Elevator automatic door pulley assembly special-purpose lubricating oil

Abstract

The invention discloses an elevator automatic door pulley assembly special-purpose lubricating oil. The elevator automatic door pulley assembly special-purpose lubricating oil is composed of, by weight, 100 to 110 parts of base oil, 5 to 7 parts of a metal antiwear agent 5 to 6 parts of an anticorrosion antirust agent, 8 to 9 parts of a cleaning factor, 5 to 7 parts of an oiliness agent, 4 to 6 parts a metal antivator, and 5 to 7 parts of a viscosity conditioning agent. According to the elevator automatic door pulley assembly special-purpose lubricating oil, the base oil is prepared through mixing of mineral base oil, peanut oil, and sunflower seed oil, so that the cost of the base oil is controlled, and at the same time, preferable viscosity index and excellent wear resistance are ensured; adding of auxiliary agents is capable of removing black carbon mud particles used for coating contact surfaces of connecting rods effectively, providing hydraulic bumper connecting rods with the best protection, prolonging connecting rod service life, reducing equipment maintenance cost, providing elevator buffer connecting rods with clean wear protection mode. The steps of a preparation methodof the elevator automatic door pulley assembly special-purpose lubricating oil are simple and convenient, and are friendly to the environment.

Description

technical field [0001] The invention relates to the technical field of production of lubricating oil for elevators, in particular to a special lubricating oil for elevator automatic door pulley blocks. Background technique [0002] In recent years, with the advancement of urbanization and the improvement of residents' living standards, elevators have become an indispensable vertical transportation tool in people's production and life.

Problems solved by technology

[0005] The lubrication of the elevator plays a vital role in ensuring the safe operation of the elevator, saving energy and reducing consumption. Therefore, choosing a suitable lubricating oil product is one of the important tasks for elevator maintenance and maintenance. The parts that need to be lubricated in elevator equipment are more There are many, mainly including traction gearboxes, wire ropes, guide rails, hydraulic buffers, car door machines and other components. Each component of the elevator that needs to be lubricated has different requirements for lubricating oil. There are no special parts for elevators on the market. Lubricating oil, in the traditional elevator maintenance process, in order to save trouble and reduce management costs, the same lubricating oil is used for each component. If the lubricating oil is used incorrectly, it will bring greater safety hazards to the equipment and often damage it. increase maintenance cost
