Dab tsi yog hnav cov feem ntawm cov twj muaj ntau theem thiab yuav tshuaj xyuas thiab tswj lawv li cas?

Tso lus
Kev hnav cov multistage twj feem ntau suav nrog Shafts, ntaub ntsaws, ris tsho, txhua yam khoom hnav tsis tu ncua thiab hloov pauv yog tias tsim nyog. Kev tsis saib xyuas hauv kev ua haujlwm tej zaum yuav ua rau ua haujlwm tsis zoo.
1. Multistage twj tso kua mis impeller
Txheeb xyuas cov hnav thiab corrosion ntawm lub twj tso kua mis impeller thiab hloov nws nrog ib qho tshiab yog tias tsim nyog.
2. Hnav cov nplhaib thiab kev tshem tawm
Txiav txim siab txog qhov tseeb. Yog hais tias qhov kev txiav txim siab ntau tshaj plaws los yog tshaj tus nqi tso cai, cov nplhaib hnav ntawm ntu nruab nrab ntawm cov ntu thiab cuam tshuam nrog tus neeg ua haujlwm cuam tshuam. Cov kev tso cai tshem tawm nruab nrab ntawm cov impeller thiab cov nplhaib hnav tau qhia hauv qab rooj hauv qab no.
| Yam | DS40, DS50 | DS80 | DS100, DS150 | DS200 | phiaj qhia ntawv |
| Tsawg kawg nkaus kev tshem tawm (hli) (tshiab seem) |
0 .3 | 0 .35 | 0 . 4 | 0 . 45 | 1 |
| 0 .45 | 0 .5 | 0.55 | 0.6 | 2 | |
| {{0 {}}. 6 Qhov kawg nkaus (hli) (qub seem) |
0 .6 | 0.7 | 0.8 | 0.9 | 1 |
| 0.9 | 1.0 | 1.1 | 1.2 | 2 |
Qhov kev tshem tawm yog txoj kab uas hla
Performance index:
1: Qhia cov hlau lossis cov hlau muag muag
2: Qhia tias Stainless hlau
3. Tshuav
Nws raug nquahu tias lub twj tso kua mis impeller yuav dynamically sib npaug ntawm lub tshuab muaj zog sib npaug. Tus nqi tsis sib haum yuav tsum xa mus rau ISO1940, Q =<2.5. The rotor dynamic balancing should be carried out according to the contract.
4. Cov ntsiab lus ntawm ntau-theem kev nqus ncej
Txhawb nqa lub twj tso kua mis ncej rau ntawm cov chaw txhawb nqa (V-puab cov roj \/ cov menyuam) thiab kuaj qhov ntsuas (siab tshaj plaws tso cai radial runior {
| Ua haujlwm ceev | Tsawg dua los yog sib npaug rau 3000 rpm | >3000 rpm |
| Tshaj plaws tso cai radial runout | 0 . 025 | 0 . 02 |
Yog tias cov radial runout ntau dua li cov kev tso cai rollout tus nqi, tus ncej yuav ncaj ncaj nyob rau hauv lub caij txias lossis kub. Yog tias qhov ua haujlwm kub ntawm cov multistage twj tshaj 100 degree, tus ncej ntawm cov multistage twj tso kua mis tsis tso cai kom ncaj.
5. Stawb thawv
Txheeb xyuas qhov kev ua txhaum ntawm cov tes tsho. Yog hais tias txoj kab uas hla kev tsis pub dhau 1 hli nyob rau hauv tus ncej loj (tsis tsim nyog polished), yog tias tsim nyog polished), nws tuaj yeem rov qab ua nrog cov nplhaib ntim raws qhov loj me.
6. Cov kabmob
Ntxuav cov kabmob ntawm lub multistage twj tso kua mis nrog cov roj huv, thiab hloov nws nrog cov kabmob tshiab yog tias nws puas.
7. Nyuaj nruas nruas thiab cov khoom siv nruas
Tshawb xyuas qhov ntev me me ntawm qhov sib npaug Nrov Nrig Nrov Hla ntawm cov neeg multistage twj tso kua mis thiab lub cheeb ntawm txoj kev sib npaug ntawm lub tes tsho; Qhov kev tso cai tshaj plaws (hli) yog raws li hauv qab no:
| DS40, 0550 | DS80, DS100 | 05150 ,05200 | phiaj qhia ntawv |
| 0 . 3 | 0 . 4 | 0 . 6 | 1 |
| 0 . 4 | 0 . 5 | 0 . 7 | 2 |
Qhov sib txawv yog qhov sib txawv ntawm txoj kev sib txawv.
