Kodi 7: 1 Chitetezo Ndi Chiyani Ndipo Chifukwa Chiyani Ili Yofunika?

Woyang'anira zowerengera amasankha a gulaye yonyamula  idavotera matani 2. Katunduyo amalemera matani 1.5—kupitirira malire. Koma chimachitika ndi chiyani ngati gulaye yadzaza ndi mantha? Bwanji ngati katunduyo akuganiziridwa molakwika? Bwanji ngati kuwonongeka kwa chilengedwe kwafooketsa ulusi? Choponyera chokhala ndi chitetezo cha 7: 1 chimapereka chitetezo chofunikira pazochitika zosayembekezereka izi.

 

Lishenflex  yakhala ikupanga zonyamula zonyamula kwazaka zopitilira makumi awiri, ndipo funso limodzi lomwe timamva pafupipafupi kuchokera kwa ogwiritsa ntchito ndi: Kodi nambala ya 7: 1 pa tag ikutanthauza chiyani? Yankho lake ndilofunika kwambiri pazitsulo zotetezeka - ndipo nthawi zambiri sizimveka bwino.

 

Safety Factor vs. Working Load Limit: Kumvetsetsa Kusiyanako

Kuti mumvetse chitetezo cha 7: 1, choyamba muyenera kusiyanitsa pakati pa mawu awiri ofunika kwambiri: Kugwira Ntchito Zowonongeka (WLL) ndi Kuphwanya Mphamvu  (yomwe imatchedwanso Minimum Breaking Load kapena MBL) .

 

Malingana ndi Hercules Lifting guide , mgwirizano pakati pa zikhalidwe ziwirizi umatsimikiziridwa ndi kapangidwe kake: WLL = Breaking Strength ÷ Design Factor .

 

cha 7:1 Chitetezo  chimatanthawuza kuthyoka kwa gulaye kuwirikiza kasanu ndi kawiri WLL yake. Kwa 1-tani WLL gulaye, mphamvu yosweka ndi matani 7 osachepera. Monga tafotokozera mu miyezo yamakampani kuphatikiza TS EN 1492-1 ndi EN 1492-2 EN 1492-2 , chiŵerengerochi ndichofunikira kwambiri pazitsulo zopangira.

Chifukwa chiyani 7:1 ya Synthetic Lifting Slings?

Mitundu yosiyanasiyana ya zida imagwiritsa ntchito zinthu zosiyanasiyana zotetezera:

 

Zida zopangira ulusi zimafunikira chitetezo chokwera kuposa chingwe cha waya kapena unyolo chifukwa zimakhala pachiwopsezo cha zinthu zachilengedwe zomwe zimatha kutsitsa mphamvu popanda chenjezo lowonekera.

 

Malinga ndi WorkSafe WA's Mines Safety Bulletin No. 155 , zoponyera zozungulira zopangira zimakhala zovuta kwambiri kuwonongeka kwa thupi, kuwala kwa dzuwa (ultraviolet), mankhwala, ndi kutentha kwakukulu kuposa mitundu ina ya zida zonyamulira. Chinthu cha 7: 1 chimapereka chitetezo motsutsana ndi zochitika zenizeni zapadziko lapansi izi.

 

Monga Lifting Gear Direct  amalembera mu malangizo awo a mankhwala, kusintha kwaposachedwapa kwa mafakitale kumafuna kuti mitundu ina ya zitsulo zonyamulira zikhale ndi 7: 1 chitetezo m'malo mwa chiŵerengero chakale cha 5: 1-kutanthauza kuti slings tsopano ali ndi katundu wochepa wosweka kasanu ndi kawiri WLL yawo.

 

Mtengo Weniweni Wapadziko Lonse wa 7:1 Chitetezo Factor

Chinthu cha 7: 1 sichimangokhala. Zimawerengera:

 

Kutsitsa kwadzidzidzi - kutumiza kapena kutulutsa mwadzidzidzi

 

Kusuntha kwamphamvu - kugwedezeka kapena kusuntha panthawi yokweza

 

Kuwonongeka kwa chilengedwe - UV, mankhwala, kapena kuwonongeka kwa kutentha pakapita nthawi

 

Kuwonongeka ndi kung'ambika - zilonda, mabala, ndi kuwonongeka m'mphepete

 

Zochita za ngodya -kuchepetsa mphamvu pakutsamwitsa kapena kugunda kwa dengu

 

Kulekerera kwa kupanga - kusiyanasiyana kwazinthu ndi zomangamanga

 

Malinga ndi CERTEX Denmark , nsalu zopangira nsalu zimakhala pachiwopsezo chachikulu chakuthwa m'mphepete, kuvala ndi kukangana, kudula ndi misozi, kutentha kopitilira malire ovomerezeka, mankhwala osagwirizana, komanso kuwonekera kwa UV pakapita nthawi. Chitetezo cha 7: 1 chimapereka malire pazowopsa izi, kuwonetsetsa kuti gulaye yomwe yawonongeka chifukwa cha kuwonongeka kwa chilengedwe ingakhalebe ndi mphamvu zotsalira zokwanira kuti zithe kunyamula katundu wake motetezeka.

 

Kuyesa kwa labu la Lishenflex kumatsimikizira kuti ngakhale kudulidwa kwa 10% - komwe kungathe kuphonya poyang'ana mwamsanga musanagwiritse ntchito - kungachepetse mphamvu ya gulaye ndi 35%. Chinthu cha 7: 1 chimatsimikizira kuti gulaye yokhala ndi zowonongeka pang'ono ikhoza kukhalabe ndi mphamvu zokwanira kukweza katundu wake. Ichi ndichifukwa chake chitetezo chapamwamba sikungofunika kutsatiridwa-ndichofunikira kwenikweni.

 

Momwe 7:1 Chitetezo Chimawonekera Pochita

Pansi pa EN 1492-1 ndi EN 1492-2, chitetezo cha 7: 1 chimaphatikizidwa ndi zolembera zamitundu:

 

Gwero: EN 1492-1/2 Miyezo yamitundu yamitundu

 

DIN EN 1492-2  imanena kuti gulaye zozungulira ziyenera kukhala ndi chitetezo chokwanira cha 7: 1, kutanthauza kuti WLL ya 1000 kg imagwirizana ndi katundu wopuma wa 7000 kg. Mafotokozedwe a malonda a SpanSet amatsimikizira kuti masing'ong'ong'ana awo amapangidwa ndi chitetezo cha 7: 1, ndipo chinthu chilichonse chimaperekedwa ndi satifiketi yofananira ndi nambala yapadera yotsatiridwa.

 

Miyezo Yomwe Ikulamulira 7:1

Chitetezo cha 7: 1 chimalamulidwa ndi miyezo ingapo yapadziko lonse lapansi yopangira zida zopangira:

 

WorkSafe WA  imatsimikizira kuti ma slings ozungulira a polyester omwe amagwirizana ndi AS 4497: 2018, katundu wocheperako wosweka ndi kasanu ndi kawiri WLL yawo , ndipo payekhapayekha amapakidwa umboni kuwirikiza kawiri WLL yawo.

 

Mwachidule ndi Malangizo Othandiza

cha 7: 1 Chitetezo  ndi gawo lofunikira kwambiri lomwe limapereka malire pakati pa kusweka kwa gulaye ndi malire ake ogwirira ntchito. Izi ndizomwe zimayambitsa zochitika zenizeni padziko lapansi, kuwonongeka kwa chilengedwe, kuwonongeka kwa chilengedwe, mavalidwe, ndi zinthu zomwe zimatha kusokoneza mphamvu ya gulaye.

 

Zofunikira zazikulu:

 

1.7:1 idalamulidwa ndi EN 1492-1/2 ndi AS 4497:2018  pazitsulo zopangira

 

2.WLL sikuthyola mphamvu - musagwiritse ntchito mphamvu zosweka ngati malire

 

3.Chitetezo chapamwamba cha zopangira ndi chifukwa cha kusatetezeka kwawo  ku UV, kutentha, mankhwala, ndi kuwonongeka kwa thupi.

 

4.Nthawi zonse yang'anani chizindikiro cha gulaye -chimawonetsa zonse ziwiri za WLL ndi chitetezo

 

5.Yendetsani pafupipafupi —chinthu cha 7:1 ndichotchingira, osati choloweza m’malo mwa kukonza bwino

 

Lishenflex  imapanga ma slings onyamula okhala ndi 7: 1 chitetezo factor, mogwirizana ndi EN 1492-1 ndi EN 1492-2 miyezo. Zogulitsa zathu zimakhala ndi zizindikiritso zamitundu yowoneka bwino, manambala apadera kuti azitha kufufuza, ndipo zimapakidwa umboni kuti zitsimikizire kudalirika.

 

Ngati mukufuna kuthandizidwa kuti mumvetsetse zofunikira zachitetezo pamachitidwe anu onyamulira—kapena ngati mukufuna thandizo lotsimikizira kuti gulaye zanu zikukwaniritsa zofunika—chonde tumizani imelo kwa sales@lishenflex.com , ndipo gulu lathu laukadaulo lidzapereka chithandizo chamunthu payekha.
