Description
Technical field
The present invention relates to a kind of shell of guide pump.
Background technology
A kind of Inner guide housing of existing bull connection, which typically interlocks the line of centres of multiple adpting flanges, at present is
A bit, although this design contributes to overall gravitational equilibrium, the pressure for unilateral pedestal is reduced, multidirectional current staggeredly will
The current of main flow pipe are broken up, and flow loss is larger, increase energy consumption, less efficient.
The content of the invention
It is an object of the invention to provide a kind of Inner guide housing, adpting flange and shell eccentric setting, it is to avoid flow loss.
The present invention is a kind of Inner guide housing for being proposed of its technical problem of solution, including shell, support housing pedestal,
Adpting flange, the second adpting flange, enclosure are installed and impeller are provided with wall provided with cavity is installed, and its front opening is described
The surrounding that is open outer rim sets some raised fixed locks；Pedestal is made up of two pieces of support frames, is arranged at outer casing underpart, the branch
The reinforcement of connected with outer casing is set in the middle part of support；Adpting flange is arranged at shell rear portion, and the second adpting flange is arranged at shell top
Portion, the line of itself and housing center has 30 °~60 ° of angle with plumb line, is adjusted according to blade dimensions, when current from
Water impact impeller side when outer casing inner wall is flowed at the second adpting flange, impeller is rotated, and improves efficiency.
Adpting flange sets annular mounting frame in surrounding, and some strips are set between adpting flange and the annular mounting frame
Reinforcement, wherein any one piece of strip reinforcement surface is provided with detent, is easily installed main flow pipe.Positioned at strip reinforcement it
Between annular mounting frame surface provided with positioning hole, be easy to the connection of main flow pipe, prevent poorly sealed, cause hydraulic pressure not enough.
Reinforcement is provided between flange and the second adpting flange and shell in succession, shell and the second adpting flange inwall are applied provided with anti-oxidant
Layer, prevents high-temperature oxidization equipment.
It is an advantage of the current invention that adpting flange and shell eccentric setting, guide the current of cover top portion into edge, reduce
Flow loss；Strip reinforcement is set between adpting flange and the annular mounting frame, device damage is prevented；Mounting groove and positioning
Hole is easily installed.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Diagram and specific embodiment are closed, the present invention is expanded on further.
As shown in figure 1, a kind of Inner guide housing, including pedestal 2, the adpting flange 3, second of shell 1, support housing are connected
Flange 4, the inside of shell 1 sets some raised fixing locks provided with cavity, its front opening, the opening surrounding outer rim is installed
Button；Pedestal 2 is made up of two pieces of support frames, is arranged at the reinforcement that connected with outer casing 1 is set in the middle part of the bottom of shell 1, support frame as described above
Adpting flange 3 is arranged at the rear portion of shell 1, and the second adpting flange 4 is arranged at the top of shell 1, its line with the center of shell 1 with again
Vertical line has 30 °~60 ° of angle.Adpting flange 3 sets annular mounting frame, adpting flange and the annular mounting frame in surrounding
Between some strip reinforcements are set, wherein any one piece of strip reinforcement surface is provided with detent.Positioned at strip reinforcement
Between annular mounting frame surface provided with positioning hole.It is provided with and adds between the adpting flange 4 of flange 3 and second and shell 1 in succession
Strengthening tendons, the inwall of 1 and second adpting flange of shell 4 is provided with antioxidant coating.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent is defined.
