Inzwa yoxinzelelo 296-8060 yeCaterpillar excavator part

Inzwa ye-Thermoelectric

1. Impembelelo ye-Thermoelectric

Xa ii-conductor ezimbini zetsimbi A kunye ne-B ezineempawu ezahlukeneyo ziqhagamshelwe kwiluphu evaliweyo, ukuba amaqondo obushushu okuhlangana awalingani (T0≠T), amandla e-electromotive aya kuveliswa phakathi kwee-conductor ezimbini, kwaye inani elithile langoku liya kubakho iluphu. Le nto ibizwa ngokuba yi-thermoelectric effect.

2. Inzwa yokumelana nobushushu

Izinto zokuxhathisa i-thermal zihlala zintsimbi ezicocekileyo, kwaye iplatinam, ubhedu, i-nickel, isinyithi kunye nokunye zisetyenziswa ngokubanzi.

3. Uluvo lweThermistor

Ii-thermistors zenziwe ngee-semiconductors kwaye zinezi mpawu zilandelayo xa kuthelekiswa ne-thermistors yentsimbi:

1) i-coefficient yeqondo lokushisa elikhulu lokuchasana kunye novelwano oluphezulu;

2) isakhiwo esilula, umthamo omncinci kunye nomlinganiselo wenqaku elilula;

3) Ukumelana okuphezulu kunye nokufanelekileyo kumlinganiselo oguqukayo;

I-4) Ubudlelwane phakathi kokuchasana kunye nokutshintsha kweqondo lokushisa akuhambelani;

5) ukuzinza okubi.

5 ukuhlela okuhleliweyo

Kukho ezintathu ezisetyenziswa ngokuqhelekileyo:

1. Ngokobungakanani bomzimba weenzwa, zinokwahlulwa zibe zinzwa ezifana nokufuduka, amandla, isantya, ubushushu, ukuhamba kunye nokubunjwa kwegesi.

Ngokomgaqo wokusebenza weenzwa, zinokwahlulwa zibe ukuchasana, i-capacitance, i-inductance, i-voltage, iHolo, i-photoelectric, i-grating, i-thermocouple kunye nezinye izinzwa.

2. Ngokobunjani bomqondiso wokuphuma kwenzwa, inokwahlulwa ibe: i-sensor-type sensors ezineziphumo zokutshintsha amaxabiso ("1" kunye "0" okanye "on" kwaye "off"); Imveliso yinzwa ye-analog; Isivamvo seDijithali esisiphumo saso yi-pulse okanye ikhowudi.

I-3.I-Sensors zisetyenziselwa ukulinganisa iqondo lokushisa kunye noxinzelelo lwee-fluid ezahlukeneyo (ezifana neqondo lokushisa, uxinzelelo lwe-airway, ukushisa kwamanzi okupholisa kunye noxinzelelo lwe-fuel injection, njl.); Kukho izinzwa ezisetyenziselwa ukugqiba isantya kunye nendawo yecandelo ngalinye (njengesantya sesithuthi, ukuvulwa kwe-throttle, i-camshaft, i-crankshaft, i-angle kunye nesantya sokuhanjiswa, indawo ye-EGR, njl.); Kukwakho nezinzwa zokulinganisa umthamo we-injini, ukunkqonkqoza, ukungabikho komlilo kunye nomxholo we-oxygen kwigesi yokukhupha; Inzwa yokumisela indawo yokuhlala; Iinzwa zokulinganisa isantya sevili, umahluko wobude bendlela kunye noxinzelelo lwetayara kwinkqubo yokunqanda ukutshixa kunye nesixhobo sokulawula ukunqunyanyiswa; Ukukhusela i-airbag yomkhweli ongaphambili, ayisiyiyo kuphela i-sensor yokungqubana kunye ne-acceleration sensors ezifunekayo. Ukujongana nomthamo wecala lomenzi, i-airbag engaphezulu kunye ne-airbag engaphezulu yentloko egqwesileyo, izinzwa kufuneka zongezwe. Njengoko abaphandi basebenzisa i-anti-collision sensors (i-radar ejikelezayo okanye ezinye izinzwa ezijikelezayo) ukugweba kunye nokulawula ukunyuswa kwe-lateral yemoto, isantya esisheshayo sevili ngalinye kunye ne-torque efunekayo, inkqubo yokuqhawula ibe yinxalenye ebalulekileyo yokulawula ukuzinza kwemoto. inkqubo.
