OA800 oil analysis spectrometer is a rotating disc electrode atomic emission spectrometer, which can directly inject samples to detect the element content of various wear metals, pollutants and additives in liquid samples such as lubricating oil, hydraulic oil and fuel oil. A single injection can complete multi-element analysis in 2 minutes. The instrument operates without auxiliary gas and cooling water, and can be operated on warships or in the field, with a strong all-weather working capability.

Technical Principle

◆ Oil analysis spectrometers are composed of three main parts: 1) excitation system, 2) optical system, and 3) readout system.

◆ The excitation system comprises a rod electrode, a disc electrode and a light source. One end of the rod electrode is processed into a cone. The disc electrode must have a certain roughness, and all of them are made of high purity graphite. During the excitation process, the disc electrode rotates continuously to bring the oil to the opposite electrode. A high voltage is generated between the electrodes to form an arc discharge, which causes the oil on the disc electrode to burn and each element in the sample to emit a characteristic spectrum.

◆ The intensity of characteristic spectrum line of each element is proportional to its concentration, and the content of each element can be obtained by comparing with the standard curve.



Application Significance

◆ Oil monitoring: equipment wear, oil pollution, oil aging.

◆ The EU spends between £85 billion and £110 billion a year on repairs.

◆ The annual cost of repairs in the United States is about $300 billion to $500 billion.

◆ Maintenance is a huge expenditure in the cost of industrial production, and wear and tear in China causes a loss of 950 billion yuan every year.

◆ Wear, pollution and corrosion are several failure forms of equipment, among which wear failure accounts for 60% to 80%. Oil analysis technology can be used to monitor equipment performance changes and analyze oil abrasive particles, and the information of mechanical lubrication and wear state can be obtained, so that the running state of mechanical equipment can be evaluated and predicted, and then the cause and form of failure can be determined.

◆ Oil analysis technology is or has become one of the indispensable methods of mechanical equipment condition monitoring and fault diagnosis, occupies an important position.

◆ Oil spectral analysis is an effective and mature oil monitoring technology, especially the modern special spectrometer has the characteristics of high degree of automation, fast analysis speed, accurate quantitative and multi-element analysis, so it is widely used.
