Kev Kho Txhua Xyoo

Kev ua haujlwm twj tso kua mis yuav tsum tau tshuaj xyuas thiab sau tseg kom meej yam tsawg kawg ib xyoos ib zaug. Lub hauv paus kev ua tau zoo yuav tsum tau tsim ua ntej hauv submersible ntsug turbine twj tso kua mis kev ua haujlwm, thaum cov khoom tseem nyob hauv qhov tam sim no (tsis hnav) thiab tau raug ntsia thiab kho kom zoo. Cov ntaub ntawv hauv qab no yuav tsum muaj xws li:

1. Lub taub hau (qhov sib txawv ntawm qhov sib txawv) ntawm lub twj tso kua mis ntsuas ntawm qhov nqus thiab tawm qhov siab nyob rau hauv peb mus rau tsib qhov kev ua haujlwm yuav tsum tau txais. Kev nyeem ntawv xoom xoom yog qhov siv tau zoo thiab yuav tsum tau suav nrog qhov ua tau thiab siv tau.

2. Pump ntws

3. Lub cev muaj zog tam sim no thiab qhov hluav taws xob sib thooj rau saum toj no peb mus rau tsib lub ntsiab lus ntawm kev ua haujlwm

4. Qhov xwm txheej vibration

5. Cov kabmob lub thawv kub

Thaum ua koj qhov kev ntsuam xyuas txhua xyoo twj tso kua mis, nco ntsoov cov kev hloov pauv hauv lub hauv paus thiab siv cov kev hloov pauv no los txiav txim siab txog qib kev saib xyuas uas yuav tsum tau rov qab lub twj tso kua mis kom ua haujlwm zoo.

Thaum kev tiv thaiv thiab kev tiv thaiv kev tiv thaiv tuaj yeem ua rau kojsubmersible ntsug turbine twj tso kua miskev khiav hauj lwm ntawm kev ua haujlwm siab tshaj plaws, muaj ib qho tseem ceeb uas yuav tsum tau khaws cia hauv siab: tag nrho cov twj tso kua mis yuav ua tsis tiav. Cov kabmob tsis ua haujlwm feem ntau yog tshwm sim los ntawm lubricating media es tsis yog cov khoom siv zog. Tias yog vim li cas kev saib xyuas cov kabmob lubrication (lwm daim ntawv ntawm kev saib xyuas) tuaj yeem pab ua kom muaj lub neej ntev thiab ua kom ntev lub neej ntawm koj lub twj tso kua mis submersible ntsug turbine.

> Thaum xaiv cov roj nplua nyeem, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov roj uas tsis muaj npuas, tsis muaj tshuaj ntxuav tes. Cov roj qib tsim nyog yog nyob rau nruab nrab ntawm tus nyuj lub qhov muag pom iav ntawm sab ntawm cov kabmob vaj tse. Tshaj-lubrication yuav tsum tau zam, vim hais tias tshaj-lubrication tuaj yeem ua rau muaj kev puas tsuaj ntau npaum li cov roj lubrication. 

Cov roj nplua nyeem ntau dhau yuav ua rau lub zog siv zog me ntsis thiab ua kom muaj cua sov ntxiv, uas yuav ua rau cov roj nplua nyeem ua npuas dej. Thaum kuaj xyuas qhov xwm txheej ntawm koj cov roj nplua nyeem, cloudiness yuav qhia tag nrho cov ntsiab lus dej (feem ntau yog qhov tshwm sim ntawm condensation) ntau dua 2,000 ppm. Yog tias qhov no tshwm sim, cov roj yuav tsum tau hloov tam sim ntawd.

Yog hais tias lub twj tso kua mis yog nruab nrog relubricable bearings, tus neeg teb xov tooj yuav tsum tsis txhob sib tov roj ntawm cov khoom sib txawv los yog sib xws. Tus neeg saib xyuas yuav tsum nyob ze rau sab hauv ntawm cov kabmob. Thaum relubricating, xyuas kom cov bearings fittings yog huv si, vim hais tias muaj kev sib kis yuav luv luv lub neej kev pab cuam ntawm bearings. Overlubrication yuav tsum raug zam vim qhov no tuaj yeem ua rau muaj qhov kub thiab txias hauv cheeb tsam hauv cov kabmob sib tw thiab kev loj hlob ntawm agglomerates (khoom). Tom qab rov ua dua, cov bearings yuav khiav ntawm qhov kub thiab txias me ntsis rau ib mus rau ob teev.

Thaum hloov ib lossis ntau qhov ntawm lub twj tso kua mis ua tsis tau, tus neeg teb xov tooj yuav tsum siv sijhawm los tshuaj xyuas lwm qhov ntawm lub twj tso kua mis kom pom tias muaj kev qaug zog, hnav ntau dhau thiab tawg. Nyob rau lub sijhawm no, qhov hnav yuav tsum tau hloov pauv yog tias nws tsis ua raws li cov qauv kev zam tshwj xeeb hauv qab no:

1. Bearing thav duab thiab ko taw - Pom pom qhov tawg, roughness, xeb lossis nplai. Xyuas machined nto rau pitting los yog yaig.

2. Bearing thav duab - Tshawb xyuas cov xov sib txuas rau cov av. Ntxuav thiab ntxuav cov xov yog tias tsim nyog. Tshem tawm / tshem tawm cov khoom xoob lossis txawv teb chaws. Txheeb xyuas cov roj lubrication kom paub tseeb tias lawv muaj tseeb.

3. Shafts thiab bushings - Saib xyuas cov cim ntawm kev hnav hnyav (xws li grooves) lossis pitting. Tshawb xyuas cov kabmob haum thiab cov ncej khiav tawm thiab hloov cov ncej thiab bushing yog hnav lossis siab ntev dua 0.002 ntiv tes.

4. Lub tsev - Pom pom kev kuaj xyuas cov cim ntawm hnav, corrosion lossis pitting. Yog tias qhov hnav qhov tob tshaj 1/8 nti, lub tsev yuav tsum tau hloov. Xyuas lub gasket nto rau cov cim qhia ntawm irregularities.

5. Impeller - Saib xyuas lub impeller rau hnav, yaig lossis corrosion puas. Yog tias cov hniav hnav ntau dua 1/8 nti tob, lossis yog tias cov hniav yog khoov lossis deformed, lub impeller yuav tsum tau hloov.

6. Bearing Frame Adapter - Saib xyuas cov kab nrib pleb, warping lossis corrosion puas thiab hloov yog tias muaj cov xwm txheej no.

7. Bearing vaj tse - Pom pom kev hnav, corrosion, tawg lossis dents. Yog hnav los yog tsis kam, hloov cov kabmob vaj tse.

8. Seal Chamber / Gland - Pom pom qhov tawg, pitting, yaig lossis corrosion, them nyiaj tshwj xeeb rau kev hnav, khawb lossis grooves ntawm lub foob chamber nto. Yog tias hnav ntau dua 1/8 nti tob, nws yuav tsum tau hloov.

9. Ncej - Tshawb xyuas cov ncej kom pom cov cim ntawm corrosion lossis hnav. Txheeb xyuas qhov ncaj ntawm tus ncej thiab nco ntsoov tias qhov siab tshaj plaws tag nrho cov ntsuas ntsuas (TIR, runout) ntawm lub tes tsho foob thiab cov ntawv sib txuas tsis tuaj yeem tshaj 0.002 ntiv tes.

Txawm hais tias kev saib xyuas niaj hnub yuav zoo li daunting, cov txiaj ntsig deb tshaj qhov kev pheej hmoo ntawm kev saib xyuas qeeb. Kev saib xyuas zoo ua kom koj lub twj tso kua mis khiav tau zoo thaum txuas nws lub neej thiab tiv thaiv lub twj tso kua mis ntxov ntxov. Tawm hauv kev saib xyuas tsis tu ncua, lossis muab tso rau ntev dua, tuaj yeem ua rau muaj kev poob qis thiab raug nqi kho. Txawm hais tias nws yuav tsum tau ua tib zoo saib xyuas kom meej thiab ntau cov kauj ruam, muaj kev npaj kho kom ruaj khov yuav ua rau koj lub twj tso kua mis nce thiab khiav thiab txo qis qis qis kom koj lub twj tso kua mis ib txwm ua haujlwm zoo.
