Hom ntawm boiler raj

Hluav Taws Kub Boiler

Hluav taws kub-tube boiler yog ib hom boiler uas cov roj kub kis tau los ntawm qhov hluav taws kub los ntawm ib los yog ntau tshaj cov kav dej uas dhau los ntawm lub thawv ntim dej. Lub tshav kub ntawm cov roj yog kis los ntawm cov phab ntsa ntawm lub raj los ntawm cov cua kub conduction, cua sov cov dej thiab nws thiaj li tsim cov chav. Hluav taws kub boilers yog thib peb ntawm plaub keeb kwm hom boilers: low-pressure tank los yog "haystack" boilers, flue boilers nrog ib los yog ob tug loj flues, hluav taws kub boilers thiab high-pressure boilers nrog ntau me me hlab.

Dej Tube Boiler

Dej raj boiler yog ib hom boiler nyob rau hauv uas dej circulates nyob rau hauv cov hlab rhuab externally los ntawm hluav taws. Cov roj yog hlawv nyob rau hauv lub cub tawg los tsim cov roj kub, uas ua rau cov dej sov hauv lub tshuab hluav taws xob. Hauv cov boilers me me, cov kav dej tsim hluav taws xob ntxiv tau muab cais rau hauv lub qhov cub, thaum cov khoom siv hluav taws xob loj dua tso siab rau cov raj dej uas ua rau cov phab ntsa ntawm lub cub tawg los tsim cov pa. High-pressure water tube boiler: Cov dej kub ces nce mus rau hauv chav nruas. Ntawm no, saturated chav yog rub tawm ntawm sab saum toj ntawm lub nruas.

Boiler Pipe Manufacturing txoj kev

Txoj kev tsim khoom ntawm nruab nrab thiab siab siab boiler steel yeeb nkab yog tib yam nrog seamless steel yeeb nkab, tab sis muaj qee qhov kev tsim khoom tseem ceeb yuav tsum raug sau tseg:

Kev kos duab zoo, ci ntsa iab, kub dov, txias kos, kub nthuav dav

Txoj kev kho cua sov siv hauv cov kav dej boiler

Kev kho cua sov yog ib txoj hauv kev hloov lub cev lub zog ntawm lub siab kub boiler yeeb nkab los ntawm cua sov thiab cua txias. Kev kho cua sov tuaj yeem txhim kho qhov microstructure ntawm kev kub siab boiler yeeb nkab, thiaj li ua tau raws li qhov xav tau ntawm lub cev. Toughness, hardness thiab hnav tsis kam yog tau los ntawm kev kho cua sov. Yuav kom tau txais cov yam ntxwv no, nws yog ib qho tsim nyog yuav tau txais quenching, annealing, tempering thiab deg hardening.

1. Quenching

Hardening, tseem hu ua quenching, yog qhov kub siab boiler yeeb nkab yog rhuab sib npaug mus rau qhov tsim nyog kub, ces sai sai rau hauv dej los yog roj kom txias sai, thiab txias nyob rau hauv huab cua los yog nyob rau hauv lub freezing cheeb tsam. Yog li ntawd lub siab kub boiler yeeb nkab yuav tau txais qhov yuav tsum tau hardness.

2. Tempering

Kev kub siab boiler yeeb nkab yuav nkig tom qab hardening. Thiab kev ntxhov siab los ntawm quenching tuaj yeem ua rau lub siab kub boiler yeeb nkab tapping thiab tawg. Txoj kev tempering yuav siv tau los tshem tawm brittleness. Txawm hais tias lub hardness ntawm high pressure boiler yeeb nkab yog sib dua, nws lub toughness yuav tsum tau nce los txo lub brittleness.

3. Kev sib tw

Annealing yog txoj hauv kev los tshem tawm cov kev ntxhov siab sab hauv ntawm kev kub siab boiler yeeb nkab. Txoj kev annealing yog tias cov hlau yuav tsum tau muab rhaub rau qhov kub thiab txias, tom qab ntawd muab cov hmoov tshauv qhuav, txiv qaub, asbestos los yog kaw rau hauv qhov cub, ces cia nws txias maj mam.

Peb tuaj yeem tsim txhua qhov ntau thiab tsawg ntawm boilers raj, raws li European, Suav, Asmeskas, Nyiv tus qauv.Nrog lub sijhawm xa khoom sai, lub sijhawm them nyiaj txhawb nqa.Txhua cov txheej txheem ntau lawm yog tswj nruj me ntsis. nrog rau qib siab ntawm qhov yuav tsum tau ua, tag nrho cov raj raug tshuaj xyuas ua ntej xa khoom. , thiab tseem lees txais kev tshuaj xyuas thib peb ua ntej xa khoom.

Kuaj

Cov yeeb nkab steel yuav tsum tau kuaj Hydraulic ib leeg. Qhov ntsuas siab tshaj plaws yog 20 MPa. Nyob rau hauv qhov kev sim siab, lub sij hawm ruaj khov yuav tsum tsis pub tsawg tshaj 10 S, thiab cov yeeb nkab hlau yuav tsum tsis txhob tso.

Tom qab tus neeg siv pom zoo, Qhov Kev Ntsuas Hydraulic tuaj yeem hloov tau los ntawm Eddy Tam sim no Kev Ntsuas lossis Kev Ntsuas Ntsuas Flux Leakage.

Nondestructive Test:

Cov kav dej uas xav tau kev tshuaj xyuas ntau dua yuav tsum tau kuaj xyuas ib qho los ntawm ib qho. Tom qab Kev Sib Tham Yuav Tsum Tau Txais Kev Pom Zoo los ntawm Pawg Neeg Saib Xyuas thiab tau teev tseg hauv daim ntawv cog lus, lwm yam kev sim uas tsis muaj kev puas tsuaj tuaj yeem raug ntxiv.

Flattening Test:

Tubes nrog ib txoj kab uas hla sab nraud loj dua 22 mm yuav tsum raug rau qhov kev ntsuam xyuas flattening. Tsis pom kev delamination, pob dawb, lossis impurities yuav tsum tshwm sim thaum tag nrho kev sim.

Hardness Test:

Rau Cov Yeeb Nkab Qib P91, P92, P122, Thiab P911, Brinell, Vickers, lossis Rockwell Hardness Tests yuav tsum tau ua los ntawm ib qho qauv ntawm txhua qhov ntau.

Khoov Test:

Rau cov yeeb nkab uas muaj qhov ntev tshaj NPS 25 thiab qhov ntev ntawm phab ntsa Thickness ratio yog 7. Lwm cov yeeb nkab uas muaj qhov sib npaug lossis tshaj NPS 10 Tej zaum yuav raug muab Kev Ntsuas Khoov rau hauv qhov chaw ntawm Kev Ntsuas Flattening Raws li kev pom zoo ntawm tus neeg yuav khoom

 

Ntim

Tej zaum muaj ntau pua txoj kev sib txawv rau kev ntim cov yeeb nkab, thiab feem ntau ntawm lawv muaj txiaj ntsig, tab sis muaj ob lub hauv paus ntsiab lus tseem ceeb rau txhua txoj hauv kev ua haujlwm tiv thaiv xeb thiab kev nyab xeeb ntawm hiav txwv.Our packing tuaj yeem ua tau raws li cov neeg siv khoom xav tau.

Cov kaus mom yas ntsaws ntawm ob sab ntawm cov yeeb nkab kawg

Yuav tsum zam los ntawm cov hlau strapping thiab thauj puas

Cov paib pob khoom yuav tsum sib xws thiab sib xws

Tib pob (batch) ntawm cov yeeb nkab steel yuav tsum tau los ntawm tib lub cub tawg.

Cov yeeb nkab steel muaj tib lub cub tawg, tib qib steel, tib yam specifications.
