Txhua txhua xyoo, cov kav dej los ntawm cov ntaub ntawv Polymeries tshiab tshwm rau ntawm kev ua lag luam, thiab cov fittings ntawm cov qauv tshiab tshwm sim. Tag nrho cov ntawm lawv feem ntau yooj yim, ua haujlwm nrog lawv yog kev txaus siab, nrog qee "cam khwb cia" Cast-hlau "tsis sib piv! Tab sis yuav ua li cas cov ntaub ntawv tshiab thiab cov fittings coj nrog lub sijhawm?

Cov kav dej ua los ntawm cov ntaub ntawv polymeric thiab hlau-yas tsis ntshai, thiab muaj peev xwm mloog kaum xyoo nrog kev tuav kom zoo. Txawm li cas los xij, lawv muaj lawv cov kev qaug zog, thiab yog tias lawv tsis quav ntsej, nws yuav nyuaj rau qhov tshwm sim nrog cov raj xa dej.
Ua rau ntawm cov yeeb nkab tawg
Feem ntau ntawm cov uas raug yog ua thaum txhim kho. Cov feem ntau muaj xws li:
- Kev siv cov kav dej, fittings thiab cov cuab yeej sib dhos ntawm ntau cov chaw tsim khoom. Txawm hais tias kev ua raws tsis yog kev lav nyob hauv qhov no. Gost txwv Tsuas yog qhov siab tshaj plaws tso cai sib txawv ntawm txoj kab uas hla los ntawm cov kav dej ntawm cov phab ntsa loj tshaj plaws.
- Ib qho tsis sib xws ntawm cov yeeb nkab ua ntej kev sib txuas.
- Kev siv cov foob pob uas tsis haum thiab cov khoom sib xyaw ua ke uas muaj cov tshuaj phem rau cov kav dej thiab cov fittings.
- Cov pa phem ntawm cov chaw sib txuas ntawm fittings thiab kav dej.
- Kev teeb tsa tsis raug ntawm cov tebchaw thaum cov rings lossis xov cov khoom yoog tsis tau rub mus rau qhov txiav cov yeeb nkab, ntxiv rau thaum qhov kawg ntawm cov kav dej tsis tau.
- Qhov tsis sib xws xav tau rau lub zog thov rau hauv phau ntawv Mounting twj.
- Kev teeb tsa ntawm cov kav dej uas nyob ib sab los ua qhov sib txawv, nrog axis phim, ua rau khoov lossis torque, kis tau rau qhov haum.
Kev yuam kev tseem ceeb thaum txhim kho cov kav dej polymer - tsis ua raws nrog cov kev cai teeb tsa. Nco ntsoov ua kom cov kav dej kav thiab cov fittings tsis raug rau kev sib kis tau ntau dhau lawm. Yog tias muaj ib qho ntawm cov raj xa hluav taws tau muaj kev puas tsuaj me me, nws yog qhov zoo dua los hloov nws. Txawm hais tias cov yeeb nkab bay yog qhov dua yog yam tsis txiav ntim nrog rab riam. Txhawm rau zam kev puas tsuaj nyob rau hauv cov chaw ntawm cov zaj los ntawm kev teeb tsa tsev, nws yog ib qho tsim nyog los tso cov yeeb nkab hauv lub hyelze ntawm corrugations. Yog tias koj nruab cov kav dej thaum lub caij ntuj no, nco ntsoov tias qhov vuam vuam tsuas yog nyob ntawm ib qho kub ntxiv (tsawg kawg 5 ° C). Thiab tau kawg, tsis txhob hnov qab tias cov cuab yeej thiab cov kav dej yuav tsum yog huv.

Kev txhim kho ntawm cov kav dej polymer yuav tsum tau nqa nrog kev pab ntawm kev kho tshwj xeeb txhim kho, clamps thiab clips. Yees duab: Tioror
Thaum txhim kho polymer thiab hlau-yas cov kav yas, nws yog ib qho tseem ceeb kom tiv thaiv cov kav dej los ntawm kev puas tsuaj. Yees duab: Tioror
Cov kav dej yuav tsum tsis txhob khoov duav lossis tensile load; Tsis txhob txawv ntawm txoj hlab axis. Yees duab: Viega.
Tau pipes thiab thaum lub sijhawm ua haujlwm. Khov txias, raug rau ultraviolet, dhau ntawm qhov siab tshaj plaws pub nyiaj siab thaum lub sij hawm kev kuaj qib hydraulic - txhua qhov no tuaj yeem ua rau cov zis ntawm cov yeeb nkab tawm.
Yuav ua li cas tso cov kav dej
Ntawm no cov lus pom zoo yuav yog qhov yooj yim: cov tswv yim yuav tsum ua raws li cov cai rau kev tso cov kav dej ntawm ib hom lossis lwm yam thiab ua haujlwm zoo thaum ua haujlwm. Nws yog tsis yooj yim sua kom siv ntau zog quab yuam, thiab thaum ua haujlwm tsuas yog siv cov cuab yeej zoo. Qee hom fittings yuav tsum muaj cov cuab yeej tshwj xeeb uas tuaj yeem kim. Tab sis koj yuav tsum tsis txhob lees nws. Nyob rau hauv rooj plaub heev, lub cuab yeej tuaj yeem xauj tsev.
Ntawm cov kev ua yuam kev nquag tuaj yeem hu ua cov teeb tsa ntawm cov kav dej yam tsis tau noj rau hauv lawv cov coefficient ntawm linear nthuav. Hauv cov ntaub ntawv polymeric, nws yog qhov txaus txaus. Yog tias, piv txwv li, submarine los ntawm tus collector rau cov khoom siv cua sov nyob hauv ib txoj kab ncaj qha, thiab tom qab ntawd qhov ntev deformitate mus rau cov ntawm cov khoom siv cua sov. Koj tuaj yeem zam qhov no siv qee cov tswv yim yooj yim.
1. Muab cov khoom xa los ntawm cov dej khov rau cov khoom siv cua sov nrog lub thib 90 °, tawm cov phiaj xwm ncaj nyob rau hauv pem hauv ntej ntawm lub rade tsis ntau tshaj 1.5 m.
2. Kho cov ntawv txuas nrog ntawm.
3. Kho kom zoo rau qhov kawg ntawm kev sib txuas ntawm cov hlab nrog lub radiator.
Nrog rau ib qho qhib gasker ntawm polymer raj, kub tau muab suav thiab them nyiaj los ntawm kev siv G-thiab P-puab txhawb lossis siv cov raj hlau-polymer.
