Ulwazi lwe-thermocouple kunye ne-valve ye-solenoid yokhuseleko yesitovu segesi

Isiphambuka (intloko) ye-thermocouple ibekwe kwilangatye lobushushu obuphezulu, kwaye amandla e-electromotive afumanekayo ayongezwa kwikhoyili yokhuseleko lwe-solenoid valve efakwe kwivelufa yegesi ngokusebenzisa iingcingo ezimbini. Amandla okufunxa aveliswe yiveluva yentsimbi ifunxela isixhobo kwivelufa yentsimbi, ukuze igesi ihambe iye emseleni ngevalufa yegesi.

Ukuba idangatye liyacinywa ngenxa yezizathu zengozi, amandla ombane oveliswa yitrococouple ayanyamalala okanye aphantse anyamalale. Ukutsalwa kwesivingco se-solenoid nako kuyanyamalala okanye buthathaka kakhulu, i-armature iyakhutshwa phantsi kwentshukumo yasentwasahlobo, ibhloko yerabha efakwe entlokweni yayo ibhloko yomngxunya wegesi kwivelufa yegesi, kwaye ivelufa yegesi ivaliwe.

Ngenxa yokuba amandla e-electromotive aveliswa yi-thermocouple buthathaka (zii-millivolts ezimbalwa) kwaye okwangoku kuncinci (kuphela amashumi e-milliamps), ukutsalwa kwekhoyili yovalo yentsimbi yokhuseleko inqongophele. Ke ngoko, ngalo mzuzu wokutshaya, ishafti yevali yegesi kufuneka icinezelwe ukunika amandla angaphandle kwisixhobo ecaleni kwesikhokelo se-axial, ukuze i-armature ikwazi ukufunxwa.

Umgangatho omtsha wesizwe umisela ukuba ixesha lokuvulwa kwevalve ye-solenoid yokhuseleko ≤ 15s, kodwa ilawulwa ngokubanzi ngabavelisi ngaphakathi kwe-3 ~ 5S. Ixesha lokukhutshwa kwevalve ye-solenoid yokhuseleko lingaphakathi kwe-60s ngokwemigangatho yelizwe, kodwa ngokuqhelekileyo ilawulwa ngumenzi phakathi kwe-10 ~ 20s.

Kukwakhona into ebizwa ngokuba "sisiqalo sesibini" isixhobo sokucima umlilo, ikakhulu esisebenzisa i-valve yokhuseleko lwe-solenoid enee-coil ezimbini, kwaye i-coil esandula ukudityaniswa idityanisiwe kwisekethe yokulibaziseka. Ngexesha lokutshaya, isekethe yokulibaziseka ivelisa okwangoku ukugcina i-valve ye-solenoid kwimeko evaliweyo imizuzwana eliqela. Ngale ndlela, nokuba umsebenzisi usikhupha kwangoko isandla sakhe, ilangatye alizukucima. Kwaye zihlala zixhomekeke kwenye ikhoyili kukhuseleko.

Indawo yokufakwa kwe-thermocouple nayo ibaluleke kakhulu, ukuze idangatye libhakwe kakuhle kwintloko ye-thermocouple ngexesha lokutsha. Ngaphandle koko, i-EMF ye-thermoelectric eyenziwe yi-thermocouple ayonelanga, ukufunxwa kwekhoyili yovalo yentsimbi yincinci kakhulu, kwaye izixhobo azinakufunxwa. Umgama phakathi kwentloko ye-thermocouple kunye nesiciko somlilo ngokubanzi yi-3 ~ 4mm.
