Wopanga ndi Wogulitsa Wabwino Kwambiri Wowonjezera (Wopereka Mphira)

Malo Olumikizirana

Cholumikizira cha Expansion chimagwiritsidwa ntchito makamaka pa zolumikizira zolumikizira pampu ya dredge ndi payipi, komanso kulumikiza mapaipi omwe ali padenga. Chifukwa cha kusinthasintha kwa thupi la payipi, chimapereka kuchuluka kwa kukulitsa ndi kufupika kuti chibwezeretse mpata pakati pa mapaipi ndikuthandizira kukhazikitsa ndi kusamalira zida. Cholumikizira cha Expansion chili ndi mphamvu yabwino yoyamwa kugunda kwamphamvu panthawi yogwira ntchito ndipo chimagwira ntchito yoteteza zida.

Expansion Joint ndi mtundu wa payipi ya rabara yokhala ndi kutalika kochepa komanso nthawi zambiri yochepera 1m kutalika. Ikhoza kupangidwa kuti ipirire mitundu yosiyanasiyana ya kupanikizika. Expansion Joints ikhoza kupangidwa ndikumangidwa kuti ipirire kupsinjika koyipa, monga "-0.1 MPa", komanso kupirira kupsinjika kwabwino, monga "1.0 MPa", "2.5 MPa", komanso ngakhale kupirira kupsinjika koyipa komanso kwabwino, monga "-0.1 MPa ~ 1.5 MPa", motero Expansion Joint imagwiritsidwa ntchito pamikhalidwe yosiyanasiyana ya kupsinjika.

Cholumikizira Chokulitsa chili ndi mitundu iyi: Cholumikizira Chokulitsa ndi Nipple Yachitsulo, Cholumikizira Chokulitsa ndi Sandwich Flange ndi Cholumikizira Chokulitsa ndi bore yochepetsera.

Mawonekedwe

(1) Ndi mitundu yosiyanasiyana ya kupanikizika, yoyenera kupsinjika koipa komanso kwabwino.
(2) Kukana bwino kwambiri kukanda
(3) Kutanuka kwabwino
(4) Kumwa bwino kwa shock

Magawo aukadaulo

(1) Kukula kwa Bore Yodziwika: 100 mm ~ 1300 mm
(2) Utali wa payipi: 0.2 m ~ 1 m (kulekerera: ± 1%)
(3) Kupanikizika kwa Ntchito: -0.1 MPa mpaka 3.0 MPa

Kugwiritsa ntchito

Cholumikizira Chowonjezera ndi gawo lofunikira pamakina ofunikira a Cutter Suction Dredger (CSD) ndi Trailing Suction Hopper Dredger (TSHD), chimagwiritsidwa ntchito mu makina a payipi yamadzi a jet, makina opopera mafuta mu thanki, chitoliro chakutsogolo ndi chakumbuyo cha pampu, ndi makina opopera mapaipi a deck. Ma Expansion Joints opangidwa ndi CDSR akhala akudaliridwa kwambiri ndi ogwiritsa ntchito akunyumba ndi akunja.

Ndikofunikira kusamala za ubale womwe ulipo pakati pa kutalika kwa Expansion Joint ndi malo oti muyikepo, chifukwa umagwirizana ndi moyo wa ntchito ya chinthucho. Nthawi zambiri kutalika kwa Expansion Joint kumakhala kochepa ndi 0 ~ 5mm kuposa malo omwe adayikidwira, ndipo malo okwanira oyikapo sayenera kupitirira 10mm pa Expansion Joint yayitali (pafupifupi 1m kutalika). Ngati malo oyikapo ndi akulu kwambiri, Expansion Joint nthawi zonse imatambasulidwa ndipo izi zitha kuwononga kapangidwe kake.

Mapayipi Odulira a CDSR amatsatira mokwanira zofunikira za ISO 28017-2018 "Mapayipi a rabara ndi mapayipi olumikizidwa, waya kapena nsalu yolimbikitsidwa, yogwiritsira ntchito kudulira - Kufotokozera" komanso HG/T2490-2011
