Abstract
The invention relates to a multilevel submersible sewage pump for large-scale mining. The multilevel submersible sewage pump for the large-scale mining comprises a motor, an impeller shaft, a pump body, an impeller chamber which is arranged in the pump body, a suction chamber and a delivery chamber, wherein the impeller chamber, the suction chamber and the delivery chamber are arranged in the pump body. The multilevel submersible sewage pump for the large-scale mining is characterized in that two ends of the impeller chamber are both communicated with the suction chamber, at least two groups of impellers are arranged in the impeller chamber, the forward and reverse of the impellers are symmetrically and evenly arranged on the impeller shaft, and the impeller chamber which is arranged between the forward and reverse impellers is communicated with the delivery chamber. The multilevel submersible sewage pump for the large-scale mining has the advantages that a sewage pump which can dive and has no blocked performance and the high lift of a common multilevel pump are provided. In addition, the reliability and the service life are far higher than the common multilevel pump.
Description
Technical field
The present invention relates to the fluid field, particularly the multistage proof submersible sand discharging pump of a kind of large-scale mine.
Background technique
Usually, proof submersible sand discharging pump is as Fig. 1, have the advantages that flow is large, lift is low, this is not content with the requirement of large coal mine with pump, at present, the multistage centrifugal pump of the non-diving use that the emergent pumping plant in general colliery is used is as Fig. 2, this pump service condition requires high, easily is out of order, and repair rate is high, and, when large water leak accident occurring, non-submersible motor can't work after by water logging.
Summary of the invention
The present invention seeks to overcome many deficiency factors of prior art, proposed the multistage proof submersible sand discharging pump of a kind of large-scale mine.
The present invention is achieved in that the multistage proof submersible sand discharging pump of a kind of large-scale mine, comprise: the blade wheel chamber of motor, impeller shaft, the pump housing, pump body, suction chamber and delivery chamber, it is characterized in that: the two ends of described blade wheel chamber all are communicated with described suction chamber, have two groups of impellers at least in blade wheel chamber, this impeller is forward and reverse to be arranged on impeller shaft symmetrically and evenly, and blade wheel chamber locates to be communicated with described delivery chamber between forward and reverse impeller.
Described impeller has 2 to 20.
Advantage of the present invention: have advantages of and the diving under water again without the property stopped up of pollution discharge pump there is again the high-lift of common multistage pump, and reliability and working life are far away higher than common multistage pump.
The accompanying drawing explanation
Structural representation Fig. 1 that Fig. 1 is prior art.
Structural representation Fig. 2 that Fig. 2 is prior art.
Fig. 3 is structural representation of the present invention.
Below in conjunction with drawings and Examples, the present invention is elaborated.
Embodiment
In figure, the multistage proof submersible sand discharging pump of a kind of large-scale mine, comprise: the blade wheel chamber of motor, impeller shaft, the pump housing, pump body, suction chamber and delivery chamber, it is characterized in that: the two ends of described blade wheel chamber all are communicated with described suction chamber, have two groups of impellers at least in blade wheel chamber, this impeller is forward and reverse to be arranged on impeller shaft symmetrically and evenly, and blade wheel chamber locates to be communicated with described delivery chamber between forward and reverse impeller.
The submersible motor that the motor of adapted is IP68, water pump can be designed to 2 to 10 grades (the present embodiment left and right respectively select 6 impellers), and flow is from 200 to 5000m
3/ h, lift is from 50m to 500m etc., and the highest 60m that can only reach of common pollution discharge pump lift, the present invention not only performance parameter far away higher than common pollution discharge pump, and good in common multistage centrifugal pump far away structure, structure of the present invention is that two ends suck, the middle discharge, the structure full symmetric is arranged, axial force is whole balances almost, greatly improved the working life of pump, because this pump is dived under water, so sealing is not required to (except motor), greatly reduced like this repair cycle of pump, the water conservancy of this pump is by designing without stopping up in addition, passing rate to impurity in medium is also strengthened greatly.
So this pump not only had advantages of diving under water of pollution discharge pump but also, without stopping up property, had advantages of again the high-lift of common multistage pump, and reliability and working life are far away higher than common multistage pump.
Below only expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Claims (2)
1. the multistage proof submersible sand discharging pump of large-scale mine, comprise: the blade wheel chamber of motor, impeller shaft, the pump housing, pump body, suction chamber and delivery chamber, it is characterized in that: the two ends of described blade wheel chamber all are communicated with described suction chamber, have two groups of impellers at least in blade wheel chamber, this impeller is forward and reverse to be arranged on impeller shaft symmetrically and evenly, and blade wheel chamber locates to be communicated with described delivery chamber between forward and reverse impeller.
2. the multistage proof submersible sand discharging pump of a kind of large-scale mine according to claim 1, it is characterized in that: described impeller has 2 to 20.
