Description
Technical field
The utility model belongs to field of vacuum, especially a kind of membrane pump with pneumatic drive.
Background technique
The direction of existing diaphragm pump upper and lower covers outlet is fixing, such as import or export direction left or to the right, cause sometimes and difficulty is installed, use inconvenience, need the extra device installing change media flow direction, thus considerably increase user cost, and this stationary structure cannot be applied in a flexible way in actual use; Therefore should improve prior art.
Summary of the invention
For the problems referred to above, the utility model aims to provide a kind of easy to use, membrane pump with pneumatic drive that flexibility is good.
For realizing this technical purpose, the utility model provides following technological scheme:
A kind of membrane pump with pneumatic drive, comprise external flange, upper cover, the pump housing, lower cover, flange support tube and flange, bilateral symmetry above the described pump housing is provided with upper cover, and the bilateral symmetry below the pump housing is provided with lower cover, connected by flange support tube between described two upper covers, connected by flange support tube between described two lower covers, described upper cover and flange support tube joint and lower cover and flange support tube joint are equipped with flange.
As further program of the utility model: be equipped with external flange outside described two flange support tubes, and the pump housing is connected with installation place by external flange.
As further program of the utility model: described external flange changes installation direction along with the rotation of flange support tube, makes the import or export of the pump housing any one direction in the upper and lower four direction in front and back.
Compared with prior art, the beneficial effects of the utility model are: upper cover and external flange joint adopt NBS flange size, not only can acting flange separately, a diaphragm pump is used as two pumps, and the installation direction of external flange can be changed, outlet is upper and lower four direction before and after can selecting, thus more simple, more convenient to use for installing.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure: 1-external flange, 2-upper cover, the 3-pump housing, 4-lower cover, 5-flange support tube, 6-flange.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of membrane pump with pneumatic drive, comprise external flange 1, upper cover 2, the pump housing 3, lower cover 4, flange support tube 5 and flange 6, bilateral symmetry above the described pump housing 3 is provided with upper cover 2, and the bilateral symmetry below the pump housing 3 is provided with lower cover 4, connected by flange support tube 5 between described two upper covers 2, connected by flange support tube 5 between described two lower covers 4, described upper cover 2 is equipped with flange 6 with flange support tube 5 joint and lower cover 4 with flange support tube 5 joint, external flange 1 is equipped with outside described two flange support tubes 5, and the pump housing 3 is connected with installation place by external flange 1, described external flange 1 is along with the rotation change installation direction of flange support tube 5, make the import or export of the pump housing 3 any one direction in the upper and lower four direction in front and back.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
