instructions:

1. installInstall the PWG-20-35 deviation switch horizontally or vertically on the belt frame, ensuring that the roller can touch the edge of the belt. When the belt deviates, the roller of the switch will also deflect, triggering the switch action.
2. debuggingAfter installation, the position and angle of the switch should be adjusted to ensure accurate response to belt deviation, and appropriate alarm or shutdown points should be set.
3. maintainRegularly check the working status of the deviation switch, clean the dust and foreign objects on the roller, and maintain its sensitivity and reliability. Especially in harsh environments, the frequency of inspections should be increased to prevent equipment failures.

matters needing attention:

• During the installation process, avoid impacting the switch housing or internal structure to avoid affecting its performance.
• When used in extreme temperatures or corrosive environments, it is essential to regularly inspect and maintain the equipment to ensure its proper functioning.
• During debugging and maintenance, the manufacturer's operating manual should be followed to avoid misoperation and equipment damage.

Summary:The PWG-20-35 deviation switch plays an important protective role in the belt conveyor system. With its high sensitivity, durability, and flexible installation characteristics, it can effectively prevent equipment damage and production interruption caused by belt deviation. Proper installation and maintenance can not only extend the service life of equipment, but also ensure the safety and stability of production.

Related Q&A FAQs:

1. What type of belt conveyor can the PWG-20-35 deviation switch be installed on?

The PWG-20-35 deviation switch is suitable for various types of belt conveyors, including conveying systems in mining, metallurgy, power, and chemical industries. It can be installed on horizontal or vertical belt racks to adapt to different belt conveyor configurations, ensuring timely detection and alarm when the belt deviates.

2. How does the PWG-20-35 deviation switch perform under different environmental conditions?

The PWG-20-35 deviation switch has strong environmental adaptability, and its housing is made of aluminum alloy material with a protection level of IP66, which can effectively resist the intrusion of dust and water droplets. It is suitable for use in harsh conditions such as high temperature, low temperature, and humidity, with ambient temperatures ranging from -30 ℃ to+70 ℃. However, in extreme work environments, regular inspections and maintenance are particularly important to ensure the proper functioning of equipment.

3. What is the working principle of PWG-20-35 deviation switch?

The PWG-20-35 deviation switch monitors the running status of the belt through the built-in roller. When the belt deviates or runs off, the roller will rotate or tilt accordingly, triggering the mechanical contacts inside the switch. The opening and closing of the contact will send a signal to notify the control system to take corresponding measures, such as issuing an alarm or stopping the equipment. This mechanism can quickly respond to the offset of the belt, ensuring the safe operation of the equipment.
