Kusankhidwa kwa mtundu wamakina osindikizira ndi gawo lofunikira pamapangidwe, kuyenera kufufuzidwa poyamba:
1.Working magawo -Kuthamanga kwa Media, kutentha, shaft m'mimba mwake ndi liwiro.
2. Sing'anga makhalidwe - ndende, mamasukidwe akayendedwe, causticity, kapena opanda tinthu olimba ndi CHIKWANGWANI zonyansa, kaya n'zosavuta nthunzi kapena crystallization.
3. Makhalidwe ogwirira ntchito ndi momwe chilengedwe chimakhalira - kugwira ntchito kosalekeza kapena kwapang'onopang'ono; Wolandirayo amaikidwa m'chipindamo kapena poyera; Makhalidwe ozungulira ndi kusintha kwa kutentha.
4. Gulu la chisindikizo kuti lilole kutayikira, mayendedwe otayikira (kutuluka kwamkati kapena kutayikira kwakunja) zofunika; Moyo ndi kudalirika zofunika.
5. Khazikitsani kukula kwa zoletsa zosindikizira.
6. Kukhazikika kwa ntchito ndi kupanga ndondomeko.
Choyamba, malinga ndi magawo ogwira ntchito P, V, T kusankha:
Apa P ndiye kuthamanga kwapakatikati pamkati mwa chisindikizo. Kutengera kukula kwa mtengo wa P, zitha kutsimikiziridwa poyambirira ngati kusankha kapangidwe koyenera komanso kuchuluka kwake.Kwa kukhuthala kwapakatikati, kutsekemera kwabwino, p ≤ 0.8MPa, kapena kukhuthala kotsika, kutsika bwino kwapakati, p ≤ 0.5MPa, nthawi zambiri amagwiritsa ntchito mawonekedwe osayenerera.Pamene mtengo wa p ukupitirira malire omwe ali pamwambawa, ndondomeko yoyenera iyenera kuganiziridwa.Pamene P ≥ 15MPa, mawonekedwe amtundu umodzi wamtundu umodzi ndi ovuta kukwaniritsa zofunikira zosindikizira, nthawi ino. angagwiritsidwe ntchito mndandanda multi-terminal chisindikizo.
U ndiye liwiro lozungulira la kukula kwapakati pa malo osindikizira, ndikuwunika ngati chinthu chotanuka chimazungulira ndi olamulira malinga ndi mtengo wa mtengo wa U, womwe ukugwiritsa ntchito makina ozungulira amtundu wa masika kapena odzaza masika. zosakwana 20-30m / s zingagwiritsidwe ntchito kasinthasintha wamtundu wa kasupe, mikhalidwe yothamanga kwambiri, chifukwa cha khalidwe losasinthasintha la magawo ozungulira mosavuta kumapangitsa kugwedezeka kwamphamvu, ndi bwino kugwiritsa ntchito kasupe wosasunthika.Ngati mtengo wa P ndi U onse ndi okwera, ganizirani kugwiritsa ntchito mawonekedwe a hydrodynamic.
T imatanthawuza kutentha kwa sing'anga mu chipinda chosindikizidwa, malinga ndi kukula kwa T kuti adziwe mphete yothandizira yosindikiza, njira yosindikizira pamwamba pa kuzizira ndi dongosolo lake lothandizira. Kutentha T pa 0-80 ℃ osiyanasiyana, mphete yothandizira ndi Nthawi zambiri amasankhidwa nitrile rabara O-ring; T pakati -50 — +150 ℃, malinga ndi mphamvu zowononga za media, kusankha mphira wa fluorine, mphira wa silikoni kapena mphete ya PTFE yonyamula zodzaza zilipo. Kutentha kumakhala kotsika kuposa -50 kapena apamwamba kuposa 150 ℃, mphira ndi polytetrafluoroethylene adzatulutsa otsika kutentha embrittlement kapena kutentha kukalamba ukalamba, nthawi ino angagwiritsidwe ntchito zitsulo mvuvu structure.When turbidity wa sing'anga ndi apamwamba kuposa 80 ℃, nthawi zambiri m'pofunika kuganizira ngati mkulu kutentha m'munda wosindikizira, ndipo njira zoziziritsira zofanana ziyenera kuchitidwa.
Sekondale, zosankhidwa motengera mawonekedwe a media:
Sing'anga yofooka yowononga, nthawi zambiri imagwiritsa ntchito chisindikizo chomangidwira, kutha kwa mphamvu komanso komwe kutayikira kwapa media kumakhala koyenera poyerekeza ndi mtundu wakunja. Kwa media zowononga zolimba, chifukwa kusankha zinthu zamasika kumakhala kovuta kwambiri, mutha kugwiritsa ntchito. kunja kapena polytetrafluoroethylene mvuvu mawotchi makina chisindikizo, koma kawirikawiri ntchito P ≤ 0.2-0.3MPa range.Easy crystallize, zosavuta kulimbitsa ndi mkulu mamasukidwe akayendedwe sing'anga, ayenera kugwiritsa ntchito kasupe rotary structure.Chifukwa akasupe ang'onoang'ono amatsekedwa mosavuta ndi zolimba, media media zidzachititsa yaing'ono kasupe axial chipukuta misozi kayendedwe otsekeka.Kuyaka, kuphulika, poizoni TV, pofuna kuonetsetsa kuti TV si kutayikira, kamangidwe kaŵirikaŵiri ndi sealant (kudzipatula madzi) ayenera kugwiritsidwa ntchito.
Malinga ndi magawo omwe akugwira ntchito pamwambapa komanso mawonekedwe amtundu wazomwe amasankhidwa nthawi zambiri amakhala pulogalamu yoyambira, kutsimikiza komaliza kuyeneranso kuganizira za mawonekedwe a wolandila komanso zofunika zina zapadera zosindikizira.Mwachitsanzo, wokhala m'sitima nthawi zina amakhala kuti mupeze malo abwino kwambiri, kukula kwa chisindikizo ndi malo oyikapo nthawi zambiri zimakhala zofunikira kwambiri.Chitsanzo china ndi sitima yapamadzi pa mpope wa ngalande, mukukwera ndi kutsika kwa sitima zapamadzi, kupanikizika kumasiyana kwambiri. , dongosolo lokhazikika silingasankhidwe pafupipafupi, koma liyenera kupangidwa mwapadera kuti ligwirizane ndi momwe ntchito ikugwirira ntchito, ndikuchitapo kanthu kofunikira.
