Abstract
The utility model discloses a desulphurization pump impeller with back vanes. The desulphurization pump impeller with the back vanes aims at resolving the problems that when an existing desulphurization pump adopts a balance hole structure to guarantee the balance of an impeller, the performances of the desulphurization pump are affected, the service life of the impeller is shortened; meanwhile, vibration and noise are produced, and the physical and psychological health of workers is affected. The desulphurization pump impeller with the back vanes comprises an impeller inlet, a front cover plate and a rear cover plate, wherein the rear cover plate is provided with an installation shaft hole, a front vane is arranged between the front cover plate and the rear cover plate, and a plurality of back vanes are arranged on the surface, far away from the front cover plate, of the rear cover plate. The desulphurization pump impeller with the back vanes effectively avoids the loss of flow caused by balance holes, improves the efficiency of the desulphurization pump, guarantees the flowing state of original medium, reduces abrasion of the impeller, and prolongs the service life of equipment. Besides, the desulphurization pump impeller with the back vanes effectively is delicate in concept, simple in structure, convenient to use, and capable of effectively improving the efficiency of the desulphurization pump and prolonging the service life of the impeller.
Description
Technical field
The utility model relates to mechanical field, and especially the desulfur pump field is specially a kind of desulfurized pump impeller with back blade.
Background technique
At present, in desulfur pump, in order to guarantee the balance of impeller, usually can balanced hole structure be set at impeller.Yet the backflow leakage of equalizing orifice can cause flow loss, affects the desulfurization pump performance, and therefore, the efficient of the impeller in balance hole is lower.Simultaneously, equalizing orifice can change original media flow state, causes the waterpower bump, not only can produce vibration and noise, affects workman's physical and mental health, and bump meeting accelerating medium in the working life of shortening impeller, increases cost of production to the wearing and tearing of impeller.
The model utility content
Goal of the invention of the present utility model is: at present in desulfur pump, adopt balanced hole structure to guarantee the balance of impeller, can affect the desulfurization pump performance, shorten the working life of impeller, simultaneously, also can produce vibration and noise, affect workman's able-bodied problem, a kind of desulfurized pump impeller with back blade is provided.The utility model arranges back blade at impeller, and back blade rotates with impeller, produces back pressure, thereby plays the effect of balance impeller, and it can also effectively alleviate impeller pressure, reduces the load of seal ring, plays the effect of auxiliary seal.The flow loss that the utility model has effectively avoided equalizing orifice to produce has improved the efficient of desulfur pump, has guaranteed simultaneously original media flow state, has reduced the wearing and tearing of impeller, has prolonged the working life of equipment.The utility model is skillfully constructed, and is simple in structure, easy to use, and efficient that can the Effective Raise desulfur pump prolongs working life of impeller.
In order to address the above problem, the utility model adopts following technological scheme:
A kind of desulfurized pump impeller with back blade, comprise impeller inlet, front shroud, back shroud, be provided with installation axle hole on the described back shroud, be provided with front vane between described front shroud and the back shroud, described back shroud is evenly equipped with some back blades on the surface away from front shroud.
Described front vane, back blade are respectively arc.
The quantity of described back blade is even number.
The quantity of described front vane is four, and the quantity of back blade is eight.
Be provided with connecting thread on the inwall of described installation axle hole.
Also be provided with the sunk screw hole on the described back shroud, described sunk screw hole links to each other with installation axle hole.
Adopt integral casting forming.
The utility model adopts integral casting forming technique, and its production technology is simple, and is easily manufactured, with short production cycle, installation, easy to maintenance, long service life.The utility model comprises impeller inlet, front shroud, back shroud, and the two sides of back shroud is respectively arranged with front vane, back blade.Front vane, back blade are respectively arc.Wherein, the quantity of back blade is take even number as good, and as preferably, the quantity of front vane is four, and the quantity of back blade is eight.Be provided with in the heart installation axle hole in the back shroud, be provided with connecting thread on the inwall of installation axle hole, also be provided with the sunk screw hole on the back shroud, the sunk screw hole links to each other with installation axle hole.
When the utility model in when work, back blade rotates with back shroud, produces back pressure, thereby reaches the purpose that makes impeller balance, effectively alleviates simultaneously impeller pressure, plays the effect of auxiliary seal.Inventor of the present utility model has adopted respectively back blade is the modes such as radial arrangement along the center of back shroud in practice, the final discovery, and when the back blade on back shroud is arc, its best results.The utility model is provided with installation axle hole at back shroud, is provided with connecting thread on the inwall of installation axle hole, and it can make between impeller and the pump shaft and be threaded connection; The sunk screw hole that arranges on the back shroud can make pump shaft be connected and fixed with sunk screw, thereby effectively simplifies the installation of impeller and fixing, prevents the phenomenons such as impeller becomes flexible in the course of the work, comes off.Owing to having adopted back blade, the efficient of impeller is greatly improved, and therefore, the blade quantity of the existing impeller of the front vane quantity in the utility model is few, can also alleviate vane thickness simultaneously, has effectively reduced the impeller deadweight, has reduced cost of production.Under the same conditions, compare with existing desulfur pump, the utility model is subjected to the impact of medium less, and effectively prolonged working life.The utility model can be selected wear-resisting, corrosion resistant material, thereby increases the wear-resisting and corrosion resistance of impeller, the working life of greatly improving impeller.
The utility model is skillfully constructed, and is simple in structure, is easy to install, safeguard, efficient is high, long service life.
