Plug cemlorot uga disebut plug preheating.Nalika mesin diesel digawe adhem nalika cuaca adhem, plug nyedhiyakake panas kanggo nambah kinerja wiwitan.Ing wektu sing padha, plug listrik kudu nduweni karakteristik kenaikan suhu kanthi cepet lan negara suhu dhuwur sing terus-terusan.
Karakteristik saka macem-macem plug listrik Fitur plug listrik logam · Wektu preheating kacepetan: 3 detik suhu bisa tekan luwih saka 850 derajat Celsius · Post wektu panas: Sawise engine diwiwiti, plug njaga suhu (850 ° C) kanggo 180 detik kanggo ngurangi rereged.· Suhu operasi: kira-kira 1000 derajat Celcius. Fitur plug listrik Keramik · Wektu preheating: suhu bisa tekan luwih saka 900 derajat Celsius ing 3 detik · Post wektu panas: Sawise engine diwiwiti, plug njaga suhu (900 ° C) kanggo 600 detik kanggo ngurangi rereged. Diagram skematis struktur plug listrik umum · Suhu operasi: kira-kira.1150 derajat Celsius. Preheating cepet saka fitur plug logam · Preheating wektu: suhu bisa tekan luwih saka 1000 derajat Celsius ing 3 detik · Post wektu panas: Sawise engine diwiwiti, plug njaga suhu (1000 ° C) kanggo 180 detik kanggo ngurangi rereged .· Suhu operasi: udakara 1000 derajat Celcius·Kontrol sinyal PWM Fitur plug keramik preheating Cepet· Wektu preheating: suhu bisa tekan luwih saka 1000 derajat Celsius ing 2 detik· Wektu dadi panas sawise: Sawise mesin diwiwiti, plug njaga suhu (1000 ° C) kanggo 600 detik kanggo ngurangi rereged.· Suhu operasi: approx.1150 derajat Celsius·Kontrol sinyal PWM Mesin diesel miwiti plug preheating Ana sawetara jinis plug preheating, sing paling akeh digunakake yaiku telung: biasa;Jinis kontrol suhu (kalebu plug preheating kanggo piranti preheating konvensional lan piranti super preheating anyar);Jinis voltase rendah kanggo preheater super konvensional.A plug preheating ngaco menyang saben tembok kamar pangobongan engine.Perumahan plug preheating duwe kumparan resistensi plug preheating sing dipasang ing tabung.Arus listrik liwat kumparan resistance, dadi panas tabung.Tabung kasebut nduweni area permukaan sing gedhe lan bisa ngasilake panas luwih akeh.Tabung kasebut diisi bahan insulasi kanggo nyegah kumparan resistensi kontak karo tembok njero tabung amarga geter.Tegangan dirating saka macem-macem colokan preheating beda-beda gumantung saka voltase baterei digunakake (12V utawa 24V) lan piranti preheating.Mulane, penting kanggo nggunakake jinis plug preheating sing bener, panggunaan plug preheating sing salah bakal dadi pembakaran durung wayahe utawa panas sing ora cukup. Temperatur - plug preheating sing dikontrol digunakake ing akeh mesin diesel.Plug preheating dilengkapi kumparan pemanas, sing sejatine kasusun saka telung kumparan - kumparan blok, kumparan ekualiser lan kumparan kawat panas - ing seri.Nalika saiki liwat plug preheating, suhu ring kabel panas dumunung ing tip saka plug preheating munggah pisanan, nggawe plug incandescent preheating.Minangka resistance saka coil equalizing lan arresting coil mundhak banget karo suhu coil quench, saiki mili liwat coil quench sudo.Plug preheating mangkono ngontrol suhu dhewe.Sawetara plug preheating ora duwe kumparan ekualisasi amarga karakteristik kenaikan suhu.Tipe anyar saka plug preheating kontrol suhu ora perlu sensor saiki, kang simplifies sistem preheating.[2]Piranti preheating jinis monitor plug Preheating piranti preheating jinis plug preheating kasusun saka plug preheating, monitor plug preheating, relay plug preheating lan komponen liyane.Nalika plug preheater dadi panas, monitor plug preheater ing panel instrumen bakal ditampilake. Monitor plug preheating dipasang ing panel instrumen kanggo ngawasi proses pemanasan plug preheating.Plug preheater nduweni resistor sing disambungake menyang sumber daya sing padha.Lan nalika plug preheater dadi abang, resistor iki uga dadi abang (biasane, monitor plug preheater kudu cemlorot abang kanggo bab 15 kanggo 20 detik sawise sirkuit diuripake).Sawetara monitor plug preheat disambungake bebarengan.Mulane, yen plug preheat short-circuited, monitor plug preheat bakal dadi abang sadurungé saka normal.Ing tangan liyane, yen plug preheater pedhot, iku perlu maneh kanggo monitor plug preheater dadi abang.Pemanasan plug preheater luwih suwe tinimbang wektu sing ditemtokake bakal ngrusak monitor plug preheater. Relay plug preheat nyegah arus sing gedhe banget ngliwati switch starter lan mesthekake yen plug preheat ora bakal kena pengaruh voltase sing disebabake dening monitor plug preheat. .Relay plug preheating bener kasusun saka rong relay: nalika switch starter ana ing posisi G (preheating), arus siji relay ngliwati monitor plug preheating menyang plug preheating;Nalika saklar ana ing posisi START, relay liyane ngirim arus langsung menyang plug preheat tanpa ngliwati monitor plug preheat.Iki ngindhari penurunan voltase amarga resistensi monitor plug preheating sajrone wiwitan sing bakal mengaruhi plug preheating.
