Umboniso weMveliso
Inzuzo yeMveliso
Ukusetyenziswa okuphambili:
1) Igesi yesixeko: umbhobho wokukhupha igesi, umbhobho ophambili kunye nombhobho wokubonelela ngomgca wesebe, njl.njl.
2) Ubushushu obuphakathi: imibhobho yokuphuma, imigca ephambili kunye nemigca yamasebe ezixhobo ezinkulu zokufudumeza.
3) Isitshintshi sobushushu: vula kwaye uvale imibhobho kunye neesekethe.
4) Izityalo zentsimbi: imibhobho eyahlukeneyo yolwelo, imibhobho yokukhupha igesi ephumayo, imibhobho yokubonelela ngegesi kunye nobushushu, imibhobho yokubonelela ngepetroli.
5) Izixhobo ezahlukeneyo zoshishino: iipayipi ezahlukeneyo zonyango lobushushu, iipayipi ezahlukeneyo zegesi zoshishino kunye nobushushu.
Iimbonakalo:
1) Ivalvu yebhola edityanisiweyo ngokupheleleyo, akuyi kubakho kuvuza kwangaphandle nezinye izinto.
2) Inkqubo yokucubungula i-sphere ilandelwa kwaye ifunyanwe yi-detector yekhompyutha ephucukileyo, ngoko ke ukuchaneka kokucubungula i-sphere kuphezulu.
3) Ekubeni izinto zomzimba wevalvu zifana nezo zombhobho, akuyi kubakho xinzelelo lungalinganiyo kwaye akuyi kubakho tshintsho ngenxa yeenyikima kunye nezithuthi ezidlula emhlabeni, kwaye umbhobho awugugi.
4) Umzimba weringi yokutywina wenziwe ngezinto ze-RPTFE ezinomxholo we-25% weCarbon (carbon) ukuqinisekisa ukuba akukho kuvuza (0%).
5) Ivalvu yebhola edityanisiweyo egqunywe ngqo ingangcwatywa ngqo emhlabeni, ngaphandle kwesidingo sokwakha imingxuma yeevalvu ephakamileyo nenkulu, kufuneka nje ukuseta imingxuma emincinci enganzulu emhlabeni, nto leyo egcina kakhulu iindleko zokwakha kunye nexesha lobunjineli.
6) Ubude bomzimba wevalvu kunye nokuphakama kwesiqu sevalvu kunokulungiswa ngokweemfuno zokwakha kunye noyilo lombhobho.
7) Ukuchaneka komatshini wesphere kuchanekile kakhulu, umsebenzi ulula, kwaye akukho kuphazamiseka okubi.
8) Ukusetyenziswa kwezinto eziluhlaza eziphambili kunokuqinisekisa uxinzelelo olungaphezulu kwe-PN25.
9) Xa kuthelekiswa neemveliso zeenkcukacha ezifanayo kushishino olufanayo, umzimba wevalvu mncinci kwaye umhle ngenkangeleko.
10) Phantsi kwemeko yokuqinisekisa ukusebenza okuqhelekileyo nokusetyenziswa kwevalvu, ubomi benkonzo bungaphezulu kweminyaka engama-20.
