Guhitamo imiterere ya kashe yuburyo ni intambwe yingenzi mubikorwa byo gushushanya, igomba kubanza gukora iperereza:
1.Ibipimo byo gukora -Umuvuduko wa Mediya, ubushyuhe, diameter ya shaft n'umuvuduko.
2. Ibiranga urwego ruciriritse - kwibanda, kwijimye, causticity, hamwe cyangwa bidafite ibice bikomeye hamwe n umwanda wa fibre, byaba byoroshye guhumeka cyangwa korohereza.
3. Ibiranga ibikorwa byakiriwe nibidukikije - ibikorwa bikomeza cyangwa rimwe na rimwe; uwakiriye yashyizwe mucyumba cyangwa yerekanwe; Imiterere yikirere ikikije hamwe nubushyuhe bwubushyuhe.
4. Uwakiriye kashe kugirango yemere gusohoka, icyerekezo gisohoka (imbere imbere cyangwa gusohoka hanze) ibisabwa; Ubuzima nibisabwa byiringirwa.
5. Kwakira ku bunini bwimiterere yikimenyetso.
6. Gukora no gutunganya umusaruro uhamye.
Icyambere, ukurikije ibipimo byakazi P, V, T guhitamo:
Hano P nigitutu giciriritse kumurongo wa kashe.Ukurikije ubunini bwagaciro ka P, birashobora kubanza kugenwa niba ugomba guhitamo imiterere iringaniye kimwe nurwego rwo kuringaniza. Kubireba ubukonje buciriritse, amavuta meza, p ≤ 0.8MPa, cyangwa ububobere buke, amavuta mabi yo hagati, p. irashobora gukoreshwa murukurikirane rwikimenyetso-kashe.
U ni umuvuduko uzenguruka wa diametre yikigereranyo cyo hejuru yubuso bwa kashe, kandi ikagena niba ikintu cya elastike kizunguruka hamwe nigitereko ukurikije agaciro k agaciro ka U, kaba gakoresha ubwoko bwimpeshyi buzenguruka cyangwa bwuzuye imitwaro. Muri rusange U munsi ya 20-30m / s irashobora gukoreshwa muburyo bwimpeshyi, guhinduranya umuvuduko mwinshi, bitewe nubwiza butaringanijwe bwibice bizunguruka byoroshye biganisha ku kunyeganyega gukomeye, nibyiza gukoresha imiterere ihagaze neza.Niba agaciro ka P na U byombi birebire, tekereza kumikoreshereze ya hydrodynamic.
T. mubisanzwe byatoranijwe nitrile reberi O-impeta; T hagati ya -50 - + 150 ℃, ukurikije imbaraga zibora zibitangazamakuru, guhitamo reberi ya fluorine, reberi ya silicone cyangwa PTFE ipakira impeta yuzuye irahari.Iyo ubushyuhe buri munsi ya -50 cyangwa hejuru ya 150 ℃, reberi na polytetrafluoroethylene bizatanga ubushyuhe buke cyangwa ubushyuhe bwo hejuru, iki gihe gishobora gukoreshwa ibyuma byerekana ibyuma. ubushyuhe mu murima wa kashe, kandi hagomba gufatwa ingamba zikonje.
Icyiciro cya kabiri, guhitamo ukurikije ibiranga itangazamakuru:
Intege nke zangirika, mubisanzwe ukoreshe kashe yubukanishi, iherezo ryimbaraga za leta hamwe nicyerekezo cyo kumeneka kwitangazamakuru birumvikana cyane ugereranije nubwoko bwo hanze. Kubitangazamakuru bikomeye byangirika, kuko guhitamo ibikoresho byimpeshyi biragoye, urashobora gukoresha hanze cyangwa polytetrafluoroethylene yerekana kashe ya mashini, ariko mubisanzwe ikoreshwa gusa P ≤ 0.2-0.3MPa. bizatera impinduramatwara ntoya yimyenda ihagaritswe.Itangazamakuru ryaka, riturika, rifite uburozi, kugirango harebwe niba itangazamakuru ridatemba, hagomba gukoreshwa inyubako ebyiri-zifite kashe (iziritse).
Ukurikije ibipimo byavuzwe haruguru hamwe nibiranga itangazamakuru biranga imiterere yatoranijwe akenshi ni gahunda ibanza, icyemezo cya nyuma kigomba no kuzirikana ibiranga nyiricyubahiro hamwe nibisabwa bidasanzwe kugirango ushireho kashe.Urugero, uwakiriye mubwato rimwe na rimwe muri gutondekanya kugirango ubone umwanya unoze, ingano yikidodo hamwe n’aho ushyira akenshi usanga bisabwa cyane. Urundi rugero ni ubwato bwamazi kuri pompe yamazi, mumazi yo hejuru no kumanuka, umuvuduko uratandukanye cyane.Muri ibi bihe , imiterere isanzwe ntishobora gutoranywa muburyo busanzwe, ariko igomba kuba yarateguwe muburyo bwihariye bwakazi, kandi igafata ingamba zikenewe
