Description
Technical field
The utility model belongs to fluid mechanics design field, is related to a kind of spatial guide blade.
Background technique
Guide vane is turn energy device of centrifugal pump, its effect is impeller to be thrown away the liquid come to collect, and makes liquid
Flow velocity reduces, and after partial velocity energy head is changed into pressure energy head, then is uniformly introduced next stage or is discharged by diffuser.
The effect of guide vane is identical as spiral case, is chiefly used in multistage segmental type pump.In centrifugal multistage pump multiple centrifugal pump, guide vane is fitted into in partition
Duan Zhong.Guide vane can be divided into radial guide vane and flow channel type guide blade by its structure type.The positive guide vane of flow channel type guide blade and reversed
Guide vane is cast together, and there is a continuous flow path in centre, flows liquid in continuous runner, is not easy to be formed dead angle and suddenly
Diffusion, velocity variations are relatively uniform, and hydraulic performance is preferable, but structure is complicated, and anufacturability is poor.Usual spatial guide blade is in import
Section can form whirlpool in inducer, be that guide vane hydraulic efficiency loses most places due to not having guiding device.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of spatial guide blade.
In order to achieve the above objectives, the utility model is achieved using following technical scheme:
A kind of spatial guide blade, including guide face partition, guide vane blade, shell, inner casing, mounting flange and wheel hub；Shell and
Inner casing is connected by guide vane blade, guide face partition be arranged between shell and inner casing on the surface of revolution of streamline and with guide vane blade
Connection, the input end of guide face partition extend forwardly into vane inlet and impeller outlet intersection, and mounting flange is arranged in shell
On, wheel hub is arranged in inner housing inner.
The utility model further improvement is that
The axial length of guide face partition is the 1/4 to 1/2 of guide vane blade axial length.
Guide face partition at least one.
The normal direction import laying angle of guide face partition is identical as the normal direction of impeller outlet end front shroud outlet laying angle.
Guide face partition, guide vane blade, shell, inner casing, mounting flange and wheel hub integrally casting shaping.
The material of guide face partition is stainless steel.
Compared with prior art, the utility model has the following beneficial effects:
Guide face partition is arranged in the utility model in gate vane channel, by the collective effect of guide vane and guide face partition,
It the case where improving guide vane internal flow state, reducing turbulent flow and Secondary Flow, effectively reduces the hydraulic loss of water inlet flow channel while changing
It has been apt to the larger problem of vane inlet end vortex, has improved the efficiency of pump；And the utility model has the advantages of simple structure, is easily installed.
Further, the normal direction of normal direction import laying angle and impeller outlet end front shroud that guide face partition is arranged, which exports, pacifies
It puts that angle is identical, preferably reduces the hydraulic loss of water inlet flow channel.
