Abstract
The utility model discloses a kind of fine pumping system, comprise body, body cover plate, extraction pump, stem tracheae and afterbody tracheae, described extraction pump is fixed on body cover plate, described extraction pump is connected with stem tracheae one end, stem tracheae and afterbody tracheae one end all have and the stem gas-tpe fitting of plane-parallel and afterbody gas-tpe fitting, stem gas-tpe fitting horizontal plane is concordant with body upper surface or lower than body upper surface, when described body cover plate covers on body, described stem tracheae forms tightness at described stem gas-tpe fitting place with afterbody gas-tpe fitting with afterbody tracheae and is connected.The utility model can save the plenty of time for carrying out two exhaust tube disassemble and assemble works, thus substantially increases manufacturing efficiency.
Description
Technical field
The utility model relates to extract system, especially belongs to vacuum pumping system.
Background technique
At present in vacuum lines, article one, production line often needs tens individual separate vacuum chambers even up to a hundred, gas in vacuum chamber extracts the arm entering both sides out through extraction pump, converged by two side branch again and enter supervisor, discharged by forepumping pump, the problem that the arm relating to extraction pump connection is like this connected with supervisor, the upper cover be positioned at higher than vacuum chamber is responsible for often in prior art, extraction pump connecting branch is connected by metallic hose with supervisor, the each vacuum chamber of such one side needs the metallic hose of arm and the supervisor connected by extraction pump to carry out hand disassembly when upper cover is opened or covered to needs, because a production line often needs tens individual separate vacuum chambers even up to a hundred, require a great deal of time the disassemble and assemble work carrying out the arm of extraction pump connection and the metallic hose of supervisor like this, thus greatly have impact on manufacturing efficiency, and waste a large amount of energy, cost of production is not only caused greatly to improve, nor be beneficial to environmental protection, on the other hand, the arm that extraction pump connects is with to manage interior degree of vacuum higher, and higher to the seal request of joint, the setting of prior art often causes joint to leak gas.
Summary of the invention
The purpose of this utility model is, in order to overcome the shortcomings and deficiencies of prior art, providing that a kind of structure is simple, easy for installation, air-tightness is good, being not easy the fine pumping system of leaking gas.
The purpose of this utility model can reach by taking following technological scheme:
A kind of fine pumping system, comprise body, body cover plate, extraction pump, stem tracheae and afterbody tracheae composition, described extraction pump is fixed on body cover plate, described extraction pump is connected with stem tracheae one end, stem tracheae and afterbody tracheae one end all have and the stem gas-tpe fitting of plane-parallel and afterbody gas-tpe fitting, stem gas-tpe fitting horizontal plane is concordant with body upper surface or lower than body upper surface, when described body cover plate covers on body, described stem tracheae forms tightness at described stem gas-tpe fitting with afterbody gas-tpe fitting place with afterbody tracheae and is connected.
As the preferred embodiment of the utility model patent, described afterbody tracheae is connected with stem gas-tpe fitting by metallic hose, described stem gas-tpe fitting along the circumferential direction has circular shape groove, airtight packing is placed with in circular shape groove, described afterbody tracheae is connected with afterbody gas-tpe fitting by metallic hose, when described body cover plate covers on body, stem gas-tpe fitting and afterbody gas-tpe fitting form tightness and are connected.And stem gas-tpe fitting is concordant with body cap plate junction plane with body with afterbody gas-tpe fitting junction plane.
Compared with prior art, the utility model has the following advantages:
One, the utility model patent fine pumping system is adopted, the connection set manually coming dismounting afterbody tracheae and stem tracheae is not needed during dismounting body cover plate, because a production line often needs tens individual separate vacuum chambers even up to a hundred, the plenty of time of the disassemble and assemble work for carrying out stem tracheae and afterbody tracheae can be saved like this, thus substantially increase manufacturing efficiency.
Two, because the utility model patent pump fine pumping system makes the stem gas-tpe fitting level that is connected with afterbody tracheae, when described body cover plate covers on body, stem gas-tpe fitting forms tightness connection by the effect of gravity, and in the process vacuumized, because afterbody tracheae and stem tracheae all have certain degree of vacuum, the sealing that such stem gas-tpe fitting and afterbody gas-tpe fitting lean on atmospheric pressure self-assembling formation more fastening.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of the utility model fine pumping system.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model fine pumping system comprises body 2, body cover plate 1, extraction pump 3, stem tracheae 4 and afterbody tracheae 5 form, afterbody tracheae 5 is lower than body cover plate 1, afterbody tracheae 5 is connected with stem gas-tpe fitting 7 by metallic hose 6, stem gas-tpe fitting 7 along the circumferential direction has circular shape groove, airtight packing is placed with in circular shape groove, described stem tracheae 4 is connected with afterbody gas-tpe fitting 9 by metallic hose 8, when described body cover plate lid 1 covers on body 2, because afterbody gas-tpe fitting 9 and stem gas-tpe fitting 7 junction plane and body are parallel with body cap plate junction plane be and plane-parallel, afterbody gas-tpe fitting 7 relies on the gravity pressure of stem tracheae 4 and body cover plate 1 on stem gas-tpe fitting 7, simultaneously, stem gas-tpe fitting 7 along the circumferential direction has circular shape groove, airtight packing is placed with in circular shape groove, therefore, stem gas-tpe fitting 7 and afterbody gas-tpe fitting 9 without any need for mechanical connection can form tightness and be connected, make lifting body cover plate very convenient, like this, tens individual separate vacuum chambers even up to a hundred are often needed for a production line, the plenty of time for carrying out afterbody tracheae 5 and stem tracheae 4 disassemble and assemble work can be saved, thus substantially increase manufacturing efficiency, and also save a large amount of energy, cost of production is not only made greatly to reduce, and be conducive to environmental protection.
Simultaneously, in the process of finding time, stem tracheae 4 and afterbody tracheae 5 have certain degree of vacuum, the surface of contact of stem gas-tpe fitting 7 and afterbody gas-tpe fitting 9 can be inhaled tighter and tighter by the pressure of air, the problem of gas leakage can not be produced, like this, a difficult problem for the easy gas leakage of currently available technology is solved well.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore, the equivalent variations done according to the utility model claim, still belongs to the scope that the utility model is contained.
