Problems solved by technology

[0004] (1) Effect of high temperature
[0005] ①The lubricating oil is in a high temperature environment for a long time, it will oxidize and fail, and it will turn black and thicken
[0009] (3) Additives and viscosity index improvers fail
[0010] Some lubricating oils have lost performance because the additives in them have failed or been used up
For example, if the anti-wear agent in the lubricating oil is used up, the anti-wear property will decrease
Or because the long chain of the organic molecule of the viscosity index improver is broken, it no longer has the effect of increasing viscosity
[0011] (4) The moisture in the oil exceeds the standard
But at present, the dynamic monitoring of oil condition has not received much attention, and there is no mature online oil condition monitoring system and method

Embodiment

[0040] Take the continuous casting hydraulic station of a steelmaking plant as an example: N 32 Great Wall brand 4632 ester type flame retardant hydraulic oil is used, and the standard kinematic viscosity is 28.8~35.2mm 2 / s, the allowable water content is 0.02%, the allowable impurity content is 0.005%, the allowable working temperature is below 60°C, and the working pressure is 8MPa.

[0041] Set the monitor, sensor and monitoring system according to the above method, and the monitoring results at a certain time are as follows:

Abstract

The invention relates to an oil condition on-line monitoring system of hydraulic oil and lubricating oil, and is characterized in that the system consists of an oil condition detection and sensing system, an environment monitoring system, a data collection and conversion system, an operation procedure, a warning (caution) system and an automatic implementing system; a bypass and an oil storage chamber are arranged on an oil station; each monitoring unit is fixed to monitor an oil viscosity, a micro-moisture content, a temperature, impurity, a pressure and other parameters in real time; an actual measured value is compared with the set value; when the actual measured value excesses an allowed range, the system automatically warns or implements the functions of closing, self-locking, etc.

Description

technical field [0001] The invention relates to the field of mechanical lubrication, in particular to an online monitoring system and method for hydraulic oil and lubricating oil. Background technique [0002] In large-scale operation equipment, hydraulic system and lubrication system are inseparable. Hydraulics is one of the main transmission methods. Hydraulic oil is not only the medium for power transmission, but also lubricates, seals and cools hydraulic components. The main function of lubricating oil is to lubricate and cool the transmission parts, which determines the working efficiency and service life of the equipment. Therefore, the condition of the oil It is very important for the working condition and working performance of the hydraulic system. [0003] Reasons for failure of hydraulic pressure and lubricating oil: [0004] (1) Effect of high temperature [0005] ① Lubricating oil is exposed to high temperature for a long time, it will oxidize and fail, and ...
