Background technique
At present, the big flow of domestic a lot of large-scale mine project demands, high-lift water pump, but be subjected to the restriction of landform or surrounding environment, the ground multistage centrifugal pump can't use and the Submerged Motor Pumps performance parameter does not reach usage requirement.For solving this difficult problem, strengthen project investment usually, with Submerged Motor Pumps and the supporting use of ground multistage centrifugal pump.And this supporting usage mode has not only increased project investment, has reduced system effectiveness, and has improved rate of breakdown greatly, has brought a series of problems such as energy-saving and environmental protection.
The model utility content
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of type spectrum scope to cover the mining draining pump of large-scale submerged type of the existing mining multistage draining pump and the work of can diving beneath the water.Its technological scheme is:
Comprise and be installed in the large-scale Water-filled Type Submersible Motors of inhaling in the cover, multistage centrifugal pump, cable and the connected body that is connected submersible motor and multistage centrifugal pump, it is characterized in that: multistage centrifugal pump comprises the main shaft of fixedlying connected with the submersible motor output shaft, suck the Spit Section, last suction casing, impeller, the stage casing, stator, the section of catchmenting, turnbuckle, the anti-ballistic wing and following suction casing, wherein impeller divides two groups up and down, two groups of impellers are symmetric arrangement in opposite directions, impeller in every group and corresponding stator thereof are sleeved on the main shaft and correspondence is pressed in the stage casing, and stator is between impeller and stage casing, stator and stage casing are fixedly connected, impeller is connected with main shaft key, the a plurality of stage casings and the Duan Jun that catchments are sleeved on the main shaft, be pressed with the stage casing of group impeller, the section of catchmenting and be pressed with down the group impeller the stage casing be connected as a single entity through turnbuckle, the section of catchmenting is positioned at the exit position of group impeller, and the anti-ballistic wing is contained on the main shaft and is positioned at the exit position of group impeller down.
The mining draining pump of described large-scale submerged type, main shaft is divided into upper and lower two-part, and is fixedly connected through box coupling.
The mining draining pump of described large-scale submerged type, connected body in the middle of being provided with between the stage casing of group impeller below the section of catchmenting and under being pressed with, the stage casing and the section of catchmenting that are pressed with the group impeller are connected as a single entity through the upper end of turnbuckle and middle connected body, the connected body of connection submersible motor, are pressed with down the stage casing of organizing impeller and are connected as a single entity through the lower end of another turnbuckle and middle connected body.
Its working principle is: sewage enters impeller by sucking Spit Section and upper and lower suction casing during the multistage centrifugal pump operation, flows into the next stage impeller by stator after the impeller acting throws away.Effluent stream is after the section of catchmenting in higher level's centrifugal pump, flows out from sucking the Spit Section by runner, and connected body in the middle of subordinate's centrifugal pump is flowed through and flowed through behind the anti-ballistic wing flows out from sucking the Spit Section by runner again.
The utility model compared with prior art has following advantage:
1, because the axial hydraulic thrust equal and opposite in direction that two groups of impellers of multistage centrifugal pump produce when adopting symmetric arrangement unit operation in opposite directions, direction is opposite, and total axial force is zero, has prolonged unit working life, and is safe and reliable to operation.
2, multistage centrifugal pump with can dive into underwater operation after the large diving motor connects, can reach the high-lift performance parameter of ground multistage centrifugal pump high volume and have submersible pump does not simultaneously have the suction journey, noise free, the efficient height, floor space is little, the advantage of energy-conserving and environment-protective.
3, the type spectrum scope covers existing mining multistage draining pump, and is not inhaled degree system, applied range.
