Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7The utility model provides a technical solution: a comprehensive test platform for a special boost pump for a large-flow aircraft engine, including a test bench seat 1, a movable plate 2, a threaded rod 3, a fixed rod 4, a support column 5, an adjustment column 6, a test bench 7, a fixing mechanism 8, a fixing frame 9, a connecting rod 10, a spring 11, a positioning rod 12, a positioning groove 13, a fixing splint 14, an auxiliary rod 15, a mounting column 16 and a fixing bolt 17.

[0031] When using the comprehensive test platform for the large flow aircraft engine special boost pump, Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, first, the booster pump to be tested is moved to the middle of the upper end of the test bench 7, and then the fixed clamping plate 14 is moved. The fixed clamping plate 14 is fixedly connected to the upper end of the auxiliary rod 15, and the fixed clamping plate 14 drives the auxiliary rod 15 and the mounting column 16 to slide. At the same time, the fixed clamping plate 14 is set at an equal angle on the upper end of the test bench 7. The booster pump is stably clamped by the fixed clamping plate 14 to improve the stability of the booster pump during the test and detection process. Then, the fixing bolt 17 is rotated, and the fixing bolt 17 is threadedly connected to the auxiliary rod 15. The upper end of the fixing bolt 17 is squeezed on the mounting column 16, which is convenient for limiting the auxiliary rod 15 and the mounting column 16, and limiting the fixing clamping plate 14;

[0032] After the booster pump is fixed, according to the test requirements, such as Figure 3 , Figure 4 and Figure 5 As shown, the threaded rod 3 can be rotated at the upper end of the test bench seat 1, and the threaded rod 3 is threadedly connected with the movable plate 2, thereby driving the movable plate 2 and the fixed rod 4 to slide, so that the fixed rod 4 drives the test bench 7 to move left and right at the upper end of the test bench seat 1, thereby facilitating the corresponding adjustment of the position of the booster pump, without moving the booster pump, and the operation is more labor-saving, and combined with the setting of the fixing mechanism 8, the fixing mechanism 8 includes a fixing frame 9 sleeved on the outside of the support column 5, a connecting rod 10 fixedly connected to the left end of the support column 5, a spring 11 sleeved on the outer surface of the connecting rod 10 and a positioning rod 12 fixedly connected to the upper end of the test bench 7;
