Problems solved by technology

Mineral-type screw compressor oil is made from petroleum products after a series of fractionation, purification, refining, and adding various additives; ordinary mineral-type screw compressor oil has poor oxidation stability, and it is easy to form carbon deposits during actual use, which is difficult to meet Lubrication requirements for screw compressors under high working pressure and high heat load conditions
At the same time, due to the extremely low biodegradability of mineral screw compressor oil, it is difficult to decompose in nature, causing increasingly serious pollution to the natural environment

Abstract

The invention provides environmentally-friendly energy-saving-type heavy loading screw compressor oil. The environmentally-friendly energy-saving-type heavy loading screw compressor oil comprises 90-95% of composite base oil and 10%-5% of other additives in percentage by weight. Poly Alpha-Olefins (PAO) and dioctyl sebacate are compounded to serve as the base oil of the environmentally-friendly energy-saving-type heavy loading screw compressor oil. The environmentally-friendly energy-saving-type heavy loading screw compressor oil provided by the invention has the advantages of good operating characteristics, long service life and good biodegradability and also has effects of improving the efficiency of a screw compressor, reducing the abrasion and corrosion of a screw, effectively prolong the service life and the oil draining period of the screw compressor and meeting the requirements under special service conditions. The environmentally-friendly energy-saving-type heavy loading screw compressor oil provided by the invention is not only suitable for the requirements of various middle-heavy loading screw compressors under service conditions, and but also can meet the lubrication, cooling and sealing requirements of the middle-heavy loading sliding vane compressors.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving heavy-duty screw compressor oil. Background technique [0002] A screw compressor is a volumetric compressor that realizes gas compression by means of a change in working volume generated by the rotation of one or more rotors in the cylinder. Compared with reciprocating compressors, screw compressors generally do not have reciprocating inertial forces and moments, and have the advantages of high speed, simple structure, stable operation, high reliability, small size, light weight, and small gas pulsation; therefore, they have been widely used It is used in refrigeration, gas transportation, medicine, textile, food, mining metallurgy, construction machinery and other fields. In recent years, with the enlargement of screw compressor equipment and the development towards heavy load, large flow, high speed, high temperature, and high pressure operation, higher requirements have been put fo...
