Explosion proof deviation switch DWPK12-30 Explosion proof deviation switch DWPK12-30 Explosion proof deviation switch DWPK12-30 Two stage deviation switch installation and adjustment: 1. The deviation switch is set on both sides of the conveyor belt, and the vertical roller should be perpendicular to the edge plane of the conveyor belt, and the two sides of the conveyor belt should be located at 1/3 of the height of the vertical roller. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be installed every 30-35 meters in the middle position of the conveyor.) DWPK-12-30 two-stage deviation switch features: rated value of switch contacts: 2 SPDTs (single pole double throw)< Switch, 16A/250V/AC two normally open and two normally closed self-cleaning contacts< Shell: Cast aluminum weather proof shell& nbsp;   Protection level: IP65< Normal alarm angle: 22.5 degrees away from the vertical direction; Adjustable< Force: 5 pounds DWPK-12-30 two-stage deviation switch Operating environment:
Environmental temperature: -40 ℃~+60 ℃; Relative humidity: not more than 90%< Atmospheric pressure: 80-110kpa; Altitude: not exceeding 2000M< Service life: 10000 switch actions; Insulation voltage: AC1000V test lasting for 1 minute. DWPK-12-30 two-stage deviation switch. Basic principle: When the conveyor belt deviates and comes into contact with the switch's vertical roller during operation, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation. After troubleshooting, when the tape leaves the vertical roller for normal operation, the vertical roller can automatically reset. DWPK-12-30 two-stage deviation switch installation and adjustment: 1. The deviation switch is set on both sides of the conveyor belt, and the vertical rollers should be perpendicular to the edge plane of the conveyor belt, and the two sides of the conveyor belt should be located at 1/3 of the height of the vertical rollers. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be set every 30-35 meters in the middle of the conveyor); Mainly for the purpose of chain protection. A common example of Zui is its application in washing machines and recording machines (video recorders). During the dehydration (spin drying) process of the washing machine, the rotational speed is very high. If someone accidentally opens the door or cover of the washing machine and then extends their hand in, it is easy to cause harm to people. To avoid this accident, an electric contact point is installed on the door or cover of the washing machine. Once someone opens the door or cover of the washing machine, the motor will automatically shut off, and even mechanical means will be used to link it, so that the door or cover will open immediately; Brakes;, Force the rotating parts to stop to avoid personal injury. In audio and video recorders, we often use fast forward or rewind, where the tape rotates rapidly but automatically stops when it reaches its endpoint. Here, the travel switch once again played a role, but this time it was not caused by collision, but by the sudden increase in tension on the magnetic tape.
