The model utility content
The utility model will solve the problem that above-mentioned prior art exists, and a kind of double shrouded wheel is provided, and is rational in infrastructure, easy to use, and water inlet and water outlet are effective, and the hydraulic efficiency height can increase the working efficiency of centrifugal pump, has satisfied people's demand.
The utility model solves the technological scheme that its technical problem adopts: this double shrouded wheel, comprise front shroud, back shroud, be located at the blade between front shroud and the back shroud, the center of front shroud convexes with the water intake of ring-type, water intake is axial suction setting, front shroud is provided with between the bottom surface of the one side of water intake and water intake and is the acute angle setting, blade and front shroud, arrange for sealing between the back shroud, blade is dull and stereotyped curve backward inclined blade, the quantity of blade is eight, cavity between front shroud and the back shroud is separated into eight water outlets by eight blades, water outlet is radially output setting, and back shroud is provided with external bushing.After arranging like this, rational in infrastructure, easy to use, water intake is axial suction setting, current enter by eight water outlets that radially arrange from water intake and flow out, can improve hydraulic efficiency, thereby can improve the working efficiency of centrifugal pump, front shroud is provided with between the bottom surface of the one side of water intake and water intake and is the acute angle setting, has increased the cavity volume between blade and the front shroud like this, can reduce the waterpower load that blade is subjected to, can increase the working life of double shrouded wheel, can improve the hydraulic efficiency of double shrouded wheel, can also be added to the water yield, improve the water outlet effect.
The acute angle angular range that front shroud is provided with between the bottom surface of the one side of water intake and water intake is 20 °～50 °.After arranging like this, this acute angle angular range is preferable scope, can either increase hydraulic efficiency, can reduce the waterpower load that blade is subjected to again, increases the working life of double shrouded wheel.
The acute angle angle that front shroud is provided with between the bottom surface of the one side of water intake and water intake is 30 °.After arranging like this, the acute angle angle is optimum value.
Blade is stainless steel blade.After arranging like this, can satisfy the working strength requirement of blade.
Front shroud is the stainless steel front shroud.After arranging like this, can satisfy the working strength requirement of front shroud.
Back shroud is the stainless steel back shroud.After arranging like this, can satisfy the working strength requirement of back shroud.
The effect that the utility model is useful is: double shrouded wheel of the present utility model, rational in infrastructure, easy to use, the bulk strength height, water intake is axially to suck to arrange, water outlet can improve the effect of water inlet and water outlet for radially output setting, improves hydraulic efficiency, increased the cavity volume between blade and the front shroud, can reduce the waterpower load of blade, can increase the working life of blade, using effect is good.
