In order to further increase self priming pump operating efficiency, the utility model proposes a kind of new efficient check self-priming volutes Pump, structure includes power source, volute, impeller and non-return valve；Impeller is in volute；The water inlet connection non-return valve of volute Water outlet；Power source connects driving impeller by transmission mechanism；The impeller includes wheel disc and multiple blades；The bottom of each blade Face is connected to wheel disc front, and in a center of symmetry around the axle center of wheel disc.Each blade is connected to wheel disc front vertically；
The top surface of each blade is in same plane；It is detachably connected with partition board on the inner wall of the water inlet side of volute； The inner wall of the first face of partition board and the water inlet side of volute is closely connected；The second face of partition board is smooth, the top surface of each blade and partition board Second face is closely connected；
The first side and second side of each blade are all arcs, and the thickness of blade outer rim is more than the thickness of vane inside edge Degree；The outer rim of blade and the outer rim of wheel disc in same cambered surface, the inner edge of each blade on the outer wall of same round platform, round platform It is axial identical as the shaft of impeller, the water inlet of the larger bottom of round platform towards volute；
The front of wheel disc surrounds truncated conical shape, the water inlet of the smaller big bottom of truncated conical shape towards volute.
The principle of this self-priming volute pump is that casting and requirement on machining accuracy of the volute with blade mating surface can slightly be dropped Low, using dismountable partition board lining between volute inner wall moon blade top surface, partition board coordinates with blade.In terms of processing, The difficulty of processing of partition board is relatively low, and is conveniently adjusted and replaces.The specific structure of impeller is processed convenient for casting, even if the arc of blade It is special that degree requires, and can also be realized by sand mo(u)ld.
In the prior art, in order to ensure the suitable position that flap can reach valve seat every time, flap design has Link chain device Structure has rotation to open space, and flap is made really, comprehensively with valve seat to contact enough so that flap has.Linkage needs The mechanisms such as shaft and corresponding bearing are set on valve body, and after prolonged use, these are potential leak points.Meanwhile this The precision of a little mechanisms is higher, and difficulty is brought to the maintenance in use.
For this purpose, further, the non-return valve includes valve seat and clack valve, and clack valve is connect with valve seat；The valve seat is cylinder Type；Plane where the end face of the water inlet of valve seat is face a, and plane where the end face of the water outlet of valve seat is face b；Drum type valve seat The angle of axis l and face a institutes angulation be 90 degree, axis l is acute angle with face b institutes angulation；

The clack valve includes fixed part and movable part；Clack valve fixed part is annulus shape, and multiple through-holes are provided on annulus, The position of these through-holes is corresponding with the position of the pilot hole in second flange；Clack valve fixed part is detachably connected to second flange On；
Clack valve movable part includes cake type main body；Cake type main body includes the metal core of rubber outer protection set and cake type, rubber Airtight cavity is set in glue oversheath, metal core covers tight in airtight cavity, and by rubber outer protection；The clack valve fixed part It is rubber material, is connected by rubber connection strap between rubber outer protection set and clack valve fixed part；
State of the clack valve movable part on the b of face, metal core are completely covered on the b of face.
The principle and application method of this non-return valve be：
The water outlet of non-return valve is sleeved on clack valve fixed part outside the water outlet of non-return valve towards the water inlet of self priming pump, and It is bonded with second flange.Clack valve movable part is covered by gravity on the b of face.
Then the water outlet of non-return valve is stretched into the water inlet of self priming pump, and the method for second flange and self priming pump water inlet Orchid connection.At this point, clack valve fixed part is sandwiched between two flanges.Here, clack valve fixed part can also play the role of sealing ring.
When self priming pump operation, the pump housing generates negative pressure to clack valve position, and water washes clack valve movable part open and enters the pump housing. When the negative pressure deficiency that self priming pump generates (positive pressure when) under even certain operating modes, heavier metal core drives clack valve to live Dynamic portion is covered on the b of face, so that clack valve is had preferable sealing effect in conjunction with face b and axis l institutes are at an acute angle, is played the role of non-return.
By the specific structure of this non-return valve so that vulnerable part clack valve can be convenient for changing.
Further, clack valve fixed part is not attached in the state of second flange：
The thickness of clack valve fixed part is d1, is by the thickness of rubber connection strap between rubber outer protection set and clack valve fixed part d2；
Airtight cavity is connected to round rubber on piece by drum type rubber cover and constitutes, and the thickness of round rubber piece is d3, d1 =d2=d3；
And the bottom surface of the bottom surface of clack valve fixed part, the bottom surface of rubber connection strap and round rubber piece is coplanar.
Under the structure, clack valve integrally has preferable machinability, and the disposable injecting glue of mold both may be used and constituted, also may be used To be first to press sheet rubber, then injecting glue forms drum type rubber cover, finally plays the effect of sealing metal core.
Further, the structure of the clack valve fixed part, rubber connection strap and rubber outer protection set is all braiding layer outer wrapping rubber Glue material.
Since the motion frequency between the movable part and fixed part of clack valve is higher, and rubber is avoided to be influenced by temperature etc. Extension/contraction, so setting braiding layer in rubber plays booster action.
To sum up, the non-return valve is reasonable for structure, opens that consumption energy is smaller, and sealing effect when closing is preferable, uses Maintenance facility in the process, product better working stability.
Further, the power source is motor；Motor is connected on volute outer wall, and the output shaft of motor is logical It crosses the axis hole issued on volute and stretches into volute, and pass through key connection with impeller；It is connected between axis hole and the output shaft of motor Axle envelope.
The utility model may insure the machinability of Functional Design, and ensure self priming pump by multiple detailed designs Efficient operation.
