Abstract
This utility model discloses a pressure testing fixture for a sealing component, including a pressure testing bracket. A bearing sleeve is fixedly connected to the inner wall of the pressure testing bracket, and a main shaft is fixedly connected to the inner ring of the bearing sleeve. A support sleeve is fixedly connected to the inner wall of the pressure testing bracket. A hinge seat is fixedly connected to the right end of the pressure testing bracket, and a sealing bushing is fixedly connected to the inner wall of the hinge seat. A shaft is fixedly connected to the inner wall of the sealing bushing, and a mechanical seal outer sleeve is fitted onto the outer surface of the sealing bushing. The left end of the mechanical seal outer sleeve is fixedly connected to the right end of the hinge seat, and a fastening nut is threaded onto the outer surface of the right end of the shaft. This utility model, through the configuration of the pressure testing bracket, bearing sleeve, main shaft, support bearing, sealing bushing, hinge seat, mechanical seal outer sleeve, and fastening nut, allows for tightening and positioning of the shaft by tightening the fastening nut, achieving compressive contact between the shaft and the main shaft, increasing the compressive force between the main shaft and the shaft, and achieving the sealing effect of the sealing component during compression, thus facilitating pressure testing of the sealing component.
