Multi-channel mixing acceleration jet pump

The invention discloses a multi-channel mixing acceleration jet pump, and belongs to the technical field of jet pumps. The first partition plate and the second partition plate are fixedly connected with the inner wall of the outer shell and divide the outer shell into a high-pressure fluid inlet area, a suction mixing area and an outlet mixing area; the inner shell, the outer shell, the first partition plate and the second partition plate form a suction cavity; a second through hole is formed in the second partition plate; the high-pressure fluid inlet pipes are fixedly connected with the first partition plate and extend into the first suction chamber and the suction cavity; the low-pressure fluid inlet pipe is arranged on the outer shell and communicated with the suction cavity; the low-pressure fluid inlet main pipe is arranged on the outer shell and communicated with the first suction chamber; the fluid outlet pipe is arranged at the end, away from the high-pressure fluid inlet pipe, of the outer shell, an
