Application of Baxter particle counter in hydraulic oil and lubricating oil pollution detection
During the use of hydraulic and lubrication systems, particles generated by external environment and internal friction will cause the oil to become dirty, and dirty oil will cause component wear, blockage, damage and other failures, seriously affecting the effective operation rate of the equipment. Therefore, effective detection of the particle content in the oil and timely replacement of contaminated hydraulic oil or lubricating oil are effective methods to ensure the safe operation of mechanical equipment.
In order to quantitatively detect the pollution degree of oil, it is necessary to classify the pollution degree according to the content of solid particles in oil and determine the detection instrument and method. At present, the industry generally divides the pollution level of oil products according to the international standard ISO4406 or the American Aerospace Society standard NAS 1638, and uses the photoresist particle counter as the oil pollution detection instrument.
Baxter particle counter
The BettersizeC400 optical particle counting analyzer (referred to as Baxter particle counter) developed by Dandong Baxter has the ability to detect the size and number of solid particles in different oils. It uses the international advanced photoresist and Angle scattering technology combined with high-sensitivity detector and high-precision signal acquisition and transmission system, can accurately analyze the particle size, number and particle size distribution between 0.5-400μm.
Test principle of particle counter
The test principle of the particle counter is that when the particles pass through the capillary measurement area one by one through the pump, when the laser illuminates the particles, because the particles are blocked and scattered, the photoresistance and scattered signals proportional to the size of the particles are generated, and the optical signals are received by the sensor and transmitted to the computer, and then the signals are processed by special analysis software. The information of particle size, quantity and particle size distribution is obtained. Particle counter has the characteristics of high sensitivity, accurate results, fast analysis speed, and can analyze samples containing very few particles.
