Description

A kind of anti-breakdown of emulsion synthetic hydraulic fluid improving quality

Technical field

The present invention relates to technical field of hydraulic pressure, particularly relate to a kind of anti-breakdown of emulsion synthetic hydraulic fluid improving quality.

Background technology

In recent years, along with design of Hydraulic System, manufacturing technology development and be gradually improved, hydraulic technique is widely used in mechanical means of new generation.The polytropy of hydraulic machinery operating environment, very large challenge is brought: hydraulic efficiency oil must bear the test of high pressure-temperature, temperature variation, severe environment to hydraulic efficiency oil, need excellent viscosity temperature characteristic and higher supporting capacity, ensure working efficiency and the work-ing life of machinery, but existing antiwear hydraulic oil is difficult to meet hydraulic efficiency system operating mode complicated and changeable completely.Present widely used antiwear hydraulic oil, viscosity index is lower, and viscosity temperature characteristic is poor, and the hydraulic efficiency oil being applicable to summer in winter life-time service is less, need change hydraulic efficiency oil when difference variation is larger; Oxidation Stability is unstable, and oxidation at high temperatures produces greasy filth, blocking purolator; Supporting capacity is not enough, can not bear larger impact load.

By on the base oil to multiple base oil, viscosity modifier, oxidation inhibitor, Additives Property in Lubricants evaluation in " development of the multistage antiwear hydraulic oil of high-performance " literary composition, by theoretical and experimental study, have developed a kind of multistage antiwear hydraulic oil, widen the temperature applicability of hydraulic efficiency oil, improve work-ing life of hydraulic machinery, extend hydraulic efficiency oil duration of service, save energy.But along with the reinforcement of people's environmental consciousness and the increasingly stringent of environmental regulation, the exploitation of Biodegradable lubricant oil and use more and more cause the extensive concern of people, and the biological degradability of most hydraulic basis oil is poor, belong to bio-refractory lubricant.Do not set forth for the degradability of hydraulic efficiency oil and the oxidation-resistance of degradable base oil in this article.

In the course of the work, because operating environment is severe, longevity of service, is often in high temperature, higher load condition to hydraulic efficiency oil, so higher to itself performance requriements.Wherein there is a very important problem to be exactly that hydraulic efficiency oil is easy to be mixed into water at work, after the water entering fuel tank is subject to the vigorous agitation of the Hydraulic Elements such as oil pump, motor, easily form emulsion.If this emulsion is stable, then can accelerates the rotten of hydraulic efficiency oil, reduce oilness, resistance to abrasion, generate clogging deposits strainer, pipeline, valve etc., also corrosion, corrosion can occur.Therefore, require that hydraulic efficiency oil has good resistance to emulsion, hydraulic efficiency oil can be separated with water quickly in other words, makes depositing in water to tank bottoms, then regularly discharges, and avoids the formation of stable emulsion.The demulsification performance of hydraulic efficiency oil can badly influence the reliability and stability of hydraulic work system.
