HKPP-12-30 two-level deviation switch cable support belt conveyor HKPP-12-30 two-level deviation switch cable support belt conveyor HKPP-12-30 two-level deviation switch purpose 1. There are 12mm holes on both sides of the two-level deviation switch base. Drill 12mm holes on the iron frame next to the belt conveyor and tighten the deviation switch with M10 × 30mm screws. 2. The installation of the deviation switch should be carried out at a location where the conveying device is prone to deviation, referring to the process requirements of the application unit. At the same time, the effective distance and thrust between the belt and the blocking wheel should be considered. It is recommended to install the distance between the belt and the blocking wheel between 120-160mm. 3. Installation distance: It is recommended to install a pair of deviation switches every 50 meters. 4. The deviation switch is equipped with a 0.5 meter long four core rubber sleeve cable when it leaves the factory. The core wires are equipped with wire numbers 1, 2, 3, and 4, where 1 and 2 are normally open contacts that are first level alarm signals, and 3 and 4 are normally closed contacts that are second level shutdown signals. Note 1: Keep the gear wheel of the deviation switch perpendicular to the belt. 2. It is recommended to maintain a distance of 120-160mm between the gear wheel of the deviation switch and the edge of the belt. 3. The base of the deviation switch is firmly fixed. Used to detect the deviation phenomenon during the operation of belt conveyors, and output alarm or shutdown signals based on the actual deviation amount of the belt, which can prevent accidents caused by belt deviation. It is a protective device that realizes automatic alarm and shutdown of the tape machine control. The two deviation switches are suitable for belt conveyors, which can send an alarm signal and further automatically stop the belt conveyor before serious edge wear or even tearing accidents occur due to belt deviation. Can timely protect equipment, avoid accidents from escalating, and achieve the goal of ensuring production and protecting equipment. In addition, as the signal can be sent to the control system, it is convenient to achieve factory automation control. The working principle of the HKPP12-30 deviation switch is that two deviation switches are installed on both sides of the belt conveyor, 1-3 meters away from the tail end of the belt conveyor. When the belt deviates, the edge of the belt presses against the gear wheel, forcing it to deflect and causing the limit switch to operate. To reduce friction between the gear wheel and the belt, the main body of the gear wheel is made of bearings. When a minor deviation accident occurs (12 °), the group contacts of the two deviation switches act and issue an accident warning signal. When a serious deviation accident occurs (30 °), the group contacts of the two deviation switches act, which can automatically stop the conveyor.
