Chifukwa chiyani chitoliro chamafuta othamanga kwambiri chimawonongeka?

(1) Zigawo zamkati ndi zakunja za khoma la payipi yothamanga kwambiri zimapangidwa ndi mphira wosamva mafuta, ndipo pakati ndi (2 mpaka 4 zigawo) za waya wachitsulo woluka kapena waya wachitsulo.Paipi yamtengo wapatali idzawoneka: makulidwe a khoma la payipi ndi losafanana;chingwe cha waya ndi cholimba kwambiri, chotayirira kwambiri kapena chiwerengero cha zigawo zazitsulo ndizochepa;mapindikidwe a payipi (elongation, kufupikitsa kapena kupinda mapindikidwe) pambuyo pressurization ndi lalikulu;wosanjikiza wakunja wa mphira Kusayenda bwino kwa mpweya kumabweretsa dzimbiri kwa waya wachitsulo;Kusasindikiza kosakwanira kwa guluu wamkati kumapangitsa kuti mafuta azitha kulowa muzitsulo zachitsulo;kusamamatika kosakwanira pakati pa guluu wosanjikiza ndi waya waya wosanjikiza.Zomwe zili pamwambazi zidzachepetsa mphamvu yonyamula payipi, ndipo idzaphulika pamalo ofooka a khoma la chitoliro.

(2) Kusankhidwa kosayenera kwa kuchuluka kwa crimping ndi crimping liwiro posonkhanitsa payipi ndi chophatikizira, kapena kusankha kosayenera kwa kapangidwe kake, zakuthupi ndi kukula kwa mgwirizano, kungayambitse payipi ndi mgwirizano kuti apanikizidwe mwamphamvu kwambiri kapena momasuka kwambiri. , zomwe zimapangitsa kuwonongeka koyambirira kwa olowa.Pamsonkhano, ngati kuchuluka kwa crimping kuli kochepa kwambiri, ndiko kuti, pamene kupanikizika pakati pa olowa ndi payipi kumakhala kotayirira, payipiyo imatha kutuluka mumgwirizanowu kumayambiriro kwa kugwiritsidwa ntchito mothandizidwa ndi kukakamiza kwamafuta;Ngati ndizolimba kwambiri, ndizosavuta kuwononga m'dera lamkati la payipi ndi ming'alu., kuchititsa mphira wakunja kuphulika kapena kung'ambika.Pamene payipi ndi chophatikizira zimasonkhanitsidwa, ngati kuthamanga kwa crimping kuli mofulumira kwambiri, n'kosavuta kuwononga mphira wamkati ndi kuphulika kwa waya wosanjikiza wazitsulo, zomwe zidzachititsa kuti payipi iwonongeke msanga isanakwane.Kuonjezera apo, mapangidwe osagwirizana ndi ophatikizana ndi khalidwe losauka bwino lidzawononganso mphira wamkati;ngati zinthu za olowa si bwino anasankha, n'zosavuta deform pa ndondomeko crimping, potero zimakhudza khalidwe crimping ndi kufupikitsa moyo wa payipi.
