Chifukwa chiyani mungasankhe ma valve a mpira

1. Yosavuta kugwiritsa ntchito komanso yotsegula ndi kutseka mwachangu.

Ingotembenuzani chogwirira kapena choyendetsera ndi madigiri 90 (kotala la kutembenuka) kuti musinthe kuchoka pa kutseguka kwathunthu kupita ku kutsekedwa kwathunthu kapena mosemphanitsa. Izi zimapangitsa kuti kutsegula ndi kutseka kukhale kosavuta komanso mwachangu, ndipo ndikoyenera makamaka pazochitika zomwe kutsegulidwa ndi kutsekedwa pafupipafupi kapena kutsekedwa mwadzidzidzi kumafunika.

2. Kugwira ntchito bwino kwambiri posindikiza

Mpirawo ukatsekedwa bwino, umalumikizana mwamphamvu ndi mpando wa valavu, zomwe zimapangitsa kuti ukhale wotseka mbali zonse ziwiri (ungatseke mosasamala kanthu kuti mbali yanji yomwe imachokera), zomwe zimathandiza kuti utuluke. Ma valavu apamwamba kwambiri (monga omwe ali ndi zisindikizo zofewa) amatha kutayikiratu, kukwaniritsa miyezo yoteteza chilengedwe komanso chitetezo.

3. Ili ndi mphamvu yochepa kwambiri yolimbana ndi madzi komanso mphamvu yolimba yoyendera madzi.

Vavu ikatsegulidwa bwino, kukula kwa njira mkati mwa thupi la valavu nthawi zambiri kumakhala kofanana ndi kukula kwa mkati mwa chitoliro (chomwe chimatchedwa valavu ya mpira wonse), ndipo njira ya mpira imakhala yolunjika. Izi zimathandiza kuti njirayo idutse popanda chopinga, yokhala ndi mphamvu yochepa kwambiri yolimbana ndi madzi, kuchepetsa kutayika kwa mphamvu ndikusunga mphamvu zomwe mapampu kapena ma compressor amagwiritsa ntchito.

4. Kapangidwe kakang'ono komanso kamene kali ndi voliyumu yochepa

Poyerekeza ndi ma valve a chipata kapena ma valve ozungulira okhala ndi mulifupi womwewo, ma valve a mpira ali ndi kapangidwe kosavuta komanso kocheperako komanso ndi opepuka kulemera. Izi zimasunga malo oyikapo ndipo ndizothandiza makamaka pamakina a mapaipi omwe ali ndi malo ochepa.

5. Ntchito zosiyanasiyana komanso kusinthasintha kwamphamvu

• Kusinthasintha kwa zofalitsa:Itha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga madzi, mafuta, gasi, nthunzi, mankhwala owononga (zipangizo zofanana ndi zisindikizo ziyenera kusankhidwa).
• Kuthamanga ndi kutentha:Kuyambira pa vacuum mpaka pa high pressure (mpaka mazana angapo a Bar), kuyambira pa kutentha kochepa mpaka kutentha kwapakati-kwapamwamba (kutengera ndi zinthu zotsekera, zotsekera zofewa nthawi zambiri zimakhala ≤ 200℃, pomwe zotsekera zolimba zimatha kufika kutentha kwakukulu). Izi zimagwira ntchito pamitundu yonseyi.
• Makulidwe a m'mimba mwake:Kuyambira ma valve ang'onoang'ono a zida (mamilimita ochepa) mpaka ma valve akuluakulu a mapaipi (opitirira mita imodzi), pali zinthu zokhwima zomwe zikupezeka zamitundu yonse.
