Khuluma ngobudlelwano obunxantathu phakathi kwengcindezi yamagama, ingcindezi yokuklama kanye nengcindezi yokusebenza

1. Iyini ingcindezi yegama elithi PN (MPa)?

Inani eliyireferensi elihlobene namandla okumelana nokucindezela kwezingxenye zesistimu yamapayipi libhekisela ekwakhiweni kwengcindezi ehlobene namandla omshini wezingxenye zamapayipi.Ukucindezela okulinganiselwe ngokuvamile kuvezwa yi-PN.

(1) Ukucindezela okuzisholo - amandla okucindezela omkhiqizo ezingeni lokushisa eliyinkomba, elivezwe nge-PN, iyunithi: I-MPa.

(2) Izinga lokushisa eliyinkomba: Izinto ezihlukene zinezithenjwa ezihlukene zokushisa.Isibonelo, izinga lokushisa eliyinkomba lensimbi lingama-250°C

(3) Ukucindezela okulinganiselwe okungu-1.0Mpa, okuchazwa ngokuthi: PN 1.0 Mpa

2. Kuyini ukucindezeleka emsebenzini?

Kubhekiselwa kumfutho omkhulu oshiwo ngokwezinga lokushisa eliphezulu lokusebenza kwepayipi elidluliswa phakathi kuwo wonke amazinga ukuze kuphephe uhlelo lwamapayipi.Ukucindezela kokusebenza kuvame ukuvezwa ku-Pt.

3. Iyini ingcindezi yokuklama?

Isho ingcindezi enkulu esheshayo yesistimu yepayipi lokuphakela amanzi esebenza odongeni lwangaphakathi lwepayipi.Ngokuvamile, isamba sokucindezela kokusebenza kanye nokucindezela kwesando samanzi okusala kuyasetshenziswa.Ukucindezela kokuklama kuvame ukuvezwa ku-Pe.

4. Ingcindezi yokuhlola

Ingcindezi okufanele kufinyelelwe kuyo icaciswe ukuze kuhlolwe amandla acindezelayo kanye nokuqina komoya kwamapayipi, iziqukathi noma izinto zokusebenza.Ukucindezela kokuhlola kuvame ukuvezwa kuHu.

5. Ubudlelwano phakathi kwengcindezi yamagama, ingcindezi yokusebenza kanye nengcindezi yokuklama

Ukucindezela okuzisholo kuwukucindezela okuzisholo okucaciswe ngokuzenzakalelayo ukuze kube lula ukuklama, ukukhiqiza nokusetshenziswa.Iyunithi yalokhu kucindezela okujwayelekile kuwukucindezela, futhi ukucindezela kuyigama elivamile ngesiShayina, futhi iyunithi ithi “Pa” esikhundleni sika-“N”.Ingcindezi yamagama ngesiNgisi ithi pres-surenomina: l egameni noma ngesimo kodwa hhayi eqinisweni (igama, igama).Ukucindezela okulinganiselwe komkhumbi wokucindezela kubhekisela ekucindezelweni okujwayelekile kwe-flange yomkhumbi wokucindezela.Ukucindezela okulinganiselwe kwe-flange yomkhumbi wengcindezi ngokuvamile kuhlukaniswa ngamamaki angu-7, okungukuthi 0.25, 0.60, 1.00, 1.60, 2.50, 4.00, 6.40MPa.Ingcindezi yokuklama=1.5×ingcindezi yokusebenza.

Ingcindezi yokusebenza itholakala ekubalweni kwe-hydraulic yenethiwekhi yamapayipi.

6. Ubudlelwano

Ingcindezi yokuhlola>ingcindezi yokuzisholo>ingcindezi yokuklama>ingcindezi yokusebenza

Ingcindezi yokuklama = 1.5 × ingcindezi yokusebenza (imvamisa)
