The use of wire rope in maintenance is very important, do the work, not only can prolong the service life, but also can improve the work efficiency, prevent the happening of the accident. Maintenance in the use process, is mainly refers to the steel wire rope lubrication and anti rust oil etc..
A: the wire rope lubrication
The steel wire rope in the manufacture has been coated with enough oil, but after running, the oil will be gradually reduced, and the steel wire rope surface dust, debris and dirt will occupy, cause the wire rope and sheave rope wear and rust, therefore, should be regularly cleaned and gas. A simple method is use wire brush dirt and other appropriate tool to erase the dust from the surface of steel wire rope, the wire rope grease melt when heated evenly coated on the surface of steel wire rope.
In the production process, we will for the lubrication of the steel wire rope, the wire stock and the stock can be moved along with the steel wire rope and bending and automatic adjustment. However, the lubrication process can not guarantee sufficient lubrication in the whole life cycle of the steel wire rope. Therefore, the service life of the wire rope in regular lubrication is critical.
In the process of operation, the surface covered with mud, a stone or other material. This will prevent the lubricating oil field is applied into the steel wire rope, therefore, it is necessary to clean the steel wire rope in the lubrication before.
The lubricating oil should be low consistency, so as to penetrate to the core. There are three kinds of lubrication: trickle down, spray, brush type. Either way, should be in the bend of the steel wire rope, such as slot wheel, lubrication. We recommend that you at the bend at the top of the use of lubricating oil, because this position because of bending and stretching the rope strands, and easier to penetrate. In addition, in the business can be pressurized lubrication way. Effective lubrication service life of wire rope with you by and directly related to the amount of lubrication.
Proper lubrication can reduce friction, corrosion prevention must be adhered to, and the steel wire. At the same time must be flexible, no crack or crack, cold heat without dropping. Do not use too much grease for wire rope, because the hard so that the wire rope and the friction and adhesion, damage of steel wire rope. Also avoid using machine used lubricating oils, because it contains the damage of wire rope material. If special circumstances, you can provide us with special in the production of lubricating oil.
Two: the daily inspection
Because the steel wire rope is not only bear the load, fatigue, wear, and poor working environment, the use of daily maintenance and inspection is very important. The main content of the maintenance of maintenance and inspection as follows:
1, regularly for wire coating with anti rust and lubrication oil.
2, regularly remove dirt surfaces of steel wire rope with dust and other impurities.
3, daily check and record the steel wire rope wear, broken wires, rust, grease, deformation, diameter and other abnormal conditions.
4, the wire rope should be checked before use. When the wire rope wear, broken, broken strands, tensile, bending, deformation, corrosion, fatigue, diameter, the rope core exposed to replace the standard degree of relevant rules, the timely replacement of the new rope.
Matters needing attention: three:
Have a great relationship with the use of wire rope for use, and therefore should be required to use, do not drag, throwing, use no overload, are not allowed to make wire rope angle bending, no sharp change of lifting speed, avoid the impact load;
Steel wire rope with rust and dust, use wire brush to | and oil;
Wire rope oiling every 4 months at a time, preferably with hot oil (50 DEG C) when soaked rope core, and then wipe the excess oil;
After the wire rope wheel should be placed in a clean dry place, not overlapping stacking, prevent sprains;
At the end of the wire rope with steel truss with low melting point alloy or welded, can also be used to prevent the iron hoop, rope loose;
The use of wire rope surface, such as a drop of oil out of the wire rope, said has been subjected to considerable strength, you should stop load increase, and check, replace the new rope when necessary.
