Abstract

The invention provides an online collecting and monitoring device for diesel engine lubricating oil. The online collecting and monitoring device comprises a sampling tube, an oil outlet tube, a residual gas treater, a micro pump, a sampling circulating valve, a micro radiator, a heat exchange switching valve, an oil sample collecting switching valve, a heat exchange temperature sensor, a sample temperature sensor, an oil quality sensor, a particle content sensor, a sampling bottle, a liquid level sensor, a signal processing device and a displayer. One end of the sampling tube is connected with a diesel engine oil return tube, one end of the oil outlet tube is connected with an oil tank of a diesel engine, and then a new lubricating oil collecting and monitoring bypass is formed on the basis of an original circulating loop of the diesel engine and the oil tank. The online collecting and monitoring device can complete collecting of lubricating oil of any type of diesel engines and monitoring of the frictional wear state of the diesel engines online in real time, the accuracy of collected oil samples and monitoring data is guaranteed, major failures of the diesel engines can be avoided in time, and property loss can be reduced.

Description

technical field [0001] The invention belongs to the technical field of engine running state monitoring, and in particular relates to an online collection and monitoring device for lubricating oil of a diesel engine. Background technique [0002] Lubricating oil is the "blood" of mechanical equipment, and plays an important role in sealing, lubricating, reducing wear, cooling, cleaning, shock absorption and anti-corrosion in mechanical equipment. Lubricating oil analysis is one of the important means to realize the fault diagnosis of mechanical equipment. It can obtain information about the wear state of parts, machine working conditions and oil pollution degree. Friction and wear are the main reasons that affect the reliability and service life of mechanical equipment. All kinds of running machinery are kinematic pairs composed of various friction pairs. Friction and wear will inevitably occur during operation, which is the failure of parts and main modes of failure. Abras...
