Momwe mungachotsere ndikudutsa mumlengalenga woteteza zingalowe m’mlengalenga ng’anjo

M’nyengo yozizira kwambiri yochizira kutentha, zida zina ziyenera kutsukidwa ndikudutsa zodzitchinjiriza kuchita zoyeserera, ndiye kuti njirayi iyenera kugwiritsa ntchito ng’anjo ya vacuum. Koma kodi mukudziwa momwe ng’anjo ya m’mlengalenga imatulutsiramo komanso momwe mpweya umatulutsira mpweya? Ndiroleni ndikuuzeni izi:

1. Kupukuta. Vacuuming imatha kugawidwa kukhala vacuum yochepa komanso vacuum yayikulu. Njira zenizeni ndi izi:

1. Kutsekemera kwapang’onopang’ono: kutseka ma valve onse mwamphamvu, yambani mpope wamakina, dikirani kuti iziyenda bwino (pafupifupi 1-2min), tsegulani valve yotsika yomwe imatsogolera ku ng’anjo ya ng’anjo ya ng’anjo ya ng’anjo, yomwe ili pamwamba pa disc. valavu, ndi kugwirizanitsa ng’anjo thupi pasadakhale Low vacuum.

2. Mpweya wapamwamba: Tsegulani chimbale chapansi ndikupopa mpope wa diffusion. Pamene vacuum ifika 15 Pa kapena kuchepera, yatsani mpope woyatsira kuti muyambe kutentha. Nthawi zambiri, patatha pafupifupi mphindi 45, mpope wa diffusion umayamba ntchito yake, ndiyeno valavu yapamwamba ya disc imatha kutsekedwa. Panthawi imodzimodziyo, tsegulani valavu yayikulu yotchinga ndikudikirira mpaka digiri ya vacuum yasankhidwa ku 1.33 × 10 mpaka -1 mphamvu Pa kapena zambiri, ndiye batani lotenthetsera limatha kutsegulidwa kuti liwotche chitsanzo. Vacuum gauge ili ndi magawo awiri, otsika vakuyumu osiyanasiyana 1.0 × 10 mpaka 5 mphamvu -1.0 × 10 mpaka -1 mphamvu; mkulu vakuyumu osiyanasiyana 1.0 × 10 mpaka -1 mphamvu 1.0 × 10 ku -5 mphamvu, General Yambani kusintha osiyanasiyana pa 2Pa. Zindikirani kuti chojambulira cha vacuum gauge chiyenera kuzimitsidwa musanadzaze mlengalenga kuti chopimira chotchinga chisakalamba.

Popopera vacuum, chonde dziwani kuti valavu yapamwamba ya disc ndi valavu yaikulu yotchinga ya ng’anjo ya vacuum atmosphere sangathe kutsegulidwa nthawi imodzi.

Chachiwiri, kudzera mumlengalenga woteteza

1. Tsegulani valavu yoyendetsera njira ya gasi yapamwamba ndipo pangani batani la batani kumalo “otseguka”.

2. Sinthani knob ya flowmeter kuti kuwerenga kukhale 20ml/min.

3. Tsegulani valavu yolowera mpweya ya ng’anjo ya vacuum atmosphere mpaka barometer iwerenge ziro. Ndipo tsegulani valavu yotulutsira panjira yoteteza mpweya.

Wopanga ng’anjo ya vacuum atmosphere amakumbutsa kuti ng’anjo ya vacuum atmosphere imangotenthedwa pambuyo poti mpweya woteteza wadutsa kwa mphindi khumi.
