Abstract
The utility model discloses a drainage electric pump for amphibious mines, wherein, an electric motor adopting a closed type water-cooled machine is connected with a water pump through a shaft coupler and a water-proof lubricating bearing device with a completely sealed structure; a bearing bracket is arranged separately from a main body; the electric motor is connected with a circulating water pump chamber via the bearing device; the recirculating cooling water of the electric motor is drained through a pipe, and after pumped into a cooling device by the water pump and cooled by the cooling device, the water is delivered back to the circulating water pump chamber and the electric motor. The utility model which is capable of running in the open air and running in water has the advantages of simple structure, convenient installation, no special requirements to the pump room and the water quality, high anti-disaster ability, etc.
Description
The utility model relates to a kind of improved mine drainage electric pump, is exactly a kind of amphibious mine drainage electric pump specifically, is comparatively ideal coal mine main pumping equipment.
In the prior art, the electric pump that is used for mine drainage has two types, a kind of is common pump for sleeping in, use the most extensively at present, its topmost defective is that anti-disaster ability is poor, and it can not be submerged in the water and work, in case water bursting in mine, the pump house water inlet, it will lose drainage capacity, and whole mine just has the danger of being flooded, and after mine floods, can't utilize existing equipment to combat a natural disaster draining, during secondly this pump operation, often make that temperature is too high in the pump house, noise is excessive, and up to the present, large-scale anti-explosion motor and decompression starting equipment all also do not solve; Another kind is a Submerged Motor Pumps, because there is the following shortcoming in it, uses also seldom at present.The first, this pump is more suitable in the boring sewer drainage because its pump housing is elongated, if be used for mine drainage, its structure is also unreasonable; The second, existing submersible pump is used for mine drainage and mostly is the installation of pump sump hanging, and the pump body of diving is longer, and this pump requires that certain depth of immersion is arranged, and pump sump is darker, and pump house is higher, and it is very inconvenient to construct; The 3rd, this pump assembly installation and removal effort of taking a lot of work, overhaul very inconvenient, the 4th, it is too high to water quality requirement, requires to dive beneath the water certain depth again, be not easy to guard and move.Therefore above-mentioned two kinds of electric pumps are very undesirable as coal mine main pumping equipment.
The purpose of this utility model provides and a kind ofly can resemble the common pump for sleeping in air operation and can resemble again to be submerged in the water the Submerged Motor Pumps and move, and is easy to maintenance is installed, and is convenient to guard the discharge electric of operation.
The utility model is to realize like this, bearing bracket stand of the present utility model and main body set up separately, bearing adopts water-fast lubricant oil and all-sealed structure, motor adopts the sealed type water-cooling pattern, recirculated cooling water water pipe in the motor body is derived, send back in the motor body after a cooling unit is with its cooling again, motor connects with a circulating water pump chamber, make cooling liquid form circulation, recirculated cooling water cools off with the water inlet of pump sump.
The utility model compared with prior art has simple in structurely, easy for installation, and characteristics such as applicability is strong are convenient to the monitoring operation, and pump house and water quality are not had the characteristic requirement, and anti-disaster ability is big.
Accompanying drawing 1 provides the utility model one embodiment's structural representation.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, motor 3 is through bearing means 2,4,6,9 and coupling 5 connect with circulating water pump chamber 1 and water pump 7, in the circulating water pump chamber 1 is single-impeller pump, it is coaxial with motor 3, its pure neutral water that temperature is lower is sent into the cooling chamber of sealed mode water-cooled machine 3 through circulating pipe 12, bearing means 2,4,6,9 adopt water-fast lubricant oil and all-sealed structure, basic identical, can guarantee to flood in water, anti-sealing enters in the bearing chamber, even flood when moving in water when the pump group, just in case the sealing of bearing chamber is destroyed, water-fast lubricant oil still can guarantee the normal operation of bearing.The cooling unit 8 that links to each other with water pump 7 is tubulose, and two ends have connecting head, and the circulating water of drawing from the motor cooling chamber passes through cooling unit 8 through going out pipe 10, adopt multitube to pass through side by side, come water cooling with pump sump, the two-way flow reversal does not mix mutually, good cooling results, lead back circulating water pump chamber 1 through cooled circulating water with circulating water inlet pipe 11, send motor 3 back to by circulating water pump chamber 1 again, realize the circulation of cooling water, the mine water inlet sucks water pump 7 through the A mouth, discharges through the B mouth.
In addition, bearing means 2,4,6,9 also can adopt submerged bearing, the water lubrication and the cooling that utilize circulating water pump chamber 1 to extrude.
Circulating water pump chamber 1 also can be located in motor 3 bodies, to dwindle the volume of whole electric pump.Adopt coil pipe type also circulating water can be cooled off by one section circulating pipe in the cooling unit 8, install also simpler like this.
Claims (4)
1, a kind of by water-cooled closed motor 3, water pump 7, bearing means 2,4,6,9 discharge electric of forming, it is characterized in that motor 3 connects with circulating water pump chamber 1 through bearing means 2, circulating water pump chamber 1 links to each other through the cooling chamber of circulating pipe 12 with motor 3, the cooling chamber of motor 3 goes out pipe 10 with circulating water and links to each other with circulating water pump chamber 1 with circulating water inlet pipe 11 through cooling unit 8, the bearing means 2 of motor 3 and water pump 7,4,6,9, adopt water-fast lubricant oil and all-sealed structure, and separate with main body, cooling unit is the cylindric of both ends open, is set up in parallel for many rows by the circulating pipe in the cooling unit 8.
2, discharge electric according to claim 1 is characterized in that shaft device 2,4,6,9 is submerged bearing, the water lubrication and the cooling that utilize circulating water pump chamber 1 to extrude.
3, discharge electric according to claim 1 is characterized in that circulating water pump chamber 1 is located in motor 3 bodies.
4,, it is characterized in that by the circulating pipe in the cooling unit 8 be coiled by claim 1 or 2 described discharge electric.
