Example (b):

referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an intelligence efficient tubing pump, includes driving motor 1 and the pump body 2, driving motor 1's output shaft bottom is connected with pivot 3, pump storehouse 8 has been seted up on the body of the pump body 2, pivot 3 inserts inside pump storehouse 8 of the pump body 2, and pivot 3 is located the inside one end outside of pump storehouse 8 and evenly is provided with blade 4, lateral wall is connected with inlet 5 and liquid outlet 6 respectively about the pump body 2, inlet 5 and liquid outlet 6 all communicate with pump storehouse 8, pump storehouse 8 is the little shape of the big right-hand member of left end, be provided with pressure sensor 7 on the liquid outlet 6, blade 4 includes blade base member 41, the adjustment tank has been seted up on the blade base member 41, the one end that blade base member 41 deviates from pivot 3 is provided with overhanging blade 42, overhanging blade 42 activity is inserted in the adjustment tank.

Preferably, the bottom of the driving motor 1 is fixedly connected with the upper surface of the pump body 2 through a support column.

Preferably, a connecting plate is arranged at one end of the blade base body 41 close to the rotating shaft 3, and the connecting plate is connected with the outer wall of the rotating shaft 3 through a screw.

Preferably, a supporting ball 43 is embedded in a side wall of one end of the overhanging vane 42 facing away from the rotating shaft 3.

Preferably, the inner wall of the pump chamber 8 is uniformly coated with a wear-resistant coating.

The working principle is as follows: when the liquid pump is used, the driving motor 1 drives the blades 4 to rotate through the rotating shaft 3, and the rotating blades 4 pump out liquid in the liquid inlet 5 and output the liquid through the liquid outlet 6.

The pressure sensor 7 detects the hydraulic pressure in the liquid outlet 6, and when the output hydraulic pressure is small, the rotating speed of the driving motor 1 is controlled to be increased (the specific rotating speed control mode is the prior art, and is not described herein any more), and when the output hydraulic pressure is large, the rotating speed of the driving motor 1 is controlled to be decreased.
