Nkibice byingenzi bihuza sisitemu ya hydraulic, ibikorwa byingenzi bihuza hydraulic nibikorwa byingenzi ni ugukwirakwiza neza kandi neza kwanduza amazi ya hydraulic (ubusanzwe amavuta) hagati yimiyoboro nibigize, mugihe ukomeje umuvuduko wa sisitemu no kwirinda kumeneka. Ihame ryimikorere ryabo ririmo ingaruka ziterwa nubukanishi bwamazi, tekinoroji yo gufunga ibikoresho, nuburyo bwubukanishi. Isesengura rikurikira ryibanze ku miterere yimiterere, uburyo bwo gufunga kashe, no gushyira mubikorwa imikorere mubihe bigenda neza.
1. Ibigize Imiterere nuburyo bwibanze bwimikorere
Imiterere shingiro yumuhuza wa hydraulic muri rusange igizwe nibice bitatu: umubiri nyamukuru (igice gihuza), iteraniro rya kashe, hamwe nuburyo bwo gufunga. Umubiri nyamukuru ufite inshingano zo guhuza imirongo ya hydraulic (nkimiyoboro yicyuma na hose) cyangwa ibice bya hydraulic (nka pompe, valve, na silinderi). Igishushanyo cyacyo cyimbere kigomba guhuza diameter nuburyo umuyoboro wamazi. Ikimenyetso cyo gufunga nikintu cyibanze gikora, kandi muburyo busanzwe burimo O - impeta (reberi cyangwa polyurethane), gasketi ikomatanya (ibyuma na rubber), cyangwa hejuru yikimenyetso gikomeye (nkibice bya conical / spherical surface). Uburyo bwo gufunga butuma kandi bukabuza kurekura umuhuza binyuze mumurongo uhujwe (nka NPT na BSPP), ibikoresho byo guhunika (nka SAE J514 compression fitingi), cyangwa byihuse - guhuza inzara (nka - igitutu cyihuta - guhindura imashini zikoreshwa mubikoresho byubwubatsi).
Duhereye ku mikorere, umuhuza hydraulic ugomba icyarimwe kuba wujuje ibyangombwa bitatu byingenzi: icya mbere, shiraho inzira ikomeza amazi kugirango amavuta atambuka; icya kabiri, ihangane numuvuduko wimikorere ya sisitemu (mubisanzwe MPa 10-50, ariko urenga MPa 100 mubihe bikabije) nta guhindura plastike cyangwa guturika; n'icya gatatu, komeza umuvuduko uhamye wa sisitemu uhagarika inzira yimbere ninyuma zinyuze mubice bifunze.
2. Uburyo bwo gufunga kashe: Impirimbanyi zingana zitwarwa nigitutu
Imikorere ya kashe ya hydraulic fitingi niyo ntandaro yimikorere yabo. Ihame ryayo rishingiye ku buryo bubiri bwo "kwikuramo igitutu - gukomera" na "pre - indishyi zo kwikuramo." Iyo hydraulic sisitemu ikora, amazi atanga umuvuduko wambere munsi ya pompe. Kuri iyi ngingo, imbaraga zo guhonyora ku kashe ziyongera uko umuvuduko uzamuka. Kurugero, impeta ya O - irahagarikwa mu buryo bwuzuye, kandi aho ihurira no guhangayikishwa no kwiyongera byiyongera icyarimwe, byuzuza icyuho cya microscopique hagati yumubiri nyamukuru nuhuza (nkibyobo biterwa nuburakari bukabije). Kuri kashe ya conique (nka dogere 74 ya taper ya feri ya hydraulic ya fitingi ya hydraulic), amavuta y igitutu - akora muburyo butandukanye hejuru yubutaka, bigasunika hejuru yikimenyetso hamwe, bigatanga ingaruka nziza zo gutanga ibitekerezo: "uko umuvuduko mwinshi, niko kashe ikomera."
Birakwiye ko tumenya ko gufunga bidashingiye gusa kubintu byoroshye. Mbere - igishushanyo mbonera ni ngombwa. Kurugero, O - impeta isaba igipimo cya 15% - 30% yo kugabanuka mugihe cyo kwishyiriraho (agaciro kihariye katerwa nubukonje bwa reberi nubushyuhe bwo gukora) kugirango ushireho ikimenyetso cyambere nubwo haba hari igitutu gito. Mugihe cyumuvuduko mwinshi -, ibikoresho bigize kashe bigomba kwihanganira gusohora (urugero, fibre - impeta ya polyurethane O - impeta) kandi irwanya ruswa yibitangazamakuru (urugero, fluoroelastomer ikwiranye na fosifate ester hydraulic fluid). Guhagarika pre - bidahagije birashobora gutuma mikorobe - isohoka kumuvuduko muke, mugihe pre-compression ikabije ishobora gutera kwambara cyane hejuru yikimenyetso cyangwa bigatuma guterana no gusenya bigorana.
3. Ihagarikwa ryimikorere munsi ya Dynamic Operating Conditions
Mubikorwa nyabyo, umuhuza wa hydraulic ugomba kwihanganira ihindagurika ryumuvuduko ukabije (nkumuvuduko wigihe gito - umuvuduko ukabije watewe na hydraulic ihungabana), ihinduka ryubushyuhe (bukorera hejuru yubushyuhe bugari bwa dogere 40 kugeza kuri +120 dogere), hamwe no kunyeganyega kwa mashini (nko guhora guhindagurika kwimashini zubaka). Kugira ngo ibyo bibazo bikemuke, ihame ryimikorere ryayo rigera ku mutekano binyuze muburyo bukurikira:
Ubwa mbere, igitutu - igishushanyo mbonera: Ihuza - ihuza ryanyuma akenshi ririmo ibyubaka (nka trottle grooves cyangwa ibyumba bya buffer). Iyo ihungabana rya hydraulic ribaye muri sisitemu, imiterere yo kumanura yongerera igihe umuvuduko wo kuzamuka kandi ikarinda kunanirwa kashe kubera kurenza urugero. Kurugero, bimwe bihanitse - bihuza igitutu cya hose gifite imiyoboro yimbere yimbere yagura inzira ya peteroli kugirango igabanye ingufu zo guhungabana.
Icya kabiri, indishyi zo kwagura ubushyuhe: Imihindagurikire yubushyuhe irashobora gutera itandukaniro mugukwirakwiza ubushyuhe hamwe nuburinganire bwikwirakwizwa ryibikoresho bifunga kashe hamwe nicyuma (urugero, reberi irashobora kwaguka ku gipimo cyikubye inshuro 10 icyuma ku bushyuhe bwo hejuru), ibyo bikaba bishobora guhungabanya kashe yambere yabanjirije kashe. Kugira ngo iki kibazo gikemuke, abahuza bamwe bakoresha imiterere "ireremba ikidodo" (nk'impeta ebyiri O - itondekanya impeta) kugira ngo inteko ya kashe igende mu buryo runaka, yishyure ubushyuhe - bwatewe nimpinduka zingana.
Hanyuma, guhagarika kunyeganyega: Igishushanyo cyo kurwanya - uburyo bwo gufunga uburyo bwo gufunga ni urufunguzo. Kurugero, ingingo zifatanije zikunze guhuzwa nogesheza isoko cyangwa nylon locknuts, zikoresha imbaraga zo guhangana kugirango wirinde kurekurwa guterwa no kunyeganyega. Ku rundi ruhande, ibikoresho byo guhunika, bishingiye ku buryo bwa tekinike ya ferrule mu rukuta rw'imiyoboro (aho kuba imbaraga z'umutwe gusa) kugira ngo ukomeze kwizerwa no mu gihe cyo kunyeganyega igihe kirekire.
Umwanzuro
Ihame ryimikorere ya hydraulic fitingi ni ihuriro ry "kubaka inzira y'amazi," "kuringaniza umuvuduko," no "guhuza n'imihindagurikire y'ikirere." Kuva kashe ihagaze mbere yumuvuduko ukabije - ubushyuhe - guhindagurika kwinshi - guhuza umurima, igishushanyo cyabo kigomba gukurikiza byimazeyo amategeko yubukanishi bwamazi namahame yubumenyi bwa siyansi. Mugihe sisitemu ya hydraulic igenda ihindagurika yerekeza kumuvuduko mwinshi (nka ultra - hejuru - ikoreshwa ryumuvuduko urenga MPa 80) hamwe nubwenge bukomeye (nkibikoresho byubwenge bifite ibyuma bifata ibyuma byifashishwa), amahame yimikorere yibikoresho bya hydraulic bizaza kurushaho guhuza tekinoloji yinganda zikora neza hamwe na logique yo kurwanya imihindagurikire y'ikirere kugira ngo ishobore gukenera inganda zikomeye.
