چکیده
Metal abrasive particle content in lubricating oil is an important index to judge the degree of deterioration of lubricating oil. Established a spiral electrode capacitance sensor by the finite element software ANSYS, the simulation result shows that the sensor is sensitive to the content of metal abrasive particle in lubricating oil, not affect by the metal abrasive particle itself. According to the simulation optimization model to make the real sensor, and designed lubricating oil pollution degree measurement system with the MS3110 capacitance detection circuit and MCU. Experiments show that it can distinguish metal abrasive particle from the change of 0.1 %-0.5 % content, this change can determine the degree of pollution of metal abrasive particle in lubricating oil, provides a simple and feasible method for the oil pollution detection.

متن کاملEffects of used lubricating oil on two mangroves Aegiceras corniculatum and Avicennia marina.
An outdoor experiment was set up to investigate the effects of used lubricating oil (5 L/m2) on Aegiceras corniculatum Blanco. and Avicennia marina (Forsk) Vierh., two salt-excreting mangroves. A. marina was more sensitive to used lubricating oil than A. corniculatum and canopy-oiling resulted in more direct physical damage and stronger lethal effects than base-oiling. When treated with canopy-...
