Uyini Umthetho 1/10 Wokuhoxisa I-Flat Sling?

Umphathi wokukhwabanisa uhlola a isihlilingi esiyisicaba  esisebenze izinyanga ezimbalwa. Amaphethelo awonakele kancane, kanti indawo engaphezulu ikhombisa ukuhuzuka. Indwayimane ibonakala sengathi ibone izinsuku ezingcono—kodwa ingabe isaphephile ukuyisebenzisa?

 

Impendulo ilele kumthetho olula: umthetho we-1/10. Ngokwe-EN 1492-1, indinganiso yaseYurophu yezihlilingi zewebhu ezilukiweyo eziyisicaba, lapho ukugqokwa kwe-abrasive kunciphisa ububanzi bewebhu ngengxenye eyodwa kweshumi noma ngaphezulu kobubanzi bangempela, isihlilingi kufanele sisuswe emsebenzini ngokushesha. I-ASME B30.9 ngokufanayo ibona ukuguga okweqile—ukugqokwa okunciphisa ingxenye enqamulayo yesihlilingi noma okuveza izintambo eziyinhloko—njengesimo esidinga ukuhoxa.

 

I-Lishenflex  isineminyaka engaphezu kwamashumi amabili ikhiqiza izihlilingi eziyisicaba zokwenziwa, futhi idatha yethu yasensimini ibonisa ukuthi ukuhuzuka kungenye yezimbangela ezivame kakhulu zokuyeka umhlalaphansi ngesihlilingi. Nokho ama-rigger amaningi akuthola kunzima ukunquma ukuthi ukuguga 'kweqile' Umthetho we-1/10 unikeza umkhawulo ocacile, olinganisekayo.

 

Uyini Umthetho Ka-1/10?

Umthetho we-1/10 uthi isihlilingi esiyisicaba kufanele sisuswe enkonzweni lapho ukuguga kwehlise ububanzi bewebhu ngo-1/10 noma ngaphezulu kobubanzi bangempela.

 

Empeleni, lokhu kusho:

 

Umthombo: EN 1492-1; I-ASME B30.9

 

Umthetho usebenza ekugqokeni okuhugayo  —hhayi ukusikeka, izinyembezi, noma ezinye izinhlobo zomonakalo. Kodwa-ke, uma umkhawulo ongu-1/10 ufinyelelwa ngenhlanganisela yokuguga kanye nomunye umonakalo, isihlilingi kusafanele siyeke ukusebenza.

 

Kungani Kumiswe Umthetho Ka-1/10?

I-threshold engu-1/10 ayifuni. Ngokusho kwedatha yokuhlola imboni, ukusika onqenqemeni ngo-10% kungehlisa umthamo wesihlilingi ngo-35%. Nakuba umthetho we-1/10 ukhuluma kakhulu ngokuguga (kunokusikeka), isimiso siyefana: uma ububanzi bewebhu sehlisiwe ngo-10%, amandla esihlilingi aba sengozini kakhulu.

 

Izinga le - EN 1492-1  licacisa ukuthi izihlilingi zewebhu ezilukiweyo eziyisicaba kumele zihlolwe ukuthi azikho yini ukuguguleka okulimaza iwebhu kuze kube yilapho ububanzi bangempela buncishiswa. I-ASME B30.9 ngokufanayo idinga ukuthi izihlilingi ezinokuguga okweqile zisuswe kusevisi.

 

Ukuhlolwa ngelebhu ye-Lishenflex kuqinisekisa ukuthi izihlilingi ezinobubanzi obungu-10% obuncishisiwe ngenxa yokuhuzuka zibonisa ukwehla okulinganisekayo kwamandla okuphuka—ngokuvamile ngo-15–25% kuye ngephethini yokuguga. Yingakho umthetho we-1/10 uwumkhawulo wokuphepha obalulekile.

 

Indlela Yokukala Ububanzi Bewebhu

Isilinganiso esinembile sibalulekile ekusebenziseni umthetho we-1/10 ngendlela efanele.

 

Izisetshenziswa ezidingekayo

 

• Itheyiphu yokukala noma irula eneziqu zamamilimitha

• Ama-Caliper ukuze uthole izilinganiso ezinembe kakhudlwana (kunconyelwe amacala omngcele)

• Ingilazi yokukhulisa (kuyakhetheka) ukuze uhlole ukuguga konqenqema

 

Inqubo yokukala

 

1. Khetha ingxenye egqokwa kakhulu yesihlilingi—imvamisa endaweni emaphakathi yobude besihlilingi noma ezindaweni lapho kuxhunywana khona nomthwalo noma i-hardware yokuphakamisa.

 

2. Linganisa ububanzi bangempela—bheka umaka wokuhlonza isihlilingi noma izici zomkhiqizi. Uma ububanzi bangempela bungatholakali, kala ingxenye engagqokile yesihlilingi esifanayo

 

3. Linganisa ububanzi obugugile-endaweni encane kakhulu yendawo egqokiwe

 

4. Bala ukuguga = Ububanzi bangempela − Ububanzi obugugile

 

5. Bala amaphesenti = Gqoka ÷ Ububanzi bangempela × 100%

 

6. Sebenzisa umthetho we-1/10—uma kugqoka ≥ 10% wobubanzi bangempela, buyisela isihlilingi

Amaphuzu Abalulekile

 

• Linganisa ububanzi bonke—hhayi nje endaweni ejulile

• Linganisa ngamaphoyinti amaningi—ukugqoka kungase kungalingani

• Bhala izilinganiso zakho—gcina amarekhodi okuhlola ngokwezidingo ze-ASME B30.9 ngayinye

 

Ukungaqondi Okujwayelekile

Imibono eyiphutha eminingi evamile ingaholela ekusebenziseni okungalungile komthetho we-1/10:

 

Ngokuya nge-ASME B30.9, ukuguguleka okudlulele kuchazwa njengokugqokwa okuveza izintambo eziyinhloko noma okunciphisa ingxenye enqamulayo yesihlilingi. Ngenkathi i-ASME B30.9 ingasho ngokusobala '1/10' ngendlela efanayo I-EN 1492-1  iyakwenza, izinga liyabona ukuthi uma ukugqokwa sekufike endaweni lapho okuphakathi kuvezwe khona noma kuncishisiwe ingxenye ephambanayo, isihlilingi kumele siyeke ukusebenza.

 

I-EN 1492-1, nokho, icacile: ukugqokwa kwe-abrasive kunciphisa ububanzi bewebhu ngo-1/10 noma ngaphezulu kuyisimo sokususwa ngokushesha kusevisi.

Eminye Imibandela Yokuthatha Umhlalaphansi Yama-Flat Slings

Umthetho we-1/10 ungenye yezindlela ezimbalwa zokuthatha umhlalaphansi. Ngokuya nge-ASME B30.9, izihlilingi eziyisicaba kufanele futhi zisuswe uma:

 

• Umazisi ongekho noma ongafundeki

• Ukusha kwe-Acid noma i-caustic

• Ubufakazi bokulimala kokushisa—ukuncibilika, ukusha, noma amabhamuza

• Izimbobo noma izinyembezi eziveza izintambo eziwumgogodla

• Ukuthunga okuphukile noma okugugile ezincekwini ezithwala umthwalo

• Amafindo emzimbeni wendwayimane

• Ukushintsha umbala kanye nezindawo eziphukayo noma eziqinile ezibonisa umonakalo wamakhemikhali noma we-UV/ukukhanya kwelanga

• Izinto ezifakwayo eziboshiwe, ezigqwalile, eziqhekekile, ezigobile, ezisontekile noma eziphukile

 

Ngokwe-EN 1492-1, izihlilingi eziyisicaba kufanele futhi ziyeke ukusebenza uma kukhona umonakalo wokusika ongena kuwebhu noma ukulimala komthungo othinta umthamo wokuthwala umthwalo.

 

Isicelo Esiwusizo

Ukuqinisekisa ukuthi umthetho we-1/10 usetshenziswa ngokungaguquki:

 

1. Qeqesha ithimba lakho—qinisekisa ukuthi bonke abaqaphi nabaphathi bayakwazi ukukala ububanzi bewebhu ngokunembile

 

2. Sebenzisa ama-calipers ukulinganisa okunembile-izinyathelo ze-tape zingase zingalungi ngokuhlukahluka okuncane

 

3. Ukuhlolwa kwamadokhumenti—gcina amarekhodi abonisa ububanzi bangempela nezinsuku zokulinganisa

 

4. Maka izihlilingi ezingabazekayo—bona ngokucacile izihlilingi ezisemngceleni ukuze uzihlolisise

 

5. Phumula ngokushesha—lapho ukuguga kufinyelela ku-10%, susa isihlilingi enkonzweni futhi usibhubhise

 

Izincomo Ezifingqiwe Nezisebenzayo

Umthetho we-1/10 unikeza umkhawulo ocacile, olinganisekayo wokuyeka izihlilingi eziyisicaba ngenxa yokuguga. Uma ububanzi bewebhu sehliswe ngo-10% noma ngaphezulu wobubanzi bangempela, amandla esihlilingi aba sengozini futhi kufanele asuswe enkonzweni.

 

Okuthathwayo okubalulekile:

 

1. Linganisa ububanzi bewebhu ngokunembile—sebenzisa ama-caliper ukuze ulinganise ngokunembile

 

2. Sebenzisa umthetho we-1/10—gqoka ≥ 10% wobubanzi bangempela = ukuthatha umhlalaphansi ngokushesha

 

3. Hlanganisa nezinye izindlela zokuhlola—umthetho we-1/10 ukhuluma ngokuhuzuka, kodwa ezinye izinhlobo zomonakalo nazo zidinga umhlalaphansi

 

4. Imiphumela yokuhlolwa kwedokhumenti—gcina amarekhodi ngokwezidingo ze-ASME B30.9

 

5. Qeqesha iqembu lakho—qinisekisa ukuthi wonke umuntu angasebenzisa umthetho ngendlela efanele

 

I-Lishenflex  ikhiqiza ama-polyester flat slings kumazinga we-EN 1492-1 kanye ne-ASME B30.9, anezimpawu zomthamo ezinemibala ecacile nesiqondiso sokuhlola. Sihlinzeka ngamathuluzi okulinganisa nokuqeqeshwa ukuze sisize ithimba lakho lisebenzise umthetho we-1/10 ngempumelelo.
