Abstract
The invention is applicable to the technical field of workpiece detection, and provides workpiece internal structure detection equipment, which comprises a first mass flow meter used for detecting the mass flow of liquid flowing into a workpiece working chamber; a second mass flow meter which is used for detecting the mass flow of the liquid flowing out of the workpiece working chamber; a pressure stabilizing device which is used for inputting liquid with constant pressure into the first mass flow meter; and a differential pressure gauge which is used for detecting the differential pressure between the communication part of the first mass flow meter and the working chamber and the communication part of the second mass flow meter and the working chamber. Compared with the prior art, the change of the mass flow of the liquid flowing through the workpiece is detected by taking the mass of the liquid as the reference under the condition that the pressure difference between the inlet and the outlet of the working chamber is stable, measurement interference items are reduced, and the detection result is more accurate; and secondly, the pressure stabilizing device is arranged, and liquid with constant pressure is outputted through the pressure stabilizing device so that the inlet and outlet pressure difference of the working chamber can be kept stable, and the measurement error is smaller.
Description
Technical field[0001]The invention belongs to the field of workpiece detection, and more particularly to a workpiece internal structural detection device.Background technique[0002]After the workpiece is completed, it needs to be detected inside, and it is determined whether there is internal defect. More than non-destructive detection is currently non-destructive testing, that is, in the premise of not damaged or does not affect the performance of the detected object, the internal structure of the material is abnormal or the heat, sound, and Changes of light, electricity, magnet, etc., by means of physical or chemical methods, with modern technology and equipment equipment, structures, properties, state, and defects of the test piece, nature, state, and defects, , Size, distribution, and changes in inspection and testing thereof.[0003]Take the workpiece in the interior of the chamber as an example, the workpiece can be judged by the workpiece in the working chamber of the workpiece,...
