On-line monitoring plant for ferromagnetic grains in engine oil

Abstract

The invention discloses an on-line monitoring plant for ferromagnetic grains in engine oil, which is characterized by comprising a sensor unit, an electronic storage and control unit and a display unit, wherein the sensor unit is installed in the oil duct to be tested and adapts to the diameter of the oil duct to be tested; the electronic storage and control unit and the display unit are installed outside the oil duct to be tested; the sensor unit is connected with the electronic storage and control unit through a common cable; the electronic storage and control unit is connected with the display unit through an RS232 or RS422/485 series interface in common industry standard; and the display unit displays the detection values of the ferromagnetic grains in the engine oil in the on-line monitored oil duct. The plant can work in the environment of extreme temperature and vibrations, has the advantages of simple structure, convenient operation and high monitoring and response speed, and can realize prewarning of equipment failures in time. The plant is beneficial to determining the residual life of lubricating oil, optimizing the oil change period and reducing the possibility of accidents. The plant has significant economic value and is of great importance for environmental protection.

Description

technical field [0001] The invention relates to an on-line monitoring device for the wear state of mechanical equipment; in particular, it relates to an on-line monitoring device for ferromagnetic particles of engine oil. The invention belongs to the technical field of on-line monitoring devices for mechanical equipment abrasive particles. Background technique [0002] Abrasion is one of the main factors of failure of mechanical parts. Among the failure modes of machine parts, wear failure mode accounts for more than 70%. The state of abrasive particles implies a large amount of information on the operating state of mechanical equipment, which can reflect the current situation and development trend of equipment wear in a timely manner. At the same time, it is also an important basis for diagnosing equipment failures, predictive maintenance, and improving design of equipment. [0003] The detection of abrasive particles in mechanical equipment oil is generally divided into tw...

Problems solved by technology

At present, my country is still blank in the manufacture of "on-line ferromagnetic wear particle state and lubricating oil monitoring" instruments, and the few similar instruments in the world are still in a state of large size, complex technology, small application range, and high price

In addition, the oil online monitoring technology is complex and difficult to implement. At present, it has not been widely used in the industrial field.
