Endabeni yamantongomane nama-bolts, uma amathuluzi akho engenawo amandla anele, uzoba nobunzima ngezinto ezinzima kakhulu. Uma ubhekene nesimo esinjalo, isikrufu somthelela singaba usizo olukhulu. Kunezinhlobonhlobo zama-wrenches womthelela laphaya, kodwa kungcono kakhulu ukukhetha evumelana nezidingo zakho.
Phakathi kwezinketho ezidume kakhulu, sikhethe izikrufu zomthelela ezimbili ezivame ukusetshenziswa kakhulu, okungama-wrenches angu-3/8 kanye no-½. Kulesi sihloko, sizoqhathanisa isikrufu somthelela esingu-3/8 vs ½ ukuze sikutholele okukufanele.
Kulokhu okuthunyelwe sizomboza:
Iyini i-Impact Wrench?
Ngokuyisisekelo, ama- impact wrenches angu-3/8 kanye no-½ ahlukaniswa ngokobubanzi babashayeli be- impactor bawo. Yize zombili zicishe zifane nokusebenza, awukwazi ukuzisebenzisa endaweni efanayo ngenxa yobukhulu bazo obuhlukene, izakhiwo, amandla, nezinye izici. Nokho, ngaphambi kokudlulela engxenyeni yokuqhathanisa, ake sibe nencazelo emfushane ngaleli thuluzi. Ngoba kuyadingeka ukwazi ukuthi yini i-wrench yomthelela ukuze uqonde ukuqhathanisa kahle.
Isikrufu somthelela simane siyithuluzi lesandla elenza i-torque ngemva kokunikeza umthelela ojikelezayo kungazelelwe. Njengoba ithuluzi lisebenza ngogesi noma lisebenzisa amabhethri athile, udinga umzamo omncane kakhulu ezimweni eziningi futhi ngezinye izikhathi awukho nhlobo umzamo. Futhi, elula umsebenzi wesikrufu somthelela isebenza lapho amandla kagesi eguqulela ngokuqondile kumandla ajikelezayo.
Ngemva kokuthola amandla okuzungeza kungazelelwe ku-shaft yesikrufu sakho somthelela, ungakwazi ukushintshanisa kalula amantongomane namabhawodi. Ingasaphathwa, an umshayeli womthelela yaziwa nangokuthi isibhamu esinamandla, i- impactor, isibhamu esinomoya, isibhamu se-torque, isibhamu somoya, isikrufu somoya, njll.
3/8 vs ½ Ama-Impact Wrenches
Sesikushilo ukuthi lezi zinhlobo ezimbili zama-driver ama- impact ahlukaniswa ngezigaba, zikala ububanzi bomshayeli wazo. Manje, sizoziqhathanisa ngokuhlobene nomunye nomunye.
Usayizi
Okokuqala nokubaluleke kakhulu, umehluko wokuqala phakathi kwalezi zikrini zomthelela ubukhulu bazo. Ngokuvamile, isikrufu somthelela esingu-3/8 sincane kunesikrufu somthelela esingu-½. Njengomphumela walokho, umshayeli womthelela ongu-3/8 ulula futhi uvumela ukuphatha okungcono kunewrench yomthelela engu-½. Nakuba umehluko wesayizi unzima ukuqaphela ngezinye izikhathi, kusobala ukuthi kuyinto enkulu lapho ukhetha phakathi kwabo.
Ukusebenza
Usayizi ohlangene we-3/8 impact wrench usiza ukulingana ezindaweni eziqinile, futhi ungayisebenzisela amantongomane amancane namabhawudi. Ukunemba, ungasusa ama-bolts angu-10 mm noma ngaphansi kalula usebenzisa leli thuluzi. Ngakho-ke, kungaba yithuluzi elihle uma udinga ukunemba nokunemba okwamukelekayo.
Nokho, ungakhetha isikrufu somthelela esingu-½ ukuze uthole amandla aphezulu nokunemba. Empeleni, u-½ onomthelela uwela maphakathi neshadi uma siqhathanisa bonke osayizi bezikrufu zomthelela. Ngakho-ke, ngokuyisisekelo, iza nosayizi owanele womshayeli wokuphatha amantongomane amakhulu namabhawodi, ongeke ukwazi ukuwenza kahle usebenzisa umshayeli womthelela ongu-3/8.
Yize isikrufu somthelela esingu-½ sinamandla engeziwe, awukhathazekile ngokuthola amandla alawulekayo. Ngokuvamile, umshayeli womthelela ongu-½ uqinisekisa ukukhishwa okuphephile kwamantongomane namabhawodi. Nakuba lokhu kungase kube yiqiniso, isikrufu somthelela esingu-3/8 siphinde sisebenze kahle kumabhawodi namantongomane anosayizi omncane.
Power
Akumele siphinde sisho ukuthi isikrufu somthelela esingu-½ sinamandla amakhulu kune-3/8 impact wrench. Ikakhulukazi, i-½ ifanele amaphrojekthi esindayo futhi inikeza itorque ephezulu. Ngale ndlela, uzothola ukuphuma kwengcindezi ephezulu kusuka ku-wrench.
Uma sithatha isikrufu somthelela esivamile esingu-½ ukuze sihlole amandla okukhiphayo, ngokuvamile akhuphukela ku-150 lbs-ft kusukela ku-20 lbs-ft, okuyinani elikhulu lamandla omsebenzi wokuklinya. Ngokusebenzisa amandla anjalo, ungasusa futhi ubhoboze amantongomane futhi uqedele eminye imisebenzi eqinile efanayo usebenzisa lesi sikrufu somthelela.
Ngakolunye uhlangothi, i-3/8 impact wrench iza nokuphuma kwamandla aphansi. Futhi, ayikwazi ukumelana nezimo ezinzima. Usebenzisa lesi sikrini somthelela, ungase uthole amandla afinyelela ku-90 lbs-ft kusuka ku-10 lbs-ft, aphansi kakhulu uma kuqhathaniswa nesikrufu somthelela esingu-½. Ngakho-ke, isikrufu somthelela esingu-½ siyinketho ekhethwayo uma ufuna ukunemba phezu kwamandla.
Sebenzisa
Ake sithi i-3/8 isetshenziswa ezinhlotsheni ezincane kuphela zemisebenzi efana namantongomane, ama-woodworks, ama-DIY, namanye amaphrojekthi afanayo. Idizayini ehlangene yalo mkhiqizo ibhekwa njengelungele imisebenzi elula yokunemba.
Ngokuphambene, ungasebenzisa u-½ emisebenzini yokwakha, ukunakekelwa kwezimboni, imisebenzi yezimoto, imisebenzi yokumiswa, ukukhishwa kwamantongomane, neminye imisebenzi emikhulu efana nalena. Lokhu kusebenza kungenzeka kuphela ngenxa yezinga eliphezulu lamandla netorque. Ngakho-ke, kungcono ukungakhethi isikrufu somthelela esingu-½ uma ungeyena uchwepheshe noma unamathele kunoma yiluphi uhlobo lomsebenzi osindayo.
Design
Ngokucacile, ngeke uthole idizayini efanayo yamamodeli ahlukene anosayizi ofanayo. Ngokufanayo, ama-wrenches angu-3/8 kanye no-½ ayatholakala kumadizayini amaningi namamodeli anikezwa izinkampani ezihlukene. Ngokuvamile, isakhiwo sibukeka njengesibhamu, futhi ungakwazi ukusibamba kalula ukuze usibambe kahle.
Umklamo wokwakha ojwayelekile uhlanganisa isistimu yenkinobho yokuphusha yawo womabili amasayizi. Udinga ukusunduza i-trigger ukuze uqale ukusebenzisa isikrufu somthelela futhi ukhulule i-trigger ukuze usimise. Ngaphandle kwalokho, womabili ama-wrenches womthelela afika namathoshi e-LED nama-display monitors. Kodwa-ke, umehluko omkhulu ekwakhiweni phakathi kwama-wrenches angu-3/8 kanye no-½ amasayizi omshayeli wawo. Yize izinto eziningi zifana kuzo zombili imiklamo ye-wrench, usayizi womshayeli uhlala emkhulu ku-½ wrench yomthelela.
Isiphetho
Ngemva kokwazi zonke izinto ezihlobene, singaphakamisa ukuthi uthole yomibili imikhiqizo uma uchwepheshe. Ngoba, uzokwazi ukusebenza kuzo zombili izimo noma ngabe udinga ukunemba noma amandla. Nokho, uma unesithakazelo ohlangothini olulodwa kuphela, ungakhetha eyodwa.
Ngemisebenzi elula, isikrufu somthelela esingu-3/8 sinikeza ukulawula ukunemba okungcono kakhulu, kuyilapho isikrufu somthelela esingu-1/2 singcono kakhulu ezinhlelweni zokusebenza ezinzima ezidinga amandla aphezulu.
Futhi funda: lezi yizo zonke izinhlobo ze-wrench ezilungisekayo namasayizi ongawadinga
