(4), slowly open the air-inlet of vacuum pump switch, connecting line is vacuumized, check the impermeability of connecting line according to the vacuum tightness situation of change;
(5), constant temperature switch 13 is pulled to " vacuumize shelves ", 17 pairs of sampling jars 5 of heating element and the Drexel bottle 4 in sampler this moment heated;
(6), then operating grip 11 is threaded to " gas washing " shelves, external equipment connector 2, wireway 7, multiport valve 6, wireway 8 and Drexel bottle 4 are communicated with, Drexel bottle 4 is vacuumized, and when approximately certain hour final vacuum degree reached regulation, Drexel bottle 4 vacuumized complete;
(7), again operating grip is revolved 11 to " sampling " shelves, external equipment connector 2, wireway 7, multiport valve 6, wireway 9 and sampling jar 5 are communicated with, sampling jar 5 is vacuumized, when pressure vacuum gauge is shown as authorised pressure, continue again to take out a few minutes to vacuum tightness when dropping to the authorised pressure left and right, sampling jar 5 vacuumize complete, then with operating grip 11 rotation to " closing shelves ", then close vacuum pump;
(8), sampler vacuumizes and external equipment connector 2 should be put dustproof pipe cap after qualified, with sampler surface wiped clean, and sampler is positioned in suitcase;
(9), application of vacuum finishes, and in time fills in the vacuum pumping release, puts into the clip closed condition.
Can carry out the test of hydrogen fluoride gas colorimetric and gas sample operation after vacuumizing operation and completing, concrete steps are:
(1) sample tap of exact connect ion sulfur hexafluoride electrical equipment to the external equipment connector 2 of sampler, guarantees impermeability;
(2), new hydrogen fluoride color comparison tube 25 is carried out opening and cut off processing;
(3), will be the hydrogen fluoride color comparison tube 25 of opening be arranged on test tube device 23 and lower test tube device 24, during installation, the direction of arrow of hydrogen fluoride color comparison tube 25 is down.Hydrogen fluoride color comparison tube 25 is disposable, installs and uses after holding successfully mouthful, and new hydrogen fluoride color comparison tube 25 need be installed when using at every turn at once;
To be put in without an end of arrow in lower gas passage 51 when (4), hydrogen fluoride color comparison tube 25 is installed, a hand is gently pressed downwards, lower motion bar 49 overcomes the elastic force of the 4th spring 52, and lower motion bar 49 lower end unseat the valve cores 50 make lower gas passage 51 be communicated with Drexel bottle 4;
The another hand upwards gently draws test tube handle 26, in drive, motion bar 45 overcomes the elastic force of the 3rd Compress Spring 47, hydrogen fluoride color comparison tube 25 is vertically placed, unclamp again test tube handle 26, hydrogen fluoride color comparison tube 25 arrow ends are put in gas passage 46, then pinching hydrogen fluoride color comparison tube 25 middle part left rotation and right rotation with finger, that it is aligned is straight, makes air-flow guiding arrow outwardly, and hydrogen fluoride color comparison tube 25 installs;
(5), operating grip 11 is threaded to " hydrogen fluoride test shelves ", external equipment connector 2, wireway 7, multiport valve 6, wireway 10 and hydrogen fluoride color comparison tube 25 are communicated with, then slowly open external equipment sample tap valve and sample gas is arranged by getting final product, throttling valve 27 play vacuumize or when taking a sample gas keep the effect of constant rate under certain pressure, timing about a few minutes, namely complete hydrogen fluoride test (do not need to carry out the hydrogen fluoride test as the scene of taking a sample, operating grip 11 directly is threaded to " gas washing shelves " and carries out gas washing and get final product);
(6), with operating grip 11 dextrorotations to " gas washing shelves ", after timing some seconds, complete gas washing (carried out the hydrogen fluoride test as the scene of taking a sample, need not carry out gas washing, can directly handle be threaded to the sampling shelves and carry out sampling operation);
(7), (or after carrying out the hydrogen fluoride test) after gas washing, operating grip 11 is threaded to " sampling shelves ", when the sampler pressure gauge shows that demonstration reading with sampled electrical equipment pressure gauge is identical, 11 dextrorotations of sampler operating grip to " close shelves " position, are then closed sampling air intake valve on electrical equipment, removed the sampling inlet pipe connection;
(8), take after sample gas, the sampler external interface to be put dust cap, with sampler surface wiped clean, be positioned in suitcase;
(9), gas sample finishes, with the sampling record card filled in, put into the clip closed condition.
After sampling, carry out laboratory gas sample stratographic analysis step as follows:
(1), be connected and lock by decompressor, the assurance impermeability in the middle of the external equipment connector 2 that will fill sample gas and chromatograph interface;
(2), the socket of sampler 15 connects the 220V power supplys, closed electrical source switch, and constant temperature switch 13 is pulled as for " chromatogram shelves " state;
(3), the chromatograph preheating, approximately about 30 minutes, chromatograph is in normal operating conditions in timing;
(4), press the non-return button 33 of the stratographic analysis indication on sampler, non-return button 33 moves down by the elastic force that non-return connecting link 38 drive register pins 34 overcome the second Compress Spring 40, register pin 34 and latch bolt 42 move down, when latch bolt 42 during lower than the dial plate 41 of operating grip 11 bottom surfaces, register pin 34 no longer stops dial plate 41, so just operating grip 11 can be threaded to counterclockwise " sampling shelves " position, can carry out stratographic analysis;
(5), after the laboratory chromatogram detects and completes, successively sampler constant temperature switch 13 is pulled as for " close shelves ", operating grip 11 dextrorotations to " close shelves ", disconnect the sampler power switch, print and preserve the detection data, close the chromatograph switch at last, stratographic analysis is completed;
(6), stratographic analysis should put pipe cap with the sampler external interface after complete, with sampler surface wiped clean, be positioned in suitcase.
The present invention in use should be noted that following item:
(1), transpassivation of connecting tube, protective treatment between inner each parts of sampler, forbid dust, dirty entering.
(2), keep sampler surface clean, clean and tidy, answer wiped clean after each the use, and in time be put in suitcase.
(3), when sampler is not used, external equipment connector 2 should in time put the sealing and dustproof cap, loads onto used hydrogen fluoride color comparison tube 25 at upper test tube device 23 and lower test tube device 24.
(4), sampler belongs to cleaning apparatus, should note waterproof and dustproof and protection against the tide.
(5), sampler vacuumizes and the external power supply of should pegging graft when carrying out sample complexion analysis of spectrum, notices that constant temperature switch 13 selects shelves, must not mistake and mix up.
(6), sampler for a long time not the clean dry nitrogen of used time application of pure rinsed, and the nitrogen that is filled with the certain pressure clean dry in sampling jar is sealed up for safekeeping.
