Q
What kind of lubricant can prevent wire rope damage?
A
First, the smooth oil has good fluidity and soaking ability, allowing it to quickly enter the inside of the rope and the rope core when the wire rope is smooth pretreated, and can play a role in preventing bacteria from multiplying inside the rope core fibers.
Second, the lubricating oil adhered to the wire rope will not be easily wiped off, and the smoothing effect will not be affected within the specified temperature range. In addition, the lubricating oil with adhesive function can also prevent skid, which provides assistance for the friction of the elevator wire rope.
Third, it has a high oil film strength, which can resist the extremely high pressure between the steel wires in contact with each other under extremely heavy load, and can also resist decomposition and transformation.
Fourth, smooth oil has high cohesion, which can avoid the dripping of smooth oil, centrifugal loss when there is no exercise, and avoid grease waste and pollution to other equipment.
Fifth, it does not contain ingredients that can cause corrosion and rust in the steel wire rope, and the effect of anti-corrosion and anti-rust is better.
Sixth, its self-correcting ability is strong. When the wire rope is used, it constantly twists and turns, which will cause the surface oil film to continuously knead and expand. This requires a soft and high-temperature oil film to maintain the rope body from cracking.
