Kusintha kwa Zida Zapamwamba za Elastomer mu Kukhazikika kwa Industrial

Malo amakono a mafakitale amatanthauzidwa ndi kufunafuna kosalekeza kwa kulondola ndi mphamvu. Komabe, pakuwonjezeka kwamakina kumabweretsa zovuta zosapeŵeka za kasamalidwe ka mphamvu ya kinetic. M'magalimoto othamanga kwambiri, makina a HVAC, ndi makina a CNC, kusiyana pakati pa machitidwe ochita bwino kwambiri ndi omwe amatha kulephera msanga nthawi zambiri amakhala pamtundu wa zigawo zake zodzipatula. Zipangizo za elastomer zokhala ndi mphamvu zambiri zakhala njira yothetsera vutoli, zomwe zimapereka kusakanikirana kwamphamvu kwa uinjiniya wa ma cell ndi kulimba mtima kwamapangidwe. Poyang'ana kwambiri mapangidwe apamwamba a NBR (Nitrile Butadiene Rubber), mainjiniya tsopano atha kuthetsa kugwedezeka kwa parasitic komwe kunkasokoneza kukhulupirika kwapangidwe komanso kutonthoza kwamawu. 

Kapangidwe ka Mamolekyulu a Rubber Vibration Absorber Components  

Pamtima pa njira iliyonse yochepetsera bwino ndizomwe zimapangidwira polima. Mosiyana ndi mphira wamba wamalonda, ma elastomer apamwamba kwambiri amapangidwa ndi kamangidwe kake komwe kamayika patsogolo kulumikizana kwamphamvu pakati pa maunyolo osinthika. Izi zimatsimikizira kuti zinthuzo zimakhalabe zomveka ngakhale zitakhala zachiwawa, zothamanga kwambiri zomwe zimafanana ndi mafani a mafakitale ndi ma rotor a compressor. Kusankha kwa a mphira kugwedera absorber masiku ano kumaphatikizapo zambiri osati kungosankha chinthu chosinthasintha; pamafunika kumvetsetsa kwakukulu kwa kutentha kwa kusintha kwa galasi ndi katundu wosinthika.

Ma elastomer okhala ndi mphamvu zambiri amapangidwa kuti asunge kutentha kwa galasi lotsika, komwe kumawalola kuti azikhalabe ndi mphamvu zambiri ngakhale m'malo a sub-zero otsika mpaka -40 ° C. Mosiyana ndi zimenezi, kukhazikika kwawo kwa kutentha kumaonetsetsa kuti asafewe kapena kutaya mphamvu yawo yonyamula katundu pa kutentha kufika +120 ° C. Zenera lalitali logwira ntchito ili ndi lofunikira pamakina otumizira ma motor pomwe kuchuluka kwamafuta kumakhala kokhazikika. Pamene mphira umakhala ngati mawonekedwe oyambira pakati pa injini yogwedezeka ndi nyumba yake yolimba, imakhala ngati sinki ya kinetic. Mphamvu zopangidwa ndi injini sizimangotsekeka; imalowetsedwa ndi kutayidwa kudzera m'mikangano yamkati ya maselo mkati mwa elastomer yokha.

Kukhazikitsa Kwadongosolo kwa Vibration Damping Rubber Pads  

Pazinthu zolemetsa monga mayunitsi akunja oziziritsa mpweya kapena makina opumulira mpweya m'mafakitale, kufalikira kwa kugwedezeka kudzera m'munsi mwa zida kungayambitse kuipitsidwa kwaphokoso komanso kutopa kwamapangidwe. Apa ndi pamene kutumizidwa kwa vibration damping pads zimakhala zofunikira. Mapadi amenewa si ma cushion chabe; Ndizigawo zogwira ntchito kwambiri zomwe zimaphatikizana ndi NBR ndi zigawo za aluminiyamu aloyi. Kulumikizana pakati pa choyikapo chitsulo cholimba ndi elastomer yosinthika kumapanga "kulumikizana kosinthika" komwe kumatha kunyamula torque yayikulu ndikupatula gwero la vibration.

Mwachitsanzo, pakuyika kompresa wamkulu, zotsatira zobwera chifukwa cha magawo obwereza kapena kuzungulira ndi zazikulu. Popanda mawonekedwe odziyimira pawokha, zododometsazi zitha kuyenda molunjika ku bulaketi yokwera ndi nyumba yozungulira. Pogwiritsa ntchito ukadaulo wophatikizika wowumba, mapepala onyowawa amapereka yankho losasinthika komanso lodziwikiratu kuzinthu zonse zokhazikika komanso kugwedezeka kwamphamvu. Kapangidwe kamangidwe kameneka kamalepheretsa kuopsa kwa dongosolo la resonance-chodabwitsa pamene kugwedezeka kwa makina kumafanana ndi mafupipafupi a chilengedwe, zomwe nthawi zambiri zimayambitsa kulephera kwa makina.

Kupititsa patsogolo Moyo Wautali Ndi Mayankho Apamwamba Opangira Rubber Damping Pad  

Kukhalitsa ndiye metric yoyamba yomwe zigawo zamakampani zimayesedwa. A mphira wothira mphira ayenera kuchita zambiri kuposa kungoyamwa kunjenjemera; Ayenera kukhala m'malo okhala ndi mafuta opangira mafakitale, mafuta opangira magetsi, ndi mafuta a hydraulic. Ma elastomers opangidwa ndi NBR mwachilengedwe amalimbana ndi ma hydrocarbon-based media, omwe amalepheretsa zinthuzo kutupa kapena kusweka pakapita nthawi. Kukana kwamafuta kumeneku ndikofunikira kwambiri pazida za CNC ndi makina aulimi pomwe kukhudzana ndi mafuta ndi mafuta kumachitika tsiku ndi tsiku.

Kupitirira kukana kwa mankhwala, moyo wa kutopa wa zipangizozi ndi zodabwitsa za kayendetsedwe ka ndondomeko zamakono. Ma elastomer okhala ndi mphamvu zambiri amapangidwa kuti athe kupirira mamiliyoni ozungulira pansi pazambiri zonyamula kwambiri popanda kutaya "rebound" kapena elastic modulus. Kukana kutopa kumeneku kumatheka kudzera pakuphatikizidwa kwa zigawo zapadera zomangira, monga CR (Chloroprene Rubber), zomwe zimatsimikizira kuti mawonekedwe pakati pa mphira ndi zigawo zachitsulo zimakhalabe. Kumangirirako kumachitidwa pogwiritsa ntchito matenthedwe ophatikizika amawumbidwe, gawo lotulukalo ndi gawo limodzi, lolumikizana lomwe limachotsa zofooka zomwe nthawi zambiri zimapezeka muzomangira zamakina kapena zomatira zokha.

Maudindo apadera a Vibration Absorbing Rubber Interface     

Lingaliro la "opareshoni mwakachetechete" mumayendedwe olondola ndi mafani amadalira kwambiri mtundu wa mphira woyamwa vibration mawonekedwe. Phokoso lapamwamba kwambiri ndi kugwedezeka komwe kumayenda mumlengalenga kapena zolimba. Mwa kusandutsa mphamvu ya kinetic iyi kukhala mphamvu yocheperako, elastomer imasokoneza makinawo. Izi ndizofunikira makamaka pamayunitsi owongolera mpweya m'nyumba ndi ma fan othamanga kwambiri, komwe ndikofunikira kuti mukhale ndi mphamvu.

M'machitidwe ozungulira a shaft, ngakhale kusalinganika kowoneka bwino kungayambitse kuvala kwa asymmetric pama bearings ndi zisindikizo. Kuthamanga kwapamwamba kwa kuphatikiza kwa NBR kumapangitsa kuti kusalongosoka pang'ono kulipidwe kokha. "Kudziwongolera" kumeneku kwa ma elastomers othamanga kwambiri kumatsimikizira kuti kufalikira kwa torque kumakhalabe kosalala komanso kosasintha, kumachepetsa "kuwomba" kwanthawi yayitali komwe kumalumikizidwa ndi ma mota olondola. Kuphatikiza apo, pokwaniritsa miyezo yapadziko lonse lapansi yachilengedwe monga RoHS 2.0 ndi REACH, zidazi zimawonetsetsa kuti kufunafuna chete sikumabwera chifukwa cha thanzi lachilengedwe. Ndiwopanda zinthu zovulaza monga PFAS ndi POPs, zomwe zimawapangitsa kukhala oyenera kutumizidwa kunja ndikugwiritsidwa ntchito m'magawo olamulidwa kwambiri.

Malo amakono a mafakitale amatanthauzidwa ndi kufunafuna kosalekeza kwa kulondola ndi mphamvu.
