PE Mvura Pipe uye Kubatanidza Technology

Nekukwidziridza kwemaguta uye nekusimudzira kwekuziva nezvekuchengetedzwa kwezvakatipoteredza, PE (polyethylene) pombi dzemvura zvishoma nezvishoma zvakatsiva zvechinyakare simbi nePVC pombi sechinhu chinofarirwa chekupa mvura, gasi, madiridziro ekurima nemimwe minda nekuda kwehuremu hwawo, isingadziviriri uye inochengetedza nharaunda. Zvisinei, PE pombi kuita mabhenefiti anogona kuzadzikiswa zvizere, kiyi iri mune chaiyo yekubatanidza tekinoroji.

1, PE pombi yemvura: zvinhu zvenyama uye zvakakosha zvakanakira

1.1 Chii chinonzi PE mvura pombi?  

PE (Polyethylene) inonzi thermoplastic resin, maererano ne density yakakamurwa kuva HDPE (high-density polyethylene) uye LDPE (yakaderera-density polyethylene). HDPE inoshandiswa zvakanyanya mukumanikidza pombi nekuda kwesimba rayo rakakura, kushoma tembiricha kuramba (-60 °C kusvika 60 °C) maitiro; LDPE yemamiriro epasi-kudzvinyirira, semadiridziro edrip irrigation.

1.2 Zvishanu zvakanakira zvePE mvura pombi

Strong corrosion resistance: inopedza zvachose matambudziko emarara uye kuora kwepombi dzesimbi, nehupenyu hwesevhisi kusvika 50 makore.  

Flexible uye inopesana nemhedzisiro: inogona kukotama uye kuiswa kuti ienderane nenzvimbo yakaoma, yakanakisa seismic kuita.  

Utano nekuchengetedzwa kwezvakatipoteredza: non-chepfu, isina hwema, maererano nemitemo yemvura yekunwa, low-carbon production process.  

Huremu uye nyore kuisa: uremu chete 1/8 wepombi yesimbi, kufambisa uye kushanda kwekuvaka kunovandudzwa zvikuru.  

Kuderera kwekuyerera kwekudzivirira uye kuchengetedza simba: rusvingo rwemukati rwakatsetseka, hazvisi nyore kuyera kushandiswa kwenguva refu, kuderedza kupomba kushandiswa kwesimba.

2, PE pombi yekubatanidza tekinoroji: 3 nzira huru

2.1 Hot melt yekubatanidza nzira (inonyanya kushandiswa)  

Principle: nekudziisa iyo PE pombi kupera kumeso kunyunguduka, yakamanikidzwa fusion mune imwe, kugadzira chisimbiso chechigarire.  

Chiitiko chinoshanda: dhayamita ≥ 63mm pombi, kunyanya yakakodzera purojekiti yekuvigwa kwepasi pevhu.  

Operation matanho:  

1. Kucheka kurongeka: shandisa yakakosha pombi yekucheka kuti uone kuti chikamu chemuchinjiko chakati sandara uye chisina burr.  

2. kupisa ndiro preheating: isa tembiricha kuti 210 ± 10 ℃, nguva yekupisa inogadziriswa maererano nehupamhi hwepombi (akadai seDN110 pombi inotora nezve 45 seconds).  

3. fusion pressure: kurumidza kubvisa ndiro inopisa, shandisa 0.15MPa kudzvanywa kuita kuti migumo miviri yedara rakanyungudutswa risanganiswe.  

4. Kutonhodza uye kuumba: chengeta kudzvanywa uye kutonhorera pasi kusvika pazasi 40 ℃ kudzivirira deformation yeiyo interface.  

Kuchenjerera:  

Wedzera nguva yekudziya kana ambient tembiricha yakadzikira pane 5 ℃.  

Rambidza mvura kana jira rakanyorova kuti rikurumidze kutonhora kudzivirira kutsemuka.  

2.2 Electrofusion yekubatanidza nzira (chaiyo uye inoshanda)  

Principle: Shandisa mapombi ekuisa newaya yakavakirwa-mukati kugadzira kupisa, nyungudutsa pombi yePE uye madziro emukati epombi mafita kuti uone kubatana kusina musono.  

Zviratidziro zvinoshanda: nhete nzvimbo kushanda kana kugadzirisa, yakakodzera DN20-DN315 pombi dhayamita.  

Operation process:  

1. kurapwa kwepamusoro: bvisa iyo oxidized layer iri kumagumo kwepombi womaka kudzika kwekupinza.  

2. Kusangana kwepipe fittings: Pinza pombi muhari ye electrofusion kumutsara wekumaka. 3.  

3. Energized fusion: isa voltage uye nguva maererano nekodhi yepiipi fittings (kazhinji 220V, 3-30 maminitsi).  

4. Natural kutonhora: Usafambisa pombi panguva yekutonhora.  

Advantage:  

High degree of automation, kuderedza kukanganisa kwevanhu.  

Kunyanya akakodzera shanduko yekubatanidza mapaipi emhando dzakasiyana.  

2.3 Mechanical yekubatanidza nzira (inochinjika uye nekukurumidza)  

Principle: Kuiswa chisimbiso chenyama kunoitwa kuburikidza neflanges, simbi nezvimwe zvikamu zvesimbi zvisina kudziyisa.  

Mamiriro ezvinhu anoshanda: mabasa enguva pfupi, mapaipi asina-kudzvanywa kana kuti anowanzo kubviswa zvikamu.  

Mhando dzakajairika:  

Flange kubatana: PE flange musoro uye simbi flange yakabhauswa, inoda kuwedzera kuvhara gasket.  

Clamp connection: Stainless simbi inosunga yekukiya mafittings ane barbs, yakakodzera mapaipi madiki dhayamita.  

Zvakanakira nezvayakaipira:  

Zvakanakira: kumhanya kwekuvaka, inogona kubviswa uye kushandiswa zvakare.  

Zvakaipa: kudzvinyirirwa kwenguva refu kunogona kudonha, vanoda kugara vachichengetwa.  

3, kiyi yehutano hwekubatanidza

3.1 Interface leakage

Chikonzero: nguva yekupisa isina kukwana kana kumanikidzwa kusina kuenzana.  

Countermeasure: Shandisa infrared thermometer kutarisa tembiricha yekusanganiswa uye kuve nechokwadi chekugara uchimanikidza.  

3.2 Pipe Eccentricity

Chikonzero: Kucheka kwepombi hakusi perpendicular kana fixture haina kuenderana.  

Kudzivirira: Shandisa kaviri-sided milling muchina kubata nekuguma chiso, uye shandisa laser positioner kuenzanisa panguva yekuisa.  

3.3 Nhema welding phenomenon

Kuratidzwa: Mabhubhu kana zvisaririra zvekusa-fusion munzvimbo yefusion.  

Kurapa: Cheka uye tengesa zvakare pakarepo, tarisa kuchena uye kugadzikana kwekushisa kweplate yekupisa.  

3.4 Matambudziko Ekuvaka Chando

Dambudziko: Tembiricha yakaderera inotungamira kunguva yekunyungudika kwenguva refu uye kutonhora kwakanyanya.  

Solution: Vakai shedhi yekuchengetedza kupisa, preheat pombi kusvika pamusoro pe10 ℃ uye shandisa yakaderera tembiricha mhando electrofusion fittings.  

4. Nzira yekusarudza PE pombi uye nzira yekubatanidza?  

4.1 Pombi yekusarudza gwara

Pressure level: SDR11 (1.6MPa) inokodzera kuwanikwa kwemvura yemanisipala, SDR17 (0.6MPa) inoshandiswa pakudiridza nedrip.  

Certification standards: kuziva GB/T 13663 chiyero chenyika kana ISO 4427 international certification.  

Kusiyanisa kwemavara: nhema (UV inodzivirira, kushandiswa kwekunze), bhuruu (mvura yekunwa), yero (gasi).  

4.2 Muti wesarudzo wekubatanidza nzira

Yenguva refu yakavigwa inoshanda → inopisa nyungudika yekubatanidza

Zvipinganidzo zvemunzvimbo kana kugadzirisa kwechimbichimbi → kubatanidza electrofusion

Kwenguva pfupi/inodzikisika kudiwa → mekiniki yekubatanidza

5. Maintenance: chakavanzika chekuwedzera hupenyu hwePE mapaipi

1. Kuongorora nguva dzose: tarisa kuchembera kweUV yezvikamu zvakafumurwa uye kuputira iyo yekudzivirira kana zvichidikanwa.  

2. Mazano ekuchenesa: shandisa 0.3MPa yakaderera-kudzvanya mvura yekugezesa kudzivirira yakakwira-kumanikidza pfuti yemvura kukanganisa kumadziro emukati..  

3. Frost crack kudzivirira: wedzera tracer tepi munzvimbo dzinotonhora, kana kushandisa kuvigwa kwakadzika (30masendimita pazasi pepermafrost layer).  

PE mvura pombi uye sainzi yekubatanidza tekinoroji, kumaka huinjiniya hwepombi mune imwe nguva yekushanda kwepamusoro uye kuchengetedza kwezvakatipoteredza. Kana kuri kugadzirisa mvura yemhuri, kana mapurojekiti makuru emanisipala, kugona kusarudzwa kwakaringana uye nzira dzekuvaka dzinowedzera zvakanakira zvePE zvinhu. Nekuzivikanwa kwehungwaru tembiricha yekudzora michina uye otomatiki welding marobhoti, PE pombi yekubatanidza iri kusimukira munzira yekunyatso kunyatso uye kuvimbika. Edza PE pombi mupurojekiti yako inotevera uye unzwe musanganiswa wakakwana wekuvaka kwakanaka uye mabhenefiti anogara kwenguva refu!
