System and method for testing oxygen content in industrial lubricating oil

Abstract

The invention discloses a system and a method for testing oxygen content in industrial lubricating oil. The system comprises a degassing vacuum tank, an inlet of the degassing vacuum tank is connected with an oil pipe through a metering pump, an outlet of the degassing vacuum tank is sequentially connected with a high-temperature tank and a detector, the degassing vacuum tank is further connected with a vacuum pump, and the bottom of the degassing vacuum tank is communicated with a nitrogen pipe; and the detector comprises a gas chromatographic analysis device for performing quantitative analysis on CO2 and CO in the mixed gas and a Karl Fischer micro-water meter for performing quantitative analysis on water in the mixed gas. The oxygen content in oil molecules can be accurately detected, a direct basis is provided for judging the aging degree of the oil, the oil quality of mechanical equipment is avoided, the monitoring level of the aging degree of the oil is greatly improved, and safe and economical operation of the equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of oxygen content testing in industrial lubricating oil, and in particular relates to a testing system and a testing method for oxygen content in industrial lubricating oil. Background technique [0002] Industrial lubricating oil mainly plays the role of lubrication, sealing, heat dissipation and insulation in mechanical and electrical equipment. The quality of your oil is critical to the safe, smooth and economical operation of your equipment. However, during the operation of the equipment, due to the influence of external temperature, oxygen, moisture, metal catalysis, etc., the oil will inevitably deteriorate and deteriorate, forming oxides, alcohols, aldehydes, acids, esters, hydroxy acids, etc. Products, macromolecular sludge formed by cross-linking between aging products is easy to precipitate and deposit on metal surfaces with low temperature. Carboxylic acid aging products are easy to cause corrosi...

Problems solved by technology

However, during the operation of the equipment, due to the influence of external temperature, oxygen, moisture, metal catalysis, etc., the oil will inevitably deteriorate and deteriorate, forming oxides, alcohols, aldehydes, acids, esters, hydroxy acids, etc. Products, macromolecular sludge formed by cross-linking between aging products is easy to precipitate and deposit on metal surfaces with low temperature. Carboxylic acid aging products are easy to cause corrosion of equipment in the presence of oil and water, thereby reducing equipment operation. reliability
