Embodiment 1

[0015] Example 1: 111.4 parts of base oil, 255.7 parts of base oil, 9.4 parts of ashless gas engine oil compounding agent, 0.005 part of antifoaming agent, and 0.5 part of pour point depressant;

[0016] In step A, add base oil 1, base oil 2, gas engine oil compounding agent, antifoaming agent, pour point depressant and other raw materials into the blending kettle in proportion, and stir and blend at 50°C for 40 minutes.

[0017] Step B is based on the above step A, adding 22.2 parts of balance accelerator and 0.2 part of nano-carbon, and stirring and blending at 40-50° C. for 35 minutes. Then negative pressure dehydration, filtration purification, packaging.

Embodiment 2

[0018] Embodiment 2: 19.8 parts of base oil; 251.5 parts of base oil; 10 parts of low-ash gas engine oil compounding agent; 0.005 part of antifoaming agent; 0.5 part of pour point depressant;

[0019] In step A, base oil 1, base oil 2, gas engine oil compounding agent, antifoaming agent, pour point depressant and other raw materials are added to the blending kettle in proportion, and stirred and blended at 50-60°C for 60 minutes.

[0020] Step B is based on the above step A, adding balance accelerator 22.2 and nano-carbon 0.2 in proportion, and stirring and blending at 40-50° C. for 35 minutes. Then negative pressure dehydration, filtration purification, packaging.

Abstract

The invention discloses a gas power type natural gas compressor lubricating oil composition. The composition is mainly prepared from, by mass, 10-30 parts of first base oil, 40-63 parts of second base oil, 6-12 parts of gas oil compound additives, 0.2-0.5 part of pour point reducer, 0.001-0.005 part of anti-foaming agent, 17-27 parts of balance promoter and 0.1-0.6 part of nanometer friction modifier. The composite has the advantages that one type of lubricating oil can be universally used for lubricating a gas power machine and a compressor, the service life of a gas power type natural gas compressor device is prolonged, mechanical conversion efficiency is improved, power consumption is lowered, the lubricating oil change period is prolonged, and the corresponding final waste discharge is reduced.

Description

technical field [0001] The invention belongs to the technical field of lubrication and relates to a lubricating oil composition for a gas-powered natural gas compressor. Background technique [0002] The lubrication of gas-powered natural gas compressors generally includes two parts: the gas power machine and the gas compressor. Due to the different working properties of the above two parts and the different ambient medium atmosphere during work, it is usually necessary to select different lubricating oils in order to To achieve the purpose of improving the mechanical efficiency of the equipment, prolonging the service life, saving energy and reducing consumption. The main functions of lubricating oil at work are: friction reduction, anti-wear, heat dissipation, sealing, buffering, rust prevention, cleaning, long-term neutralization, etc. Ordinary gas engine lubricating oil is not compatible with gas compressor lubricating oil, and there is no specific requirement for energ...
