Mashandisirwo Anoitwa Simba reMuchina weHydraulic Press Wakajairika

Muchina wekugadzira injini we hydraulic injection molding unoshanda nemota yemagetsi nekumhanya kwakafanana, kazhinji wakabatana zvakananga kumagetsi makuru pasina frequency drive inochinja-chinja. Mota iyi inotyaira pombi ye hydraulic inofambiswa nemota — kazhinji pombi ye vane kana pombi ye axial piston — iyo inopa kuyerera kwakafanana kwe hydraulic fluid pakumanikidzwa kwakaenzana nemutoro. Mavharuvhu ekudzora anotungamira, mavharuvhu anoenzana, uye mavharuvhu e servo anochinja kuyerera nekumanikidzwa kuti zvienderane ne mold close, injection, hold, plasticizing, uye mold open phases dze cycle.

Mota inomhanya nekumhanya kwakazara mukati menguva yese, kunyangwe kana hydraulic demand yakaderera. Munguva yekubata - apo chikamu chinoda chikamu chidiki chepeak flow kuti chirambe chiri mu cavity pressure - kuwanda kwemvura kunopfuudzwa kuburikidza ne relief valve kudzokera kutangi, zvichibvisa simba sekupisa. Munguva yekutonhodza - apo pasina hydraulic flow inodiwa zvachose kunze kwe clamp tonnage diki - pombi ichiri kutenderera nekumhanya kwakazara, ichiri kutora simba rakazara, uye bypass valve ichiri kurasa kuwanda kwemvura. Uku ndiko kusashanda zvakanaka kwechimiro che fixed-pomp system: mota ne pombi zvinomhanya panzvimbo imwe chete, uye chero kusawirirana pakati penzvimbo iyoyo ne hydraulic demand chaiyo kunorasika sekupisa.

Kupisa pachakwo hakuna mahara. Oiri yehydraulic inofanira kutonhodzwa kuti irambe yakasvibira uye kudzivirira oxidation, zvinoreva kuti imwe oiri inotonhodza (inotonhodzwa nemvura kana inotonhodzwa nemhepo) iri kushanda nguva dzose, ichiwana simba rakawedzerwa. Kudiwa kwekutonhodza pamuchina wemagetsi we250-ton mu30 °C kwakakura - kazhinji kuri pakati pe15–25% yemagetsi emuchina pakushanda kwekuchinjana katatu.

Mashandisiro anoita Servo-Hydraulic System Simba

Sisitimu yeservo-hydraulic inotsiva mota inomhanyisa nguva dzose nemota yeservo inoshanduka-shanduka — kazhinji mota inoshanduka-shanduka yemagineti (PMSM) — inofambiswa nemota inoshanduka-shanduka (VFD). Servo drive inodzora kumhanya kwemota kuti ienderane nezvinodiwa nehydraulic panguva chaiyo. Kana cycle iri muchikamu chekuyerera kwepamusoro (kuvharwa kwemould, kuisirwa injection, kuisirwa plastici), mota inokwira nekumhanya kwakanyanya. Kana cycle iri muchikamu chekuyerera zvishoma (kubata, kutonhora), mota inokwira nekumhanya kwakaderera iyo inongosangana nezvinodiwa nehydraulic chaiyo. Kana cycle iri pakuzorora (pasina kufamba), mota inogona kumira zvachose kana kumhanya nekumhanya kwepedyo nezero.

Mugumisiro wacho ndewekuti muchina we servo-hydraulic unongotora simba raunoda pachikamu chimwe nechimwe chedenderedzwa. Mota haifambi nekumhanya kwakafanana, pombi haipfuure kuyerera kwakawandisa, uye kupwanyika kwekupisa kwe bypass-valve kunotsanangura kusashanda zvakanaka kwekudhinda kunobviswa zvakanyanya.Bosch Rexroth, Yuken, nevamwe vagadziri vema hydraulic system vanoburitsa manotsi ekushandisa nekuenzanisa kushandiswa kwesimba reservo ne rakagadzirwa; huwandu hwakajairika mu data rakabudiswa ikuderedza simba ne40–80% pazvikamu zvine zvikamu zvakakosha zvekubata nekutonhodza, uye kudzikira ne20–40% pazvikamu zvine zvikamu zvipfupi zvekubata nekutonhodza.

Mari inochengetwa haina kufanana muchikamu chose. Mari yakawanda inochengetwa iri muchikamu chekutonhodza (chikamu chakareba kwazvo chisingadewi zvakanyanya muzvikamu zvakawanda), chechipiri pakukura muchikamu chekubatirira, uye chidiki pachikamu chekubatirira (apo kuyerera kwepamusoro kunodiwa uye sisitimu yeservo iri kushandawo pakukwirira). Pachishandiso chemazuva ano che250-ton chinoumba chikamu che200 g ABS chine 25-second cycle, chikamu chekutonhodza chinenge 50% yechikamu, chikamu chekubatirira 15%, chikamu chekupinza nepurasitiki 25%, uye chikamu chekuvhura/kuvhara 10%. Chikamu chekutonhodza ndipo panochengetedzwa zvakanyanya nemuchina weservo.

Iyo Servo Premium: Mutengo weCapital vs Mutengo weKushanda
