Problems solved by technology

When the space is annular and the space on either side is small, only a small vacuum pump can be installed, but often its power cannot meet the requirements. At this time, a pump that can make full use of the annular space is needed, because the annular space is fully utilized. , its power will be larger than that of a small pump that only uses one side of the space
In the design of vacuum pumps, there are many forms of vacuum pumps, such as eccentrically rotating rotors or protruding blades or reciprocating pistons. The rotors cannot be hollow in the middle, which is the design principle of the pump currently used. It is impossible to achieve a hollow ring pump in the middle, and it is necessary to use a hollow ring pump in some limited spaces

Embodiment Construction

[0045] The accompanying drawings are all schematic diagrams of the implementation of the present invention, so as to understand the principle of structural operation. The specific product structure and proportional size can be determined according to the use environment and conventional technology.

[0046] like figure 1 , 2 , 3, it includes an annular pump body 1, a drive unit 2 installed on the lower side of the pump body 1 and a locking mechanism 6 installed on the lower side of the pump body 1; The pump body 1 supports and fixes the role; the drive unit 2 drives the rotating parts in the pump body 1 to operate for the purpose of pumping vacuum.

[0047] like figure 2 As shown, the above-mentioned locking mechanism 6 is used for the installed pump body 1 .

[0048] Two air passages 7 are installed symmetrically on the outer surface of the casing of the pump body 1, and the air passages 7 communicate with the inside of the pump body 1. 7. A gas one-way valve is set on ...

Abstract

The invention belongs to the technical field of vacuum pumps, and particularly relates to an annular vacuum pump. The pump comprises an annular pump body, a driving unit mounted on the lower side of the pump body and a clamping mechanism mounted on the lower side of the pump body; the clamping mechanism is used for mounting of the pump body, two air channels are symmetrically mounted on the outercircle face of a shell of the pump body, a rotating driving annular plate is arranged in the pump body, the driving annular plate is circumferentially and alternatively provided with multiple second blocks and multiple first blocks, the driving annular plate can drive the first blocks and the second blocks to rotate in the shell along the center of the pump body to form space changes, and the gasextracting aim is achieved. The hollow annular pump is designed, and can be used in some occasions with the limited space, the annular space is sufficiently used, power is larger than that of a smallpump using space on one side, and the pump can be well used in the annular space.

Description

[0001] Technical field [0002] The invention belongs to the technical field of vacuum pumps, in particular to an annular vacuum pump. Background technique [0003] At present, vacuum pumps have been developed and used in various industries. Through vacuum pumps, the air in a space can be sucked out to generate a certain degree of vacuum state. A general vacuum pump has a solid shape and requires a certain amount of space to place it. When the space is annular and the space on either side is small, only a small vacuum pump can be installed, but often its power cannot meet the requirements. At this time, a pump that can make full use of the annular space is needed, because the annular space is fully utilized. , and its power will be greater than that of a small pump that only uses one side of the space. In the design of vacuum pumps, there are many forms of vacuum pumps, such as eccentrically rotating rotors or protruding blades or reciprocating pistons. The rotors cannot be ...
