Abstract
The utility model relates to a low-pulse paper pulp pump for transmitting paper pulp in paper-making industry, which comprises a pump body, an impeller, an impeller separator plate, an auxiliary impeller, a pump cover, a shaft, etc., wherein one end of the shaft of the utility model is in a bearing body and is supported by a bearing, and the other end is in the pump body and is orderly provided with the impeller, the impeller separator plate, the auxiliary impeller and the pump cover. The utility model designs a sealing ring between the shaft and the pump cover into a combined seal formed by combining a labium-shaped sealing ring and a Y-shaped sealing ring; impeller blades of the impeller are designed into impeller blades which are staggered and uniformly distributed on an upper and a lower layers. The sealing ring of the utility model bears less pressure, the abrasion is small, and the service life is long; the sealing performance is good at the moment of starting and in parking, pulse generated by the impeller of the utility model is small and water attack resistant, and the pulp coating uniformity of the front part of a net is made to be good.
Description
One, technical field:
The utility model relates to centrifugal pump, particularly relates to be used for the centrifugal pump that paper industry is carried paper pulp.
Two, background technique:
Existing centrifugal pump has multiple seal form.And dynamic seal wherein is fit to contain the medium of carrying various slurries and SS being arranged, and the parking sealer of dynamic seal generally is divided into three kinds, and a kind of is from freeing parking sealer; Its reliability is relatively poor, and another kind is outer control type parking sealer; Its sealability is reliable, but complex structure, the manufacture cost height; The third is a rotary shaft lip seal, and it is low that pressure is born in its lip-type packing, and sub-propeller seals when pump operation, thereby is easy to generate leakage when high-head pump and startup moment and parking.
The impeller of its centrifugal pump mainly contains centrifugal half-opened impeller, centrifugal multichannel impeller, two blade impeller etc., and these impeller blade numbers are fewer, generally have only the 3-6 sheet, its hydraulic efficiency is lower, can only reach 70% at most, its pulse is big, and starching is not used before not being suitable for netting.
Three, technology contents
Order of the present utility model ground is exactly at above-mentioned shortcoming, provide a kind of when starting moment and stopping good seal performance, and the number of blade of impeller is more, pulse is little, be suitable for netting before the low pulse stock pump that uses of starching.
The technological scheme of the utility model number is realized by following scheme:
The utility model includes the pump housing (1), impeller (3), impeller dividing plate (4), sub-propeller (5), axle (12), pump cover (6), one end of axle (12) supports with bearing in bearing support (9), the other end is in the pump housing (1) and impeller (3), impeller dividing plate (4), sub-propeller (5) are housed successively, and between pump cover (6) and the axle (12) is combination seal (10); The number of blade of impeller is more than 6.
Its combination seal (10) is made up of lip-type packing (10-1) and y-type seal ring (10-2), or is made up of lip-type packing (10-1) and U RunddichtringO (10-2).The blade of its impeller (3) is that upper strata blade (3-1) and lower leave (3-2) are double-layer staggered uniform.
The utility model has the advantages that:
1, combined seal ring of the present utility model is by after lip-type packing and the y-type seal ring combination, its y-type seal ring does not bear pressure when operation, wearing and tearing seldom, increased working life, when starting moment and stopping, can play good sealing effect, and lip-type packing can prevent that air from entering pump chamber and reaching watertight perfect sealing effect.
2, impeller of the present utility model has adopted the staggered pulsation that impeller is produced after uniform of upper strata blade and lower floor's leaf to reduce more than one times, thereby has reduced pulsation and water attack, makes before the net all degree of starching better.
Four: description of drawings:
Accompanying drawing 1, be the utility model structural representation
Accompanying drawing 2, be the utility model sealed structural representation
Accompanying drawing 3, be the utility model blade wheel structure figure
Accompanying drawing 4, be the sectional view of accompanying drawing 3
Five, embodiment:
Seal ring (2) is arranged in Fig. 1 middle pump body (1), one end of axle (12) supports with bearing in bearing support (9), the other end is in the pump housing (1), on the axle (12) impeller (3), impeller dividing plate (4), sub-propeller (5), pump cover (6) are housed successively, between pump cover (6) and the axle (12) combination seal (10) is housed, a sealing cover (7) is housed on the pump cover (6), and the bottom of bearing support (9) is connected with a underframe (11).
Among Fig. 2: the combination seal that two lip-type packings (10-1) and y-shaped ring (10-2) composition are housed between sub-propeller (5), pump cover (6), axle (12) and the pump cover (6) is housed on the axle (12), grease seal glue (10-3) is arranged in the lip-type packing (10-2).Among Fig. 3: lower leave (3-2), back blade (3-3) are arranged on wheel hub (3-7) and the back shroud (3-6), inter panel (3-5) is arranged on lower leave (3-2), front shroud (3-4) is arranged on the upper strata blade (3-1), equalizing orifice (3-8) is arranged on the back shroud (3-6).
Claims (3)
1, a kind of low pulse pulp pump, include the pump housing (1), impeller (3), impeller dividing plate (4), sub-propeller (5), axle (12), pump cover (6), one end of axle (12) supports with bearing in bearing support (9), the other end is in the pump housing and impeller (3), impeller dividing plate (4), sub-propeller (5), pump cover (6) are housed successively, it is characterized in that: the combination seal (10) between pump cover (6) and the axle (12) is the combination seal (10) of lip seal figure (10-1) and y-type seal ring (10-2) composition; The number of blade of impeller (3) is more than 6.
2, low pulse pulp pump according to claim 1 is characterized in that: combination seal (10) is made up of lip-type packing (10-1) and y-type seal ring (10-2) or is made up of lip-type packing (10-1) and U RunddichtringO (10-2).
3, low pulse pulp pump according to claim 1 is characterized in that: the blade of impeller (3) is that upper strata blade (3-1) and lower leave (3-2) layer are staggered uniform.
