Ururimi 
Muburyo bwihuse bwihuse bwinganda zinganda nigishushanyo cya HVAC, imicungire ya resonance ya mashini yavuye mubyifuzo bya kabiri ijya mubikorwa byibanze byubuhanga. Mugihe ibikoresho bigenda birushaho gukomera no guhuzagurika, ingufu zituruka kumuzinduko wihuse hamwe no gusubiranamo bitera ikibazo gikomeye kubunyangamugayo no guceceka mubikorwa. Icy'ingenzi mu gukemura ibyo bibazo ni iterambere ryibikoresho byinshi bya elastomer, cyane cyane bikoreshwa mubikorwa by rubber vibration damping pad kandi kabuhariwe nbr vibration absorber Ibigize. Ibi bikoresho byerekana ihuriro rikomeye rya chimie polymer nubushakashatsi bwububiko, bitanga uburyo bukomeye bwo kwirinda ingaruka mbi zingufu za kinetic.
Fondasiyo ya Molecular ya NBR Vibration Damping Pad
Kumva impamvu an nbr vibration damping pad irenze reberi isanzwe, umuntu agomba kureba imiterere yububiko bwa Nitrile Butadiene Rubber (NBR). Elastomers ifite ingaruka nyinshi zikoreshejwe hakoreshejwe molekulike yitonze, ihuza imiterere, kandi yubatswe. Bitandukanye na reberi rusange, NBR ikoreshwa muriyi padi irangwa nurwego rwo hejuru rwiminyururu yoroheje ifite imikoranire ikomeye. Uyu mwirondoro udasanzwe wimiti ituma ibikoresho bigumana ubushyuhe buke bwikirahure, byemeza ko no mubidukikije bikonje, padi idacika intege cyangwa ngo itakaze ubushobozi bwo gukurura ingufu.
Iyo moteri cyangwa umufana wohereza ingufu muri an nbr vibration damping pad , ibikoresho ntabwo birwanya imbaraga gusa. Ahubwo, ikoresha ubuvanganzo bwimbere kugirango ihindure ingufu za kinetic vibration imbaraga zingirakamaro zingufu zumuriro. Ingaruka ya hystereze niyo isobanura "ingaruka zikomeye" imiterere ya elastomer. Mugukuramo imitwaro yingaruka hamwe numuriro wa dinamike, iyi padi irinda ihererekanyabubasha rituruka ku isoko - nka moteri yihuta ya CNC - kuri chassis cyangwa umusingi ukikije. Iyi mikorere ya molekulari niyo mpamvu ituma NBR ikomeza kuba igikoresho cyatoranijwe kubikoresho bisobanutse bisaba uburinganire bworoshye hagati yo gukomera no gushyigikirwa.
Kuzamura Imiterere ihamye hamwe na Rubber Vibration Damping Pad
Mubikorwa biremereye byinganda zinganda, ibyifuzo byumubiri bishyirwa mubice byo kugabanya ni byinshi. Uwiteka rubber vibration damping pad ikora nkibice byingenzi mubihe nka konderasi yo hanze hamwe ninteko zabafana binganda. Kwishyira hamwe kwinshi-elastique NBR hamwe na aluminium Byoseoy ibice byubatswe hifashishijwe uburyo bwo guhuza amashyuza byahinduye uburyo ibyo bice bikozwe. Ubu buryo bukomatanyirijwe hamwe buteganya ko nta "kunyerera" hagati yikintu cyangiritse nigikoresho cyiyongera, gitanga inzira idafite aho ihuriye no kunyeganyega.
Kubashakashatsi, intego yibanze yo gukoresha a rubber vibration damping pad ni kugabanya sisitemu resonance. Sisitemu ya mashini yose ifite inshuro zisanzwe; niba inshuro ikora ya moteri ihuye niyi frequence karemano, resonance yavuyemo irashobora gukurura kunanirwa kwimiterere. Modulus ihanitse ya NBR ituma iyi padi ikora nka buffer ihindura imikorere ya sisitemu, ikuraho neza inkomoko yinyeganyeza ivuye mubice byoroshye byimashini. Ibi ni ingenzi cyane muri sisitemu yo kohereza abafana / moteri aho uburinganire buringaniye ni itandukaniro riri hagati yimashini imara imyaka icumi nimwe ikananirwa mumezi atandatu.
Gushyira Ingamba za NBR Vibration Absorber muri Sisitemu Zisobanutse
Mugihe udupapuro dutanga ubuso bwagutse bwo gusibanganya ,. nbr vibration absorber ni Byashizweho Kuri Byinshi Byerekanwe Kuri Porogaramu, Nka Gushiraho Imitwe ya HVAC yo mu nzu cyangwa ingingo zogukosora za moteri zifatika. Muri urwo rwego, imikorere ya "absorber" isanzwe. Ntabwo ari icyogajuru gusa; nikintu gikora kigabanya urusaku rwinshi kandi rukumira "hum" ikunze kwibasira inyubako zubucuruzi.
Gukoresha an nbr vibration absorber muri compressor yububiko imyanya yerekana uruhare rwayo mu kwagura ubuzima. Compressor itanga imbaraga zikomeye zo guhubuka mugihe cyo gutangira no kuzimya. Hatariho ingaruka zikomeye za elastomer kugirango zihoshe izo mpanuka, ibimera byimbere hamwe namazu ya compressor byagwa mumunaniro. Mugushira mubikorwa intego yo kunyeganyega, imbaraga zingaruka zikwirakwizwa muri matrise ya elastomer. Byongeye kandi, kubera ko ibyo bice bya NBR birwanya amavuta ya hydraulic, lisansi, hamwe n amavuta yo kwisiga, bikomeza gukora neza ndetse no mubihe bidahwitse byicyumba cya moteri cyangwa hasi muruganda.
Inganda zinganda: NBR hamwe no Kwinjiza Ibyuma
Ihuriro ry’ikoranabuhanga riboneka mu bice aho NBR ihujwe n’inzego zihariye zihuza, nka CR (Chloroprene Rubber), kugira ngo zubahirize amavuta ya aluminium cyangwa SECC (Icyuma, Electrogalvanised, Cold-roll, Ubucuruzi bw’ubucuruzi). Mugihe NBR itanga damping, intoki yicyuma itanga geometrike isabwa kugirango yihuta cyane. Ubu busabane nicyo cyemerera kurema "guhuza byoroshye" bishobora kwanduza umuriro mugihe kimwe cyo guhagarika kunyeganyega.
Mu bikoresho bya CNC na moteri isobanutse, aho gupimwa neza neza muri microne, kunyeganyega gusigara gushobora kwangiza igihangano. Uwiteka nbr vibration damping pad hamwe na moteri ikomatanya yemeza ko umuvuduko wihuse wo gutangira-moteri idasobanura "umuzimu" cyangwa amakosa adahwitse kumutwe. Muguhindura urusaku rwinshi mumbaraga zumuriro no gutanga urubuga ruhamye rwo kuzunguruka, ibisubizo bya elastomer byahindutse intwari zitavuzwe mugihe cyinganda zigezweho.
Mu buryo bwihuse bwihuse bwibikorwa byinganda ninganda za HVAC, imicungire ya resonance ya mashini yavuye mubibazo bya kabiri ijya mubikorwa byibanze byubuhanga.
