Feem ntau hais tias cov kav dej galvanized, cov kav dej galvanized yog siv rau cov roj, thiab cov kav hlau uas siv rau cua sov kuj yog cov kav dej galvanized. Galvanized kav yog siv los ua cov kav dej. Tom qab ob peb xyoos ntawm kev siv, ntau cov xeb thiab cov av tau tsim nyob rau hauv cov kav dej, thiab cov dej daj uas ntws tawm tsis yog tsuas yog ua rau cov khoom tsis huv, thiab nws yog sib xyaw nrog cov kab mob uas yug ntawm cov phab ntsa sab hauv tsis sib xws, thiab cov xeb ua rau. cov ntsiab lus siab ntawm cov hlau hnyav hauv dej, uas ua rau mob hnyav rau tib neeg lub cev.
Galvanized steel yeeb nkab txuas txoj kev: threaded, welded.
Roll groove kev twb kev txuas
(1) Cracking ntawm yob zawj weld
1. Smooth lub puab phab ntsa vuam ribs ntawm lub siab zawj ib feem ntawm lub nozzle kom txo tau qhov tsis kam ntawm dov zawj.
2, Kho cov axis ntawm cov yeeb nkab steel thiab cov khoom siv dov grooving, thiab yuav tsum tau cov yeeb nkab steel thiab cov khoom siv dov grooving kom qib.
3. Kho qhov zawj nias ceev, thiab qhov zawj ua lub sij hawm tsis tuaj yeem tshaj qhov kev cai, siv zog sib npaug thiab maj mam.
(2) Roll zawj steel yeeb nkab puas
1. Smooth lub puab phab ntsa vuam ribs ntawm lub siab zawj ib feem ntawm cov yeeb nkab qhov ncauj kom txo tau qhov tsis kam ntawm qhov dov zawj.
2, Kho cov axis ntawm cov yeeb nkab steel thiab cov khoom siv dov grooving, xav tau cov yeeb nkab steel thiab cov khoom siv dov grooving kom qib.
3. Kho qhov nrawm nrawm, qhov nrawm nrawm tsis tuaj yeem dhau qhov kev cai, siv zog sib npaug thiab maj mam.
4. Txheeb xyuas qhov dav thiab qauv ntawm cov menyuam txhawb nqa thiab lub siab rau cov menyuam ntawm cov khoom siv dov groove, thiab xyuas seb puas muaj qhov sib txawv ntawm qhov loj ntawm ob lub rollers, uas yuav ua rau qaug dab peg.
5. Siv lub vernier caliper los xyuas seb qhov zawj ntawm cov yeeb nkab steel puas tau teev tseg.
(3) Lub zawj tsim los ntawm lub tshuab dov zawj yuav tsum ua raws li cov cai hauv qab no
1, Qhov saum npoo ntawm cov yeeb nkab kawg mus rau qhov zawj yuav tsum du thiab tsis muaj qhov tsis sib xws thiab yob cov cim.
2, Qhov nruab nrab ntawm qhov zawj yuav tsum yog concentric nrog cov yeeb nkab phab ntsa, qhov dav thiab qhov tob ntawm qhov zawj yuav tsum ua tau raws li qhov yuav tsum tau ua, thiab xyuas seb hom clamp hom puas yog.
3. Siv cov roj nplaum rau ntawm lub nplhaib roj hmab sealing thiab xyuas seb lub nplhaib roj hmab sealing puas puas lawm. Lub lubricant yuav tsum tsis yog roj lubricant.
Welded kev twb kev txuas
1. Lub qhov ncauj ntawm cov yeeb nkab steel galvanized tsis nyob rau hauv txoj kab ncaj nraim thiab muaj teeb meem nrog lub qhov ncauj oblique ntawm cov yeeb nkab steel tom qab butting. Nws raug nquahu kom txiav cov yeeb nkab taub hau rau lub sijhawm luv luv ua ntej ua haujlwm.
2, Tom qab cov galvanized steel yeeb nkab nozzles txuas nrog, ob lub nozzles tsis nruj nreem txuas, uas ua rau cov thickness tsis sib npaug ntawm cov welded; thiab cov yeeb nkab yog elliptical vim nws tus kheej vim li cas los yog kev thauj mus los pob. Nws raug nquahu kom txiav cov yeeb nkab taub hau rau lub sijhawm luv luv. Txheej txheem dua.
3. Tom qab lub nozzles ntawm galvanized steel kav yog butted, hlwv tshwm sim ntawm nozzles:
4. Vim yog vim li cas thaum vuam.
5. Muaj zinc nodules nyob rau hauv lub nozzle, uas yuav ua rau vuam nyuaj thiab hlwv. Yog tias cov zinc nodules loj dhau thiab ntau cov kav dej, cov zinc nodules yooj yim yuav tsum tau muab tshem tawm.
Hlau kev twb kev txuas
1, Threaded buckle: Cov yeeb nkab hoop thiab threaded buckle tsis tuaj yeem tiv tauj tag nrho, loosen, txiav tawm qhov buckle random, thiab rov nruab cov xov.
2. Cov yeeb nkab steel thiab cov yeeb nkab hoop xov tsis sib xws thiab tsis tuaj yeem txuas tau. Cov yeeb nkab hoop yuav tsum tau hloov los yog cov cuab yeej yuav tsum tau kho thiab rov xov.
3. Nthuav luam tawm tom qab cov yeeb nkab steel yog threaded: Ntsuas seb cov phab ntsa tuab ntawm cov yeeb nkab steel puas tuaj yeem ua tau raws li tus qauv tuab ntawm cov yeeb nkab threaded.
