Abstract
The utility model relates to a flow guiding device, in particular to a fixed type flow guiding device arranged at an impeller water outlet. The fixed type flow guiding device comprises a guide vane body and is characterized in that the guide vane body comprises 8-12 guide vanes, a diffusing pipe and a fixed flange. The axial height of the guide vane is 17-23mm. Angle of a diffusing angle of the diffusing pipe is 0 degree-10 degrees. A rotating fixed type buckle is arranged at the lower end face of the fixed flange. The guide vanes are arranged on the inner wall of the diffusing pipe. The fixed flange is arranged at the bottom of the diffusing pipe. The fixed type flow guiding device is capable of reducing hydraulic loss, enabling the speed to be transformed into pressure energy at the same time when the water velocity is reduced, increasing axial strength generated by an impeller and functioning as a protective cover.

Technical field
The utility model relates to a kind of flow guide device, particularly a kind of fixed flow guide device that is installed on the impeller water outlet.
Background technique
Typical swimming pool Intelligent sewage sucking robot (hereinafter to be referred as dirt-dredging machine) generally should be designed with impeller intake, impeller and impeller water outlet device.
The impeller protective housing has generally been installed at the impeller water outlet device place of existing dirt-dredging machine, and the problem that existing impeller protective housing produces is to change the direction that rotatablely moves that the impeller water outlet is discharged current.Usually current are discharged the hydraulic loss that causes with the separation of flow, velocity attitude and size variation etc. under the vane rotary motion, cause easily slatterning part energy, have reduced the axial force that impeller produces.
Summary of the invention
The problem that the utility model solves is the actual operation requirements for dirt-dredging machine, and the above drawback of avoiding the impeller protective housing to exist has solved the problems such as axial force that hydraulic loss, energy dissipation, impeller produce can't change.
The utility model is solved by following technical proposals:
A kind of fixed flow guide device comprises diffuser, and its structural feature is that described diffuser comprises stator, diffusing tube and fixed flange.The axial height of described stator is 17～23mm, and blade quantity is 8～12, and this design can guarantee effectively that it is axisymmetric that current are discharged mobile behind the impeller water outlet, has stable relative movement in the impeller thereby make, and reduces hydraulic loss.The angle of flare angle of described diffusing tube is 0～10 °.Described fixed flange lower end surface is provided with the fixed buckle of rotation.Vane apparatus is in the diffusing tube inwall, and fixed flange is installed on the diffusing tube bottom.
As preferably, described diffuser is installed on the water outlet of dirt-dredging machine, and described water outlet inwall is provided with impeller, and the Exit-edge of impeller and the parallel distance of stator are 3～6mm.Consider that the water outlet inwall is provided with the situation of impeller, the Exit-edge of stator and impeller is arranged certain parallel distance, guaranteed that effectively stator can not touch mutually with the water outlet inner facility, avoid damaging.
As preferably, caliber coupled water outlet aperture in described diffusing tube bottom equates.
As preferably, described being buckled on the 360 ° of directions in fixed flange lower end is evenly arranged, and quantity is 2～4.Buckle has realized simply and easily that as connection set fixed flow guide device is connected with the impeller water outlet.
As preferably, described fixed flange upper-end surface is provided with the sense of rotation indicative mark that indication is installed, and is convenient to personnel according to the fixed flow guide device of prompting loading and unloading.
The beneficial effect of technical solutions of the utility model is:
The utility model can be collected the liquid of discharging from the impeller water outlet by the axisymmetric mode, has stable relative movement in the impeller thereby make, and reduces hydraulic loss.Reducing water velocity simultaneously, so that speed can convert pressure energy to, increase the axial force that impeller produces.Also played simultaneously the effect of impeller protective housing.
