Discharge pipe and outlet connection 21: according to Fig. 1-5, being attached by working principle first, then by the water pump
It is placed in waters, moisture enters drawing water in chamber 3 on the inside of the pump housing 1 by the water-inlet horn 2 of 1 lower section of the pump housing at this time, then starts
The water pump, the rotor 4 in the pump housing 1 starts to be rotated at this time, while rotor 4 is rotated,
Rotor 4 starts that the first impeller 5 is driven to be rotated, and the first impeller 5 at this time carries out high speed rotation, moisture therein with
First impeller 5 rotates together, and under the influence of centrifugal force, moisture flies away from the first impeller 5 and projects outward, and the moisture of injection is being taken out
Speed is gradually slack-off in water cavity 3, and pressure gradually increases, and then flows out from outlet connection 21, at this point, at 5 center of the first impeller
Due to moisture be thrown toward around and formed both without the vacuum low-pressure area of the not no liquid of air, the liquid in waters is big in the water surface
Under the action of air pressure, water-inlet horn 2 enters the drawing water in chamber 3 of the inside of the pump housing 1, and moisture is exactly so continuously from waters
It is pumped up and is continuously flowed out from discharge pipe.
According to Fig. 1-5, and high-speed rotating first impeller 5 drive moisture project outward while, moisture along
3 inner wall of chamber that draws water of arc is flowed, thus water flow flow through draw water 3 inner wall bend of chamber when, due to the effect of centrifugal force, break
Cross current is formed in face, also referred to as secondary stream, cross current is superimposed with longitudinal mainstream movement, makes the 3 inner wall bend water of chamber that draws water
Stream helically flows motion state, and the silt in moisture is gathered in water flow spiral center under the drive of water flow screw at this time
Place, and outside moisture is then normally flowed out from outlet connection 21 normally through turbine 23 and filter 22, passes through 23 He of turbine in moisture
While filter 22, a small amount of silt is intercepted by filter 22 in moisture, and the water flow for passing through turbine 23 then drives turbine 23
It is rotated by connection ring 25 and mounting groove 26, while turbine 23 is rotated, turbine 23 drives bristle 24 to filter
22 carry out continue cleaning, avoid filter 22 from blocking, and in the 3 inner wall bend of chamber that draws water cross current movement moisture, then plus
Acute defeated shifting of the silt on cross section, so that being constantly washed at 3 inner wall depression of chamber that draws water, silt is then in 3 inner wall of chamber that draws water
High spot constantly deposits.
According to Fig. 1-5, while rotor 4 drives the first impeller 5 to be rotated, rotor 4 while band
Dynamic second impeller 10 carries out synchronous rotary by the ball 13 in link slot 12 on the pump housing 1, according to above-mentioned principle, the second impeller
10 extract outside moisture by inlet opening 20, and the moisture being extracted at this time is injected in containing cavities 6 by perfusing hole 9, from
And water flow drives the impact bead 7 in containing cavities 6 to carry out random motion, so that the inner wall of impact bead 7 and containing cavities 6 occurs frequently
It hits (similar to the principle of whistle), and containing cavities 6 are located at and draw water 3 inner wall raised position of chamber, at this time impact bead 7 and containing cavities 6
The shock vibration that occurs of inner wall adsorption of sediment can be prevented to be deposited in the 3 inner wall high spot of chamber that draws water, and be poured into containing cavities 6
Moisture by scour hole 8 ejection the 3 inner wall high spot of chamber that draws water is rinsed so that the silt for the 3 inner wall high spot of chamber that draws water by
The 3 inner wall corner spiral water flow of chamber that draws water is adsorbed, and when the water pump stops working, the silt of spiral water flow absorption then can be in weight
The chamber 3 that draws water is skidded off under the action of power, avoids blocking to inside the pump housing 1.
According to Fig. 1-5, and while rotor 4 drives the second impeller 10 to be rotated, the second impeller 10 is logical
Crossing tooth connection block 14 drives driving gear 15 to be rotated, and driving gear 15 at this time then drives angular wheel 16 to synchronize
Rotation, angular wheel 16 at this time drives mesh enclosure 17 to be rotated on the pump housing 1 by conical tooth block 19, so that moisture can lead to
The perforation 18 and inlet opening 20 crossed on mesh enclosure 17 are normally extracted, and mesh enclosure 17 that the sundries such as water plant can then be rotated carry out every
From, the case where avoiding the occurrence of blocking, such a water pump facilitate carry out using.
