The maintenance of wire rope in use is very important. Doing a good job in this aspect can not only prolong the service life, but also improve the work efficiency and prevent accidents
happen. In the process of using maintenance, mainly refers to the wire rope lubrication and anti-corrosion oil.
1： Lubrication of wire rope
The steel wire rope has been coated with enough grease during manufacturing, but the grease will gradually reduce after operation, and the surface of the steel wire rope will occupy dust, debris and other dirt, causing damage
The wire rope and pulley are worn and the wire rope is rusty. Therefore, it should be cleaned and refueled regularly. The simple method is to use wire brush and other corresponding tools to wipe off the wire rope
For dust and other dirt on the surface, evenly apply the heated melted grease on the surface of the wire rope.
In the production process, we will lubricate the steel wire rope, so that the strand and each steel wire in the strand can automatically adjust with the movement and bending of the steel wire rope
The process lubrication can not guarantee the full lubrication of the wire rope in the whole service life cycle. Therefore, it is very important to lubricate the wire rope regularly in its service life.
During operation, the surface of the rope will be covered with soil, stone chips or other substances. This will prevent the lubricating oil applied on site from penetrating into the wire rope, therefore, during lubrication
It is necessary to clean the wire rope before operation.
The lubricating oil used should be low consistency so as to penetrate into the core. There are usually three ways of lubrication: drip, spray and hand brush. No matter what method is used
Methods, should be in the wire rope bending, such as groove wheel, lubrication. We suggest that you use lubricating oil at the top of the bend, because this position is the center of the rope
Bend and stretch, and more permeable. In addition, pressure lubrication is also commercially available. The service life of steel wire rope depends on the lubrication method and amount you adopt
It is directly related to the effectiveness of.
Proper lubrication must reduce friction, prevent corrosion, and adhere to each wire. At the same time, it must be flexible, no crack or crazing when it is cold, no dripping when it is hot.
Do not use too much grease on the wire rope, because it will cause friction between the wire rope and the attached hard objects, which will damage the wire rope. Do not use the used machine lubrication
Oil, because it contains substances that damage the wire rope. If the situation is special, you can stipulate that we use special lubricating oil in production.
: daily inspection
Because the wire rope not only bears load, fatigue and wear, but also works in bad environment, so daily maintenance and inspection are very important. Maintenance
The main contents of inspection are as follows:
1. The steel wire rope shall be coated with anti rust and lubricating grease regularly.
2. Regularly remove the oil dirt with dust and other impurities on the wire rope surface.
3. Daily inspection and record of wire rope wear, broken wire, corrosion, grease, deformation, diameter and other abnormalities.
4. The wire rope should be checked before use. When the wire rope is worn, broken wire, broken strand, corroded, stretched, bent, deformed, fatigued, diameter and core exposed
When the rope reaches the replacement standard specified in relevant regulations, a new rope shall be replaced in time.
3： Maintenance precautions:
The service life of wire rope has a great relationship with the method of use, so it should be used according to the regulations, and it is forbidden to drag and throw. It is not allowed to overload or throw in use
It is not allowed to change the lifting speed sharply to avoid the impact load;
When there is rust and ash on the wire rope, brush it with wire brush and apply oil;
The steel wire rope should be oiled every 4 months. It is better to soak the rope core with hot oil (about 50 ℃), and then wipe off the excess grease;
After coiling, the wire rope shall be placed in a clean and dry place, and shall not be overlapped to prevent sprain;
The end of the wire rope shall be tied tightly with steel wire or welded firmly with alloy with low melting point, or hooped tightly with iron hoop to avoid loosening of the rope end;
In use, if oil drops extrude from the surface of the wire rope, it means that the wire rope has withstood considerable force. At this time, stop increasing the load and check if necessary
Replace the wire rope with a new one.
