In the process of using the scraper winch, due to long-term operation, it will cause various unexpected failures of the scraper winch. Generally, the scraper winch fails. We will immediately think of contacting the scraper winch manufacturer for repair. Sometimes the scraper winch is used. The location is far away from the scraper winch manufacturer. The technicians of the winch factory may not be able to rush to the winch site within 48 hours, which will affect us.
In the process of using the scraper winch, due to long-term operation, it will cause various unexpected failures of the scraper winch. Generally, the scraper winch fails. We will immediately think of contacting the scraper winch manufacturer for repair. Sometimes the winch is used. The location is far from the winch manufacturer. The technical personnel of the winch factory may not be able to rush to the winch use site within 48 hours. This will affect our production efficiency. In fact, sometimes small faults in the winch can be solved by ourselves. Let me talk about the cause of the leakage of the sealing part of the scraper winch and the repairing plan.
The reason for the leakage of the sealing part of the scraper winch is generally due to the loosening of the end cover bolts of the scraper winch for a long time. This can actually be easily prevented. During the use of any machinery, due to rotation, vibration, etc., Will cause the bolts to loosen. After the winch is finished running, we can check whether the bolts at all parts of the winch are loose, especially the anchor bolts. Loose anchor bolts can easily cause accidents in coal mining machinery. The solution to this bolt loosening problem is to lift the wrench. Tighten the bolts.
Leakage of the scraper winch seals. Second, the oil seal is damaged due to long-term vibration. We can replace it with a new oil seal in time.
Leakage Causes of Leakage Sealing Parts of Harrow Winches 3. Due to the long-term overload operation of the winches and the machine heating up, the seal parts of the scraper winches leak. The dispatching winch uses universal lithium-based grease (we also call it butter here). Lithium-based grease, especially lithium 12-hydroxystearate thickened grease, has only two intersection temperatures, the first intersection temperature (Ie, from pseudo-gel state to gel state) is generally above 170 ° C, and the second phase transition temperature (ie, from gel state to sol state) is generally above 200 ° C. Therefore, if the scraper winch is overloaded for a long time, The heat generated by the machine will cause the lithium-based grease to become a sol state, and the sol state can easily leak out of various gaps in the machine. Solution: Prohibit overload operation of the scraper winch!
