[0062] Working principle: When using this shock-absorbing multi-stage high-efficiency supercharging pipeline pump, the liquid is sent into the inner layer 5 of the shell through the water inlet pipeline 3. Driven by the motor 11, the rotating rod 6 makes the vortex blade 7 rotate to pressurize the liquid in the pump. During the process of the liquid flowing under pressure in the outer layer 1 of the shell and the inner layer 5 of the shell, the limit stabilizing ring 8 at the bottom end of the rotating rod 6 is used to maintain the stability of the rotating rod 6 during rotation.
