The well submersible pump is multistage pump, is made up of motor, the pump housing.The pump housing is made up of pump shaft, several modular pumps, pump head, superimposed fixing device.Modular pump is made up of a spiral case, an impeller, water conservancy diversion leaf, the pump shaft section of walking.Spiral case is the taper cylinder that Open Side Down, tubular body of disjunctor extension on the cover mediad on it, and cylinder outer wall upper end portion is provided with circular groove, is sheathed with rubber seal in the circular groove.Impeller shape is uniform several arc plate blades of disjunctor between the circle ring disk up and down, last circle ring disk central hole upwards reaches sleeve body of downward disjunctor, the sleeve body inwall is provided with keyway, tubular body of the downward disjunctor extension of following circle ring disk central hole, circular diameter is greater than circular diameter in the last circle ring disk sleeve body in the following circle ring disk tubular body.The water conservancy diversion leaf is shaped as uniform several the vertical upright arc plates of circle ring disk upper surface disjunctor, water conservancy diversion leaf cylindrical is tightly fixed on the spiral case inwall, a pump shaft that is connected with motor output shaft passes several modular pumps, the circle ring disk sleeve body is the key coupled condition on pump shaft and each the modular pump impeller, also make simultaneously impeller be positioned the water conservancy diversion leaf with high positions such as layers, circle is state movingly in impeller cylindrical and the water conservancy diversion leaf.Each modular pump spiral case cylinder upper end portion rubber seal is implemented to seal with a last modular pump spiral case inwall underpart and is docked, the top modular pump spiral case is implemented to dock with the pump head spiral case, superimposed fixing device is implemented superimposed fixing with several modular pumps and pump head, and enforcement simultaneously is connected and fixed with motor.Driven by motor pump shaft rotation during operation, the paragraph key of walking that pump shaft passes modular pumps at different levels connects drive impellers rotations at different levels, during the impeller rotation fore pump entry is applied centrifugal force by impeller blade and squeeze into peripheral water conservancy diversion leaf, the water conservancy diversion leaf is because bottom circle ring disk capping, water can only be by vertical upright arc plate drainage, upwards clamp-on the space between the cover inwall on impeller upper surface and the spiral case, flow into the next stage modular pump by the space between cover tubular body on the spiral case cylinder and the impeller Upper shaft sleeve body again, be that water is pressurizeed by the multi-stage impeller successive, form high head and got by pipeline by pump head.
The applicant has improved the modular pump structure in addition, becomes upper and lower layers stacked with impeller and the water conservancy diversion of same level are leaf, has enlarged impeller outer diameter, to improve lift.But impeller and the pump shaft section of walking Connecting format are constant.Structure is: comprise spiral case, rubber seal, impeller, water conservancy diversion leaf, the pump shaft section of walking, it is characterized in that: the water conservancy diversion leaf that fixed cover is combined on the spiral case is the circle ring disk of uniform several breach, the water conservancy diversion leaf circle ring disk central hole sleeve body of disjunctor that makes progress, circle is enclosed within outside the external circle of impeller Upper shaft sleeve in the water conservancy diversion rachis body, and water conservancy diversion rachis cover body diameter is less than cover tubular body internal diameter on the spiral case; Form the breach that one section flat-cut line and curved line make up on the water conservancy diversion leaf circle ring disk between uniform several vertical upright arc plates between water conservancy diversion leaf cylindrical and the sleeve body cylindrical, the vertical upright arc plate outer of adjacent each and adjacent vertical upright arc plate middle part; Circle ring disk upper surface and water conservancy diversion leaf lower surface maintain the gap on the impeller, and the circle ring disk external diameter is less than circle ring disk external diameter under the impeller on the impeller, and the circle ring disk external diameter is than the little 1-2mm of inwall internal diameter in the corresponding orientation of spiral case under the impeller.
The impeller circle ring disk enlarges the back to be dwindled with spiral case inwall spacing and could improve lift, because described spacing dwindles, so the circle ring disk external diameter must be littler than following annulus external diameter on the impeller, be beneficial to water and make progress to push and enter the water conservancy diversion leaf.It is for water upwards enters the water conservancy diversion leaf from breach that the water conservancy diversion leaf arranges breach, through vertical upright arc plate water conservancy diversion, enters spiral case upper tubular body again, flows into the next stage modular pump.
There is same defective in said structure: impeller with water upwards the row of squeezing bear downforce, this downforce passes to pump shaft by impeller with fixedlying connected of pump shaft, pump shaft forms axial downforce and passes to motor output shaft, and the multistage pump downforce is added up by modular pump downforce at different levels.The motor output shaft pressure-bearing is excessive, make the wearing and tearing of motor bearings ball not only big but also fast, ball wearing and tearing back produces the vicious circle wearing and tearing of the irregular operation of complete all balls, bearing not only produces axial clearance, also follow radial clearance to produce, the output shaft precision reduces the normal operation of influence, and otherwise periodic replacement bearing.Changing bearing not only influences work efficiency, has also improved operating cost.We it is contemplated that, set up a thrust-bearing in mechanism, but excessive downforce concentrates on the thrust-bearing, and the same quick abrasion influence of thrust-bearing operation must regularly be carried out thrust-bearing and change operation, influences work efficiency and cost.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and the modular pump structure of a kind of well with submersible pump loop type impeller is provided.
Scheme of the present utility model is: comprise spiral case, rubber seal, impeller, water conservancy diversion leaf, the pump shaft section of walking, it is characterized in that: circle ring disk sleeve body inner hole section is square shape chamber or regular hexagon shape chamber on the impeller, the pump shaft section of walking cross section is corresponding square or regular hexagon, and the pump shaft section of walking is linked in the shape chamber of circle ring disk sleeve body correspondence on the impeller movingly.
Advantage of the present utility model is: the impeller kink is in pump shaft, and pump shaft does not bear down pressure, and motor is operated steadily.
