This invention relates to a turbine direct-drive seal test device and method for liquid rocket engines. The turbine direct-drive seal test device for liquid rocket engines includes a housing, a connecting shaft, a radial turbine, an auxiliary impeller, and a test seal. The connecting shaft is coaxially mounted inside the housing, and a sealing ring cover is fixed inside the housing. The sealing ring cover is sleeved on the connecting shaft and rotates and seals with the connecting shaft through the seal. The auxiliary impeller is coaxially fixed on the connecting shaft and arranged adjacent to the sealing ring cover, with a flow clearance reserved between the auxiliary impeller and the sealing ring cover. The stationary ring of the test seal is fixed on the inner wall of the housing, and the dynamic ring of the test seal is fixed on the connecting shaft. The connecting shaft is rotatably connected to the inner wall of the housing through a bearing. Both the bearing and the auxiliary impeller are located in the medium cavity. The housing has a working medium inlet and a working medium outlet. The housing also has a driving medium inlet and a driving medium outlet. One end of the connecting shaft extends into the driving cavity and is coaxially connected to the radial turbine.

The present application belongs to the technical field of tool setting and aligning device, and particularly relates to an adjustable auxiliary tool setting and aligning device. The present application comprises a base, the top surface of the base is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a support through a sliding block, the side surface of the support is connected with a jacking mechanism through an angle adjusting assembly; the side surface of the support is provided with a locking component; the outer wall of the side surface of the support is rotatably connected with a pedal through a rotating shaft; the angle adjusting assembly comprises a mounting seat rotatably connected with the side surface of the support, an adjusting ring rotatably connected with the outer wall of the side surface of the support, a limiting hole provided on the outer wall of the side surface of the support, and a limiting rod inserted into the inner wall of the limiting hole. The present application is convenient to operate, saves time and labor, and does not need to be frequently disassembled and adjusted. After adjustment, the jacking mechanism has good stability, solves the problem that the working stroke of the jacking mechanism is long due to the long distance from the workpiece, and auxiliary improves the working efficiency of setting and aligning.
