Abstract
The utility model relates to an annular water sucking chamber of a vertical pipeline pump. The annular water sucking chamber comprises a water sucking chamber and a clapboard, wherein the water outlet of the water sucking chamber is dead against the inlet of an impeller; the clapboard comprises a clapboard top and two clapboard transition sections positioned at two sides of the clapboard top; the clapboard top is in a taper shape corresponding to the water flowing direction; and the clapboard transition sections are arc surfaces which are respectively connected with the two side walls of the water sucking chamber and the clapboard top. According to the annular water sucking chamber, the technical problem of vortex loss due to the adoption of a vertical clapboard in the existing water sucking chamber of the vertical pipeline pump is solved and the hydraulic efficiency is improved.
Description
Technical field
The utility model relates to a kind of suction chamber structure of riser pump.
Background technique
In the riser pump, suction chamber adopts annular suction chamber usually, and is as depicted in figs. 1 and 2, and flow enters into annular space with the form of sudden enlargement, changes 90 ° with shrink form then and bends, and gets into impeller vertically.Therefore the speed of first half entering impeller is greater than Lower Half.Because Lower Half liquid comes together in the middle of two side direction, can occur rotatablely moving.So annular suction chamber water velocity skewness.
For prevent that Lower Half liquid from bumping when come together two side direction centre, generally be the straight baffle that width H=6～10 are set in annular suction chamber bottom, as shown in Figure 3.But when adopting the suction chamber work of straight baffle, form easily when liquid vertically clashes into dividing plate and rotatablely move and produce the whirlpool loss, thereby reduce hydraulic efficiency.
Summary of the invention
The object of the invention provides a kind of riser pump annular suction chamber that adopts the flowing water type dividing plate, and it has solved existing riser pump suction chamber and has produced the technical problem of whirlpool loss because of adopting straight baffle.
Technical solution of the present invention is:
A kind of riser pump annular suction chamber comprises suction chamber 4, dividing plate 5, and the water outlet 2 of said suction chamber 4 is over against impeller eye 10, and its special way is: said dividing plate 5 comprises dividing plate top and the dividing plate changeover portion that is positioned at both sides, dividing plate top; Said dividing plate top is the taper of corresponding water (flow) direction, and said dividing plate changeover portion is for connecting the arc surface at suction chamber both sides sidewall and dividing plate top respectively.
The angle of taper A=30 at aforementioned barriers top～40 °.
The aforementioned barriers top is positioned at half place of impeller eye radius.
Radius of arc R=45～60 of aforementioned barriers changeover portion.
Advantage of the present invention: the utility model adopts the flowing water type dividing plate in annular suction chamber Lower Half, forms when having eliminated liquid and vertically clashing into dividing plate to rotatablely move and produce the whirlpool loss, thereby improves hydraulic efficiency.

Embodiment
Like Fig. 4 and shown in Figure 5, riser pump annular suction chamber of the present invention comprises suction chamber 4 and dividing plate 5.Dividing plate 5 comprises dividing plate top 12 and the dividing plate changeover portion 13 that is positioned at both sides, dividing plate top; The dividing plate top is the taper of corresponding water (flow) direction, and preferably the dividing plate top is positioned at half place of impeller eye radius; The angle of taper A=30 at dividing plate top～40 °; The dividing plate changeover portion is the arc surface that connects suction chamber both sides sidewall and dividing plate top respectively, radius of arc R=45～60, and optimum radius is 50.The water inlet place of suction chamber 4 is provided with branch overflow 1; Current are divided into left and right sides two-way by a minute overflow and get into annular suction chamber; Flow out through 90 ° of the water outlets 2 of turning after the guiding of dividing plate again from annular suction chamber, get into water outlet over against impeller eye 10, through impeller acting back entering pumping chamber 9.
