Khoom nta
1. Kev sib kis ntawm tus kiv cua suav nrog A B. C, D plaub yam: No2.8 ~ 5 txais A-hom kis tau tus mob, No6 muaj ob hom A thiab C-hom kis, thiab No8-12 siv C Muaj ob hom kev sib kis ntawm hom D, Tsis muaj 16-20 adopts B-hom kis tau tus mob;
2. Cov kiv cua cua tau suav nrog 2.8A-6A feem ntau muaj cov impeller, casing, cua nkag, lub cev muaj zog, thiab lwm qhov chaw, No6C thiab No. 8-20 tsis tsuas yog muaj cov qauv saum toj no, tab sis kuj muaj ib feem kis tau tus mob;
3. Impeller: muaj li ntawm 10 rear tilting tshuab airfoil hniav, nkhaus log npog, thiab flat rear discs, ua los ntawm steel phaj los yog cam khwb cia txhuas alloy. Tom qab dynamic thiab static tshuav nyiaj li cas kho thiab overspeed ua hauj lwm thwmsim, nws muaj high efficiency, du thiab txhim khu kev qha ua haujlwm, thiab huab cua ua haujlwm zoo;
4. Tsev: Ua nyob rau hauv ob hom sib txawv, ntawm cov: No 2.8 ~ 12 casings yog ua tag nrho thiab tsis tuaj yeem disassembled. Lub No16 ~ 20 casing yog ua rau peb hom qhib, uas yog muab faib horizontally rau hauv ob halves. Lub sab sauv ib nrab yog vertically muab faib ua ob halves nyob rau hauv lub centerline thiab txuas nrog bolts rau yooj yim ntxig los yog tshem tawm ntawm lub impeller thaum lub sij hawm installation thiab txij nkawm;
5. Cua nkag: Ua kom tiav cov qauv thiab nruab rau sab ntawm lub kiv cua, nrog ib tug nkhaus seem parallel mus rau axis, txoj haujlwm yog tso cai rau cov cua nkag mus rau hauv lub impeller nrog tsawg tsawg;
6. Kev sib kis: tsim los ntawm spindle, bearing box, dov bearings, pulley los yog coupling;
7. Hlau yeeb nkab lossis cable thaiv, nrog hauv av screws sab hauv thiab sab nraud lub cev muaj zog casing;
Siv tau Scope
1. Nws muaj feem xyuam rau cov chaw hauv Zone 1 thiab Zone 2 ntawm tawg gas ib puag ncig;
2. Nws muaj feem xyuam rau cov chaw hauv Zone 21 thiab 22 ntawm hmoov av combustible ib puag ncig;
3. Haum rau IIA, IIB thiab IIC explosive gas ib puag ncig;
4. Muaj feem xyuam rau T1-T4 kub pab pawg;
5. Nws yog dav siv hauv roj refining, tshuaj, textile, chaw nres tsheb roj thiab lwm qhov chaw txaus ntshai, offshore roj platforms, roj tankers thiab lwm qhov chaw;
6. Sab hauv thiab sab nraum zoov.
