Coal mining scraper conveyor is a continuous transportation equipment for conveying bulk materials by means of a moving scraper chain. It is widely used in metallurgy, building materials, electric power, chemical industry, cement, ports, docks, coal, mining, grain and oil, food, feed, etc Industry and sector. However, because the coal mining scraper conveyor is often started at full load, it is particularly difficult to start, but in fact, a high-quality fluid coupling can solve this problem.

The main characteristics of the coal mining scraper conveyor are frequent starting and full-load and heavy-load starting. The load is constantly changing and irregular between no-load, full-load, overload, and even severe overload. In order to solve the start-up difficulty and protect the overload problem, the coal mining scraper conveyor is almost all driven by a torque-limiting hydraulic coupling.

The moment fluid coupling can use the peak torque of the motor as the starting torque to avoid the unreasonable matching phenomenon of the "big horse-drawn trolley". At the same time, it shortens the electric starting time and reduces the starting current during starting. The most important thing is to prevent power overload, protect the motor and working machine from damage due to overload, and reduce vibration and shock during starting. And in the multi-motor drive, the motors can be started separately, power balance can be performed, and the rated torque that limits the starting torque of 1.2 to 1.6 times can be provided as the starting torque, which better improves the operating efficiency of the coal mining scraper conveyor.
