Sei pedal imwe chete ye hydraulic control foot inoshandiswa zvakanyanya mumichina yekuvaka?

Muma hydraulic control systems emuchina wekuvaka akadai sema loaders, ma cranes, uye ma excavators, pedal imwe chete ye hydraulic control foot yakajairika. "Unyanzvi" hupi hwainovimba nahwo kuti ive "muenzi wechigarire" mu hydraulic system yemuchina wakadaro? Izvi zvinokonzerwa nekuti hunhu hwayo hwakanyatsogadziriswa kuti huenderane nekushanda kwemichina yekuvaka.

Chinhu chikuru chepedal imwe chete ye hydraulic control foot ivharuvhu yetsoka yemakanika, uye pfungwa yekushanda kwayo haina kuoma: nekutsika kana kusunungura pedal yetsoka, kuvhurwa nekuvharwa kwevharuvhu yemukati kunodzorwa, nokudaro zvichiita kuti kuyerera kwe hydraulic system kuchekwe uye kuchinja kwenzira yekuyerera kwayo. Nzira yekushanda inoita seiri nyore inogona kuita basa rakasiyana munzvimbo yekushanda kwemichina yekuvaka.

1. Kurongeka kwekushanda: sunungura maoko ako uye tarisa pamabasa makuru

Kushanda kwemichina yekuvaka kunowanzoda kurongeka kwezviito zvakawanda. Tichitora semuenzaniso wemuchina wekuchera, mushandi anofanira kudzora kuchera nekuburitsa bhaketi, uye kugadzirisa mamiriro eboom neruoko rwekudhibha. Maoko ese ari maviri ane mutoro wakakura wekushanda zvakanaka. Kubuda kwepedal imwe chete yehydraulic control foot kunoita kuti "tsoka" ive fulcrum itsva yekudzora system yehydraulic - nekutsika pedal, kuyerera kana gwara re hydraulic circuit rinogona kugadziriswa pasina kumisa kushanda kweruoko. Semuenzaniso, kana muchina wekuchera uchienzanisa nzvimbo, pedal yetsoka inodzorwa netsoka inogadzirisa kumanikidzwa kwe hydraulic ye boom, uye maoko ese ari maviri anotarisa pakuenzana kwebhaketi zvishoma. Maitiro ekushanda anonyatsoenderana uye kushanda zvakanaka kwekushanda kunovandudzwa zvechisikigo.

Munguva yekuburitsa zvinhu mu loader, mutyairi anofanira kudzora kona yekutsvedza kwebhaketi uye kutyaira kwemotokari panguva imwe chete. Chitsigiro chetsoka che hydraulic chimwe chete chinobvumira tsoka kutora basa rekudzora kumanikidzwa kwe hydraulic mubhaketi, uye maoko ese anogona kushandisa chidhiraivho nekuchinjika uye kudzora kumhanya kwemotokari, zvichiita kuti nzvimbo yekuburitsa zvinhu ive yakarurama, kudzivirira kurasikira kwezvinhu, uye kuvandudza mamiriro ekuvaka. Iyi nzira ye "kupatsanurwa kwebasa nemaoko" inosangana nezvinodiwa zve multi-action coordinate operation yemichina yeinjiniya, inovandudza zvikuru ruzivo rwekushanda, uye inoderedza kuneta kwemushandi.

2. Kugadziriswa kwekushanda: kuchinjika uye kwakarurama, kubata nemamiriro ezvinhu akaomarara ekushanda

(I) Kushanda kwemativi maviri uye kugadzirisa zvishoma

Mamiriro ekushanda anotarisana nemichina yeinjiniya akaoma uye akasiyana-siyana, uye kuchinjika uye kururama kwekudzora kwe hydraulic kwakanyanya kwazvo. Mavharuvhu mazhinji etsoka dze hydraulic anotsigira mashandiro emativi maviri. Kuwedzera kune mabasa ekutanga ekuvhura vharuvhu nekutsika pairi uye kuivhara nekuisunungura, mamwe magadzirirwo anogonawo kugadzirisa pedal stroke uye simba re pedal.

Tichitora mashandiro ekusimudza crane semuenzaniso, kusimudza zvinhu zvine huremu hwakasiyana kunoda mwero wakasiyana wekuyerera kwe hydraulic. Nekugadzirisa pedal stroke, kuvhurika kwevharuvhu kunogona kudzorwa kuti pave nekuchinja kudiki muhuwandu hwekuyerera kwemafuta e hydraulic, zvichiita kuti boom lift nekudonha zvive zvakagadzikana uye kudzivirira zvinhu zvinorema kuti zvisazununguke. Munguva yekushanda kwekupwanya excavator, simba repedal rinogadziriswa zvichienderana nekuoma kwedombo kudzora frequency nesimba rehammer kuti ienderane nehukuru hwakasiyana hwekuvaka uye kuvandudza mashandiro. Kugona uku kwekugadzirisa kunochinjika kunobvumira pedal imwe chete ye hydraulic control foot kuti "ienderane nemamiriro emuno" uye ienderane nemamiriro akasiyana ekushanda.

(II) Muperekedzi akavimbika uye anogara kwenguva refu, akasimba

Nzvimbo yekushanda kwemichina yekuvaka yakaoma, uye sisitimu ye hydraulic inomanikidzwa zvakanyanya uye inodedera kwenguva yakareba, izvo zvinoisa zvinodiwa zvakanyanya pakuvimbika kwezvikamu. Pedal imwe chete ye hydraulic control foot yakagadzirwa nezvinhu zvisingapfeki uye zvinopesana nekumanikidzwa zvakanyanya. Muviri wevharuvhu uye chimiro chekuvhara zvakagadziridzwa uye zvinogona kushanda zvakadzikama munzvimbo ine hydraulic ine pressure yakawanda, zvichidzivirira matambudziko ekubuda kwemvura.

MaLoader anoshanda mumigodhi anosangana neguruva, mabumps, uye hydraulic shocks ine simba guru. Chinhu chinodzivirira kupera chepedal chinogona kuramba kupera kwenguva refu, uye kuramba kwekumanikidzwa kwakanyanya kunoita kuti vharuvhu irambe ichivharika zvakanaka kana kumanikidzwa kwesystem kuchichinja-chinja. Kunyangwe nekushandiswa kwenguva refu kwenguva refu, mashandiro ayo anoora zvishoma nezvishoma, zvichideredza nguva yekushanda kwemidziyo inokonzerwa nekukundikana kwezvikamu, zvichiita kuti kuvaka kurambe kuripo, uye "kufukidza" kufambira mberi kweprojekiti.

3. Mamiriro ezvinhu akaomarara: kuzadza mukaha wekushanda kwekutonga kwe hydraulic

Sisitimu yehydraulic yemichina yekuvaka inoda nzira iri nyore, inoshanda uye yakaoma yekudzora mashandiro. Mavharuvhu emaoko anoda zviwanikwa zvekushandisa nemaoko uye anogona "kubatikana zvakanyanya" nyore nyore mumamiriro ezvinhu ekubatanidza mabasa akawanda; kunyangwe vharuvhu yekudzora yemagetsi yakarurama, inogumira pamutengo, waya uye kugona kuchinjika kwezvakatipoteredza (senge nzvimbo dzine hunyoro neguruva dzinogona kutadza kushanda).

Chidzitiro chimwe chete che hydraulic control pedal chinodzivisa zvimwe zvikanganiso zvemavharuvhu emaoko nemavharuvhu emagetsi emagetsi nenzira ye "mechanical structure + foot operation": hapana waya dzakaoma dzinodiwa, hapana kutya kukanganiswa nemamiriro ezvinhu akaoma, uye misimboti yemakanika iri nyore uye yakavimbika inoshandiswa kuzadzisa mashandiro e "diversion" e hydraulic control. Inozadzisa chinodiwa che "operation fulcrums kunze kwemaoko" mukudzora hydraulic yemichina yekuvaka, zvichiita kuti maitiro ekushanda ave akakodzera uye anoshanda, uye zvinova sarudzo "yakajairwa" yema hydraulic systems e loaders, cranes, excavators nezvimwe zvishandiso.

Kubva pakuvandudza kushanda zvakanaka kwekushanda, kusvika pakururamisa uye kugara kwenguva refu kwekugadzirisa mashandiro, kusvika pakuzadza mukaha wezvinodiwa zvakanyanya munzvimbo, pedal imwe chete ye hydraulic control foot inosangana zvakadzama nezvinodiwa zvekushanda kwemichina yekuvaka ine hunhu hwayo. Kunyangwe iri diki, inoita basa guru mu "control link" ye hydraulic system, ichibatsira michina yekuvaka kushanda zvakadzikama uye zvinobudirira mumamiriro ekushanda akaomarara, ichiva "gamba rekuseri kwezviitiko" kukurudzira kukura kwakanaka kwekuvaka kweinjiniya, uye zvakare kududzira pfungwa dziripo dzezvikamu zvemaindasitiri zviri kushandiswa zvakanyanya nekuda kwe "kugadziriswa kwakakodzera kwezviitiko".
