Product Description of Deviation Switch FPK-20-35

Product Overview

The deviation switch FPK-20-35 is a safety protection device used to detect and prevent conveyor belt deviation. This device is mainly used in belt conveyor systems in industrial production. By timely detecting the deviation status of the conveyor belt, it avoids equipment damage, production accidents, and safety hazards caused by belt deviation.

working principle

The deviation switch FPK-20-35 operates based on the principle of mechanical limit triggering. When the conveyor belt deviates, the offset of the belt body touches the roller or sensing rod of the deviation switch, causing the switch to act. This action will trigger an alarm signal or directly shut down the control system to avoid more serious equipment failures or safety accidents.

Application scenarios

The deviation switch FPK-20-35 is widely used in belt conveyor systems in industries such as mining, steel, power, chemical, and ports, especially in situations where high conveying accuracy is required and the operating environment is complex.

Installation and Debugging

1. Installation locationIt should be installed in areas where the conveyor belt is prone to deviation, usually at the head, tail, or middle of the conveyor.
2. Installation heightEnsure that the roller or sensing rod of the deviation switch is parallel to the edge of the conveyor belt and maintains an appropriate distance.
3. Wiring methodConnect the switch output signal to the control system or alarm device according to the wiring diagram in the product manual.
4. Debugging methodDebug the system separately under no-load and full load conditions to ensure accurate and error free switching actions.

Maintenance and upkeep

• Regularly check whether the fixing bolts and sensing rods of the deviation switch are loose or damaged.
• Clean the dust and debris on the surface of the switch and sensing parts to maintain the sensitivity of the device.
• Check if the electrical connections are secure to avoid misoperation caused by poor contact.

matters needing attention

• Avoid violent impact on the switch device during installation to avoid affecting its sensitivity and service life.
• Debugging or maintenance operations should not be carried out while the machine is still in operation to avoid safety accidents.
• If the switch action is found to be insensitive, it should be checked and the fault should be eliminated immediately.

The deviation switch FPK-20-35, as a key safety device in the belt conveyor system, has the characteristics of simple operation and stable performance, and is an indispensable equipment for ensuring industrial production safety.

Related Q&A FAQs:

1. Can the deviation switch FPK-20-35 be installed on any type of belt conveyor?

Yes, the deviation switch FPK-20-35 is designed to be suitable for various types of belt conveyors, whether it is a light or heavy load conveying system, it can be used. Just adjust and install according to the width, speed, and installation environment of the conveyor belt to ensure that the sensing roller of the switch is aligned correctly with the edge of the conveyor belt.

2. Can the action angle of FPK-20-35 deviation switch be adjusted?

The standard operating angle of the deviation switch FPK-20-35 is ± 20 °, and it is generally not recommended for users to adjust it themselves. This angle has been designed and optimized to trigger an alarm or stop operation when the conveyor belt deviates slightly. If there are special requirements for the action angle, it is recommended to contact the manufacturer for customization.

3. How does the deviation switch FPK-20-35 perform in harsh environments?

The deviation switch FPK-20-35 is made of high-strength alloy steel material and has an IP65 protection level, which can effectively prevent dust and water. It is suitable for long-term use in harsh environments such as high humidity and high dust. In addition, its working temperature range is wide (-30 ℃~+70 ℃), ensuring stable operation even under extreme weather conditions.
