Description
Technical field
The present invention relates to a kind of the cannot-harm-detection device, more particularly to a kind of energy-saving eddy current inspection magnetic saturation device.
Background technology
Existing eddy current inspection magnetic saturation device, to save copper wire material, generally after the number of ampere turns of certain coil is designed,
The intensity of magnetization required for detection object is reached using coil outer diameter as small as possible.Consider from technique, if magnetizing coil is most
Amount is long, copper consumption is reduced, and copper resistance declines, and power consumption is also reduced.But that thus brings steel pipe/rod can not visit blind area increase, especially
For high speed detection production line, situation is more serious.In order to solve this problem, be typically only capable to select the ratio of width to height appropriate around
Group, thereby results in unnecessary copper loss and power consumption.Usual magnetic saturation device guide pin bushing is processed by same permeability magnetic material, so,
To reduce the end blind area of pipe/rod eddy current inspection, it is necessary to increase exciting current as far as possible（Generally direct current）.
The content of the invention
It is an object of the invention to overcome the deficiency of prior art to be filled there is provided a kind of energy-saving eddy current inspection with magnetic saturation
Put, using the method for changing guide pin bushing tube material, the magnetic circuit based on general magnetic saturation device has the spy of larger surplus in guide pin bushing tube portion
Point, is made new guide thimble using two kinds of different materials, in the case where not increasing exciting current, both ensure that the intensity of magnetization,
End check frequency is reduced again, improves detection efficiency.
The technical solution adopted for the present invention to solve the technical problems is：A kind of energy-saving eddy current inspection is filled with magnetic saturation
Put, including two guide thimbles, magnetic saturation devices, the magnetic circuit based on magnetic saturation device is adopted the characteristics of guide pin bushing tube portion has larger surplus
New guide thimble is made with two kinds of different materials, it is characterised in that：The guide thimble is two kinds of non-magnet material and permeability magnetic material
The fixed composition of pipe docking of material；The non-magnet material part of described two guide thimbles is outwardly, permeability magnetic material part distinguishes inwardly
Insertion is fixed in the central through hole at magnetic saturation device two ends, and is inserted in two saturation coil windings on both sides in magnetic saturation device
In heart through hole, also there is the magnetic conduction of guide thimble the non-magnet material part of existing guide thimble in saturation coil winding central through hole
Material part.
In detection process, examined workpiece is pierced into out of one side of magnetic saturation device guide thimble, then through in magnetic saturation device
Eddy current probe, finally passed again out of another side guide thimble.Because the magnetic circuit of magnetic saturation device has in guide pin bushing tube portion
Larger surplus, the guide thimble that the present invention is designed, on the premise of intensity of magnetization requirement is ensured, its exciting current is significantly less than commonly
A kind of permeability magnetic material process guide thimble, greatly reduce electric energy consumption；While the magnetic conduction material for the guide thimble that the present invention is designed
It is short that material part processes guide thimble than a kind of common permeability magnetic material, end blind area size is reduced, thus in guarantee end
On the premise of blind area is required, detection efficiency is substantially increased.
The beneficial effects of the invention are as follows a kind of energy-saving eddy current inspection magnetic saturation device, using change guide pin bushing tube material
Method, the magnetic circuit based on general magnetic saturation device is the characteristics of guide pin bushing tube portion has larger surplus, using non-magnetic and magnetic conduction two
Plant different materials and new guide thimble is made, in the case where not increasing exciting current, both ensure that the intensity of magnetization, end is reduced again
Portion's check frequency, improves detection efficiency.
The present invention is described in further detail with reference to embodiments, but a kind of energy-saving eddy current inspection of the present invention is used
Magnetic saturation device is not limited to embodiment.
