Qhov sib txawv ntawm cov ntsiab lus ntawm cov tub ntxhais lub luag haujlwm
| Ntaus | Ua haujlwm tseem ceeb | Hauv paus hniav |
|---|---|---|
| Dai | Ib Leeg-Valve Ob Chav Sealing Volution Vais ntawm ob qho kawg ntawm cov raj dej, los ntawm Unvelline, los ntawm Kev Tshaj Tawm Nruab Nrab (txhawm rau tiv thaiv tuav siab) | API 6D QU.4 |
| Pab tsiaj | Ib lub valve nrog dual foob pob sib tw, muab ob npaug rau kev sib khi ua ke thaum kaw (tawm tsam ib sab ntshav siab) | API 6D Cov Lus Txhais Ntxiv |
Intrinsic distintion:
DBB tsom rau Bi-Directional siab txiav-tawm thiab nyem kev nyab xeeb;
Dib tsom rau redundant muaj ntawm ib qho siab.
Cov qauv rooj zaum thiab tshuab sib khi
1. Lub rooj teeb tsa
DBB:
Ob chav Spe Spe Valve Lub Rooj (Ib Leeg Piston nyhuv, Unidirectional sealing);
Nruab nrab siab thawb lub rooj zaum kom nias lub pob kom ua tiav kev sib khi.
Dib: Muaj ob hom sub:
DIB-1: Ob chav DPE valve lub rooj (ob chav piston nyhuv, bidirectional sealing);
Dib-2: SPE + DPE valve lub rooj sib xyaw ua ke (hybrid foob).
2. Siab Kev Ntsig Cov yam ntxwv
| Ntaus | Nruab nrab kab noj hniav siab nyem mechanism | Qhov Xav Tau Rau Txoj Kev Pab Ntaus |
|---|---|---|
| Dai | Tsis siv neeg tso tawm rau cov raj xa dej nyob rau hauv cov ntaub ntawv ntawm kev tsis txaus ntseeg siab (cia siab rau spe rooj siv) | Tsis yog-yuav tsum tau ua |
| Dib-1 | Sab Nraud Kev Siv Hluav Taws Xob (Ob Chav DPE DPE tsis yog tus kheej-relieving) | Kev Txhim Kho |
| Dib-2 | Tsis Siv Neeg Siab Tas Rau Spe Sab, DPE Consts Tswj BI-Directional Sealing | Tsis yog-yuav tsum tau (tab sis pom zoo) |
NCO TSEG: SPE (Ib Leeg Piston nyhuv) lub rooj zaum hauv siab nyob rau hauv ib qho kev taw qhia hauv ib qho, dpe (wech piston nyhuv) nyob rau hauv lub siab hauv ob qho kev qhia.
Kev Nyab Xeeb thiab Ntawv Teev Npe
1. Kaw kev cia siab
DBB:
Bi-directional txiav-tawm, tab sis ib qho ntsiab lus ntawm tsis muaj kev pheej hmoo (ib lub valve ib lub valve kwv yees li ntawm kev sib khi);
Haum rau kev tshaj tawm cov xov xwm ceev (xws li roj nkev, cov roj ua kom zoo).
Dib:
Muab ob npaug rau kev sib khi ywj siab, kev tsim qauv qub los txo qhov kev pheej hmoo ntawm to.
Haum rau kev pheej hmoo siab (sulphur-muaj roj thiab roj, tshuaj lom cov tshuaj).
2. Cov ntawv thov raug
| Ntaus | Siv tau ua haujlwm | Kev Lag Luam Kev Lag Luam |
|---|---|---|
| Dai | Nruab Nrab thiab tsis tshua muaj siab siv siab (Chav Kawm 150 ~ 600), nyem siab hauv nruab nrab Chamber yog xav tau. | Cov Khoom Roj Pipeline |
| Dib-1 | Kev siab siab Sulfur tej yam kev mob, yuav tsum tau ua hluav taws kev nyab xeeb | Kev rho tawm cov qub rau cov nroj tsuag roj kho |
| Dib-2 | Kev lag luam nruab nrab-ua haujlwm xav tau qhov sib npaug ntawm kev lag luam thiab kev nyab xeeb | Ntawv Sau Cov Khaub Ncaws Hnav |
Kev Xaiv Xaiv
DBB txwv:
Tsis tuaj yeem hloov ob-lub cev sib cais (ib lub pob hluav taws xob txiav tsuas yog muaj);
Media muaj cov khoom seem muaj khoom yuav ua rau nqaj hlau valve jamming.
Dib zoo:
Dib-1 yog qhov haum rau xoom kom ua haujlwm hnyav (piv txwv li cov nkoj hiav txwv tob);
Dib-2 cov nyiaj tshuav nqi thiab kev nyab xeeb.
Tuav cov lus qhia: Dib li qub yuav tsum tau muab ntsia hauv txoj kev taw qhia (lub rooj zaum ntawm Dib-2 yuav tsum tau ntsib lub siab tau).
Ntsiab lus:
DBB=bi-directional txiav-tawm + tus kheej vering → kev daws teeb meem;
Dib =} Dua} Kev sib cais siab dua + Kev sib khi siab Referred rau High-kev pheej hmoo tshaj tawm (faib ua Dib-1 / Dib-2).
Raws li API 6D, kev xaiv yuav tsum ua raws li kev sib xyaw ua ke ntawm kev phom sij nruab nrab, qib siab thiab muaj kev tiv thaiv.
