The HRPK-20-35 two-stage belt sway switch is a crucial safety device in conveyor systems, designed to monitor and control belt deviations. This advanced switch model effectively prevents damage to the conveyor belt and machinery by detecting abnormal positional shifts and automatically sending warning or shutdown signals.
**Product Overview**
The HRPK-20-35 is a high-performance, two-stage belt sway switch, featuring robust construction and reliable performance. Its primary function is to protect conveyor belts from damage due to deviation during operation. When the belt deviates beyond a certain angle, the switch promptly issues an alarm signal; if the deviation continues, it triggers a shutdown signal to stop the conveyor system, thereby avoiding potential hazards caused by prolonged belt misalignment.
**Key Features**
1. **Dual-Stage Angle Setting**:
- **First Stage Angle**: 20 degrees. When the belt deviates by more than 20 degrees, the switch sends out an initial warning signal.
- **Second Stage Angle**: 35 degrees. If the belt further deviates beyond 35 degrees, a critical shutdown signal is activated to halt the system immediately.
2. **High Reliability and Durability**:
- The switch boasts a mechanical life of over 100,000 cycles and features an automatic reset function. Once the issue causing the deviation is resolved, the system reverts to its normal operational state without manual intervention.
3. **Robust Construction**:
- Made from high-grade aluminum alloy, the HRPK-20-35 offers excellent resistance to dust, vibration, and corrosion. With a protection grade of IP65, it is well-suited for harsh industrial environments.
4. **Wide Temperature Range**:
- Operable within an environment temperature range of -30°C to +50°C, ensuring stable performance across varying climates.
**Installation and Application**
Installing the HRPK-20-35 is straightforward. It should be mounted perpendicular to the conveyor belt's longitudinal direction, with the roller axis aligned parallel to the belt edge. For optimal performance, it is recommended to place a switch pair every 30 meters along the conveyor line.
This switch is widely used in various industries such as mining, power generation, petrochemicals, metallurgy, food processing, and pharmaceuticals, among others. It ensures smooth operation and safety of conveyor systems, making it an indispensable component in modern industrial settings.
In conclusion, the HRPK-20-35 two-stage belt sway switch stands out for its reliability, durability, and ease of installation, providing superior protection for conveyor belt systems. Whether in challenging industrial environments or specific process lines, it offers effective monitoring and control, safeguarding equipment and personnel safety.
