Zvinhu zveCable zveKuvhara Mvura
Zvinhu zvinovhara mvura zvinogona kukamurwa kuita mapoka maviri: zvinovhara mvura zvinoshingaira uye zvinovhara mvura zvisingachinji. Zvinovhara mvura zvinoshandisa hunhu hwezvinhu zvinoshandisa mvura uye zvinozvimba. Kana sheath kana joint zvakuvara, zvinhu izvi zvinokura kana zvasangana nemvura, zvichideredza kupinda kwayo mukati metambo. Zvinhu zvakadaro zvinosanganisiragel rinokura rinonwisa mvura, tepi inovhara mvura, upfu hunovhara mvura,shinda inovhara mvura, uye tambo inovhara mvura. Kuvhara mvura kusingapindi mvura, kune rumwe rutivi, kunoshandisa zvinhu zvisingapindi mvura kudzivirira mvura kunze kwetambo kana sheath yakuvara. Mienzaniso yezvinhu zvinovhara mvura zvisingapindi mvura ipaste yakazadzwa nepetroleum, glue inonyunguduka inopisa, uye paste inowedzera kupisa.
I. Zvinhu Zvinodzivirira Mvura Zvisingapindi
Kuzadza zvinhu zvinodzivirira mvura zvisina simba, zvakaita sepetroleum paste, mutambo ndiyo yaive nzira huru yekuvhara mvura mutambo dzemagetsi dzepakutanga. Nzira iyi inodzivirira mvura kupinda mutambo asi ine zvipingamupinyi zvinotevera:
1.Inowedzera zvakanyanya huremu hwetambo;
2. Zvinokonzera kudzikira kwekushanda kwetambo yekufambisa magetsi;
3. Petroleum paste inosvibisa zvakanyanya majoini etambo, zvichiita kuti kuchenesa kuome;
4. Maitiro ekuzadza zvizere akaoma kudzora, uye kuzadza kusina kukwana kunogona kukonzera kusashanda zvakanaka kwekudzivirira mvura.
II. Zvinhu Zvinodzivirira Mvura Zvinoshanda
Parizvino, zvinhu zvinodzivirira mvura zvinoshandiswa mutambo zvinonyanya kuva tepi inovhara mvura, upfu hunovhara mvura, tambo inovhara mvura, uye shinda inovhara mvura. Zvichienzaniswa nepetroleum paste, zvinhu zvinodzivirira mvura zvine hunhu hunotevera: kunyudzwa kwemvura kwakanyanya uye kuzvimba kwakanyanya. Zvinogona kunyudzwa mvura nekukurumidza uye kuzvimba nekukurumidza kuti zvigadzire chinhu chakaita sejeri chinovhara kupinda kwemvura, nokudaro zvichiita kuti tambo irambe yakachengeteka. Pamusoro pezvo, zvinhu zvinodzivirira mvura zvinoreruka, zvakachena, uye zviri nyore kuisa nekubatanidza. Zvisinei, zvine zvimwe zvinokanganisa:
1. Hupfu hunovhara mvura hunonetsa kubatanidza zvakaenzana;
2. Tepi kana shinda inovhara mvura inogona kuwedzera dhayamita yekunze, ichikanganisa kupisa, ichikurumidzisa kukwegura kwetambo, uye ichideredza kugona kwetambo kutumira;
3. Zvinhu zvinodzivirira mvura zvinoshanda zvinowanzo kudhura.
Kuongorora Kuvhara Mvura: Parizvino, nzira huru muChina yekudzivirira mvura kuti isapinde muchikamu chekudzivirira kupisa kwetambo ndeyekuwedzera chikamu chekudzivirira mvura. Zvisinei, kuti tiwane kuvharwa kwakazara kwemvura mutambo, hatifanirwe kungofunga nezvekupinda kwemvura neradial chete asiwo kudzivirira kupararira kwemvura kwenguva refu kana yapinda mutambo.
Polyethylene (Inner Sheath) Waterproof Isolation Layer: Kuburitsa polyethylene-blocking water layer, pamwe chete ne cushion-capture layer (yakadai se water-blocking tape), kunogona kusangana nezvinodiwa zve longitudinal water blocking uye hunyoro mu tambo dzakaiswa munzvimbo dzine hunyoro hune mwero. Polyethylene-blocking water layer iri nyore kugadzira uye haidi mimwe michina.
Tape yeAluminium Yakaputirwa nePlastiki Polyethylene Bonded Waterproof Isolation Layer: Kana tambo dzakaiswa mumvura kana munzvimbo dzakanyorova zvakanyanya, simba rekudzivirira mvura re polyethylene isolation layers rinogona kunge risina kukwana. Kune tambo dzinoda kushanda kwakawanda kwekudzivirira mvura, zvakajairika kuputira tambo yealuminium-plastic composite tape yakatenderedza tambo. Chisimbiso ichi chinodzivirira mvura kakapetwa mazana kana kunyange zviuru kupfuura polyethylene yakachena. Chero bedzi musono wetepi yecomposite wakabatana zvizere uye wakavharwa, kupinda kwemvura kunenge kusingagoneki. Tape yealuminium-plastic composite inoda nzira yekuputira nekubatanidza kwenguva refu, iyo inosanganisira kuwedzera mari uye kugadziriswa kwemidziyo.
Mukuita kweinjiniya, kuvharira mvura kwenguva refu kwakaoma kupfuura kuvharira mvura ine radial. Nzira dzakasiyana-siyana, dzakadai sekushandura chimiro chemuchina wekufambisa mvura kuita dhizaini yakadzvanywa zvakasimba, dzakashandiswa, asi mhedzisiro yacho yave shoma nekuti kuchine mipata iri mumuchina wekufambisa mvura unobvumira mvura kupararira kuburikidza nekuita kwe capillary. Kuti uwane kuvharira kwechokwadi kwemuchina wekufambisa mvura kwenguva refu, zvakakosha kuzadza mipata iri mumuchina wekufambisa mvura nezvinhu zvinovhara mvura. Matanho maviri anotevera ekuyeresa uye maumbirwo anogona kushandiswa kuvharira mvura kwenguva refu mutambo:
1. Kushandisa madhaivha anovhara mvura. Wedzera tambo inovhara mvura, upfu hunovhara mvura, shinda inovhara mvura, kana kuputira tepi inovhara mvura yakatenderedza dhaivha inodzvanywa zvakasimba.
2.Kushandisa macore anovhara mvura. Munguva yekugadzira tambo, zadza core neshinda inovhara mvura, tambo, kana kuputira core netepi inovhara mvura inopinza kana inodzivira mvura.
Parizvino, dambudziko guru mukuvhara mvura kwenguva refu riri mumakondirakita anovhara mvura—kuti angazadza sei zvinhu zvinovhara mvura pakati pemakondirakita uye kuti ndeapi zvinhu zvinovhara mvura zvekushandisa zvichiri kutsvagurudzwa.
Ⅲ. Mhedziso
Tekinoroji yekudzivirira mvura yeradial inonyanya kushandisa machira ekudzivirira mvura akaputirwa padanho rekudzivirira dhayamita, nechikamu checushion chinotora hunyoro chakawedzerwa kunze. Kune tambo dzemagetsi ari pakati nepakati, tepi yealuminium-plastic composite inowanzo shandiswa, nepo tambo dzemagetsi ane simba guru dzichiwanzo shandisa majaketi esimbi esimbi ane lead, aruminiyamu, kana stainless steel sealing.
Tekinoroji yekudzivirira mvura kwenguva refu inonyanya kutarisisa kuzadza mipata iri pakati petambo dzinofambisa mvura nezvinhu zvinovhara mvura kuti zvivhare kupararira kwemvura pakati pemvura. Kubva pakuvandudzwa kwetekinoroji iripo, kuzadza neupfu hunovhara mvura kunoshanda zvakanyanya pakuvhara mvura kwenguva refu.
Kuwana tambo dzisingapindi mvura kunokanganisa kupisa kwetambo uye mashandiro ayo ekufambisa mvura, saka zvakakosha kusarudza kana kugadzira chimiro chakakodzera chetambo inovhara mvura zvichienderana nezvinodiwa zveinjiniya.
