Ukuthelekiswa kweMetric Thread kunye neBSP Thread

 Umahluko phakathi kwemisonto emibini

Xa kuziwa kwiinkqubo zokuzila, ukuqonda umahluko phakathi kwentambo ye-metric kunye nentambo ye-BSP kubalulekile. Zombini ezi ndidi zemisonto ziqhele ukusetyenziswa kumashishini ahlukeneyo, kodwa ziyahluka ngokweendlela zazo zokulinganisa, ifom yentambo, i-pitch, kunye ne-engile. Ukukunceda ukuba uqonde ngcono, masithelekise le misonto mibini kwitheyibhile ecacileyo nemfutshane yokuthelekisa:

Umba	Metric Thread	BSP Thread
Ifom yomsonto	I-Symmetric emile okwe-V	I-rounded crest kunye neengcambu
I-pitch	Libonakaliswe ngeemilimitha (mm)	Inani lemisonto nge-intshi nganye (TPI)
Iengile	I-60-degree ifakiwe engile	I-55-degree ifakiwe engile
Izicelo eziqhelekileyo	Ukusetyenziswa kwenjongo ngokubanzi kuwo wonke amashishini	Ukudityaniswa kwemibhobho, imibhobho

 

Ukwahluka kwifom yentambo, i-pitch, kunye ne-engile

Umahluko wokuqala ophawulekayo phakathi kwentambo yemetric kunye nentambo ye-BSP ilele kwifom yabo yentambo.

Uguqulo kunye nokuhambelana

Nika isikhokelo ekuguquleni phakathi komsonto we-metric kunye nomsonto we-BSP

Xa kuziwa ekuguquleni phakathi kwentambo ye-metric kunye nentambo ye-BSP, kubalulekile ukuba ube nokuqonda okucacileyo kweeyantlukwano eziphambili phakathi kwezi ntlobo zimbini zentambo. Intambo yeMetric yifomu yentambo esemgangathweni esetyenziswa ikakhulu eYurophu nakwezinye iindawo zehlabathi, ngelixa i-BSP (i-British Standard Pipe) intambo isetyenziswa kakhulu e-United Kingdom nakwamanye amazwe aphenjelelwa yimigangatho yobunjineli baseBritani. Ukuguqula phakathi kwezi ntlobo zimbini zentambo kunokuba yinkqubo enzima, kodwa ngesikhokelo esifanelekileyo, kunokwenziwa ngokufanelekileyo.

Ukuguqula phakathi kwentambo ye-metric kunye nentambo ye-BSP, kubalulekile ukuba nolwazi olunzulu lwe-pitch yentambo, i-diameter, kunye neemfuno ezithile zesicelo. I-pitch yentambo ibhekisela kumgama ophakathi kwemisonto emeleneyo, ngelixa i-diameter imele ubukhulu bomsonto. Ezi zinto zidlala indima ebalulekileyo ekuqinisekiseni ukuhambelana kunye nokutshintshiselana kwemisonto.

Imingeni kunye nokuqwalaselwa xa uguqulela phakathi kweentlobo ezimbini zentambo

Ukuguqula phakathi kwentambo ye-metric kunye nentambo ye-BSP kunokubonisa imingeni emininzi kunye nokuqwalaselwa. Enye yeengxaki eziphambili ngumahluko kwiiprofayili zentambo. Intambo ye-Metric ineprofayili ye-trapezoidal, ngelixa intambo ye-BSP ineprofayili ejikelezayo. Oku kuthetha ukuba imicu ayinayo imilo efanayo, enokwenza kube nzima ukufezekisa ukulingana okufanelekileyo xa uguqula phakathi kwezi zibini.

Olunye uqwalaselo ngumahluko kwimigangatho yemisonto. I-Metric thread ilandela imigangatho ye-ISO (i-International Organization for Standardization), ngelixa intambo ye-BSP ibambelela kwiMigangatho yaseBritani. Le migangatho ichaza imilinganiselo ethile kunye nokunyamezelwa kwemisonto, kwaye ukungahambisani nayo kunokukhokelela kwimiba yokuhambelana.

Ukongezelela, inkqubo yokuguqulwa inokufuna ukusetyenziswa kwee-adapters okanye izixhobo zokuqinisekisa uxhulumaniso olufanelekileyo phakathi kwentambo ye-metric kunye ne-BSP thread. Eziadaptha okanye izifakelo zisebenza njengabalamli, zivumela uguqulo phakathi kweentlobo ezimbini zemisonto. Nangona kunjalo, kubalulekile ukukhetha i-adapters ezikumgangatho ophezulu ezilungiselelwe ukuguqulwa okuthe ngqo, njengoko ukusebenzisa ii-adapters ezingahambelaniyo okanye ezisezantsi kunokukhokelela ekuvuzeni okanye ezinye iingxaki.

Nayiphi na imiba yokuhambelana enokuthi ivele ngexesha lokuguqulwa

Ngexesha lokuguqulwa phakathi kwentambo ye-metric kunye nentambo ye-BSP, imiba yokuhambelana ingavela, ngakumbi ukuba ukuguqulwa akwenziwanga ngokuchanekileyo. Omnye umba wokuhambelana oqhelekileyo ngumahluko kwipitch yentambo. Umsonto we-Metric unomsonto ocolekileyo xa kuthelekiswa nentambo ye-BSP, nto leyo ethetha ukuba imisonto isenokungahambelani ngokugqibeleleyo xa iguqulwa phakathi kwezi zimbini. Oku kunokubangela uxhulumaniso olukhululekileyo okanye olungazinzanga, lubeka esichengeni ukuthembeka kwesicelo.

Omnye umba wokuhambelana ngumahluko kwidayamitha yomsonto. Intambo ye-Metric kunye nentambo ye-BSP inemilinganiselo eyahlukeneyo yedayamitha, kwaye ukuba ukuguqulwa akwenziwanga ngokuchanekileyo, kunokukhokelela ekungafanini phakathi kwemisonto. Oku kunokubangela ukuvuza okanye eminye imiba, njengoko imisonto isenokungatywinwa kakuhle.

Ngapha koko, umahluko kwimigangatho yemisonto nako unokuba negalelo kwimiba yokuhambelana. Intambo ye-Metric kunye nentambo ye-BSP inemigangatho eyahlukeneyo, oku kuthetha ukuba imilinganiselo kunye nokunyamezela kunokwahluka. Ukuba ukuguqulwa akwenziwanga ngokwemigangatho efanelekileyo, kunokubangela ukungasebenzi kakuhle okanye ukungasebenzi kakuhle kwesicelo.

Ukuqukumbela

Ukuqukumbela, imisonto yemetric kunye nemisonto ye-BSP zombini zibalulekile kumashishini ahlukeneyo ngezibonelelo zabo ezithile. Imisonto yeMetric inikezela ngokuchaneka, ukuhambelana, kunye nokutshintshiselana, ngelixa iintambo ze-BSP zibonelela ngokuthembeka kunye nokuhambelana nenkqubo yobukhosi. Ukhetho phakathi kwezi zibini luxhomekeke kwiimfuno ezithile kunye nemigangatho yoshishino okanye isicelo. Ukuguqula phakathi kwentambo ye-metric kunye nentambo ye-BSP kufuna ukuqwalaselwa ngononophelo kunye nokuthotyelwa kwiimfuno ezithile zesicelo, kubandakanywa nokukhetha iiadaptha ezifanelekileyo okanye ukufakwa. Ngokuqonda iiyantlukwano eziphambili kunye nokuqwalasela imingeni kunye nemiba ehambelanayo, ukuguqulwa okuphumelelayo kunokufezekiswa, ukuqinisekisa ukusebenza kakuhle kunye nokusebenza.

Imibuzo ebuzwa qho

Umbuzo:  Ngowuphi umahluko ophambili phakathi komsonto we-metric kunye nentambo ye-BSP?

A:  Iiyantlukwano eziphambili phakathi kwentambo ye-metric kunye nentambo ye-BSP ilele kuyilo lwabo kunye neenkqubo zokulinganisa. Imisonto yemetriki ilandela inkqubo yokulinganisa i-metric, isebenzisa iimilimitha kwi-pitch yentambo kunye nedayamitha. Iintambo ze-BSP, kwelinye icala, zisebenzisa inkqubo yokulinganisa iMibhobho yoMgangatho waseBritani, enemisonto yepitch elinganiselwa kwimisonto nge-intshi nganye kunye nedayamitha elinganiswa ngee-intshi.

Umbuzo:  Ngaba intambo yemetric ingasetyenziswa ngokutshintshanayo kunye nentambo ye-BSP?

A:  Imisonto yeMetric kunye neentambo ze-BSP azitshintshi ngenxa yeendlela ezahlukeneyo zokulinganisa kunye noyilo. Imisonto ye-Metric ine-pitch ecolekileyo kunye ne-engile yomsonto eyahlukileyo xa kuthelekiswa nemisonto ye-BSP. Ukuzama ukuzitshintsha kunokukhokelela ekulinganeni okungafanelekanga, ukuvuza, okanye umonakalo kumalungu anemisonto.

Umbuzo:  Ngaba kukho nayiphi na imibutho yokulinganisa intambo ye-metric kunye nentambo ye-BSP?

A:  Ewe, kukho imibutho yokumisela yomibini intambo yemetric kunye neBSP. I-International Organisation for Standardization (ISO) ibeka imigangatho yemisonto yemetric, iqinisekisa ukuhambelana kunye nokufana kumazwe onke. Kwimicu ye-BSP, iZiko leMigangatho yaseBritani (BSI) inoxanduva lokuseka nokugcina imigangatho.

Q:  Ngawaphi amashishini asebenzisa kakhulu intambo yemetric?

A:  Imisonto yeMetric isetyenziswa kakhulu kumashishini afana neemoto, oomatshini, kunye nokuvelisa. Ngokuqhelekileyo zifumaneka kumazwe aseYurophu naseAsia apho inkqubo yemetric yinkqubo yokulinganisa esemgangathweni. Imisonto ye-Metric inikezela ngoqhagamshelo oluchanekileyo noluthembekileyo, lubenza bafaneleke kwizicelo ezahlukeneyo.

Umbuzo:  Ngaba kukho naziphi na iingenelo zokusebenzisa intambo ye-BSP kumsonto we-metric?

A:  Imisonto ye-BSP ineenzuzo kwizicelo ezithile. Ngokuqhelekileyo zisetyenziswa kwiinkqubo zemibhobho kunye ne-hydraulic, ngakumbi kumazwe alandela inkqubo yokulinganisa yaseBritani. Imisonto ye-BSP inoyilo lwe-taper, oluvumela itywina elingqongqo kunye nokuchasana ngcono ukuvuza xa kuthelekiswa nemisonto yemetric.

Umbuzo:  Ngaba intambo ye-metric kunye ne-BSP ingaguqulwa ngokulula?

A:  Ukuguqula phakathi komsonto we-metric kunye nentambo ye-BSP kufuna ukuqwalaselwa ngononophelo kwaye akunakufezekiswa ngokulula. Iinkqubo ezahlukeneyo zokulinganisa, ii-angles zentambo, kunye ne-pitches zenza uguqulo oluthe ngqo lube ngumngeni. Kwezinye iimeko, iiadaptha okanye izifakelo ezinemisonto ehambelanayo zinokusetyenziselwa ukudibanisa amacandelo aneentlobo ezahlukeneyo zentambo. Nangona kunjalo, kucetyiswa ukuba kusetyenziswe uhlobo olufanelekileyo lwentambo yokusebenza ngokufanelekileyo kunye nokhuseleko.
