How to Lubricate Wire Rope Slings Regularly
2022-02-10
Due to the harsh operating environment of the wire rope rigging, the wire rope is corroded and worn, so it should be lubricated regularly during 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.
Rope core oil immersion is an important task in the production of wire rope rigging. Before immersion 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 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 high oil content can not only improve the lubrication condition inside the wire rope, but also prevent the rope core from getting moldy, deteriorating and rotting. The rope core oil immersion method is divided into atmospheric oil immersion method and vacuum oil immersion method. It is simple and easy to absorb oil under normal pressure in the fuel tank, but the inside of the coil is not easy to be absorbed by the oil, and the oil is uneven. The vacuum pressure oil immersion process is complicated, but the rope core coil can be immersed in oil, the rope core is evenly immersed in oil, and the oil content is high. The immersion temperature of the core varies with the immersion method. The surface oil can be sprayed during twisting and splicing, or can be dipped after splicing. Spraying is to 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, so that the oil fills the free space between the steel wire and the steel wire and between the strands. The spraying unit can also be configured individually according to the machine. The surface of the wire rope is oiled by spraying. The method of dipping and pouring coating on the surface of wire rope rigging is to set an oil groove between the traction pulley of the rope take-up machine and the wire drawing machine, and press the wound wire rope into the molten grease for oiling, or install it above the oil groove. The oiler absorbs oil, and then spreads oil on the surface of the wire rope. This oiling method is prone to leak coating on the surface of wire rope rigging, and can only be oiled on the surface of the wire rope. The inner layer of the wire rope and the inner layer of the wire rope are not well coated, which will affect the service life of the wire rope. In order to make up for the insufficiency of this method, it is recommended to use the casting method to lubricate the steel wires in the strands during twisting, so as to improve the quality of the surface coating of the steel wire rope. |
