Description

Deep-well pump blower inlet casing
Technical field
The utility model relates to a kind of deep-well pump blower inlet casing.
Background technique
At present, its guide vane of deep-well pump blower inlet casing adopts cylinder blade (to claim again prismatic blade more, both blade surface was vertical with diversion disk, and blade is single-curvature form), because general deep-well pump many places are in middle higher specific speed scope, vane inlet limit is very wide, its vane inlet flow angle difference, therefore cylinder blade cannot meet its flowing law, causes fluid hydraulic loss in its runner larger.
Conventionally deep-well pump enterprise emphasizes the sand content of fed sheet of a media in the time making specification; but user can be used in deep-well pump in various complex environments conventionally; such as new well well-flushing; its sand content is superelevation pump using scope far away; cause pump within operation very short time; silt particle is gathered in the impeller back side and diversion disk region consequently occurs catching phenomenon more seriously can causing burn-down of electric motor phenomenon.This just requires deep-well pump under the larger environment of sand content, normally to work, and anti-silt particle function just becomes a difficult problem for puzzlement well pump.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above of prior art existence and a kind of deep-well pump blower inlet casing is provided, and guide vane is designed to the twisted blade of double curvature, and flow passage structure meets fluid flowing law, and portion of energy is reclaimed, increase lift of pump, reduce hydraulic loss in guide vane, improve pump efficiency, in addition, set up anti-sand launder, there is sand control and lubricating function, greatly extend the working life of pump, avoid inserts, also reduce cost of material.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: deep-well pump blower inlet casing, comprise that zone line arranges the diversion disk of outlet, stand in the guide ring of diversion disk outer, and stand in some guide vanes on diversion disk, the end of described guide vane converges in outlet port, between adjacent two pieces of guide vanes and guide ring, surround import, it is characterized in that described guide vane is twisted blade.Twisted blade is double curvature blade, and blade surface and diversion disk out of plumb greatly reduce the hydraulic loss that fluid produces in the time of blower inlet casing inside transport, makes to use the deep-well pump efficiency of this blower inlet casing to improve 2% ~ 3% compared with conventional pump efficiency.
As further improving and supplementing technique scheme, the utility model adopts following technical measures: for making deep-well pump normally operation under the larger condition of sand content, described diversion disk bottom surface is provided with several anti-sand launders, and described anti-sand launder and guide vane are distributed in the both sides of diversion disk.When pump operation is in the situation that sand content is larger, silt particle is gathered in anti-sand launder more, and brings silt particle into next stage by vane rotary, greatly alleviates long-pending sand problem, greatly extends the working life of pump.Moreover, when conventional method design blower inlet casing, back shroud of impeller contacts and sticks together with diversion disk bottom surface when preventing from starting shooting, and at the easy adhesion of blower inlet casing region placement metal insert, this inserts and impeller cover are difficult for adhesion; And arrange after anti-sand launder, because the water being full of in anti-sand launder plays lubrication, therefore without placing inserts.More very, in the time of normal operation, there is gap between back shroud of impeller and diversion disk in traditional pump, is full of liquid, because this interstitial fluid that rotarily drives of impeller rotates centered by rotating shaft, finally with form of heat loss in this gap.And be provided with after anti-sand launder, liquid is not rule rotation, in the runner that a part of liquid inflow guide vane surrounds, most of fluid dynamic energy is converted to utilizable pressure energy by fluid passage, energy part is recovered, and lift of pump increases before, and efficiency improves 1% ~ 2%.
Described anti-sand launder number is identical with guide vane number, and its deflection direction is consistent with guide vane rotation direction.
Described guide vane quantity is 5 ~ 7.
The passage that described guide vane and diversion disk surround is fluid passage, and its area of passage is increased to outlet gradually by import, and discharge area and inlet-duct area are than between 1.05 ~ 1.3.
The beneficial effect the utlity model has: the twisted blade that guide vane is designed to double curvature, flow passage structure meets fluid flowing law, most of fluid dynamic energy is converted to utilizable pressure energy, energy part is recovered, lift of pump increases before, in stator, hydraulic loss greatly reduces, and has improved pump efficiency; The setting of anti-sand launder, not only improved the sand controlling result of pump, and diversion disk region is without metal insert, greatly reduces cost of material.

Fig. 2 is the backsight structural representation of Fig. 1.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: deep-well pump blower inlet casing, as shown in Figure 1, comprise that zone line arranges the outlet of outlet 31(blower inlet casing, fluid transport is outer to next stage Zhuan Neng mechanism or excavationg pump) diversion disk 3, stand in the guide ring 1 of diversion disk 3 outers, and stand in the some guide vanes 2 on diversion disk, the end of described guide vane 2 converges in outlet 31 places, between adjacent two pieces of guide vanes and guide ring, surround import 32, it is characterized in that described guide vane 2 is for twisted blade.As shown in Figure 2, diversion disk 3 bottom surfaces are provided with several anti-sand launders 4, and described anti-sand launder 4 and guide vane 2 are distributed in the both sides of diversion disk 3.The quantity of described guide vane 2 and anti-sand launder 4 is 6.The deflection direction of described anti-sand launder is consistent with guide vane rotation direction.
Described guide vane 2 is fluid passage with the passage that diversion disk 3 surrounds, and its area of passage is increased to outlet gradually by import, and discharge area and inlet-duct area compare between 1.05 ~ 1.3.The discharge area of fluid passage is 1.2 with inlet-duct area ratio.
The utility model is simple in structure, designs ingeniously, and sand controlling result is good, compared with traditional blower inlet casing, more can be useful in the environment operation that sand content is larger, particularly when new well well-flushing, greatly widens well pump Environmental Conditions.
