How to lubricate the steel wire rope regularly

Due to the poor service environment of wire rope rigging, which leads to the corrosion and wear of wire rope, regular lubrication should be carried out in the production and use process, which can effectively prolong the service life. First, the rope core oil, surface oil and rope surface oil should be treated in the production process.

Soaking the rope core in oil is an important work in the production of steel wire rope rigging. Before soaking in oil, the rope core should be carefully dried to water, and the oil content of the rope core should be increased as much as possible. The oil content depends on the drying degree, oil temperature and oil soaking time of the core. Generally speaking, the higher the oil content of the rope core, the better. The rope core with large oil content can not only improve the lubrication condition inside the steel wire rope, but also prevent the rope core from mildew, deterioration and decay.

Rope core oil immersion method is divided into atmospheric pressure oil immersion method and vacuum oil immersion method. It is easy to absorb oil under normal pressure in the oil tank, but it is not easy to absorb oil inside the coil, and the oil is uneven. The vacuum pressure oil immersion process is complex, but the rope core coil can be immersed in oil, and the rope core is evenly immersed in oil with high oil content. The immersion temperature of the core varies with the immersion method.

The surface oil can be sprayed when twisting strands and connecting ropes, or dipped after connecting ropes. Spraying is to pressurize and heat the molten liquid oil through the oil pipe to the joint of the twister and the rope machine, and inject it into the twister cone, so that the oil fills the free space between steel wires and strands. The spraying device can also be configured separately according to the machine. The surface of steel wire rope is coated with oil by spraying.

The method of painting, dipping and pouring on the surface of steel wire rope rigging is to set an oil groove between the traction wheel of the rope collector and the wire drawing machine, press the wound steel wire rope into the molten grease to apply oil, or absorb oil through the oiler installed above the oil groove, and then sprinkle oil on the surface of the steel wire rope. This kind of oiling method is easy to produce holiday coating on the surface of wire rope, and can only be applied on the surface of wire rope. Poor coating of inner layer and inner layer of wire rope will affect the service life of wire rope. In order to make up for the deficiency of this method, it is suggested to lubricate the steel wire in the strand by pouring method when twisting the strand, so as to improve the quality of the surface coating of the steel wire rope.
