Abstract
The utility model discloses an elliptical stream guidance pier of a large-scale vertical pump. The stream guidance pier comprises three parts including a stream guidance cone (1), a stream guidance support pillar (2), and an elliptical bell mouth (3), wherein the stream guidance cone (1) can be fixed on a baseplate of a water absorption pool with anchor bolts, the elliptical bell mouth (3) and the stream guidance cone (1) are connected with the stream guidance support pillar (2), and the upper end opening of the elliptical bell mouth (3) is butted with a pump casing. The elliptical stream guidance pier has the advantages of simple structure, low cost, good stream guidance effect, small water power loss, and high pump efficiency, can be widely applied in large-scale vertical diagonal flow pumps, vertical axial pumps, and vertical major axis pumps, and has excellent economic benefits and social benefits.
Description
Technical field
The utility model relates to a kind of flow guide device, particularly relates to a kind of Ellipticum flow guiding piller of macrotype vertical pump.
Background technique
Vertical pump is widely used in from the priming reservoir vertical installation and pumps medium, and vertical diagonal flow pump, vertical-type axial-flow pump, vertical long shaft pump etc. are arranged.Vertical pump generally adopts single basic cantilever configuration, adopts flat horn mouth 9 water inlets of single circular arc.Because the water pump L/D ratio is big, and have only the immovable point in the basis of installation, so anomalies such as vibration, noise appear in water pump easily, influence the water pump safe operation.Though single circular arc horn mouth is simple in structure, its hydraulic loss is bigger, and pump in the position of priming reservoir and responsive to the size matching ratio of priming reservoir, generally only is adapted to medium and small pump.For magna pump (bore is greater than 1 meter), though also adopting single circular arc horn mouth at present, but suck whirlpool, whirlpool and cycle stream under water for preventing to produce air, around must be in the priming reservoir and base plate cement be set prevent whirlpool wall and baffle 10, to increase depth of immersion simultaneously, so just cause the priming reservoir cutting depth to increase, increased civil engineering cost greatly.
The model utility content
Technical problem to be solved in the utility model provides around a kind of flow guide device and the priming reservoir and water pump import bottom need not be provided with the Ellipticum flow guiding piller of macrotype vertical pump that cement is prevented whirlpool wall and baffle.
For solving the problems of the technologies described above, the Ellipticum flow guiding piller of macrotype vertical pump that the utility model provides, form by water conservancy diversion cone, water conservancy diversion supporting post and elliptical horn mouth three parts, described water conservancy diversion cone is fixed on the base plate of priming reservoir with stone bolt, connect with described water conservancy diversion supporting post between described elliptical horn mouth and the described water conservancy diversion cone, described elliptical horn mouth upper end-hole is docked with pump case.
The water conservancy diversion pier by metal integral casting or divide half casting back with bolt closing.Described elliptical horn shape of the mouth as one speaks line is an elliptic curve, and major axis and minor axis ratio are 2: 1.Described water conservancy diversion cone molded lines is a circular curve, and requires water inlet evenly to increase along the journey flow velocity.But described water conservancy diversion supporting post molded lines is for eating the Paderewski aerofoil profile, totally four uniform.
During the water pump maintenance, pump can be taken out parts and can extract out in pump case under the situation of not dismantling pump case and oval water conservancy diversion pier.
The oval water conservancy diversion pier of employing technique scheme compared with prior art has following advantage:
1), water pump water inlet can not produce air and suck whirlpool, whirlpool and cycle stream under water, improved the water inlet fluidised form, reduced hydraulic loss, improved pump efficiency.
2), adopt metal casting, though increased the water pump cost, around the priming reservoir and base plate cement needn't be set prevent whirlpool wall and baffle, saved civil engineering cost.Simultaneously, owing to the improvement of fluidised form, hydraulic loss reduces, and reduced the depth of immersion that water pump needs, thereby the priming reservoir cutting depth reduces, and has saved civil engineering cost equally, so water pump and the still reduction greatly of the whole cost of civil engineering.
3), pump case is fixed on the oval water conservancy diversion pier, avoided the low-frequency vibration of single basic cantilever pump and rocks, and guaranteed the safe operation and the long lifetime of water pump.
In sum, the utility model is a kind of simple in structure, cost is low, water conservancy diversion is effective Ellipticum flow guiding piller of macrotype vertical pump.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2 and Fig. 3, oval water conservancy diversion pier by the metal integral casting or divide half casting back with bolt closing, it is made up of water conservancy diversion cone 1, water conservancy diversion supporting post 2 and elliptical horn mouth 3 three parts, water conservancy diversion cone 1 can be fixed on the priming reservoir base plate 8 with stone bolt 7, connect with water conservancy diversion supporting post 2 between elliptical horn mouth 3 and the water conservancy diversion cone 1, elliptical horn mouth 3 upper end-hole are docked with pump case 4.Elliptical horn mouth 3 molded lines are elliptic curve, and major axis and minor axis ratio are 2: 1.But water conservancy diversion supporting post 2 molded lines are for eating the Paderewski aerofoil profile, totally four uniform.Water conservancy diversion cone 1 molded lines is a circular curve, and requires water inlet evenly to increase along the journey flow velocity.
During the water pump assembling, pump case 4 is inserted in the groove of elliptical horn mouth 3, and circumference is fixing with bolt 5.Oval water conservancy diversion pier is fixed on the priming reservoir base plate 8 with stone bolt 7.During the water pump maintenance, pump can be taken out parts 6 and can extract out in pump case under the situation of not dismantling pump case and oval water conservancy diversion pier.
Adopt the utility model to describe the oval water conservancy diversion pier of content design, manufacturing, be used on the large-scale vertical diagonal pumps transformation project of 600MW thermal power plant bore 1800mm, after tested, import is decreased and has been reduced by 54%, pump efficiency has improved 2.3%, simultaneously significantly reduce the water pump vibration, obtained good economic benefits.
Oval water conservancy diversion pier structure of the present utility model is simple, cost is low, water conservancy diversion is effective, hydraulic loss is little, pump efficiency is high, can extensively be used on large-scale vertical diagonal pumps, vertical-type axial-flow pump and the vertical long shaft pump, has good economic benefits and social benefit.
Personnel in the present technique field should be realized that; the foregoing description is not with the qualification of the present utility model of opposing; as long as in connotation scope of the present utility model, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
