Abstract
The utility model provides a high-flow how-head submersible motor pump for mines. The high-flow low-head submersible motor pump for the mines is structurally composed of an upper pump cover, an upper end cover, a motor casing, a motor, a bearing, a lower end cover, a mechanical seal, a guide vane, an impeller and a base. The motor is mounted in the motor casing, the upper end cover and the lower end cover are respectively arranged on the top of the motor casing and the bottom of the motor casing, the upper pump cover is arranged above the upper end cover, the bearing is arranged between a motor shaft of the motor and the lower end cover, the mechanical seal is arranged between the motor shaft and the lower end cover, wherein the motor shaft is located below the bearing, the guide vane is arranged on the base, the impeller is arranged on a water inlet of the guide vane, the water inlet of the guide vane is connected with the lower end portion of the motor shaft of the motor, the motor casing is arranged above the guide vane and in an interlayer structure, and a water outlet of the guide vane is communicated with the interlayer of the motor casing. A built-in type structure is adopted by the motor of the motor pump, namely disposed sewerage flows out from the interlayer of the motor, and thus traditional ways that sewerage is discharged from a water outlet pipe directly by the impeller and a volute are broken. Therefore, the high-flow how-head submersible motor pump for the mines has the advantages of high efficiency, long service life and compact structure. The power of the matched motor is 400-600kw.
Description
Technical field
The utility model relates to a kind of mining submersible dirty water electric pump, specifically a kind of large flow low-lift mining submersible dirty water electric pump.
Background technique
General mining submersible dirty water electric pump adopts traditional impeller and the form of spiral case that fed sheet of a media is discharged from the outlet pipe of pump lower end.When draining, the volume concentration of solid particle generally is no more than 4% in the fed sheet of a media; General 10～the 15mm of the maximum particle diameter of solid particle in the fed sheet of a media.General mining submersible dirty water electric pump in actual use, the solid particle in the fed sheet of a media, high viscosity sludge and the easy clogging impeller of long fibre be so that pump can't draining, even damage electric pump.So greatly affected the using scope of general mining submersible dirty water electric pump.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides that a kind of efficient is high, the life-span is long, the large flow low-lift mining submersible dirty water electric pump of compact structure.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of large flow low-lift mining submersible dirty water electric pump, comprise pump cover, upper end cap, motor casing, motor, bearing, lower end cap, mechanical seal, stator, impeller and base, described motor is arranged in the motor casing, the top of motor casing and bottom are respectively arranged with upper end cap and lower end cap, the top of upper end cap is provided with pump cover, be provided with bearing between the motor shaft of motor and the lower end cap, between the motor shaft below the bearing and lower end cap, also be provided with mechanical seal, be provided with stator on the described base, the water inlet of stator is provided with impeller and is connected with the underpart of the motor shaft of motor, motor casing is arranged on the top of stator and is sandwich structure, and the water outlet of stator is connected with the interlayer of motor casing.
The flow-passing surface of the shaft section of described stator takes the shape of the letter U or near the U-shaped structure, its bottom is water intake, and top is annular water outlet, the middle cavity that holds mechanical seal that forms.
The flow-passing surface of the shaft section of described impeller is V-shaped or near v-shaped structure, its bottom is water intake, the annular water outlet of top for being connected with stator, the middle cavity that holds motor shaft that forms.
A kind of large flow low-lift mining submersible dirty water electric pump of the present utility model compared with prior art, the beneficial effect that produces is:
1) this electric pump motor adopts the built-in type structure, and namely institute's sewer flows out from the motor interlayer, the impeller that breaks traditions, spiral case are directly discharged sewage from outlet pipe mode.
