The improvement of mining production efficiency requires the support of various mechanical equipment. Therefore, the use of mine car equipment provides support and assistance for mining production. How to improve the sealing of the mine wheel pair in the structure of the mining cart?
The sealing groove on the narrow gauge mine car wheel and the inner cover form a labyrinth seal, and the felt embedded in the sealing groove forms a contact felt ring seal. Because the labyrinth seal is very short, it cannot effectively prevent water intrusion and grease leakage. At the same time, wool felt is easy to compress and wear, and coal powder is easy to infiltrate, which intensifies the wear of mine car wheels.
The improved narrow gauge mine car wheel uses M-shaped seals. The M-shaped seal is a combined seal with two lip seals and two grease seals. A spring is installed inside the main lip, which can not only increase the sealing pressure, but also maintain tight contact with the journal, and can It automatically compensates for the gap caused by lip wear and plays a "self-tightening effect".
The main and auxiliary lips of the mining cart wheel are turned outwards, which can effectively prevent the intrusion of water and slime, and has excellent dustproof and waterproof capabilities. In addition, the surface of the journal matched with the sealing surface of the M-shaped sealing ring is hardened, which reduces the wear of the sealing ring and improves the service life of the sealing ring.
According to the brief overview of the above editor, we will improve the sealing of the mine wheel pair and provide support and help to improve the operation efficiency of the mining cart. If you want to understand the knowledge of other aspects of the mine car, you are welcome to call for consultation.
