Intsinga za EPDM: ni ihitamwo ryiza ry'ubushobozi bwinshi-bushobora guhinduka

Mu bikorwa vy'inganda, imodoka, ivy'amazi, n'inguvu nshasha z'ubu, intsinga zikora vyinshi kuruta gusa gutwara ubushobozi-zitegerezwa guhagarara neza iyo ibintu bikomeye, haba ari ubushuhe bukaze, ubukonje, ukunyiganyiga, umunyu, canke uguhora uhinduka. Ivyo vyose bituma .Umugozi wa EPDMsa practical, go-to choice igihe PVC canke ibindi bikoresho bishobora gusaduka, gukomera, canke bikananirwa imbere y’igihe mu bikorwa bisaba nk’ibibanza vya moteri, amawaya y’ubwato, umuyaga/izuba, canke imashini zikomeye. Uyu musi, turaza kuganira ku nyungu nyamukuru z'imirongo ya EPDM n'ibikoresho bibiri vy'ubuhinga bwa UL bikoreshwa mu ruganda rwacu-UL3311 na UL3279.

Inyungu zidasanzwe z'ibikoresho vy'ukwikingira EPDM

EPDM ni igiti c’umupira gikozwe mu bihimba vy’umubiri gifise ikibanza mu bijanye n’ubuhinga bw’intsinga n’imitsi kubera ubushobozi bwaco bwiza cane bwo mu mubiri no mu vy’imiti. Ugereranije n’ibikoresho vya kera vya PVC canke XLPE, EPDM iraruta ayandi yose mu bintu bikurikira:

• Ubushuhe bwinshi: Ishobora gukora neza kuva kuri -50 degrees gushika kuri +90 degrees /105 degrees , kandi ishobora no kwihanganira ubushuhe bwinshi mu bihe bigufi. Ivyo bituma ari vyiza canecane mu gutangura ibikoresho mu turere dukanye mu gihe c’imbeho, canke mu gukoresha amamoteri n’amamashini yo gusudira mu bibanza bifise ubushuhe bwinshi.

• Ishobora guhangana n’ibihe vyiza cane no kurwanya-ugukura: Ishobora guhangana n’imishwarara y’izuba ry’izuba, ozone, n’ugukura kw’ikirere, kandi ntishobora gusaduka canke guhinduka ifu mbere n’igihe kirekire -iri hanze.

• Ishobora guhinduka neza kandi ntishobora gupfukama: Iguma ishobora gukomera mbere n’aho ubushuhe buri hasi, ivyo bikaba bituma ishobora gukoreshwa mu bikorwa bisaba ko umuntu akunda kwinyiganza canke guhungabana, nk’imirongo y’amabateri be n’imirongo y’imirongo y’amarobo y’inganda.

• Ibikorwa vy’umuyagankuba bishikamye: inkomezi nyinshi zo kwikingira n’ubushobozi buke bw’umuyagankuba, bibereye gutanga umuyagankuba w’umuriro uri hagati n’uw’umuriro muto.

• Ibirango: VyinshiUmugozi wa EPDMs zihuye n’ibisabwa na RoHS, kandi umwotsi muto -halogen-utagiramwo ivyuma biriko biragenda biramenyekana buhoro buhoro.

Ego ni ko, EPDM si umuti wo gukiza indwara. Ishobora guhangana n’ibinyabuzima nk’amavuta na peteroli, ni co gituma ibereye cane mu bidukikije bitagira -amavuta canke mu gukorana n’amavuta rimwe na rimwe.

UL3311: Bateri y'uburebure bwa degre 90 n'amamoteri

UL3311ni EPDM izwi cane ifise insulated single-core flexible cable itegeko ry'isoko rya Amerika y'Uburaruko, ahanini ikoreshwa mu gutera amashanyarazi yo mu mutima, gufatanya amabateri, n'imirongo y'amamoteri.

Ivyo bimenyetso birimwo:

• Umurongozi: Igitigiri K canke Igitigiri M gifise umuringa utagira ikintu canke umuringa w'ibiti - (30AWG umugozi mwiza, ushobora guhinduka cane)

• Ivyo kwikingira: Igikoresho co gukingira ubushuhe, akenshi kikaba gifise urupapuro rwo gusohora.

• Inguvu zigereranywa: 600V

• Ubushuhe bugereranywa: -50 degre ~ +90 degre

• Uguhagarika urubeya: Guca mu kigeragezo ca VW-1 canke FT1

• Ibikorwa bisanzwe: intsinga z'amabateri yo mu kiyaga, intsinga zo guhuza ubuhinga bwa UPS, intsinga z'amamoteri y'inganda, intsinga z'amabateri y'imodoka zikoresha umuyagankuba, intsinga z'amashanyarazi y'amamashini aremereye

Akarorero ngirakamaro: Fata umugozi wa 4/0 AWG (ni ukuvuga nk’107 mm2) ugereranijwe munsi ya UL3311-ni ikintu gisanzwe cane ku bijanye n’uguhuza amabarabara y’ibisi mu ma inverter manini canke mu bikoresho vyo kubika inguvu. Ku bushuhe bw’umuyagankuba bwa degre 90, irashobora gukora ata nkomanzi irenga 400A. Intsinzi nyayo ni ingene iguma ihinduka kubera iyo nzira nziza (kenshi 2109 nzira z’urutsinga rwa 30 AWG), kugira ngo ushobore kuyijana mu bibanza bikomeye ata ngorane nyinshi mu gihe co kuyishiramwo.

UL3279: Yavuguruwe 105 degrees Ubushuhe Burengeye Guhitamwo

Niba ibidukikije vyawe vy'ikoreshwa bifise ubushuhe bwinshi canke bisaba igihe kirekire-gukora mu gihe c'ubushuhe bwinshi, UL3279 ni uburyo bwiza bwo gusubiramwo. Igishushanyo caco gisa cane na UL3311 (na co nyene ni umugozi wa EPDM, 600V, umugozi w'umuringa w'umuringa), ariko ubushuhe buraduga bukagera kuri degre 105 .

Ubutandukane nyamukuru:

• Ubushuhe buringaniye: -50 degre ~ +105 degre (ubushuhe bukomeza gukora ni degre 15 zisumbaUL3311)

• Ivyo bishobora gukoreshwa: Ibikorwa bisaba ugushikama kw’ubushuhe bwinshi, nk’ibikoresho vy’inganda biri hafi y’aho ubushuhe buva, amabara y’imashini yo gusudira, n’ugufatanya amabateri y’inguvu nyinshi-mu binyabiziga bimwebimwe bishasha bikoresha inguvu.

• Ubushobozi bwo kwikorera ubu: Munsi y'igice kimwe c'umusaraba-,UL3279ireka umuriro uri hejuru gatoyi ucamwo (kubera urubibi runini rw’ugutera imbere kw’ubushuhe).

Intsinga nyinshi za bateri-nk'izo 2/0 AWG canke 4/0 AWG ubona imisi yose-ziza zifise UL3311 na UL3279 zicapwe neza ku jacket. Ivyo bisobanura mu bikorwa ni uko umugozi ari mwiza gushika ku 90℃iyo uriko urakurikiza amategeko ya UL3311, kandi ushobora gukora gushika ku 105℃iyo uriko uragenda na UL3279. moteri ijana hafi y’ibibanza bishushe (wiyumvire ibice vya moteri, abasudira, canke ibikoresho bihindura ubushuhe) canke ivyo bihuza ubushobozi bwinshi-mu bintu bishasha vy’inguvu nk’amabateri ya EV n’ibikoresho bihindura izuba. Ivyumba vy’umutwe vy’inyongera vy’amadegre 15 biguha gusa amahoro yo mu mutima muri ivyo bibanza bishushe cane kandi biremerera cane.

Igereranyo ry'ibikorwa vy'ivyo bibiri

Impanuro zo kugura no gukoresha

1.Wemeza ubushuhe busabwa: Niba ubushuhe bwo gukoresha igihe kirekire- buri hafi canke burenze degre 90 , UL3279 ni yo ikunda.

2.Itwararike gutera imirongo y’umurongo: Igitigiri ca K (imirongo 30 y’umurongo mwiza) ni co gifise ubushobozi bwo guhindura neza kandi kirabereye gupfukama kenshi.

3.Ibara n’ibimenyetso: Intsinga za bateri zikunda gukoresha umutuku n’umwirabura kugira ngo zitandukanye ivyuma vyiza n’ibibi. Raba nimba umurongo w’inyuma ubereye ama terminals yawe.

4.Icemezo cuzuye: Ibintu vyemewe bikwiye kuba bifise inomero ya dosiye ya UL (E-dosiye), ishobora kugenzurwa kuri internet. Nk'akarorero, uruganda rwacu ni E352430.

5.Ivyiyumviro vyo gushiramwo: NahoUmugozi wa EPDMs zishobora kwambara-, zirinda kwibizwa igihe kirekire mu mavuta; ni vyiza gukoresha ibikoresho bidasanzwe igihe ukuraho amawaya kugira ngo ntuhonye ivyuma bizibira umuriro.

Muri make,Umugozi wa EPDMs zigaragara kubera ubushobozi bwazo bukomeye bwose -hirya no hino mu bihe bikomeye, bikabatuma baja-ku mahitamwo ku bikorwa vyinshi bisaba. high-current connections.Waba uriko urakorana n’ubwato n’ibikoresho vyo mu kiyaga, ivyuma vy’uruganda, ibintu bikomeye vy’inganda, canke imigambi mishasha y’inguvu nk’amabateri n’ama inverter, gutora umugozi wa EPDM ubereye vy’ukuri birafasha ko vyose biguma bikora neza kandi bikamara igihe kirekire.
