(3) beneficial effect
The present invention provides a kind of centrifugal pump auxiliary self-priming apparatus, vacuum pump, ball valve, graded tube and check is applied in combination
Valve realizes centrifugal pump body self-priming, and vacuum pump works as pump shaft rotates, and by high-pressure air pipe to air in centrifugal pump body into
Row vacuumizes, so that centrifugal pump body water inlet forms negative pressure and is self-introduced into water, graded tube real time reaction liquid level, works as quarter
Intraluminal fluid position is spent more than after specific scale, and closing control valve disconnects vacuum pump pumping, and centrifugal pump body starts to work normally；This
Device is easy to operate, avoids the filling liquid for being using forefathers.

Embodiment in the present invention, those of ordinary skill in the art are obtained all other without making creative work
Embodiment, belongs to the scope of protection of the invention.
Referring to attached drawing, a kind of centrifugal pump auxiliary self-priming apparatus, including centrifugal pump body 1, vacuum pump 4, graded tube 8, control
Valve 10 and non-return valve 2；Non-return valve 2 is arranged on the water outlet of centrifugal pump body 1, and vacuum pump 4 passes through belt 6 and centrifugal pump body 1
Pump shaft 5 is connected；The water inlet of 8 vertical connection centrifugal pump body 1 of graded tube；8 top of graded tube passes through high-pressure air pipe 7 and vacuum pump 4
Air entry be connected, junction is provided with control valve 10；The exhaust outlet 12 of vacuum pump 4 is in communication with the outside；Set on graded tube 8
Specific scale is equipped with, specific scale corresponds to scale when water is full of in 1 pump chamber of centrifugal pump body.
Wherein, the machine sealing position of centrifugal pump body 1 is also connected with organic envelope lubrication assembly 11, lubrication during for machine Feng Ganzhuan and cold
But.
Wherein, 8 tip height of graded tube is higher than centrifugal pump body 1, avoids after water is filled in centrifugal pump body 1, water directly from
