Ukuhlukaniswa kwebhande lokunisela ngamaconsi kanye nokwethulwa kwemishini

Amabhande okunisela ngamaconsi okwamanje kuyindlela ephumelela kakhulu yokunisela okonga amanzi ezindaweni ezomile nezingenamanzi, ngesilinganiso sokusetshenziswa kwamanzi esifinyelela ku-95%. Ukunisela ngokuconsa kunokonga amanzi okuphezulu futhi kukhulisa isivuno kunokufaka umquba, futhi kungahlanganiswa nokusetshenziswa komanyolo ukuze kuthuthukiswe ukusebenza kahle komanyolo ngokuphindwe kabili. Kungasetshenziswa ezihlahleni zezithelo, imifino, izitshalo ezithengiswayo kanye nokunisela okushisa ukushisa, futhi kungasetshenziswa nasekuniseleni izitshalo zasensimini ezindaweni ezomile nezingenamanzi.

Itheyiphu yokunisela ngokuconsa ithuthuka ngokushesha kubuchwepheshe bethu bokunisela ngokuconsa, ngakho-ke kubaluleke kakhulu ukwazi ngetheyiphu yokunisela ngokuconsa.

Itheyiphu yokunisela ngamaconsi iwukusetshenziswa kwepayipi lepulasitiki (ipayipi lokunisela ngamaconsi) isiteshi sizoba namanzi ngokusebenzisa ububanzi obungu-10mm we-capillary noma ikhanda lokunisela emaceleni omgodi kuya ezimpandeni zezitshalo ukuze kuniselwe endaweni. Kungokusebenzisa i-orefice yokuphuma encane kakhulu ekhanda lokunisela noma etheyiphu yokunisela ngamaconsi, amanzi awela kancane kancane futhi awela kancane kancane enhlabathini eduze kwezimpande zezitshalo.

Amathephu okunisela ngokucwilisa ahlukaniswe ngamathephu okunisela ngoketshezi oluyi-patch, amashubhu okunisela ngoketshezi oluyi-cylindrical, amathephu okunisela ngoketshezi oluyi-labyrinth, kanye namathephu okunisela ngoketshezi oluyi-blue track.

Izici zetheyiphu yokunisela nge-patch drip irrigation

● Ikhanda elingaphakathi elinomnyango wokuhlunga, ukusebenza kahle kokuvimbela ukuvaleka.

● Umklamo womgijimi wokugeleza oguquguqukayo. Ukunisela okufanayo.

● Ukuqina okuqinile kwekhanda lokuconsa kanye nepayipi.

● Ukulungiswa okuguquguqukayo kwesikhala sekhanda lokuconsa, ububanzi besicelo.

Imishini yokukhiqiza itheyiphu yokunisela ngamaconsi isetshenziswa kakhulu i-extruder yesikulufu esisodwa (umshini oyinhloko), imishini yokusiza kanye nama-winder. Isakhiwo esiyisisekelo se-extruder ene-screw eyodwa yile: idivayisi yokudlulisela, idivayisi yokondla, i-barrel, i-screw, ikhanda kanye ne-diye kanye nezinye izingxenye ezinhlanu.

Idivayisi yokudlulisa. Okusho ukuthi, ingxenye yokushayela ye-screw drive, ngokuvamile yi-motor, i-reducer mechanism kanye nama-bearings, njll., enqubweni yokukhipha ezinzile, isivinini sesikulufu kumele sigcinwe ezingeni elifanayo ukuvimbela ukuguquguquka kwenani lokukhipha, ukuze kuhlangatshezwane nezidingo zokukhiqiza ezahlukene, isikulufu kufanele siqhutshwe ngesivinini esiguquguqukayo, idivayisi yokudlulisa ye-extruder ngokuvamile isetshenziswa ngesivinini esiguquguqukayo esingenasinyathelo.

Idivayisi yokugcwalisa. Idivayisi yokushaja ngokuvamile isebenzisa i-hopper yokushaja eyindilinga, enejakethi yamanzi apholile ezungeze imbobo yokushaja ukuze isuse ukushisa kusuka emgqonyeni wokushisa okuphezulu kuya ku-hopper ukuze kuvinjelwe ipulasitiki ukuthi ingashisi embobeni yokushaja kanye nokubopha, okuholela ekushajeni okungalingani noma ukugeleza kwezinto ezivinjiwe.

I-Barrel ingenye yezingxenye eziyinhloko ze-extruder, izinqubo ze-plasticizing kanye ne-pressurizing zenziwa kuyo, ingcindezi engaphakathi kwe-barrel ngesikhathi sokukhipha ingafinyelela ku-30 ​​~ 50Mpa, izinga lokushisa ngokuvamile liyi-150 ~ 300℃, futhi kukhona amadivayisi okushisa nokupholisa ahlukanisiwe ngaphakathi kwe-barrel.

Isikulufu siyingxenye ebalulekile ye-extruder, ngenxa yokujikeleza kwesikulufu, umgqomo wepulasitiki ukuze ushukumise, uthole ingcindezi kanye nengxenye yokushisa, amapharamitha ejiyometri yesikulufu anethonya elikhulu ekusebenzeni kwesikulufu, amapharamitha ayinhloko esikulufu: ububanzi besikulufu, isilinganiso sesici, isilinganiso sokucindezela, njll., futhi manje isikulufu se-extruder sokunisela ngokucwilisa singobubanzi obungu-40, 50mm, isilinganiso sesici esingaba ngu-30: 1~40: 1.

Isikhunta sekhanda nomlomo. Ikhanda yingxenye enkulu phakathi kwesikhunta somlomo nomgqomo, kanti isikhunta somlomo yingxenye eyakha ingxenye yomkhiqizo, eqiniswe ekhanda ngamabhawodi noma ezinye izindlela. Ukuthi ikhanda nesikhunta somlomo kuyafaneleka noma cha kunethonya elikhulu ekukhiqizweni nasekhwalithini yemikhiqizo, futhi usayizi unqunywa ngokuya ngolwazi olusebenzayo noma ulwazi lwe-rheological. Imishini yokusiza, imishini yokusiza ikakhulukazi yakha isikhunta, umshini wokudonsa kanye nohlelo lokulawula amapharamitha. Indima yayo eyinhloko ukwakheka komkhiqizo, ukupholisa umkhiqizo, ukulawula amapharamitha omkhiqizo. Umshini wokugoqa, ikakhulukazi womkhiqizo ogoqa imikhiqizo eqediwe, bese uqopha inani lamamitha.

Ipulasitiki esuka ku-hopper iye emgqonyeni, ngokuzungeza kwesikulufu icindezelwa kancane kancane iye ekhanda, engxenyeni yokushaja yezinto ihlanganiswa kancane kancane, lapho izinto zingena esigabeni sokucindezelwa, ngenxa yokungajulile kancane kancane kwezintambo, futhi ngenxa yesibuko somgijimi we-angle yesokudla kanye nomlomo wesikhunta nokunye ukumelana, ukuze izinto zibe nokucindezela okukhulu ekwakhekeni.

Izinto zihlanganiswa kancane kancane, ngesikhathi esifanayo emgqonyeni wokushisa kwangaphandle kanye nesikulufu sangaphakathi kanye nodonga lomgqomo we-shear yokuxuba izinto ekhiqizwa ukushisa kwe-shear, izinga lokushisa lepulasitiki liyakhuphuka kancane kancane, cishe ingxenye yesithathu yesigaba sokucindezela, saqala ukufinyelela izinga lokushisa eliqinile, lapho isiqondiso sokukhipha siya ekhanda, inani lezinto ezincibilikisiwe liyakhuphuka kancane kancane, futhi inani lezinto ezingancibilikisiwe liyancishiswa kancane kancane, cishe ekupheleni kwesigaba sokucindezela, zonke izinto ezincibilikisiwe kanye nesimo se-viscous, kodwa ukuncibilika akuncibilikisi.

Cishe ekupheleni kwesigaba sokucindezela, zonke izinto ziyancibilika bese ziphenduka isimo esiqinile, kodwa ngalesi sikhathi, izinga lokushisa lephuzu ngalinye lisalingana kakhulu. Ngemva kwesigaba sokuxuba somphumela wokuxuba, isikulufu sizoncibilikisa izinto zibe sekhanda ngokucindezela okuqinile, ubuningi kanye nokushisa.

Isikhunta somlomo ekhanda lomshini siyingxenye yokwakha, izinto ezisetshenziswa ngesikhunta somlomo ekhanda lomshini ukwakha ingxenye ethile yesimo nosayizi wejometri, bese zidlula esondweni lokwakha endaweni yokuhlanza, ukupholisa, ukusika nokunye ukuze kutholakale umkhiqizo ophelele.
