Zosakaniza za DIN 2353 Zimasinthidwa. Cholumikizira Sicho.

Zolemba ziwiri zikugwera pa desiki imodzi. Onsewa amati DIN 2353, mndandanda wopepuka, chubu 12 mm, 315 bar, zinc-nickel. Imodzi ndiyotsika mtengo khumi ndi zisanu ndi zitatu. Wogula amavomereza, nkhani yoyamba imayeza kujambula, ndipo zoyikapo zimapita pamakina omwe amatha miyezi khumi ndi umodzi gulu limodzi lisanayambe kulira. Palibe chimene chinali chifukwa cha kulolerana. Vuto ndi locheperako komanso lovuta kutsutsana nalo: muyezo udauza wogulitsa ulusi ndi 24 degree cone. Sizinawauze kuti mphete yodulira imalowa m'thumba la ndani.

Ndiye yankho lalifupi ndi ili. DIN 2353 zolumikizira zimasinthana pa mawonekedwe komanso kwina kulikonse. Ulusi, ngodya ya cone, chubu kunja kwa m'mimba mwake ndi miyeso yotsatizana imakhazikika, ndichifukwa chake fakitale iliyonse yoyenerera imatha kupanga gawo lomwe limalowera kumapeto kwa chubu lanu. Mgwirizanowu ndi nkhani yosiyana. Mphete yodula, nati yomwe imayendetsa, zitsulo kumbuyo kwake ndi mapepala omwe amatsimikizira maere onse amasiyidwa kwa wogulitsa. Mpata umenewo ndi pamene kupeza kwachiwiri kumalakwika, ndipo oda yogula amatseka kapena kunyalanyaza.

Nkhaniyi ikuyankha mafunso omwe magulu ofufuza amatipatsa, mu dongosolo lomwe amabwera: zomwe chizindikirocho chimatsimikiziradi, ngati mungathe kusunga mtedza ndi mphete zomwe zilipo kale, chifukwa chiyani mawu awiri 'metric bulkhead' sali ofanana, pamene kukakamizidwa kumasiya kufananizidwa, ndi zomwe ziyenera kukhala pa RFQ gwero latsopano lisanakhale lofanana.

Kodi Chizindikiro cha DIN 2353 Chimatsimikizira Chiyani Kwenikweni?

Kuyika chizindikiro pa mbaliyo ndi nkhani ya dimensional, osati kufuna kuchita. Chokwanira chikanyamula DIN 2353 ndi kalata yotsatizana, wogulitsa akukuuzani kuti ikugwirizana ndi zojambula. Ndizo zonse.

Muyezo umakonza mndandanda waufupi. Ndi 24 degree cone angle. Ulusi womwe umaphatikizana ndi chubu chilichonse kunja kwake, kotero 6 mm imatenga M12x1.5, 8 mm imatenga M14x1.5, 10 mm imatenga M16x1.5 ndi 12 mm imatenga M18x1.5 mndandanda wopepuka. Miyeso yotsatizana, yokhala ndi zopepuka zokhala ndi mipiringidzo 315 ndi mndandanda wolemetsa mpaka 630 bar. makulidwe a khoma chubu ayenera kunyamula.

Zimasiya mndandanda wautali wotseguka. Ma geometry a mphete yakeyake, kuphatikiza ngati ili ndi malire amodzi kapena awiri, ndizovuta bwanji komanso momwe kutsogolera kumayendetsedwa. Mbiri yamkati ya mtedza womwe umakankhira mphete patsogolo. Kukhuthala kwa plating mkati mwazololedwa. Gawo lachitsulo, popeza C45 carbon steel ndi 316L zosapanga dzimbiri zonse ndi zosankha zovomerezeka ndipo palibenso chosasinthika. Kaya maerewo adayesedwa umboni kapena kungoyezedwa. Ndi zolemba ziti zomwe zimayenda ndi bokosi.

Werenganinso mndandandawo ndipo mapeto ake ndi ovuta. DIN 2353 imakhala ngati muyezo wapadoko kuposa mulingo wolumikizana. Mafakitole awiri amatha kutsatira izi ndikutumizabe maulalo omwe amachita mosiyana pambuyo pa kukakamiza chikwi.

Kodi Ndingagule Kwa Wopereka Wachiwiri Ndi Kusunga Mtedza Wanga Ndi Ferrules?

Ayi, osati monga chizolowezi. Nati, mphete ndi thupi zimagwira ntchito ngati dongosolo limodzi, ndipo muyezo umangojambula envelopu kuzungulira dongosololo.

Kudula mphete ndi chifukwa. Poyamba, mpheteyo imaluma pamwamba pa chubu ndi mipando yakumbuyo yakumaso motsutsana ndi chubu m'thupi. Imeneyo ndi seti yokhazikika. Tengani cholumikizira padera ndipo mphete yapangidwa kale motsutsana ndi chubu limodzi ndi mpando umodzi. Ikani pa thupi lina ndipo iyenera kuluma kachiwiri. Mphete yomwe yawumitsidwa kamodzi sikudula poyambira, ndipo chisindikizo chomwe mumapeza ndi mwayi osati kupanga.

Mtedza umakhala ndi chifukwa chomwecho kumbali ina. Mtedza ndi chida chomwe chimapanga mphete. Chidutswa chake chamkati chimayendetsa kumbuyo kwa mpheteyo kutsogolo ndi mtunda wokhazikika, ndipo kusiyana kwakung'ono mu mbiriyo kumasintha kutalika kwa mpheteyo komanso komwe kumakhala. Mtedza wochokera ku fakitale imodzi pa mphete kuchokera ku ina ndi magawo awiri a chida chosindikizira chopangidwa ndi zojambula zosiyanasiyana.

Lamulo lofufuza lomwe likutsatira ndi losavuta. Ikani mtedza, mphete ndi thupi pa dongosolo logulira monga chinthu cha mzere umodzi ndi nambala imodzi, osati mizere itatu yomwe imabwera palimodzi. Ngati gwero lachiwiri liyenera kubwera, bweretsani ngati seti yonse ndikuvomerezanso msonkhanowo pa chubu lanu ndi mtengo wanu wa torque. Pali chosiyana chovomerezeka: ngati thupi ndilo gawo lokhalo lomwe mudatha, gwero lachiwiri la thupi lokha ndikusunga mtedza ndi mphete zoyambirira, malinga ngati mpando wa cone umayang'ana pa ngodya ndi kuya.

Mawu Awiri Akuti 'Metric Bulkhead'. Kodi Ndi Gawo Limodzi?

Ayi, ndipo ichi ndiye cholakwika cholozera chomwe timawona nthawi zambiri. Mbali zonse ziwiri zimadutsa mzere kupyola gulu. Zonsezi ndi zopangira bulkhead. Onse ndi metric. Samagwira ntchito yofanana.
