Imibuzo Nezimpendulo Ezivamile Mayelana Nevalvu Yokukhipha Amafutha Yemishini Yokugcwalisa Amafutha E-MV Ne-HV Transformer

​

Umbuzo 1: Yiziphi izinyathelo zokuphepha zokusebenza nokugcinwa kwe-ivalvu?
A1: Izinyathelo zokuphepha uma usebenza:
1. Ukuhlolwa ngaphambi kokuxhumeka: Ngaphambi kokusebenza, hlola ukuthi izivalo zokuvikela eziku-interface ye-valve ziphelele yini, bese uqinisekisa ukuthi i-interface kanye nezindawo zokuvala azilimele futhi azinazo izinto zangaphandle.
2. Ukuxhumeka okulungile: Sebenzisa amathuluzi afanele (njengesikrufu se-torque) ukuqinisa ukuxhumana nesihlalo se-transformer valve kanye namapayipi emishini yangaphandle ngokwe-torque enconywayo, ukuqinisekisa ukuvalwa kobuso bokugcina okuthembekile nokugwema ukuqinisa ngokweqile noma ukuqinisa kancane.
3. Ukuvula nokuvala kahle: Uma uvula noma uvala ivalvu, phendula isondo lesandla kahle. Ungasebenzisi amathuluzi anjengezingongolo zokwandisa ukuze usebenze ngamandla ukuvimbela umonakalo esiqwini sevalvu noma endaweni yokuvala. Ngemva kokuvula ngokuphelele, kunconywa ukuthi uphendule isondo lesandla kancane ukuze uvikele imicu.
4. Ukuqinisekiswa kwesimo: Ngemva kokusebenza, qinisekisa ngokucacile isimo sevalvu “njengesivuliwe ngokuphelele” noma “sivaliwe ngokuphelele” ngendawo yesondo lesandla noma izimpawu zesikhombisi. Amanye amamodeli afakwe amadivayisi okukhiya, okufanele akhiywe ezindaweni ezibalulekile.
Izinyathelo Zokuqapha Zokulungisa:
Ukuhlolwa okuvamile: Ngaphambi kokulungiswa ngakunye kwe-transformer noma ukwelashwa ngamafutha, hlola ingaphandle le-valve ngamehlo ukuze ubone ukuthi kukhona yini izimpawu zokuvuza, umonakalo, noma ukugqwala.
Ukuhlolwa Komsebenzi: Uma izimo zivuma, ukuhlolwa okulula kokuvala kungenziwa kanye nokuxhumeka kwemishini (njengokubheka ukuqina kwe-vacuum ngemva kokuxhumeka kanye nokuhlanza nge-vacuum).
Ukushintsha isivalo: Uma ukusebenza kwesivalo kwehla ngemva kokusetshenziswa isikhathi eside (njengokuvuza kancane kwamafutha esiqwini sevalvu), abasebenzi abangochwepheshe kufanele bashintshe isivalo sokuvalela noma ama-O-ring besebenzisa iphakheji yezingxenye zokuqala ezisele. Abantu abangebona ochwepheshe akufanele bahlukanise izingxenye eziyinhloko zevalvu ngokwabo.
Umbuzo 2: Indlela yokukhetha okufaneleivalvu yokukhipha uwoyelangama-transformer kanye nemishini yokugcwalisa uwoyela enezincazelo ezahlukene?
A2: Ukukhetha kufanele kucabangele lezi zinhlaka ezilandelayo zokufanisa:
1. Ububanzi kanye nendlela yokuxhuma: Nquma usayizi we-valve port ngokusekelwe kusayizi wesixhumi esibonakalayo sesihlalo se-valve sethangi likawoyela we-transformer (njenge-DN25, DN40, DN50, njll.) kanye nefomu lokuxhuma (njenge-flange standard PN16/DN40, intambo ye-British NPT, njll.) ukuqinisekisa ukuxhumana okungokoqobo.
2. Izinga lokucindezela kanye ne-vacuum: Qinisekisa ukuthi ingcindezi yokuklama kanye nezinga le-vacuum le-valve kuhlangabezana noma kudlula ingcindezi ephezulu yokusebenza kanye nezinga eliphezulu lokusebenza le-vacuum elidingwa yimishini yokugcwalisa uwoyela (njenge-vacuum pump, i-oil pump) kanye nobuchwepheshe bokucubungula i-transformer.
3. Ukuhambisana kwamafutha okuvikela: Qinisekisa ukuthi zonke izinto zokuvala kanye nezinto ezithinta uwoyela we-valve ziyahambisana ngokuphelele nohlobo lwamafutha okuvikela owasebenzisayo (njengamafutha amaminerali, uwoyela we-silicone, i-ester yokwenziwa).
Indawo yokusebenza: Cabanga ukuthi iyindawo evamile yangaphakathi/yangaphandle noma inezidingo ezikhethekile (njengokubanda okuphezulu, izinga lokushisa eliphezulu, ukufuthwa ngosawoti, njll.) ukuze kutholakale ukuthi izinto ezikhethekile zegobolondo noma ukwelashwa kwendawo kuyadingeka yini.
Q3: Ungaqinisekisa kanjani futhi uqinisekise ikhwalithi nokuthembeka kwama-valve?
A3: Siqinisekisa ikhwalithi yevalvu ngayinye ngezinqubo eziqinile zokukhiqiza nokuhlola:
Ukuhlolwa kokuqina komoya: Uma ivalvu ivaliwe, igesi eyomile nehlanzekile (njengomoya noma i-nitrogen) igcwaliswa emgodini wevalvu ngengcindezi ethile. Ingcindezi iyagcinwa ukuze kuhlolwe noma yikuphi ukuvuza, kuqinisekiswa ukusebenza kwayo kokuvala ngaphansi kwengcindezi enhle.
Ukuhlolwa kokuvala i-vacuum: Ukuphela kwevalvu eyodwa kuvaliwe, kanti okunye kuxhunywe kuphampu ye-vacuum. Ikhishwa iye ezingeni eliphakeme le-vacuum elicacisiwe (njengangaphansi kwe-10 Pa), futhi izinga lokwehla kwe-vacuum level liyahlolwa ngaphakathi kwesikhathi esithile ukuqinisekisa ukusebenza kwayo kokuvala ngaphansi kwe-vacuum ephezulu.
Ukuhlolwa kohlobo: Kuthathwa amasampula njalo ukuze kuhlolwe impilo ephelele (njengokuhlolwa komjikelezo wokuvula nokuvala), ukuhlolwa komjikelezo wokushisa okuphezulu nokuphansi, kanye nokuhlolwa kokuhambisana namafutha okuvikela, njll., ukuqinisekisa ukuthembeka kwesikhathi eside komklamo.
