Cov Khoom Ntawm Kev tawg-pov thawj Distribution Box

Feem ntau, cov khoom siv casing ntawmtawg-cov ntaub ntawv pov thawjyuav tsum muaj lub zog siab, tiv thaiv corrosion, cuam tshuam tsis kam, thiab tawg tau zoo - ua haujlwm pov thawj. Qhov kev xaiv ntawm cov khoom tawg -cov ntaub ntawv pov thawj feem ntau yog nyob ntawm lawv qhov chaw ua haujlwm. Cov ntaub ntawv muaj xws li hauv qab no

 

1. Cast Aluminium / Aluminium Alloy

Cov khoom siv ntau tshaj plaws rau kev tawg-cov ntaub ntawv pov thawj ntawm lub khw.

Qhov zoo: Lub teeb yuag, zoo thermal conductivity, yooj yim rau txheej txheem, thiab tus nqi nruab nrab.

Txheej txheem: High-kub tuag casting. Qhov saum npoo feem ntau yog kho nrog electrostatic txau los txhim kho corrosion kuj.

Ib puag ncig siv tau: Feem ntau cov nroj tsuag tshuaj, roj teb, drilling platforms, thiab lwm yam khoom siv hluav taws xob tawg.

Lus Cim: Txwv tsis pub corrosion; tsis haum rau siab ntsev tsuag los yog muaj zog acid / alkali ib puag ncig.

 

2. Cam khwb cia hlau

Kev tawg ib txwm muaj- cov ntaub ntawv pov thawj, hnyav heev.

Qhov zoo: muaj zog txhua yam muaj zog heev, cuam tshuam tsis kam, thiab muaj zog compressive zog.

Disadvantages: hnyav heev, tsis yooj yim rau installation thiab txij nkawm, thiab kuj tsis zoo corrosion kuj, nquag xeb.

Ib puag ncig tsim nyog: Underground thee mine gas ib puag ncig, hnyav kev cob qhia, thiab lwm qhov chaw uas muaj kev xav tau siab rau kev siv tshuab.

 

3. Stainless hlau
Feem ntau, 304 lossis 316L stainless hlau yog siv.

Qhov zoo: Muaj zog tiv thaiv corrosion, zoo nkauj zoo nkauj, xeb - pov thawj, thiab siab txhua yam muaj zog.

Qhov tsis zoo: tus nqi siab dua, kev ua haujlwm nyuaj dua (kev xav tau siab rau vuam thiab tawg- pov thawj kho qhov chaw).

Ib puag ncig tsim nyog: Offshore platforms, nkoj, khoom noj khoom haus thiab chaw ua haujlwm tshuaj, ib puag ncig uas muaj zog acid thiab alkali corrosion, thiab cov chaw uas yuav tsum tau ua kom huv.

 

4. Carbon hlau
Welded steel daim hlau, feem ntau yog siv nyob rau hauv thaum ntxov los yog tej yam hnyav kev siv.

Qhov zoo: Cov neeg kho tshuab siab heev, muaj zog load-cov kabmob muaj peev xwm, tus nqi qis.

Txheej txheem: Welded los ntawm siab - zoo carbon structural steel, ces sprayed tom qab xeb tiv thaiv kev kho mob.

Disadvantages: hnyav heev, tsis zoo corrosion kuj.

Ib puag ncig tsim nyog: Underground thee mines (tsis yog-stainless steel yuav tsum), cov nroj tsuag loj loj, cov khoom siv nrog kev co siab.

 

5. Engineering Plastics / iav Fiber Reinforced Unsaturated Polyester Resin
Feem ntau yog hais txog molding plastics lossis fiberglass.

Qhov zoo: Antistatic, tsis tshua muaj zog corrosion kuj, zoo rwb thaiv tsev, lub teeb yuag.

Disadvantages: Tsawg mechanical zog dua hlau, tsis zoo cua sov dissipation.

Ib puag ncig tsim nyog: Cov tshuaj lom neeg muaj zog heev, qhib sab nraum zoov- huab cua qhov chaw, cov ntawv thov xav tau kev ua haujlwm siab rwb thaiv tsev.

 

Tsis tas li ntawd, cov khoom siv hluav taws xob raug tawg hauv qhov tawg- cov thawv pov thawj feem ntau yog ua los ntawm 304 stainless hlau los tiv thaiv xeb. Hauv qee qhov kev tsim tshwj xeeb, txawm tias siab dua -qib alloy cov ntaub ntawv xws li npib tsib xee- cov alloys yog siv.
