Abstract

The utility model relates to a swirl pump, belonging to a miniature pump which is used for pressurizing a line pump in a household. The water inlet pipe and the water outlet pipe of the utility model are extended upwards and reversely from a water inlet and a water outlet which are arranged at the radial position of a pump chamber, and the centerlines of the water inlet pipe and the water outlet pipe are coincident. The utility model has the advantages that the water inlet pipe and the water outlet pipe are positioned on the same straight line, when pipe passages are butted, no elbow is required, the installation is easy, and the arrangement of the pipelines is beautiful; after a pump body turns 180 DEG to be installed on an electric motor, the distance between the centerlines of the water inlet pipe and the water outlet pipe, and a foot rack has two types to be selected, and therefore, the adaptability of the pump to the pipelines is stronger.

Description

Swirl pump

The utility model relates to a kind of peripheral pump that family expenses pressure pipeline pump uses of doing.

Peripheral pump has an important structure characteristic, is exactly the radial position that water intake and water outlet are arranged on pump chamber, and two mouthfuls adjoint, and middle is separated by with cut water, and the intake pipe of outwards drawing from water intake and water outlet and the center line of outlet pipe are parallel to each other.This peripheral pump is installed, and when implementing intake pipe and outlet pipe with inlet pipeline and rising pipe butt joint, every pipeline all needs to do 90 ° of turnings, adopt one to two elbow in supply channel.Therefore, the installation of pipeline is cumbersome and not attractive in appearance.

The purpose of this utility model provides a kind of peripheral pump of doing the use of family expenses pressure pipeline pump easy for installation.

Solution of the present utility model reverse the stretching out that be intake pipe and outlet pipe on water intake that is arranged on the pump chamber radial position and the water outlet, and the central lines of intake pipe and outlet pipe.

Further illustrate detailed content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: structural drawing of the present utility model;

Fig. 2: A-A sectional view.

The peripheral pump that uses as family expenses pressure pipeline pump is a kind of micropump, generally be that the pump housing is directly installed on the front cover of motor, and directly utilize motor shaft to make pump shaft 1, the pump housing is by pump seat 2, pump cover 3, the dynamic seal apparatus of impeller 4 and axle is formed, between pump seat 2 and pump cover 3, form the pump chamber 5 that holds impeller 4, water intake 6 and water outlet 7 are arranged on the radial position of pump chamber 5, and the cut water 8 that is stretched in the pump chamber 5 is separated, intake pipe 9 and outlet pipe 10 reverse stretching out on water intake 6 and the water outlet 7, and the center line 11 of intake pipe 9 and outlet pipe 10 and 12 overlaps, on structural design, intake pipe 9 and outlet pipe 10 can be placed on the pump seat 2, also can be placed on the pump cover 3, present embodiment adopts back one scheme, be that intake pipe 9 and outlet pipe 10 are arranged on the pump cover 3, in view of the above, cut water 8 also should be arranged on the pump cover 3.In addition, the dynamic seal apparatus of axle is varied, and present embodiment adopts mechanical seal device 13.

The peripheral pump of said structure has following advantage. The one, water inlet pipe and outlet pipe when pipeline joint, needn't use elbow point-blank, and be easy for installation, and line arrangement is attractive in appearance; The 2nd, the pump housing turn 180 ° be installed on the motor after, the center line that makes water inlet pipe and outlet pipe to the distance of foot rest has two kinds, and is available, like this, the adaptability that pump is installed pipeline is also just stronger.

Claims

1, a kind of peripheral pump of doing the use of family expenses pressure pipeline pump, it is characterized in that: intake pipe (9) and outlet pipe (10) are gone up reverse stretching out from the water intake (6) and the water outlet (7) that are arranged on pump chamber (5) radial position, and the center line (11,12) of intake pipe (9) and outlet pipe (10) overlaps.
