As one of the main equipment for modern industrial material transportation, the safety and stability of belt conveyors are directly related to production efficiency and economic benefits. However, due to various reasons such as uneven material distribution, design defects of the conveyor itself or improper operation, belt conveyors often deviate during operation. This will not only affect the service life of the conveyor, but may also lead to serious consequences such as material spillage, equipment damage and even casualties. The two-stage deviation switch HKPP-12-30 is a professional equipment designed to solve this problem.

Working principle of the two-stage deviation switch HKPP-12-30

The two-stage deviation switch HKPP-12-30 is an automatic control sensor element specially used to detect the deviation phenomenon in the operation of belt conveyors. It uses the principle of combining mechanics and electricity to detect the relative position change between the belt edge and the vertical roller (or gear wheel) to determine whether the belt has deviated, and outputs the corresponding alarm or shutdown signal according to the degree of deviation.

Specifically, the two-stage deviation switch consists of two independent micro switches, corresponding to the first-level alarm and second-level shutdown functions. The two micro switches are triggered by the contact between the vertical roller and the edge of the belt. When the belt deviates slightly, the edge of the belt will press against the vertical roller on one side, forcing the vertical roller to deflect, thereby triggering the first-level micro switch to operate and output an alarm signal. If the belt deviation is not handled in time, when the deviation reaches a certain degree (such as exceeding the set secondary angle threshold), the secondary micro switch will be triggered, output a stop signal, and the conveyor will automatically stop to avoid more serious consequences.

It is worth noting that the sensitivity of the two-stage deviation switch can be adjusted according to actual needs. By adjusting the gap between the vertical roller and the edge of the belt, changing the trigger angle of the micro switch, etc., precise control of deviation detection can be achieved. This makes the two-stage deviation switch suitable for belt conveyors of different specifications and different operating conditions.

Applicable equipment for the two-stage deviation switch HKPP-12-30

The two-stage deviation switch HKPP-12-30 has been widely used in the field of industrial automation with its unique working principle and superior performance characteristics. Here are some common applicable equipment:

1. Conventional belt conveyor: This is the most basic application area of ​​the two-stage deviation switch. Whether it is horizontal conveying or inclined conveying, as long as the belt deviates, the two-stage deviation switch can promptly send out an alarm or stop signal to ensure the safe operation of the conveyor.

2. Underground and cableway-supported belt conveyor: In underground mines or cableway-supported systems, the deviation problem of belt conveyors is particularly prominent due to limited space and complex environment. The two-stage deviation switch can work stably in these special environments, providing strong guarantees for the safe operation of conveyors.

3. Ship loading and unloading system: In the ship loading and unloading system, belt conveyors are used to unload goods from ships to docks or warehouses. Due to the influence of natural factors such as waves and wind, belts are prone to deviation. The two-stage deviation switch can monitor the running status of the belt in real time to ensure the smooth progress of loading and unloading operations.

4. Stacking/reclaiming conveyor: In the field of warehousing and logistics, stacking/reclaiming conveyors are key equipment for automatic storage and retrieval of goods. Two-stage deviation switches can ensure that these conveyors always maintain a stable operating state during stacking or retrieving, improving operating efficiency and safety.

5. Inclined and shuttle conveyors: Inclined and shuttle conveyors are used to transport materials from one height to another or from one direction to another. Since the materials will generate a large impact force during the conveying process, the belt is prone to deviation. Two-stage deviation switches can monitor the operating state of the belt in real time to ensure the stable operation of the conveyor.

6. Crane and excavator boom limit: In heavy equipment such as cranes and excavators, the limit control of the boom is the key to ensure the safe operation of the equipment. The two-stage deviation switch can be used as a sensing element for the boom limit, monitoring the position change of the boom in real time, and preventing safety accidents caused by exceeding the limit range.

7. Skirt feeder/conveyor: Skirt feeder is a special conveyor used to evenly transport materials to the next process. Two-stage deviation switches can ensure that the skirt feeder always maintains a stable conveying state during operation, improving production efficiency.

When selecting a two-stage deviation switch, it is necessary to consider the specifications of the conveyor, conveying speed, material characteristics, etc., and then select the appropriate output method according to actual needs, and pay attention to the protection level of the switch to ensure that it can work stably for a long time.
