A boom lubrication process

Abstract

The invention discloses a boom lubricating process, comprising the following steps: A. Filling clean molybdenum disulfide lubricating grease into the oil storage cylinder of an electric lubricating pump, the penetration of the lubricating grease is 265-385 (25°C, 150g) 1 / 10mm, the electric lubricating pump stirs and softens the lubricating grease delivered to the oil storage tank with blades, and then presses the lubricating grease out from the oil outlet through the oil pump cylinder, the nominal pressure is: 38 ~ 42MPa, after High-pressure oil delivery hose to the spray gun; B. With the boom fully extended, the worker holds the spray gun to spray grease on the outer and inner surfaces of each boom. The thickness of the grease is 0.8-1.2mm, and the rated spraying distance is: 180~220mm, rated injection diameter: 110~130mm, compressed air pressure: 0.4~0.6MPa, distance between spray gun and lubricating machine trolley: 0~15 meters, grease injection volume: 420~440ml / min. The invention is a boom lubricating process with high working efficiency, good working quality, low labor intensity, saving lubricating grease and protecting the environment.

Description

technical field [0001] The invention relates to a lubricating process, in particular to a lubricating arm lubricating process. Background technique [0002] The lubrication of the boom, an important part of the truck crane, is not only very important, but also requires a large amount of grease. In the past, due to limited conditions, this work was done manually by workers, which has the following disadvantages: [0003] 1. Low work efficiency: The lubrication work on the outside of the boom is done by workers holding ZFG-4E grease on the boom with both hands, and the inside of the boom is lubricated with a stick wrapped in cloth and greased , applied after entering from the boom craft hole. Therefore, it takes about 1 hour to complete the lubrication task of a boom assembly. [0004] 2. Poor quality of work: Because it is manual operation, the quality of application is very poor, the thickness is uneven, and the places with thick grease are often scraped off after the boom...

AI Technical Summary

Problems solved by technology

[0004] 2. Poor work quality: because it is manual operation, the quality of application is very poor, the thickness is uneven, and the places with thick grease are often scraped off after the boom stretches, which does not play a lubricating role

[0005] 3. High labor intensity: A boom assembly is about 40 meters long after it is fully extended. Workers need to apply grease to the boom one by one, so the labor intensity is relatively high.

[0006] 4. The process is backward: due to the above reasons, the backward nature of this process is proved, which can be seen intuitively from the operation of the workers, so it is required to improve the original process

[0007] 5. Lubricating grease waste and environmental pollution: Due to the uneven thickness of manually applied grease, in fact, a large amount of grease coated on the boom is often scraped off after the boom stretches, and then falls to the ground, which is a waste of time. Lubricating grease pollutes the production environment
