Ubushushu buphantsi ebusika. Ukuba i-ultrasonic flowmeter ifakwe ngaphandle okanye kumbhobho ngaphandle kwemilinganiselo yokukhusela ubushushu, kulula ukuba yonakale ngenxa yokubanda okuphakathi. Ezi ngcebiso zilandelayo zi-5 zingasetyenziselwa ukugcinwa kokungabanda:
Icebiso 1: Yenza umsebenzi olungileyo wokufaka ubushushu kwiipayipi nezixhobo. Songa i-flowmeter kunye nombhobho ngaphakathi kweemitha ezi-3 ngaphambi nasemva kwayo ngokuqinileyo ngekotoni yokufakela ubushushu (kucetyiswa uboya belitye okanye i-polyurethane, kwaye ubukhulu bokufaka ubushushu bumiselwa ngokweqondo lobushushu eliphantsi lendawo, ngokubanzi kungabi ngaphantsi kwe-50mm). Songa umaleko wangaphandle wekotoni yokufakela ubushushu ngelaphu elingangeni manzi ukuthintela imvula nekhephu ukuba zingangeni zize zibangele ukungasebenzi kakuhle kokufaka ubushushu. Kwimimandla ebandayo kumantla eTshayina, intambo yokufakela ubushushu ingafakwa ngaphakathi komaleko wokufakela ubushushu. Amandla entambo yokufakela ubushushu yi-10-20W/m, enokugcina ubushushu bombhobho bungaphezulu kwe-0℃ emva kokuvula ukuthintela ukubanda okuphakathi.
Icebiso lesi-2: Khetha indawo yokufakela ngokufanelekileyo. Zama ukufaka i-flowmeter ngaphakathi okanye kwindawo ekhuselekileyo ukuze uphephe ukuvezwa ngqo ngumoya nekhephu. Ukuba kufuneka ifakwe ngaphandle, kufuneka kwakhiwe ishedi yokukhusela. Ukuphakama kweshedi yokukhusela akufuneki kube ngaphantsi kwe-1.5 yeemitha ukuqinisekisa umoya ococekileyo kunye nokuthintela izixhobo ekubeni zichatshazelwe lilanga ngqo kunye nokumanziswa yimvula.
Icebiso 3: Jonga rhoqo imeko ephakathi. Ebusika, ukuba i-medium elinganisiweyo ngamanzi okanye ezinye izinto ezilula ukuziqandisa, kuyimfuneko ukujonga ubushushu obuphakathi obuboniswa zizixhobo rhoqo yonke imihla. Ukuba ubushushu busondele kwi-0℃, izinga lokuhamba eliphakathi linokonyuswa ngokufanelekileyo (ngokulungisa ivalvu yombhobho), okanye i-antifreeze ingongezwa kwi-medium (kuyimfuneko ukuqinisekisa ukuba i-antifreeze iyahambelana nezixhobo zombhobho kunye nezixhobo ukuze kuthintelwe ukugqwala). Ukuba izixhobo azisetyenziswa ixesha elide, i-medium embhobhoni kufuneka ikhutshwe amanzi ukuze kuthintelwe umonakalo kwizixhobo ngenxa yokuqandisa nokwanda.
Icebiso 4: Jonga ukusebenza kokutywina kwezixhobo. Jonga ukuba umcu werabha wokutywina we-flowmeter casing umdala okanye wonakele na. Ukuba ukutywina akukuhle, imvula nekhephu ziya kungena kwizixhobo zize zibangele umjikelo omfutshane. I-silicone sealant ingasetyenziselwa ukuqinisa iindawo ezitywiniweyo rhoqo. Kwangaxeshanye, jonga ukuba isiciko esingangeni manzi kwi-interface ye-probe silungile na. Ukuba sonakele, kufuneka sitshintshwe ngexesha ukuthintela amanzi ukuba angangeni ngaphakathi kwe-probe.
Icebiso 5: Yenza umsebenzi olungileyo wonyango olungxamisekileyo. Ukuba kufunyaniswe ukuba isixhobo siqandisiwe, musa ukunyanzela ukuba sivule okanye sibethe isixhobo. Okokuqala, vala ivalvu yombhobho ukuze uyeke ukuhamba okuphakathi, uze ugalele kancinci amanzi afudumeleyo (ubushushu obungadluli kwi-60℃) kwindawo eqandisiweyo. Emva kokuba isixhobo sinyibilike ngokupheleleyo, jonga ukuba isixhobo sinamanzi avuzayo na, umonakalo wecandelo kunye nezinye iimeko. Qinisekisa ukuba siqhelekile ngaphambi kokuba usivule.
