Description

Technical Field

[0001] The invention belongs to the technical field of online oil monitoring, and relates to an online oil monitoring device for oil of a large-scale road maintenance machinery. Background Art

[0002] At present, there are many types of large-scale road maintenance machinery, such as cleaning and screening machines, tamping machines, and grinding machines. The internal systems of large-scale road maintenance machinery include hydraulic systems, transmission systems, and travel systems. The oils used in the internal systems of large-scale road maintenance machinery are different, such as hydraulic oil, gearbox oil, and diesel engine oil. There are many types of oils, and the comprehensive performance requirements of oils are high, and the performance that needs to be monitored is diverse. Online monitoring of oil products has developed rapidly, but due to the constraints of sensors, its accuracy and stability are poor. Due to the different characteristics and structures of different parameter sensors, different sensors installed in different positions on the oil circuit will have different reactions, and even the order and position of the installation of two sensors are different. The data collected by the originally very accurate and intact sensors after being installed in the same oil circuit will produce very large errors.

[0003] In addition, under normal operating conditions, large-scale road maintenance machinery is affected by the working environment and the vibration of various parts is obvious. Secondly, the management of hydraulic oil and gear oil must be sampled and tested regularly, and the oil must be replaced or treated according to the test indicators, which puts high demands on the oil inspection ability and the rationality of the oil change indicators. In addition, there are great difficulties in sampling and testing the oil of large-scale road maintenance machinery, among which the problems of sampling, transportation, and long testing cycle are all related to the inconvenience of the testing equipment.
