Kusiyana kwa Ulusi wa BSPP ndi BSPT: Buku Lotsogolera la Miyezo Yolumikizirana ndi Mafakitale
Kusiyana kwa Ulusi wa BSPP ndi BSPT: Buku Lotsogolera la Miyezo Yolumikizirana ndi Mafakitale
Mu mapaipi a mafakitale ndi makina a hydraulic, ulusi wa BSPP ndi ulusi wa BSPT ndi njira ziwiri zodziwika bwino zolumikizira mapaipi ku Britain zomwe zimagwiritsidwa ntchito kwambiri polumikizirana kotsekedwa padziko lonse lapansi. Ngakhale kuti mayina awo ndi ofanana, ali ndi kusiyana kwakukulu pa kapangidwe kake, mfundo zotsekera.PLndi zochitika zogwiritsira ntchito. Nkhaniyi ikupereka kusanthula kwakuya kwa kusiyana kwa BSPP BSPT kuti ithandize mainjiniya ndi akatswiri kusankha ndi kugwiritsa ntchito moyenera.
Chitsanzo: Kuyerekeza kapangidwe ka ulusi wa BSPP (parallel) ndi BSPT (tapered)
1. Matanthauzo Oyambira
Ulusi wa BSPP (British Standard Pipe Parallel): Uli ndi ngodya ya ulusi wa 55° yokhala ndi ma crests ozungulira ndi mizu. Ulusiwo ndi wozungulira popanda kufooka.
Ulusi wa BSPT (British Standard Pipe Tapered): Ulinso ndi ngodya ya ulusi wa 55° koma uli ndi 1:16 taper (pafupifupi 3/4 mm m'mimba mwake pa inchi iliyonse).
2. Kuyerekeza Kusiyana Kofunika Kwambiri
| Khalidwe | BSPP (Ulusi Wofanana) | BSPT (Ulusi Wopindika) |
| Fomu ya Ulusi | Yozungulira, yopanda kupotoka | Wochepa, 1:16 wochepa |
| Njira Yotsekera | Imafuna makina ochapira kapena mphete ya O | Zimatseka kudzera mu kusokoneza ulusi |
| Kusankhidwa kwa Ulusi | Kawirikawiri amalembedwa kuti "G" (monga, G1/2) | Kawirikawiri amalembedwa kuti "R" (monga, R1/2) |
| Mapulogalamu Ofala | Machitidwe a hydraulic, kutseka kotsika kwa kuthamanga | Kupanikizika kwambiri mapaipis, mizere ya gasi |
| Zofunikira pa Msonkhano | Zofunikira zina zotsekera | Kawirikawiri imafuna tepi yomatira kapena ulusi |
3.Njira Zotsekera Zafotokozedwa
Ulusi wa BSPP supereka mphamvu yotsekera ndipo umafunikira zinthu zina zowonjezera monga mawaya osalala, mawaya omangiriridwa, kapena mphete za O pamaso pa ulusi. Makonzedwe wamba amaphatikizapo "ulusi wa BSPP wokhala ndi chisindikizo cha O-ring".
Ulusi wa BSPT umatseka pang'onopang'ono kudzera mu kulimbitsa pang'onopang'ono kapangidwe kochepetsedwa. Pamene ulusi wamwamuna ndi wamkazi ukugwirana, chotchinga chimapanga kukanikiza kwa radial komwe, kuphatikiza ndi zinthu zotsekera (monga tepi ya ulusi kapena chotsekera cha chitoliro), kumapereka kutseka kodalirika.
4.Malangizo Ogwiritsira Ntchito
Sankhani BSPP pamene: Mukugwira ntchito ndi makina a hydraulic, maulumikizidwe a zida, malo olumikizirana omwe nthawi zambiri amasweka, kapena makina otsika mphamvu omwe amafuna kutsekedwa kodalirika.
Sankhani BSPT pamene: Kuyika mapaipi amadzimadzi kapena a gasi amphamvu, malo okhazikika kapena osakhalitsa, kapena pamene malo ochepa amalepheretsa kugwiritsa ntchito makina ochapira.
Malangizo Achangu: Kuzindikira ndi Kusankha
①Kuyang'ana Kowoneka: Ulusi wa BSPT umawonetsa kusiyana kooneka bwino kwa m'mimba mwake kuchokera kumapeto ena kupita kwina, pomwe ulusi wa BSPP umasunga m'mimba mwake mofanana.
②Kutsimikizira Muyeso: Gwiritsani ntchito zida zoyezera ulusi kuti muyese dayamita pamalo osiyanasiyana kuti muzindikire kuchepa kwa ulusi.
③Kuyang'ana Zizindikiro: Yang'anani zizindikiro za ulusi - Mndandanda wa G umasonyeza BSPP, mndandanda wa R umasonyeza BSPT.
④Chofunika Kwambiri pa Ntchito: Ganizirani kuthamanga kwa makina, mtundu wapakati, ndi kuchuluka kwa kuchotsedwa komwe kumafunika.
Kumvetsetsa kusiyana pakati pa ulusi wa BSPP BSPT kumathandiza kupewa mavuto obwera chifukwa cha zolakwika zoyika ndikuwonjezera kudalirika kwa makina. Mu ntchito zenizeni, mitundu iwiriyi ya ulusi siisinthana mwachindunji ndipo imafuna zigawo zofanana ndi njira zoyenera zotsekera.
