Problems solved by technology

[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

Embodiment Construction

[0009] Because the additives contained in the lubricating oil often have a polar bond, and it is usually negative polarity; the lubricating oil will be ionized after oxidation, and after complex chemical reactions, there will be various ions in the lubricating oil. These ions are all charged and can be Detected by various electrical measuring devices, the present invention uses the capacitance method to measure these ions, and can detect the reduction of additives in lubricating oil and the severity of lubricating oil oxidation after simple data processing;

[0010] Please refer to the attached figure 1 In the circuit block diagram of the present invention, a capacitive sensor is placed in the lubricating oil for vehicles and ships, and the two electrodes of the capacitive sensor are respectively connected with an ammeter or a capacitive meter and a variable frequency transformer, and a voltmeter and a variable voltage frequency converter are connected in parallel at the two po...

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.
