Abstract
The utility model relates to a pump case of a double-suction pump with a novel structure, which comprises a pump body, a delivery chamber, a suction chamber, a sealing ring and a sealing body. The pump case is characterized in that an annular groove is arranged on the inner wall of the pump body between the delivery chamber and the suction chamber, so that a positioning seam is formed, the sealing ring is fixedly embedded in the positioning seam, and the sealing body is integrally arranged at a position, close to an outlet of the pump body, of the delivery chamber. The pump case has the advantages that the pump case is simple in structure, higher in processing precision and firmer in positioning, and realizes safe and abrasion-free running better; and the pump case and the sealing body are integrated, integral casting is realized, requirements on matching between the pump case and the sealing body are reduced, and the problem of leakage due to insufficient processing precision is resolved.
Description
Technical field
The utility model relates to double suction pump, particularly a kind of pump case of new structure double suction pump.
Background technique
Along with double suction pump is used widely, the problem of its appearance is also more and more.At first, the pump case of existing double suction pump and seal ring are through the locating stud location, and Location accuracy is lower, cause the wearing and tearing of impeller and seal ring very serious; Secondly, through the O-ring seals sealing, often because of machining accuracy causes sealing part to be leaked inadequately, the situation of scrapping of part is very serious between pump case and the seal; At last, existing double suction pump pump case and all only cast a positioning spigot above the bearing support, Location accuracy is difficult to guarantee that if machining accuracy is defective, there is deviation the location, will produce vibration during the bearing operation, causes to reduce greatly the working life of bearing; Also can make whole water pump produce vibration when serious.More than any situation occur, must the termination of pumping maintenance, change component, have very big potential safety hazard.
The model utility content
The utility model is exactly the deficiency that overcomes existing technology, and a kind of pump case of new structure double suction pump is provided.
The technological scheme of the utility model is achieved in that a kind of pump case of new structure double suction pump; Comprise: the pump housing, delivery chamber, suction chamber, seal ring and seal; It is characterized in that: on the pump housing inwall between delivery chamber and the suction chamber, offer circular groove, form the said seal ring of confession and be embedded fixing positioning spigot; Be wholely set said seal at delivery chamber near pump housing outlet port.
The advantage of the utility model: simple in structure, machining accuracy is higher, locatees more firmly, has better realized safe nothing wearing and tearing running; Pump case and two component of seal are united two into one, realize cast inblock, reduced the cooperation between part, solved because the not enough leakage problem that produces of machining accuracy.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
See also Fig. 2, Fig. 2 is the structural representation of the utility model.A kind of pump case of new structure double suction pump shown in the figure; Comprise: the pump housing 1, delivery chamber 3, suction chamber 2, seal ring and seal 4; It is characterized in that: on the pump housing inwall between delivery chamber and the suction chamber, offer circular groove 5, form the said seal ring of confession and be embedded fixing positioning spigot, adopt the seam location; The location is more firm during assembling, has realized safe nothing wearing and tearing running; Be wholely set said seal at delivery chamber near pump housing outlet port, realized cast inblock, whole processing has reduced the fitted seal problem between the part; On the pump case, all cast with bearing support and cooperate localization part, upper and lower positioning spigot machines with the boring machine one-pass, and double stopper positioning bearing body is located more accurately, and the operation of double suction pump is more stable.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
