Pipe Wrench, feem ntau siv cov cuab yeej kho vajtse, feem ntau yog cov cuab yeej clamping siv los clamp thiab tig cov kav hlau. Thaum siv, cov yeeb nkab tuaj yeem raug clamped los ntawm lub taub hau ntawm lub pliers, thiab tom qab ntawd tig nrog kev quab yuam kom ua tiav qhov kev sib txuas lossis disassembly. Lub hauv paus ntsiab lus ua haujlwm yog hloov lub zog ntawm lub taub hau ntawm lub taub hau rau hauv kev sib tw torque, uas yog siv rau hauv kev sib tw twisting. Lub zog ntau dua, qhov nruj dua cov yeeb nkab tuaj yeem clamped. Cov yeeb nkab clamps tau siv dav hauv cov kav dej xa hluav taws xob thiab cov kav dej hauv pej xeem kev teeb tsa nrog rau cov roj av thiab kev lag luam mining.
1. Lub cev ntawm cov yeeb nkab ciaj ntswj feem ntau yog nrum los ntawm cov hlau nplaum, uas muaj cov yam ntxwv ntawm lub zog siab thiab zoo toughness. Kuj tseem muaj aluminium alloy pliers. Piv nrog rau cov khoom siv ntawm cov khoom siv hlau, aluminium alloy yog sib dua, tab sis tus nqi kuj yog siab, yog li cov yeeb nkab wrenches ntawm kev ua lag luam tseem yog cov hlau ductile.
2. Lub taub hau ntawm lub taub hau ntawm cov yeeb nkab yog qhov tseem ceeb tshaj plaws uas txiav txim siab nws txoj haujlwm, yog li nws feem ntau yog ua los ntawm cov hlau alloy (xws li chromium-molybdenum steel) thiab tau txais kev kho cua sov kom ua tiav cov hardness txaus, toughness thiab kev pab lub neej ntev.
3. Raws li lawv cov qauv, cov yeeb nkab wrenches feem ntau suav nrog American style, British style, German style, saw hom, thiab lwm yam. Ntawm lawv, American style thiab British style yog cov feem ntau siv. Qhov sib txawv tseem ceeb yog tias txoj haujlwm ntawm cov txiv ntoo kho qhov sib txawv ntawm lub cev clamp. Cov ntsiab lus yog raws li nram no:
Lus Askiv yeeb nkab ciaj ntswj, tseem hu ua liab yeeb nkab ciaj ntswj, muaj ib tug me ntsis slanted taub hau qhib. American yeeb nkab wrench yog me ntsis sib dua, siv tau yooj yim thiab pheej yig. Lub American saw yog hinged mus rau lub clamp kov los ntawm lub coupling phaj, uas yog, ib tug kawg ntawm cov saw yog hinged rau ib kawg ntawm lub coupling phaj, thiab lwm yam kawg ntawm lub coupling phaj yog hinged rau lub clamp kov.
Cov hniav nyob rau pem hauv ntej kawg ntawm lub pliers kov yog faib nyob rau hauv ib tug arc. Thaum cov saw hlau hom yeeb nkab ciaj ntswj ua haujlwm, qhov kawg ntawm cov saw hlau tsis muaj kev sib txuas yog dawb thiab tsis ruaj los yog hinged nrog lub clamp kov. Yeej, tsis muaj qhov sib txawv loj ntawm ob, thiab ob qho tib si British-style yeeb nkab wrenches thiab American-style yeeb nkab wrenches yog heev yooj yim mus use. Feem ntau, lub puab tsaig ntawm cov yeeb nkab ciaj ntswj yog precision forged los ntawm high-quality carbon steel thiab muaj zoo heev toughness. Lub cev clamp yog ua los ntawm cov hlau nplaum, uas tiv thaiv cov khoom clamped los ntawm deforming yooj yim. Qhov tshwj xeeb sab sauv thiab sab hauv lub puab tsaig tsim kom muaj zog clamping nyhuv.
4. Cov yeeb nkab wrench specifications feem ntau muaj npe raws li lawv qhov ntev tag nrho. Cov lus qhia dav dav yog: 8 "(200mm), 10" (250mm), 12" (300mm), 14" (350mm), 18" (450mm), 24 "(600mm), 36" (900mm), 48" (1200mm) ), thiab lwm yam.
5. Cov yeeb nkab wrenches tuaj yeem muab faib ua lub luag haujlwm hnyav, lub luag haujlwm hnyav, lub luag haujlwm hnyav, thiab lwm yam raws li qhov hnyav ntawm lub cev. Feem ntau, cov khoom uas ua los ntawm cov hlau tsis muaj zog yog lub luag haujlwm hnyav, thiab cov uas ua los ntawm aluminium alloy yog lub teeb lub luag haujlwm.
6. Niaj hnub no, raws li cov kev xav tau ntawm cov neeg siv khoom sib txawv, kuj tseem muaj qee qhov tshwj xeeb zoo li cov yeeb nkab wrenches, xws li cov kav dej ntau yam, cov yeeb nkab ceev ceev, supercharged yeeb nkab wrenches, thiab lwm yam.
