Uxhumano ukufakwa kokumqoka kuphela noma ibhethri? Izici kanye nezinzuzo

Ukufakwa kokumqoka kuphela - ithuluzi ukuthi senzelwe wringing, siphendukezela ngezikulufo, dowels nezihluthulelo, ngezikulufo nemishudo. Ngaphezu kwalokho, ingasetshenziswa Drilling ngezinto ezahlukene ngokwemvelo. Futhi screwdriver kuyoba usizo uma bula ukhuni evele.

Inethiwekhi ihlukile ejwayelekile ukufakwa kokumqoka kuphela sokuzivivinya? Ikhono ulungise amandla kokuqina.

Ukufakwa kokumqoka kuphela - iyithuluzi elibalulekile emndenini, kanye ukulungisa izimo. Ngalesi inqubo iyunithi ifenisha inhlangano, ukushintsha sivala umnyango ilula futhi fast. Yiqiniso, uma nje oyikhethile a screwdriver izinga inethiwekhi. Kungenjalo, umsebenzi kuyokulethela imizwelo engakhi kuphela. Thenga Network ukufakwa kokumqoka kuphela ungakwazi ukufinyelela ngisho Internet noma yimuphi omunye esitolo yangempela amathuluzi akhethekile.

Lesi sihloko sizophendula le enethiwekhi isikudilayiva elishajekayo, bayehluka ngesidingo ngonanzelelo kukhethwa yomculo.

Ngaphambi ukuyothenga ukufakwa kokumqoka kuphela, anqume yiphi injongo uzothola ke. Evamile, amathuluzi zingahlukaniswa ngamaqembu amabili: isikudilayiva professional kanye umthengi.

Uma udinga inethiwekhi ukufakwa kokumqoka kuphela nganoma yisiphi elula ikhaya nemisebenzi ezingavamile, yebo, akunandaba mqondo ukukhetha idivayisi zaziziningi izici extra kanye amawijethi. Kuze kube yimanje, efanelekayo ekhaya (amateur) ithuluzi. Nokho, uma uhlela ukufakwa kokumqoka kuphela ukusebenza unomphela, i-professional imodeli singaba usizo kabi, njengoba has a lot of amandla.

Household screwing indlela ifakwe torque engu elilingana 10-15 Nm. Have a professional ukufakwa kokumqoka kuphela torque engu ongafinyelela 130 Nm. Ijubane ukujikeleza 400-500 rev / imiz.

Amathuluzi iimsebenzi professional, ingasetshenziswa hhayi kuphela imisebenzi ejwayelekile emazombezombe / ukusonta, kodwa futhi ngoba evele imishini izakhiwo eziqinile. lokubolekwa ezifana isivinini ukujikeleza ifinyelela 1200-1300 rev / imiz.

Amapayipi noma ukufakwa kokumqoka kuphela ibhethri

Umehluko ezibaluleke kakhulu phakathi kwabo, ngokushesha ukuthi lokhu indlela yokudla. Kuze kube manje, iningi isikudilayiva akhiqizwa emhlabeni wonke izinhlobo elishajekayo. Nokho, isikudilayiva inethiwekhi asikabi babi kakhulu. Isikudilayiva - idivayisi okuyinto amandla yi-amapayipi. Futhi ngenxa izinzuzo okubonakalayo kwesibhakabhaka isidingo esikhulu, amakhasimende amaningi ukujabulela sokuprakthiza ukufakwa kokumqoka kuphela ibhethri. Lokhu inzuzo yikhono ukusebenza kuphi ekhaya. Lokho akusadingeki ukucinga eseduze amandla esidayisa nokwelulwa intambo ukuze umsebenzi.

Amandla ukufakwa kokumqoka kuphela kubuye uhlobo ibhethri ezahlukene, efakwe kuyo. ukuhlukanisa:

- Lithium-Ion (Li-Ion);

- a hydride nickel-metal (Ni-MH);

- nickel-cadmium (Ni-Cd).

Nokho, lithium-ion, ngokusho kongoti, kakhulu eco-friendly. Nokho, lolu hlobo akakubekezeleli okushisa aphansi.

Nickel-metal hydride ibhethri ziyojabula nge umthamo wayo ukusebenzela amacala 500. Nickel-cadmium amabhethri zingamelana amacala 1000. Kule ndaba, amasampula nickel-cadmium ezidumile phakathi abathengi isilinganiso. Kodwa ... cadmium kungaba nemiphumela engemihle emzimbeni womuntu.

Namuhla kukhishwa isikudilayiva, ekwazi ukusekela izinhlobo eziningi amabhethri.
