Description
Technical field
The present invention relates to impeller, and in particular to the cloverleaf impeller for sewage pump.
Background technology
Dredge pump belongs to one kind of centrifugal impurities pump, has diversified forms：It is the most frequently used at present such as two kinds of submersible type and dry type
Submersible type be QW type proof submersible sand discharging pumps, most common dry type the dredge pump such as horizontal dredge pump of W types and WL types vertical sewage pump two
Kind.Mainly for delivery of municipal sewage, contain fiber in excrement or liquid.The medium of the solid particles such as paper scrap, is typically transported
The temperature of medium is not more than 80 DEG C.Due to containing the easily fibre object of winding or pack in the medium that is conveyed.Therefore this kind of pump runner
It is easy to block, pump can make pump cisco unity malfunction once being blocked, or even burn motor, so as to cause blowdown not smooth.To city
Life and environmental protection bring serious influence.Therefore, an important factor for anti-blocking and reliability are dredge pump qualities.
For the core of dredge pump in addition to motor, impeller is also important part, and the quality of impeller determines blowdown
The contaminant removal effectiveness of pump, the structure of impeller are roughly divided into：Open type and enclosed.
Its middle open type half-opened impeller is although easily manufactured, when being resulted in blockage in impeller, easily can clear up and tie up
Repair, but in longtime running, under the abrasion of particle the gap of blade and pumping chamber madial wall can increase, so that efficiency drops
It is low；The stifled property of the nothing of double shrouded wheel is poor, is easy to wind, and is unsuitable for pumping sewage Jie of the end containing bulky grain (long fibre) etc. through processing
Matter.
The content of the invention
The present invention to be solved impeller in the prior art blocking burn into efficiency it is low the problems such as, there is provided for sewage pump
Cloverleaf impeller, effectively solve block caused by efficiency it is low the problems such as.
The present invention is achieved through the following technical solutions：
For the cloverleaf impeller of sewage pump, including chassis, 3 pieces of blades, the chassis is shaped as disc, the bottom
The axle center of disk is provided with axis hole, and central siphon is also associated with the axis hole, and the diameter of the central siphon is identical with the diameter of the axis hole,
The central siphon is shaped as hollow cylinder, and 3 pieces of blades are uniformly arranged in the circumference of the central siphon, 3 pieces of blades
Size shape and weight all same, the shapes of 3 pieces of blades be it is streamlined, and blade all include blade tip, blade body,
Blade root, the blade root fastenings of the outer wall of the central siphon and the blade, the blade body of the blade are connected with chassis, the leaf
The blade tip of piece is arranged on the front end of blade body, and the blade root of the blade is arranged on the rear end of blade body, the blade root, blade
Body, the thickness of blade tip are sequentially reduced, and this design can increase stability；The design of 3 pieces of blades is compared with more than 3 pieces of impeller
Swirl space is increased, vortex can help to break up the impurity in sewage, such as shredded paper, hair etc., prevent the generation blocked；Stream
The blade of line style reduces the collision with impurity with common centrifugal blade contrast, substantially increases patency and non-destructive, institute
The combination connection of multiple impellers can be realized by stating central siphon, and multiple impellers can effectively improve the contaminant removal effectiveness of dredge pump, subtract significantly
The generation of small cavitation.
Further, the above-mentioned cloverleaf impeller for sewage pump, the lower surface setting on the chassis is fluted, described recessed
The shape of groove and the upper end shape of the blade match.Strengthen stability during multiple impeller combinations.
Further, the above-mentioned cloverleaf impeller for sewage pump, the quantity on the chassis be it is N number of, N be more than or equal to
1 natural number, when N is more than or equal to 2, multiple chassis are longitudinally superimposed, and axle center is located along the same line.
Further, the blade tip of the blade, the material of blade root are metal, and blade body material is synthetic rubber.Rubber has
There is the characteristics of wearability, anti-corrosion, long lifespan, also there is elasticity well, the main stress part as blade can absorb a lot
The energy brought is vibrated, improves the stability of impeller, and the convenient shaping of rubber.
Preferably, the radian of the blade is between 1.5rad to 2rad.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention not only solves the problem of common dredge pump easily blocks, and also improves contaminant removal effectiveness；
2nd, blade Shockproof abrasion resistant of the invention, long lifespan；
3rd, the present invention is applicable to a variety of different sewage types by changing impeller quantity.
