Abstract
The invention discloses a device for on-line detection of metal particles in oil. The device comprises a ceramic tube. A first coil, a second coil and a third coil are wound on the ceramic tube. The first coil and the third coil are reversely connected in series. The first coil and the third coil are both connected to an AC power supply. 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
Technical field
The present invention relates to metallic particles detection field in liquid, particularly the device of metallic particles in a kind of online detection fluid.
Background technology
In plant equipment, often can use various machine oil, in fluid, have some metallic particles; can cause very large wear damage to plant equipment, therefore will detect the fluid of these containing metal particles, if find that there is bulky grain metal; should fuel cut-off, change fluid.
To particle detection, be mainly to carry out the methods such as spectral analysis, scanning electron microscope at present, these methods can only be done and carry out offline inspection, can not realize online detection.Have abrasive particle counter to carry out detecting online abroad, but this equipment is generally all more expensive, based on China's present situation, is difficult in the universal use of medium-sized and small enterprises.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the device of metallic particles in a kind of online detection fluid, there is feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
The device of metallic particles in a kind of online detection fluid, comprise ceramic pipe 4, on ceramic pipe 4, be wound with successively the first coil 1, the second coil 2 and tertiary coil 3, the first coil 1 and tertiary coil 3 differential concatenations, the first coil 1 and tertiary coil 3 all connect ac current source 5, the second coil 2 is Centromedian position between the first coil 1 and tertiary coil 3, and the second coil 2 connects processor 6.
Compared with prior art, the present invention can detect the metallic particles in fluid online, and testing result is more accurate, and the parts price of device use is all very cheap, has realized the object of low-cost high-efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in Figure 1, the present invention is the device of metallic particles in a kind of online detection fluid, comprise ceramic pipe 4, on ceramic pipe 4, be wound with successively the first coil 1, the second coil 2 and tertiary coil 3, the first coil 1 and tertiary coil 3 differential concatenations, the first coil 1 and tertiary coil 3 all connect ac current source 5, the second coils 2 Centromedian position between the first coil 1 and tertiary coil 3, and the second coil 2 connects processor.
Principle of the present invention is:
The first coil 1 and tertiary coil 3 are driven by same ac current source 5, while differential concatenation again, and the magnetic direction of generation is contrary, and therefore, in the two central position, cancel out each other in magnetic field, and middle position is zero magnetic field.The second coil 2 is positioned at zero place, magnetic field, when in fluid when having larger metallic particles, can cause disturbance of magnetic field, the second coil 2 produces induction electromotive force, and this electromotive force signal is input to processor 6, can analyze its particle size.
Claims (1)
1. an online device that detects metallic particles in fluid, comprise ceramic pipe (4), it is characterized in that, on ceramic pipe (4), be wound with successively the first coil (1), the second coil (2) and tertiary coil (3), the first coil (1) and tertiary coil (3) differential concatenation, the first coil (1) and tertiary coil (3) all connect ac current source (5), the second coil (2) is positioned at Centromedian position between the first coil (1) and tertiary coil (3), and the second coil (2) connects processor (6).
