Abstract

The utility model discloses a suction-in type submerged electric pump, wherein, a water pump is arranged on a base disk; an electric motor is suspended on the base disk; the base disk is arranged on the upper mouth of a water chamber; the electric motor is arranged in the water chamber; the interior of the water chamber is provided with a suction pipe barrel; the upper mouth is hermetically connected with the suction mouth of the water pump; the electric motor is positioned in the suction pipe barrel; the water chamber is provided with a water inlet; a sealed negative-pressure chamber arranged at the position which is higher than the suction chamber of the water pump is respectively communicated with the suction chamber of the water pump and the water chamber to ensure the submergence of the submerged bearing of the electric pump, etc. The utility model used for the drainage of a mine has the advantages of small ground occupation, convenient installation, easy wearing part replacement, convenient monitoring operation and no special requirements to water quality.

Description

Suction in type submerged electric pump

The utility model relates to a kind of improved mining Submerged Motor Pumps, specifically is exactly a kind of inhalation type Submerged Motor Pumps.

The existing electric pump that is used for mine drainage is a kind of to be common pump for sleeping in, it is more extensive that this pump uses, but its major defect is can not be submerged in the water to work, in case water bursting in mine, the pump house water inlet, it will lose drainage capacity, and mine just has covered danger, so people propose and will replace common pump for sleeping in Submerged Motor Pumps gradually; Existing Submerged Motor Pumps is not afraid of water logging, has very strong anti-disaster ability, but if it is used as the main pumping equipment of mine, have very big shortcoming: (1), existing Submerged Motor Pumps are more suitable in the boring sewer drainage, for dwindling bore diameter to reduce construction investment, the electric pump body is elongated, and radial dimension is restricted, make its structural design and parameter select to be affected, thereby hindered selecting for use rational structure and best parameter; (2) existing Submerged Motor Pumps is used for mine drainage and mostly is the pump sump hanging and installs, but this pump requires certain depth of immersion again, pump house is higher, pump sump is darker, engineering work load is big, and it is very difficult to construct, and (3) dive that pump assembly installation and removal are taken a lot of work, effort, easily damaged parts are changed very inconvenient, (4) too high to water quality requirement, be not easy to the monitoring operation.Find out that from above above-mentioned electric pump is used for not really ideal of coal mine main pumping equipment.

The purpose of this utility model is to provide one respectively to be convenient to installing/dismounting, easily damaged parts and to overhaul replacing easily, be convenient to the inhalation type Submerged Motor Pumps of guarding operation and water quality not being required basically.

The purpose of this utility model is to realize like this.Motor is lifted on the attic base, water pump is installed on the attic base by bearing, and motor placed in the hydroecium, link up with the axle of coupling water pump and motor, the lower end of hydroecium is provided with water intake, have a suction socket at attic base, its suitable for reading and water pump suction port is connected, and motor is positioned at this suction socket.

The utility model is compared with conventional art has following advantage: it is simple in structure, and volume is little, and required pump house height is low, easy installation and removal, and easily damaged parts is changed easily, and is not high to water quality requirement, is convenient to the monitoring operation.

Accompanying drawing 1 has provided an embodiment's of the present utility model structural representation.

Below in conjunction with accompanying drawing the utility model is described further.

With reference to Fig. 1, water pump 2 usefulness bearings 1 are installed on the attic base 4, motor 9 is lifted on the attic base 4 by flap seat 5, link up with the axle of coupling 6 water pump 2 and motor 9, attic base 4 is installed in the suitable for reading of hydroecium 8, and motor 9 places in the hydroecium 8, below attic base 4, be provided with a suction socket 10, the suction port of the suitable for reading and water pump 2 of suction socket 10 is tightly connected, and lower ending opening, motor 9 are positioned at this suction socket 10, be provided with water intake 7 in the lower end of hydroecium 8,10 fens two-part of suction socket, top and water pump (2) are designed to one, and the bottom independently is provided with, be connected to integral body by bolt during installation, make also more conveniently, in a side of water pump 2, the position that is higher than water pump 2 suction chambers also is provided with an airtight negative pressure chamber 3, communicate with the suction chamber and the hydroecium 8 of water pump respectively, can soak in water at any time with the submerged bearing that guarantees water pump 2 etc.

Also water pump 2 can be adopted and horizontally install at an angle of 90 with motor, coupling is by bearing and gear wheel reversing; Also water pump 2 and motor 9 all can be adopted horizontal connection in addition, but suction sleeve 10 should extend and bending is installed at an angle of 90, above mounting type all is applicable to mine very much, applies easily.

Claims

1, a kind of Submerged Motor Pumps that has bearing 1 and flap seat 5, it is characterized in that water pump 2 utilizes bearing 1 to be installed on the attic base 4, motor 9 is lifted on the attic base 4 by flap seat 5, and places in the hydroecium 8, links up with the axle of coupling 6 with water pump 2 and motor 9, attic base 4 is installed in the suitable for reading of hydroecium 8, and with hydroecium 8 sealings suitable for reading, the lower end of hydroecium 8 is provided with water intake 7, has a suction socket 10 at attic base 4, its suitable for reading and water pump suction port is connected, and motor 9 is positioned at this suction socket 10.

2, by the described Submerged Motor Pumps of claim 1, it is characterized in that being provided with a negative pressure chamber 4 being not less than water pump 2 suction chamber height, it communicates with suction chamber, the hydroecium 8 of water pump 2 respectively.
