed to monitor belt deviation in ore or coal transportation to ensure safe system operation.
• Metallurgical industryUsed for deviation monitoring of material conveying systems in metallurgical industries such as steel mills and ironworks.
• Power industryBelt deviation monitoring for coal conveying systems to prevent equipment damage caused by belt deviation.
• Chemical industryEnsure the safety of material transportation in chemical plants and prevent production interruption or material leakage caused by conveyor belt deviation.

Installation and Debugging

1. Installation locationInstalled in suitable positions on both sides of the conveyor belt to ensure that the equipment can monitor the offset status of the conveyor belt.
2. Adjust the detection angleBy adjusting the knob to set the trigger angle of the switch, ensure that the device adapts to specific work requirements.
3. Connect the power supply and control systemConnect the wires correctly according to the electrical wiring diagram to ensure normal power and signal output.
4. test runAfter installation and debugging are completed, run the conveyor belt system, simulate the deviation situation, and confirm that the alarm and shutdown functions of the deviation switch are working properly.

Maintenance and upkeep

1. Regular inspectionCheck the appearance, wiring, and internal components of the deviation switch once a month to ensure that there is no looseness or damage.
2. Equipment cleaningClean the exterior of the equipment, especially the sensing components, to prevent dust and debris from accumulating and affecting equipment detection.
3. Lubrication and maintenanceFor the moving parts such as rollers of the equipment, regular lubrication and maintenance should be carried out to reduce friction and wear, and extend the service life of the equipment.

matters needing attention

• Pay attention to protection during installationEnsure that the deviation switch is installed in a suitable position on both sides of the conveyor belt to avoid equipment failure due to vibration or external forces.
• Regularly check and adjust the angleEnsure that the detection angle matches the working status of the on-site conveyor belt to avoid false alarms or untimely detection.
• Attention to usage environmentTry to avoid exceeding the temperature and humidity range specified by the equipment to ensure stable operation.

conclusion

The P-LJ2 deviation switch is a safety detection device with stable performance and sturdy structure, suitable for belt conveyor systems in multiple industrial fields. Its sensitive detection capability and simple operation make it an ideal choice for ensuring the safe operation of conveying systems. By proper installation and maintenance, the service life of equipment and the operational efficiency of the conveying system can be effectively improved.
