Intshayelelo yemitha yokuhamba kobunzima bobushushu

I-Thermal Mass Flow Meter luhlobo lwesixhobo sokulinganisa ukuhamba kwamanzi esisetyenziselwa ukulinganisa isantya sokuhamba kobunzima beegesi. Ngokungafaniyo neemitha zokuhamba zemveli ezilinganisa ukuhamba komthamo, imitha yokuhamba komthamo wobushushu ilinganisa ngokuthe ngqo ukuhamba komthamo wolwelo, nto leyo eyenza ukuba ibe luncedo ngakumbi kwiindawo apho ubushushu kunye nokutshintsha koxinzelelo kunokuchaphazela ukuchaneka kokulinganisa umthamo.

Imitha yokuhamba kobunzima bobushushu isebenza ngokusekelwe kumgaqo wokudluliselwa kobushushu. Isebenzisa inyani yokuba izinga lokudluliselwa kobushushu ukusuka kwi-element eshushu ukuya kwi-gas ejikelezileyo lilingana nezinga lokuhamba kobunzima begesi.

Ingaba isebenza kanjani ?

1. Isiqalelo sokufudumeza:
Isixhobo sokulinganisa ukuhamba kwamanzi sinesixhobo sokuvavanya ukuhamba kwamanzi esifakwe kumjelo wokuhamba kwegesi. Esi sixhobo sihlala sisisixhobo sesinyithi esincinci esifudunyezwa ngombane ukuya kubushushu obaziwayo.

2. Umahluko wobushushu:
Njengoko igesi idlula phezu kwento eshushu, igesi ifunxa ubushushu. Ubushushu be-sensor eshushu buyancipha njengoko ubushushu budluliselwa kwigesi. Ubungakanani botshintsho lobushushu kwi-sensor buxhomekeke kwisantya sokuhamba kobunzima begesi.

3. Ukudluliselwa kobushushu ngokwemilinganiselo yokugeleza:
Okukhona igesi ininzi idlula phezu kwesensor, kokukhona ubushushu obudluliselwayo bukhulu, kwaye ke ngoko, kokukhona ubushushu besensor buya kwehla. Oku kungenxa yokuba iimolekyuli zegesi zisusa ubushushu obuninzi xa zihamba ngokukhawuleza (oko kukuthi, xa isantya sokuhamba kobunzima siphezulu).

4. Umlinganiselo kunye nokubala:
Imitha yokuhamba ilinganisa umahluko wobushushu phakathi kwento eshushu kunye nobushushu obuqhelekileyo (ngokuvamile bulinganiswa ngesenzi sesibini). Ukusuka kulo mahluko wobushushu, imitha yokuhamba ibala isantya sokuhamba kobunzima begesi ngokusekelwe kwii-calibration curves ezichazwe kwangaphambili okanye ii-algorithms.

Izinto eziphambili zeMeter yeThermal Mass Flow:

1. Isixhobo sokuva (iThermistor okanye iRTD):
Le yinxalenye yemitha efudunyezwayo kwaye ubushushu bayo bujongwa ukuze kuchongwe isantya sokuhamba kobunzima.

2. Umthombo wobushushu:
Into encinci yokufudumeza ngombane enika ubushushu kwisenzi.

3. I-Flow Sensor (okanye iProbe):
Iprobe ibekwe kumjelo wegesi kwaye ineenzwa ezilinganisa umahluko wobushushu kunye neemeko zokuhamba.

4. Iprosesa encinci:
Iprosesa ibala isantya sokuhamba kobunzima ngokusekelwe kutshintsho lobushushu olufunyenwe zizinzwa.
