China thermal insulation simbi pombi fekitari
Thermal insulation pombi inoshandiswa zvakanyanya mumvura uye gasi kutapurirana pombi network, kemikari pombi yekupisa kupisa engineering, peturu, indasitiri yemakemikari, yepakati yekudziya network, yepakati mhepo yekufefetera pombi, mainjiniya emagetsi, etc. Simbi yakavharwa simbi inosanganiswa nesimbi pombi.
Iyo yekupisa yekumisa chimiro chesimbi yakashongedzwa simbi inosanganisirwa yekupisa yekupisa simbi pombi inogona kupatsanurwa mumapoka maviri zvichienderana neakasiyana ekutsvedza modhi:
1.Yemukati inotsvedza mhando: iyo yekupisa yekumisikidza chimiro inoumbwa nekushanda simbi pombi, aluminium silicate, dhiza yekudzikisa layer, microporous calcium silicate, thermal insulation layer, simbi isina tsvina yekuisa simbi tambo, aluminium foil reflection layer, polyurethane thermal insulation layer, yekunze simbi pombi uye kunze anti-corrosion layer. Iyo yemukati inotsvedza mhando yekupisa inochengetedza simbi pombi inoumbwa nepombi inotakura svikiro, inoumbwa silicate kana microporous calcium silicate, yakasimba polyurethane furo plastiki, yekunze simbi pombi uye FRP goko anticorrosive inodzivirira layer. Iyo tekinoroji yekupisa yekurapa tekinoroji yemhando dzakasiyana dzepombi fittings yakakura uye mhando yakavimbika.
2. Ekunze inotsvedza mhando: iyo yekupisa yekuvharisa chimiro inoumbwa nekushanda simbi pombi, girazi shinda yekupisa yekupisa, aluminium foil reflection layer, simbi isina tsvina inosungirira bhandi resimbi, inotsvedza girodhi rutsigiro, mhepo insulation layer, yekunze inodzivirira simbi pombi uye yekunze anti-corrosion layer. .
1. Inner simbi pombi
2. Zinc yakapfuma primer
3. Sliding guide bracket
4. High tembiricha resistant glass wool
5. Aluminium foil reflector
6. Air insulation layer
7. Jacket simbi pombi
8. Outer simbi pombi anti-corrosion coating
Simbi yakavharwa simbi inoumbwa nesimbi inosanganisirwa pombi imwe yepasi pevhu yakananga yakavigwa mapaipi. Inogona zvakare kuvigwa pasi pevhu pasina kongiri chimiro, ndiko kuti, kuwedzera kwekupisa kwepombi yesimbi inoshanda kunoitwa mupombi yekunze, iyo inoderedza mutengo wezvinhu, inopfupisa zuva rekuvaka, inovimbisa kuchengetedzwa kwepombi yekudziya, uye inogona. kuve zvakachengeteka uye zvakanyanya kushandiswa munzvimbo dzakasiyana dzetembiricha, Inonyanya kukodzera kune yakanyanya tembiricha yekupisa pombi mapurojekiti. Tembiricha yebasa inogona kusvika 150 ℃ - 450 ℃. Iyo pombi inopera inowanzovharwa nepolyethylene firimu kana matatu-layer PE inotonhora inotenderedza tepi kudzivirira hunyoro kana mvura kupinda isati yaiswa kana panguva yekuvaka. Iyo yakawanda-layer yakasimudzwa inosunga yemafuta ekudzivirira zvinhu zvinogoneka kuderedza kurasikirwa kwekupisa. Panguva imwecheteyo, matanho ekudzora anotorwa pane yekunze sleeve pamusoro kudzivirira chizvarwa chebhiriji inotonhora, kuitira kuti ive nechokwadi chekudzora tembiricha yekunze sleeve anti-corrosion coating. Iyo multilayer aluminium foil reflective layer yakaputirwa ne thermal insulation material, iyo inonyatso dzikisa kurasikirwa kwekupisa uye inoita kuti pombi yehutsi iwedzere hupfumi uye inonzwisisika. Iyo drainage system yakavharwa zvizere, ine inochinjika marongerwo, inonzwisisika chimiro, chengetedzo uye kuvimbika. Iyo pombi yekuburitsa hunyoro pane simbi casing haingogone kuburitsa gasi rakanyorova munguva, asiwo inoshanda searamu chiratidzo chepombi yekushanda kwezuva nezuva. Muripo wekupisa wepombi unotora yepamusoro-mhando mabhero compensator, iyo inoiswa mune casing uye inoitwa yakananga yakavigwa fomu. Hapana chikonzero chekuisa chekutarisa zvakanaka. Basa rekuvaka riri nyore uye nguva yekuvaka ipfupi. Yakakodzera kufambisa chiutsi kana imwe midhiya iri pasi pe2.5MPa uye 350 ℃. Chigadzirwa chacho chinoshandisa pombi yesimbi seyekunze yekudzivirira layer, iyo ine zvakanakira simba rakakwirira, kwete nyore kukuvadza, nyore kuvaka uye kugadzirisa uye hupenyu hurefu hwebasa.
Kuti uderedze kupisa kwekupisa kwepombi kuenda kuvhu, thermal insulation composite layer inowedzerwa kunze kwepombi pane yepakati uye diki-dhayamita kupisa kutapurirana kwemafuta asina kuchena kana pombi yekudziya. Iyo inowanzo shandiswa yekupisa yekuvharisa zvinhu ndeye rigid polyurethane foam, uye tembiricha iri pakati pe18 ne120 madhigirii. Nyaya iyi yakapfava mukugadzirwa. Kuti uvandudze simba rayo, chigadziko chepamusoro-density polyethylene layer inoshandiswa kunze kwekupisa kwekushisa kwekushisa kuumba chimiro chekugadzirisa zvinhu kudzivirira kuti mvura yepasi ipinde mukati mekupisa kwekushisa. Seti yakakwana ye-high-pressure polyurethane foaming midziyo inoshandiswa kupfura kuputika kubviswa kwengura pamusoro pekunze kwepombi yesimbi uye corona kurapwa mukati memukati wepombi yekudzivirira yekunze, kuitira kuvandudza kushanda kwekubatanidza kwepombi yekupisa yekupisa. Iyo insulating layer material is a rigid polyurethane foam ine density ye60kg/m3 kusvika 80kg/m3. Mukaha uripo pakati pepombi yesimbi nekasingi wakazadzwa zvakazara uye une humwe simba rekubatanidza, kuitira kuti chizere chakasimba chigone kuumbwa pakati pezvikamu zvitatu zvepombi yesimbi, pombi yekunze yesleeve uye yekudzivirira. Polyurethane foam ine yakanaka mechanical zvivakwa uye thermal insulation properties. Mumamiriro ezvinhu akajairika, inogona kumira tembiricha ye120 degrees Celsius. Inogona kumira tembiricha ye180 madhigirii nekugadzirisa kana kusanganisa nezvimwe zvinhu zvekudzivirira.
Prefabricated polyurethane insulated simbi pombi yakakamurwa kuita matatu akaturikidzana kubva mukati kuenda kunze:
First floor: kushanda simbi pombi pasi
Zvinoenderana nedhizaini uye zvinodiwa nevatengi, pombi yesimbi isina musono, spiral simbi pombi uye yakatwasuka seam simbi pombi inowanzosarudzwa. Mushure mekunge pombi yesimbi inobatwa nekuputika kwepfuti yepamusoro, giredhi yekubvisa ngura yepombi yesimbi inogona kusvika SA2 muGB / t8923-1988 chiyero, uye kushata kwepamusoro kunogona kusvika r = 12.5 microns mu gb6060.5-88 standard.
Second layer: polyurethane insulation layer
Iyo yakaoma polyurethane foam purasitiki inopinzwa mugomba rakaumbwa pakati pepombi yesimbi neyekunze sheath nemuchina wepamusoro-unopupuma furo, uyo unozivikanwa se "tube in tube foaming".
Yechitatu layer: high density polyethylene inodzivirira layer
Yakafanogadzirwa kuita nhema kana yero polyethylene epurasitiki pombi dzine humwe madziro ukobvu. Polyethylene haina hwema, haina chepfu uye inonzwa kunge wakisi. Iine yakanakisa yakaderera tembiricha kuramba. Iyo shoma sevhisi tembiricha inogona kusvika - 70 ~ - 100 ℃. Iine kugadzikana kwakanaka kwemakemikari, inogona kudzivisa kukukurwa kweasidhi yakawanda uye mabhesi (isingamiri kune acids ine oxidizing properties), isinganyunguriki mune zvakawanda zvinonyungudutsa pakupisa kwekamuri, uye ine mvura yakaderera. Nekudaro, nekuti iri mutsara molecule, inogona kunyungudika zvishoma nezvishoma mune mamwe organic solvents pasina kuzvimba, Yakanakisa magetsi ekudzivirira. Basa rayo ndere kuchengetedza polyurethane insulation layer kubva kune michina yakaoma zvinhu, uye imwe yacho inopesana nekuora uye isina mvura. High density polyethylene polyurethane furo insulation simbi pombi inofanira kutevedzera SY / t114-2000 uye SY / t115-2001 zviyero.
