Imiba echaphazela ixabiso leSilivere
Isilivere sisinyithi esinqabileyo esikhethekileyo esineempawu ezimbini zempahla kunye nemali.Icala lobonelelo: 1.Imveliso: (1) I-inventri yesilivere: Kukho malunga ne-137,400 yeetoni zesilivere ehlabathini, kwaye isakhula ngesantya esimalunga ne-2% minyaka le.(3) Imigodi yesilivere: ixabiso lesilivere min...Funda ngokugqithisileyo -
SHZHJ, Gxininisa KUQHAGAMSHELWANO NEMALI!
NgoLwesithathu (nge-9 kaNovemba), isilivere ye-LME igcine imeko eguquguqukayo ngaphakathi kosuku lokurhweba.Ivulwe kwi-21.29 yeedola namhlanje, i-21.46 ephezulu ithinte i-$ 21.46 nge-ounce, kwaye iphantsi ithinte i-$ 21.27 nge-ounce.Ngexesha lokushicilela, ixabiso lesilivere labikwa kwi-21.30 yeedola nge-ounce nganye, ukuhla https://www...Funda ngokugqithisileyo -
Ukumiselwa kobukhulu be-rivet, ubude kunye nokuvula
Xa i-rivet, ukuba ububanzi be-rivet bukhulu kakhulu, ukuphazamisa ukwenza kunzima, kulula ukwenza i-sheet metal deformation. Ngokuchasene noko, ukuba ububanzi be-rivet buncinci kakhulu, amandla e-rivet awanelanga, okukhokelela ekwandeni kwe-rivet. inani lee-rivets kunye nokuphazamiseka kwe-c...Funda ngokugqithisileyo -
Iinkcukacha zoqhagamshelwano zesilivere ezihlanganisiweyo
Unxibelelwano lwesilivere oluhlanganisiweyo lubhekisa ngokubanzi kumbane kunye nokuvalwa kombane wombane kunye nokuvala, ukudibana kokwahlula kunye nokucofa, kuba i-terminal conductor yentsimbi ngexesha lokuchukumisa ivelisa ubushushu kwangoko kunye neentlantsi, ikhuthaza indawo yayo yokuchukumisa ...Funda ngokugqithisileyo -
Ukusetyenziswa kweSilver Alloy
Izicelo eziphambili ze-alloys zesilivere zezi: (1) i-solder-based-solder, ngokukodwa isekelwe kwi-alloy-based alloy-based alloy series series, njenge-AgCuZn series, i-AgCuZnCd series, i-AgCuZnNi series;isilivere ye-Nickel alloy, i-alloy yobhedu yesilivere;I-alloy equlethe i-90% yesilivere kunye ne-10% yobhedu ibizwa ngokuba yimali yesiliva ...Funda ngokugqithisileyo -
Ukusebenza koqhagamshelwano lwesilivere kunokuphuculwa af
Ukuze uthintele ukuvutha koqhagamshelwano lwesilivere, i-terminal yoqhagamshelwano olumileyo ibe yimo egobileyo, indawo ephakathi ephumayo.Ngoko i-arc ayiyi kumphezulu woqhagamshelwano wokutsha.Luhlobo lwefomu yoqhagamshelwano olungcono, kwaye ukusetyenziswa kwayo kuyanda.Inkqubo yokusebenza...Funda ngokugqithisileyo -
Amandla agxininiswe kwindawo yoqhagamshelwano kunye nea
Inkqubo yokukhutshwa kwe-arc, ingcambu ye-arc ivelisa inkqubo ye-thermal yomzimba ngenxa yokukhutshwa kwamandla okugxininisekile kwindawo yoqhagamshelwano kunye nomgangatho okufutshane nomphezulu, obangelwa ukunyibilika kunye nokuphuma kwezinto zokudibanisa zesilivere, oku kukukhutshwa kombane okudibanisa isilivere.Kwixesha langoku elincinci kwaye elifutshane ...Funda ngokugqithisileyo -
Ukukhuselwa koqhagamshelwano kunye nemiba yoqhagamshelwano
Siyazi ukuba i-relay yoqhagamshelwano kufuneka ibe nenkohlakalo ngaphezu kwe-Mosfet jikelele, umthwalo we-relay mkhulu kakhulu kune-Mosfet.Umthwalo oqhelekileyo we-DC motor motor, i-DC clutch kunye ne-DC solenoid valves, olu tshintsho lomthwalo wengqondo luvaliwe, amakhulu okanye amawaka eevolthi zamandla ombane ombane obangelwa ...Funda ngokugqithisileyo
