The wire rope use maintenance is very important, do the job, not only can prolong service life, and can improve work efficiency, and the prevention of accidents. In the process of using in maintenance, mainly refers to the wire rope lubrication and anticorrosion coating of oil.
A: the wire rope lubrication
Wire rope in manufacturing, has put enough oil, but the operation, grease can reduce gradually, and the wire rope occupies the dust and debris surface will respect, cause steel wire and rope round of wear and wire rope rust, therefore, should be regularly cleaned and gas. Simple and easy method is to choose wire brush and other corresponding tools such as dust on the surface of the wire rope erase dirt, putting the heating to melt the wire rope surface fat evenly spread in the surface of wire rope.
In the production process, we will lubrication of wire, in order to make shares and shares within the steel wire rope with mobile and can bend and automatic adjustment. However the production process of lubrication cannot guarantee wire rope in the whole life cycle use sufficient lubrication. Therefore, in service life time of wire rope lubricated is very important.
In the operating process, the surface of the rope will cover clay, stone dust or other substances. This will stop the oil seeping into the wire rope on the scene, therefore, in lubrication necessary wire rope before cleaning.
Low viscosity oil should be used, like this can seep into wire core. Usually there are three kinds of lubrication methods: trickle-down, spray, hand brush type. Whatever the way, should be in the bend wire rope, such as tank round place, lubrication. We suggest you bend in the top of the use of lubrication oil, because the position in the rope of bending because stretch, and are more likely to penetration. In addition, in the business can be pressure lubrication way. Wire rope service life and you use lubrication method and lubrication of the effectiveness of the quantity directly related.
Proper lubrication must be able to reduce the friction, prevent corrosion and adhesion in each wire. At the same time must be flexible, encounter cold no crack or cracking encounter heat, no drop. Avoid by all means use of wire much oil, because that will make wire rope and adhesion hard tool friction, and damage wire rope. Also avoid using the machine used oil, because it contains damaged wire rope material. If special, you can set we in the production of the special oil.
B: daily inspection
Because of wire rope not only load bearing, fatigue, wear, and working conditions, so use daily maintenance maintenance and inspection is very important. Maintenance and inspection of the main contents are as follows:
1, regularly for wire rope filling besmear with rust and lubrication grease.
2, regularly cleared surface dirt and other wire rope with impurity oil dirties.
3, daily inspection and record the wire rope wear, broken wires, rust, oil, deformation, diameter and other abnormalities.
4, wire rope inspection should be done before use. When the wire rope wear, broken wires, broken stocks, rust, stretching, bending, deformation, fatigue, diameter, wire core shows the degree of relevant regulations sets to the replacement of the standard, the change in time new lines.
C: maintenance note:
The wire rope use period and method of use have very big concern, so should be used according to regulations, banned drag, throwing, use no overload, not make wire rope happen acute Angle flex, not change dramatically and speed, avoid impact load;
Wire rope is rust and grey scale, use wire brush to brush to and with oil; |
Every use wire rope four months with oil once, with oil, had better use hot when oil (50 ℃ or so) soak wire core, then wipe excess oil;
Wire rope tape should be put in a dry and clean after the place, not overlap piled up, prevent sprain;
At the end of the wire rope tied with steel wire or use the low melting point of the alloy solder firm, also can use onononmetal straps GuJin, lest rope loose head;
Use, such as a wire rope surface oil droplets extrusion, said the wire rope has considerable power under and, at this point, should stop to increase the load, and checked and, when necessary, replace new wire rope.
