Indlela Yokukala Nokukhetha Ngokunembile Izimfuneko Ze-Hose Clamp?

Isinyathelo esibaluleke kakhulu ekukaleni nasekukhetheni ngokunembile imininingwane yama-hose clamps ukukala "ububanzi obukhulu obungaphandle (O.D.)" we-hose ngemva kokufakwa. Abasebenzisi abaningi bathenga ama-hose clamps ngokungalungile besebenzisa ububanzi obungaphakathi be-hose, okuholela ekungafanini kosayizi. Indlela efanele ukufaka i-hose ngokugcwele esixhumeni (njenge-barbed fitting noma ipayipi le-aluminium) bese usebenzisa i-caliper ukukala umjikelezo noma ububanzi engxenyeni ejiyile yokuxhumana. Ububanzi obukhethiwe be-hose clamp kumele buqinisekise ukuthi leli nani elikaliwe liwela phakathi kwe-"minimum diameter" ne-"maximum diameter," futhi okufanele kube phakathi nendawo ukuze kutholakale amandla okufinyeza afanele.

Ekugcineni kwemisebenzi yezimboni noma ukulungisa izimoto, ukukhetha usayizi ongalungile we-hose clamp kungaholela ezinkingeni ezincane njengokuvuza noma izinkinga ezinkulu njengokuhlukaniswa kwe-hose. Sicela ulandele le nqubo yokulinganisa yobungcweti:

Ungalinganisi i-hose isesimweni sayo semvelo. Ngoba ama-hose anwebeka futhi i-fitting izokhulisa udonga lwepayipi ngemva kokufakwa, ukulinganisa kufanele kwenziwe ngemva kokuba i-hose ifakwe ku-connector. Leli nani libizwa ngokuthi i-installed outer diameter.

Kunconywa ukuthi usebenzise i-caliper ukulinganisa amaphuzu amaningi bese uthatha isilinganiso. Uma i-caliper ingatholakali, ungafaka intambo encane ezungeze ipayipi ukulinganisa umjikelezo, bese usebenzisa ifomula Ububanzi = Umjikelezo / 3.14 ukubala ububanzi.

Lapho ukhetha izinsimbi zokubopha amahose e-stainless steel, gwema amanani aphezulu naphansi kakhulu wezicaciso. Isibonelo, uma ububanzi obulinganiselwe bungu-26mm, nakuba kokubili u-25-38mm no-16-27mm kungakwazi ukukumboza, ukukhetha u-25-38mm kuphephile ngoba u-27mm useduze nomkhawulo ophezulu, futhi ukuntuleka kwesilinganiso sokulungisa isikulufu kungaholela ekuntuleni kwamandla okuqinisa.

Ngaphezu kobubanzi, ububanzi be-hose clamp nakho kuyisici esibalulekile esithinta umphumela wokuvala.

Amahose amancane obubanzi (anjengemigqa kaphethiloli, imigqa ye-vacuum): Ngokuvamile, kusetshenziswa ama-hose clamp esitayela saseMelika anobubanzi obungu-8mm noma 9mm. Ibhande lensimbi elincane lingagxilisa ingcindezi enkulu endaweni encane.

Amahose aphakathi nendawo kuya kukhulu obubanzi (anjengamahose e-radiator, amashubhu okungenisa umoya): Sincoma ukukhetha ama-hose clamp anesisindo esinzima anobubanzi obungu-12.7mm noma 14.2mm. Indawo yokuthintana ebanzi ivikela ngempumelelo ukuthi ihose lingasiki futhi linikeza ukuvala okulinganayo okungu-360 degrees.

Njengomkhiqizi we-clamp ochwepheshile, sincoma ukubeka kuqala ama-hose clamp ensimbi engagqwali engu-304 noma 316 kunoma iyiphi indawo enengcindezi ephezulu noma yangaphandle.

Ukumelana nokugqwala: Amabhande e-hose clamp ensimbi ekwalithi ephezulu amelana nokugqwala okubangelwa imvula, i-coolant, kanye namafutha enjini, evimbela ukugqwala kwezikulufu okungenza kube nzima ukukhipha.

Amandla okukhathala: Amabhande ensimbi anamandla amakhulu awavamile ukuyekelela ezindaweni ezishintshana ukushisa nokubanda (njengezindawo zenjini), agcine ingcindezi yokubamba isikhathi eside.

Ukukhiqizwa ngokunembile: Izinhlangothi ze-hose clamp ezifanele kufanele zigobe noma zipholishwe ukuze ziqinisekise ukuthi aziklwebhi ubuso bamahose abizayo ngesikhathi sokuqinisa.

Uma uthenga ama-hose clamp, khumbula: "Linganisa ububanzi obungaphandle, hlola impahla, bese ukhetha ububanzi bebhande." I-hose clamp enosayizi ofanele ayinikezi nje kuphela ukuvala okuphelele, kodwa futhi inweba impilo yokusebenza ye-hose futhi yehlisa izindleko zokulungisa esikhathini esizayo.
