Operation principle of the invention：
Impeller 2 is fastened on the shaft end of pump shaft 18, in pump case 1；Claw type yielding coupling sub-assembly 20 by pump shaft 18 with
Motor shaft is coupled together, and shaft coupling Main Function is for connection to driven shaft and driving shaft and transmitting torque, will be dynamic on motor
Main shaft 18 can be passed to, and yielding coupling 20 can buffer absorbing, compensate larger axial displacement, micro radial displacement
And angular displacement, it is ensured that the steady operation of machine.
Motor transfers kinetic energy to pump shaft 18, so that the rotary work of impeller 2, impeller 2 is driven at a high speed by pump shaft 18
Rotate, the liquid between impeller 2 also must be with rotation.Under the influence of centrifugal force, liquid is thrown to outer rim simultaneously from the center of impeller 2
Energy is obtained, impeller outer edge into pump case component 1 is left with high speed.In pump case component 1, liquid is due to the gradually expansion of runner
And slow down, and part kinetic energy is changed into static energy, discharge line is finally flowed into pressure higher.Liquid is by the center of impeller 2
When flowing to outer rim, certain vacuum is centrally formed in impeller 2, because the pressure of storage tank ullage is more than at liquid inlet
Pressure, liquid just by continuously press-in impeller 2 in, so, as long as impeller 2 is constantly rotated, liquid will constantly be inhaled into and
Discharge；When liquid is discharged, liquid can be shunted by mozzle 36.
