Abstract
A direct-discharge volute submerged pump comprises a pump body (9), a pump cover (7), and an impeller (8). The direct-discharge volute submerged pump is characterized in that the pump body is provided with a volute, a first liquid outlet channel (11) and a second outlet channel (13) are symmetrically disposed on two sides of a shaft (14), and medium is driven by the impeller (8) to flow out of an outlet through the first liquid outlet channel (11) and the second outlet channel (13) on two sides of the pump body (9). By the direct-discharge volute submerged pump, the medium is introduced to the outlet through the symmetric liquid outlet channels smoothly, and defects of guide vane type shells are overcome. In addition, the direct-discharge volute submerged pump is easy to cast and examine.
Description
Technical field
The utility model relates to a kind of in line scroll casing type Under Water Pumps that goes out.
Background technique
Under Water Pumps for medium passes in and out vertically when using the one step single sucking impeller, generally all adopts the stator form pump housing of symmetry; The pump case casting difficulty of this form is bigger; Especially at the turning, shell space is narrow and small, the not only difficult measurement of can't testing simultaneously of casting; Often cause the pump type undesirable, so that pump efficiency is low.
Summary of the invention
The purpose of the utility model provides high in line of a kind of efficient and goes out the scroll casing type Under Water Pumps.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is:
A kind of in line scroll casing type Under Water Pumps that goes out; Comprise the pump housing, pump cover, impeller; It is characterized in that: the said pump housing adopts the scroll casing type design; The axle bilateral symmetry is provided with the first fluid runner and the second fluid runner, and medium is through both sides first fluid runner and the second fluid runner flow direction outlet of impeller action along the pump housing.
[0005]Adopt gasket seal between the said pump housing and the pump cover, impeller adopts chuck and impeller nut to carry out secure fixation, and impeller nut and chuck adopt gasket seal, adopts the sealing of O type circle between chuck and the impeller.
Be fixed with axle sleeve on the said axle, between the pump housing and the axle sleeve axle bush be installed.
Said axle sleeve is fixed on the axle, and axle bush is fixed in the pump through interference fit.
Be fixed with removable wear ring on the said pump cover, form the gap with impeller.
The beneficial effect of the utility model is: the design of the scroll casing type pump housing adopts the fluid runner design of symmetry to guide medium into outlet, and transition is even, has avoided the defective of stator form housing, is prone to the casting readily inspection.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, in linely go out the scroll casing type Under Water Pumps and mainly contain the pump housing 9, pump cover 7, impeller 8, support column 15.The pump housing 9 adopts the scroll casing type design, and the both sides first fluid runner 11 and the second fluid runner 13 be symmetry vertically, but the most of radial force of balance.Medium is through both sides first fluid runner 11 and second fluid runner 13 flow direction outlets of impeller 8 effects along the pump housing 9.Both sides fluid runner extends upward, and the sectional area of fluid runner enlarges gradually, to rational position, gets into support column 15 place's runners.Adopt pad 6 sealings between the pump housing 9 and the pump cover 7; Impeller 8 adopts chuck 3 and impeller nut 1 to carry out secure fixation; Impeller nut 1 adopts pad 2 sealings with chuck 3; Adopt 4 sealings of O type circle between chuck 3 and the impeller 8, be fixed with axle sleeve 12 on the said axle 14, between the pump housing 9 and the axle sleeve 12 axle bush 10 is installed.Axle sleeve 12 plays good supporting effect with cooperating of axle bush 10.Be fixed with removable wear ring 5 on the pump cover 7,, guarantee throttling with impeller 8 formation gaps.
Claims (4)
1. one kind in linely goes out the scroll casing type Under Water Pumps; Comprise the pump housing (9), pump cover (7), impeller (8); It is characterized in that: the said pump housing (9) adopts the scroll casing type design; Axle (14) bilateral symmetry is provided with the first fluid runner (11) and the second fluid runner (13), and medium is through both sides first fluid runner (11) and second fluid runner (13) flow direction outlet of impeller (8) effect along the pump housing (9).
2. according to the described in line scroll casing type Under Water Pumps that goes out of claim 1; It is characterized in that: adopt pad (6) sealing between the said pump housing (9) and the pump cover (7); Impeller (8) adopts chuck (3) and impeller nut (1) to fix; Impeller nut (1) adopts pad (2) sealing with chuck (3), adopts O type circle (4) sealing between chuck (3) and the impeller (8).
3. according to the described in line scroll casing type Under Water Pumps that goes out of claim 2, it is characterized in that: be fixed with axle sleeve (12) on the said axle (14), between the pump housing (9) and the axle sleeve (12) axle bush (10) be installed.
4. according to the described in line scroll casing type Under Water Pumps that goes out of claim 1, it is characterized in that: be fixed with removable wear ring (5) on the said pump cover (7).
