When the screw conveyor is conveying materials, its common structure is to choose the motor + slower + middle section to choose the structure mode of hanging bearing, which is about the screw conveyor with long conveying interval. The screw conveyor used in agriculture is a light-loaded structure. Its spiral blades are mostly made of flat steel strips. Perhaps the drawn spiral blades are installed in the continuous spiral groove of the spiral tube shaft by means of rolling. This screw conveyor is only used in an equally short period of time, about 4-6 weeks a year. Its working load is only 15-30% of full load, but its running speed is very high. Industrial screw conveyors are required to operate at full load and low speed, and the spacing between the suspension supports is large, and the suspension supports can be removed in order to increase the conveying strength of the screw conveyor and reduce the amount of maintenance. Our goal is to increase the conveying efficiency of the screw conveyor, so we must understand the factors that affect the conveying efficiency of the screw conveyor: such as the size of the conveying volume, the size of the diameter, the inclination, and the conveying interval and speed.

The speed of the screw conveyor touches the power of the conveying mechanical engineering machine. The working speed of the screw conveyor is closely related to the characteristics of the material. The manufacturing requirements of the high-speed screw conveyor are strict and the average is better. At the same time, the size of the motor power determines the size of the conveying capacity of the screw conveyor. If the power of the selected motor is too small, the running speed of the material in the tube or tank will be too slow, which will greatly affect the conveying efficiency, and it is still possible that the motor will be destroyed due to the excessive load. On the contrary, if the motor power of the conveyor equipment is too large, it will increase the power consumption and increase the manufacturing cost of the enterprise.

The diameter of the spiral pipe of the screw conveyor affects the conveying efficiency. Under the same conditions, the conveyor with a larger pipe diameter has a higher conveying efficiency than a smaller pipe, and its conveying capacity and conveying efficiency are both higher. In addition, the inclination angle and interval of the screw conveyor also have a positive effect on it. The pipe diameter of the screw conveyor also determines the size of the conveying capacity, and for the trough screw conveyor, it is the width of the conveying trough. The key to choosing a large-diameter pipe and long-interval screw conveyor is to use a super-large-diameter pipe shaft, which can not only increase the changing strength of the pipe shaft, but also greatly reduce the bending deflection of the pipe shaft, which helps to reduce The number of hanging supports may not be used for hanging supports, thereby reducing manufacturing costs.
