Problems solved by technology

[0004] The hydraulic oil currently used has low viscosity index, poor viscosity-temperature performance, and poor oxidation stability. At low temperatures, the oil becomes viscous, which increases energy consumption. Under extreme conditions, it causes wear and tear, which damages the parts and prevents them from working properly; Oxidation at high temperature shortens the life of the oil product, produces sludge, and clogs the filter device, making it difficult to meet the working conditions of the hydraulic system in a complex environment

Abstract

The invention discloses energy-saving engineering machinery hydraulic oil. The energy-saving engineering machinery hydraulic oil is prepared from, by weight, 0.2-0.9 part of tricresyl phosphate, 0.8-1.2 parts of antiwear agent, 4-6 parts of benzotriazole octadecylamine salt, 2-4 parts of ethylene glycol oleate, 75-85 parts of hydrogenated styrene isoprene copolymer, 1.5-2.5 parts of monoene succinimide, 1.5-2.5 parts of 2,5-di-tert-butylhydroquinone, 2.5-3.5 parts of 4,4'-dioctyl diphenylamine, 4-8 parts of polymethacrylate, 0.02-0.04 part of dimethicone and 850-950 parts of base oil. The energy-saving engineering machinery hydraulic oil has good wear resistance and can provide a lubrication guarantee in time at different working stages; equipment runs stably, pressure is evenly transferred, friction and abrasion are reduced, temperature rise is low, heat dissipation is rapid, power losses are reduced, energy consumption is reduced, and the oil replacement period is prolonged. The energy-saving engineering machinery hydraulic oil is suitable for hydraulic systems of various kinds of industrial equipment, engineering machinery, metallurgical machinery and the like.

Description

technical field [0001] The invention relates to a static hydraulic system, belongs to the technical field of hydraulic oil, and in particular relates to an energy-saving engineering machinery hydraulic oil. Background technique [0002] The level of energy consumption is a comprehensive reflection of a country's economic structure, growth mode, technological level, management ability, consumption pattern and national quality. The country's "Eleventh Five-Year Plan" "Outline" further set the "Eleventh Five-Year Plan" period to reduce energy consumption per unit of GDP by about 20% as a binding target, and six measures must be taken to save energy. "Energy saving through technological progress" is listed into it. Energy conservation is at the core of China's energy strategy and policies. my country's energy utilization efficiency is about 10% lower than that of advanced countries. Measured by energy economic efficiency indicators, the energy consumption per unit of product ...
