Abstract

The utility model relates to a chopping dredge pump, comprising a pump body, a submersible motor, an impeller which is arranged at the motor shaft and a front pump cover. The head of the impeller is provided with at least two forward porrect movable blades, and the front pump cover is provided with at least two fixed blades which are uniformly distributed. The utility model has the following advantages: a cutting position is positioned at the inlet position of the impeller, so the quenched range of the impeller and the front pump cover is reduced, and therefore, the manufacturing cost is reduced; the adoption of a closed impeller improves the pump efficiency and reduces the energy loss; the cutting of the long fibers is exhaustive.

Description

Cut-up type blow-down pump
Technical field
The utility model relates to proof submersible sand discharging pump, particularly a kind of cut-up type blow-down pump.
Background technique
The chopper mill submersible pump of producing both at home and abroad mainly contains two kinds of forms at present:
1. impeller adopts semi-open type list or two blade impeller, cooperates the front pump cover end face of installing then to adopt a plurality of concentric V-arrangement grooves with blade, and long fibre is to cooperate with the V-arrangement groove by blade to grind, to realize grinding long fibre.
2. what impeller adopted is the semi-open type two blade impeller, cooperates the front pump cover of installing in import two blades to be set with blade, and long fibre is by semi-open type double-leaf and import two blades formation shearings to be set, to realize the chopping long fibre.
The shortcoming of the chopper mill submersible pump of above-mentioned two kinds of forms is: owing to adopt semi-open type list or double-leaf to cooperate chopping with pump cover, according to the water pump design theory, the hydraulic efficiency of half-opened impeller is generally than double shrouded wheel low 5%~10%, therefore its efficient is low, distribution power is big, waste energy, generally big one grade in practice than general expression impeller sewage pump match power, make manufacture cost increase.
Summary of the invention
Task of the present utility model provides a kind of improved cut-up type blow-down pump, and the hydraulic efficiency that it has solved existing half-opened impeller is low, and distribution power is big, wastes energy the problem that manufacture cost increases.
The technical solution of the utility model is as follows:
A kind of cut-up type blow-down pump, it comprises the pump housing, submersible motor, impeller of on motor shaft, settling and front pump cover, described impeller head is equipped with the movable blades that protracts more than two; Fixed blade uniform more than two is housed on the described front pump cover.
Advantage of the present utility model is as follows:
1. because cutting part is placed on the import position of impeller, therefore reduce the scope of the quenching of impeller and front pump cover, reduced manufacture cost.
2. the employing double shrouded wheel has improved pump efficiency, has reduced energy loss.
3. the cutting long fibre is comparatively thorough.
Description of drawings
Fig. 1 is the structural representation of a kind of cut-up type blow-down pump of the present utility model.
Fig. 2 is the impeller axial plane figure of Fig. 1 pump.
Fig. 3 is the paddle wheel plane figure of Fig. 1 pump.
Fig. 4 is the front pump cover axial plane figure of Fig. 1 pump.
Fig. 5 is the front pump cover planimetric map of Fig. 1 pump.
Embodiment
Referring to Fig. 1 to Fig. 5, a kind of cut-up type blow-down pump of the present utility model is mainly by the pump housing 1, submersible motor 2, and the impeller of on motor shaft, settling 3, front pump cover 4, movable blades 5 and fixed blade 6 are formed.
Movable blades 5 has two or three, is installed in impeller 3 heads with protracting.Fixed blade 6 also has two or three, evenly is installed on the front pump cover 4 with arranging.When manufacturing activities blade and fixed blade, should carry out Quenching Treatment, to improve blade hardness.
Gap between movable blades 5 and the fixed blade 6 is adjusted by the adjusting jackscrew 7 and the connecting bolt 8 that are placed on the pump.
During the utility model work, when long fibre enters pump inlet, under action of centrifugal force, divide laterally from central division and move, and enter between the movable blades and fixed blade of high speed rotating, thereby cut off long fibre, make it to become short fibre, enter again in the impeller, transfer out by pump chamber at last.

Claims (2)

1. cut-up type blow-down pump, it comprises the pump housing, submersible motor, impeller of settling on motor shaft and front pump cover is characterized in that, described impeller head is equipped with the movable blades that protracts more than two; Fixed blade uniform more than two is housed on the described front pump cover.
2. cut-up type blow-down pump according to claim 1 is characterized in that, the gap between described movable blades and the fixed blade is adjusted by the adjusting jackscrew and the connecting bolt that are placed on the pump.
