Elevator wire rope, as the name implies, is the wire rope used in elevators. It is the most used small passenger elevator. In commercial residential districts, elevator wire rope specifications are generally 8*19S+FC-8mm, 8*19S+FC-10mm.
Under normal circumstances, most of the new factory wire ropes have been lubricated during production, but during use, the loss of lubricating grease will be reduced. In view of the fact that lubrication can not only play a role in the corrosion protection of the steel wire rope during transportation and storage, but also can reduce the wear between the steel wires, between the rope strands and between the steel wire rope and the traction sheave groove during the use of the wire rope, and is used for the extension of the wire rope. Longevity is also very beneficial. Therefore, in order to minimize the damage of corrosion and wear to the steel wire rope, it is necessary to conduct a lubrication inspection. First of all, we must choose a suitable wire rope grease. The elevator wire rope grease should be a special friction grease with a certain friction coefficient. High-performance wire rope grease is the fundamental guarantee for maintaining the wire rope and extending the life of the wire rope. When the steel wire rope is working, there is three-dimensional fretting friction inside, which requires that the steel wire rope grease must have strong penetrating properties, that is, the lubricant molecule and antiwear agent components in the grease can penetrate each steel wire. In addition, the steel wire rope grease must also have strong adhesion properties. To ensure its uniform adhesion to each steel wire rope. There are usually several methods for the lubrication and maintenance of the wire rope. One is to disassemble the wire rope and soak it in lubricating oil with a temperature of 80 to 100 degrees for about 2 to 4 hours. The other is to directly apply the lubricant to the wire rope with a brush. Above, the key is to master the brushing method and interval. Generally speaking, for a wire rope with a diameter of about 12mm, about 1kg of lubricating grease is applied every forty meters, and the interval is about two weeks; the other is to use The special steel wire rope lubrication equipment lubricates the steel wire rope, this method is the most trouble-free, but the equipment cost is higher. The specific lubricant and lubrication method should be carried out in accordance with the requirements of the wire rope manufacturer. At present, not many elevator maintenance units really pay attention to the lubrication and maintenance of steel wire ropes. Many units have become accustomed to replacing new steel wire ropes without paying attention to lubrication management. This is only one aspect of the requirements to ensure the safe use of wire ropes. In addition, it is necessary to check the peripheral conditions of the wire rope use, such as the surface wear of the traction sheave groove, and the geometry of the wheel groove to ensure that the wire rope is always in good contact during operation to reduce friction. Ensure the safe operation of the elevator.
