The selection of the coal mining scraper conveyor should not only follow the general principles of the selection of conveying equipment, but also consider the following points: According to the arrangement of the process flow, the model of the coal mining scraper conveyor should be selected reasonably. For example, grain depots, grain depots, and feed processing plants generally use MS coal mining scraper conveyor to transport raw grains, finished products, and semi-finished products. In the production process of oil plants, MC coal mining scraper conveyor and MZ coal mining scraper conveyor can be used to transport oil. According to the conveyor type and material type, determine the appropriate type of scraper chain. Roller chains are not suitable for conveying powdery materials.
However, sometimes the overcurrent protection in the coal mining scraper conveyor cannot effectively protect the equipment, especially when the equipment fails. It can be seen that adding a motor overcurrent protector cannot completely protect the coal mining scraper conveyor, and it has greater limitations.
The speed regulating motor of the coal mining scraper conveyor is a motor that changes the speed of the motor by changing the number of stages, voltage, current, and frequency of the motor. So that the motor can achieve higher application functions. The general motors of the coal mining scraper conveyor include variable frequency load motors, fans and pumps with UVW wiring integral motors. The manufacturing process of this motor is not complicated, and its advantages are low price and strong applicability, but the disadvantage is that the starting energy torque and torque are small.
Since most of the current machinery and equipment are electric, they are equipped with overcurrent protection devices, and the coal mining scraper conveyor is no exception. Reasonable overcurrent protection can prevent equipment damage due to overcurrent and protect the normal operation of the coal mining scraper conveyor.
The coal mining scraper conveyor consists of a screw shaft with spiral blades, a barrel and a bearing device. Considering the importance of its tightness, the seal between the screw shaft and the bearing adopts a double oil seal. The oil seal can prevent fine powder from entering the bearing housing, and the right seal can prevent bearing grease from flowing into the cylinder.
