Abstract
The utility model relates to a vertical centrifugal pump, which 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 fixedly arranged above the pump body in sequence; the impeller is fixedly arranged in a pump cavity formed between the pump cover and the pump body and is fixedly arranged at the lower end of the shaft; the shaft penetrates through the pump cover and then is connected with an output shaft of the motor; a mechanical seal is arranged between the pump cover and the shaft; an inlet of the pump body is positioned at the bottom of the pump body; and an outlet of the pump body is positioned in a side face of the pump body. The outlet of the pump body is higher than the inlet, and even if a small amount of air enters from the inlet, the air can be discharged from the outlet of the centrifugal pump along with a medium, so that the centrifugal pump is more reliable and safer to use and the performance is also guaranteed.
Description
Technical field
The utility model 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 frame 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 frame 5 is fixed on the top of pump cover 3, and motor 6 is fixed on the top of motor frame 5, the axle 6 of impeller 2 passes pump cover 3 backs and links to each other with the output shaft of motor 6, is provided with the mechanical seal chamber that mechanical seal 7 is installed 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, import 8 is if there is free air infiltration to go into, and air can be difficult to get rid of always in pump, causes the influence of vertical performance of centrifugal pump.
Summary of the invention
The utility model provides a kind of vertical centrifugal pump of reliable performance at the problems referred to above.
According to the technical solution of the utility model: a kind of vertical centrifugal pump, comprise the pump housing, impeller, pump cover, axle, motor frame and motor, the top of the described pump housing fixedly has described pump cover, described motor frame 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, link to each other with the output shaft of described motor after described axle passes described pump cover, between described pump cover and the described axle mechanical seal is installed; 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.
Fixedly there is pump seat the below of the described pump housing, and the right-angle elbow pipe that is connected with the import of the described pump housing is fixedly arranged in the described pump seat.
Technique effect of the present utility model is: the outlet of the utility model middle pump body is higher than import, even import has little 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 utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Among Fig. 1, Fig. 2, comprise the pump housing 1, impeller 2, pump cover 3, axle 4, motor frame 5, motor 6, mechanical seal 7, import 8, outlet 9, right-angle elbow pipe 10, pump seat 11 etc.
As shown in Figure 2, the utility model is a kind of vertical centrifugal pump, comprises the pump housing 1, impeller 2, pump cover 3, axle 4, motor frame 5 and motor 6.
The top of the pump housing 1 fixedly has pump cover 3, motor frame 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 passes pump cover 3 backs and links to each other with the output shaft of motor 6, between pump cover 3 and the axle 4 mechanical seal 7 is installed.
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 little 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.
