Discharging, fluid obtains kinetic energy and static energy in the process.Simultaneously the most also can be because of suction air when centrifugal pump work, and to centrifugal pump
Blade produces serious cavitation effect, centrifugal blade causes damage greatly, motor can cause time serious air sinuses effect,
Burn out motor.For this, we devise a kind of Novel gas-tight erosion formula centrifugal pump, can solve centrifugal pump and produce blade at work
Raw cavitation erosion problem and the air sinuses phenomenon that motor is produced.
Utility model content
The purpose of this utility model seeks to solve above-mentioned technical problem, it is provided that a kind of cavitation-preventive formula centrifugal pump, original
One section of water inlet pipe is installed in the water inlet of centrifugal pump, reduces the centrifugal pump suction to air, thus solves centrifugal pump at work
Problem that blade generation is cavitated and the air sinuses phenomenon that motor is produced.
The technical solution adopted in the utility model is as follows:
A kind of cavitation-preventive formula centrifugal pump, including centrifugal pump, it is characterised in that also include water-retention pipeline section, water suction pipeline section and piston
Draw water pipeline section, and described centrifugal pump is connected with water-retention pipeline section by water pipe, one end of described water suction pipeline section and water-retention pipeline section phase
Even, the other end of water suction pipeline section is connected with water storage device, and the side of the described water-retention pipeline section pipeline section that draws water with piston is connected, piston
Draw water one end of pipeline section is connected with motor.
Wherein, described water-retention pipeline section includes water pipe and one-way plug one, is provided with unidirectional at the upper and lower opening of described water pipe
Plug.
Wherein, being shaped as of described one-way plug one is T-shaped.
Wherein, the described piston pipeline section that draws water includes transverse tube, connecting rod and piston, one end of described connecting rod with on motor
Runner is connected, and the other end of connecting rod is connected with piston, described piston and transverse tube contact internal walls.

Detailed description of the invention
With embodiment, this utility model is described further 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, water suction pipeline section 7 and work
Filling in the pipeline section that draws water, centrifugal pump 8 is connected with water-retention pipeline section 5 by water pipe, and one end of water suction pipeline section 7 is connected with water-retention pipeline section 5, water suction
The other end of pipeline section 7 is connected with water storage device 10, and the side of water-retention pipeline section 5 pipeline section that draws water with piston is connected, and piston draws water pipeline section
One end be connected with motor 1.Water-retention pipeline section 5 includes water pipe and one-way plug one 6, is equipped with one-way plug one 6 at the upper and lower opening of water pipe,
Being shaped as of one-way plug one 6 is T-shaped.The bottom of water suction pipeline section 7 connects water storage device 10, for passing through to inhale by the water in water storage device 10
Water pipe sucks in water-retention pipeline section 5.The piston pipeline section that draws water includes transverse tube 9, connecting rod 3 and piston 4, one end of connecting rod 3 with on motor 1
Runner 2 is connected, and the other end of connecting rod 3 is connected with piston 4, piston 4 and transverse tube 9 contact internal walls.
Wherein, the water pipe caliber of water-retention pipeline section 5 is more than the suction hose caliber of water suction pipeline section 7；The water pipe of water-retention pipeline section 5
Caliber draws water transverse tube 9 caliber of pipeline section more than piston.
The operational approach of this utility model a kind of cavitation-preventive formula centrifugal pump is: before starting centrifugal pump 8, open motor 1,
Motor 1 drives runner 2 to rotate, and the connecting rod 3 on runner 2 drives piston 4 to move back and forth, and piston 4 makes piston to motor 1 one end motion
Drinking-water pipe intrasegmental part produces negative pressure, and the one-way stopper 6 of water-retention pipeline section 5 is opened, and water is inhaled into via water suction pipeline section 7 from water storage device 10
Water-retention pipeline section 5, piston 4 is to water-retention pipeline section 5 one end motion, and now one-way stopper 6 is closed, and water is left in water-retention pipeline section 5.When water is noted
When no longer leaving air in full water-retention pipeline section 5 and water-retention pipeline section 5, then open centrifugal pump 8, allow centrifugal pump 8 inhale in water-retention pipeline section 5
Water, operates the most repeatedly, it is possible to reduce the centrifugal pump 8 suction to air, and blade and motor to centrifugal pump 8 play protection and make
With.
