Description

Lubricating oil acid number on-line monitoring device

Technical Field

The utility model belongs to the technical field of lubricating oil acid number monitoring facilities, specifically indicate a lubricating oil acid number on-line monitoring device.

Background

The acid contained in the conventional lubricating oil mainly refers to organic acids (such as naphthenic acid, fatty acid, phenolic compounds, mercaptan and the like), inorganic acids (such as carbon dioxide, hydrogen sulfide and the like), caseins, endosaines, colloids, heavy metal salts, ammonium salts, other weak bases, acid salts of polybasic acids and the like. These materials are inherent in crude oil, as well as produced under storage and use conditions, and even include additives and their variations. Although there is no simple quantitative relationship between the acid number of the lubricating oil and the corrosiveness of the lubricating oil, the method is still widely used in the corrosiveness and quality characterization of petroleum and petroleum products because of the relative ease of measurement. Therefore, on one hand, the acid value is one of important indexes for controlling and reflecting the refining degree of the base oil, and the deeper the refining depth of the base oil is, the smaller the acid value is; on the other hand, the lubricating oil chemically reacts with oxygen in the air at a certain temperature during storage or use to generate a certain amount of organic acid. The larger the acid value of the lubricating oil is, the more the lubricating oil is deteriorated, and the index for determining the degree of deterioration of the lubricating oil is also used. However, as the lubricant industry has developed, many lubricating oils have been additized. For some lubricating oils to which an acidic additive (e.g., alkenyl succinic acid, etc.) is added, the acid value must be controlled within a certain range. If the acid value is lower than this range, the amount of the additive contained in the oil solution becomes insufficient. For a lubricating oil in use, the change in acid value reflects the consumption of additives and oxidation of the lubricating oil, which can greatly reduce the functionality of the lubricating oil.

However, the existing device for monitoring the acid value of lubricating oil mainly comprises GB/T4945 method for measuring the neutralization value of petroleum products and lubricants (color indicator method) and GB/T7304 method for measuring the neutralization value of petroleum products and lubricants (potentiometric titration method). The color indicator method has simple instrument and convenient operation, but has little change of the end point and large measurement error when measuring the acid value of the lubricating oil with dark color or added with the additive. The potentiometric titration method is characterized in that a potentiometric titrator is used for measuring the current amount of a titrated sample to record a measurable potential difference, the titration endpoint is determined mainly by observing potential mutation, titration can be carried out in colored, turbid or colloidal solution, and the potentiometric titration method has the advantages of quick detection and accurate result. However, the method is difficult to generate potential mutation in the non-aqueous system measurement, and the measurement effect is poor.
