Abstract
The utility model provides a rotary vane of a vacuum pump provided with grooves. At least more than one open groove (2) is disposed on the side of the rotary vane (1) in contact with a pump body, so that dust accumulated in the pump body can be stored in the open grooves (2), and the rotary vane (1) is prevented from being locked in the pump body due to the dust block. In addition, a part of lubricant can be stored in the open grooves (2), so that the lubrication effect between the rotary vane (1) and the pump body can be improved, and the friction therebetween can be reduced. Compared with the prior rotary vane vacuum pump, the rotary vane of the vacuum pump provided with the grooves is applied to the rotary vacuum pump, and has the advantages of low noise, stable performance and long service life. The rotary vane of the vacuum pump adopts novel composite material instead of prior technical material for producing the rotary vane. Therefore, the weight of rotary vane is effectively reduced while the performance of rotary vane is greatly improved.
Description
Technical field
The utility model relates to mechanical type pumping equipment technical field, especially a kind of blade of rotary-vane vaccum pump, particularly a kind of trough of belt Vacuum pump rotary vane.
Background technique
In pumping equipment, rotary-vane vaccum pump is because of simple in structure, compact, the complete machine size is little, part is few, and its functional reliability height, and is easy to use, for ease of maintenaince, the volumetric efficiency advantages of higher is the widest vacuum pump of present using scope, has been widely used in various fields such as chemical industry, electronics, metallurgy and medicine.
Rotary-vane vaccum pump mainly is made up of rotor, the pump housing (stator), blade, and rotor eccentricity places the pump housing (stator), and the blade that is arranged on the rotor center line is divided into two-part with the volume in the pump housing (stator).Its working principle is: power offers rotor, and rotor rotation and driving blade rotate synchronously; A part of volume in the pump housing (stator) increases gradually, and bleeds simultaneously, and another part volume diminishes gradually, and carries out exhaust simultaneously, and circulation and so forth is to obtain the degree of vacuum of expection.
As depicted in figs. 1 and 2, the blade that present rotary-vane vaccum pump uses is rectangular, and contacting with the column type pump housing (stator) is a rectangular surfaces.Dust stuck phenomenon occurs more easily in the pump housing.
In addition, in rotary-vane vaccum pump, blade, the pump housing (stator) cast iron or the steel of adopting are sliding friction between the two more.The full contact of the rectangular surfaces formula of blade between the pump housing more is easy to generate bigger wearing and tearing and mechanical loss, and noise was very big when not only rotary-vane vaccum pump used, and damage easily, influences the working efficiency and the working life of complete machine.
Summary of the invention
The utility model is to solve the problem of above-mentioned existence, and a kind of novel trough of belt Vacuum pump rotary vane is provided, and has many deficiencys to solve existing rotary-vane vaccum pump.
In order to reach described purpose, the trough of belt Vacuum pump rotary vane that the utility model provides, the side that its described blade contacts with the pump housing is provided with at least more than one opening slot.
Trough of belt Vacuum pump rotary vane of the present utility model, because of having a plurality of opening slots on its blade, the dust that accumulates in the pump housing can be stored in the opening slot, and blade is stuck in the pump housing because of dust stops when having avoided operation.
In addition, the blade of trough of belt vacuum pump of the present utility model, because of its blade has a plurality of opening slots, a part of lubricant oil can be stored in these opening slots, and the lubrication effect between the blade and the pump housing is improved, and friction has between the two reduced.
Obviously, trough of belt Vacuum pump rotary vane of the present utility model is because of its blade has a plurality of opening slots, the quality of blade has alleviated, the corresponding minimizing of centrifugal force when therefore rotating, the driving force that can save rotary-vane vaccum pump has also reduced rotary-vane vaccum pump operation noise simultaneously.In addition, because of the blade of rotary-vane vaccum pump has a plurality of opening slots, blade has formed non-comprehensive engagement between the pump housing, reduced friction area.Trough of belt vacuum blade of the present utility model adopts advanced composite material (ACM), has replaced the technologic material of original manufacturing blade, has therefore alleviated the weight of blade effectively, but simultaneously the performance of blade has been greatly improved.
Therefore, trough of belt Vacuum pump rotary vane of the present utility model is applied to rotary-vane vaccum pump, compares with existing rotary-vane vaccum pump, and throat sound is little, stable performance, life-span are long.
Through detecting repeatedly, the opening slot of blade is a semi-circular shape and along the length direction of blade when uniform, the effect of trough of belt Vacuum pump rotary vane of the present utility model more.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the plan view of the blade of existing rotary-vane vaccum pump.
Fig. 2 is the plan view of the blade of existing rotary-vane vaccum pump.
Fig. 3 is the plan view of trough of belt Vacuum pump rotary vane of the present utility model.
Fig. 4 is the plan view of trough of belt Vacuum pump rotary vane of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 3 and Figure 4, the side that trough of belt Vacuum pump rotary vane 1 contacts with the pump housing has three semicircular opening slots 2 along the length direction of blade 1, and the span of three opening slots 2 equates, is distributed in the length direction of blade 1.
After having three opening slots 2 on the blade 1, the dust that accumulates in the pump housing can be stored in the opening slot 2, and blade is stuck in the pump housing because of dust stops when having avoided operation.A part of lubricant oil can be stored in these opening slots 2 simultaneously, and the lubrication effect between the blade and the pump housing is improved, and friction has between the two reduced.
More than be one of mode of execution of the present utility model,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize the purpose of this utility model equally for those skilled in the art.But this variation obviously should be in the protection domain of claims of the present utility model.
Claims (3)
1. trough of belt Vacuum pump rotary vane, it is characterized in that: the side that described blade (1) contacts with the pump housing is provided with at least more than one opening slot (2).
2. trough of belt Vacuum pump rotary vane as claimed in claim 1 is characterized in that, the quantity of described opening slot (2) is three, and is uniform along the length direction of described blade (1).
