working principle

The deviation switch QJLP2-12-30 monitors the deviation status of the conveyor belt through the rollers in contact with it. When the deviation angle of the conveyor belt reaches 12 °, the roller pushes the internal micro switch and sends out a stop or alarm signal. If the conveyor belt returns to its normal position, the switch will automatically reset when the offset angle is less than 30 °, and the equipment will continue to operate normally.

Application scenarios

QJLP2-12-30 is widely used in industrial fields such as coal mining, metallurgy, chemical engineering, and power plants, especially in places where belt conveyor systems are prone to deviation. It can effectively prevent equipment failures and production interruptions caused by conveyor belt deviation, and improve the safety and stability of the production line.

Installation and Debugging

1. Installation locationIt is recommended to install QJLP2-12-30 on both sides of the conveyor belt, near the edge of the conveyor belt, to ensure proper contact between the rollers and the conveyor belt.
2. Electrical connectionConnect the wires according to the voltage requirements of the equipment, ensure the stability of the electrical connection, and set corresponding alarm or shutdown functions.
3. Angle adjustmentAdjust the angle settings of the rollers and switches according to actual application requirements to ensure that the switches can respond correctly when the conveyor belt deviates to the set angle.
4. Debugging and inspectionAfter installation, perform system debugging to test the sensitivity of the switch response and ensure that the equipment can alarm or shut down in a timely manner when offset occurs.

Maintenance and upkeep

1. Regular cleaningRegularly check and clean the dust and debris on the rollers and switches to ensure sensitivity and normal operation.
2. Electrical inspectionRegularly check the firmness of electrical wiring to prevent equipment failure caused by poor contact.
3. Mechanical component inspectionCheck the wear of rollers and other mechanical components, replace worn parts in a timely manner, and ensure stable operation of the equipment.

epilogue

The deviation switch QJLP2-12-30 is a high-performance conveyor belt protection device. With its high sensitivity and durability, it can effectively monitor the deviation of the conveyor belt, prevent equipment failure and production interruption. It is suitable for various industrial environments, providing reliable guarantees for the safe and stable operation of conveyor systems, and is an important equipment to ensure the normal operation of production lines.

Related Q&A FAQs:

1. What is the working principle of the deviation switch QJLP2-12-30?

QJLP2-12-30 monitors the deviation of the conveyor belt by installing rollers on both sides of the conveyor belt. When the offset angle of the conveyor belt reaches 12 °, the roller will trigger the internal micro switch, issue an alarm signal or trigger a shutdown. After the conveyor belt returns to its normal position, the equipment will automatically reset when the offset angle is less than 30 °.

2. What environments is QJLP2-12-30 suitable for?
