Nano metal self-restoring lubricating oil for mechanical sealing element and preparation method thereof

Abstract

The invention discloses nano-metal self-repairing lubricating oil for mechanical seal elements and the process for preparation, which comprises the following components, the weight percentage content which occupies the total amount of self-repairing lubricating oil is that nano-metal powder which is 0.07-0.15%, nano-metal powder body dispersing agent which is 0.2-1% and disperse medium 98.9-99.7%. The process for preparation of the invention comprises the following steps: adding nano-metal powder body dispersing agent which is needed by proposition into disperse medium to evenly stir, furtheradding nano-metal powder according to the above proposition, properly stirring till nano-metal powder has no obvious settlement, placing with a container into a KH-700 type ultra-audio wave oscillator to oscillate 20-30 minutes, wherein source of power is 500-600w, and getting product. The nano-metal self-repairing lubricating has low production cost, which is beneficial for popularizing, and canlead the gap between friction pairs to be optimized, and the nano-metal self-repairing lubricating oil can not be dropped off after a self-repairing layer is formed, operation with low friction factor of equipment is kept, and the nano-metal self-repairing lubricating oil is energy-saving and environmental-friendly, which can effectively prolong maintenance down periodic time, and lowers maintenance cost.

Description

technical field [0001] The invention relates to a new type of nano-metal self-repairing lubricating oil suitable for various friction pairs in mechanical seals. The applicable friction pairs include graphite / steel, steel / steel, hard alloy / hard alloy, SiC / SiC, poly Tetrafluoroethylene / Al 2 o 3 , Graphite / SiC. Background technique [0002] According to reports, 30% to 50% of the world's production energy is lost on friction and wear, and China's annual loss due to friction and wear reaches hundreds of billions of yuan. Therefore, reducing friction, reducing wear, improving equipment utilization, and prolonging service life have always been one of the important research contents of countries all over the world. In mechanical seals, the oil used for sealing and lubricating has a great influence on the service life and energy consumption of the product. The friction of the sealing section will consume mechanical power and reduce mechanical efficiency; the occurrence of wear w...

Problems solved by technology

However, industrial supplies have a wider user base. Mechanical seals are common consumables in chemical, agricultural, metallurgical and other industries. Too much damage leads to frequent maintenance and replacement, which seriously affects the efficiency of equipment.

In addition, for the improvement of industrial supplies, the cost should be considered firstly. Too much cost increase is not suitable for industrial promotion
