Observe the lubrication of wire rope:
Wire rope is usually lubricated during processing, including surface lubrication and internal lubrication, which can protect the wire rope from corrosion, avoid internal steel wire and dry friction, and also lubricate the inner and outer surfaces of the wire rope during movement. Initial lubrication can be maintained for a long time. When poor lubrication of wire rope or lack of lubricating oil is observed, it is necessary to refuel in time. When lubricating, we should pay attention to the different degree of wear and the different grease used.
① When the steel wire rope slides on the pulley or rolls on the drum, SAE30W is generally used, which can penetrate into the gap of the rope for effective lubrication.
② When the wire rope is seriously worn, use high-viscosity grease to reduce mechanical wear, such as high-viscosity oil or light grease containing graphite and molybdenum disulfide adhesive additives.
(3) when the wire rope comes into contact with loose abrasive (soil, sand, etc.). ), the lubricating oil (grease) outside the wire rope will stick to these objects, resulting in serious wear of the wire rope and pulley. In this case, the surface of wire rope must be cleaned and lubricated in time.
Lubrication method of wire rope: bathe the rope constantly, that is, let the rope slide through the container filled with lubricating oil and wipe off the excess oil on the rope with a cloth; Brush the rope with oil or grease with a cloth or brush; Use a spray gun to lubricate the rope.
