Oil liquid monitoring instrument

Abstract

The embodiment of the invention relates to the field of oil liquid measurement and control, in particular to an oil liquid monitoring instrument. The oil liquid monitoring instrument comprises an instrument box having mounting space, a connecting pipe arranged in the mounting space and used for transmitting oil liquid, a first sensor module having a first sensing function, and a second sensor module having a second sensing function different from the first sensing function. The first sensor module can be installed in the installation space at the first position and connected with the connecting pipe so as to form a part of an oil liquid transmission channel of the oil liquid monitoring instrument. The second sensor module can replace the first sensor module, is installed in the mounting space at the first position, and is connected with the connecting pipe. According to the oil liquid monitoring instrument, different sensor modules can be quickly switched in a modularized manner, so that a portable online oil liquid monitor system can be implemented, and the oil liquid monitoring instrument has the advantages of standardization, generalization, light weight, small size, complete functions, quick modularized reloading and low cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of oil measurement and control, in particular to an oil monitor. Background technique [0002] Oil is called the "blood" of industry, and plays an important role in mechanical equipment such as improving power, lubricating, sealing, anti-corrosion, and cooling. According to statistics, more than 70% of the failure of mechanical equipment is caused by wear. In order to reduce wear and prolong the service life of parts, oil lubrication is often used. The state of the oil in the mechanical equipment can directly reflect the wear state of the mechanical equipment, so the monitoring of the oil in the mechanical equipment is particularly important. [0003] For example, the oil monitor of the online oil monitoring system is mainly used to monitor the content of ferromagnetic and non-ferromagnetic abrasive particles in the oil of mechanical equipment, monitor the content of oil pollution ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the existing oil monitor cannot implement a small-sized instrument box to standardize and universally install all oil sensors and oil flow control devices such as pumps and pressure reducing valves; thus, the existing oil The monitor will increase the cost of repeated design and increase the number of materials, and the parts and materials cannot be standardized and common, resulting in idleness, which will lead to an increase in material costs
