ISikhululo soMbane soMgangatho weNtsimbi oPhakamileyo Khangela iValve eFakelwe umfanekiso

Umgangatho oPhezulu weSikhululo soMbane weSiteyiti sokuJonga iValve

I-air discharge stop callback ifakwe kumbhobho wokuphuma wempompo yokutya yoxinzelelo oluphezulu lweyunithi yamandla e-thermal ukukhusela umva wamanzi okutya kunye nokukhusela impompo yokutya.Lo mmiselo usebenza ngokuzenzekelayo kunye nokuhamba okuncinci kwempompo yamanzi kunye ne-loop bypass.

Akukho-mthwalo osebenzayo wokuHlola iValve

Iimbonakalo

Yivalve ekhethekileyo ekhawulezayo yokuvala ukukhusela iyunithi yejenereyitha yeinjini yomphunga.Yenzelwe ukunqanda uxinzelelo kwiinjini yomphunga ukuba yehle ngesiquphe xa iyunithi yeinjini yomphunga ilahlekelwa ngumthwalo ngequbuliso, kunye nomphunga okumbhobho wokutsalwa kunye nezifudumezi ezahlukeneyo ukuba ungabuyeli ubuyela kwiinjini yomphunga, nto leyo ebangela amaphiko einjini yeinjini yomphunga ajikelezisayo. Isantya esiphezulu esingaphezulu kwama-3000 ojikelo ngomzuzu ukubaleka umva ngequbuliso, ngaloo ndlela kubangele ingozi eyonyanyekayo yokuba iiblade zeinjini yomphunga zophuke kwaye ijenereyitha yeinjini yomphunga yonakele, Kwaye kuthintelwe ingozi yehamile yamanzi ebangelwe kukuvuza kombhobho wedama lesifudumezi. inkqubo kunye namanzi angena kwi-iturbine esuka kumbhobho wokutsalwa.Kwimeko yeemeko ezingentla, i-valve inokuvalwa ngokukhawuleza ngaphakathi kwe-0.5s.

Usetyenziso:

1. I-pneumatic stop callback kukutyhala ipiston emoyeni ibomvu ngomoya ocinezelweyo, ipiston ityhala ifolokhwe yokutshintsha, kwaye ifolokhwe yokutshintsha iqhube i-rocker shaft ukuba ijikeleze ukuvula ivalve.Ivalve ivalwa ngokutyhala ipiston yegridi yasentlakohlaza umva ukuze inqumle unikezelo lomoya ngohlengahlengiso lwe-electromagnetic.

2. Umphezulu wokutywina we-candy net kunye nesiseko se-ridge senziwe ngezinto zamva nje zokujonga phezulu, ezinokumelana okuqinileyo kunye nokumelana nokuqala.

3. Ukusebenza okuphezulu ukupakisha okutsha, ukutywinwa okuthembekileyo, ukusebenza kakuhle kunye nokuguquguqukayo.

I-Nickel Base Alloy Uxinzelelo oluPhezulu kunye nobushushu bokuhlola iValve

Iimbonakalo:

Ukuze kuqinisekiswe iimfuno eziphakamileyo zokuqina, ukuthembeka kunye nokukhuseleka komnyango wesikrini, umzimba we-valve wenziwe nge-nickel base alloy ngokubanzi, okanye yenziwe kunye ne-welded.Umphezulu wokutywina womnyango wevalve udityaniswe nge-alloy eqinile ukuqinisa ukuxhathisa ukunxiba kunye nokumelana nokukrweleka, kunye nokuphucula ubomi benkonzo yendawo yokutywina.Igumbi eliphakathi lomnyango obanzi lithatha isakhiwo sokuzitywina, esivumela ukutywinwa koxinzelelo oluphezulu.Okukhona uxinzelelo luphezulu, kokukhona lutywinwa ngcono.

Isicelo:

Le mveliso ifanelekile kwiqondo lokushisa eliphezulu, uxinzelelo oluphezulu kunye nezihlandlo ezinobungozi kwi-petrochemical kunye ne-oil refining industry.
