Izinketho ezivamile zihlanganisa insimbi engagqwali (esebenza ngezindlela ezihlukahlukene kakhulu), i-Inconel (yezinhlelo zokusebenza ezinezinga eliphezulu lokushisa), noma i-Titanium (uma i-lightweight nokugqwala kubalulekile). Xhumana nochwepheshe noma bhekisa izidingo zakho zohlelo lokusebenza ukuze uthole isiqondiso esifanele ekukhetheni izinto.
Ingabe izifutho zensimbi ezishiselwe emaphethelweni zingalungiswa?
Ukulimala konqenqema lwensimbi eshiselwe kungenza kube sengozini ubuqotho nokusebenza kwayo. Kuye ngezinga lomonakalo nendawo yokuqhekeka/ukuvuza, kungase kwenzeke ukulungisa izivungulo ngokuvala noma ukuchibiyela ukuvuza noma imifantu. Kodwa-ke, khumbula ukuthi ukulungiswa kwe-weld kungashintsha izici zokuguquguquka komhlangano. Hlala uthintana nochwepheshe ngaphambi kokuzama noma yikuphi ukulungisa noma ufune ukuhlolwa kochwepheshe.
Ibhonga lensimbi elishiselwe ngokuvamile lihlala isikhathi esingakanani?
Impilo yesevisi yensimbi eshiselwe onqenqemeni incike ezintweni ezihlukahlukene ezifana nempahla, ikhwalithi yenqubo yokukhiqiza, izithiyo ezikhona ekwakhiweni kwayo, izimo zemvelo zokusebenza njengemijikelezo yokucindezela kanye nokushintshashintsha kwezinga lokushisa okuthinta impilo yokukhathala. Ukuze uthuthukise impilo ende, landela imihlahlandlela yokufaka efanele kanye nezinqubo zokulungisa ezivamile.
Ingabe zikhona ezinye izindlela zokusebenzisa izivuno zensimbi ezishiselwe onqenqemeni kuhlelo lwami lokusebenza?
Kunezinye izindlela ezimbalwa ezitholakalayo kuye ngezidingo zakho zohlelo lokusebenza. Ezinye izindlela ezivamile zifaka izigxivizo ze-diaphragm (zamathuluzi okulinganisa ingcindezi), izimpawu ezilayishwa entwasahlobo (zokusebenza ngokujikeleza), kanye ne-hydraulic/pneumatic piston or rod seals. Kodwa-ke, kubalulekile ukuhlola indawo yokusebenza, izidingo zokunyakaza, kanye nokwakheka kohlelo lonke ngaphambi kokukhetha obunye ubuchwepheshe.
Ingabe kungenzeka ukwenza ngokwezifiso imibhobho yensimbi eshiselwe onqenqemeni?
Yebo, imibhobho yensimbi eshiselwe unqenqema ingenziwa ngendlela oyifisayo ngokusekelwe ezidingweni ezithile zohlelo lokusebenza, njengokukhethwa kwempahla, i-geometry ene-bellow (isibalo se-convolution nobude), ukucushwa kwama-flange, kanye nohlobo lophawu. Sebenza nomkhiqizi onedumela elihle noma ithimba lonjiniyela eligxile kwizixazululo zangokwezifiso ukuze uqinisekise ukusebenza okuphelele nokuhambisana kwezinto zohlelo lwakho lokusebenza oluhlukile.
Ekuphetheni
Sengiphetha, imibhobho yensimbi eshiselwe onqenqemeni iyizingcweti ezifanelekile zokuxazulula izinkinga zokubhekana nezinselele ekubekweni uphawu okuguquguqukayo nokuvumelana nezimo. Ngokuhlinzeka ngendawo evalwe kahle, ukwethembeka okumangalisayo, amandla okwenza ngokwezifiso, kanye neminyaka yokuphila ehlaba umxhwele, lezi zingxenye ezihlakaniphile zimi ngomumo ukubhekana nezicelo zakho zobunjiniyela ezidinga kakhulu. Ungavumeli izici ezikhawulelayo zithiye izifiso zakho zedizayini - yamukela amakhono ensimbi eshiselwe onqenqemeni futhi uthole izixazululo eziguqukayo namuhla!
