Abstract
The utility model belongs to a pump especially indicates a swirl air pump. According to the utility model provides a design has the impeller in the pump body, has the pump cover at the tip of the pump body, sets up the exit of air pump, characterized by on the pump body: the two ends of the main shaft of the motor respectively extend out of the motor, 1 air pump mainly composed of a pump body and an impeller is respectively and symmetrically arranged on the extending section of the main shaft, and the inlet of one air pump is connected with the outlet of the other air pump. After the air pump is utilized, the pressure of the air pump can be effectively improved, and meanwhile, the structure of the pump body is simplified, and the air pump is convenient to mount and use.
Description
Technical field
The utility model belongs to a kind of pump, refers in particular to a kind of vortex pump.
Background technique
In the prior art, vortex pump mostly is single-stage pump greatly, and this pump adds upper pump casing and pump cover and motor by an impeller usually and forms, and when needs improved the malleation of air pump or negative pressure, generally can pass through dual mode: a kind of was the diameter that adds the atmospheric pump impeller; Another kind is with the use that is together in series of two separate air pumps, and the outlet that is about to first air pump utilizes pipeline to be connected in the import of second air pump.But because the restriction of certain occasion mounting point, or cause the complicated of air pump blade wheel structure after strengthening impeller diameter, inadvisable under most occasions with strengthening impeller with the method that improves pressure; And with two independently air pump series connection use and bring inconvenience also can for user's installation and use.
Summary of the invention
The purpose of this utility model is to design a kind of twin-stage vortex pump, utilize this air pump after, can effectively improve air pump pressure, simplify the structure of the pump housing simultaneously, convenient install and use.
According to design proposal provided by the utility model, impeller is arranged in the pump housing, there is pump cover end at the pump housing, the import and export of air pump are set on the pump housing, it is characterized in that: motor is stretched out at the two ends of motor main shaft respectively, the pump housing is installed at two ends at motor respectively, and the impeller in the pump housing is installed on respectively on overhanging section of main shaft, and the import of one of them air pump is connected with the outlet of another air pump.
End cap is installed at two ends at motor field frame respectively, connects pump seat respectively in the outside of two end caps, and the pump housing is installed on the pump seat.The import and export of the pump housing all are positioned at the same side.On the main shaft in the cavity that pump seat and end cap surround blade is installed.Motor mounting is on base.
The utility model has the advantages that: owing to two vortex pumps are installed in the two ends of motor respectively, constitute the twin-stage vortex pump that is connected in series, compare with original mode, designs simplification and compactness, manufacturing, use and installation are all more convenient, have especially dwindled whole the space that two-stage pump is shared.This in addition structure can also improve the force-bearing situation of main shaft effectively.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is end cover structure figure.
Fig. 3 is the pump seat structural drawing.
Embodiment
As shown in the figure: impeller 5 is arranged in the pump housing 4, in the end of the pump housing 4 pump cover 6 is arranged, the import and export 10 of air pump are set on the pump housing 4, motor 1 is stretched out at the two ends of motor main shaft 7 respectively, the pump housing 4 is installed at two ends at motor 1 respectively, impellers 5 in the pump housing 4 are installed on respectively on overhanging section of main shaft 7, and the import of one of them air pump is connected with the outlet of another air pump.During design, the main shaft 7 and the end cap thereof of motor 1 improved, so that two air pumps are installed at the two ends of main shaft 7.During work, motor 1 drives impeller 6 rotations of two air pumps, and air enters from the import of an air pump, after this air pump pressurization, delivers to another air pump again and continues pressurization, and outlet pressure is greatly improved.
The section of pump seat 3 is bowl-shape, is provided with at the middle part of pump seat 3 and is convenient to the through hole 14 that main shaft passes, and the mounting hole of being convenient to install 13 is set on pump seat 3.
