Abstract
The utility model provides a high -efficient large -scale horizontal split case pump, the pump body of this pump of, pump cover inner wall are equipped with the cavity of the weight that alleviates the pump, have alleviateed the weight of pump, have reduced manufacturing cost, the transport of being convenient for, the sealing ring adopts sealed effectual two O type sealing ring structure, and its structure sealing effect is better, and liquid is little to erodeing of the pump body, the pump body and pump cover assembly back form closed runner in the impeller exit, reduce the phegmal reflux, improved the hydraulic efficiency of pump, the pump body and pump cover are equipped with the radial strengthening rib of circumference outward, have strengthened the intensity and the rigidity of pump body pump cover, and the appearance of pump is more pleasing to the eye, impeller both sides blade staggered arrangement has effectively reduced the low frequency pulse, impeller suction inlet department adopts starting taper formula sealing ring, and liquid does not have the striking and gets into the impeller, reduces the loss of impeller import department energy, the asymmetric flow distribution plate structure of water inlet channel adoption of pump body water inlet department makes the pump suction chamber top and bottom aqccumulated excess and the bending of runner form the complementation, can guarantee that the flow field of flow distribution plate both sides distributes approximate the samely.
Description
One, technical field
The utility model relates to mechanical engineering pump class technical field, is specifically to drive centrifugal pump in a kind of high-efficiency large horizontal type level.
Two, background technique
Open the application of centrifugal pump widely in current Chinese large-sized horizontal type level, but the pump quality of generally reacting this type is in actual applications large, difficult.Because some structural design is undesirable, cause the water conservancy efficiency of its poor performance, pump low, working life is short.
Three, summary of the invention
In order to overcome the deficiency of above-mentioned technology, the purpose of this utility model is to provide in a kind of high-efficiency large horizontal type level and drives centrifugal pump, makes its quality light, long service life, and the efficiency that improve pump.
Realizing the technological scheme that the purpose of this utility model adopts is: drive centrifugal pump in this high-efficiency large horizontal type level and comprise pump shaft, impeller, pump cover, seal ring, the pump housing, seal ring; The described pump housing and the inwall of pump cover are provided with the cavity of the weight alleviating pump, seal ring adopts two O RunddichtringO structures of good sealing effect, closed runner is formed at impeller outlet place after the described pump housing and pump cover assembling, circumference radial reinforced rib is provided with outside the pump housing and pump cover, impeller both sides blade stagger is arranged, impeller suction inlet place adopts starting taper formula seal ring, and the water inlet flow channel of pump housing water inlet adopts asymmetric manifold structure.
The utility model advantage is compared with prior art:
1, significantly reduce the weight of pump, reduce manufacture cost and be convenient to carrying;
2, between seal ring and the pump housing, no liquid washes away phenomenon, and sealing effect is better;
3, in the spiral case that formed of closed runner, capacity of reflux is little, and the hydraulic efficiency of pump is higher;
4, impeller both sides blade stagger is arranged, low frequency pulsating is less, effectively reduces low-frequency pulse;
5, starting taper formula seal ring, makes liquid enter impeller without shock, decreases energy loss, improves the cavitation performance of impeller inlet;
6, the stiffening rib increased enhances the strength and stiffness of pump housing pump cover, the profile also better appearance of such pump;
Four, accompanying drawing explanation

Fig. 2 is the partial enlarged drawing at Fig. 1 I position.
Fig. 3 is the double-entry impeller both sides blade stagger layout figure driving centrifugal pump in the utility model.
Fig. 4 is pump cover circumference radial reinforced rib structural representation.
In figure: 1. impeller, 2. pump cover, 3. seal ring, the 4. pump housing, 5. seal ring O RunddichtringO, 7. blade, 8. flow distribution plate, 9. radial reinforced rib.
Five, embodiment
In the accompanying drawings, drive centrifugal pump in a kind of high-efficiency large horizontal type level of the utility model, this pump comprises pump shaft, impeller, pump cover, seal ring, the pump housing, seal ring; The described pump housing 4 and the inwall of pump cover 2 are provided with cavity 13 and the cavity 12 of the weight alleviating pump, and cavity can alleviate the weight of pump, reduce manufacture cost and are convenient to carrying; Seal ring 3 adopts two O RunddichtringO 5 structures of good sealing effect, and its sealing structure effect is better, and liquid is little to washing away of the pump housing; Form closed runner 10 at impeller outlet place after the described pump housing 4 and pump cover 2 assemble, its benefit reduces capacity of reflux, improves the hydraulic efficiency of pump; Be provided with circumference radial reinforced rib 9 outside the pump housing 4 and pump cover 2, enhance the strength and stiffness of pump housing pump cover, make the profile better appearance of pump; Impeller both sides blade 7 interlaced arrangement, effectively reduces low-frequency pulse; Impeller 2 suction inlet place adopts starting taper formula seal ring 11, and liquid enters impeller without shock, reduces the loss of impeller inlet place energy; The water inlet flow channel of pump housing water inlet adopts asymmetric flow distribution plate 8 structure, and what make pump suction chamber top and bottom product moment and runner is bent to form complementation, can ensure that the Flow Field Distribution of flow distribution plate both sides is similar to identical.
