In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of Double-suction submerged pump, including motor, shaft coupling, pump shaft, holder, sliding bearing, pump cover, impeller, axle cap, the pump housing
And filter screen；The impeller of the Double-suction submerged pump is the double-suction type structure being arranged symmetrically, and fan is equipped at the choma of the impeller both sides
Palace sealing structure.
Preferably, the lower part of the holder offers equally distributed window, and the window constitutes the Double-suction submerged pump
Upper suction side water inlet.
Preferably, the pump cover side of the Double-suction submerged pump is equipped with sliding bearing, and the sliding bearing is by the pump cover side
Polytetrafluoroethylene (PTFE) bearing stationary ring and the pump shaft on Ceramic shaft sleeve rotating ring composition.
Preferably, the axial side lower part of the pump housing is equipped with filter screen, and the filter screen is set to the lower suction of the impeller
Enter side water inlet.
Preferably, the pump shaft is made of the stainless steel hexagonal bar of external coating plastic.
Preferably, labyrinth seal structure is equipped at the both sides choma of the impeller, the impeller both sides choma position uses
Labyrinth seal improves the efficiency of pump for reducing leakage.
Preferably, the labyrinth seal structure is by the recessed of the pump cover and the boss of pump housing side and impeller both sides choma
Slot, which staggeredly coordinates, to be constituted.
Using above-mentioned technical proposal, which is intended to provide a kind of Double-suction submerged pump to the user, the Double-suction submerged pump
Decoration structure features simple design is reasonable, simple for production, and impeller is the double suction structure being arranged symmetrically, axial force when Double-suction submerged pump being made to work
It is effectively balanced (almost without axial force), impeller both sides choma position uses labyrinth seal, and internal capacity loss is small, whole
Engine efficiency is high, and (20%) at least more energy saving than common submerged pump, advantageously reduces energy consumption, and the service life and reliability of complete machine are also big
Amplitude improves.
Description of the drawings
Fig. 1 is the organigram of Double-suction submerged pump of the present invention；
Fig. 2 is the organigram of impeller port ring position labyrinth gland in the present invention.
Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but does not constitute limitation of the invention.In addition, disclosed below
The each embodiment of the present invention in involved technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1, the present invention Double-suction submerged pump organigram in, the Double-suction submerged pump include motor 1,
Shaft coupling 2, pump shaft 3, holder 4, sliding bearing 5, pump cover 6, impeller 7, axle cap 8, the pump housing 9 and filter screen 10 etc..Under the double suction liquid
Pump is double-suction type structure.It should be understood that the impeller 7 is the double-suction type structure being arranged symmetrically.
It should be understood that the lower part of the holder 4 is provided with equally distributed window, which constitutes the upper suction of Double-suction submerged pump
Enter side water inlet；6 side of pump cover be equipped with sliding bearing 5, the sliding bearing 5 by 6 side of pump cover polytetrafluoroethylene (PTFE) bearing stationary ring and
Ceramic shaft sleeve rotating ring composition on pump shaft 3；The axial side lower part of the pump housing 9 is equipped with filter screen 10, which is set to leaf
The lower suction side water inlet of wheel 7；The pump shaft 3 is made of the stainless steel hexagonal bar of external coating plastic；
It should be understood that being equipped with labyrinth seal structure at the both sides choma of the impeller 7.It is revealed for reducing, improves pump efficiency
Rate.
Fig. 2 shows Double-suction submerged pump impeller port ring position labyrinth gland organigram in, above-mentioned leaf
The ring portion position suitable for reading of wheel 7 is equipped with labyrinth gland 71, and lower choma position is equipped with maze device 72, by 9 side of pump cover 6 and the pump housing
Boss and impeller 7 choma at groove staggeredly coordinate and constitute labyrinth.
What the operation principle of the Double-suction submerged pump of the present invention was realized in：Motor 1 is fixed on pump by the drive of shaft coupling 2
7 high speed rotation of impeller on axis 3, above fluid flowed into from the window of 4 lower part of holder of Double-suction submerged pump, through the middle part of pump cover 6
Opening enter impeller 7, below fluid enter impeller 7 from axial side-entrance of the filter screen 10 through the pump housing 9 of bottom, with impeller 7
Centrifugal movement is done in rotation, from scroll casing shape runner discharge of 7 outer rim of impeller through the pump housing 9.
