Elevator wire rope, that is, the wire rope used in the elevator. Among them, the most used small manned elevators, commercial residential areas, we talk about elevator wire ropes, elevator wire ropes are mainly divided into traction wire ropes and speed limiter wire ropes, elevator traction wire ropes generally use 8*19S-FC- 8mm8*19S-10mm and the mall uses a slightly larger elevator wire rope 12mm13mm mall cargo elevator, 12mm13mm16mm diameter elevator wire rope, and the speed limiter wire rope diameter is generally 6mm or more and 8mm or less.
Most of the new factory wire ropes have been lubricated at the time of production, and the working principle of the elevator wire rope is usually under normal circumstances. However, during use, the grease will be lost. In view of the fact that the lubrication can not only protect the wire rope during the transportation and storage, but also reduce the wear between the wires during the use of the wire rope, between the strands and between the wire rope and the traction sheave, and the use of the extended wire rope Life is also very beneficial.
Therefore, in order to minimize the damage caused by erosion and abrasion on the wire rope, it is necessary to carry out lubrication inspection. First of all, we must choose the appropriate wire rope grease, elevator wire rope grease should use a special friction grease with a certain coefficient of friction, high-performance wire rope grease is the fundamental guarantee for maintaining the life of wire rope extension wire rope. When the wire rope is in operation, the inside presents three-dimensional fretting friction, which requires that the wire rope grease must have a strong permeation function, that is, the lubricant molecule anti-wear component in the grease can penetrate and permeate to each wire. Above, elevator wire rope specifications.
In addition, the elevator wire rope grease must also have a strong adhesion function to ensure its average adhesion to each wire rope. There are usually several ways to lubricate the wire rope. One is to remove the wire rope and put it into the lubricating oil at a temperature of 80100 degrees for about 24 hours. The other is to brush the lubricant directly on the wire rope. The hub is The method and distance of painting should be well grasped. Generally speaking, the wire rope with a diameter of about 12mm is about 1 kilogram of grease for every forty meters, and the brushing distance is about two weeks. The other is to use special wire rope lubrication equipment. Lubricate the wire rope, this method is the most trouble-free, but the interest on the equipment is higher.
Which lubricant and lubrication method should be used in detail should be carried out in accordance with the requirements of the wire rope manufacturer. At present, elevator maintenance units really face up to the lubrication of steel wire ropes. Many units have become accustomed to replacing new steel wire ropes without paying attention to lubrication treatment. This is only one aspect of ensuring the safe use of wire ropes. In addition, it is necessary to check the external premise of the wire rope, such as the appearance of the traction wheel groove and the geometry of the wheel groove, so as to ensure that the wire rope is always in good contact state during operation to reduce the friction. Ensure that the elevator runs safely.
The detailed introduction of the elevator wire rope is mentioned here. We work on the maintenance of the elevator wire rope every day. Other knowledge about the elevator wire rope has to be explored by the staff themselves.
