Abstract
The utility model discloses a pump body of a pipeline pump, which comprises a bottom plate and a shell body arranged above the bottom plate, wherein the bottom plate and the shell body are cast into a whole; an impeller cavity is arranged in the shell body, a water inlet arranged at the right end of the shell body is communicated with the impeller cavity through a ring-shaped water inlet flow channel, and a water baffle is arranged at the end of the water inlet flow channel; a water outlet communicated with the impeller cavity is arranged at the left end of the shell body, and the outer wall of the shell body at the positions of the water inlet and the water outlet is provided with a plurality of streamline reinforcing ribs. As the pump body adopts a ring-shaped sucking flow channel, the NPSH (net positive suction head) of the pump is reduced; in this case, the installing height of the pump is increased. In addition, as the water baffle is designed at the inner part of a suction chamber of the pump body, liquid entering an impeller can be more uniform and losses can be lower; in this case, the efficiency of the pump is increased. As the pump body and the bottom plate are designed into a whole, the pump is more compact in structure and more beautiful in appearance; meanwhile, the cost for processing the bottom plate is cancelled and materials are saved; moreover, as a part is reduced, the standardization degree is higher and obvious economic benefits can be created.
Description
Technical field:
The utility model relates to one step single sucking vertical centrifugal pump field, relates in particular to a kind of pump housing of pipeline mounted pump.
Background technique:
Be extensive use of one step single sucking vertical centrifugal formula pipe pressurizing pump in fields such as cooling system, heating, water treatment, chemical industry.The pipeline mounted pump pump body structure has following characteristics in the market: one, most of pump housings suck runner and adopt the bent-tube boiler structure, just as on the pump suction pipe road, having increased a bend pipe, therefore liquid loses bigger from pump housing flange to the impeller inlet process, cause the NPSH variation, cavitation easily takes place in pump.Two, the pump housing separates with base plate, and the pump housing relies on three root posts to support, and pump housing wall thickness can be in uneven thickness, when casting easily in supporting post the position form casting defect, as pore, sand holes etc., especially more difficult casting when the casting stainless steel pump housing causes finished casting rate very low.The pump housing and base plate rely on following three Bolt Connection of base plate, and bolt is below base plate, so on-the-spot can't check the bolt looseness that whether may cause because of the pump long-play, this structure pump housing center is high whole higher, whole pump center of gravity also improves thereupon, and above reason may make pump produce vibration, poor stability when operation.Three, the reinforcing rib design of the pump housing does not meet streamlinedly, and stressing conditions is not that fine shape is not attractive in appearance yet.
The utility model is improved to the superior annular water inlet flow channel of hydraulic performance with the elbow structure that original pump housing water inlet flow channel (suction runner) adopts, every pump suction chamber area all passes through strict designing and calculating, and in the indoor design of the pump housing suction chamber water-stop sheet, make the liquid that enters impeller more even, lose littler, thereby also improved the efficient of water pump.The pump housing and back-plane design is as a whole, make pump structure compacter, reduced the center height of pump simultaneously, stone bolt directly connected the pump housing when pump used at the scene, and it is more steady that operation is got up, and reduced the probability that vibration produces to a great extent.The pump housing has designed fairshaped stiffening rib, and structure is attractive in appearance, and intensity is higher.
The model utility content:
The purpose of this utility model provides a kind of pump housing of pipeline mounted pump, be applicable to that pumping physicochemical properties is similar to the pipeline mounted pump of water and pumps the pump housing among the vertical pumps such as pipeline mounted pump of Korrosionsmedium, ensure that the riser pump is under the prerequisite of normal operation, make that net positive suction head is little, efficient is high, operation is steady more, pump housing intensity height, compact structure, the riser centrifugal pump body of beautiful shape.
The technical solution of the utility model is as follows:
The pump housing of pipeline mounted pump, comprise base plate, housing, it is characterized in that: the housing cast solid of described base plate and top, be provided with impeller cavity in the described housing, the right-hand member of described housing is provided with water intake, described water intake communicates with the water inlet flow channel of described impeller cavity by annular, and described water inlet flow channel end is provided with water-stop sheet; The left end of described housing is provided with the water outlet that is connected with described impeller cavity.
The pump housing of described pipeline mounted pump is characterized in that: the outer wall of described housing is positioned at water intake, the water outlet place is provided with several fairshaped stiffening ribs.
The beneficial effects of the utility model are:
The utility model adopts the water inlet flow channel of annular, make NPSH reduce (promptly having reduced the loss of pump housing flange liquid energy in the impeller eye process to a great extent), thereby improved the setting height(from bottom) of pump, can be directly installed on the pipeline as other pipeline mounted pump and use, also can suct or the abominable situation of suction condition under use; And in the indoor design of the pump housing suction chamber water-stop sheet, make the liquid that enters impeller more even, lose littler, thereby also improved the efficient of water pump; The pump housing and back-plane design are to make pump structure compacter, attractive in appearance after the one.Also omitted simultaneously the expense of processing base plate, saved material, owing to reduced by a part, there is tangible economic benefit in institute so that standardization level is higher.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The pump housing of pipeline mounted pump comprises base plate 1, housing 2, housing 2 cast solids of base plate 1 and top, be provided with impeller cavity 3 in the housing 2, the right-hand member of housing 2 is provided with water intake 4, and water intake 4 communicates with the water inlet flow channel 5 of described impeller cavity 3 by annular, and water inlet flow channel 5 ends are provided with water-stop sheet 6; The left end of housing 2 is provided with the water outlet 7 that is connected with described impeller cavity 3, and the outer wall of housing 2 is positioned at water intake 4, water outlet 7 places are provided with several fairshaped stiffening ribs 8.
