It is added here that, due to the irregular shape of the pump casing 50, when the first pressure sensors on both sides of the pump casing 50 respectively monitor the pressures, there may be a case where the values of the changes on both sides are inconsistent, that is, the distance between the first limiting plates 720 on both sides and the pump casing 50 is different, and the width of the detection surface of the pump casing 50 is different with respect to the rotation center thereof; however, since the angle of the X-rays is adjusted around the center of the radiation source 310, the radii of the rays projected to both sides of the center of rotation of the pump housing 50 are always equal. Therefore, when the distance between the first limiting plates 720 on both sides and the pump case 50 is increased, that is, the width of the detection surface of the pump case 50 is reduced with respect to both sides of the rotation center, the third linear driving member 330 should be regulated according to the smaller reduction thereof; when the distance between the first limiting plates 720 on both sides and the pump case 50 is reduced, that is, the width of the detection surface of the pump case 50 with respect to both sides of the rotation center is increased, the third linear driving member 330 should be regulated according to the larger increase amount thereof. Thereby, the X-ray can always cover one side of the detection surface of the pump shell 50, which is wider than the rotation center, the whole coverage of the X-ray on the detection surface of the pump shell 50 is ensured, and the detection comprehensiveness is ensured.
