The Installation Precautions
Chithunzi cha VJP(paipi ya vacuum)ziyenera kuikidwa pamalo ouma popanda mphepo isanakhazikitsidwe.Theakunjakuyikawosanjikiza wa VJP sangathebe tsegulanied, kuteteza chubu kukhala matupi achilendo (mchenga, zamoyo zazing'ono, etc.). Mvula kapena nthawi yayitalichonyowanyengo, komanso ayenera kulabadira mwapadera mkati mwa payipi madzi.
Ndikoletsedwa kugwiritsa ntchito VJP mwachindunji monga electrode yowotcherera, kugunda arckapena kuwotcherera pa VJP.
Chithunzi cha VJPkuyikawosanjikiza sangathe kuchotsedwa mpaka chitoliro anaika kuteteza kuwonongeka kwa kuwotcherera malo ena.
Panthawi yonse yoyika, VJP iyenera kusamaliridwa bwino. Tetezani mbali zonse ziwiriya VJP, musagwiritse ntchitovacuumophatikizana pa VJP (chithunzi 1 ndi 3) ngati mfundo yoletsa kutayikira kwa vacuum.
Mukayika, samalani ndi kudalirika kwa kukweza, musagwe ndikuwononga kapena kuvulala.
Njira Zoyikira VJP
1. Onanindikujambulas, kaya kuchuluka ndi dimensionza mapaipipa zojambula ndi omwewondindimapaipi akumunda. Bisanakhazikike, pezanikunjaaliyense VJP malinga ndi chojambula ndinambala. Chitsanzo:HL2018GLN-59-02-01, zomwe zikutanthauza kuti nambala ya polojekiti ndi 59, sing'anga ya nayitrogeni yamadzimadzi, chitoliroAyi.01 pa lineAyi.02. Dzina lachitsulo lomwe lili ndi izinambalaimamangiriridwa ku VJP pamalopo (chithunzi 1), ndipo dzina lamagetsi lamagetsi limamangiriridwapafupi ndi cholumikizira cholumikizirandiVJP(chithunzi 2).
Chidziwitso: akuchulukandi No.mipope mu chojambula ayenera kukhala chimodzimodzi ndikuchulukandiAyi.zaZithunzi za VJPkomweko. Ngati pali kusiyana kulikonse pakuwunika, onetsetsani kuti mwalumikizana ndi ogwira ntchito patsamba lathu.
2. Pambuyo pofufuza kuchuluka kwa VJP ndiAyi.,malinga ndi zojambulazo, sunthandi VJPspa bulaketi yolinganas/zothandizirakapena maloZithunzi za VJPpansi pafupi ndi bulaketi lolinganas/zothandizira.
3. Ma flange asanalumikizidwe, choyamba yang'anani ngati mphete zosindikizira ndi chisindikizo chozizira zaikidwa bwino.
4. Tsukani mfundo zamkazi & mwamunakuwonjezerachitoliro, chisindikizomphetendi chipinda chosindikizira chozizira chokhala ndi mafuta opanda mafuta komanso opanda madzi.
5. Lowetsani chitoliro chachimuna ndi chachikazi molunjika komanso pang'onopang'ono. Kenako kokerani ma flanges awiriwo ndikusindikiza, ndikuyika ma bolt onse pa flanges (musamangitse pakali pano).
6. Mutatha kutsimikizira malo olondola a flanges awiri, sungani ma bolts sitepe ndi sitepe. Onetsetsani kuti flange imasungidwa mulingo pakukhazikitsa
7. Onani ngati kulimbitsa kwa flange kuli koyenera.
8. Theimeneyi thandizo awiri ndi 3m, PTFE mbale ayenera kuikidwa pakati pa mfundo thandizo ndiakunjachitoliro.
Tsatanetsatane wa Ntchito & Kukonza
1. Othandizira ayenera kudziwa bwinontchitokuyendas pakati pa zipangizo mu dongosolo. Ziyenera kudziwika kuti mpweya wamadzimadzi, nayitrogeni wamadzimadzi ndi argon wamadzimadzi ndi zakumwa za cryogenic. Kutentha kozungulira kukakhala kwakukulu kuposa kuwira, kudzakhala mwachilengedwegasifyndi kupsyinjika, zomwe zimapangitsa kuwonjezeka kwapang'onopang'ono kwa kuthamanga kwa magaziVJP ndi zinazida.
2. Kuzizira kwa VJP musanagwiritse ntchito
Popeza VJP yosagwiritsidwa ntchito ili pamtunda wozungulira, chitolirocho chimadzazidwa ndi mpweya womwe uli ndi chinyezi. Choncho, cholinga cha chisanadze kuzirala ndi: choyamba, kuchepetsa kutentha kwa VJP pang'onopang'ono kutentha kwa madzi a cryogenic, kuti apewe kukhudzana mwachindunji ndi madzi ambiri a cryogenic ndi chitoliro cha kutentha kwachibadwa, kutulutsa mofulumira. ndi kuchuluka kwakukulu kwa gasification, zomwe zimapangitsa kuti VJP ikhale yothamanga kwambiri, motero imayambitsa kuwonongeka kwa VJP ndi zida zamadzimadzi zowonongeka. Chachiwiri, ndikuchotsa pang'onopang'ono mpweya mkati mwa VJP ndikupewa kuchuluka kwamadzimadzi a cryogenic mwachindunji kukhudzana ndi mpweya, zomwe zimapangitsa kuzizira ndi kutsekeka mkati mwa VJP.
Asanayambe kugwiritsanso ntchito vacuum adiabatic chitoliro pambuyo pa ntchito yoyamba kapena kuyimitsa kupanga, kuzizira kudzachitika kuti vacuum adiabatic chitoliro chizigwira ntchito mwachizolowezi pokhapokha chikafika kumalo ogwirira ntchito.
3. ThePrecooling Njirapa VJP

4. Skanyumba PansiVJP
Poyimitsa kulowetsedwa, ndizoletsedwa kutseka ma valve a malekezero onse a VJP nthawi imodzi, kuti apange malo otsekedwa muVJPdongosolo, zomwe zimapangitsa kuti pakhale kupanikizika kwamadzi otsalira mu VJPchifukwa cha gasification.
5. Nthawi ndi nthawiDkuchotsedwa kwaCryogenicLmadzi (LiziOmpweya Wokha)
Chifukwa pali ma hydrocarbons ndi zotsaliraVJP pampweya wamadzimadzi, zinthu izi adzakhala waikamo mu payipi mkati kwa nthawi yaitali pamene ananyamula kudzeraVJP.Ma hydrocarboni akayikidwa mu chubu mochuluka komanso kwa nthawi yayitali, nyengo ikatentha kapenakupanga kwaokosijeni wamadzimadzi ndi stopped, kuchuluka kwa ma hydrocarbon muVJPkumawonjezeka, ndipo zomwe zimachitika ndi mpweya wotsalira zingayambitseankuphulikasion.
6.ChitetezoDevicepa VJP
Mu lililonse laVJPdongosolo liyenera kukhazikitsidwa njira yotulutsira chitetezo (kuphatikizapo valavu yothandizira ndi valavu), Pamene kupanikizika kwa VJP kukufika pakutsegulira kwa ma valve otetezera omwe adzatsegula ndi kumasula nthawi yake. Pa nthawi yomweyo, ampweyama valve amathanso kutsegulidwa pamanja kuti amasule kupanikizika kuti atsimikizire chitetezo cha dongosolo lonse la VJP.
