Abstract

The utility model relates to a mining immersion pump mainly comprising an assembling unit comprising a motor and a pump body, and a sealed outer cover. The assembling unit is fixed in the sealed outer cover, and the two ends of the sealed outer cover are respectively equipped with a water intake and a water outlet. A flowing water interlayer is provided between the assembling unit and the sealed outer cover. The motor adopts the ground motor of Y series, and a sealing device is arranged on the part of the motor shaft extending onto the front end cap of the motor. The pump body adopts the IS single-stage centrifugal pump or D, DG type multiple-stage centrifugal pump. The utility model has the advantages of safety, high efficiency, simple structure, light weight, and small volume. The axial vertical height is only 1/3 to 1/5 of the axial vertical height of a common submersible pump, and the height is 1/2 to 1/3 of the height of a common submersible pump. When the water passes through the flowing water interlayer, the water produces cooling effect to the assembling unit simultaneously. The assembling unit of the utility model can adopts a horizontal type or a vertical type. The utility model is in particular suitable for pumping and draining clear water in a small space and a bad environment such as underground mining or various sewage including solid particles.

Description

The new type mining submersible pump

Technical field the utility model relates to the water pump that a kind of draining is used, and is submersible pump specifically.

The background technique water pump is the common equipment that draining is used.Water pump mainly contains motor and two parts of the pump housing, and the pump housing is made up of the pump shaft in pump case, the pump case, the impeller that is fixed on the pump shaft, and motor shaft and pump shaft are connected together.During work, motor shaft drives pump shaft, wheel rotation, discharges it again in just that pump is the outer water suction pump and locates.Difference according to Environmental Conditions, water pump has two kinds of submersible pump and centrifugal pumps: be vertical connection between the motor of submersible pump, the pump housing, this pump has the advantage of protection against the tide, waterproof, but because unit is higher, so this pump be not suitable for the space narrow and small mine in use, and it is convenient inadequately to install, use, and damages easily in the transportation; So far the drainage equipment that uses in the mine adopts centrifugal pump more, its motor and the pump housing horizontally connect, flat crouch and fix on the ground, its advantage is to need not high space, but equipment very easily makes moist, cause the insulation of motor to descend, bring hidden danger to safety, especially, in case it is permeable mine to occur, water is easy to enter motor, easily causes the accident of burn-down of electric motor.

Model utility content the purpose of this utility model is, provide a kind of simply, safely, take up space little, the submersible pump that can in mine, use.

The utility model is achieved in that the utility model mainly is made up of unit and sealing cover.Unit is fixed in the sealing cover, is to be formed by connecting by the axle of the two by motor, the pump housing; The flowing water interlayer is arranged between unit and the sealing cover, and the two ends of sealing cover have water intake and water outlet respectively.Motor adopts the Y series ground surface motor that iron core is short, diameter is bigger, and there is seal arrangement at the motor front cover position of motor shaft, to prevent the motor water inlet; Pump housing employing IS single stage centrifugal pump or D, DG type multistage centrifugal pump, the characteristics that utilized the axial dimension of this centrifugal pump short, lift are high.

During work, starting electrical machinery, motor shaft drive pump shaft, impeller rotates together, and along in the water intake suction pump, by the impeller pressurization, water longshore current water interlayer flows, and is discharged by water outlet at last then with the water of outside.

The utility model is simple in structure, volume is short and small, and its axial vertical height only is 1/3～1/5 of a submersible pump commonly used, and weight is 1/2～1/3 of submersible pump commonly used; By the unit that motor, the pump housing are formed by connecting, both can be level and install, also can be vertical installation.The utility model is safe and reliable, is particularly useful for pump drainage such as water that air-conditioning is little, environment is abominable such as down-hole mining, and this water can be clear water, also can be the sewage that contains solid particle (such as coal slime, slag, cinder, sand etc.).When water passes through, simultaneously unit has been produced good cooling action in the flowing water interlayer.
