How to lubricate the wire rope rigging regularly? [answered]

Due to the poor service environment of wire rope rigging, the wire rope is corroded and worn. Therefore, regular lubrication should be carried out in the process of production and use, which can effectively prolong the service life. Firstly, the rope core oil, surface oil and rope surface oil shall be treated in the production process. Oil immersion of rope core is an important work in the production of steel wire rope rigging. Before oil immersion, the rope core shall be carefully dried to water, and the oil content of rope core shall be increased as much as possible. The oil content depends on the dryness of the core, oil temperature and oil immersion time.

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 process of vacuum pressure oil immersion is complex, but the rope core coil can be immersed in oil. The rope core is immersed in oil evenly and has high oil content. The immersion temperature of the core varies with different immersion methods. The surface oil can be sprayed when twisting strands and connecting ropes, or soaked after connecting ropes. Spraying is to pressurize and heat the molten liquid oil through the oil pipe to the joint between the twisting machine and the rope machine, and inject it into the twisting cone to fill the free space between the steel wire and the strand. The spraying device can also be configured separately according to the machine. The surface of steel wire rope shall be coated with oil by spraying method.

The method of dip coating and pouring coating on the surface of steel wire rope rigging is to set an oil groove between the traction wheel of the rope take-up machine and the wire drawing machine, press the wound steel wire rope into the molten grease for oil coating, or absorb oil through the oiler installed above the oil groove, and then sprinkle oil on the surface of the steel wire rope. This oiling method is easy to cause missing coating on the surface of wire rope rigging, 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 use pouring method to lubricate the steel wire in the strand when twisting the strand, so as to improve the quality of the surface coating of the steel wire rope.
