Elevator Steel Wire Rope Wear Resistant For A Long Time
Elevator rope structure is mainly 8 * 19S + NF of the Xilu type structure used as a traction rope, the choice of Xilu type is the advantage of thicker outer wire, wire rope in the process of frequent lifting and traction wheel contact, wear resistance; Second, the outer wire more than 450 # excellent line drawn into the rope, the nominal tensile strength of 1370MPa, reducing the strength of the outer wire is to prevent damage to the traction wheel; inner wire 1770MPa, to improve the wire rope breaking force ; For example: 8 * 19S + NF-13mm Xilu type wire rope cross section of the cross-section of 1 +9 +9 per share, that is, the first layer of the core plus the second layer of a total of 19 steel wire composition: the central wire 1, ф1. 2mm, the inner wire 9, ф0.6mm, outer wire 9 ф1.05mm. Outer wire diameter than the inner diameter of the wire, so also known as the outer rough wire rope.
Elevator wire rope, which is used in the elevator wire rope. Which is the largest use of small manned elevator, commercial residential area, we talk about the elevator wire rope, elevator wire rope generally used 8 * 19S-FC-8mm8 * 19S-10mm and the mall is slightly larger elevator wire rope 12mm13mm shopping malls Carrier lift, 12mm13mm16mm diameter elevator wire rope.
New factory wire rope most of the production has been carried out in the lubrication treatment, elevator wire rope working principle, under normal circumstances. But in the use of the process, the grease will be reduced. In view of the lubrication can not only on the wire rope during transport and storage play a role in preservative maintenance, and can reduce the use of wire between the wire, between the rope and the rope and the traction groove between the wear, and the use of extended wire rope Life is also very useful. Therefore, in order to erosion, wear on the hazards of wire rope to a minimum level, the lubrication inspection is necessary. First of all, we must choose the appropriate steel rope lubricating grease, elevator wire rope lubricating grease should be used with a certain coefficient of friction of the friction grease, high-performance steel wire rope lubricating oil is to maintain the rope to extend the life of the fundamental guarantee. Wire rope at work, the internal three-dimensional direction of the micro-friction, which requires a steel wire rope grease must have a strong osmotic seepage function that lubricants in the lubricating oil molecules anti-wear agent components can penetrate into each wire Above, elevator wire rope specifications. In the case of
In addition, the elevator wire rope grease must also have a strong adhesion function. To ensure that its average adhesion to each wire rope. There are several ways to lubricate the wire rope. There is a method of removing the wire rope into the lubricating oil at a temperature of 80,100 degrees for about 24 hours. The other is to brush the lubricant directly on the wire rope with a brush. Brushing method and distance to grasp, in general, about 12mm diameter wire rope, about 40 meters each painted about 1 kg of grease, brushing distance in about two weeks; another is the use of special steel rope lubrication equipment The steel wire is lubricated, this method is the most convenient, but the equipment has higher interest. What kind of lubricant and lubrication method should be used in detail should be based on the requirements of the rope manufacturer. At present, the elevator maintenance unit is really looking at the steel wire rope lubrication maintenance is not much, many units have been accustomed to replacing the new wire rope, without focusing on lubrication management. This is only one aspect of the requirement to ensure the safe use of the wire rope. In addition, the external requirements for the use of wire ropes such as: the appearance of the traction wheel groove wear, groove geometry to check to ensure that the rope during the operation so that it is always in good contact to reduce the friction To ensure the safe operation of the elevator.
