Nyob rau hauv Jinbin Rhiav, muaj ntau yam kev cai tsim rojdamper li qubrau cov neeg siv khoom tau pib ntim khoom thiab npaj rau kev xa khoom. Qhov loj me txawv ntawm DN405/806/906, thiab nws yog ua los ntawm carbon hlau. Cov pa roj carbon steel cua damper, nrog rau nws cov yam ntxwv ntawm "siab ntev, muaj zog sealing thiab tus nqi qis", zoo kawg nkaus ua tau raws li cov kev ua haujlwm nyuaj thiab kev tswj hwm tus nqi ntawm cov mining thiab plua plav tshem tawm kev lag luam, thiab tau dhau los ua qhov kev xaiv tseem ceeb rau kev tswj cov kav dej hauv ob qhov xwm txheej no.

Los ntawm qhov kev xav ntawm kev ua haujlwm siab ntev, hauv cov mining thiab cov plua plav tshem tawm, cov cua li qub yuav tsum tau tiv taus qhov kev yaig mus ntev ntawm cov plua plav siab, cov khoom cuam tshuam thiab kev hloov pauv ntawm lub sijhawm. Carbon steel puag khoom nws tus kheej muaj siab rigidity thiab hardness. Tom qab quenching, sandblasting los yog txau cov coatings hnav-tiv taus (xws li epoxy resin, ceramic hais), nws hnav tsis kam tuaj yeem txhim kho ntxiv, tiv thaiv kev hnav ntawm cov khoom tawv tawv xws li ore plua plav thiab thee plua plav, thiab zam qhov kev sib khi tsis ua haujlwm los ntawm kev deformation ntawm lub phaj valve thiab lub rooj zaum valve vim kev yaig. Lub caij no, cov qauv carbon steel muaj lub zog siab thiab tuaj yeem tiv taus qhov hloov pauv ntawm ± 5kPa hauv cov pa cua. Nyob rau hauv cov xwm txheej xws li cov cua hauv av thiab cov plua plav tshem tawm hauv kev lag luam mining, cov pa tawm tsis zoo yuav ua rau lub cev tsis zoo ntawm lub cev, ua kom muaj kev ruaj ntseg mus ntev.

Nyob rau hauv cov nqe lus ntawm sealing kev ua tau zoo thiab compatibility, cov plua plav tshem tawm kev lag luam muaj nruj kev cai rau kev sealing kev ua tau zoo ntawm cov pa ducts. Cov pa roj carbon steel cua li qub, los ntawm cov txheej txheem sealing zoo thiab ua ke nrog cov roj hmab tiv taus lossis fluorine roj hmab sealing qhov chaw, tuaj yeem ua tiav sealing zoo thiab tsis txhob txo cov plua plav tshem tawm vim huab cua to. Ntxiv mus, cov pa roj carbon steel tuaj yeem tsim los ntawm kev vuam, ua kom yooj yim rau kev tsim cov pa loj loj (xws li 2m × 1.5m), uas yog tsim rau cov kev xav tau ntawm cov qhov cua loj thiab cov pa loj ntawm cov plua plav tshem tawm hauv kev lag luam mining. Nyob rau hauv sib piv, cov ntaub ntawv zoo li stainless hlau yog feem ntau welding deformation thaum lub sij hawm loj-scale ua thiab muaj nqi ntau dua.

Kev lag luam thiab kev ruaj ntseg yog qhov zoo tshaj plaws. Tus nqi ntawm cov khoom siv roj carbon steel tsuas yog ib feem peb ntawm 304 stainless hlau. Daim ntawv thov batch tuaj yeem txo qhov kev nqis peev thawj zaug hauv kev ua haujlwm mining thiab plua plav tshem tawm. Lub caij no, cov pa roj carbon steel damper valve muaj cov qauv yooj yim thiab muaj zog tivthaiv universality (xws li valve shafts thiab actuator interfaces). Nws yog qhov yooj yim los hloov qhov chaw thaum lub sijhawm tu tom qab tsis tas yuav muaj cov cuab yeej tshwj xeeb. Txawm hais tias muaj xeb me ntsis ntawm qhov chaw, nws tuaj yeem kho los ntawm sandblasting rau kev tshem tawm xeb thiab siv cov xim pleev xim. Kev ua haujlwm thiab kev saib xyuas tus nqi qis dua li ntawm cov khoom siv alloy flue gas dampers.

Jinbin Valve, 20-xyoo-laus valve cua damper valve chaw tsim khoom, tsim thiab tsim khoom raws li cov neeg siv khoom xav tau. Yog tias koj muaj lwm yam kev xav tau, thov hu rau peb hauv qab no thiab koj yuav tau txais lus teb tsis pub dhau 24 teev!
