Majoini ekuwedzera rabha eDN200 akaputirwa akagadzirwa uye agadzirira kutumirwa. Zvigadzirwa izvi zvinopihwa zvakanyanya kumapurojekiti einjiniya ekunze kwenyika anosanganisira kupa mvura & kuyerera kwemvura, indasitiri yemakemikari, mafekitori emagetsi, HVAC uye kurapwa kwemvura yegungwa. Huwandu huri kuramba huchiwedzera hwemakambani eEPC epasi rese nevatengi vemapaipi vanowanzo sarudza majoini ekuwedzera rabha akaputirwa, kunyanya nekuti ma connectors aya anochinjika anogadzirisa marwadzo asingaperi panguva yekushanda kwepaipi kwenguva refu.

Masisitimu emapaipi anotambura nekukanganiswa kwekushanduka kwekushisa, kudedera kwemuchina kubva mumidziyo inotenderera, kusarongeka kwekuisa uye kugadzikana kwenheyo. Zvikamu zvemapaipi esimbi akasimba zvinogona kukanganiswa nekupwanyika kweweld uye kubuda kweflange kana zvamanikidzwa kakawanda. Kudedera kunoramba kuripo kunokonzerwa nemapombi emvura nemablower kunotumira ruzha kuburikidza nemagadzirirwo emapaipi, zvichikonzera kukuvara kwemavharuvhu, zvishandiso nemidziyo mikuru mushure mekushanda kwenguva refu. Majoini ekuwedzera rabha ane flanged akagadzirwa zvakanyanya kuti akunde matambudziko ese aya.

Rudzi urwu rwerubha rine hunhu hwakakosha. Muviri werubha wakashongedzwa nejira rakasimbiswa rine machira akawanda uye elastomer inoshanda zvakanyanya, inoenderana necarbon steel floating flanges. Inotora kufamba kwakasiyana-siyana kusanganisira kuwedzera nekudzika kweaxial, lateral offset uye angular deflection. Nekuda kwechimiro chayo che elastic, rubha rinotambanudza rinonyatsobvisa kuzununguka kwemuchina, rinoderedza ruzha rwemapaipi uye rinodzivirira kutenderera kwe vibration kuburikidza ne network yese yepiping. Zvinhu zvakawanda zve elastomer zvakaita seEPDM, NBR uye natural rabber zvinogona kushandiswa pakuisa mvura yakachena, tsvina, weak acid & alkali liquid, mafuta nezvimwe zvinoshandiswa, zvichipa simba rakanaka rekudzivirira kukwegura uye kurwisa ngura.

Zvichienzaniswa nemajoini ekuwedzera esimbi, majoini ekuwedzera erabha ane flange anoiswa zviri nyore pasina maitiro akaomarara ekutanga kutambanudza, achishivirira kusarongeka kudiki panguva yekuunganidza panzvimbo. Anoramba achishanda zvakanaka pakusunga nekudzora ruzha zvakanyanya. Chimiro chakareruka chinoderedza mari yekufambisa uye chinoderedza zvakanyanya mari yekugadzirisa yenguva dzose kune vashandisi vekupedzisira. DN200 (8 inch) saizi yakajairika inoshandiswa zvakanyanya muzviteshi zvepombi hombe nepakati, mapaipi emvura anotenderera uye mapaipi ekugadzirisa. Saizi dzakagadzirwa kubva kuDN50 kusvika kuDN1200 dziripo, pamwe chete nemakirasi ekumanikidza ePN10 nePN16 kuti zvigutse zvinodiwa zvakasiyana zvepurojekiti.

Majoini edu ekuwedzera rabha anowanikwa zvakanyanya mumabasa emvura emaguta ekune dzimwe nyika, mumafekitori ekuchenesa mvura yakasviba, masisitimu emhepo inotonhodza yeHVAC, mapaipi ekufambisa petrochemical, mapaipi emugungwa uye macircuits ekutonhodza emagetsi. Kuisa majoini ekuwedzera rabha zvakanaka kunobvisa kushushikana kwekupisa uye kwemuchina mukati memapaipi, kunodzivirira mapombi nemavharuvhu, kunoderedza kukundikana kwekubuda kwemvura uye kuwedzera hupenyu hwebasa remapombi ese. Izvi zvinobatsira mapurojekiti ekune dzimwe nyika kuderedza mari yekushandisa kwenguva refu nekugadzirisa, zvichiita kuti joini yekuwedzera rabha ive chinhu chakakosha muinjiniya yemazuva ano yekufambisa mvura.
