[0003] High-pressure drainage pump can drive pump shaft by motor or other power source, drive impeller high-speed rotation. The blade on the impeller pushes liquid rotation, makes liquid obtain centrifugal force or axial thrust. Under the action of centrifugal force or axial thrust, liquid is thrown to the edge of impeller from the center of impeller, speed and pressure increase. Then, liquid enters the volute or guide vane part of pump shell, speed gradually reduces, part of kinetic energy is converted into pressure energy, finally is discharged from the outlet of pump with higher pressure, realizes the purpose of drainage.
