• Kwa makina a hydraulic pamagalimoto, makina opangira magalimoto, makina aulimi, mafakitale ndi zida zina;
• Zida zopangira mafuta (zopopera mafuta ndi mafuta, kupereka mafuta kwa ogula, etc.).
Pomaliza, mapaipi amagawidwa m'mitundu iwiri pokhudzana ndi magetsi osasunthika:
• Mipaipi yokhazikika;
• Mapaipi apansi opatutsira magetsi osasunthika.
Popanga ma hoses amtundu wachiwiri, mzere wamkuwa umaperekedwa, womwe umagwira ntchito yokhazikika.Izi MBS mapaipi ntchito pa refueling makina ndi zipangizo, pa zipangizo mafakitale, etc.
Mwa mawonekedwe a zotchinga za SBS, ziyenera kudziwidwa:
• Kuthamanga kwa ntchito - kwa kuyamwa - 0.09 MPa (0.9 atmospheres), kutulutsa - mlingo woyenera wa 0.1, 0.16, 0.25, 0.4, 0.63, 1.0, 1.6, 2.5, 4, 6.3 ndi 10 MPa (kuchokera ku 0 mpaka 10) ;
• M'kati mwake - kuchokera 3 mpaka 25 mm (PVC hoses) ndi 4 mpaka 100 mm (mapaipi a rabara);
• M'mimba mwake kunja - zimadalira makulidwe a makoma, mtundu wa kuluka, kukhalapo kwa kulimbikitsana, etc. Monga lamulo, m'mimba mwake ndi 1.5-3 nthawi zazikulu kuposa zamkati;
• Kutentha kwa ntchito.
Payokha, ziyenera kunenedwa za parameter yomaliza.Masiku ano, ma hoses a MBS amapangidwa m'madera atatu a nyengo, amasiyana ndi kutentha kosavomerezeka kovomerezeka:
• Kwa nyengo yozizira - mpaka -35 ° C;
• Kwa nyengo zotentha - mpaka -20 ° C;
• Kwa nyengo yozizira - mpaka -50 ° C.
Kutentha kwabwino kwa ma hoses onse ndi chimodzimodzi - mpaka + 70 ° C pamafuta (mafuta, palafini, mafuta a dizilo) mpaka + 100 ° C pamafuta.
Kupanga payipi ya MBS
PVC mapaipi (machubu) amakonzedwa mosavuta.Muzosavuta, iyi ndi payipi, m'makoma omwe muli nsalu kapena waya.Palinso mitundu ingapo yamachubu a PVC - ali ndi wosanjikiza wamkati womwe umalimbana kwambiri ndi mafuta, mafuta ndi zakumwa zina.Kulimbitsa kumatha kukhala mumzere wakunja kapena pakati pa zigawo.
Ma hoses a rabara ndi mapangidwe amagawidwa m'magulu angapo:
• Zosalimbikitsidwa ndi kulimbikitsa ulusi (GOST 10362-76);
• Zosalimbikitsidwa ndi ulusi / nsalu zowonjezera ndi chimango cha nsalu (GOST 18698-79);
• Kulimbikitsidwa kwa mitundu yofanana (GOST 5398-76).
Ma hoses osalimbikitsidwa okhala ndi ulusi wolimbitsa ulusi amakonzedwa mophweka, ndi mawonekedwe a magawo atatu:
Kapangidwe ka payipi yolimba ya rabara MBS
1.Zosanjikiza zamkati ndi mphira womwe umalimbana ndi mafuta, mafuta ndi zakumwa zina;
2.Thread / textile reinforcement - kuluka kopangidwa ndi kupanga, thonje kapena ulusi wophatikizika / nsalu, zitha kuchitidwa mu zigawo 1-6;
3.Kusanjikiza kwakunja ndi rabara yomwe imalimbana ndi zoyipa zachilengedwe, mafuta ndi mafuta, mankhwala osiyanasiyana, ndi zina.
Ma hoses okhala ndi chimango chansalu amakhala ndi chowonjezera chakunja - nsalu yoluka yopangidwa ndi nsalu, thonje kapena kuphatikiza.Chimangocho chimavula pa payipi mumagulu angapo.Nthawi zambiri mtundu uwu wa mankhwala amatchedwa durite kapena hoses ndi durite kuluka.
M'mapaipi olimbikitsidwa, mphira wapakati amawonjezeredwa, momwe chitsulo kapena waya wamkuwa (malinga ndi miyezo yapakhomo) kapena zitsulo zopyapyala zimayikidwa.Kulimbitsa kumatha kukhala ndi gawo limodzi kapena awiri, koma pali manja apadera okhala ndi kulimbikitsidwa kwamagawo angapo.Mzere wamkuwa ukhoza kukhala mumtundu womwewo wa payipi.
Mitundu ina ya mapaipi a rabara amakhala ndi zomangira kumapeto mbali imodzi kapena mbali zonse.Ma hoses oterowo, monga lamulo, amapangidwa kuti aziyika mu zigawo zina, misonkhano ndi machitidwe a magalimoto ndi zipangizo zina, amadulidwa kukula kwake ndikukhala ndi makhalidwe oyenera.
Makhalidwe, mayina ndi kupanga ma hoses a rabara a MBS amayendetsedwa ndi zomwe zili pamwambapa ndi zina.Ma hoses ofanana a PVC alibe muyezo umodzi, amapangidwa motsatira mafotokozedwe osiyanasiyana.
Nkhani zakusankha ndikugwiritsa ntchito ma hoses a MBS
Mitundu yosiyanasiyana yamafuta osamva mafuta
Posankha ma hoses osamva mafuta, ndikofunikira kuganizira cholinga chawo chamtsogolo komanso momwe zinthuzi zidzagwiritsire ntchito.
Kuti mugwiritse ntchito payekha pofuna kupopera mafuta kapena mafuta, payipi yotsika mtengo ya PVC ndiyokwanira - ndi yopepuka, yosavuta kusunga komanso yosavuta kugwiritsa ntchito (makoma owonekera amakulolani kudziwa kupezeka kwa madzimadzi, etc.).
Pakukonza mafuta, mafuta, braking ndi machitidwe ena omwe kupanikizika kowonjezereka kwa sing'anga yogwirira ntchito kumasungidwa, payipi ya rabara ya MBS iyenera kugwiritsidwa ntchito.Pogula, m'pofunika kusankha m'mimba mwake yoyenera ndi makhalidwe - ntchito kuthamanga ndi kutentha osiyanasiyana.Pankhaniyi, m'pofunikanso kusamalira zomangira ndi mapeto zoikamo kukwera payipi.
Nthawi zambiri, pokonzanso machitidwe, zida ndi misonkhano, ma hoses okhala ndi zida zomangika kale amagulitsidwa - iyi ndiye njira yabwino kwambiri yomwe imapulumutsa nthawi ndi ndalama (popeza palibe chifukwa chodula payipi mpaka kutalika ndikuyika zoikamo), ndi imapereka kudalirika kwakukulu kwadongosolo.
Pamafakitale ndi ntchito zina zapadera, ndikofunikira kusankha ma hoses a MBS okhala ndi mawonekedwe ena, kuphatikiza kuthekera kwapansi, zinthu zazikuluzikulu, ma hoses amtundu wina wamadzimadzi, ndi zina zambiri.
Zomaliza za hoses za MBS
Kuti mupange chisankho choyenera cha hose, muyenera kulabadira chizindikiro chake.Mogwirizana ndi miyezo, chizindikirocho chimaphatikizapo chisonyezero cha mkati ndi kunja kwake, kuthamanga kwa ntchito, kusintha kwa nyengo ndi GOST, zomwe zimagwirizana ndi mankhwalawa.Mwachitsanzo, chizindikiro "Hose 20x30-1 GOST 10362-76" zikutanthauza kuti payipi ali ndi m'mimba mwake mkati 20 mm, m'mimba mwake 30 mm, kuthamanga ntchito 1 MPa ndipo lakonzedwa kuti azigwira ntchito m'madera otentha ndi otentha. .Kukhalapo kwa zilembo "HL" kumasonyeza kuthekera kwa ntchito payipi mu nyengo yozizira.Mapaipi osamva mafuta ndi mafuta molingana ndi GOST 18698-79 amalembedwa ndi mtundu wa "Sleeve B (I) -10-50-64-T" - pomwe "B (I)" amatanthauza kugwiritsidwa ntchito kwa mankhwalawa. kugwira ntchito ndi mafuta ndi mafuta, chiwerengero choyamba ndi kuthamanga kwa ntchito m'mlengalenga, manambala awiri otsiriza ndi ma diameter amkati ndi akunja, kalata yomaliza ndi kusintha kwa nyengo ("T" - kwa nyengo yotentha, "U" - yotentha. , "HL" - ozizira).Hoses malinga ndi GOST 5398-76 ali ndi chizindikiro chofanana cha mtundu wa "Hose B-2-25-10 GOST 5398-76", kumene "B-2" ndi kugwiritsidwa ntchito kwa mankhwala pogwiritsira ntchito mafuta ndi mafuta, "25 " ndi m'mimba mwake (m'mimba mwake wakunja sikuwonetsedwa), ndipo 10 ndi mphamvu yogwira ntchito mumlengalenga.Zimasonyezanso nyengo ya nyengo (kwa nyengo yotentha - osati chizindikiro, kwa otentha - "T", ozizira - "HL").
Podziwa izi, mutha kusankha mosavuta payipi yofunikira, ndikuthetsa ntchitozo molimba mtima.
