BSPP, yomwe imadziwikanso kuti British Standard Pipe Parallel, ndi mtundu wa ulusi womwe uli ndi mapangidwe ofanana.Amagwiritsidwa ntchito nthawi zambiri ngati chisindikizo chothina chotsitsa chikufunika.Ulusi woterewu nthawi zambiri umapezeka m'ma hydraulic systems, komanso m'makina a mpweya ndi mpweya.Ulusi wa BSPP umadziwika chifukwa chosavuta kukhazikitsa komanso kuthekera kwake kuthana ndi kuthamanga kwambiri.
Kumbali ina, BSPT, kapena British Standard Pipe Taper, ndi mtundu wa ulusi umene uli ndi mapangidwe a taper.Izi zikutanthauza kuti m'mimba mwake wa ulusiwo umachepa kutalika kwake.Ulusi wa BSPT umagwiritsidwa ntchito kwambiri popanga mapaipi ndi mapaipi oyenera.Amapereka chisindikizo chodalirika ndipo amatsutsana ndi kugwedezeka, kuwapanga kukhala oyenerera kumadera otsika kwambiri komanso otentha kwambiri.
Ulusi wa R, womwe umadziwikanso kuti American National Standard Taper Pipe Thread, ndi ofanana ndi ulusi wa BSPT malinga ndi kapangidwe kake ka taper.Komabe, ulusi wa R uli ndi ngodya yosiyana ndipo amagwiritsidwa ntchito ku North America.Ulusi umenewu nthawi zambiri umapezeka m'mapaipi ndi makina opangira mapaipi, komanso m'makampani amafuta ndi gasi.Ulusi wa R umapereka kulumikizana kotetezeka komanso kotayikira.
Pomaliza, ulusi wa Rc, kapena British Standard Pipe Parallel/Conical, amaphatikiza mawonekedwe a ulusi wofanana ndi wa taper.Ulusi uwu uli ndi gawo lofananira kutsogolo ndi gawo la taper kumbuyo.Ulusi wa Rc umagwiritsidwa ntchito nthawi zambiri pamagwiritsidwe pomwe chisindikizo chimafunikira, monga ma hydraulic system ndi ma gauge okakamiza.
Posankha ulusi woyenera pa ntchito inayake, ndikofunika kulingalira kugwirizana kwa ulusi ndi dongosolo lomwe liripo.Izi zikuphatikizapo zinthu monga kukula kwa ulusi, phula, ndi njira yosindikizira.M'pofunikanso kuganizira mmene ntchito dongosolo, kuphatikizapo kutentha, kuthamanga, ndi kukhalapo kwa zinthu zikuwononga.
Mapeto
Nkhaniyi ikugogomezera kufunikira komvetsetsa kusiyana pakati pa BSPP, BSPT, R, ndi Rc ulusi posankha mtundu woyenera wa ulusi mu ma plumbing ndi ma hydraulic systems.Imawunikira zabwino ndi mawonekedwe amtundu uliwonse wa ulusi, monga kuphweka kwa kukhazikitsa, makina osindikizira, kugwirizana ndi mitundu ina ya ulusi, ndi mitundu yogwiritsira ntchito.Nkhaniyi ikugogomezeranso kufunikira koganizira zofunikira zenizeni, monga kuthamanga kwa magazi, chitetezo cholumikizira, kuwongolera kupanikizika, komanso chilengedwe posankha mtundu woyenera wa ulusi.Ponseponse, kusankha mtundu wolondola wa ulusi ndikofunikira pakuwonetsetsa kudalirika, kuchita bwino, komanso magwiridwe antchito a makina kapena zida zomwe zimagwiritsidwa ntchito.
Mafunso Ofunsidwa Kawirikawiri
Q: Kodi pali kusiyana kotani pakati pa ulusi wa BSPP ndi BSPT?
A: Ulusi wa BSPP (British Standard Pipe Parallel) uli ndi mawonekedwe a ulusi wofanana, pamene ulusi wa BSPT (British Standard Pipe Taper) uli ndi mawonekedwe a ulusi wa tapered.Ulusi wa BSPP uli ndi malo osindikizira pa ulusi wokha, pamene ulusi wa BSPT umadalira pawiri yosindikiza kapena tepi.
Q: Kodi ulusi wa BSPP ndi BSPT ungagwiritsidwe ntchito mosiyana?
A: Ulusi wa BSPP ndi BSPT sizisinthana chifukwa cha mawonekedwe awo osiyanasiyana.Kuyesera kuzigwiritsa ntchito mosinthana kungayambitse kutayikira kapena kusindikiza kosayenera.Ndikofunika kugwiritsa ntchito mtundu wolondola wa ulusi pa ntchito yeniyeni.
Q: Kodi ulusi wa R ndi Rc umasiyana bwanji ndi ulusi wa BSPP ndi BSPT?
A: R (Whitworth) ulusi ndi Rc (Whitworth Pipe) ulusi onse ndi ulusi wofanana, wofanana ndi ulusi wa BSPP.Komabe, ulusi wa R umakhala ndi mizu yozungulira komanso yozungulira, pomwe ulusi wa Rc umakhala ndi mizu yosalala komanso yozungulira.Ulusi wa BSPP ndi BSPT uli ndi mawonekedwe osiyana a ulusi ndipo sagwirizana mwachindunji ndi R ndi Rc ulusi.
Q: Kodi pali malangizo aliwonse okhazikika posankha mtundu woyenera wa ulusi?
Yankho: Inde, pali malangizo okhazikika posankha mtundu woyenera wa ulusi.Malangizowa amaganizira zinthu monga kagwiritsidwe ntchito, kuchuluka kwa kukakamizidwa, komanso kugwirizana ndi zigawo zina.Kufunsira miyezo yamakampani ndi mafotokozedwe kungathandize kudziwa mtundu woyenera wa ulusi.
