Description
Technical field
The invention belongs to water pump appliance technology more particularly to a kind of intracorporal guide vane mechanisms of blower inlet casing.
Background technique
Currently, the consideration that the centrifugal pump guide vane of big flow is high due to required intensity, generally cast structure, at present above on
Guide vane structure with floating choma, diversion shell is precision cast structure, its advantage is that intensity is high.Disadvantage is also apparent from：Casting
It is long to make the period, at high cost, and pollution is high, is easy to appear casting flaw.The intensity of diversion shell current simultaneously is inadequate, often occurs
Problem.
Summary of the invention
It is an object of the invention to solve the problems, such as techniques discussed above, providing one kind can be with intensity height, and cost is opposite to drop
Low, the manufacturing cycle is short, almost pollution-free to environment in high-efficient, manufacturing process, the intracorporal guide vane of very environmentally friendly blower inlet casing
Mechanism, its technical solution is as follows：
The intracorporal guide vane mechanism of blower inlet casing, which is characterized in that including guide vane and extended blade, the extended blade setting
In the both sides of guide vane, the extended blade is S-shaped, is continuous indent at the obverse and reverse of the extended blade
Saw-tooth grooves, the positive saw-tooth grooves of extended blade are by punch welding on guide vane.Extended blade is S-shaped main
It is, so that welding is more stable, to enhance whole intensity for increasing the area welded.Saw-tooth grooves can increase
The contact surface of welding enhances its stability so that the welding of extended blade and inner support, lower cover is more secured.Guide vane
On piece has extended blade, and extended blade is bonded with the inner wall of the outer wall of inner support and lower cover respectively, and welding is stronger, increases and leads
Flow the intensity of shell.
Preferred embodiment is to offer V-arrangement ditch in the saw-tooth grooves.When V-arrangement ditch can make welding, melt
Metal liquid can be flowed into V-arrangement ditch, to enhance stability.
Preferred embodiment is that the guide vane and extended blade are all that stainless steel plate is formed by punch welding.Entirely lead
Blade mechanism is all punch welding structure, and for shape close to Theoretical Design, hydraulic loss is small, so high-efficient.
The beneficial effects of the invention are as follows：Can be with intensity height, cost relative reduction, the manufacturing cycle is short, high-efficient, manufacturing process
In it is almost pollution-free to environment, it is very environmentally friendly.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
Specific embodiment
Below with reference to Fig. 1 specific illustrative embodiment：
The intracorporal guide vane mechanism of blower inlet casing, including guide vane 1 and extended blade 2, the extended blade are set to guide vane
Both sides, the extended blade is S-shaped, at the obverse and reverse of the extended blade for continuous indent zigzag it is recessed
Slot 3, the positive saw-tooth grooves of extended blade are by punch welding on guide vane.Extended blade is S-shaped to be mainly used for
Increase the area of welding, so that welding is more stable, enhances whole intensity.Saw-tooth grooves can increase welding
Contact surface enhances its stability so that the welding of extended blade and inner support, lower cover is more secured.Have on guide vane
Extended blade, extended blade are bonded with the inner wall of the outer wall of inner support and lower cover respectively, and welding is stronger, increase diversion shell
Intensity.
Preferred embodiment is that V-arrangement ditch 4 is offered in the saw-tooth grooves.When V-arrangement ditch can make welding, melt
The metal liquid of change can be flowed into V-arrangement ditch, to enhance stability.
Preferred embodiment is that the guide vane and extended blade are all that stainless steel plate is formed by punch welding.Entirely lead
Blade mechanism is all punch welding structure, and for shape close to Theoretical Design, hydraulic loss is small, so high-efficient.
When specifically used, guide vane and extended blade are that setting is intracorporal in blower inlet casing.Diversion shell is by upper outer
Shell, upper cover, lower casing, lower cover, guide vane punch welding are formed, and extended blade is provided on the guide vane, and described prolongs
Blade is stretched to be bonded with the inner wall of the outer wall of inner support and lower cover respectively；Guide vane inner sleeve is provided in the diversion shell, circlip floats
It opens one's mouth ring, choma lid.
