Abstract

It is compound as fully synthetic composite foundation oil using the B-mode polyethers of the perfluor of mass ratio 50% and 50% perfluor y type polyethers the invention discloses a kind of liquid oxygen delivery pump lubricant compositions, coordinate two kinds of compound additives：Antirust agent and antioxidant preservative.The composition of the present invention has the performances such as good thermal oxidation stability, antioxidant, encapsulant intermiscibility, low temperature flow and diffusivity, anti-bubble, emulsion resistance, antioxygen anti-corrosion, tarnish protection, anti-strong-electromagnetic field.

Description

A kind of liquid oxygen delivery pump lubricant compositions
Technical field
A kind of liquid oxygen delivery pump lubricant compositions of the present invention belong to bearing lubricant field.
Background technology
Liquid oxygen pump is a kind of cryogenic liquid oxygen delivery pump, the pressure so as to improving liquid oxygen, reaches the purpose of conveying liquid oxygen.It is logical The liquid oxygen circulating pump often decided in condenser/evaporator, the technique liquid oxygen delivery pump between the upper and lower tower being arranged in juxtaposition, Internal-compression flow Product liquid oxygen pump and basin liquid oxygen.General liquid oxygen pump can be divided into two major classes, i.e., centrifugal and plunger type.Plunger type is typically used In conveying low discharge, the liquid of High Voltage.Centrifugal liquid oxygen pump big flow, mesolow air-separating plant in by extensively should With.Centrifugal liquid oxygen pump divides single-stage and multistage pump again.Part of the liquid oxygen pump as air separation separating device, for circulation fluid Oxygen or from storage tank extract liquid oxygen enter vaporizer, the gaseous oxygen of vaporization is conveyed to user under stress.Typically liquid oxygen pump is By：Support, transmission mechanism, cross head assembly, the pump housing, cylinder sleeve and plunger, pump head and tapping valve, airtight and watertight padding, liquid filter Deng eight most of compositions.Liquid oxygen conveying pumping lubricant requires anti-high oxidative, anti-knock properties, anti-strong-electromagnetic field, sealing material Expect the performances such as intermiscibility, low temperature flow and diffusivity.
The content of the invention
There is good thermal oxidation stability, anti-high oxidative, anti-knock properties, sealing material it is an object of the invention to provide a kind of Expect intermiscibility, low temperature flow and diffusivity, anti-bubble, emulsion resistance, antioxygen anti-corrosion, tarnish protection, the liquid oxygen of anti-strong-electromagnetic field performance Delivery pump lubricant compositions.
The present invention adopts the following technical scheme that solution above-mentioned technical problem：
A kind of liquid oxygen delivery pump lubricant compositions, using the B-mode polyethers of the perfluor of mass ratio 50% and 50% perfluor y Type polyethers as fully synthetic composite foundation oil, coordinate a variety of compound additives, its each mass percent composition composition：
Component Mass percentage content
Base oil Surplus
Antioxidant preservative 0.08%~2.1%
Antirust agent 0.08%~2.1%
The mass percentage content of above each component is 100%.
Antioxidant preservative be mass ratio 50% benzimidazole and 50% perfluorophenyl phosphorus it is compound.
Antirust agent be mass ratio 50% perfluoro octyl sulfonic acid and the double octyl diphenylamine DDPA of 50% P, P- it is compound.
The advantage of the invention is that：Liquid oxygen delivery pump lubricant compositions of the present invention have good thermal oxidation stability, Anti- high oxidative, anti-knock properties, antioxidant, encapsulant intermiscibility, low temperature flow and diffusivity, anti-bubble, emulsion resistance, antioxygen are prevented Corruption, tarnish protection, anti-strong-electromagnetic field performance.
