Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm ntawm kauv duct cua txias hauv engineering

A. Cov ntsiab lus rau kev teeb tsa thiab kev ua haujlwm ntawm cov kav dej rau cov tub yees

1. Qhov kawg ntawm cov yeeb nkab ntawm qhov kev nyab xeeb valve yuav tsum yog Ω-puab lossis T-puab, thiab qhov chaw nres nkoj tawm yuav tsum fim thaj chaw nyab xeeb. Lub kaw-off valve yuav raug teeb tsa ntawm qhov kev nyab xeeb valve thiab cov khoom siv. Thaum lub sijhawm ua haujlwm, nws yuav tsum nyob rau hauv txoj haujlwm qhib tag nrho thiab kaw nrog txhuas.

2. Cov kav hlau kav los ntawm phab ntsa lossis hauv pem teb yuav tsum muab cov hlau casing, thiab cov vuam yuav tsum tsis txhob muab tso rau hauv lub casing. Cov hlau casing yuav tsum tau yaug nrog phab ntsa lossis hauv pem teb, lossis hauv qab hauv pem teb, tab sis yuav tsum yog 20 hli siab tshaj hauv av. Qhov chaw nruab nrab ntawm cov kav dej thiab cov kav dej yuav tsum tau ntim nrog cov rwb thaiv tsev kub lossis lwm yam khoom tsis-combustible, thiab yuav tsum tsis txhob siv los ua kev txhawb nqa ntawm cov kav dej.

B. Cov ntsiab lus tseem ceeb rau kev tsim khoom thiab kev teeb tsa ntawm cov kav dej thiab cov khoom siv plua plav

1. Kev teeb tsa thiab tshem tawm cov plua plav yuav tsum nyob rau hauv txoj haujlwm raug, ruaj khov thiab ruaj khov, kev coj mus muag thiab xa tawm yuav tsum ua kom tau raws li cov qauv tsim, qhov tso cai sib txawv ntawm qhov ntsug yuav tsum tsis txhob siab tshaj 2 hli ib meter, thiab tag nrho qhov sib txawv yuav tsum. tsis ntau tshaj 10mm.

2. Lub qhov hluav taws xob thiab qhov hluav taws xob ntawm cov kav dej thiab cov khoom siv plua plav yuav tsum ncaj, cov yeeb nkab tawm ntawm lub tog raj kheej thiab lub khob hliav qab yuav tsum yog coaxial, thiab qhov eccentricity yuav tsum tsis txhob ntau tshaj 2 hli.

3. Qhov tso cai sib txawv ntawm qhov sib txawv ntawm cov kav dej thiab sab nraud ntawm cov plua plav collector lub tog raj kheej lossis cov duab plaub sab nraud yuav tsum tsis txhob siab tshaj 5%, thiab cov npoo sab hauv thiab sab nrauv yuav tsum du thiab sib xws hauv curvature.

C. Cov ntsiab lus tseem ceeb ntawm kev teeb tsa thiab kev ua haujlwm ntawm cov kav dej ntawm lub tshuab ua pa

1. Qhov nthuav tawm ntawm cov khoom siv kis tau tus mob ntawm cov kav dej ntawm lub tshuab ua pa yuav tsum tau nruab nrog lub hau tiv thaiv. Thaum cov cua nkag los yog cov yeeb nkab cua nkag ntawm lub tshuab ua pa ncaj qha mus rau qhov chaw, yuav tsum tau nruab ib lub vas tiv thaiv lossis lwm yam kev ntsuas.

2. Yog hais tias lub hauv paus ntawm lub kauv duct ntawm lub tshuab ua pa ncaj qha mus rau hauv lub hauv paus yam tsis tau siv lub shock-absorbing ntaus ntawv, yuav tsum tau siv ib khub ntawm inclined horns rau leveling.

3. Cov cua nkag thiab qhov hluav taws xob cov kav dej ntawm cov kav dej ntawm lub tshuab ua pa yuav tsum muaj cov kev txhawb nqa sib cais thiab yuav tsum ruaj khov rau hauv lub hauv paus lossis lwm lub tsev. Thaum cov kav dej txuas nrog rau lub kiv cua, lub flange nto yuav tsum tsis txhob rub los yog tsis muaj kev ntxhov siab. , rooj plaub yuav tsum tsis txhob dais qhov hnyav ntawm lwm qhov chaw kom tsis txhob deformation.
