Amapharamitha edatha abalulekile ama-wrenches kagesi

Amapharamitha edatha abalulekile ezinkini zikagesi afaka i-torque, isivinini sokujikeleza kanye nomthamo webhethri, okubaluleke kakhulu lapho ukhetha isikrufu sikagesi.

1. I-Torque

I-torque iyipharamitha yedatha ebalulekile ye-wrench kagesi, evame ukuvezwa ngamamitha e-Newton (N·m). Kalula nje, i-torque iyi-torque ejikelezayo, ehlobene ngqo namandla okushayela e-wrench kagesi. Uma i-torque inkulu, i-wrench ingasebenza i-torque eningi, okusho ukuthi i-wrench ingaqinisa amabhawodi amakhulu noma ikhulule ama-nuts aqinile. Vele, udinga futhi ukukhetha ububanzi be-torque efanele ngokwezidingo ezithile, ukuze ungalimazi amabhawodi noma ama-nuts ngenxa ye-torque eningi.

2. Isivinini

Ijubane lokujikeleza nalo lingenye yemingcele ebalulekile yedatha yama-wrenches kagesi, avame ukuvezwa ngokujikeleza ngomzuzu (rpm). Uma ijubane lokujikeleza liphezulu, i-wrenches kagesi isebenza kahle kakhulu futhi ingaqedela imisebenzi esheshayo. Kodwa-ke, ijubane lokujikeleza eliphezulu kakhulu lingabangela umonakalo ebholthini noma entongeni, ngakho-ke kuyadingeka futhi ukukhetha ibanga lejubane lokujikeleza elifanele ngokusekelwe ezidingweni ezithile.

3. Umthamo webhethri Umthamo webhethri uyisici esibalulekile esikhathini sokusetshenziswa kwe-wrench kagesi futhi uvame ukuvezwa ngama-ampere-hours (Ah). Umthamo webhethri omkhulu unganikeza isikhathi eside sokusetshenziswa, okusho ukuthi kulula kakhulu ukuwusebenzisa. Vele, udinga futhi ukunaka ibhalansi phakathi komthamo webhethri nesisindo. Umthamo webhethri oweqile ungabangela ukuthi i-wrench kagesi ibe nzima kakhulu futhi ingafaneleki ukusetshenziswa isikhathi eside.

4. Amanye amapharamitha

Ngaphezu kwamapharamitha amathathu angenhla, ama-wren kagesi anezinye izilinganiso, njengesisindo, usayizi, umsindo, njll. La mapharamitha angakhethwa futhi ngokusekelwe ezidingweni ezithile.

Ngamafuphi, i-torque, isivinini sokujikeleza kanye nomthamo webhethri wesipanela sikagesi kuyimingcele ebalulekile yedatha yomkhiqizo futhi kudingeka kukhethwe ngokwezidingo ezithile. Ngesikhathi esifanayo, amanye amapharamitha nawo kudingeka anakwe ukuze ukhethe isipanela sikagesi esifanelana kahle nezidingo zakho.
