Background technique
At present, the flame-proof mine high head electric submergible pump that underground coal mine uses all adopts traditional typical structure (impeller double fluid is to configuration) to manufacture and design.No matter in main pump room, or rescue and relief work high head electric submergible pump, in test, using process, often occurs that the sealing of Submerged Motor Pumps high voltage terminal easily goes wrong, cause seal washer to lose efficacy at elevated pressures outwards to leak, even repeatedly repeated disassembled and assembled could solve.
Along with the high speed development of China's national economic development, increasingly increase energy demand, the digging amount of the main energy sources coal of China is also in increase, and the current coal mine degree of depth is continuing to increase, and most of mine is between 200 meters ~ 1200 meters.Along with the increase of coal mine height, underground coal mine uses the lift of Submerged Motor Pumps more and more higher, and high head electric submergible pump solves high voltage terminal sealing problem becomes the task of top priority.
Summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, the multistage high-lift single single suction Submerged Motor Pumps providing a kind of impeller three flow direction structure to configure, and completely solves the sealing problem of electric pump high voltage terminal and substantially prolongs working life of electric pump.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of multistage high-lift single single suction Submerged Motor Pumps of impeller three flow direction structure configuration, this electric pump by impeller configuration and flow to be divided under, in, upper three sections of designs, be respectively Submerged Motor Pumps hypomere, Submerged Motor Pumps stage casing and Submerged Motor Pumps epimere, be provided with commutation stage casing between Submerged Motor Pumps stage casing and Submerged Motor Pumps epimere, the top of Submerged Motor Pumps epimere is water exit end;
Described Submerged Motor Pumps hypomere and electric pump entrance point adopt one stage impeller to supply water, this section of impeller suction inlet is downward, from impeller inlet, blade is counterclockwise rotate, the axial force direction produced during impeller work is downward, and this section of impeller outlet is directly supplied water to Submerged Motor Pumps stage casing by Submerged Motor Pumps stage casing outer flow passage;
Described Submerged Motor Pumps stage casing impeller progression is the half of the total progression of Submerged Motor Pumps, this section of impeller suction inlet upwards, from impeller inlet, blade is that clockwise direction rotates, the axial force direction produced during impeller work upwards, transmit current by inner flow passage between every grade, this section of impeller, then supplied water to Submerged Motor Pumps epimere by Submerged Motor Pumps stage casing outer flow passage through change direction, long stage casing;
Described Submerged Motor Pumps epimere impeller progression is that the half of the total progression of Submerged Motor Pumps subtracts one, this section of impeller suction inlet is downward, from impeller inlet, blade is counterclockwise rotate, the axial force direction produced during impeller work is downward, transmit current by inner flow passage between every grade, this section of impeller, then discharge through water exit end, connection section.
Compared with prior art, the beneficial effect produced is the multistage high-lift single single suction Submerged Motor Pumps of a kind of impeller three flow direction structure configuration of the present invention:
The double fluid of the multistage high-lift single single suction Submerged Motor Pumps that impeller three flow direction structure configuration of the present invention designs and traditional Typical Structure Design configures to its impeller of multistage high-lift single single suction Submerged Motor Pumps and structural design exists following difference:
1) from the angle of balancing axial thrust, three flow directions are substantially identical to both with double fluid.(up and down) impeller progression producing the direction of axial force is all equal, and just position is different.
2) from the current position of zone of high pressure, Submerged Motor Pumps upper end, the structural design difference completely that three flow directions and double fluid configure to impeller.The current of its zone of high pressure, electric pump upper end of multistage high-lift single single suction Submerged Motor Pumps of impeller three flow direction structure configuration design, from each stage casing inner flow passage process, are that its each stage casing outer flow passage does not have current and pressure with the sealing of O RunddichtringO.The double fluid of tradition Typical Structure Design, to the current of its zone of high pressure, electric pump upper end of multistage high-lift single single suction Submerged Motor Pumps from each stage casing outer flow passage process, is the washer sealing made with rubber asbestos plate.The sealing effect of the packing ring that O RunddichtringO and rubber asbestos plate are made is different, and the sealing load of O RunddichtringO is 10 ~ 15 times of the sealing load of the packing ring that rubber asbestos plate is made.
Its design of multistage high-lift single single suction Submerged Motor Pumps of visible impeller three flow direction structure configuration design effectively can solve the sealing problem of multistage high-lift single single suction Submerged Motor Pumps zone of high pressure.
