Technical field
The present invention relates to a kind of Submerged Motor Pumps, the multistage high-lift single suction Submerged Motor Pumps of specifically a kind of impeller three flow direction structures configuration can effectively solve the sealing problem of the high voltage terminal of multistage high-lift (special more than 600 meters) Submerged Motor Pumps.
Background technique
At present, the high-lift Submerged Motor Pumps of employed flame-proof mine all adopts traditional typical structure (the impeller double fluid is to configuration) to manufacture and design under the coal mine.No matter in the main pump room; Still high-lift Submerged Motor Pumps is used in rescue and relief work, in test, using process, the sealing of Submerged Motor Pumps high voltage terminal often occurs and goes wrong easily; Cause seal washer under high pressure, to lose efficacy and outwards leak, even repeatedly repeated disassembled and assembled could solve.
High speed development along with China's national economic development increases energy demand day by day, and the digging amount of the main energy sources coal of China is also increasing, and the coal mine degree of depth is continuing to increase at present, and most of mine is between 200 meters～1200 meters.Along with the increase of coal mine height, use the lift of Submerged Motor Pumps increasingly high under the coal mine, high-lift Submerged Motor Pumps solves the high voltage terminal sealing problem becomes the task of top priority.
Summary of the invention
Technical assignment of the present invention is the deficiency to existing technology, and a kind of multistage high-lift single suction Submerged Motor Pumps of impeller three flow direction structures configuration is provided, and the sealing problem that has solved the electric pump high voltage terminal has fully also prolonged the working life of electric pump greatly.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of multistage high-lift single suction Submerged Motor Pumps of impeller three flow direction structures configuration; This electric pump by impeller configuration and flow to be divided into down, in, last three sections designs; Be respectively Submerged Motor Pumps hypomere, Submerged Motor Pumps stage casing and Submerged Motor Pumps epimere; Be provided with the switching-over stage casing between Submerged Motor Pumps stage casing and the Submerged Motor Pumps epimere, the top of Submerged Motor Pumps epimere is a water exit end;
Said Submerged Motor Pumps hypomere is that the electric pump entrance point adopts the one-level impeller to supply water; This section impeller suction inlet is downward; See from impeller inlet; Blade is rotation counterclockwise, and the axial force that produces during impeller work is directed downwards, and this section impeller outlet is directly supplied water to the Submerged Motor Pumps stage casing by Submerged Motor Pumps stage casing outer flow passage;
Said submersible pump stage casing impeller progression is half of the total progression of submersible pump; This section impeller suction inlet upwards; From impeller inlet; Blade is the clockwise direction rotation; The axial force direction that produces during impeller work upwards; Transmit current by inner flow passage between every grade in this section impeller, change direction through long stage casing then and supply water to the submersible pump epimere by submersible pump stage casing outer flow passage;
Half that said Submerged Motor Pumps epimere impeller progression is the total progression of Submerged Motor Pumps subtracts one; This section impeller suction inlet is downward; See that from impeller inlet blade is rotation counterclockwise, the axial force that produces during impeller work is directed downwards; Transmit current by inner flow passage between every grade in this section impeller, then through water exit end, connect section and discharge.
The multistage high-lift single suction Submerged Motor Pumps of a kind of impeller three flow direction structures of the present invention configuration compared with prior art, the beneficial effect that is produced is:
There are following difference in the multistage high-lift single suction Submerged Motor Pumps of impeller three flow direction structures configuration design of the present invention and the double fluid of traditional typical structure design to its impeller configuration of multistage high-lift single suction Submerged Motor Pumps and structural design:
1) sees from the angle of balancing axial thrust that three flow directions are basic identical to both with double fluid.(upwards with downwards) the impeller progression that produces the direction of axial force equates that all just the position is different.
2) see from the current position of zone of high pressure, Submerged Motor Pumps upper end that three flow directions are different fully to the structural design of impeller configuration with double fluid.The current of its zone of high pressure, electric pump upper end of the multistage high-lift single suction Submerged Motor Pumps of impeller three flow direction structures configuration design are to seal with the O RunddichtringO from each stage casing inner flow passage process, and its each stage casing outer flow passage does not have current and pressure.The double fluid of tradition typical structure design from each stage casing outer flow passage process, is the washer sealing processed with rubber asbestos plate to the current of its zone of high pressure, electric pump upper end of multistage high-lift single suction Submerged Motor Pumps.The O RunddichtringO is different with the sealing effect of the packing ring that rubber asbestos plate is processed, and the sealing load of O RunddichtringO is 10～15 times of sealing load of the packing ring processed of rubber asbestos plate.
It is thus clear that multistage high-lift its design of single suction Submerged Motor Pumps of impeller three flow direction structures configuration design can effectively solve the sealing problem of multistage high-lift single suction Submerged Motor Pumps zone of high pressure.
