The storage of the ring chain is also helpful to extend the service life of the chain. When the parts of the equipment are not in use, they must be carefully stored and cannot be thrown casually, so as to avoid rust or other damage to the chain.
When storing, pay attention to the storage environment, can not be placed in a humid place, the temperature should not be too high, and chemical corrosion of the place is prohibited.
Because if the temperature is too high, or by the direct sunlight, these mining chains, such as the commonly used dregs chain surface temperature will also increase, so that the physical properties of the chain will change, be damaged, affect the use!
After sprocket wear is serious, should replace new sprocket and new chain at the same time, in order to ensure good meshing.
New chains or sprockets cannot be replaced alone.
Otherwise, it will cause bad meshing to accelerate the wear of new chains or sprockets.
Sprocket tooth surface wear to a certain extent should be turned over in time to extend the use time.
When it comes to mining chains, the first reaction for everyone is that the chain is very thick and especially heavy, because the thicker the chain, the more powerful it is to lift things, and the larger the tonnage is, in fact, there are many kinds of lifting chains.
Mine chain products reach the specified performance indicators (such as life, minimum tensile strength, wear resistance characteristics, etc.), even the completion of the specified functions.
Otherwise, the chain product is said to lose the specified function.
The loss of the specified function of the product is generally referred to as the "failure" of the product, and the repairable product is often referred to as the "failure".
The key difference between mine chains and other chains lies in the strong coefficient, the use of forged vertical rings and special heat treatment, the high tensile strength of domestic chains with long fatigue life and high toughness, because of its special service environment, casting it does not use the processing technology.
For the maintenance of mine chain link rings, we need to be comprehensive.
Smearing method is widely popular, easy to operate, waste oil can be seen everywhere, it is advisable to wait.
Most users often and consistently adopt it.
Disadvantages: First, the oil has strong fluidity and little effect on the internal lubrication of the chain, and the high-strength mining chain is gradually thrown out after high-speed movement, which is easy to dirty the rear wheel of the car and requires frequent refueling.
The butter heating method, using butter as the main material, supplemented by oil (or molybdenum disulfide, paraffin, etc.), is filled in a metal container and heated together with the chain, so that the solid liquefied fluid enters the friction surface of the winding drive.
The advantage of this method is that the lubrication is more thorough, compared with the oil, butter adhesion strong, not easy to throw out, long maintenance cycle.
Under the condition of maintaining high strength, mining chains can effectively prevent the stress corrosion fracture of chains in underground coal mines. It does not reduce the resistance to stress corrosion due to wear, but it does not have obvious anti-rust effect on the surface of chains.
