Description
Technical field
The utility model relates to a kind of Under Water Pumps, particularly discloses a kind of multi-level submerged pump.
Background technique
All wing wheels of traditional multi-level submerged pump focus mostly on away from the pump of bearing bottom, and as accompanying drawing 1, all below liquid level, because rotatable parts---several wing wheels reduce greatly away from the stability of bearing pump, the machining accuracy to pump also requires to improve simultaneously basically.For improving stability, have to add the diameter of big drive shaft.When pump began to start, all wing wheels were worked simultaneously, and inrush current is quite big.How can therefore increase relevant power device and the supporting motor of pump, and when normal operation, present the unreasonable power consumption of " low load with strong power ".
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, and the multi-level submerged pump that a kind of stability is high, energy consumption is low is provided.
The utility model is achieved in that a kind of multi-level submerged pump, comprise liquid inlet pipe, pump housing group, wing wheel group, coupling, support column, axle, drain pipe, driving mechanism, motor, described wing wheel group is positioned at described pump housing group, described wing wheel group and described driving mechanism link, described driving mechanism links to each other with described motor, it is characterized in that: described pump housing group is made of upper pump casing group, lower pump body, and described wing wheel group is made of upper limb wheels, following wing wheel; The top of described liquid inlet pipe links to each other with the lower end of described lower pump body, is connected with support column between the lower end of the upper end of described lower pump body and described upper pump casing group, and the upper end of described upper pump casing group links to each other with described drain pipe; Described bottom wing wheel is positioned at described lower pump body, described axle is positioned at described support column, described wing wheel down links to each other by the lower end of coupling with described axle, the upper end of described axle links to each other with the lower end of described upper limb wheels, the upper end of described upper limb wheels links to each other with described driving mechanism, and described upper limb wheels are positioned at described upper pump casing group.
Described lower pump body is made up of the single pump housing, and described upper pump casing group is made up of 1 ~ 7 pump housings, and the wing wheel quantity of described wing wheel group is corresponding with the pump housing quantity of described pump housing group.
The utility model on the basis of existing technology, with former away from the driving section and all concentrate and be connected on subsurface wing wheel group, only change a wing wheel under liquid level, all the other all move to the above and close transmission part place of liquid level, make the main rotation of pump partly approach to reduce the pump shaft swing with driving mechanism, the stability when having improved the pump running greatly; Simultaneously, during pump startup, all in liquid, worked at one time by original all wing wheels, only becoming a wing wheel works in liquid, top impeller is not owing to immerse liquid, so be idle running, greatly reduce the inrush current of pump like this, the necessary electromotor power of pump is selected for use also because not considering that inrush current reduces; After treating that subsurface down wing wheel promotes the upper limb wheels of liquid to the liquid level, the upper limb wheels continue to work in liquid, to reach the hydraulic performance that needs.
The beneficial effects of the utility model are: owing to move on the center of gravity, shortened the distance between wing wheel group and the bearing, thereby improved whole stability, simultaneously because having only a wing wheel under liquid, have only a wing wheel in liquid, to work during startup, inrush current reduces greatly, and this is particularly evident at large-scale Under Water Pumps or high-lift multi-stage pump.
