Isingeniso Somsebenzi
Ukuvalwa okuzenzakalelayo kokucindezela ngokweqile
Lapho isilawuli sokucindezela esingaphambili ekupheleni kwepayipi legesi sisebenza ngendlela engavamile noma umfutho wepayipi uphezulu kakhulu ngenxa yokuhlolwa komfutho wepayipi okwenziwa inkampani yegesi, futhi udlula inani lokusetha ukucindezela okungaphezulu kwephayiphi igesi ezivalayo, i-valve. izovala ngokuzenzakalelayo ngenxa yokucindezela ngokweqile ukuvimbela ukucindezela okubangelwa ukucindezela kwepayipi.Iphezulu kakhulu futhi ukuvuza kwegesi kwenzeka.
Ukuvalwa okuzenzakalelayo ngaphansi kwengcindezi
Lapho isilawuli sokucindezela esisekupheleni kwepayipi legesi singejwayelekile, phakathi nenkathi ephezulu yokusetshenziswa kwegesi, ipayipi legesi liyaba yiqhwa futhi livinjwe, ukushoda kwegesi ebusika, ukuvala igesi, ukushintshwa kwegesi, ukushintshwa, ukucindezelwa kanye neminye imisebenzi kubangela ukucindezela kwepayipi. yehla futhi iwe ngaphansi kwenani elibekiwe, I-valve izovala ngokuzenzakalelayo ngaphansi kwengcindezi ukuvimbela izingozi zokuvuza kwegesi ezingase zenzeke lapho umfutho womoya ubuyiselwa.
Ukuvala okuzenzakalelayo okuchichimayo
Lapho isishintshi somthombo wegesi kanye nesilawuli sokucindezela kwephayiphi legesi esisekupheleni-ekugcineni kungavamile, noma ipayipi lerabha liyawa, ubudala, ukugqabuka, ipayipi le-aluminium-plastic kanye nepayipi lensimbi kubhobozwa ukugqwala kukagesi, imifantu ivela ezinguqukweni zengcindezi, ukuxhuma kukhululekile, futhi isitofu segesi asijwayelekile, njll., Lapho ukugeleza kwegesi epayipini kuchichima isikhathi eside futhi kudlula inani elibekiwe lokugeleza okudlulele kwe-valve, i-valve izovala ngokuzenzakalelayo ngenxa ye-overcurrent, ukuphazamisa. ukunikezwa kwegesi, nokuvimbela izingozi zokuphepha ezingaba khona ezibangelwa ukuphuma kwegesi ngokweqile.
Umyalelo Wokusetshenziswa
Isimo sokuvaleka sokuqala sevalvu
isimo esijwayelekile sokusebenza
I-undervoltage noma ukuzivala kwe-overcurrent
ukuzivala ngokucindezela ngokweqile
1. Esimweni esivamile sokunikezwa komoya, phakamisa ngobumnene inkinobho yokuphakamisa i-valve (vele uyiphakamise ngobumnene, ungasebenzisi amandla amaningi), i-valve izovuleka, futhi inkinobho yokuphakamisa izosethwa kabusha ngokuzenzakalelayo ngemva kokuyikhulula.Uma inkinobho yokuphakamisa ingakwazi ukusethwa kabusha ngokuzenzakalelayo, sicela ucindezele ngesandla inkinobho yokuphakamisa ukuze usethe kabusha.
2. Isimo esivamile sokusebenza se-valve siboniswa emfanekisweni.Uma kudingekile ukuphazamisa ukunikezwa kwegesi komshini wegesi ngesikhathi sokusetshenziswa, kuyadingeka kuphela ukuvala i-valve manual ekupheleni kokuphuma kwe-valve.Kuvinjelwe ngokuqinile ukucindezela imodyuli yenkomba ngesandla ukuze uvale ngokuqondile i-valve.
3. Uma i-module yenkomba yehla futhi ivala i-valve ngesikhathi sokusetshenziswa, kusho ukuthi i-valve ingene ngaphansi kwe-undervoltage noma isimo sokuzivala ngokweqile (njengoba kuboniswe esithombeni).Abasebenzisi bangazihlola ngezizathu ezilandelayo.Ezinkingeni ezingakwazi ukuxazululwa ngokwazo, kufanele zixazululwe yinkampani yegesi.Ungayixazululi uwedwa, izizathu ezingaba zimi kanje:
(1) Ukunikezwa kwegesi kuphazamisekile noma umfutho wepayipi uphansi kakhulu;
(2) Inkampani yegesi imisa igesi ngenxa yokulungiswa kwemishini;
(3) Amapayipi angaphandle alinyazwa yizinhlekelele zemvelo ezenziwe abantu;
(4) Abanye ekamelweni Ivalvu yokuvala izimo eziphuthumayo ivaliwe ngenxa yezimo ezingavamile;
(5) Ipayipi lerabha liyawa noma into esebenza ngegesi ayijwayelekile (njengokuvuza kwegesi okubangelwa ukushintsha okungavamile);
4. Ngesikhathi sokusetshenziswa, uma imodyuli yenkomba itholakala ukuthi ikhuphukele endaweni ephakeme kakhulu, kusho ukuthi i-valve isesimweni sokuzivala ngokweqile (njengoba kuboniswe esithombeni).Abasebenzisi bangakwazi ukuzihlola ngezizathu ezilandelayo futhi bazixazulule ngenkampani yegesi.Ungakuxazululi uwedwa.Ngemva kokuxazulula inkinga, cindezela imojula yenkomba ukuze ubuyisele i-valve esimweni sokuqala sokuvala, bese uphakamisa inkinobho yokuphakamisa i-valve futhi ukuze uvule i-valve.Izimbangela ezingenzeka ze-overpressure autism zihlanganisa okulandelayo:
(1) Isilawuli somfutho ongaphambili wepayipi legesi asisebenzi kahle;
(2) Inkampani yegesi yenza imisebenzi yamapayipi.Ukucindezela kwamapayipi okwedlulele ngenxa yokuhlolwa kwengcindezi;
5. Ngesikhathi sokusetshenziswa, uma uthinta ngephutha imojula yenkomba, okwenza i-valve ivale, udinga ukuphakamisa inkinobho ukuze uvule kabusha i-valve.
