Abstract
The utility model relates to a submersible electric pump for removing axial force, which is composed of a pump rotor assembly, a stator assembly, a check valve assembly 15, a coupling assembly 3, a submersible electric machine 2, a flanged disc 14, water pipes 9, 19. The submersible electric pump is characterized in that pump impellers 7 and pump housings 6 are symmetrically and oppositely arranged in the same quantity, an upper connecting section 12 is changed into an upper connecting section 21, and a top section 13 is changed into a top section 20 so as to form the pump with the other performance. The utility model has the advantages of axial force removal, long service life, operational reliability enhancement, simple structure, convenient installation and low cost, and one pump and two parts have the functions of two pumps. The utility model can be widely used for a mine, the water transmission of a sea, a river and a lake, an aquaculture industry, an animal husbandry, a tall building, a mountain, water supply, sewage conveyance, etc.
Description
The utility model belongs to the pump class of diving.
The latent pump that prior art provides all has following deficiency: 1. pump impeller all can produce very big axial force when pump operation, passes to pump shaft and just forms axial force.The axial force that lift and pump sum of series produce thereupon is proportional, and lift is high more, and axial force is big more, and the ability that the bearing that is adopted can bear axial force all has its permitted value surely, when oepration at full load, just reaches working life very soon.Overburdening or fed sheet of a media factor are arranged, just shorten the working life of bearing.Restriction greatly improves constantly the needs of lift, also can make pump group reliability can not get guaranteeing because of operating accidentalia; 2. the submersible motor of the pump group generation heat that is in operation although be in the medium of conveying, has radiating condition preferably, and medium on every side is bordering on state of rest, influences dispersing of heat; 3. the employing series connection balanced type thrust-bearing that has, bearing axial force can double by the single normal rated thrust bearing of force rate, receives certain effect, but its complex structure, difficult assembling.
The object of the present invention is to provide a kind of simple in structure, long service life, reliable, can eliminate the axial force Submerged Motor Pumps.
Technical characterstic of the present invention is to establish connecting section, top section on pump top, in pump body structure, adopts symmetry, pump case, the impeller of quantity such as layout in opposite directions, with the axial force of ballast pump generation in service; At latent motor peripheral hardware tubular catchment covers,, quicken cooling to motor to increase the fed sheet of a media flow velocity.
This elimination axial force Submerged Motor Pumps technical solution, in conjunction with the accompanying drawings 1.The first kind is eliminated axial force Submerged Motor Pumps structural representation and is described further.
This first kind is eliminated the axial force Submerged Motor Pumps as shown in Figure 1, and it is by the pump rotor assembly: form with pump shaft 4, tapered sleeve 10, impeller 7, impeller 7 usefulness tapered sleeves 10 are fixed on the pump shaft 4; Pump stator assembly: by x shape next door in the middle of water inlet joint 5, pump case 6, the cylindrical shape, left and right side is made up of two sorrowful top sections 13 by upper and lower opening about inclined clapboard connecting section 12, cylindrical shape middle part on the termination cylindrical shape on upper and lower opening stage casing 8, the pump, form with bolted on connection between each part, wherein establish water-fast bearing 11 in water inlet joint 5, pump case 6, the stage casing 8, with support rotor; Check valve assembly 15; Form by valve body 16, valve disc bar 17, sphere valve disc 18; Coupling assembly: form by coupling 3, key; The pump rotor assembly places in the pump stator assembly, the coupling assembly connects submersible motor 2 with rotor assembly, water inlet joint 5 and submersible motor 2 peripheral hardware cylindrical shape catchment covers 1, water pipe 9,19 usefulness flange plate 14 screws are anchored on stage casing 8, the top section 13, connect check valve assembly 15 on the top section 13 and assemble.
This second kind is eliminated the axial force Submerged Motor Pumps as shown in Figure 2, the top section 13 that it is just eliminated the first kind in the axial force Submerged Motor Pumps changes two side openings top, no inclined clapboard cylindrical shape middle part section 20 into, and cylindric upward connecting section 12 is changed into last connecting section 21 formations that closed on both sides above the cylindrical shape has water intake.Top section 13,20, the profile of last connecting section 12,21 is identical with installation dimension.
The first kind is eliminated the latent electric pump operation of axial force: after starting submersible motor 2, the rotation of drive pump rotor, water enters the pump hypomere in catchment covers 1, upwards 8 right side end opening water inlet pipes 9 enter top 13 inclined clapboard end openings through the stage casing, because pump impeller 7 is instead adorned, downwards, the 8 left sides water inlet pipe 19 suitable for reading through the stage casing is gone into the output of check valve assembly by top section 13 inclined clapboards are suitable for reading to water in the pump.The second kind is eliminated the operation of axial force Submerged Motor Pumps: after starting submersible motor 2, the rotation of drive pump rotor, water enters the pump hypomere upwards, 8 end openings through the stage casing, water inlet pipe 9 in catchment covers 1, through open top section 20 is arranged, go into the output of check valve assembly, top water is gone in the pump downward from the last connecting section 21 that opening is arranged, and 8 left side is suitable for reading through the stage casing, water inlet pipe 19 is gone into the output of confluxing of check valve assembly.
This elimination axial force Submerged Motor Pumps advantage:
This pump adopt symmetry, arrange in opposite directions, etc. the pump case 6 of quantity, impeller 7, axial force that can ballast pump generation in service, can eliminate in theory is 0, therefore can increase the service life greatly, improves operational reliability;
2. improve the cool condition of submersible motor, strengthened the durability of motor;
3. buy a first kind as the user and eliminate the axial force Submerged Motor Pumps, repurchase top section 20, go up connecting section 21 each one replacing top sections 13, last connecting section 12, can obtain the second kind and eliminate the axial force Submerged Motor Pumps, when if first kind pump duty is Q rice 3/, lift H rice is when then the flow of second kind pump is 2Q rice 3/, lift H/2 rice, promptly buy a pump can push up 2 with.
4. the last connecting section of newly establishing 12,21, top section is 13,20 simple in structure, easy for installation, reliable, cost is low;
5. as in the lake, sea, korneforos use, and need not build pumping plant, adopts floating drum, he can carries at a distance.
This elimination axial force Submerged Motor Pumps can be widely used in that mine, deep-well, Gou He, lake, light, sea-farming, effluent discharge, grassland are herded, high building, high mountain water supply etc., can carry the liquid that is similar to water.
