Multi-spindle pump core capable of rotating by means of star gear principle

Abstract

The invention discloses a multi-spindle pump core capable of rotating by means of a star gear principle. The multi-spindle pump core comprises motor connecting shafts, driven shafts, connecting frames, drive gears, blades, fixed ends and driven gears, the blades are obliquely fixed on the cylindrical surfaces of the driven shafts in the same oblique angles, the fixed end is arranged at each of two ends of each driven shaft, the driven gear is arranged at the outer side of each fixed end, the driven gears surround the central lines of the drive gears in one circle in the same angles, the driven gear is engaged to the corresponding drive gear, the motor connecting shaft is arranged at the outer side of the drive gear and connected with the driven shaft extending end through the connecting frame, and the end of the motor connecting shaft is connected with the output shaft of a pump motor through a coupling. By means of the multi-spindle pump core capable of rotating by means of the star gear principle, the shaft with oblique blades can replace the blade in a pump body with large pipe diameter to improve the water pumping effect.

Description

technical field [0001] The invention relates to the field of accessories for pumps, in particular to a multi-rotating shaft pump core that uses the principle of star gears to rotate. [0002] Background technique [0003] The pump core is the core part of the pump. It is installed in the pump body. The blades on it or the shaft with inclined blades rotate to drive the water flow to realize the pumping of water. Because the blades of the shaft with inclined blades are inclined on the shaft Therefore, compared with ordinary blades, the contact area with the liquid is larger, and the pumping effect is better, but because a motor can only drive one shaft to rotate, and the shaft with inclined blades is limited by the strength, the width of the blade should not be too long, so Only suitable for small diameter pump body. [0004] Contents of the invention [0005] In view of the above problems, the present invention is a multi-rotation shaft pump core that utilizes the star g...
