(1) opening motor, driven by motor runner rotates, and the connecting rod on runner drives reciprocating motion of the pistons；
(2) piston makes piston drinking-water pipe intrasegmental part produce negative pressure, the individual event of water-retention pipeline section to motor one end motion
Plug is opened, and water is inhaled into water-retention pipeline section from water storage device via water suction pipeline section；
(3) piston moves to water-retention pipeline section one end, and now one-way stopper is closed, and water is left in water-retention pipeline section；
(4) when no longer leaving air in water fills water-retention pipeline section and water-retention pipeline section, then open centrifugal pump, allow
Water in centrifugal pumping water pipe section；
(5) step (1) to (4) is repeated.
Compared with prior art, the invention has the beneficial effects as follows: install one in the water inlet of original centrifugal pump
Section water inlet pipe, reduces the centrifugal pump suction to air, thus the blade and motor to centrifugal pump plays protection and make
With, centrifugal pump the cavitation erosion problem at work blade produced and the air sinuses phenomenon that motor is produced can be solved.

Detailed description of the invention
The present invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment
As depicted in figs. 1 and 2, a kind of cavitation-preventive formula centrifugal pump, including centrifugal pump 8, water-retention pipeline section 5, inhale
Water pipe section 7 and piston draw water pipeline section, and centrifugal pump 8 is connected with water-retention pipeline section 5 by water pipe, water suction pipeline section 7
One end be connected with water-retention pipeline section 5, water suction pipeline section 7 the other end be connected with water storage device 10, water-retention pipeline section
The side of 5 pipeline section that draws water with piston is connected, and draw water one end of pipeline section of piston is connected with motor 1.Water-retention pipeline section 5
Including water pipe and one-way plug one 6, at the upper and lower opening of water pipe, it is equipped with one-way plug one 6, being shaped as of one-way plug one 6
T-shaped.The bottom of water suction pipeline section 7 connects water storage device 10, for the water in water storage device 10 is passed through water suction
