Oil metal abrasive particles online monitoring system

Abstract

An oil metal abrasive particles online monitoring system comprises sensors, a microprocessor and a circuit; each sensor is a solenoid type inductive transducer, and an oil circuit can pass through the solenoid of the inductive transducer; an excitation AC signal-generator is connected with two excitation coils respectively in two totally same sensors, and two induction coils of the two sensors are connected with a signal amplifier; and the signal amplifier, a RMS-DC converter, an AD converter, the microprocessor and a display are in a sequential connection, and the microprocessor is also connected with a keyboard and an alarm. The monitoring system is reasonable in structure, high in sensitivity of monitoring weak signals outputted by the inductive transducer, good in linearity, good in anti-interference capability, stable and reliable in operation, convenient to operate, good in real-time performance, high in measuring precision, and accurate and reliable in monitoring result. The monitoring system can be used in military and civil fields, be used to monitor and diagnose oil pollutant degree and faults of machinery equipment such as various airplanes, ships, automobiles and the like, and the occurrence of various engine accidents is avoided.

Description

technical field [0001] The invention relates to state monitoring of mechanical equipment, in particular to an oil analysis technology therein, and more specifically to an online monitoring system for oil and metal abrasive particles. Background technique [0002] Equipment wear failure is the most common form of failure. More than 70% of mechanical equipment failures are related to wear. The parameters obtained by monitoring and analyzing the oil can well judge the lubrication and wear state of the equipment. It is a new technology for mechanical equipment condition monitoring that has developed rapidly in the past ten years. Especially in the aspects of engines, gear transmissions, bearing systems, hydraulic systems, etc., this technology has achieved remarkable benefits, so it has been highly valued at home and abroad. . At present, in industrially developed countries, oil analysis technology is becoming or has become one of the indispensable methods for mechanical equipm...
