Nei tichifanira kusarudza PPH vharafu, pombi fitting kana pombi

PPH valve imhando yevharuvhu yakagadzirwa nepolypropylene (PP) zvinhu, ine hunhu hwekureruka, kugadzirisa nyore, kuchinjika kwakanaka uye zvichingodaro, saka kune zvakawanda zvinoshandiswa mukugadzira uye hupenyu. Zvinotevera ndezvimwe zvinonyanya kushandiswa:

Indasitiri yemakemikari:

Muindasitiri yemakemikari, PPH mavharuvhu anoshandiswa zvakanyanya mukutonga kwepombi yeakasiyana siyana anoodza media, akadai seasidhi, alkali, munyu uye zvichingodaro. Nekuda kwekushomeka kwayo kwegora uye yakasimba anti-kuchembera zvivakwa, PPH mavharuvhu anogona kushanda akadzikama kwenguva yakareba, izvo zvinonyatso chengetedza kuchengetedzwa uye kugadzikana kwekugadzirwa kwemakemikari.

Indasitiri yekuchenesa mvura:

PPH mavharuvhu anoshandiswawo zvakanyanya mumunda wekucheneswa kwemvura uye kurapwa kwetsvina. Nekuda kwekuita kwayo kwakanakisa kwehutsanana, haina zvinhu zvine chepfu, mavharuvhu ePPH mukugadzirisa kwemvura haaburitse kusvibiswa kwechipiri kwemhando yemvura, saka muindasitiri yekurapa mvura inofarirwa zvakanyanya.

Indasitiri yechikafu:

Muindasitiri yechikafu, mavharuvhu ePPH anoshandiswa zvakanyanya mukugadzira chikafu uye kurongedza maitiro nekuda kweasina-chepfu, asinganhuhwi uye anodzivirira marara. Semuenzaniso, mukugadzirwa kwezvinwiwa, mavharuvhu ePPH anogona kushandiswa kudzora kuyerera uye kutungamira kwekuyerera kwezvinwiwa; mukurongedza chikafu, PPH mavharuvhu anogona kushandiswa kudzora vacuum masisitimu uye pneumatic masisitimu.

Pharmaceutical industry:

Muindasitiri yemishonga, mavharuvhu ePPH anoshandiswa zvakanyanya mukugadzira, kuchengetedza uye kutakura kwemishonga nekuda kwehutsanana hwayo hwepamusoro uye kusagadzikana kwekuora. Semuenzaniso, mavharuvhu ePPH anogona kushandiswa kudzora mafambiro ekuyerera uye kuyerera kwehuwandu hwemishonga panguva yekuzadza; mukuchengetedza mishonga, mavharuvhu ePPH anogona kushandiswa kudzora hunyoro uye tembiricha yeimba yekuchengetera zvinhu.

Pamusika, pane UPVC, CPVC, PPH, PVDF, FRPP vharafu, uye pombi system. Chikonzero chinotevera nei tichifanira kusarudza PPH vharafu, pombi yekuisa kana pombi?

Chii Chimiro chePPH zvinhu?

Polypropylene Homopolymer (PP-H) imwe mhando yePP. Iyo ine tembiricha iri nani & inokambaira kuramba pane PPR, uye ine yakaderera tembiricha simba rekuita.

Parizvino PPH mapaipi & mafittings anonyanya kuvimbika mumapombi epombi uye ekupa mvura zvidyarwa, nekuda kwemakemikari maficha uye fusion welding, iyo inovimbisa kuti pombi yepombi kuve neyakakwana chisimbiso yakasimba system. Yakatenderwa neHealth Organisation ine hunhu hwakadai seEco-hushamwari uye yakanyanya tembiricha kuramba, PPH/PPR mapaipi & mafittings akatorwa seimwe yeakanakisa mhinduro yemapombi masisitimu.

Tembiricha yepamusoro yePPH mapaipi i110 ℃, uye inowanzo shandiswa pazasi 90 ℃. Iwo anoshandisirwa kutonhora kutamisa mvura, corrosive material transfer, fume ducts, electrolyze systems, uye mamwe mapombi masisitimu ane acid zvinwiwa.

Chii chinonzi PPH Physical Properties?

Chii chinonzi PPH zvigadzirwa zvekubatanidza nzira?

PPH pombi system inosungirirwa nekupisa kunyunguduka, iyo inogona kukamurwa kuita inopisa melt socket welding uye inopisa melt butt welding. Iwo chaiwo matanho ekupisa melt socket welding ndeaya anotevera:

Tungamira mapaipi mumudziyo wakananga kuhupamhi hwegungano. Zvichakadaro, sundidzira fitting pane hita uye usvike pakadzika yakadzama.

Tungamira mapaipi mumudziyo wakananga kuhupamhi hwegungano. Zvichakadaro, sundidzira fitting pane hita uye usvike pakadzika yakadzama.

Nguva yekupisa inofanira kutevedzerwa nehunhu huri patafura yepasi (peji rinotevera). Mushure menguva yekupisa, bvisa pombi uye kuisa kubva kune hita nekukasira uye uzviunganidze kune yakadzama yakadzama yakatwasuka kuitira kuti pave nebulge inzvimbo yegungano. Mukati menguva yekushanda, kugadziridzwa kudiki kunogona kuitwa asi kutenderera kunofanira kurambidzwa. Kuchengeta pombi nekukochekera kubva pakukweshwa, kukotama, nekutambanudzwa.

Kana tembiricha yenzvimbo yakadzikira pane 5 ℃, wedzera nguva yekudziya ne50%

Kana uchibatanidza, isa mativi ewelding pasimbi inopisa kusvika mativi ese akazara kubata simbi inopisa zvachose, kudivi nedivi, uye inogona kucherechedza kuumbwa kweflanging. Kana iyo flanging kureba yakatenderedza yese denderedzwa yechubhu kana iyo yese yepamusoro yeplate inosvika kukosha kunodiwa, ipapo inowirirana.

Mushure mekupisa kunopisa kunyunguduka butt welding, chinongedzo chinozogadziriswa muchina unopisa unonyungudika butt welding muchina, uye kutonhorera chinongedzo zvinoenderana nenguva yekutonhora iyo inotsanangurwa mumirau yekumanikidza kuchengetedza uye kutonhora kweanopisa melt butt welding muchina. Mushure mekutonhora, dzikisa kumanikidza kusvika zero, uye wozobvisa welded pombi/fittings.

Kupisa kunyunguduka butt welding process referensi tafura yePPH mapaipi uye mafittings
