Coal mining scraper conveyor can be divided into heavy-duty belt conveyors, such as mining stainless steel roller conveyors, and lightweight coal mining scraper conveyor used in the food light industry, chemical medicine and other industries. The coal mining scraper conveyor is instructed to operate the material control system, but the scraper conveyor control system also has certain requirements. If the motor next to the coal mining scraper conveyor is directly overloaded and started, the power supply needs to provide six to seven times more current than during normal operation.
Due to the excessive current of the coal mining scraper conveyor and the long startup time, the motor will be burned. When the current is too large, the voltage is fast, the rollers and the tape slip, which causes conflicts, causing the belt to wear quickly and affect the belt's service life. Therefore, under the heavy load of the coal mining scraper conveyor, the torque can be started at low speed, stable, and the dynamic stress can be reduced without charging. Scraper conveyor, if the starting acceleration is too large, it will cause the material to drop. When the scraper conveyor is used in combination, the front is equipped with a loader, and the rear is equipped with a discharger or a conveyor.
Or the capacity of the coal mining scraper conveyor is too large. When a heavy load occurs, the motor will be burned. This requires speed control. When the load is high, the material can run quickly. When you are young you may want to run at low speed to complete a full load. During the operation of the scraper conveyor, many obstacles such as configuration obstacles, safety and material particles should be monitored.
Coal mining scraper conveyor usually consists of driving roller set, roller set, tensioning device, cleaner, conveyor belt, guide groove, various protection devices and key components such as head, tailstock and middle frame. The driving device of the coal mining scraper conveyor is mainly divided into a mechanical driving device and a hydraulic driving device. Mechanical drives are used to ensure the safety and reliability of the system. As a result, designs often follow system full-load startup and long-term operating conditions.
