What problems should be paid attention to in the process of purchasing sprocket shaft group:
With the development of coal mining machinery and the consolidation and merger of small and medium-sized coal mines by the state, large-scale fully mechanized mining equipment is more and more widely used in coal mines. For scraper conveyors, in order to constantly adapt to the increase of transportation volume, their scale is gradually developing to large and heavy scraper conveyors, and at the same time, there are more and more types of scraper conveyors, and the models produced by major coal machine manufacturers are also different. As the main vulnerable parts of scraper conveyor, sprocket shaft group is not universal and difficult to determine when purchasing, so it should be determined when purchasing sprocket shaft group. We have summarized the following aspects.
First, the main engine manufacturers of sprocket shaft groups. Because there are many manufacturers of scraper conveyor, it is impossible for each manufacturer's sprocket shaft group to be universal, so when purchasing, we must first determine which manufacturer's scraper conveyor is suitable for sprocket shaft group. At present, the most important scraper conveyor manufacturers in China mainly include China Coal Zhangjiakou Coal Machine Factory, Ningxia Tiandi Coal Machine Factory, Shandong Coal Machine Factory, Shanxi Coal Machine Factory and Zheng Coal Machine Factory.
Secondly, the determination of the drawing number of sprocket shaft group. Even for the scraper conveyors of the same manufacturer, the sprocket shaft groups suitable for the same type of scraper conveyor are not necessarily the same. Therefore, it is necessary to determine the drawing number of the sprocket shaft group, and each sprocket shaft group has only one set of drawings. As long as we find the drawing number of the sprocket shaft group and have the corresponding drawings, we can ensure that the produced sprocket shaft group will not have problems.
Thirdly, the material selection of sprocket shaft group. Due to the increasing power and transportation volume of scraper conveyor, there are great requirements for the toughness and strength of sprocket shaft group. If the materials are not selected properly, the sprocket shaft group is prone to accidents during use, which will affect the production progress and even lead to safety accidents. At present, the commonly used materials are 42CrMo and 45CrNiMnMu, and the appropriate materials should be selected according to the traffic volume.
Fourthly, the manufacturing technology of sprocket shaft group. Because of the high toughness and strength requirements of sprocket shaft group, the manufacturing process should not be sloppy. At present, the manufacturing processes of sprocket shaft group mainly include forging, casting and welding. Small general scraper conveyor can choose casting and welding sprocket shaft group. For large-scale fully mechanized sprocket shaft group, in order to ensure its performance requirements, only forged sprocket shaft group can be selected, and it can be heat-treated and tempered.
Pay attention to the selection of the above aspects when buying sprocket shaft groups. Basically, this kind of sprocket shaft group can basically meet the performance required by the current scraper conveyor, but there is still one thing to pay attention to, that is, when the scraper conveyor is running, we must always pay attention to the wear of sprocket shaft group to avoid accidents.

The above are the problems that should be paid attention to in the process of purchasing sprocket shaft group and the price introduction of sprocket shaft group manufacturers. Here, Bian Xiao reminds everyone once again that you must be very cautious when buying sprocket shaft sets, and make a decision after knowing all the information. You should not be greedy for petty gain when buying. Buying high-quality products is king. At the same time, when using the sprocket shaft group, it is necessary to regularly check the wear of the sprocket shaft group and take preventive measures to avoid accidents. I hope the above content can help you!
