Abstract
The invention discloses a three-hole alternating-current test ring comprising a center copper rod, a steel ring sleeved on the center copper rod, and an annular liner which is sleeved on the center copper rod and is arranged inside the steel ring in a penetrating manner, wherein the annular liner is made of an insulating material; three holes with the axes parallel to the axes of the center copper rod are formed on the end face of the steel ring; and the distances of the three holes and the outer lateral face of the steel ring are sequentially increased. According to the three-hole alternating-current test ring disclosed by the invention, the three holes with the axes parallel to the axes of the center copper rod are arranged on the end face of the steel ring, and the distances between the three holes and the outer lateral face of the steel ring are sequentially increased, so that the sensitivity of the three-hole alternating-current test ring is improved.
Description
Technical field
The present invention relates to the magnetic inspection field, particularly a kind of three holes exchange test ring.
?
Background technology
Magnetic particle inspection apparatus, magnetic, magnetic flaw detection ink need its combination property (system sensitivity) is tested after producing, be the magnetic combination property of alternating current or individual event half-wave rectification electricity for the checking magnetization current, it is high that existing three holes exchange the test ring insufficient sensitivity.
?
Summary of the invention
The purpose of this invention is to provide a kind of three highly sensitive holes and exchange test ring.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of three holes exchange test ring, it comprises the center copper rod, be set in steel loop on the copper rod of center, be set on the copper rod of center and be located in ring liner in steel loop, described ring liner is made by insulating material, offer the hole that three axis parallel with the axis of center copper rod on the end face of described steel loop, the distance of the lateral surface of three described pitch-row steel loops increases progressively successively.
Described steel loop is the steel forgings of annealing in process.
Described ring liner is made by pnenolic aldehyde bakelite.
The distance of the lateral surface of three described pitch-row steel loops is followed successively by 1mm, 1.5mm, 2mm.
Beneficial effect of the present invention is: the present invention offers the hole that three axis parallel with the axis of center copper rod on the end face of steel loop, the distance of the lateral surface of three described pitch-row steel loops increases progressively successively, has improved the sensitivity of three holes interchange test rings.
