Problems solved by technology

[0003] The existing lubricating grease on the market can only be kept for lubrication for one week, and the effective time is short. If the lubricating grease is not reapplied in time, the lubricating effect of the telescopic arm will be reduced, resulting in certain safety hazards; at the same time, the high frequency of applying grease , on the one hand, it will affect the work efficiency, on the other hand, it will increase the cost

Abstract

The invention discloses special oil for maintenance of a telescopic boom of a crane and a preparation method thereof, and the special oil for maintenance of the telescopic boom of the crane comprises 60-80 parts of base oil, 5-15 parts of a thickening agent, 25-40 parts of graphite powder, 5-10 parts of lubricating grease, 1-5 parts of an anti-wear reagent at extreme pressure, 1-3 parts of an antioxidant, 1-5 parts of an antirust agent, 0.5-2 parts of a water repellent agent and 1-3 parts of a filler. The graphite powder is added, the pressure resistance of the lubricating grease can be improved and the moisturizing period of the lubricating grease can be prolonged, and a good lubricating effect is achieved for a long time, and the lubricating duration can reach about 20 days.

Description

Technical field [0001] The present invention relates to the field of lubricating processing, and more particularly to a crane telescopic arm maintenance special oil and a preparation method thereof. Background technique [0002] Crane telescopic arm is typically a plurality of sleeves, and is intervals from nylon blocks. During the routine operation, the crane needs to be lubricated with the telescopic telescopic arm to be lubricated, and the telescopic arm is telescopic, so that the telescopic arm is maintained in time, preventing the nylon block from being worn or damaged, and extension the equipment. cycle. [0003] On the market, the existing grease can only be stored for a week, and the effective time is short. If it is not re-applied to the grease in time, it will cause a reduced lubrication effect of the telescopic arm, generate a certain safety hazard; at the same time, high frequency application grease On the one hand, it will affect work efficiency, and on the other han...
