Description
Technical field
The utility model relates to a kind of centrifugal pump.
Background technique
Centrifugal water pump is called for short " centrifugal pump ", and it is a kind of water lifting machinery utilizing the centrifugal motion of water.Be made up of pump case, impeller, pump shaft, pump bracket etc.Centrifugal water pump prestart first should fill water in pump, and the impeller rotated after starting drives the water High Rotation Speed in pump, and water makes centrifugal motion, outwards throws away and is pressed into outlet pipe.After water is thrown out of, the pressure near impeller reduces, near rotating shaft, just form a low pressure area.Here pressure is more much lower than barometric pressure, and the water of outside just under atmospheric pressure, is washed bottom valve open and entered in pump from intake pipe.The water rushed in is thrown out of again in impeller High Rotation Speed, and is pressed into outlet pipe.Impeller is continuous High Rotation Speed under power engine drives, and water is just pumped to eminence from lower continuously.
Model utility content
The purpose of this utility model is to provide a kind of centrifugal pump, its good sealing effect, and it can avoid the phenomenon that inner blocking occurs.
For solving the problems of the technologies described above, the utility model provides a kind of centrifugal pump, comprises pump case, main impeller, intake pipe, outlet pipe, filter and is arranged on the motor at pump case top;
The water intake of intake pipe is provided with flat thin magnet, and intake pipe is communicated with the water storage box be arranged on bottom pump case; Water storage box and centrifugal chamber connection position are provided with filter, and water outlet is connected with centrifugal chamber;
The top of centrifugal chamber is provided with upper end cap, and impeller shaft extends in centrifugal chamber through end cap and is connected with main impeller; Impeller shaft is connected by coupling with the motor shaft of motor; The bottom of end cap is also provided with sub-propeller in impeller shaft joint.
The beneficial effects of the utility model are: the utility model is provided with flat thin magnet in water inlet, iron filings in water can be removed, to prevent iron filings from destroying centrifugal pump interior arrangement, water storage box and centrifugal chamber connection are provided with filter, the impurity such as the mud in water, sand can be removed, to prevent blocking.In addition the utility model is provided with sub-propeller in the bottom of upper end cap, can strengthen the sealing of pump.
