What kind of frame seal is used for the drum cutter reducer ?

Fluctuation tightness, the cutting depth of each cutter of the vertical milling machine under the mine is 0.5m, and the cutting depth of 1.6-3.0 is the most suitable for a circulation system, but it does not exceed 3.6 meters. How to express a circulation system? It is the amount of water inflow once cut, which is called circulation system work, and the foundation pit support of 1.6-3.0 meters is cut once.

The development trend of vertical drum cutter in China has been in recent years. With the rapid development of China's coal industry, the field of coal mining machinery that stands shoulder to shoulder has also been paid more and more attention.

In the programmatic document of the coal industry "Several Opinions on Promoting the Healthy Development of the Coal Industry", in the Coal Industry Science and Technology Progress Conference and the current policies on the adjustment of the coal industry industrial structure issued by the regional development and reform commissions, all involve the development of large and medium-sized coal mines Comprehensive coal mining equipment and other specific content.

Tunneling and mining face are the key production processes of coal mine manufacturing. Our country's policy is: to develop simultaneously, and to give priority to tunneling.

The rapid excavation of coal mine roadway is the core technical countermeasure of coal mine to ensure high and stable production of coal mine. Mining technology and equipment level are related to the ability and safety of mine production. High-efficiency mechanical automation excavation and foundation pit support technology are the necessary conditions to ensure the high efficiency of coal mine production increase, and both are the development direction of roadway excavation technology.   With the technological development of coal mining teams, there have been special working tables with an annual output of several million tons, or even tens of millions of tons, which has greatly increased the number of roadways in the mining face, making roadway excavation a highly efficient and intensive coal mine. The relevance and crucial technicality of modernized production.

What is the main reason for the overheating of the drum cutter  200?

Just check if it's a problem with the circuit, if it is not a problem with the circuit, see if there is a problem with the heat dissipation.

After the crawler horizontal drum cutter is started, the reducer motor automatically trips when the coal has been cut, what happened, and everything else is normal.

The oil quantity, temperature, and the grounding device of the motor of the reducer still need to find the reason from the circuit schematic diagram. There are as many reasons as there are maintenance auxiliary circuits. Check them out one by one.
