GB/T 9948-2013 Giredi 1Cr2Mo Mafuta Osweka Mapaipi Mapaipi Azitsulo Opanda Msoko

Kufotokozera Kwachidule:

Chitoliro chophwanyira mafuta ndi chitoliro chachitsulo chosakanizika, chachitali, chozungulira.Kugwiritsiridwa ntchito kwa chitoliro chophwanyika cha petroleum: Amagwiritsidwa ntchito ponyamula mafuta, palafini, mafuta a dizilo ndi zinthu zina zamafuta, zomwe zimatha kukana dzimbiri ndi kuvala.Chitoliro chophwanyira mafuta (gb9948-83) ndi chitoliro chachitsulo choyambirira choyenera pobowola geological ndi kubowola mafakitale.

Chiyambi cha malonda

Kudula kwa petroleum kung'amba chitoliro, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, chitoliro chophwanyidwa chamafuta chimagwiritsidwa ntchito popanga payipi yothamanga kwambiri komanso pamwamba pamitsempha yotentha yotentha yapaipi yapamwamba kwambiri ya carbon structural steel, alloy structural zitsulo ndi zitsulo zosapanga dzimbiri zosagwira kutentha kwambiri. machubu otenthetsera amagwira ntchito pansi pa kutentha kwambiri ndi kupanikizika, chubu chomwe chili ndi mpweya wotentha kwambiri ndi nthunzi wamadzi chimakhalanso ndi okosijeni ndi dzimbiri, chifukwa chake chitoliro chophwanyira mafuta chimayenera kukhala ndi mphamvu zokhalitsa. kukhala ndi mphamvu zopirira kwambiri, kukana kwa okosijeni wambiri, komanso kukhazikika kwadongosolo.

Kuuma kwa chitoliro chophwanyira mafuta kumakhudza kwambiri makina, koma sizinthu zonse zamakina zomwe ziyenera kuuma kwathunthu.Mwachitsanzo, kupindika, mbali za shaft ya torsion, zida zochizira kutentha pamwamba, ndi zina zotero, zimangofunika kuya kwake kowumitsidwa kuti zikwaniritse zofunikira pakugwiritsa ntchito.The quenchability wa petroleum akulimbana chitoliro makamaka anatsimikiza ndi yovuta kuzirala mlingo, ang'onoang'ono kwambiri kuzirala mlingo, bwino quenchability wa mafuta akulimbana chitoliro, ndi mosemphanitsa, m'munsi quenchability wa mafuta akulimbana chitoliro.Kuphatikiza pa Co, zinthu zambiri zowonjezera zimatha kusintha kwambiri kuuma kwachitsulo.

Chiyambi cha Msika

Msika wa chitoliro chophwanyira mafuta mmwamba ndi pansi, masewera aatali ndi afupiafupi ndi aakulu, msika ndi wosakanikirana, zomwe zinapangitsanso kukula kwa kuyembekezera ndikuwona, kufunikira kwa msika kunayimitsidwa.Monga tsiku lomaliza la malonda lisanafike mitengo yamtsogolo ya tchuthi yotsika, ndipo palibe malonda amtsogolo panthawi ya tchuthi, choncho, msika unatsegulidwa pa tsogolo la 10 udakali ndi kupitirizabe kuchepa kunachitika.Ngati tsogolo likhala lotsika, pakapanda uthenga wabwino wowonjezera kuthekera kwa msika wamafuta ophwanyira mafuta kuti atsatire kuchepa kwachulukira, mitengo yamapaipi osweka mafuta akuyembekezeka kuyenda mofooka.
