Vehicle and ship lubricating oil real time detection method and its device

Abstract

The present invention relates to a real-time detection method of lubricating oil for vehicle and ship and its detection equipment. It is characterized by that a capacitance transducer can be placed into the lubricating oil for vehicle and ship, two electrodes of the capacitance transducer are respectively connected with current meter or capacity meter and varying-voltage frequency converter, and a voltage meter is parallel-connected between two electodes of the capacitance transducer, and the change of voltage and frequency of the varying-voltage frequency converter is controlled by a control device. Said conrol device can make the varying-voltage frequency converter voltage or frequency produce change to measure changed values of current, voltage or capacitance to obtain additive consumption.

Description

technical field [0001] A method and device for real-time detection of lubricating oil for vehicles and ships, belonging to the field of electrical measurement. Background technique [0002] Generally, machines and power devices need to use a large amount of lubricating oil to reduce friction, wear and improve work efficiency. However, as the working time of the machine or power device increases, the lubricating oil will gradually lose its original performance. The effect is gradually lost, and continuing to use lubricating oil that has lost its lubricating effect will seriously affect the life of the machine and reduce work efficiency. However, during the operation of the machine or power unit, it is impossible to know the use status of the lubricating oil in time. Some methods of real-time detection of lubricating oil are quite complicated and require the use of a variety of precision instruments, which is not only time-consuming, but also expensive. F...

[0002] Generally, machines and power devices need to use a large amount of lubricating oil to reduce friction, wear and improve work efficiency. However, as the working time of the machine or power device increases, the lubricating oil will gradually lose its original performance. The effect is gradually lost, and continuing to use lubricating oil that has lost its lubricating effect will seriously affect the life of the machine and reduce work efficiency. However, during the operation of the machine or power unit, it is impossible to know the use status of the lubricating oil in time. Some methods of real-time detection of lubricating oil are quite complicated and require the use of a variety of precision instruments, which is not only time-consuming, but also expensive. For example, in the UK, an oil analysis costs 100 pounds, so the method of regularly replacing lubricating oil is usually adopted. Prevents lubricant failure from damaging machinery and power units
