To achieve the above object, the present invention provides following technical scheme：A kind of Strong self priming pump, including the pump housing, the pump
Be provided with blade wheel chamber in vivo, be provided with receded disk impeller in the blade wheel chamber, be provided with the pump housing feed pathway, row's gas-liquid channel and
Pump chamber, the feed pathway are connected with blade wheel chamber, and main shaft, one end of the receded disk impeller and main shaft are provided with the pump housing
It is connected, the outer wall of the blade wheel chamber is provided with several exhaust fluid apertures, what the exhaust fluid apertures typed it out receded disk impeller
Dispersion of flow is in pump chamber, being provided with tooth-like impeller, the air-flow expansion that the exhaust fluid apertures types it out tooth-like impeller in the pump chamber
In the row's of being scattered to gas-liquid channel, the main shaft is provided with spline wheel, is connected between the tooth-like impeller and main shaft by spline wheel,
The spline wheel is provided with controlled valve with main shaft by key connection, the outer wall of the spline wheel.
Preferably, annular groove, the controlled valve are along the circumferential direction provided with the spline wheel outer wall
Lower end be arranged in annular groove.
Preferably, the main shaft is provided with dust ring.
Preferably, the port of the feed pathway is provided with filter screen.
Preferably, the controlled valve is provided with balanced handle.
Beneficial effect using above technical scheme is：The Strong self priming pump of structure of the present invention, tooth-like impeller pass through spline wheel
It is connected with main shaft, spline wheel, by key connection, when pump housing starting switch is closed, the rotation of motor driven main shaft, is spent with main shaft
Key wheel is with main axis, and then tooth-like impeller rotates with spline wheel, and tooth-like impeller is started working, and pump intracavity gas are through row
Gas-liquid hole is from the outlet discharge of row's gas-liquid channel, and the medium that feed pathway is conveyed is by receded disk impeller by being vented fluid apertures inflow
Into pump chamber, with the reduction of pump intracavity gas, the medium of feed pathway conveying gradually increases, until whole pump chamber is full of, when
After pressure in pump chamber reaches to a certain degree, controlled valve under the driving of hydraulic pressure, move forward, so promote spline wheel along
Side's forward movement of main shaft so that spline wheel separates with tooth-like impeller, and tooth-like impeller stops operating, and then reduces power of motor
Loss, save the energy.
