Ngaba i-clamp kwi-ultrasonic flow meter ifuna ukupolisha umzobo kwipayipi?

Iimitha zokuhamba ze-ultrasonic ezifakwe kwi-clamp-on zenzelwe ukulinganisa ukuhamba okungengongeneleli, oko kuthetha ukuba zifakelwa ngaphandle eludongeni lwangaphandle lombhobho ngaphandle kokufuna ukunqunyulwa kumbhobho okanye ukudibana ngqo nolwelo olungaphakathi. Ukuba kuyimfuneko ukupolisha umbhobho kuxhomekeke kwizinto ezininzi ezinxulumene nemeko yomphezulu wombhobho kunye nokukwazi kombhobho ukuhambisa nokufumana imiqondiso ye-ultrasonic ngokufanelekileyo. Nantsi inkcazelo eneenkcukacha:

AKUFUNEKI NGOKUQHELEKILEYO UKUPOLISHA

• Imibhobho emitsha okanye emidala kancinci enemibhobho emincinci engaqhelekanga (umz., imibhobho yesinyithi esithambileyo, iPVC, okanye iHDPE).
• Imibhobho enemibhobho ekhanyayo (umz., ipeyinti, izithinteli zokugqwala) okanye umhlwa omncinci, lo gama nje umgquba ubhityile kwaye ufana.
• Imibhobho enemikrwelo emincinci, iimbobo, okanye imithungo ye-weld, ukuba nje ezi aziyivali kakhulu okanye zisasaze imiqondiso ye-ultrasound.

Kunini apho kufuneka khona ukupolisha?

1. Umhlwa Onzima, Isikali, okanye Ukugqwala

• Iingqimba ezixineneyo zomhlwa, isikali, okanye umhlwa kwimibhobho yesinyithi zinokufunxa okanye zisasaze amaza e-ultrasound, zenze buthathaka isignali phakathi komthumeli kunye nomamkeli. Oku kunciphisa ukuchaneka kokulinganisa okanye kubangela ukulahleka kwesignali.
• Isisombululo: Ukupolisha kancinci (umz., ngephepha lesandpaper okanye ngebrashi yentsimbi) ukususa umhlwa/isikali esikhululekileyo kunye nokudala umphezulu othambileyo nococekileyo ukuze kubekho ukudibana okungcono kwe-acoustic.

2. Iingubo ezijiyileyo, ezingafanelaniyo okanye ipeyinti

• Imibhobho enepeyinti etyebileyo (umz., iileya ezininzi), itha, okanye ezinye izinto ezigqunywe ngentsimbi zingasebenza njengemiqobo yesandi. Izinto ezigqunywe ngentsimbi engalinganiyo zinokubangela ukuhanjiswa kwesignali okungahambelaniyo.
• Isisombululo: Ukuba uqweqwe lutyebile (>1–2 mm) okanye aluqhelekanga, ukugquma okanye ukukrwela kancinci indawo apho ii-transducers ziza kufakelwa khona ukuze kuvezwe uqweqwe oluthambileyo noluncinci (okanye isinyithi esingenanto) kunokuphucula ukudibana.

3. Imikrwelo enzulu, iiGouges, okanye iiWeld Protrusions

• Ukungahambi kakuhle komphezulu (umz., imikrwelo enzulu, iintsimbi ze-weld, okanye iimbobo) kwindawo yokufaka i-transducer kunokuphazamisa indlela ye-ultrasonic, okukhokelela ekuphazamisekeni kwesignali.
• Isisombululo: Ukupholisha okuncinci ukuze kuthambise imiphetho ebukhali okanye iindawo ezibonakala zibonakala, ukuqinisekisa ukuba ubuso be-transducer budibana ngokupheleleyo nomphezulu wombhobho.

4. Ukudibanisa okungekuhle kwe-Acoustic

• Isisombululo: Ukupolisha kudala umphezulu othe tyaba nogudileyo, ovumela ijeli ukuba yenze umaleko oqhubekayo, ongenamaqamza ukuze kudluliselwe i-acoustic efanelekileyo.

Izinto Ezibalulekileyo Eziqwalaselweyo Xa Kupholishwa

• Ubungakanani bokupolisha: Yindawo encinci kuphela apho kufakelwa khona ii-transducers (ngesiqhelo ubukhulu be-transducer buphindwe ka-2-3) ekufuneka iqwalaselwe. Inxalenye eseleyo yombhobho ayichukunyiswanga.
• Izinto zombhobho: Kwizinyithi ezithambileyo (ubhedu, i-aluminium) okanye iplastiki, ukugquma kancinci (ngephepha lesandpaper elicolekileyo) kwanele. Kwizinyithi eziqinileyo (intsimbi), ibrashi yocingo okanye iphedi yokurhawuzelela inokufuneka.
• Kuphephe ukupolisha kakhulu: Ukupolisha kakhulu kunokunciphisa udonga lombhobho (okunokubangela umonakalo) okanye kudale umphezulu ogobileyo, osenokubamba umoya. Jonga umphezulu othe tyaba ngokulinganayo.

Xa ukupolisha kungadingeki

• Iipayipi ezithambileyo nezicocekileyo: Iipayipi ezintsha ezineendawo ezigqityiweyo efektri (umz., i-PVC egudileyo, intsimbi engatyiwayo, okanye intsimbi epeyintiweyo enemisonto emincinci, elinganayo) azidingi ukupolisha.
• Ukungcola okuncinci komphezulu: Ukucoca okulula ngelaphu kunye notywala ukususa ukungcola, ioyile, okanye inkunkuma kudla ngokwanela—akufuneki kupolishiwe.
