Abstract
The invention relates to novel lubricating oil for a hydraulic machine. The lubricating oil is prepared from the following components in parts by weight: 68 to 87 parts of base oil; 3 to 6 parts of polyurethane; 6 to 12 parts of diethyl phosphite with the concentration being 1 to 3 mmol / 100g; 0.8 to 1.3 parts of chloroform; 4 to 9 parts of a tackifier; 8 to 11 parts of dibutyl phosphite with the concentration being 1 to 3 mmol / 100g; 6 to 9 parts of talcum powder; 11 to 14 parts of phosphoric acid; 0.5 to 0.7 part of benzotriazole; 1.2 to 2.1 parts of sorbitol; 1.6 to 1.9 parts of di-iso-octyldiphenylamine; 0.7 to 1.5 parts of an oxidation and corrosion inhibitor. The lubricating oil has the advantages that the lubricating oil formula is simple, raw material are easy to get, the abrasion resistance is excellent, the problem that the existing lubricating oil is low in viscosity index is solved, the cooling and lubricating effects are good, the frictional force is small when the lubricating oil is used, the lubricating oil has good cooling, sealing, preservative, rust-proof and insulating effects on machinery equipment, the frictional force is small when the lubricating oil is used, and the lubricating effect is good.
Description
technical field [0001] The invention relates to the field of hydraulic machines, in particular to a novel lubricating oil for hydraulic machines. Background technique [0002] A hydraulic press is a machine that uses liquid as a working medium to transfer energy to achieve various processes. In addition to being used for forging and forming, the hydraulic press can also be used for straightening, pressing, packing, briquetting and pressing. Hydraulic presses include hydraulic presses and hydraulic presses. The hydraulic press that uses water-based liquid as the working medium is called hydraulic press, and the one that uses oil as the working medium is called hydraulic press. The specifications of hydraulic presses are generally expressed by nominal working force (kN) or nominal tonnage (tons). Most hydraulic presses for forging are hydraulic presses with high tonnage. In order to reduce the size of the equipment, large-scale forging hydraulic presses often use higher pr...
