Musiyano uripo pakati pekuyera vharafu uye maviri-nzira hydraulic lock
2024-02-06Overview
Bi-directional hydraulic locks uye balancing mavharuvhu anogona kushandiswa seanokiya zvikamu mune mamwe mamiriro kuti ave nechokwadi chekuti chishandiso chinoshanda hachizotsvedza, kumhanyisa kana kufamba nekuda kwezvikonzero zvekunze sehuremu hwayo.
Zvisinei, pasi pemamwe mamiriro ekumhanya-mhanya, haagoni kushandiswa zvakasiyana. Ngatitaurei nezve mamwe maonero emunyori pamusoro pemagadzirirwo mafomu ezvigadzirwa zviviri.
Nzira mbiri dze hydraulic lock ndiyo Nhamba ye2 chikamu chiri kurudyi rwemavhavha maviri emagetsi anoshandiswa pamwe chete (ona Mufananidzo 1). Inowanzo shandiswa mukutakura-inotakura hydraulic cylinders kana mota yemafuta maseketi kudzivirira iyo hydraulic cylinder kana mota kubva pakutsvedza pasi pasi pekuita kwezvinhu zvinorema. Kana chiito chinenge chichidiwa, mafuta anofanira kupiwa kune imwe dunhu, uye imwe-nzira valve inofanira kuvhurwa kuburikidza nemukati wekutonga mafuta wedunhu kubvumira dunhu remafuta kuti Chete kana rakabatana rinogona kushanda hydraulic cylinder kana motokari.
Pamusana pekugadzirwa kwemagetsi pachayo, panguva yekufamba kwe hydraulic cylinder, uremu hwakafa hwemutoro hunowanzokonzera kurasikirwa kwepakarepo kwekumanikidzwa muimba huru yekushanda, zvichiita kuti vacuum. Izvi zvinowanzoitika pamichina inotevera yakajairika:
Silinda yakaiswa vertically mune ina-column hydraulic press;
Upper mold cylinder yezvidhinha kugadzira michina;
Silinda yemafuta inotenderera ichienda mberi neshure mumichina yegirazi;
Swing cylinder yemichina yekuvaka;
winch motor ye hydraulic crane;
Iyo inonyanya kushandiswa hydraulic lock ndiyo yakaturikidzana cheki vharafu. Ngatitarisei pachikamu chayo chemuchinjiko uye chakajairwa application.
Kana huremu huchidonha nehuremu hwayo, kana rutivi rweoiri rwekudzora rusina kuzadzikiswa nenguva, vacuum inogadzirwa padivi reB, zvichiita kuti piston yekudzora idzoke pasi pechiito chechirimo, icho chinovhara nzira imwe chete. vharafu, uye zvino ramba uchipa mafuta, uchiita kamuri yekushanda Kumanikidza kunokwira uye kunovhura iyo-imwe nzira valve. Kugara kwakadaro kuvhura uye kuvhara zviito zvinokonzeresa kuti mutoro uenderere mberi nguva nenguva panguva yekudonha, zvichikonzera kukanganisa kukuru uye kudedera. Naizvozvo, maviri-nzira hydraulic locks kazhinji haakurudzirwe kune yakakwirira-kumhanya uye inorema-mutoro mamiriro, asi inowanzoshandiswa. Inokodzera zvishwe zvakavharwa zvine nguva yakareba yekutsigira uye yakaderera kufamba nekukurumidza.
Mukuwedzera, kana iwe uchida kugadzirisa dambudziko iri, unogona kuwedzera throttle valve padivi rekudzoka kwemafuta kuti udzore kukurumidza kudonha kuitira kuti kuyerera kwepombi yemafuta kukwane zvakakwana kudiwa kwemafuta ekudzora.
Zvimiro zvekuenzanisa valve:
Counterbalance valve, inonziwo speed limit lock (ona Figure 3), ivharuvhu inodzorwa nekunze uye inobuda mukati meimwe nzira yekutevedzana kwevharuvhu. Inoumbwa nevhavha yenzira imwe uye vheji yekutevedzana inoshandiswa pamwechete. Mune hydraulic circuit, inogona kuvhara iyo hydraulic cylinder kana mota. Oiri muoiri redunhu inokonzera iyo hydraulic cylinder kuti
1-kuguma chivharo; 2, 6, 7-chitubu chigaro; 3, 4, 8, 21-chirimo;
5, 9, 13, 16, 17, 20 - kuvhara mhete 10 - poppet valve; 11 - vharafu core;
- 14-vharafu sleeve; 15-kudzora piston; 18-control port cover cover 19-musoro;
22-One-way valve core; 23-Valve muviri
Mufananidzo 3 Chimiro dhayagiramu yevhavha yekuenzanisa
Kana kuti mota haizotsvedza pasi nekuda kwehuremu hwemutoro, uye ichaita sekiyi panguva ino. Kana iyo hydraulic cylinder kana mota inoda kufamba, fluid inopfuudzwa kune imwe dunhu reoiri, uye panguva imwe chete, iyo yemukati mafuta wedunhu reyevhavhavhavha inotonga kuvhurwa kwevhavha yekuteedzera kubatanidza dunhu uye kuona mafambiro ayo. Sezvo magadzirirwo evhavhavha yekutevedzana pachayo akasiyana neaya maviri-nzira hydraulic lock, imwe yekumashure kudzvanywa kunowanzo kusimbiswa munharaunda yekushanda kana ichishanda, kuitira kuti basa guru reiyo hydraulic cylinder kana mota isaite kumanikidza kwakashata. nekuda kwehuremu hwayo uye nekumhanyisa kutsvedza, saka hapana kufamba kwemberi kuchaitika. Kukatyamadzwa uye kudedera kunge mbiri-nzira hydraulic lock.
Naizvozvo, mavharuvhu ekuyeresa anowanzo shandiswa mumaseketi ane kumhanya kwakakwira uye mutoro unorema uye zvimwe zvinodikanwa zvekukurumidza kugadzikana.
Mufananidzo 3 ivharuvhu inopikisa ine chimiro cheplate, uye pazasi pane-cross-sectional maonero e-plug-in counterbalance valve.
Mhedziso
Kubatanidza kuongororwa kwemaitiro evhavhavhavha uye maviri-nzira hydraulic lock, munyori anokurudzira:
Panyaya yekuderera kwekukurumidza uye mutoro wechiedza nezvinodiwa zvakaderera pane kugadzikana kwekumhanya, kuitira kuderedza mari, nzira mbiri ye hydraulic lock inogona kushandiswa sevhavha yedunhu. Nekudaro, muzviitiko zvekumhanya zvakanyanya uye mutoro unorema, kunyanya painoda kugadzikana kwakanyanya kunodiwa, maviri-nzira hydraulic lock inofanira kushandiswa. Paunenge uchishandisa chiyero chevharuvhu sechikamu chekuvhara, haufanirwe kuteedzera kudzikisa mutengo uye sarudza nzira mbiri hydraulic lock, zvikasadaro zvinokonzeresa kurasikirwa kukuru.
