The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of draining pump with larger working pressure.
The purpose of this utility model realizes by following technical proposal: a kind of draining pump, comprise motor and the pump housing, the rotating shaft that the described pump housing comprises housing and is axially connected in described housing, the upper end of described rotating shaft stretches out in described housing and is connected mutually with the main shaft of described motor, it is characterized in that, described housing comprises feed-water end and waterexit end, described rotating shaft is fixed with main impeller and auxiliary impeller, described auxiliary lobe wheel is positioned at described feed-water end place, the sidepiece of described main impeller and the sidepiece of described auxiliary impeller is all curved and both are tangent setting.
Operationally, the rotation of driven by motor rotating shaft, and drive the rotation of main impeller and auxiliary impeller, water is sucked from feed-water end and is discharged by waterexit end, owing to rotating shaft being fixed with main impeller and auxiliary impeller, therefore, it is possible to better carry out the effect of drainage to current, this draining pump is made to have larger working pressure.
In above-mentioned a kind of draining pump, the radius of the sidepiece of described auxiliary impeller: the radius of the sidepiece of described main impeller is 1:1.2-1:1.5.
In above-mentioned a kind of draining pump, the upper end of described housing is provided with pump cover, and the main shaft of described motor is through described pump cover and be provided with seal ring described main shaft and described pump cover.Be provided with seal ring between main shaft and pump cover, there is good sealing effect, avoid the leakage of water pump.
In above-mentioned a kind of draining pump, described feed-water end and described rotating shaft are arranged in coaxial, and described waterexit end is positioned at the sidepiece of described housing and described feed-water end and described waterexit end are vertical setting.Feed-water end and waterexit end are vertical setting, and make this draining pump structure comparatively reasonable.
In above-mentioned a kind of draining pump, described main impeller and described auxiliary impeller all adopt aluminum alloy material to make.Main impeller and auxiliary impeller all adopt aluminum alloy material to make, and have lighter in weight and the less advantage of energy consumption.
Compared with prior art, this kind of draining pump has the following advantages:
1, the rotation of driven by motor rotating shaft, and drive the rotation of main impeller and auxiliary impeller, water is sucked from feed-water end and is discharged by waterexit end, owing to rotating shaft being fixed with main impeller and auxiliary impeller, therefore, it is possible to better carry out the effect of drainage to current, this draining pump is made to have larger working pressure;
2, be provided with seal ring between main shaft and pump cover, there is good sealing effect, avoid the leakage of water pump;
3, main impeller and auxiliary impeller all adopt aluminum alloy material to make, and have lighter in weight and the less advantage of energy consumption.
