I-High-Pressure Test Coupling 630 Bar ye-Hydraulic Systems

I-ISO 15171 iyahambisana. Isilinganiso sokucindezela esingavuziyo, ukusampula okuwuketshezi, nokufaka umoya wesekethe kufika kumabha angu-630. Osayizi bentambo abalungisekayo, izinto zokuvala, nezinsimbi zomzimba.

Iyini i-Hydraulic Test Coupling?

I-hydraulic test coupling (ebuye ibizwe ngokuthi i  -diagnostic coupling  noma  iphoyinti lokuhlola ) i-compact fitting efakwe ngqo kumjikelezo we-hydraulic. Ihlinzeka ngembobo yokufinyelela esezingeni lapho ungaxhuma khona isikali somfutho, ipayipi lokuhlola, noma isampula yophenyo ngamasekhondi — akukho ukuvala shaqa, akukho ukunqanyulwa komugqa, akukho ukulahlekelwa uketshezi.

Isigxivizo sangaphakathi sesitayela se-poppet sihlala sivaliwe kuze kube yilapho isiphetho sepayipi lokuhlola ukukhwelana siliphusha livuleke. Lo mklamo  ongavuziyo  usho ukuchitheka okungu-zero phakathi kwakho kokubili ukuxhuma nokunqanyulwa, ngisho nasezingcindezini ezisondela emkhawulweni olinganiselwe.

I-ISO 15171:  Lokhu kuhlangana kokuhlola kuthobela  i-ISO 15171-1  (ubukhulu kanye nezidingo zokusebenza zamaphoyinti okuhlola oku-screw-in) kanye ne  -ISO 15171-2  (ukufakwa kokuphela kwepayipi lokuhlola ukuhlangana). Leli zinga lamazwe ngamazwe liqinisekisa ukushintshashintsha kobukhulu kubo bonke abakhiqizi - ipayipi elifanayo lokuhlola lilingana nama-couplings asuka ku-Parker, Stauff, Hydac, Minimess, nabanye.

Izimo ezijwayelekile zokusetshenziswa:

• Ukuhlola amasheke  - Qinisekisa ingcindezi yesistimu ngesikhathi sokuqalisa

• Ukuqapha okujwayelekile  - Ukuhlola indawo ngokushesha ngaphandle kokuphazamisa ukukhiqizwa

• Isampula ye-Fluid  - Khipha amasampula kawoyela ukuze uhlaziye ukungcola

• Ukungenisa umoya  - Khipha umoya ovaleleke ngemva kokulungiswa

• Ukuxazulula inkinga  - Thola ukudida kwengcindezi ngesikhathi sangempela

Imininingwane Ebalulekile

I-Port Connection kanye ne-Seal Mechanism

Lesi sigaba sikhuluma ngezinqumo ezimbili ezibucayi kakhulu zobunjiniyela: ukuthi ukuhlanganisa kuxhuma kanjani kusekethe yakho, nokuthi yini ekugcina kuvaliwe ngaphansi kwengcindezi.

Izinketho Zosayizi Womucu

Izikulufu ezihlanganisayo zizifaka ngqo embobeni ethenjiwe ku-hydraulic manifold yakho, isilinda, noma ibhulokhi yevalvu. Qondanisa intambo nembobo ekhona - imicu engafani ibangela ukuvuza futhi kulimaze zombili izingxenye.

I-M16x2  iwusayizi owodwa ovame uku-oda wezinhlelo zokusebenza ezijwayelekile zezimboni.  I-G1/4  kanye ne  -G1/2  ibusa ezifundeni lapho ukuxhuma kwe-BSP kuyinto evamile (UK, Commonwealth, izitshalo ezindala zase-Europe).

I-Internal Seal Mechanism

Ukusebenza okungavuzi kuncike ku-valve ye-poppet eyenziwe ngokunemba ngaphakathi komzimba ohlanganisayo:

1. Ekuphumuleni  - I-poppet elayishwe entwasahlobo ivala isihlalo sangaphakathi. Ukucindezela kwesistimu kubamba i-poppet ivaleke kakhudlwana.

2. Ukuxhuma  - Ipayipi lokuhlola lokukhwelana (ngokwe-ISO 15171-2) licindezela i-poppet, livule iphaseji kugeji yakho noma isampula. Isigxivizo phakathi kokuphela kwepayipi kanye ne-coupling bore kuvimbela ukuvuza kwangaphandle.

3. Ukunqamula  - Uma ukuphela kwepayipi kuhoxa, amandla entwasahlobo avala i-poppet ngokushesha. Uwoyela oyinsalela echwebeni uhlala ngaphakathi - i-zero drip.

Inhlanganisela yophawu (i-NBR, i-FKM, i-EPDM, noma izinga lokushisa eliphansi) yakha umgoqo oyinhloko phakathi kwe-poppet nesihlalo, kanye nomgoqo wesibili phakathi kwe-hose end taper kanye nebhore yangaphakathi yokuhlanganisa. Ukukhetha impahla yophawu olulungile lokushisa kwakho uketshezi kanye chemistry imbozwe umhlahlandlela wokukhetha  ngezansi.

Kungani Khetha Lezi Couplings Zokuhlola Amabha angama-630?

Ibha ye-630 - Umkhawulo Ohloliwe, Hhayi Ukuthengisa

Ibha engu-630 (9,135 psi) ingcindezi yokusebenza eqinisekisiwe ngokwezivumelwano zokuhlola ze-ISO 15171-1. Ukulungiselelwa ngakunye kuthola ukuhlolwa kwengcindezi yomjikelezo kanye nokuqinisekiswa kokulayisha kobufakazi ngaphambi kokukhululwa kusitoko.

Izinto Ezine Zophawu, Amawindi Amane Asebenzayo

Amasistimu e-hydraulic ahlukene asebenzisa uketshezi oluhlukene emazingeni okushisa ahlukene. Inhlanganisela yophawu olulodwa ayikwazi ukumboza zonke izimo:

• I-NBR (ikhodi N)  — Uketshezi olusebenza nge-mineral-oil hydraulic olufika ku-100 °C. Okuzenzakalelayo okunezindleko eziphansi ~70% wezinhlelo zokusebenza zezimboni.
