Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is equipped with the pump housing 1, and 1 two sides of the pump housing are separately connected 2 He of water inlet pipe
Outlet pipe 3 is equipped with motor 4 above the pump housing 1, and 4 output end of motor is equipped with the pump shaft 5 protruded into inside the pump housing 1, and 5 lower end of pump shaft is fixed
There is impeller, impeller includes inner impeller 6 and out rotor 7, and impeller is fixed by inner impeller 6 and pump shaft 5, and out rotor 7 is set to inner impeller 6
Outside, out rotor 7 is fixed by bolt and the pump housing 1, and impeller channel 11 is formed between inner impeller 6 and out rotor 7, and motor 4 is logical
Cross the rotation of 5 impeller of pump shaft.
It is equipped with cone-shaped cavity 8 above 1 internal impeller of the pump housing, is divided 1 top motor 4 of the pump housing with impeller using cone-shaped cavity 8
From effectively avoiding 1 internal liquid of the pump housing from entering motor 4, cone-shaped cavity 8 and 5 junction of pump shaft are equipped with bearing 9, are used to support
Pump shaft 5 rotates, and water sealing device 10 is equipped with above impeller, carries out axial seal to impeller, 8 bottom end of cone-shaped cavity passes through cone copper
Set 14 is fixed on the periphery of impeller Yu water sealing device 10；8 bottom end periphery of cone-shaped cavity, which is equipped with, divides water jacket 12, to gas and liquid
It is separated.
It is equipped with check-valves 13 at water inlet pipe 2, makes liquid one-way flowing at water inlet pipe 2, avoids enter into the liquid inside the pump housing 1
There is backflow phenomenon in body.
Automatic exhaust steam valve is equipped at outlet pipe 3, automatic exhaust steam valve includes valve body 15, and 15 bottom end of valve body is connected to outlet pipe 3,
Ball valve 16 is equipped with inside valve body 15,15 top of valve body is equipped with elbow 17, and 17 other end of elbow is equipped with exhaust outlet 18, inside valve body 15
It is equipped with boss 19 at elbow 17, spring 20 is fixed with below boss 19, ball valve 15 is set to 20 lower section of spring, before the pump housing 1 starts, ball
Valve 15 is being self-possessed under the spring-force driven dual with spring 20 positioned at 15 inner bottom of valve body, and by 15 bottom end closure of valve body, the pump housing 1 starts
When, impeller rotation brings gas at outlet pipe 3 into, and under gas pressure effect, ball valve 16 is pushed, and 15 bottom end of valve body is opened,
Gas enters inside valve body 15 to be discharged through exhaust outlet 18, and ball valve 16 is under the action of 20 spring force of gas pressure and spring in valve body
Balance is kept in 15, it can continuous exhaust pneumatic wallop；It is hydraulically full at outlet pipe 3 when gas is drained, as shown in figure 5, ball valve 16 is in liquid
15 top of valve body is moved under the pushed at high pressure of body, automatic exhaust steam valve is closed at this time, realizes automatic exhaust.
In use, access needs the water source conveyed at water inlet pipe 2, motor 4 drives the rotation of 5 impeller of pump shaft, impeller
Liquid will be entered from water inlet pipe 2 and air sucks together, and be thoroughly mixed in impeller channel 11, under the influence of centrifugal force,
Liquid entrainment gas certain thickness white foam band and high speed rotation pendular ring are formed in the outer rim of impeller, with impeller
Rotation, gas and liquid mixture is flowed to outlet pipe 3, and since flow velocity reduces suddenly at outlet pipe 3, lighter gas is from gas-liquid mixed
It is separated in liquid, gas is discharged through automatic exhaust steam valve, and liquid reflux is again introduced into impeller, mixes again in impeller channel 11
It closes, and under the effect of high-speed rotating impeller, and flows to impeller outer edge, as this process goes on again and again, inhale
The air entered in pipeline is constantly reduced, and until exhausting gas, completes self-priming process.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
