Embodiment
[0065] see Figure 8-Figure 10 , the pump casing A and the pump casing B are installed at both ends of the pipeline. There are two in the present invention, and the reference signs are C and D. The main pump support device C and the main pump support device D are installed on the steel structure platform. The main pump on the pump casing plays a supporting role. When testing the main pump A', the main pump supporting device C is fixed, and the relevant limit mechanism of the main pump supporting device D is loosened, so that it can freely expand and rotate at a small angle when the temperature of the pipeline system rises; when testing the main pump B' , the main pump support device D is fixed, and the relevant limit mechanism of the main pump support device C is loosened, so that it can expand freely and rotate at a small angle.
