Embodiment
This high vacuum double end air exhauster as shown in the figure, form by frame 1, liquid nitrogen cooling system 2, quick lock head component 3, clamp assembly 4, air-channel system 5, pipe-line system 6, extract system 7, electrical system 8, gas burning system 9, comparing with overseas like product, its inventive improvements mainly are to be embodied in following four aspects:
One, adopt the quick tapered end combining structure of new high vacuum, quick lock head component 3 directly is locked at clamp assembly 4 bottom faces, this quick lock head component 3 partly is made up of fluorescent tube blast pipe locking device and the switching device two be located on the same valve body 14, and fluorescent tube blast pipe locking device wherein is located at inside and outside valve body 14 lower chamber; Mainly by spacer 15, sealing shroud 13, end last item hold 12, packing ring 11, locking nut 10 etc. form, described spacer places valve pocket topmost, the height of deciding that is used for blast pipe 23, the locking of blast pipe 23 is then made it promote packing ring 11 and is held last item to hold 12 by rotational lock nut 10 and moves up, thereby sealing shroud 13 compressions are reached hold blast pipe tightly, the purpose of sealing blast pipe; Described switching device then places valve body 14 tops one side, this device is mainly by stirring the handle 22 of a band cambered surface with hand, make it to produce horizontal displacement by the slide-bar 20 that links to each other with a bearing pin 21, thereby make the sealing ring 16 under stage clip 18 effects realize compressing or stretching, make the breeder tube of sealing circle and valve body 14 sides open the closed conducting and cut-out function that realizes whole vacuum system.
Its two, class tool assembly is carried out inventive improvements, this clamp assembly 4 is made up of the hoisting mechanism and the fluorescent tube blast pipe seal-locking mechanism that are installed on the support plate 47; Described hoisting mechanism is by means of the handgrip of forming in one of member 56 that is provided with on the shape lock bracket 50 that turns, and cooperate bearing pin I59, bearing pin III57 to be connected with support plate 47, locking support plate 49, left supported plate 54, right supported plate 58 respectively, make horizontal support plate 53 that is connected with this cylinder expansion link and the left supported plate that matches under the effect of cylinder 45, right supported plate is realized moving horizontally; Thereby drive the swing of lock bracket 50, impel on the locking support plate 49 that is attached thereto and move, and move on the drive lifting cover 51 around bearing pin I59.Described fluorescent tube blast pipe seal-locking mechanism, by clamp body 48 be located at packing ring 60 in the clamp body bottom cavity, sealing shroud 61, plain cushion 62 etc. and form, the packing ring 60 that is equipped with the stainless steel cloth interlayer wherein places the interior top of cavity, and next coming in order are sealing shroud 61 and plain cushion 62.Just because of moving plain cushion 62 crush seals cover 61 distortion of the last shipper pole of lifting cover 51 in the hoisting mechanism, the purpose that finally causes holding tightly blast pipe.
Its three, molecular pump 33 direct levels are connected in the pipe-line system, adopt cutting ferrule to connect, both can shorten the distance of molecular pump and pipe-line system, gas clean-up and pumping speed make maintenance more simple and direct again.
They are four years old, by being located at the rack table plate about 43, by liquid nitrogen cup 42, cylinder 39, the liquid nitrogen cooling system that slide block 40 and push rod 41 are formed makes the processing bulb in filling exhaust, burned tip, sealing process, liquid nitrogen was cooled off glass bulb, simultaneously the gas that charges into cell-shell is chilled in the bulb spheroid fully, improves the utilance of filling the air inlet body very effectively, can very reduce the bulb production cost effectively.
In the above-mentioned air exhauster use, pipeline charges into gas bleed twice, then the gas that charges into is in time taken away with forepump, charges into fluorescent tube again and starts gas, and its technical process is as follows:
Fore line---essence is taken out pipeline---charging into flushing gas---, and forepump is taken away, and fore line, and---essence is taken out pipeline---charging into flushing gas---, and take away, and fore line---essence is taken out pipeline---charges into fluorescent tube startup gas by forepump.
Concrete operations are as follows:
Press start button, forepump (30) fore pump (35) is opened, and pneumatic operated valve (34), pneumatic operated valve (28), pneumatic operated valve (34) are closed, and other pneumatic operated valve is opened---fore line.When the system vacuum degree reached the pressure limit of molecular pump work, pneumatic operated valve (34) was opened; Air valve (31) is closed, and other pneumatic operated valve is kept original state.Molecular pump is opened---and essence is taken out pipeline.The molecular pump system vacuum degree that works on reaches and sets when being used for the vacuum degree of gas bleed pipeline, and pneumatic operated valve (28) is opened; Pneumatic operated valve (34) cuts out.Other pneumatic operated valve is kept original state---charge into flushing gas.When charged pressure reaches the vacuum gauge set point, the automatic sender of vacuum gauge, pneumatic operated valve (28) cuts out, and pneumatic operated valve (31) is opened, and other pneumatic operated valve is kept normality---and the gas that charges into is in time taken away by forepump, and fore line, the preparation pump works on.When the system vacuum degree reaches the pressure limit of molecular pump work, the automatic sender of vacuum gauge.Pneumatic operated valve (34) is opened, and pneumatic operated valve (31) cuts out, and other pneumatic operated valve is kept original state---charge into flushing gas.Pneumatic operated valve (34) cuts out.Other pneumatic operated valve is kept normality; Then charge into fluorescent tube and start gas.In above-mentioned technical process, the normal pressure data that charge into gas are regulated collection by malleation, and the negative pressure data are regulated collection by negative pressure, and show through public display unit; And the amount that charges into fluorescent tube gas is by being installed in ducted volumetric bottle adjustment; When the liquid nitrogen cup rises cooling fluorescent tube spheroid, make to charge into gas and be chilled in fully in the fluorescent tube spheroid, finally finish sealing process.
