Abstract
The invention relates to a vertical centrifugal pump. The vertical centrifugal pump comprises a pump body, an impeller, a pump cover, a shaft, a motor frame and a motor, wherein the pump cover, the motor frame and the motor are sequentially fixed above the pump body; the impeller is fixed into a pump chamber formed between the pump cover and the pump body; the impeller is fixed to the lower end of the shaft; the shaft passes through the pump cover and then is connected with an output shaft of the motor; a mechanical seal is formed between the pump cover and the shaft; and an inlet of the pump body is formed at the bottom of the pump body, and while an outlet of the pump body is formed on the side surface of the pump body. According to the vertical centrifugal pump, the outlet of the pump body is higher than the inlet, so that little air entering the inlet also can be exhausted from the outlet of the centrifugal pump together with a medium, and as a result, high reliability and safety are ensured during use of the centrifugal pump, and the performance can be ensured well.
Description
Technical field
The present invention relates to centrifugal pump, specifically a kind of vertical centrifugal pump.
Background technique
Vertical centrifugal pump is the centrifugal pump that a kind of pump shaft is positioned at the vertical position.Existing vertical centrifugal pump, its structure as shown in Figure 1, comprise the pump housing 1, impeller 2, pump cover 3, axle 4, motor rack 5 and motor 6, pump cover 3 is fixed on the top of the pump housing 1, form the pump chamber that impeller 2 is installed between pump cover 3 and the pump housing 1, motor rack 5 is fixed on the top of pump cover 3, and motor 6 is fixed on the top of motor rack 5, the axle 6 of impeller 2 links to each other with the output shaft of motor 6 after passing pump cover 3, is provided with the machine sealing chamber of fitting machine envelope 7 between pump cover 3 and the axle 4.
This vertical centrifugal pump, the import 8 of its pump housing 1 is located on the same line with outlet 9, and in use, if import 8 has Air infitration, air can be difficult to get rid of always in pump, causes the impact of vertical performance of centrifugal pump.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of vertical centrifugal pump of reliable performance is provided.
According to technological scheme of the present invention: a kind of vertical centrifugal pump, comprise the pump housing, impeller, pump cover, axle, motor rack and motor, the top of the described pump housing is fixed with described pump cover, described motor rack and described motor successively, described impeller is fixed in the pump chamber that forms between described pump cover and the described pump housing, described impeller is fixed on the lower end of described axle, described axle links to each other with the output shaft of described motor after passing described pump cover, and organic envelope is installed between described pump cover and the described axle; The import of the described pump housing is positioned at the bottom of the described pump housing, and its outlet is positioned at the side of the described pump housing.
The below of the described pump housing is fixed with pump seat, is fixed with the right-angle elbow pipe that is connected with the import of the described pump housing in the described pump seat.
Technique effect of the present invention is: the outlet of middle pump body of the present invention is higher than import, even import has a small amount of air to enter, also can discharge from centrifugal delivery side of pump with medium, so the centrifugal pump use is more reliable and secure, and performance is also more secure.
Description of drawings
Fig. 1 is the structural representation of existing vertical centrifugal pump.
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1, Fig. 2, comprise the pump housing 1, impeller 2, pump cover 3, axle 4, motor rack 5, motor 6, machine envelope 7, import 8, outlet 9, right-angle elbow pipe 10, pump seat 11 etc.
As shown in Figure 2, the present invention is a kind of vertical centrifugal pump, comprises the pump housing 1, impeller 2, pump cover 3, axle 4, motor rack 5 and motor 6.
The top of the pump housing 1 is fixed with pump cover 3, motor rack 5 and motor 6 successively, impeller 2 is fixed in the pump chamber that forms between pump cover 3 and the pump housing 1, impeller 2 is fixed on the lower end of axle 6, and axle 6 links to each other with the output shaft of motor 6 after passing pump cover 3, and organic envelope 7 is installed between pump cover 3 and the axle 4.
The import 8 of the pump housing 1 is positioned at the bottom of the pump housing 1, and its outlet 9 is positioned at the side of the pump housing 1.Because outlet 9 is higher than import 8, be exactly import 8 has a small amount of air to enter, also can discharge from centrifugal delivery side of pump 9 with medium, so the centrifugal pump use to be more reliable and secure, performance is also more secure.
Below the pump housing 1, also be fixed with pump seat 11, in pump seat 11, be fixed with the right-angle elbow pipe 10 that is connected with the import 8 of the pump housing 1.Arrange right-angle elbow pipe 10, be convenient to the centrifugal pump water inlet.
Claims (2)
