FAQ
Q: Koj yuav ua li cas tiv thaiv cov ncej nplawm thiab kev co ntau dhau hauv cov twj tso kua mis nrog qhov tob tob tshaj 15 meters?
A: Kev ruaj ntseg ncej yog khaws cia los ntawm kev xam qhov tseem ceeb ntawm qhov nrawm nrawm thiab tso lub tes tsho nruab nrab ntawm lub sijhawm ntsuas (feem ntau txhua txhua 1.5 txog 2.0 meters). Tsis tas li ntawd, cov kab shafts tau ua ke nrog kev ua kom zoo- ua lub tes tsho nruj couplings, thiab cov kav dej kem yog tsim los nrog cov phab ntsa hnyav kom tiv thaiv hydraulic thrust yam tsis muaj cov qauv flexing.
Q: Dab tsi yog qhov txawv ntawm cov khoom-lubricated thiab kaw kab ncej bearings?
A: Khoom-lubricated bearings siv lub twj tso kua mis nws tus kheej los lubricate roj hmab los yog ceramic kab ncej bearings, uas yog tus nqi - zoo rau kev siv dej huv. Cov kab sib txuas ntawm cov kabmob muaj nyob hauv ib lub raj tiv thaiv cais tawm nrog cov dej huv lossis cov roj, ua rau nws yuav tsum tau ua thaum tuav cov khoom abrasive, xuab zeb, lossis cov kua tshuaj lom neeg uas yuav ua rau cov kabmob ua ntej ntxov.
Q: Cov twj no puas tuaj yeem ua cov kua dej abrasive uas muaj cov khib nyiab tshem tawm?
A: Yog lawm, yog tias cov khoom ntim tau tswj tau qis dua 50 ppm thiab tus kheej qhov loj me tsis tshaj 3 hli. Rau abrasive slurries, peb muab lub twj tso kua mis nrog hardened hlau dawb (ASTM A532) los yog duplex stainless hlau impellers, ua ke nrog ib tug sab nraud huv si dej system cais abrasives los ntawm kab ncej bearings thiab seals.
Q: Cov ntaub ntawv tshuaj ntsuam thiab ntawv pov thawj dab tsi tau muab ua ntej xa khoom xa tuaj?
A: Cov ntaub ntawv txheej txheem suav nrog ISO 9906 kev ntsuas kev ua haujlwm nkhaus, daim ntawv pov thawj cov khoom siv (EN 10204 3.1), PMI cov ntawv tshaj tawm, daim ntawv pov thawj ntsuas qhov sib npaug, thiab daim ntawv pov thawj qhov dav dav dav dav (GA) kos duab. Cov ntaub ntawv API 610 tag nrho (cov ntaub ntawv nplooj ntawv, kev vibration spectra, NDE cov ntawv ceeb toom) tau yooj yim rau kev txiav txim petrochemical.
Q: Yuav ua li cas cov kav dej ntev thiab tsav shafts ntim rau thoob ntiaj teb shipping kom tsis txhob muaj kev puas tsuaj rau kev thauj mus los?
A: Cov kav dej thiab cov ncej tsav ntau tshaj qhov ntev ntawm lub thawv ntim tau ntim rau hauv rugged, fumigated ntoo crates muaj zog nrog sab hauv steel eeb thiab bracing. Cov ncej yog coated nrog los tiv thaiv -corrosion preservation roj thiab qhwv nruj nreem nyob rau hauv VCI (Volatile Corrosion Inhibitor) zaj duab xis los tiv thaiv pitting thiab oxidation thaum lub sij hawm maritime thauj.
Q: Dab tsi ntawm qhov chaw teeb tsa cov ntaub ntawv xav tau ua ntej tshaj tawm cov lus hais?
A: Txhawm rau ua kom tiav lub twj tso kua mis qhov loj me thiab cov lej engineering, thov muab cov hauv qab no:
Tag nrho qhov yuav tsum tau ntws tus nqi thiab tag nrho lub taub hau dynamic.
Kev teeb tsa qhov tob los ntawm mounting foundation pem teb mus rau hauv qab ntawm lub sump.
