Lubricating grease for traction type elevator

Abstract

The invention discloses a lubricating grease for a traction type elevator, and is characterized by comprising the following components in parts by weight: 10-15 parts of high-strength steel wire, 20-30 parts of iron ore, 30-50 parts of steel slag powder, 4-10 parts of reinforcing steel bars, 40-65 parts of cement, 12-19 parts of quartz sand, 4-9 parts of potash feldspar, 5-14 parts of graphite powder, 5-19 parts of iron powder, 8-12 parts of resin, 1-4 parts of polyvinyl chloride, 2-7 parts of magnesium metal, 2-8 parts of plastic and 3-6 parts of water. The lubricating grease obtained by themethod disclosed by the invention has high adhesion and permeability and is not easy to lose, the phenomenon of oil throwing and oil losing when the lubricating grease is used on the elevator is avoided, and has the characteristics of water resistance, protective property, oxidation resistance, corrosion protection and rust protection.

Description

technical field [0001] The invention relates to a lubricating grease used in a traction elevator. Background technique [0002] The elevator wire rope consists of steel wire and rope core. Its load-bearing capacity is mainly determined by the steel wire. The steel wire is made of high-quality carbon steel and can reach high strength after repeated cold drawing and heat treatment; the rope core is generally made of organic fibers (such as hemp , cotton), synthetic fiber, asbestos core (high temperature condition) or soft metal and other materials, impregnated with lubricating grease, used to increase the elasticity and toughness of the wire rope, when squeezed, it can secrete grease to lubricate the wire and reduce friction , improve the service life of wire rope. However, the steel wire rope newly put into use produces too much oil and slips on the traction sheave, causing the elevator to malfunction, and too frequent steel wire rope slipping can easily damage the traction ...

AI Technical Summary

Problems solved by technology

However, the steel wire rope newly put into use has too much oil, which slips on the traction sheave, causing elevator failure, and too frequent steel wire rope slipping can easily damage the traction sheave and steel wire rope, causing serious hidden dangers to the safety of the elevator

Moreover, under the working conditions with a lot of dust, the oil stains make it easier for the dust to adhere to the surface of the wire rope, which accelerates the wear of the wire rope.
