The Medium speed coal mill pull rod loading device seal 22MG40.11.14 can effectively prevent the leakage of sealing air and oil inside the coal mill. During the operation of the coal mill, the rod needs to rotate along its own axis, accompanied by its own axial and radial displacement. The seal prevents the leakage of sealing air and oil by tightly fitting the gap between the rod and the casing, ensuring the sealing inside the coal mill. Good sealing performance helps to improve the stability and reliability of the coal mill. The seal can reduce equipment failures caused by air leakage, oil leakage or impurities entering, and extend the service life of the equipment. For example, the improved sealing device can ensure the long-term, safe and effective operation of the coal mill, and the replacement cycle of wearing parts can be extended to the overhaul period of the coal mill. |
