Lesi isigqoko sokuzivikela esithengiswa emakethe yethu yokuvikela abasebenzi, ngamanani asukela ku-3-15 yuan. Ingabe iyahlangabezana nezidingo zekhwalithi nokusebenza kwezigqoko zokuzivikela? I-GB2811-2019 Izigqoko zokuvikela amakhanda zidinga ukuthi izigqoko zokuzivikela ezivamile zikwazi ukumuncwa umthelela, ukumelana nokubhoboza, nokuhlolwa kwamandla ebhande lesilevini futhi zihlangabezane nezimfuneko.
Usebenzisa isando sokudonsa esingu-5kg, thinta isigqoko sokuzivikela ukusuka kubude obuyimitha elingu-1, futhi amandla adluliselwe esikhunjeni sekhanda akufanele eqe ku-4900N. Akufanele kube khona izingcezu eziwa egobolondweni lesigqoko. Ikhanda lesando liyi-hemispherical, line-radius engu-48mm, eyenziwe ngensimbi engu-45 #, futhi inomumo olinganayo nofanayo. Kungani ingakwazi ukweqa ku-4900N?
I-4900N (i-Newton) iyunithi yamandla, elingana namakhilogremu acishe abe ngu-500 wamandla (kgf).
Ubukhulu bala mandla makhulu impela, futhi uma esetshenziswa ngokuqondile ekhanda lomuntu, angabangela ukulimala okubi kakhulu. Ngokusho kwemiphumela yosesho, izinga lokuklama lezigqoko zokuzivikela zidinga ukuthi akumele zonakaliswe ngaphansi kwamandla omthelela we-4900N ukuvikela ikhanda ekulimaleni.
Lokhu kungenxa yokuthi amandla amakhulu omgogodla womlomo wesibeletho womuntu angama-4900N, futhi ukweqa leli nani lamandla kungase kuholele ekulimaleni komgogodla wesibeletho noma eminye imiphumela emibi. Ngaphandle kokuvikelwa kwesigqoko sokuzivikela, uma amandla angu-4900N esetshenziswa ngokuqondile ekhanda lomuntu, angabangela ukuphuka kogebhezi, ukungqubuzana, noma ukulimala kobuchopho okubi nakakhulu, kubeke ukuphila engozini.
Ngakho-ke, izigqoko zokuzivikela zibaluleke kakhulu izinto zokuzivikela komuntu endaweni yokusebenza, ikakhulukazi ezimweni lapho kunengozi yezinto eziwayo.
Ukuze uqonde kangcono ubukhulu bamandla we-4900N, angafaniswa ngokuguqula amayunithi wamandla. Isibonelo, i-Newton engu-1 cishe ilingana namandla angu-0.102 kilogram.
Ngakho-ke i-4900N ilingana namandla acishe abe ngamakhilogremu angama-500, okulingana namandla adonsela phansi ethani elinguhhafu (500 kilograms) into.
Kafushane, i-4900N ingamandla amakhulu kakhulu okuthi, uma esetshenziswa ngokuqondile ekhanda lomuntu, angabangela ukulimala okubulalayo. Yingakho futhi izigqoko zokuzivikela kufanele zibe nezindinganiso eziqinile zokuqinisekisa ukuthi zingakwazi ukuvikela ukuphepha komuntu ozigqokile uma zibhekene namandla anjalo.
Sebenzisa isando sensimbi esinesisindo esingu-3kg ukuwisa ngokukhululekile futhi ubhoboze isigqoko sokuzivikela sisuka kubude obuyimitha elingu-1. Ikhoni yensimbi akumele ithinte ubuso besikhunta sekhanda, futhi igobolondo le-cap akumele libe nezicucu eziwayo. Isigaxa sensimbi senziwe ngensimbi engu-45 # futhi sinesisindo esingu-3kg. Ingxenye yokubhoboza ine-engeli yekhoni engu-60 °, irediyasi yethiphu yekhoni engu-0.5mm, ubude obungu-40mm, ubukhulu bobubanzi obungu-28mm, nobulukhuni be-HRC45.
Inani lamandla lapho ibhande lesilevu lilimele kumdwebo oguquguqukayo wokumuncwa komthelela nokuhlola ukumelana nokubhoboza kufanele kube phakathi kuka-150N no-250N. Izigqoko zokuzivikela ezikhethekile nazo zidinga izidingo zokusebenza ezikhethekile: ukuqina kwezinhlangothi
Beka isigqoko sokuzivikela ohlangothini phakathi kwamapuleti amabili ayisicaba, nge-brim ngaphandle futhi eduze nepuleti ngangokunokwenzeka: umshini wokuhlola usebenzisa ingcindezi kusigqoko sokuzivikela ngepuleti, futhi ukuguqulwa okuphezulu akufanele kudlule i-40mm, ukuguqulwa okusalayo kufanele. kungabi ngaphezu kuka-15mm, futhi akufanele kube khona izinsalela eziwa egobolondweni lesigqoko.
I-industrial methane flame jet nozzle ifutha ngokuzinzile ilangabi eliluhlaza okwesibhakabhaka ubude obungu-50mm. Ilangabi lisebenza kugobolondo le-cap imizuzwana engu-10 futhi isikhathi sokuthungela akufanele sidlule imizuzwana emi-5. Igobolondo le-cap akufanele lishise.
Ngaphezu kwalokho, kunezidingo zokumelana nezinga lokushisa eliphansi, ukumelana nokushisa okuphezulu ngokwedlulele, ukusebenza kokufakwa kukagesi, ukusebenza kwe-anti-static, nokumelana nokuchaphazwa kwensimbi encibilikisiwe.
