When the coal mining scraper conveyor is stopped for various reasons during operation, it will be in a heavy-load start state when it is restarted, which is different from the initial start. In order to enter the running state, the various parts of the equipment must meet the corresponding requirements.
The first is the requirement for the inverter of the coal mining scraper conveyor to ensure that it can start the conveyor with heavy load on the coal mining scraper conveyor; the second is the requirement for the motor of the coal mining scraper conveyor. The torque output by the motor not only needs to overcome the roller and roller shaft The resistance torque caused by the static friction between the two must also overcome the resistance torque caused by the downward pull of the material on the coal conveyor.
This draws a conclusion that the inverter equipped with the coal mining scraper conveyor must have the function of low speed and large starting torque. Moreover, this large low-speed starting torque needs to be maintained for a certain period of time, mainly due to factors such as the low speed at starting and the elasticity of the belt.
