Description
(1) technical field
The utility model relates to a kind of water pump, relates to a kind of mixed flow booster pump that docks operation with the large diving pump that is specially adapted to all kinds of mine emergency drainages specifically.
(2) background technique
In mining,, the down-hole gushing water happened occasionally by the accident of flooding because of causing mine.And one of effective measures that this class burst accident is rescued are exactly that the large diving pump is once drained ponding to the shaft bottom down.But because large diving pump profile is big, tonnage is heavy, and its water intake is arranged on the upper end or the middle part of the pump housing more, therefore when no lum or the water nest degree of depth are not enough, must connect the relay water pump in the lower end of large diving pump, carry out emergency drainage to the method that main pump supplies water by the relay water pump.
Traditional relay water pump mostly is axial-flow pump, and its structure as shown in Figure 1.Be equipped with during as can be seen from Figure 1 it comprises in its cavity stator 7 ' and rotor 6 ', the bottom be provided with suction guard 12 ', top be provided with the flange 1 that pumps up water ' electric machine casing 8 ' (also as the pump housing), described rotor 6 ' be a hollow cylinder structure, combine with pto in vertically being installed on its hollow cavity by the link that is provided with at interval in its hollow, be used to aspirate the water wheels 9 of fed sheet of a media ' be installed in the pto that is positioned at the rotor hollow cavity by conjunction, the formula of getting lines crossed staor winding 5 ' by terminal box 2 ' with power line 3 ' be connected.Its working principle is as follows: when the relay pump operation, water wheels suck water in the rotor hollow cavity by the suction guard under the drive of pto, flow through and pump up water flange to the large diving water supplying pump, the mine water level can be drained into suction guard bottom, the height of suction guard is generally 300-400mm.
The existing deficiency of above-mentioned traditional relay water pump is as follows:
A, because due to the structure characteristic of the booster pump of prior art, make the complete machine running gear be immersed in the water all the time, and with water as lubricant medium, and its staor winding very easily is subjected to the impact of current and impurity, in real work,, generally generally can only use as disposable products because its rate of fault is higher;
B, because its staor winding heart yearn is linked up by cable and atmosphere, cause the inner pressure reduction increase with extraneous hydraulic pressure of winding, cause the immersed depth of the booster pump of this prior art can not surpass 70 meters limits;
(3) summary of the invention
The purpose of this utility model is exactly to provide in order to overcome existing deficiency in the above-mentioned prior art that a kind of structure is more reasonable, rate of fault is low, long service life, the unrestricted mixed flow booster pump of immersed depth.
The purpose of this utility model can realize by following measure:
Mixed flow booster pump of the present utility model comprises that its underpart is provided with the pump housing of suction guard, vertically be installed in motor in the pump housing by link, and the water wheels that are installed in motor shaft end, wherein said motor is for being filled with the full closed structure of lubricant medium in its inner chamber, this motor by be disposed between its frame and pump housing inwall be connected stiffening rib and the pump housing combines; The toroidal cavity that is arranged between motor and the pump housing inwall is the medium output channel; The water wheels that are positioned at pump housing lower chamber are installed on the motor power output shaft by link.
The wiring terminal that is used to connect power supply in the utility model is installed on the motor upper end cap by the mounting type of insulating material and high pressure sealing, the wiring terminal lower end that is positioned at the airtight cavity of motor is connected with staor winding, and the upper end of wiring terminal is arranged in the airtight terminal box.
Working principle of the present utility model is as follows:
During the work of mixed flow booster pump, water wheels suck current by the suction guard under the drive of motor power output shaft, and current are admitted to main pump via the annular medium output channel between motor and the pump housing inwall by the flange that pumps up water on the pump housing.And the flow process that current are discharged via the annular medium output channel between motor and the pump housing inwall, the lucky effect that has also played cooling motor.
Because the motor inner chamber in the utility model mixed flow booster pump is a full-closed structure, at work, not only can effectively avoid the impact of current to stator in the motor and rotor, prolong the working life of motor greatly, and can make each moving element avoid the infringement of impurity in the water, remain good lubricating status, and then is greatly improved the working life of complete machine.In addition, because the change of the power line mode of connection in the utility model, efficiently solve in the prior art and link up the problem that the inside and outside pressure reduction of the motor that is caused increases by cable and atmosphere because of the staor winding heart yearn, prolonged the working life of motor, main is that the immersed depth of booster pump is greatly improved, and can accomplish not to be subjected to the restriction of immersed depth.
