Abstract
The utility model discloses an integral impeller, including front shroud, back shroud, medium runner and several work blade, the outer wall middle part of back shroud has set firmly hookup screw, its characterized in that several work blade equipartition on the circumference, the radial outer end in front side of every work blade all connects firmly with the front shroud, and radial the inner in front side of every work blade is located the place ahead of medium runner import, and the rear end of every work blade all connects firmly with the back shroud, the utility model discloses can improve the vacuum of medium runner import department to improve the suction force of impeller, promote the lift of submerged pump.
Description
Technical field
This utility model relates to a kind of monoblock type impeller.
Background technology
The monoblock type impeller of existing various submerged pump, including front shroud, back shroud, medium runner and several working-blade, the center of front shroud is located in the import of medium runner, the sidepiece between front shroud and back shroud is located in the outlet of medium runner, several working-blades are located in medium runner and integrally connect firmly with forward and backward cover plate, are installed with connection screw in the middle part of the outer wall of back shroud；These structure current are that streamlined flow enters in impeller, and the vacuum of the import department of medium runner is relatively low, causes that the suction force of impeller is on the low side, affects the lift of submerged pump.
Utility model content
The purpose of this utility model is for prior art above shortcomings, it is provided that a kind of monoblock type impeller, and it can improve the vacuum of medium runner import department, thus improving the suction force of impeller, promotes the lift of submerged pump.
For reaching above-mentioned purpose, a kind of monoblock type impeller of the present utility model, including front shroud, back shroud, medium runner and several working-blade, connection screw it is installed with in the middle part of the outer wall of back shroud, it is characterized in that described several working-blade is circumferentially uniform, the front side radial outer end of each working-blade all connects firmly with front shroud, and the front side radial inner end of each working-blade is positioned at the front of medium runner import, and the rear end of each working-blade all connects firmly with back shroud；
During work, impeller rotates, owing to the front side radial inner end of each working-blade is positioned at the front of medium runner import, current are driven to increase a rotational flow in medium runner import front, the vacuum of impeller eye can being promoted, increasing suction force, thus promoting the lift of submerged pump；
As further improvement of the utility model, it is fixedly connected with several uniform rear back blade at back shroud outer wall, is fixedly connected with several uniform front back blade at front shroud outer wall；The setting of forward and backward back blade can balance the axial force of impeller, reduces backflow simultaneously；
In sum, this utility model can improve the vacuum of medium runner import department, thus improving the suction force of impeller, promoting the lift of submerged pump, and reducing backflow.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1 and Figure 2, this monoblock type impeller, including front shroud 1, back shroud 2, medium runner 3 and three working-blades 4, connection screw 5 it is installed with in the middle part of the outer wall of back shroud 2, described three working-blades 4 are circumferentially uniform, the front side radial outer end 4a of each working-blade 4 all integrally connects firmly with front shroud 1, and the front side radial inner end 4b of each working-blade 4 is positioned at the front of medium runner 3 import, and the rear end of each working-blade 4 all integrally connects firmly with back shroud 2；It is fixedly connected with five uniform rear back blades 6 at back shroud 2 outer wall, is fixedly connected with five uniform front back blades 7 at front shroud 1 outer wall；
During work, impeller rotates, owing to the front side radial inner end 4b of each working-blade 4 is positioned at the front of medium runner 3 import, current are driven to increase a rotational flow in medium runner 3 import front, the vacuum of impeller eye can being promoted, increasing suction force, thus promoting the lift of submerged pump；Front back blade 7, rear back blade 5 setting can balance the axial force of impeller, reduce backflow simultaneously.
