Wuhan Junwei JW-PP series two-stage deviation switches are specially developed for belt conveyor systems. They are used to monitor the operating status of the continuous conveyor in real time. When the belt deviates from the designed running trajectory, alarms and stop signals can be triggered in stages to stop the upstream conveying system in time to avoid material leakage, belt tearing, equipment damage and other faults.
The product meets the special requirements of industrial safety regulations. It adopts a two-level action trigger design, a first-level alarm and a second-level shutdown. It is suitable for fixed installation and mobile transportation equipment. It has a high level of protection and can be used in harsh industrial environments such as mines, ports, steel, building materials, etc. Long-term stable operation is the core protective device to ensure the safety of conveyor equipment and operators.
The product adopts cast aluminum shell + fully sealed waterproof design, built-in high-quality microswitch, and the action angle supports on-site customization and reset. It is convenient to install and simple to operate and maintain. It can be seamlessly connected with the conveyor control system to achieve fully automatic safety protection.
Two-level hierarchical triggering
Automatic reset design
High protection and long life
Adjustable action angle
Product core structure
With a two-stage action design, when the belt deviates and the vertical roller deflects by 20°, the first group of microswitches triggers an alarm signal; when the deflection angle exceeds 35°, the second group of switches triggers a shutdown signal, and the action angle supports factory customization or on-site reset adjustment., which not only ensures equipment early warning redundancy, but also accurately achieves fault shutdown protection.
Equipped with 60mm diameter detection vertical rollers, it can be adapted to the operating conditions of high belt speed conveyors; the maximum deflection angle of the vertical rollers can reach 75°, which is suitable for belt conveyors with various bandwidths and groove angles. It can be installed on both sides of the belt. It can be adapted to fixed installation and mobile conveying equipment, with flexible installation methods and wide application scenarios.
The product adopts cast aluminum shell + fully sealed waterproof structure, with a protection level of IP67. It can operate stably for a long time in a wide temperature environment of-20℃~+60℃, harsh industrial scenarios such as high dust, humidity and corrosion. It has built-in high-quality micro switch, long mechanical life, stable and reliable action, and long trouble-free operation cycle.
The torsion spring automatic reset design is adopted. When the belt deviation fault is eliminated and returns to the center position, the deviation switch can be automatically reset. No manual operation is needed, and the conveying system can be restarted directly; the built-in wiring indication terminal makes wiring convenient, and it is equipped with a special cable Gran head to ensure the sealing and protection effect at the wiring point.
Level 1 alarm Level 2 shutdown
IP67 protection against harsh working conditions
Fault elimination and automatic homing
Clear wiring ready to be installed and used
