Pankhani ya mtedza ndi ma bolts, ngati zida zanu zilibe mphamvu zokwanira, mudzakhala ndi vuto ndi zinthu zolemera kwambiri. Ngati mukukumana ndi izi, chowongolera chowongolera chingakhale chothandizira kwambiri. Pali mitundu yosiyanasiyana ya ma wrenches kunja uko, koma ndi bwino kusankha yomwe ikugwirizana ndi zosowa zanu.
Mwa zisankho zodziwika bwino, tasankha ma wrench awiri omwe amagwiritsidwa ntchito kwambiri, omwe ndi ma wrenches 3/8 ndi ½. M'nkhaniyi, tifanizira wrench ya 3/8 vs ½ kuti tikudziweni bwino.
Mu positi iyi tikambirana:
Kodi Wrench Impact ndi Chiyani?
Kwenikweni, ma wrenches 3/8 ndi ½ amagawidwa molingana ndi kukula kwa ma driver awo. Ngakhale onse ali ndi magwiridwe antchito ofanana, simungathe kuzigwiritsa ntchito m'munda womwewo chifukwa cha kukula kwake, mawonekedwe, mphamvu, ndi zina. Komabe, tisanapite ku gawo lofananitsa, tiyeni tifotokoze mwachidule za chida ichi. Chifukwa ndi kofunikira kudziwa chomwe chimakhudza wrench kuti mumvetsetse kufananitsa bwino.
Wrench yamphamvu ndi chida chamanja chomwe chimapanga torque pambuyo potembenuza mwadzidzidzi. Pamene chida chimayendera magetsi kapena chimagwiritsa ntchito mabatire enieni, mumafunika khama lochepa kwambiri nthawi zambiri ndipo nthawi zina palibe kuyesetsa konse. Ndipo, zosavuta ntchito ya wrench yamphamvu amagwira ntchito pamene mphamvu yamagetsi imasintha mwachindunji kukhala mphamvu yozungulira.
Mutalandira mphamvu yozungulira mwadzidzidzi pamtunda wa wrench yanu, mutha kutembenuza mtedza ndi ma bolt anu mosavuta. Osanenapo, a zotsatira dalaivala amadziwikanso ngati mfuti yamphamvu, impact, mfuti yamphepo, torque gun, air gun, air impact wrench, etc.
3/8 vs ½ Impact Wrenches
Tanena kale kuti mitundu iwiriyi ya madalaivala amagawika m'magulu, kuyeza kuchuluka kwa madalaivala awo. Tsopano, tiwafanizitsa iwo achibale kwa wina ndi mzake.
kukula
Choyamba, kusiyana koyamba pakati pa ma wrench okhudzidwa ndi kukula kwawo. Nthawi zambiri, wrench ya 3/8 imakhala yaying'ono kuposa ½ wrench yamphamvu. Zotsatira zake, choyendetsa cha 3/8 chimakhala chopepuka ndipo chimalola kugwirira bwino kuposa ½ wrench. Ngakhale kusiyana kwa kukula kumakhala kovuta kuzindikira nthawi zina, mwachiwonekere ndi chinthu chachikulu posankha pakati pawo.
magwiridwe
Kukula kophatikizika kwa wrench ya 3/8 kumathandizira kulowa m'malo olimba, ndipo mutha kuyigwiritsa ntchito ngati mtedza ndi ma bolt ang'onoang'ono. Kunena zowona, mutha kuchotsa mabawuti 10 mm kapena ocheperako mosavutikira pogwiritsa ntchito chida ichi. Chifukwa chake, ikhoza kukhala chida chachikulu mukafuna kulondola kovomerezeka komanso kulondola.
Komabe, mutha kusankha ½ wrench yamphamvu kwambiri komanso yolondola. Kwenikweni, ½ impactor imagwera pakati pa tchati tikayerekeza makulidwe onse a ma wrenches. Chifukwa chake, kwenikweni, imabwera ndi kukula kokwanira koyendetsa kuti mugwire mtedza ndi ma bolts akulu, zomwe simungathe kuchita bwino pogwiritsa ntchito dalaivala wa 3/8.
Ngakhale wrench ya ½ ili ndi mphamvu zambiri, mulibe nkhawa kuti mupeze mphamvu yowongolera. Nthawi zambiri, woyendetsa wa ½ amatsimikizira kuchotsedwa kwa mtedza ndi mabawuti. Ngakhale izi zitha kukhala zoona, wrench ya 3/8 imagwiranso ntchito bwino pamaboti ang'onoang'ono ndi mtedza.
mphamvu
Sitiyenera kunenanso kuti wrench ya ½ ndi yamphamvu kuposa 3/8 impact wrench. Nthawi zambiri, ½ ndiyoyenera ntchito zolemetsa ndipo imapereka torque yayikulu. Mwanjira iyi, mupeza kutulutsa kwamphamvu kwambiri kuchokera pa wrench.
Ngati titenga wrench ya ½ yokhazikika kuti tiyese mphamvu yotulutsa, nthawi zambiri imakwera mpaka 150 lbs-ft kuyambira 20 lbs-ft, yomwe ndi mphamvu yochulukirapo pantchito zowononga. Pogwiritsa ntchito mphamvu zotere, mutha kuchotsa ndi kubowola mtedza komanso kumaliza ntchito zina zolimba zofananira pogwiritsa ntchito wrench yamphamvu iyi.
Kumbali ina, 3/8 impact wrench imabwera ndi mphamvu zochepa. Ndipo, sichingathe kupirira mikhalidwe yolemetsa. Pogwiritsa ntchito wrench yamphamvu iyi, mutha kukwera mpaka 90 lbs-ft mphamvu kuyambira 10 lbs-ft, yomwe ndi yotsika kwambiri poyerekeza ndi wrench ya ½. Chifukwa chake, wrench ya ½ ndi njira yabwino mukafuna kuwongolera mphamvu.
ntchito
Tinene kuti 3/8 ingagwiritsidwe ntchito m'njira zing'onozing'ono monga mtedza wa zip, matabwa, ma DIY, ndi ntchito zina zofananira. Mapangidwe ophatikizika a mankhwalawa amawonedwa ngati abwino kwa ntchito zosavuta zolondola.
M'malo mwake, mutha kugwiritsa ntchito ½ imodzi pantchito zomanga, kukonza mafakitale, ntchito zamagalimoto, kuyimitsa, kuchotsa mtedza, ndi ntchito zina zazikulu ngati izi. Kuchita uku kumatheka chifukwa cha kuchuluka kwake kwa mphamvu ndi torque. Chifukwa chake, ndibwino kuti musasankhe wrench ya ½ pomwe simuli katswiri kapena wokhazikika pamtundu uliwonse wantchito yolemetsa.
Design
Mwachindunji, simungapeze mapangidwe ofanana amitundu yofanana. Momwemonso, ma wrench a 3/8 ndi ½ amapezeka mumapangidwe ambiri ndi mitundu yomwe imaperekedwa ndi makampani osiyanasiyana. Kawirikawiri, mawonekedwewo amawoneka ngati mfuti, ndipo mukhoza kuigwira mosavuta kuti mugwire bwino.
Mapangidwe amtundu wanji amaphatikizapo kankha-batani kachitidwe kamitundu yonse. Muyenera kukankhira choyambitsa kuti muyambe kuyendetsa wrench ndikumasula choyambitsa kuti muyimitse. Kuphatikiza apo, ma wrench onse amadza ndi nyali za LED ndi zowunikira. Komabe, kusiyana kwakukulu pamapangidwe pakati pa ma wrench 3/8 ndi ½ ndi makulidwe awo oyendetsa. Ngakhale zinthu zambiri zimakhala zofanana pamapangidwe onse a wrench, kukula kwa dalaivala kumakhala kokulirapo nthawi zonse mu wrench ya ½.
Kutsiliza
Titadziwa zonse zokhudzana, titha kukuwuzani kuti mutenge zonse ziwiri ngati ndinu akatswiri. Chifukwa, mudzatha kugwira ntchito zonse ziwiri ngati mukufuna kulondola kapena mphamvu. Komabe, ngati mumangokonda mbali imodzi, ndiye kuti mutha kusankha imodzi.
Kwa ntchito zosavuta, wrench ya 3/8 imapereka chiwongolero chabwino kwambiri, pamene 1/2 wrench yamphamvu ndi yabwino kwambiri pa ntchito zolemetsa zomwe zimafuna mphamvu zambiri.
Werenganinso: awa ndi mitundu yonse yosinthika yama wrench ndi makulidwe omwe mungafune
