NST2-II Bidirectional Rope Switch Shandong Zhuoxin Machinery Co., Ltd. is located in Shandong, a major economic province in China. It mainly engages in the production and sales of instruments, automation equipment, and complete supporting products. Its main products are sold to factories, mines, power plants, and universities across the country. Our products include non-destructive testing equipment, ultrasonic thickness gauges, coating thickness gauges, vibration gauges, noise gauges, infrared thermometers, pressure gauges, pressure controllers, oscilloscopes, power supplies, bimetallic thermometers, thermocouples, thermistors, temperature transmitters, proximity switches, rope switches, deviation switches, push-pull force gauges, testing machines, and other supporting products< The NST2-II bidirectional rope switch is widely used in factories and mines with belt conveyors, such as steel, cement plants, and power plants. The product is installed on both sides of the belt conveyor and is a protective switch for emergency accidents of the belt conveyor. It pulls the steel wire rope at any point within the operating distance of the switch, cuts off the running circuit, and stops the entire line to achieve protection for the belt conveyor and personal safety. It is divided into S-type and Z-type. After the S-type action, it self sells and needs to be manually reset. Z-type automatic reset, when an emergency occurs, the machine can be stopped by pulling the rope sensing gas at will. Parameters: Voltage: 380V, current [optional] 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A. The rope switch is divided into manual reset and automatic reset, and needs to meet the national IP level. Automatic reset: After the action, it can automatically return to the initial position, which may cause errors in startup. Manual reset: After the action, there is a self-locking device that can be kept in the operating position. It is necessary to manually operate the reset handle to return it to the initial position. The pull rope switch is a safety protection device for belt conveyors, preventing the expansion of accidents and causing significant losses. Due to its convenient installation and reliable switch conversion, it has been widely used in belt transportation sites. The installation and adjustment of rope switches should be installed in places with maintenance channels on both sides of the conveyor, and the installation position should ensure that maintenance personnel can operate conveniently in emergency situations. 1. Fix the rope switch on the rack. 2. The distance between the two switches on one side is about 50m, using a diameter ofΦ The steel wire rope connection of 4 should have moderate elasticity. 3. To reduce the impact of the weight of the steel wire rope on the start of the switch, a support ring is installed on the frame every 3 meters to support the steel wire rope. 4. The other end of the steel wire rope is tied to the tension spring (fixed with a rope buckle), and the tension on both sides of the rope is tightened using a tightener without affecting normal use, ensuring that the tension on both sides is balanced. (Note: For the climbing section conveyor, the switch spacing and rope length should be minimized as much as possible.) Working principle: In case of an emergency on site of the belt conveyor, the steel wire rope tied to the hanging ear is pulled at any position along the line, forcing the cam inside the machine to rotate and driving the component switch to act, issuing a shutdown signal to achieve the shutdown effect and prevent the expansion of the accident. Environmental conditions for use:
a. Environmental temperature: -40 ℃~60 ℃
b. Relative humidity not exceeding 85%
c. Sea level not exceeding 2000m
d. Service life: 100000 switch actions
e. Insulation voltage: AC1000 test for 1 minute< The NTSG-II bidirectional rope switch is a switch device used to control the start and stop of equipment. It adopts a bidirectional rope pulling method, and when one side of the rope is pulled, the other side of the rope will also be pulled, thereby achieving the start stop control of the equipment. This switch has the following characteristics: bidirectional rope pulling: The NTSG-II bidirectional rope pulling switch can control two devices simultaneously, and the equipment can be started and stopped by pulling the ropes on both sides. High reliability: The switch is made of high-quality materials, which have good durability and corrosion resistance, and can work stably for a long time in harsh working environments. Easy to install: The switch is compact, lightweight, and easy to install and maintain. Multiple wiring methods: The NTSG-II bidirectional rope switch supports multiple wiring methods, including single pole double throw, single pole single throw, etc., which can be selected according to actual needs. In summary, the NTSG-II bidirectional drawstring switch is a reliable and efficient switching device widely used in various industrial automation control systems< br/>
