Txheej: fusion bonded epoxy txheej, min.thickness 300 microns

Pob: plywood rooj plaub, haum rau kev xa khoom los ntawm hiav txwv, huab cua, lossis tsheb ciav hlau, pallets rau ntau qhov ntau thiab tsawg.

Kev piav qhia ntau lawm:

1.End kev twb kev txuas: ob flanges

2.Qhov tag nrho ntev ntawm kev sib txuas tuaj yeem hloov kho, muaj qee qhov kev nthuav dav.Feem ntau, qhov tsim qhov siab tshaj plaws nthuav dav yog 50mm.

3.Lawv tuaj yeem hloov ob lub flanges ncaj yeeb nkab, thaum lub sij hawm kho, kho cov yeeb nkab uas puas lawm los yog txuas cov kav dej tshiab, thiab cov yam ntxwv kho tau ntev ua rau lawv yooj yim dua flange kav hauv daim ntawv thov kev tsim kho thiab kev teeb tsa.Lawv feem ntau txuas nrog nyob ib sab ntawm lub valve.

4.Lub bolts * txiv ntseej tuaj yeem siv ncaj qha rau kev txuas cov flange hauv cov kav dej.

5.Tam sim no, peb kuj tuaj yeem muab ib nrab ntawm bolts, uas yog, bolts nrog 50% bolt qhov.

Nws yog peb tus qauv tsim tshiab, uas txo qhov hnyav thiab tus nqi, muaj kev sib tw ntau dua.

Lub luag haujlwm thiab lub hauv paus ntsiab lus:

Lub luag haujlwm ntawm cov cuab yeej telescopic yog txuas cov twj, li qub thiab cov kav dej, thiab them nyiaj rau lawv.

Cov yeeb nkab compensator tuaj yeem txuas ntxiv axially nyob rau hauv ib qho chaw, thiab tseem tuaj yeem kov yeej qhov kev sib txawv los ntawm cov yeeb nkab sib txawv ntawm ib lub kaum ntse ntse.

Nws pab txhawb kev txhim kho thiab tshem tawm cov li qub thiab cov kav dej.Nws tuaj yeem txuas ntxiv dawb ntawm cov yeeb nkab txuas ntxiv.Thaum nws tshaj nws qhov kev nthuav dav, nws yuav siv cov kev txwv kom muaj kev nyab xeeb ntawm cov yeeb nkab.

Cov cuab yeej telescopic muaj ntau txoj kev hloov pauv hloov thaum lub sijhawm ua haujlwm kav dej.Cov kav dej ua haujlwm vim yog thermal expansion thiab contraction, thiab cov khoom tawg thiab lub zog ntawm cov crust tsim cov txiaj ntsig tseem ceeb ntawm cov nyiaj them poob haujlwm.

Kev teeb tsa:

Dismantling Joint yog sib sau ua ke los ntawm ob lub flanged compositive fittings, ua ib qho kev txiav txim ntawm lub flanged spigot thiab flange adaptor.

Nws tsim los muab kev hloov kho longitudinal (txog 50mm) hauv flanged systems.Nws muab txoj hauv kev yooj yim rau kev teeb tsa thiab tshem tawm cov khoom flanged los ntawm kev kho qhov kev ncua deb ntawm ob flanged khoom thiab tig puag ncig.

Lub installation tseem yooj yim thiab tsuas yog siv lub torque ciaj ntswj kom nruj lub zog siab steel lossis stainless-steel txuas bolts.

Nws tuaj yeem disassembled sai sai thiab yooj yim heev rau kev kho thiab tu cov li qub, twj lossis ntsuas ntsuas.

Nws ua kom yooj yim lub sij hawm xav tau rau kev saib xyuas thiab kev hloov kho hauv cov kav dej yav tom ntej thiab txo qis sijhawm rau tag nrho cov kav dej.

Qhov zoo:

1, Nws tuaj yeem tiv thaiv qhov cuam tshuam ntawm kev co ntawm cov kav dej.Vim tias muaj qee qhov kev hloov pauv hauv cov khoom siv telescopic, nws tuaj yeem muaj kev tiv thaiv ntawm cov raj xa dej thaum vibration.

2, Nws yog qhov tsim nyog rau kev teeb tsa thiab hloov lub twj tso kua mis thiab li qub.Nws muaj lub sijhawm nruab nrab ntawm lub cev lub cev thiab cov khoom siv nthuav dav, uas tuaj yeem hloov kho tau yooj yim raws li qhov loj me hauv cov txheej txheem ntawm kev teeb tsa thiab kev saib xyuas.

3, Nws muaj qee yam tsis zoo rau ntawm axial, transverse thiab angular thermal deformation.

Nyob rau hauv tag nrho, qhov kev nthuav dav sib koom ua ke muab kev yooj yim zoo rau kev teeb tsa thiab hloov ntau yam khoom siv dej thiab cov kav dej, cov kav dej, cov twj, cov ntsuas dej thiab cov li qub.

Cov khoom lag luam muaj kev tswj hwm ntau ntawm kev nthuav dav thiab kev cog lus los ntawm qhov kub thiab txias sib txawv hauv cov kav dej ntev.
