Abstract
The utility model relates to a horizontal straight receipts or other documents in duplicate level vortex pump, including base, the pump body, connecting seat, motor, impeller and pivot, it forms volute chamber and sealed cavity to be separated in the pump body, the pump body, connecting seat, motor in proper order fixed set up in on the base just pump body volute chamber is located one side of the sealed cavity of the pump body, the rotatable setting of pivot is in the pump body, the impeller with the one end of pivot is connected and be in in the volute chamber, the other end of pivot passes sealed cavity with the motor is connected, the volute chamber transversely is provided with the sunction inlet and vertically be provided with the delivery port, the front side of impeller edge with the relative inner wall of volute chamber is apart from the 3 -5 millimeter. The utility model discloses compare with the centrifugal pump, produce same lift diameter of impeller and want little by 20%, can obviously reduce the volume of pump, alleviate the weight of pump, because the utility model discloses no sealing ring, thus there is not the problem that the running clearance increase of wearing and tearing rear pump body and impeller leads to pump performance to descend.
Description
Technical field
The utility model relates to torque flow pump field, is especially a kind of horizontal direct connection single-stage torque flow pump.
Background technique
Existing horizontal direct connection single-stage pump product, mainly adopts centrifugal pump structure, the running clearance in high and low pressure chamber in pump, namely the matching gap between the pump housing and impeller, realize sealing with seal ring, there is following shortcoming in it: produces same lift, centrifugal pump impeller diameter is large, causes pump volume to increase; After long-play, pump seal ring portion position meeting Fast Wearing, causes pump performance to decline; Major part centrifugal pump, increase with flow, lift declines continuously and healthily, can not meet the requirement of fire water pump standard.
Model utility content
The utility model object is to solve the problem, and provides a kind of horizontal direct connection single-stage torque flow pump, is specifically realized by following technological scheme:
A kind of horizontal direct connection single-stage torque flow pump, comprise base, connecting base that the pump housing, top are provided with sealed chamber, motor, impeller and rotating shaft, the described pump housing, connecting base, motor are fixedly installed on described base successively has volute chamber in the described pump housing, thus described pump housing volute chamber is positioned at the side of pump housing sealed chamber, described rotating shaft is rotatably arranged in the pump housing, described impeller is connected with one end of described rotating shaft and is in described volute chamber, and the other end of rotating shaft is connected with described motor through described sealed chamber; Described volute chamber is horizontally arranged with suction port and is vertically arranged with water outlet, the forward edge of described impeller and the opposed inner walls distance 3-5 millimeter of described volute chamber.
Described horizontal direct connection single-stage torque flow pump, it designs further and is, described impeller is provided with back blades.
Described horizontal direct connection single-stage torque flow pump, it designs further and is, described impeller is eddy flow pump type impeller, and described volute chamber is eddy flow pump type volute chamber.
The beneficial effects of the utility model are: the utility model, compared with centrifugal pump, produces same lift impeller diameter and wants little by 20%, obviously can reduce the volume of pump, alleviate the weight of pump; Because the utility model is without seal ring, the running clearance not depositing the pump housing and impeller upon wear increases thus the problem causing pump performance to decline; The utility model lift is in the effective using scope of flow, almost constant, can meet to specify in China GB6245-2006 fire water pump, and pump is when rated flow 150%, lift is not less than the regulation of rated lift 65%, is specially adapted to fire water pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is further described:
As shown in the figure, this horizontal direct connection single-stage torque flow pump comprises base 1, the pump housing 2, connecting base 6 with sealed chamber 12, motor 3, impeller 4 and rotating shaft 5, volute chamber 11 is provided with in the pump housing, the pump housing 2, connecting base 6, motor 3 are fixedly installed on base successively, pump housing volute chamber is made to be positioned at the side of sealed chamber, rotating shaft 5 is rotatably arranged in the pump housing, and impeller 4 is connected with one end of rotating shaft and is in volute chamber, and the other end of rotating shaft is connected with motor through sealed chamber.
Volute chamber is horizontally arranged with suction port and is vertically arranged with water outlet, the forward edge of impeller and the opposed inner walls distance 3-5 millimeter of volute chamber.Impeller 4 is eddy flow pump type impeller, and volute chamber 11 is eddy flow pump type volute chamber.Impeller 4 is provided with back blades, plays the effect of balancing axial thrust.
The beneficial effects of the utility model are: the utility model, compared with centrifugal pump, produces same lift impeller diameter and wants little by 20%, obviously can reduce the volume of pump, alleviate the weight of pump; Because the utility model is without seal ring, the running clearance not depositing the pump housing and impeller upon wear increases thus the problem causing pump performance to decline; The utility model lift is in the effective using scope of flow, almost constant, can meet to specify in China GB6245-2006 fire water pump, and pump is when rated flow 150%, lift is not less than the regulation of rated lift 65%, is specially adapted to fire water pump.
