Impendulo esheshayo
Ani-accumulator blow umshini wokubumbaizitolo zepulasitiki ezincibilikisiwe kusilinda ngemva kwekhanda lefasi bese ziyiphusha njengesonto elilodwa elikhulu - elakhelwe izingxenye ezisindayo njengezigubhu, amathangi e-IBC, nanoma yini edlule cishe amalitha angama-30. Aumshini wokubumba oqhubekayoigcina isonto ligeleza ngokungami futhi lifanelana nemikhiqizo emincane, enevolumu ephezulu njengamabhodlela namathini amajeri afinyelela ku-15 litres. Isici esinqumayo sangempela yi-parison sag. Phansi kwethu, imishini yokuthutha eqhubekayo ihlanganisa cishe u-0.1-15 L; uchungechunge lwe-accumulator (njenge-KGB80A) lusebenzisa amathangi angu-30 L kufika ku-1000 L IBC.
Abantu basibuza lokhu njalo: "Ingabe ngidinga umshini wokuhlanganisa, noma ingabe oqhubekayo uzowenza umsebenzi?" Kuzwakala njengombuzo omncane. Akunjalo. Khetha okungalungile bese ukhokha ngokweqile ngomshini ovala umthamo wawo omningi, noma uthenga into engakwazi ukwenza ingxenye oyithengisayo. Zombili ziyenzeka. Sibone sobabili singena emnyango wethu.
Ngakho-ke nansi inguqulo ethembekile, ngendlela efanayo ebesingayichazela ngayo ikhasimende emi phansi efekthri. Ayikho i-fluff, ukuthi le mishini yomibili iziphatha kanjani nokuthi ngamunye uhola kuphi.
Umehluko wangempela ukuthi isonto lenziwa kanjani
Yomibili imindeni yemishini yenza i-extrusion blow molding. Zombili zincibilikisa ipulasitiki, zenze ishubhu elingenalutho elibizwa ngokuthi i-parison, zibophe isikhunta nxazonke zazo, futhi zivuthele ngomoya ezindongeni zesikhunta. Leyo ngxenye iyafana. Umehluko uhlezi endaweni eyodwa: ifa ikhanda, nokuthi liletha kanjani ijele.
I-extrusion eqhubekayo, ngamagama alula
I-extruder igijima ngaphandle kokuma. Ipulasitiki igeleza ekhanda likadayizi iphumele phansi njengepharishi eqhubekayo, ilenga phansi njengomuthi wokuxubha ukhanywe eshubhuni elingayeki ukuphakama. Ngenxa yokuthi i-parison ilokhu iza, isikhunta kufanele sinyakaze - siyangena, sibambe, futhi siphume ngenkathi isonto elilandelayo selivele liyakha. Yingakho uzobona lezi zithengiswa njengemishini yesiteshi esisodwa kanye ne-double station. Isiteshi esiphindwe kabili simane sisho iziteshi zesikhunta ezimbili ezabelana ngekhanda elilodwa lokufa, ngakho uhlangothi olulodwa luyaphephetha ngenkathi olunye lukhipha. Ukuphuma okwengeziwe okuvela ku-extruder efanayo.
Lokhu kusetha kuyashesha futhi konga ezingxenyeni ezincane. Eyethu2L umshini wesiteshi esiphindwe kabiliisisindo esingamathani angu-4.5; i5L isiteshi esiphindwe kabilicishe amathani angu-5.2. Iqinile, ibhayisikili elisheshayo, nokugijima okujabulisayo usuku lonke emabhodleleni.
Ikhanda le-accumulator, ngamagama alula
Manje phendula i-logic. Esikhundleni sokuvumela upulasitiki uphume ngokuqhubekayo, umshini wokuqoqa uqoqa inyibiliki kusilinda yokugcina ehlezi ngemuva kwefasi - izincwadi zomkhiqizo we-Kinggle zikubiza ngokuthi "uchungechunge lwekhanda le-cylinder die head." Ukuncibilika kuyakha. Bese kuthi inqama ikhiphe yonke inkokhiso ngokuphusha okukodwa okusheshayo, yenze isonto elikhulu emizuzwaneni embalwa ngaphambi kokuba amandla adonsela phansi abe nethuba lokuyonakalisa.
Lelo jubane yilona phuzu, futhi yingakho zonke iziqukathi ezinkulu kulayini wethu - 30 L, 60 L, 120 L, 160 L, 250 L, kuze kufike lapho1000 L IBC tank umshini— isebenzisa inhloko ye-accumulator. Awukwazi ukwenza lezo zingxenye nganoma iyiphi enye indlela futhi ugcine izindonga zilingana.
Kungani i-parson sag iyisici esinqumayo ngempela
Nakhu ukweqa okuncane kakhulu kwamashidi. Isonto liyipulasitiki encibilikisiwe, futhi ipulasitiki encibilikisiwe ilenga ngaphansi kwesisindo sayo. Ebhodleleni elincane, i-parison ifushane futhi ilula, ngakho-ke akunandaba - lisesikhunjeni ngaphambi kokuthi kube khona okungahambi kahle. Kodwa yenza lelo sonto libe likhulu futhi libe nzima, futhi i-physics ithatha izintambo. Ingaphezulu, elibambe yonke into engezansi kwalo, liyanwebeka futhi lizacile. Ngesikhathi isikhunta sivala usuthole ingxenye ezacile kakhulu ehlombe futhi ewugqinsi kakhulu esisekelweni. Ibuthakathaka lapho idinga ukuqina khona.
Lokho kunwebeka kuyi-parison sag, futhi ukuyishaya yisona sizathu sokuba khona kwekhanda le-accumulator. Ngokugcina isibhamu nokuyidubula ngokushesha, i-accumulator ithola i-parison enkulu esikhunjeni ngaphambi kokuba ibe nesikhathi sokuwa. Ukufa okuqhubekayo akukwazi nje ukuphusha ipulasitiki engaka ngokushesha - isonto lalilenga lapho lixega ngenkathi i-extruder ibamba kancane kancane.
Ngakho umbuzo othi "i-accumulator noma eqhubekayo?" Ingabe ngempela umbuzo othi "ingabe i-parison yami isindayo ngokwanele ukucwila ngaphambi kokuba isikhunta sivale?" Phendula lokho bese uhlobo lomshini luziphendulela lona.
