Kubatanidza mapaipi kwakakosha, asi kubatana kusina kusimba kunotungamira pakukundikana. Kubatana kweHDPE kunogadzira chisungo chisingaperi, chemonolithic, zvichiita kuti hurongwa hwese huve hwakasimba uye huve nerugare rwepfungwa kwemakumi emakore.

Kubatanidza HDPE kunoshandiswa kubatanidza mapaipi maviri eHDPE. Kuburikidza nekubatana kwekupisa, kunoita kuti pave nekubatana kunoramba kuripo, kusingadonhedze mvura, kwakasimba sepaipi pachayo. Izvi zvinobvisa kushaya simba kwemuchina uye zvinoita kuti pave nekuvimbika kwenguva refu mukushandiswa kwakavanzika kana kwakakosha.

Ndakaona mapurojekiti asingaverengeki achibudirira kana kukundikana zvichibva pachinhu chimwe chete: kunaka kwejoini. Mumakore angu gumi nemasere semugadziri, ndakadzidza kuti pombi ingori chubhu, asi nzvimbo yekubatanidza ndiyo inonyanya kukosha pakugadzira uye mhando.Kubatanidza kweHDPEhaisi kungobatanidza chete; ivimbiso yehurongwa husina musono. Izvi zvinonyanya kuitika munzvimbo dzinoda mvura yakawanda sedziri muIndonesia, uko kutarisirwa kwemvura kwakavimbika kwakakosha. Ngatitarisei kuti kubatana uku kunoitwa sei uye kuti nei kuri nani pane nzira dzechinyakare.

Ungabatanidza sei HDPE neHDPE?

Kubatanidza mapombi eHDPE kunogona kuita sekunge kwakaoma. Kushandisa nzira isiriyo kunogona kugadzira nzvimbo isina kusimba iyo inokundikana kana paine kumanikidzwa. Kubatanidza kupisa ndiyo chete nzira yekubatanidza zvechokwadi.

Unobatanidza HDPE kuHDPE uchishandisa nzira dzekubatanidza kupisa. Dzakajairika ndeyekubatanidza mabutt emapaipi makuru, kubatanidza socket yemapaipi madiki, uye kubatanidza electromagnetic yekugadzirisa. Maitiro aya anonyungudutsa pamusoro pepurasitiki pamwe chete, zvichiita kuti pave nejoini rimwe chete, rakasimba, uye risingadonhe mvura zvachose kana ratonhodzwa.

Pfungwa huru yekubatanidza HDPE haisi yekungoibatanidza chete, asi kuibatanidza. Tiri kugadzira zvidimbu zviviri zvakasiyana kuita chimwe chete. Kusiyana nePVC inoshandisa guruu kana mapaipi esimbi anoshandisa shinda, HDPE inoshandisa hunhu hwayo hwethermoplastic kuti ibudirire. Nekushandisa kupisa kwakadzorwa, tinounza chinhu chacho panzvimbo yacho yekunyunguduka. Kana chanyunguduka, cheni dzepolymer kubva papombi nepachinosungirirwa dzinosanganiswa zvakasununguka. Sezvatinoisa kumanikidzwa torega kuchitonhora, cheni idzi dzinobatana uye dzinosimba, zvichigadzira chisungo chakasimba, kana chisina kusimba, kupfuura rusvingo rwepombi rwepakutanga. Izvi ndizvo zvatinodaidza kuti monolithic system—zvinoita sekunge pombi yese yakagadzirwa nepurasitiki imwe chete kubva pakutanga. Izvi zvinobvisa chero nzira inogona kudonha, dambudziko randinowanzo kunzwa kubva kumainjiniya anotarisira zvivakwa zvemvura zvakakosha.

Kugadzira Sisitimu yeMonolithic

Ndeipi mhando yakazara yeHDPE?

Tinoshandisa mazwi mapfupi eindasitiri zuva nezuva tisingafungi kaviri. Asi kusaziva zvinorehwa neHDPE kunogona kuvanza hunhu hwayo hwakanakisisa. Kunzwisisa zita rayo kunoratidza kuti nei iri chinhu chepamusoro.

HDPE inomiririra High-Density Polyethylene. Ipolymer yethermoplastic inozivikanwa nehukuru hwayo hwesimba-kusvika-kuwanda. Chimiro ichi che "High-Density" ndicho chinoita kuti pombi irambe yakasimba, isingapindike nemakemikari, uye igare kwenguva refu, zvichiita kuti ive yakakwana kumapurojekiti ezvivakwa anoda simba.

Ngatitsanangure zita racho, nekuti rinokuudza zvese zvaunoda kuziva. "Polyethylene" zvinoreva chimiro chepolymer chikuru—cheni refu dzemamorekuru e-ethylene. Ipurasitiki iri nyore uye yakagadzikana. Chikamu chikuru i "High-Density". Munguva yekugadzira, tinogadzira idzi cheni dzepolymer nematavi mashoma kwazvoIzvi zvinovabvumira kuungana pamwe chete, zvichigadzira chimiro chakasimba, chakajeka. Kuwanda uku kwakanyanya ndiko kunokonzera zvakananga kunaka kwezvinhu zvakagadzirwa: kuomarara kwazvo, simba razvo, uyekuramba kwakanaka kwemakemikari uye kukweshaSemugadziri, tinonyanya kushanda nePE100, giredhi repamusoro reHDPE. Kana ukaienzanisa nezvimwe zvinhu, zvakanakira zvayo zvinova pachena.

Zvinotaurwa Nezita Racho

Ko HDPE ine majoini here?

Mumapaipi echinyakare, majoini ndiwo anokonzera kubuda kwemvura nekukundikana. Izvi zvinogara zvichikonzera kunetseka. Nekusanganiswa kweHDPE, kushaya simba uku kwechinyakare kunonyangarika.

Kwete, sisitimu yeHDPE yakanyatsobatanidzwa haina majoini nenzira yechinyakare. Maitiro ekubatanidza kupisa anogadzira pombi imwe chete. Nzvimbo yekubatanidza inova purasitiki inoenderera mberi ine simba uye kuvimbika kwakafanana nemadziro epombi pachawo.

Mubvunzo uyu unosvika pamwoyo wekuti sei HDPE iri kuchinja zvinhu. Vanhu pavanofunga nezve "jointi," vanofungidzira kubatana kwemuchina - gasket, flange ine mabhaudhi, kana shinda yekubatanidza. Idzi dzese inzvimbo apo zvikamu zviviri zvakasiyana zvinomanikidzwa pamwe chete, zvichigadzira nzira inogona kukonzera kubuda kwemvura.HDPE fusion weldzvakasiyana zvachose. Harisi joini; inoramba richienderera mberi. Hakuna magasket ekuparadza, hapana mabhaudhi ekusungazve.

Mumapurojekiti mazhinji ezvivakwa uko mamiriro epasi anogona kusagadzikana, izvi zvinobatsira zvikuru. Pombi yakasimba ine majoini emakanika inodonhedza mvura kana pasi rachinja.pombi inochinjika, ine monolithic HDPEinofamba nepasi, ichichengetedza kunaka kwayo. Inobvisa njodzi huru kubva kune chero chirongwa chepombi yakavigwa.

Kubatsira kweSistimu 'isina Majoini'

Ndedzipi nzira dzekubatanidza HDPE pombi?

Unoziva kuti HDPE inofanira kusanganiswa, asi kune nzira dzakawanda dzekuzviita. Kusarudza nzira isiriyo yebasa kunogona kutambisa nguva nemari, zvichikanganisa kuvimbika kwepurojekiti yako.

Nzira nhatu huru dzekubatanidza mapaipi eHDPE dzese dzakavakirwa pakubatana kwekupisa. Kubatanidza mabutt ndekwemapaipi makuru (63mm+), kusanganisa masoketi ndekwemapaipi madiki (anosvika 110mm), uye kusanganisa magetsi kwakanakira kugadzirisa, kubatana, uye mamiriro ezvinhu apo dzimwe nzira dzisiri dzekushandisa.

Kunyange zvazvo nzira dzese dzichishandisa kupisa, dzakagadzirirwa mamiriro akasiyana.Kusanganiswa kwemagarondiyo nzira inoshanda zvikuru pakuvaka zvivakwa zvikuru. Izvi zvinosanganisira kutarisa magumo emapaipi, kudziisa mundiro, uye kudzibatanidza pamwe chete kuti dzigadzire weld.

Kune dhayamita diki,Kusanganiswa kwemasokisiZvinokurumidza uye zviri nyore. Pano, tinodziisa kunze kwepombi nemukati mesokisi re fitting panguva imwe chete tisati tazvisundira pamwe chete.

Pakupedzisira, paneKusanganiswa kweElectromagnetic. Zvishandiso izvi zvine ma "heating coils" akavakirwa mukati. Unoisa "fitting" pamusoro pemapaipi, woibatanidza kune simba remagetsi, uye ma "coils" anonyungudutsa purasitiki kubva mukati kuenda kunze.

Kunewo michina yekuisa zvinhu, asi izvi zvinonyanya kushandiswa pakuchinja kuenda kune zvimwe zvinhu zvepombi kana kuti pakugadzirisa kwenguva pfupi, kwete pakugadzira pombi yekutanga, inogara iripo.
