Dab tsi yog cov yam ntxwv ntawm finned tube technology

Cov qauv duab kos duab ntawm kauv finned tube qhia cov yam ntxwv hauv qab no ntawm cov cua sov saum npoo nrog kauv finned raj raws li cov khoom sib pauv cua sov:

(1) Ua kom lub tshav kub hloov mus rau sab nraud ntawm lub raj, cov kauv finned raj nthuav dav qhov chaw hloov hluav taws xob sab nraum lub raj. Thaum qhov ntev ntawm sab nraud yog tib yam, nws qhov chaw hloov hluav taws xob yog ob peb zaug lossis txawm tias kaum ob ntawm lub sijhawm ntawm cov hlab ntsha liab qab, txhim kho lub peev xwm hloov hluav taws xob thiab kev hloov hluav taws xob ntawm sab nraud ntawm lub raj.

(2) Lub compact qauv ntawm cov cua sov saum npoo ntawm cov kauv finned tube nras tsub kom lub tshav kub hloov mus rau ib chav tsev ntim, uas yuav txo tau lub ntim ntawm cov cua sov nto nyob rau hauv tib lub tshav kub hloov chaw.

(3) Txo qhov hnav ntawm cov cua sov saum npoo vim qhov hloov pauv tau zoo dua ntawm cov cua sov saum npoo ntawm cov kauv finned raj tuaj yeem txo qhov nrawm ntawm cov kua dej tawm sab nraud, yog li txo qhov hnav ntawm cov cua sov saum npoo. Vim hais tias cov yam ntxwv hais saum toj no ntawm kauv finned tube bundles, cov khoom siv hluav taws xob sib pauv siv lawv li cov khoom siv hluav taws xob sib txuas muaj qhov zoo ntawm cov qauv compact, tsis tshua muaj hlau noj, thiab cov nqi khiav lag luam tsawg. Yog li ntawd, lawv tuaj yeem siv rau hauv kev lag luam, tubular cua preheaters, convective evaporation cua sov qhov chaw ntawm boilers, nrog rau cov khoom sib pauv cua sov hauv metallurgical thiab tshuaj tshuab.

Kauv finned raj tau siv rau boiler economizers nyob rau txawv teb chaws raws li thaum ntxov 1960s. Txhawm rau txo cov pa luam yeeb hauv cov hluav taws kub tshauv hluav taws kub boilers thiab ua tiav lub hom phiaj ntawm kev txo qhov hnav ntawm cov neeg lag luam, cov qub Soviet Union, raws li kev tshawb fawb, tau hloov pauv ntau lub boilers siv kauv finned raj economizers.

Dab tsi yog qhov feem ntau siv rau cov raj finned?

1. Ib lub raj steel aluminium composite finned tube, muaj cov fins thiab lub hauv paus raj, uas yog: lub hauv paus raj yog steel coated aluminium composite raj nrog ib tug ua tiav txhuas txheej rau sab nrauv, cov fins yog txhuas fins nrog ib tug mus txog-qhov. nyob rau hauv nruab nrab, sib sau dov npoo ntawm qhov los ntawm-qhov, thiab cov fins yog txawm peem rau nrog tsau nyob deb claws. Lub hauv paus raj thiab aluminium fins yog tsau ua ke los ntawm brazing.

2. Cov dej cua kub cua kub exchanger tsim los ntawm steel aluminium composite finned tubes, nrog rau finned tubes, tus cwj pwm nyob rau hauv hais tias cov finned hlab yog steel raj aluminium finned hlab.

3. Ib txoj hauv kev ua rau steel aluminium composite finned tubes, uas muaj cov txheej txheem hauv qab no:

(1) Kev npaj cov khoom siv raw: Cov yeeb nkab hauv paus yuav tsum tau ua los ntawm steel coated aluminium composite yeeb nkab nrog cov txheej txheem txhuas ua tiav rau sab nrauv, thiab aluminium fins yuav tsum tau ua los ntawm alloy aluminium phaj nrog cov txheej txheem ntawm cov khoom siv brazing;

(2) Punching los ntawm cov raj: Cov hlau txhuas phaj nrog cov txheej txheem sib xyaw ntawm cov khoom siv brazing yog xuas nrig ntaus rau hauv lub tshuab xuas nrig ntaus, thiab tom qab ntawd ntau cov fins tau txuas mus rau hauv lub hauv paus raj;

(3) Cleaning of finned tubes: Clean the threaded finned tubes with alkaline (pH>7) tshuaj ntxuav tu;

(4) Soaking hauv cov tshuaj flux: Cov finned tubes ntxuav tau raus hauv lub tank flux;

(5) Pem hauv ntej rauv fixture fixture: Cov hlab finned soaked nyob rau hauv brazing flux yog txaus siab thiab positioned siv rau pem hauv ntej furnace fixture fixture fixture;

(6) Rauv brazing: Tswj cua brazing yog siv los txuas ntxiv braze cov hlab finned.
