Abstract

The invention relates to a turbo compressor oil composition which is particularly suitable for a combined lubrication system of a turbo rotary compressor for lubricating compression ammonia or ammonia synthesis gas. The combined lubrication system comprises a turbine bearing, an accelerator, a flexible coupling and an oil seal. The turbo compressor oil composition comprises the following components in parts by mass: 3-5 parts of magnochromite, 1-2 parts of enstatite, 1-2 parts of terbium oxide, 1-2 parts of vinyl triacetoxysilane, 1-2 parts of neutral petroleum calcium sulfonate and 83-93 parts of turbo compressor oil. By virtue of the prepared turbo compressor oil composition, a cylinder, an exhaust valve, a crankshaft bearing, a connecting rod, a crosshead and a slide plate surface can be provided with a super-corrosion-resistant hard metal ceramic wear-resistant layer, so that a turbo compressor can operate smoothly, the failure rate is reduced, and the service life is longer than twice.

Description

technical field [0001] The invention relates to a turbine compressor oil composition, which is especially suitable for the combined lubrication system of a turbine rotary compressor for lubricating compressed ammonia or ammonia synthesis gas, including steam turbine bearings, accelerators, flexible couplings and oil seals. Background technique [0002] The working characteristic of the compressor is to compress the gas. The turbo compressor is mainly used to compress ammonia or ammonia synthesis gas, and its lubrication system can be divided into internal (cylinder, exhaust valve) lubrication and external (crankshaft bearing, connecting rod, crosshead, slide plate). The larger the compression ratio of the turbo compressor, the higher the temperature rise, the lubricating oil is easily oxidized, the viscosity increases, and the formed paint film and carbon deposit will make the moving parts sluggish. In a corrosive atmosphere, cylinders, exhaust valves, crankshaft bearings, ...
