Description

Centrifuge variable water outlet control device

Technical Field

The utility model relates to a centrifuge field especially relates to a centrifuge variable goes out water controlling means.

Background

The water outlet channel of the water outlet device of the existing centrifugal machine is equal to the diameter of the edge from the center, the water yield is constant, the water flow is turbulent, the water flow forms huge pressure impact on a rotating water cavity, a part of pressure can be lost after the water flow flows out of the cavity, and the service life of the device can be shortened by long-time high-pressure impact. Due to the diameter limitation of the existing pump impeller, the existing problem cannot be solved by changing the form of the aperture size.

Disclosure of Invention

In order to solve the problem, the utility model discloses a centrifuge variable goes out water controlling means, the device utilize eccentric rotor's principle to set up outlet channel into the form that increases in proper order to the periphery from the center, reduce the impact force of rivers to the cavity wall, extension fixture life.

The utility model provides a centrifuge variable goes out water controlling means, includes rotatory water cavity, the drive shaft is equipped with to rotatory water cavity endotheca, be provided with the centripetal pump wheel in the rotatory water cavity, the centripetal pump wheel is eccentric structure, the centripetal pump wheel is provided with axial inhalant canal and radial exhalant canal, the sectional area of exhalant canal is increased to the edge by the center of centripetal pump wheel in proper order, exhalant canal is arc setting along the rivers direction.

Preferably, the radial direction of the circular arc from the center to the edge is opposite to the rotation direction of the centripetal pump wheel.

Preferably, a fixing pin for fixing the centripetal pump wheel is arranged between the centripetal pump wheel and the driving shaft.

Preferably, the centripetal pump wheel is further provided with a stirring pin for driving the pump wheel to rotate, and the stirring pin is connected with the water supply pipe.

The utility model has the advantages that:

the utility model discloses a set up the sectional area of exhalant canal by the center to the eccentric formula centripetal pump that the edge increases in proper order, realized the decompression of rivers and carried, the water yield is even, reduces pressure impact, improves device life.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it should be understood that the terms "inside", "outside", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The utility model discloses a centrifuge variable play water controlling means as shown in fig. 1-2, 6 suits of delivery pipe are outside at drive shaft 7, and the left flange of terminal installation of delivery pipe installs the right flange in the drive shaft, and centripetal pump impeller 2 is located between two flanges, and this centripetal pump impeller is eccentric structure, and centripetal pump impeller is provided with axial inhalant canal and radial exhalant canal 4, inhalant canal and delivery pipe intercommunication. The sectional area of the water outlet channel is sequentially increased from the center to the edge of the centripetal pump wheel, the water outlet channel is arranged in a circular arc shape along the water flow direction, and the radiation direction of the circular arc shape from the center to the edge is opposite to the rotation direction of the centripetal pump wheel. The right flange outside sets up rotatory water cavity 1, and a plurality of delivery ports are evenly arranged to the circumference of rotatory water cavity, and the direction of delivery port leans out the setting by the center along the cavity outer wall.

The centripetal pump wheel 2 is connected with a right flange arranged on a driving shaft 7 through a fixed pin 3, and the centripetal pump wheel is connected with a left flange at the tail end of a water supply pipe 6 through a stirring pin 5. The driving shaft drives the centripetal pump wheel to rotate, the water supply pipe rotates to stir the centripetal pump wheel, and the rotation speed difference exists between the driving shaft and the water supply pipe, so that the rotation water supply of the centripetal pump is realized.

The device utilizes the principle of the eccentric rotor to set the water outlet channel into the eccentric centripetal pump with the sectional area which is sequentially increased from the center to the edge, thereby realizing the decompression delivery of water flow, ensuring uniform water yield, reducing pressure impact and prolonging the service life of the device.
