Lub glow plug tseem hu ua preheating plug.Thaum lub cav diesel txias thaum huab cua txias, lub plug muab cua sov los txhim kho kev pib ua haujlwm.Nyob rau tib lub sijhawm, lub ntsaws hluav taws xob yuav tsum muaj cov yam ntxwv ntawm qhov kub thiab txias ntawm qhov kub thiab txias tsis tu ncua.
Cov yam ntxwv ntawm ntau yam hluav taws xob ntsaws hlau hlau hluav taws xob ntsaws cov yam ntxwv · Ceev preheating lub sij hawm: 3 vib nas this kub tuaj yeem ncav cuag ntau tshaj 850 degrees Celsius · Tom qab cua sov lub sij hawm: Tom qab lub cav pib, lub plug tswj kub (850 ° C) rau 180 vib nas this kom txo tau cov kab mob.· Kev khiav hauj lwm kub: txog 1000 degrees Celsius.Ceramic fais plug nta · Preheating lub sij hawm: qhov kub yuav ncav cuag tshaj 900 degrees Celsius nyob rau hauv 3 vib nas this · Tom qab cua sov lub sij hawm: Tom qab lub cav pib, lub plug tswj kub (900 ° C) rau 600 vib nas this kom txo tau Contaminants.Schematic daim duab ntawm cov qauv hluav taws xob sib txuas · Kev khiav hauj lwm kub: approx.1150 degrees Celsius. Ceev ceev preheating ntawm hlau plug nta · Preheating lub sij hawm: qhov kub yuav ncav cuag ntau tshaj 1000 degrees Celsius nyob rau hauv 3 vib nas this · Tom qab cua sov lub sij hawm: Tom qab lub cav pib, lub plug tswj kub (1000 ° C) rau 180 vib nas this kom txo tau cov kab mob. .· Kev khiav hauj lwm kub: txog 1000 degrees Celsius · PWM teeb liab tswj ceev ceev preheating ceramic plug nta · Preheating lub sij hawm: qhov kub yuav ncav cuag ntau tshaj 1000 degrees Celsius nyob rau hauv 2 vib nas this · Tom qab cua sov lub sij hawm: Tom qab lub cav pib, lub plug tswj kub (1000 ° C) C) rau 600 vib nas this kom txo tau cov kab mob.· Ua haujlwm kub: approx.1150 degrees Celsius · PWM teeb liab tswj Diesel cav pib preheating plugs Muaj ntau ntau hom preheating plugs, feem ntau siv yog peb yam nram qab no: tsis tu ncua;Kev tswj qhov kub thiab txias (nrog rau lub tshuab hluav taws xob preheating rau cov khoom siv ua ntej ua ntej thiab cov khoom siv super preheating tshiab);Tsawg voltage hom rau pa super preheater.Ib tug preheating plug yog screwed rau hauv txhua combustion chamber phab ntsa ntawm lub cav.Lub preheating plug vaj tse muaj preheating plug kuj coil mounted nyob rau hauv ib lub raj.Ib qho hluav taws xob tam sim no dhau los ntawm kev tiv thaiv coil, cua sov lub raj.Lub raj muaj thaj tsam loj thiab tuaj yeem tsim kom muaj cua sov ntau dua.Lub raj yog ntim nrog cov khoom siv insulating los tiv thaiv cov coil tiv thaiv los ntawm kev tiv thaiv sab hauv phab ntsa ntawm lub raj vim kev co.Qhov ntsuas hluav taws xob ntawm ntau yam preheating plugs txawv nyob ntawm seb lub roj teeb hluav taws xob siv (12V lossis 24V) thiab cov khoom siv ua ntej.Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau siv hom preheating plug, kev siv tsis raug preheating plug yuav ua rau ntxov ntxov combustion los yog tsis txaus cua sov.Temperature - tswj preheating plug yog siv nyob rau hauv ntau lub cav diesel.Lub preheating ntsaws yog nruab nrog lub cua sov kauj, uas yog tiag tiag muaj peb kauj - ib tug thaiv kauj, ib tug equalizing kauj thiab ib tug kub hlau kauj - nyob rau hauv series.Thaum cov tam sim no dhau los ntawm lub preheating plug, qhov kub ntawm lub nplhaib kub hlau nyob rau ntawm qhov kawg ntawm lub preheating plug nce, ua rau lub preheating plug incandescent.Raws li qhov kev tiv thaiv ntawm qhov sib npaug ntawm cov coil thiab ntes coil nce siab nrog qhov kub ntawm lub quench coil, qhov tam sim no ntws los ntawm lub quench coil txo.Lub preheating plug yog li tswj nws tus kheej kub.Qee qhov preheating plugs tsis muaj qhov sib npaug ntawm cov coils vim lawv qhov kub thiab txias.Hom tshiab ntawm kev tswj kub preheating plug tsis xav tau lub ntsuas hluav taws xob tam sim no, uas yooj yim rau lub preheating system.[2] Preheating plug monitor type preheating device Preheating plug monitor type preheating device muaj preheating plug, preheating plug monitor, preheating plug relay thiab lwm yam khoom.Thaum lub preheater plug heats li, lub preheater ntsaws saib ntawm lub ntsuas vaj huam sib luag yuav tshwm sim.Lub preheating plug saib yog ntsia rau ntawm qhov ntsuas vaj huam sib luag los saib xyuas cov txheej txheem cua sov ntawm lub preheating plug.Lub preheater plug muaj ib tug resistor txuas nrog tib lub hwj chim mov.Thiab thaum lub preheater plug tig liab, qhov no resistor kuj tig liab (feem ntau, lub preheater plug saib yuav tsum ci liab li 15 mus rau 20 vib nas this tom qab lub Circuit Court yog switched).Ob peb lub preheat plug saib yog txuas nrog nyob rau hauv parallel.Yog li ntawd, yog hais tias lub preheat plug yog luv luv, lub preheat plug saib yuav tig liab ua ntej tshaj li qub.Ntawm qhov tod tes, yog tias lub tshuab hluav taws xob preheater raug txiav tawm, nws yuav siv sij hawm ntev dua rau lub ntsuas hluav taws xob preheater kom tig liab.Lub tshuab hluav taws xob preheater ntsaws rau ntev tshaj li lub sijhawm teev tseg yuav ua rau lub preheater ntsaws saib xyuas.Lub preheat plug relay tiv thaiv ntau dhau tam sim no los ntawm kev pib hloov pauv thiab xyuas kom meej tias lub preheat plug yuav tsis cuam tshuam los ntawm qhov hluav taws xob poob los ntawm lub preheat plug saib. .Lub preheating plug relay yeej muaj ob relays: thaum lub oob khab hloov nyob rau hauv G (preheating) txoj hauj lwm, tam sim no ntawm ib tug relay dhau los ntawm lub preheating plug saib mus rau lub preheating plug;Thaum qhov hloov pauv nyob rau hauv txoj haujlwm START, lwm qhov relay xa ncaj qha mus rau lub preheat plug yam tsis dhau los ntawm preheat plug monitor.Qhov no tiv thaiv qhov hluav taws xob poob vim qhov tsis kam ntawm preheating plug saib thaum pib uas yuav cuam tshuam rau lub preheating plug.
