Chii chinonzi expansion joint?
Joini yekuwedzera ipaipi inoshanda zvakanyanya ine hurefu hupfupi, kazhinji isingapfuure mita imwe. Inoshandiswa zvakanyanya nekuda kwekugona kwayo kutsungirira huwandu hwakawanda hwekumanikidzwa uye inogona kugadzirisa kumanikidzwa kusina kunaka, kumanikidzwa kwakanaka, uye mamiriro akaoma ekushanda. Semuenzaniso, mamwe majoini ekuwedzera anogona kutsungirira kumanikidzwa kusina kunaka kwe -0.1MPa, mamwe anogona kutsungirira kumanikidzwa kwakanaka kweanosvika 2.5MPa, uyevamweinogona kushanda zvakadzikama muhuwandu hwekumanikidzwa kubva -0.1 kusvika +1.5MPa. Kushanda uku kunochinjika kunoita kuti ive chinhu chakakosha chekiyisisitimu yemapaipi emuchina wekuchera mvura.
Chinangwa chikuru chekuwedzera kwejoini
Mumidziyo mikuru yekuchera (yakadai seCSD neTSHD),Majoini ekuwedzera eCDSRanonyanya kushandiswa muzvikamu zvakakosha zvinotevera:
- Kubatana kunochinjika pakati pepombi yematope nepaipi
- Kubatana pakati pemapaipi
- Muripo uye kubatanidzwa kwepombi dzedeki dzakatarwa
Nekuda kwekuchinjika kwepaipi, jira rekuwedzera rine kugona kwe telescopic, izvo zvinogona kutsiva musiyano uripo pakati pemapaipi, zvichiita kuti kuiswa nekugadziriswa kwemidziyo zvive nyore. Panguva imwe chete, inogona kuderedza kuzununguka panguva yekushanda, kuderedza kukuvara kwemidziyo kunokonzerwa nekuzununguka, uye kupa vimbiso yekuti sisitimu yese yemapaipi ichave yakavimbika.
Mhandoyejoini yekuwedzera yeCDSR
Chikamu chekuwedzera cheCDSR chiriinowanikwa nemhando yesimbi yeflange uye mhando yerabha yeflange, kusanganaingzvinodiwa zvakasiyana zvekugadzira mapaipi nenzvimbo dzekuisa.
Hunhu hwekushanda
1. Mhando dzakasiyana-siyana dzedzvinyiriro
Chikamu chekuwedzera cheCDSR chinoshanda zvakanaka mukutsungirira kumanikidzwa kwakaipa uye kwakanaka, chinogona kuenderana nemamiriro chaiwo ekushanda emazinga akasiyana ekumanikidzwa, uye chine mashandisirwo akasiyana-siyana.
2. Kudzivirira kupfeka kwakanaka
Zvinhu zvepaipi uye tekinoroji yakakosha zvinoita kuti pani yekutambanudza irambe yakasimba kana yakatarisana nematope netsvina, uye inogara kwenguva refu.
3. Kukwanisa kukura zvakanaka
Chigadzirwa ichi chine mwero wakati wekupfava uye kukura, izvo zvinogona kuderedza zvikanganiso zvekuisa uye kuwedzera kupisa uye kudzikira kwemapaipi, nokudaro zvichivandudza kugadzikana kwese kwehurongwa hwemapaipi.
4. Mhedzisiro yakakosha yekunyudzwa kweshock
Chimiro chepombi chinochinjika chinogona kuderedza kutapurirana kwekudengenyeka kwemidziyo, kuchengetedza pombi nenzvimbo dzepombi, uye kuderedza njodzi yekukundikana.
Magadzirirwo ehunyanzvi
Kudzvanywa kwemhando: -0.1MPa kusvika +3.0MPa
Kureba kwechubhu: 200mm kusvika 1000mm
Dhayamita yezita: 100mm kusvika 1300mm
Izvi zvehunyanzviparametersIta shuwa kuti nzvimbo yekuwedzera inogona kuenderana nezvinodiwa chaizvo zvevashandi vakasiyana-siyana vekuchera madryer.
Nekugadzirwa kwayo kwechimiro chinochinjika uye hunhu hwayo hwakanaka, CDSR expansion joint haingovimbisi chete kubatana kwakasimba pakati pepombi nepombi, asiwo inovandudza kuchengetedzeka nekugadzirisa michina.. Nekuda kweizvi, majoini ekuwedzera eCDSR anovimbwa zvikuru uye anoshandiswa zvakanyanya nevashandisi vari munyika nekunze kwenyika.
