Description
Technical field
The utility model relates to a kind of vertical type centrifugal pump.
Background technique
Centrifugal pump 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 vertical type centrifugal pump, has the advantages that efficiency is high, noise is low.
For solving the problems of the technologies described above, the utility model provides a kind of vertical type centrifugal pump, comprises a upright pump housing, is arranged on the intake pipe bottom the pump housing, be arranged on the outlet pipe of pump housing upper end portion, and be fixed on the motor at pump housing top by motor rack.In addition, centrifugal pump also comprises the impeller shaft being arranged on vibration damper bottom the pump housing, arranging through the longitudinal direction at pump housing top; The top of impeller shaft is connected with the motor shaft of motor by coupling, and the bottom of impeller shaft is fixed on bottom the pump housing by guide bearing; Impeller shaft is provided with impeller and stator successively, and wherein stator is located at the top of impeller; The joint, top of impeller shaft and the pump housing is provided with bearing and seal ring, and seal ring is arranged on the top of bearing.
Further, motor is water-cooled machine, and the cooling water tank of water-cooled machine is connected with outlet pipe with the intake pipe of centrifugal pump respectively by aqueduct.
Further, the quantity of stator is two.
The beneficial effects of the utility model are:
1, the utility model adopts vertical type channel design, and installation and maintenance are very convenient, and its current are smooth, and working efficiency is high.
2, water intake of the present utility model is arranged on the bottom of whole centrifugal pump, can aspirate excess surface water to greatest extent; And above impeller, be provided with two stators, the water-outlet quantity of whole pump can be kept to keep evenly.
