Mu ma hydraulic systems,mapampu a pistonamagwiritsidwa ntchito kwambiri chifukwa chapamwamba kwambiri, kuthamanga kwambiri komanso kudalirika kwambiri. Koma monga zida zonse zamakina, mapampu a pistoni ali ndi zovuta zawo.
Ngakhale kuti nthawi zambiri amagwiritsidwa ntchito pazochitika zofunidwa kwambiri monga kupanga mafakitale ndi makina omanga, zovuta zake zazikulu ndi: mtengo wapamwamba ndi dongosolo lovuta. Sikuti mtengo wogula ndiwokwera, koma kukonza kotsatira kumakhala kovuta komanso kokwera mtengo.
Poocca Hydraulic Manufacturer imayambitsa momwe mapampu a piston amagwirira ntchito, ubwino wake, ndi kuipa kwake kwakukulu. Kaya mukukonzekera kusankha pampu ya hydraulic ya chipangizo chatsopano kapena mukufuna kukweza makina omwe alipo, kumvetsetsa ubwino ndi kuipa kumeneku kungapangitse chisankho choyenera chogula.
Kodi pampu ya pistoni ndi chiyani?
Pampu ya pistoni ndi mpope wabwino wosuntha womwe umakakamiza ndikupereka mafuta a hydraulic kudzera mukuchitanso kwa pistoni imodzi kapena zingapo. Mapampu amatha kuthamanga kwambiri - nthawi zambiri mpaka 350 bar kapena kuposerapo - choncho ndi oyenerera ku ntchito zolemetsa monga zipangizo zomangira, makina osindikizira ndi ma hydraulics oyendetsa sitima.
Pali mitundu iwiri yonse:
Mapampu a axial piston (mwachitsanzo, mapangidwe a swashplate)
Mapampu a piston a Radial
Aliyense ali ndi ubwino wake potengera kukakamiza, kuyenda ndi kuwongolera njira.
Ubwino waukulu wa mapampu a pistoni
Tisanafotokoze zovuta zazikulu zamapampu a pistoni, ndikofunikira kudziwa zifukwa zomwe anthu amakonda kusankha mapampu a pistoni m'malo mwa zida kapena mapampu a vane:
Kupanikizika kwakukulu: Nthawi zambiri amavotera 280-400 bar mosalekeza.
Kuchita bwino kwambiri: Kuchita bwino kwa volumetric nthawi zambiri kumapitilira 90%, ngakhale atanyamula katundu.
Mphamvu yophatikizika: Yaing'ono komanso yamphamvu kuposa mapampu amagetsi.
Zosintha zosunthika: Zoyenera kugwiritsa ntchito zomverera zomwe sizingawononge mphamvu.
Kuwongolera kolondola: Koyenera kugwiritsa ntchito zotsekeka komanso zowongolera za servo.
Ndi zabwino izi, mapampu a pistoni amakonda kukhala "mapeto apamwamba" pakupanga ma hydraulic.
Zoyipa zazikulu: mtengo ndi zovuta
Ndipo tsopano kubwerera ku funso lofunika: Kodi chachikulu kuipa kwake ndi chiyanimapampu a pistoni a hydraulicm'ma hydraulic systems?
Yankho lake ndizovuta kwambiri komanso zovuta zamakina, kutanthauza kukonza kwapamwamba komanso mtengo wa umwini pakapita nthawi.
a. Mtengo woyamba
Mapampu a piston ndi okwera mtengo kwambiri kuposa ma giya kapena mapampu amtundu womwewo. Izi ndichifukwa cha:
Makina olondola a pistoni, masilindala ndi mbale za swash
Njira zowongolera zovuta (monga zowongolera ndi kuthamanga)
Kugwiritsa ntchito ma alloys amphamvu kwambiri komanso makina apadera osindikizira
Mwachitsanzo, pampu ya pisitoni ya Rexroth A10VSO imatha kuwononga nthawi 3-5 kuposa pampu yamagetsi yofananira.
b. Kukonza zovuta
Mosiyana ndi mapampu amagetsi, mapampu a pistoni amaphatikiza magawo ambiri osuntha: ma pistoni ndi nsapato, ma valve, mbale zotsuka, zonyamula ndi zosindikizira.
Chifukwa chake, malo ovala ndi olephera amachulukidwa, ndipo kukonza nthawi zambiri kumafuna kupasuka ndi anthu ophunzitsidwa bwino m'chipinda chaukhondo. Kugwira ntchito molakwika kungayambitse: kutayikira kwamkati, kugoletsa mbale, kugwidwa kwa piston, kutenthedwa kapena cavitation.
c. Kumva kuipitsidwa
Choyipa china ndi kulekerera kutsika kochepa. Mapampu a pistoni ali ndi zilolezo zazing'ono kwambiri zamkati - nthawi zambiri mumitundu ya micrometer. Ngakhale dothi laling'ono, madzi kapena zitsulo zometa zingayambitse: kuwonongeka kwa mbale ya valve, kuvala msanga kwa nsapato za pistoni, ndi kuchepetsa kupanikizika kwa dongosolo, zomwe zikutanthauza kuti makina apamwamba a kusefedwa amafunikira, zomwe zimawonjezera mtengo wa dongosolo lonse.
d. Phokoso ndi kunjenjemera
Osati kuipa koipitsitsa, koma mapampu ena a pistoni amamveka mokweza komanso amanjenjemera kuposa mapampu amtundu wina, makamaka akalemedwa mosiyanasiyana kapena m'malo ovuta kuyikika.
Ndi liti pamene osagwiritsa ntchito pampu ya pistoni?
Kudziwa nthawi yoti musagwiritse ntchito pampu ya pistoni kudzakutetezani kuti musapangidwe mopambanitsa komanso kuwononga ndalama zambiri.
Chitsanzo Ganizirani njira zina
Makina otsika (<150 bar) Mapampu amagetsi kapena vane
Ntchito zotengera mtengo Pampu zamagetsi (zachuma, zolimba)
Makina oipitsidwa kapena otsika kwambiri amadzimadzi Mapampu a gear (osakhudzidwa kwambiri ndi kuipitsidwa)
Zozungulira zozimitsa zokhala ndi mapampu osavuta osunthika osasunthika
Zida zazing'ono zam'manja za Micro gear kapena mapampu a vane
Pazifukwa izi, chiŵerengero chamtengo wapatali cha pampu ya pistoni sichiri chabwino.
Njira Zina za Piston Pampu
Nachi chifaniziro chachidule:
Mapampu a Hydraulic Gear:
✅ Zotsika mtengo
✅ Chokhalitsa komanso chosamva madzi akuda
❌ Kuchepetsa mphamvu komanso kupanikizika
Mapampu a Hydraulic Vane:
✅ Yabata pang'ono kuposa mapampu amagetsi

Momwe mungasankhire: pampu ya piston kapena ayi?
Musanasankhe pampu ya pistoni, ganizirani mafunso awa:
Ndi zipsinjo zotani zofunika ndi kuyenda?
Kodi kuchita zinthu mwanzeru n'kofunika bwanji?
Ndi zokonza zotani zomwe zilipo?
Kodi pali zovuta zilizonse zoyipitsidwa?
Kodi bajeti yozungulira moyo ndi yotani?
At Poocca Hydraulic Manufacturers, timapereka chithandizo chaumisiri chaulere kuti tithandize makasitomala kusankha njira yotsika mtengo kwambiri ya dongosolo lawo - kaya ndi pampu ya pistoni, pampu ya gear kapena kasinthidwe ka hybrid.
Zoyipa zazikulu zamapampu a pistoni ndizokwera mtengo komanso kukhudzika kwawo, potengera mtengo wogula komanso zofunikira pakugwirira ntchito. Ngakhale kuti sizingafanane ndi ntchito yogwira ntchito komanso yokakamiza, ubwino umenewu umabweranso ndi malonda a zovuta ndi kukonza ndalama.
Pomvetsetsa ubwino ndi malire a mapampu a pistoni, opanga makina ndi magulu ogula zinthu amatha kupanga zisankho zambiri, zotsika mtengo.
Mafunso Ofunsidwa Kawirikawiri (FAQ)
1. Chifukwa chiyani mapampu a pistoni ndi okwera mtengo kuposa mitundu ina ya mapampu a hydraulic?
Mapampu a pistoni amafunikira zida zolondola kwambiri monga ma pistoni, ma valve, ndi mbale za swash. Amapangidwa ndi njira zovuta kwambiri komanso kulolerana kolimba kuposa ma gear kapena mapampu a vane. Izi zimabweretsa ndalama zopangira zokwera, zomwe zimawonekeranso pamitengo yamisika.
2. Kodi mapampu a pistoni amafunikira chisamaliro chapadera?
Inde. Chifukwa cha kapangidwe kake kovutirapo komanso kukhudzidwa kwa kuipitsidwa, mapampu a pistoni nthawi zambiri amafunikira kuwunika pafupipafupi kusefera kwamafuta, kuwunika kwanthawi zonse, komanso kusokoneza ndikukonzanso m'zipinda zoyera. Kusakonzekera kungayambitse kulephera msanga.
3. Kodi chimachitika ndi chiyani ngati pampu ya pistoni ikuyendetsedwa ndi madzi oipitsidwa kapena akuda?
Mapampu a pistoni ali ndi zolowera zolimba kwambiri zamkati motero amatha kuipitsidwa ndi madzimadzi amadzimadzi ndi dothi, madzi, kapena tchipisi tachitsulo. Kuipitsidwa kumatha kuwononga mbale za valve, silinda ndi nsapato za pistoni, ndipo kungayambitse kutulutsa kwamkati, kutaya mphamvu, kapena kulephera kwathunthu.
4. Kodi ndi bwino kugwiritsa ntchito mpope wa plunger mu ntchito yotsika kwambiri?
Osati kawirikawiri. M'makina ocheperako a bar 150 kapena kuchepera, mapampu a vane kapena mapampu amagetsi nthawi zambiri amakhala otsika mtengo komanso osakonza zambiri. Kuthamanga kwambiri, kuwongolera molondola kapena kusuntha kosinthika ndikoyenera kwambiri pamapampu a pistoni.
5. Kodi mpope wa plunger udzatha nthawi yayitali bwanji?
Pokonzekera bwino komanso madzi atsopano a hydraulic, mpope wabwino kwambiri wa plunger (monga Rexroth, Parker kapena Poocca) ukhoza kukhala maola 5,000 mpaka 10,000 kapena kupitirira. Mosiyana ndi izi, kukonza koyipa kapena kuipitsidwa kwamadzimadzi a hydraulic kudzafupikitsa moyo wake wautumiki.
6. Kodi Poocca Hydraulics idzandithandiza kusankha pampu yoyenera ya dongosolo langa?
Pamenepo. Opanga a Poocca Hydraulics amaphatikiza upangiri waulere waukadaulo komanso chitsogozo chogwiritsa ntchito. Kaya pampu ya plunger, pampu ya giya kapena pampu ya vane, timatha kukutsogolerani kuti muzitha kuyendetsa bwino ntchito ndi mtengo wake kuti muzitha kugwira bwino ntchito ndikuchepetsa mtengo wake pakapita nthawi.
Lumikizanani ndi Pooccakwa njira yoyenera yapampu
Ngati simukutsimikiza ngati pampu ya pisitoni ingakhale yoyenera kugwiritsa ntchito ma hydraulic, foni Poocca Hydraulic Manufacturers. Tili ndi mapampu ambiri a plunger, mapampu amagetsi, mapampu a vane ndi ma hydraulic motors, kuphatikiza Rexroth A10VSO, Parker PVP, Kawasaki K3V ndi mapampu athu osiyanasiyana a Poocca, kuti muwonetsetse kuti mukulandira mpope wolondola pamtengo wolondola komanso ndi chithandizo chonse chaukadaulo.
