Problems solved by technology

On the contrary, if the viscosity of the lubricating oil is too high, it will increase the internal friction force, increase the specific power of the compressor, and increase the power consumption and oil consumption. Formation of sediment
Compressor oil is prone to emulsification during operation, resulting in unclear separation of oil and gas and increased oil consumption. At the same time, the oil is emulsified to damage the oil film, which will cause increased wear
The screw air compressor that dominates the compressor, the lubricating oil used is in high temperature and high pressure environment in contact with the air for a long time, the lubricating oil is easily oxidized, causing the viscosity, acid value and sludge of the oil to increase, resulting in the operation of the compressor Fault

Abstract

The invention discloses a welding method of a stainless steel pipe plate and a copper pipe and relates to the technical field of lubricating oil. The screw compressor oil comprises the following components in percentage by weight: 1-5% of a borate antioxidant, 0.01-3% of a high-temperature ash-free anti-wear agent, 0.01-0.5% of benzotriazole, 0.01-0.5% of an antirust agent, 0.1-2% of a pour point reducer and the balance of hydrofined mineral oil. A preparation method of the screw compressor oil comprises the following steps: adding the hydrofined mineral oil into a reaction kettle, stirring for over 30 minutes while raising the temperature to 60 DEG C and uniformly mixing to obtain basic oil; and then, sequentially adding the borate antioxidant, the high-temperature ash-free anti-wear agent, benzotriazole, the antirust agent and the pour point reducer into the basic oil, maintaining the temperature of the kettle at 60 DEG C, at least further stirring for 1 hour till the mixture is fully dissolved uniformly. Compared with the prior art, the screw compressor oil provided by the invention has better high-temperature oxidation resistance and longer service life.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to lubricating oil for screw compressors and a preparation method thereof. Background technique [0002] Air compressor oil is mainly used for the lubrication of the moving parts of the compressor cylinder and the exhaust valve, and plays the role of anti-rust, anti-corrosion, sealing and cooling. Since the air compressor is always in the environment of high pressure, high temperature and condensed water, the air compressor oil should have excellent high temperature oxidation stability, low carbon deposition tendency, suitable viscosity and viscosity temperature performance, and good Oil-water separation, rust and corrosion resistance, etc. On the contrary, if the viscosity of the lubricating oil is too high, it will increase the internal friction force, increase the specific power of the compressor, and increase the power consumption and oil consumption. deposits are form...
