Maintenance is very important in the use of wire rope, do a good job in this area, not only can prolong the service life, but also can improve work efficiency and prevent accidents. Maintenance in the process of using, mainly refers to the steel wire rope lubrication and rust proof oil etc..
Lubrication of steel wire rope
In the manufacture of wire rope has been coated with enough oil, but after running, oil will be gradually reduced, and the steel wire rope surface dust, dirt and other debris may have caused, wire rope and rope wire rope wheel wear and rust, therefore, should be cleaned regularly and refueling. The simple method is to use wire brush and other appropriate tools to wipe off the dust of the wire rope surface dirt, the heating of the wire rope surface grease evenly coated on the surface of the wire rope.
In the production process, we will be on the wire rope lubrication, in order to make the strands and strands of steel wire rope with the movement and bending and automatic regulation. However, the lubrication of the production process can not guarantee the full lubrication of the steel wire in the whole life cycle. Therefore, it is very important to lubricate the steel wire rope in the service life.
During the operation, the surface of the rope will cover the earth, stone or other material. This will hinder the application of the lubricating oil into the steel wire rope, therefore, before the need to clean the wire rope.
The lubricating oil should be low consistency, so as to penetrate the rope core. There are usually three kinds of lubrication methods: drip, spray type, hand brush type. No matter what the way, should be in the wire rope bend, such as the groove wheel, the lubrication. We recommend that you use the lubricating oil at the top of the bend, because the position of the rope is stretched, and it is easier to penetrate. In addition, the business can also be pressurized lubrication. The service life of the wire rope is directly related to the effectiveness of the lubrication method and the amount of lubrication.
Proper lubrication must be able to reduce friction, prevent corrosion, and adhere to each wire. At the same time must be flexible, no crack or crack, cold heat without dripping. Do not use too much grease on the wire rope, because this will make the wire rope and the friction of the attached hard material, thereby damaging the wire rope. Also avoid the use of the use of machine lubricants, because it contains the material damage to the wire rope. If the situation is special, you can specify that we use a special oil in the production of.
Two: daily check
Because the rope not only bear the load, fatigue, wear, and the working environment is bad, so the use of daily maintenance and inspection is very important. Maintenance and inspection of the main contents are as follows:
1, regularly for steel wire rope coating with rust and lubrication of grease.
2, regularly remove dirt surfaces of steel wire rope with dust and other impurities.
3, daily inspection and record the wear of wire rope, broken wire, corrosion, grease, deformation, diameter and other abnormal conditions.
4, the wire rope should be checked before use. When the steel wire rope wear, broken wires, broken strands, corrosion, tensile, bending, deformation, fatigue, diameter, the extent of the exposed rope core to meet the requirements of the relevant regulations, the timely replacement of the new rope.
Three: maintenance notes:
Have a great relationship with the use of wire rope term and use method, therefore should be required to use, do not drag, throwing, use no overload, are not allowed to make wire rope sharp bend, no sharp change of lifting speed, avoid impact load;
The wire rope is rust and dirt, use wire brush to | and oil;
Wire rope oiling every 4 months once, preferably with hot oil when the oil (50 DEG C) with rope core, and then wipe excess oil;
Steel wire rope should be placed in a clean and dry place, do not overlap, prevent strain;
At the end of the wire rope with wire or tie with a low melting point alloy welding, can also be used to avoid the iron hoop, rope loose;
In use, the steel wire rope surface, if there is oil drop out, that the wire rope has a considerable strength, this time should be stopped to increase the load, and carry out inspection, if necessary, replace the new steel wire rope.
