Problems solved by technology
[0004] At present, the main methods of particle detection are spectral analysis, scanning electron microscopy and other methods. These methods can only be used for offline detection and cannot realize online detection.
There are wear particle counters for online detection in foreign countries, but this kind of equipment is generally expensive. Based on the current situation in our country, it is difficult to popularize it in small and medium-sized enterprises.

Embodiment Construction
[0010] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.
[0011] Such as figure 1 As shown, the present invention is a device for on-line detection of metal particles in oil, comprising a ceramic tube 4, on which a first coil 1, a second coil 2 and a third coil 3 are sequentially wound, and the first coil 1 It is in reverse series with the third coil 3, the first coil 1 and the third coil 3 are both connected to the AC current source 5, the second coil 2 is located in the center between the first coil 1 and the third coil 3, and the second coil 2 Connect to the processor.
[0012] Principle of the present invention is:
[0013] The first coil 1 and the third coil 3 are driven by the same AC current source 5, and at the same time, they are reversely connected in series, and the directions of the generated magnetic fields are opposite. Therefore, at the central position of the two, the magnetic fields c...

The second coil is located in the central position between the first coil and the third coil. The second coil is connected to a processor. The device realizes on-line detection of metal particles in oil, produces an accurate detection result, utilizes the parts having cheap prices and has a low cost and high efficiency.
Description
[0001] technical field [0002] The invention relates to the field of detection of metal particles in liquid, in particular to a device for on-line detection of metal particles in oil. Background technique [0003] In mechanical equipment, various engine oils are often used. There are some metal particles in the oil, which will cause great wear and tear damage to the mechanical equipment. Therefore, it is necessary to detect these oils containing metal particles. If there are large particles of metal , you should stop the oil supply and replace the oil. [0004] At present, the main methods of particle detection are spectral analysis, scanning electron microscopy and other methods. These methods can only be used for offline detection and cannot realize online detection. There are wear particle counters for online detection abroad, but this kind of equipment is generally expensive. Based on the current situation in our country, it is difficult to popularize and use it in sma...
