Termoshayby rau kho polycarbonate. Yuav ua li cas ntxiv dag zog? Lus Qhia

Kev siv ntau ntawm polycarbonate nyob rau ntau qhov chaw muaj peev xwm ua tau vim yog cov yam ntxwv tshwj xeeb thiab zoo nkauj cov ntaub ntawv ntawm cov khoom siv no. Thaum txhim kho cov khoom ntawm polycarbonate, nws yog ib qhov tsim nyog yuav tsum tau coj mus rau hauv tus account qee yam ntawm cov khoom siv no. Yuav kom tswj tau qhov kev ua tau zoo ntawm cov vaj huam sib luag, nws yog qhov tsim nyog los xaiv cov fasteners kom raug. Yuav ua li cas xaiv cov thermocouples rau kho polycarbonate, thiab kuj yuav ua li cas nqa tawm lub installation, qhov no tsab xov xwm yuav qhia.

Cov khoom thiab cov khoom zoo txawv ntawm cov tshuaj polymer

1. Cov khoom muaj zog thiab yuav tsum tau ua cov cuab yeej zoo tshaj plaws.
2. Thermowashers rau kho ntawm polycarbonate yuav tsum resistant rau corrosion.
3. Thaum ua hauj lwm nrog yas, nws yog ib qhov tsim nyog yuav tsum tau mus rau hauv tus account nws high coefficient ntawm thermal expansion. Hard fixation yuav ua tau rau ib lub Frost nyob rau hauv lub rupture ntawm lub hniav, thiab nyob rau hauv lub tshav kub, o.
4. Lub ntsiab lus ceev nrooj yuav tsum tsis txhob thuam cov qauv ntawm tus qauv.

Fasteners

Cov kev xaiv noj thaum nruab ib lub qauv ntawm polycarbonate yog kev siv cov thermowells, uas yuav pab daws tau cov haujlwm hauv qab no:

• Muaj kev ruaj ntseg thiab txhim khu kev lag luam ntawm lub vas sab mus rau qhov kev txhawb nqa;
• Sealing ntawm qhov drilled nyob rau hauv polycarbonate rau lub installation ntawm washers, uas tiv thaiv hmoov av, kua thiab txias los ntawm nkag mus rau hauv cov qauv;
• Polycarbonate thiab cov khoom siv los ntawm cov thermowells raug, nthuav dav thiab daim ntawv cog lus tib lub sijhawm;
• Xim assortment ua rau nws tau xaiv cov fasteners hauv cov xim ntawm tus tsim nws tus kheej.

Cov thermowells siv los kho kho polycarbonate yog dab tsi?

Cov khoom siv rau kev tsim yog:

• Stainless hlau (kev pab cuam lub neej yog unlimited);
• Polypropylene (kev pab lub neej - 3-4 xyoos);
• Polycarbonate (yuav ua haujlwm txog 20 xyoo).

Termoshayba rau kev tuav pov hwm polycarbonate los ntawm cov hlau tsis muaj stainless yog siv rau kev tuav qhov loj thiab qhov chaw muaj zog cua ntawm cov txheej txheem hlau. Lub caij fastening tau muaj qhov zoo ib yam uas muaj kev nyuab siab me me hauv nruab nrab thiab ib lub qhov nyob hauv qhov chaw. Lub foob yog tsim los ntawm polyurethane rau hauv qhov chaw so. Rau kev ruaj ntseg ruaj ntseg, qhov kev ncua deb ntawm cov ntxhuav yog 25-30 cm.

Hnub no, cov fasteners uas cov yas lub tshuab ntxhua khaub ncaws hnyav heev. Txawm hais tias polypropylene fasteners yog raug ultraviolet tawg, uas txav cov khoom rau ntau xyoo. Vim li ntawd, lub canvas pib mus rau kev vam meej thiab tuaj yeem cev qhuav dej. Qhov zoo yog cov nqi qis, kev ua kom zoo nkauj thiab ntau hom xim. Cov khoom tsim thiab cov khoom muag.

Qhov nrov tshaj plaws yog cov thermocouples universal ntawm polycarbonate, tshwj xeeb tshaj yog thaum txhim kho cov nplooj ntawv pob tshab. Xws cov ntsiab lus tseem ceeb:

• Siv tsis tau vim kev kho tshwj xeeb los ntawm ultraviolet radiation;
• Harmoniously tag nrho nrog cov khoom tseem ceeb thiab yuav luag pom;
• Tsis txhob degrade thiab tsis hloov lawv cov khoom hauv lub cev thaum kub hloov;
• Vim lub fact tias lub tshuab ntxhua khaub ncaws yog tiaj tus, nws yog khi rau daim ntawv, tsis muaj kev puas tsuaj.

Cov neeg tsim khoom tsim cov thermowells nrog ib ceg (xaiv rau ib qho tuab ntawm daim ntawv) thiab tsis muaj ceg (yog universal).

Lub thermostow muaj xws li:

• Tus puck nws tus kheej nrog lossis tsis muaj ko taw;
• Sealant (polymer nplhaib);
• Npog (npog tshuab tooj liab lossis yas);
• (Feem ntau yog muag nyias).

Polycarbonate fastening cov cai

1. Thaum drilling qhov rau thermowells nyob rau hauv yas thiab cov qauv txhawb nqa, lub cuab tam yog ntsia ncaj qha perpendicular. Drilled txawm nyob rau ntawm lub qhov me me lub qhov yuav ua rau ua txhaum cai ntawm kev ceev nruj thiab dej ntawm lub vaj huam sib luag.
2. Siv tsuas ntse xyaum me ntsis zoo dua nrog central fixation (haum xyaum rau ib tsob ntoo), uas tsis plam thiab yuav tsis puas cov ntaub.
3. Lub qhov rau lub thermowell ua ob peb millimetres ntau tshaj qhov tuab ntawm txoj hlua khau ntawm nws tus kheej, kev xav txog cov lus pov thawj ntawm cov yas hauv qab ntawm tshav kub.
4. Siv cov pas hlau tsis muaj steel hlau nrog lub hau xwb.
5. Thaum lub sij hawm kev teeb tsa, qhov kev foob yuav tsum tau muab khov kho tawm tsam lub pob zeb polycarbonate, tab sis tsis yog nias.
6. Qhov kev ncua deb ntawm lub thermowells yog los ntawm 25 mus rau 70 cm, nyob ntawm seb qhov loj ntawm lub qauv thiab kev khiav hauj lwm rau cov neeg mob.

Lub qhov cub kub yog qhov zoo dua: nrog rau ko taw lossis dav hlau?

Ntau tus ntseeg hais tias vim yog lub hauv paus xws li lub qia ntawm lub thermowell, kev txhim kho ntau txhim khu tiav, lub sij hawm "nyem" daim ntawv los ntawm lub qhov muag ntsia hlau (thaiv cov ceg so) thiab txo qis "leaks" txo. Nws yuav tsum nco ntsoov tias polycarbonate thiab thermowells feem ntau muaj nyob rau hauv ntau qhov chaw, yog li ntawd tolerances rau cov ntawv tuab thiab yas yuav txawv ntawm li ntawm 1 hli. Vim qhov no, tej zaum yuav muaj kev nyab xeeb rau hauv tag nrho cov ntsiab lus txuas.

Kws txawj qhia thaum siv cov thermowells thoob cov "clamp" fasteners. Nyob rau hauv lub txias, "clamping" yog compensated rau los ntawm kev txo lub thickness ntawm daim ntawv polycarbonate.
