Ukuthenga i- i-vacuum umoya we-furnace, kufuneka uqale umisele amandla ayo

Vacuum umoya eziko lobushushu iqondo lobushushu oluzenzekelayo olusetyenziswa imithetho elawulayo elawulayo ibandakanya indawo-ezimbini, indawo-ntathu, isabelo, isabelo esidityanisiweyo kunye nolwahlulo oludityanisiweyo lokwabelana. Ukumelana nolawulo lobushushu bomlilo yinkqubo yokusabela kwimeko. Thelekisa ubushushu bokwenyani beziko kunye neqondo lobushushu lesithando somoya ukuze ufumane impazamo. Emva kokuba impazamo iqhutywe, umqondiso wokulawula ufunyenwe ukulungelelanisa amandla okushisa omlilo wokumelana nomlilo, kwaye emva koko ulawulo lobushushu bomlilo lugqityiwe.

1. Impembelelo yokulawula (ulawulo lwe-PID) iveliswa ngokwesabelo sephutha, ukudibanisa kunye nokwahlula. Yeyona fom yolawulo isetyenziswa kakhulu kulawulo lwenkqubo.

I-2, i-conditioning-position-positioning-ineendawo ezimbini kuphela: i-on and off. Xa ukushisa kwesithando somlilo we-vacuum atmosphere esithandweni singaphantsi kwexabiso elimiselweyo, i-actuator ivulekile ngokupheleleyo; xa ukushisa kwesithando somlilo kuphezulu kunexabiso elimiselweyo, i-actuator ivalwe ngokupheleleyo. I-activator idla ngokuba yi-contactor.

3. Isimo sendawo-ntathu-Inamaxabiso anikiweyo amabini emida ephezulu nasezantsi. Xa iqondo lokushisa lesithando somlilo we-vacuum emoyeni lingaphantsi kwexabiso elinikeziweyo lomda ophantsi, i-contactor ivulekile ngokupheleleyo; xa ukushisa kwesithando somlilo kuphakathi kwexabiso elinikiweyo lomda ophezulu kunye nomda ophantsi, i-contactor ivuliwe ngokupheleleyo. Inxalenye ye-activator ivuliwe; xa iqondo lobushushu lesithando somoya somoya lidlula ixabiso elibekiweyo elibekiweyo, i-actuator ivalwe ngokupheleleyo. Ngokomzekelo, xa i-heater ye-tubular iyinto yokufudumeza, ukulungiswa kweendawo ezintathu kungasetyenziselwa ukugqiba umahluko kumandla okufudumala kunye nokugcina ukushisa.

Ukongeza, xa kuthengwa isithando somlilo se-vacuum, kufuneka uqale unqume amandla ayo. Kwangaxeshanye, kuya kufuneka uqwalasele ukusebenza kakuhle kobushushu bombane kunye namandla ombane. Kukho iindlela ezimbini zokumisela amandla.

Enye yindlela yokulinganisa ukushisa. Ngokomthetho wogcino lwamandla, ubushushu bubonke obusetyenziswa yi-resistance vacuum atmosphere furnace bulingana nobushushu obupheleleyo obukhutshwa yinto yokufudumeza kombane. Ubushushu obupheleleyo obusetyenzisiweyo bubandakanya ukushisa okusebenzayo kokufudumeza isinyithi kunye neelahleko ezahlukeneyo zokushisa kwesithando somoya. Ubushushu obupheleleyo buguqulwa bube namandla apheleleyo, kwaye ukusebenza kakuhle kokufudumala kombane kuthathelwa ingqalelo, kwaye kwandiswe yi-coefficient yokugcina amandla. Lo mlinganiso uqikelela ukuba imveliso yesithando somlilo inokunyuka kwaye ilahleko yobushushu inganyuka. I-coefficient yogcino lwamandla yeyokusebenza ngokuqhubekayo kwesithando somoya, kunye nokusebenza okungapheliyo Olunye uhlobo lwesithando somlilo yindlela yobungqina, eyona nto imisela amandla omlilo ngokomthamo wesithando somlilo.
