working principle:
The YF/PK-20-35 deviation switch is installed on both sides of the conveyor belt, mainly used to monitor the deviation of the conveyor belt. When the belt deviates, it touches the action lever of the switch, causing the micro switch inside the switch to actuate, issuing an alarm signal or triggering the shutdown control. This can effectively prevent equipment damage and safety accidents caused by deviation.

Installation and Debugging:

1. Installation locationIt is recommended to install the switch in areas where the belt is prone to deviation, such as the middle of the conveyor belt or near the tensioning device. Ensure that the installation position of the switch is stable and avoid displacement due to vibration or external forces.
2. Adjustment stepsAfter installation, it is necessary to adjust the action angle of the switch, usually between 20 ° and 35 °, to ensure that the alarm can be triggered when the belt deviates slightly.
3. Fixing and wiringUse appropriate fasteners to install the switch on the bracket and wire it correctly according to the electrical drawing to ensure the stability of the electrical connection.

Application scenarios:

• Mining industryUsed to monitor the deviation of ore or coal conveyor belts and ensure the safety of the production process.
• Power industryDetecting belt deviation in the fuel delivery system to protect the safe and stable operation of electrical equipment.
• Metallurgical industryMonitor the deviation of high-temperature material conveyor belts to prevent equipment wear and production accidents.
• Logistics and portsUsed for monitoring the deviation of bulk cargo conveyor belts to prevent damage to goods and equipment failures caused by deviation.

Maintenance and upkeep:

1. Regular inspectionRegularly inspect the mechanical and electrical components of the deviation switch to ensure that all parts are working properly.
2. cleanKeep the switch and its surrounding environment clean to prevent dust and debris from affecting the sensitivity of the switch.
3. functional testingRegularly test the response of the switch by simulating the deviation state of the belt to ensure that it can alarm in a timely manner during actual use.

matters needing attention:

• During installation and debugging, avoid applying excessive external force or vibration to the switch to prevent damage to the internal structure.
• When adjusting sensitivity, it should be based on the actual operating status and application requirements of the conveyor belt to avoid false alarms or missed alarms.
• Be sure to operate in a power-off state to ensure safe operation.

Conclusion:
The YF/PK-20-35 deviation switch is an efficient and reliable belt conveyor protection device. Its high sensitivity detection and sturdy and durable design have made it widely used in various industries such as mining, power, metallurgy, etc. Through accurate monitoring and timely warning, YF/PK-20-35 has improved the safety and operational efficiency of the conveying system.
