A flaw detection device and flaw detection method suitable for pump head body cavity

Abstract

A flaw detection device suitable for the inner cavity of a pump head body, threaded holes are opened on both end surfaces of a copper rod, grooves are opened on the arc surface along the axis direction of the copper rod, a copper tube is embedded in the groove of the copper rod, both ends of the copper tube are fixed to the copper rod by tube clamps and screws, the end of the copper tube is threadedly connected to the copper tube plug, and the other end is threadedly connected to the magnetic suspension control valve, and 180° fan-shaped dense through holes are regularly distributed on the outer surface of the copper tube, and the dense through holes face the outside of the copper rod groove. The device can be placed in the inner cavity of the pump head body for flaw detection. The present invention solves the problems of uneven wetting of the inner cavity, time-consuming and labor-intensive detection process, low efficiency, waste of magnetic suspension, environmental pollution, and insufficient wetting of the edge of the through hole in the original flaw detection process.
