Causes of leakage in the winch sealing part and maintenance methods
Release time:

During the use of the winch, due to long-term operation, the winch can cause various unexpected failures. Usually, the winch will be damaged. We will first consider the contact information for the manufacturer's maintenance scheduling for the winch. Sometimes, the distance from the winch to the manufacturer is very far, and the technicians from the pneumatic winch factory may not be able to reach the winch site within 48 hours, which can affect our work efficiency. In fact, sometimes the winch failures can be resolved by ourselves. Let me talk about the causes of leaks in the sealing parts of the pneumatic winch and the maintenance methods.

WinchCauses of leakage in the sealing part:
1. This is usually caused by the long-term loosening of the end cover bolts of the pneumatic winch, which is actually easy to prevent. Any mechanical use during this process may cause the bolts to loosen due to rotation, vibration, etc. After the winch operates, you can check whether the bolts in the winch are loose, especially the anchor bolts. Loose anchor bolts can easily lead to safety accidents in our coal mine machinery. To solve the problem of loose bolt connections, please tighten the bolts.
2.WinchThe oil seal can be damaged due to long-term vibration. We can replace the new oil seal in time to solve these problems.
3. Due to the long-term overload operation of the winch and the heating of the machine, the sealing part of the winch will leak. Lithium-based grease is usually used in pneumatic winches, especially in lubricants thickened with 12-hydroxystearic acid, which has only two crossover temperatures.
1) Crossover temperature (i.e., from gel state to gel state), usually above 170°C.
2) Phase change temperature (i.e., from gel state to sol state) is usually above 200°C. Therefore, if the pneumatic winch is overloaded for a long time, the machine will heat up, causing the lithium-based grease to change to In. In the sol state, the sol state can easily change due to leakage in various gaps of the machine.WinchSolution: Do not overload!
