Mau oyamba a Liner & Nut pa Zosakaniza za Ferrule za American-style (Eaton Standard NB200 & NB300)

1. Basic Tanthauzo & Ntchito

Eaton Standard NB200 / NB300 ndi zigawo zikuluzikulu za American JIC 37° Triple-Lok hydraulic tube fittings, zokhala ndi magawano omveka bwino a ntchito kuti atsimikizire kusindikizidwa kokhazikika ndi kulumikizana:

• NB200: Mtedza  - Mutu wa hexagonal wokhala ndi ulusi wamkati, womwe umagwiritsidwa ntchito polimbitsa komanso kukakamiza kuti muteteze msonkhano woyenera.

• NB300: Sleeve / Front Ferrule  - Ferrule yooneka ngati mphete yokhala ndi m'mphepete lakuthwa; ikamangika, imaluma pakhoma la chubu kuti ikwaniritse kusindikiza kodalirika komanso kugwira.

2. NB200 Nut (American JIC Standard)

• Standard : Eaton / Aeroquip, imagwirizana ndi JIC B-1

• Ulusi : UNF ulusi wabwino waku America (mwachitsanzo, 7/16-20, 1/2-20, 9/16-18, etc.)

• zakuthupi : Mpweya wa carbon zitsulo (zinc-yokutidwa / wakuda okusayidi), chitsulo chosapanga dzimbiri 304/316

• Zofunika Kwambiri :

  • Imatumiza torque ndikukakamiza mwamphamvu malaya a NB300

  • Amalumikizana ndi ulusi woyenerera kuti akonze chubu molimba

  • Imaletsa kumasuka komanso kukana kugwedezeka m'malo ovuta kugwira ntchito

• Kukula Kwachidule (Ichi) : Kufananiza kukula kwa machubu a hydraulic chubu, okhala ndi ma code akulu ogwirizana ndi machubu (zatsatanetsatane patebulo lofananira lomwe lili pansipa).

3. NB300 Sleeve (Front Ferrule)

• Muyezo : Eaton Triple-Lok JIC 37°

• Kapangidwe : Chingwe chimodzi chakutsogolo chokhala ndi m'mphepete mwamkati ndi koni ya 37 ° yakunja (yofanana ndi thupi loyenera la JIC)

• Zakuthupi : Chitsulo cha carbon high, chitsulo chosapanga dzimbiri cholimba (chovala ndi kukana dzimbiri)

• Kusindikiza Mfundo :

  • Kulimbitsa mtedza → kukankhira manja a NB300 patsogolo

  • Kunja kwa 37° koni yokhala ndi koni yoyenerera ya 37° → imapanga kusindikiza kumaso

  • Kuluma kwamkati mkati mwakhoma lakunja la chubu → kumapangitsa kuti pakhale mphamvu ziwiri zakugwira ndi kusindikiza kwa radial

  • Osagwedezeka komanso kupanikizika kwambiri (mpaka pafupifupi 40MPa)

• Lamulo Lofananira : NB300-XX iyenera kufanana ndi NB200-XX yofanana. Chitsanzo: 1/4' chubu → NB200-04 Mtedza + NB300-04 Sleeve

4. Size Matching Table (NB200 & NB300)

5. Zina za American JIC Triple-Lok Fittings (vs. Metric 24° Cone)

6. Zolemba Zosankha & Kuyika

6.1 Malangizo Osankha

• Kufananiza Kukula: Ma manambala awiri omaliza amitundu ya NB200/NB300 amafanana ndi chubu chakunja kwake (mwachitsanzo, 04 = 1/4', 06 = 3/8').

• Kusankhidwa kwa Zinthu: Chitsulo cha carbon kwa malo ogwirira ntchito; chitsulo chosapanga dzimbiri 304/316 cha malo owononga (mwachitsanzo, panyanja, makampani opanga mankhwala).

6.2 Kuyika Masitepe & Zolemba

1. Konzani chubu: Onetsetsani kuti mapeto a chubu ndi osalala, opanda burr, ndi odulidwa molunjika (palibe bevel).

2. Sonkhanitsani zigawo: Choyamba ikani mtedza wa NB200 pa chubu, kenako tsitsani malaya a NB300 (m'mphepete mwakuyang'ana thupi loyenera).

3. Mangitsani: Limbani natiyo ndi dzanja mpaka itakhudza thupi loyenera, kenaka gwiritsani ntchito wrench kutembenuza 1 mpaka 1¼ (kusintha molingana ndi kukula kwa chubu).

4. Yang'anani: Mukayika, onetsetsani kuti manjawo alumidwa ndi khoma la chubu ndipo palibe kutayikira pansi pa kukanidwa.
