Umsabalalisi unemigqa emithathu yokusebenza yokuhlinzeka ngoketshezi olusebenzayo, olutholakala ngokuhambisana nesikhathi sokushintsha indawo yama-spools; umugqa wokukhipha "B" - uxhuma imigodi yama-valve e-bypass kanye nama-spools, umugqa wokukhipha "C" - uxhuma ukuvuleka kwama-spools, umugqa wokulawula we-valve ye-bypass "G" udlula endlini yokusabalalisa kanye nezimbobo kuma-spools, Ipayipi ixhunywe ku-valve ye-bypass 14 I-piston ye-valve ye-bypass ifakwe i-throttle jet 13 ukuze idale ukwehla kokucindezela esiteshini sokukhipha kanye nezimbobo ngaphansi kwepiston, okuqinisekisa ukuvulwa kwayo endaweni engathathi hlangothi.

Amakhoyili avimba futhi avule imigqa yokusebenza enezikhala zokuphonseka. Ukuphatha kwenziwa kusetshenziswa ama-levers, atholakala kukhava engezansi ye-distributor. Ama-levers axhunywe kuma-spools ngokusebenzisa i-spherical hinge 9 ene-plastic inserts 10 kanye nendandatho yokuvala 8. Kusukela ngaphandle, i-hinge ivaliwe nge-rubber bushing 6. Ama-spools amathathu akuvumela ukuba ulawule ngesikhathi esisodwa ukusebenza kwama-actuator amathathu we-hydraulic.

Ukuthi isebenza kanjani

Isigubhu ngasinye, kuye ngendawo esethiwe, sisebenza ngezindlela ezine:

• "Ukungathathi hlangothi": Indawo emaphakathi phakathi kwendawo "phezulu" nendawo engezansi "phansi". I-valve ye-bypass ivulekile futhi ikhiphela uketshezi olusebenzayo ku-drain. Ama-spools avimba zonke iziteshi, elungisa indawo ebekwe ngaphambili yama-actuator we-hydraulic.
• "Rise": isikhundla sokuqala esiphezulu ngemva "ukungathathi hlangothi". I-valve yokudlula ivala imbobo yokukhipha amanzi. I-spool idlulisela uwoyela ukusuka kumzila wokulahla kuya kulayini wokuphakamisa isilinda.
• "Ukwehla okuphoqelelwe" - indawo ephansi kakhulu ngaphambi kokuphela "okuntantayo". I-valve yokudlula ivala imbobo yokukhipha amanzi. I-spool idlulisa uwoyela ukusuka esiteshini sokukhipha kuya kulayini wokubuya we-hydraulic cylinder.
• "Ukuntanta" - indawo ephansi kakhulu ye-lever. Ivalvu ye-bypass ivulekile futhi ikhipha uketshezi olusebenzayo lusuka empompini luye ku-drain. Kule ndawo, uketshezi olusebenzayo lugeleza ngokukhululekile nhlangothi zombili lusuka kuyo yomibili imigodi yesilinda esidonsa amanzi. I-hydraulic cylinder isendaweni yamahhala futhi isabela esenzweni sezimo zangaphandle kanye namandla adonsela phansi omshini. Ngakho-ke, kuvumela izindikimba ezisebenzayo zomshini ukuthi zilandele indawo ngesikhathi sokulima futhi zigcine ukujula kokulima okuzinzile.

Ukusebenza kwe-Spool retainer

Ama-spools afakwe i-valve yasentwasahlobo engu-3 ukuze abuyele ngokuzenzekelayo endaweni engathathi hlangothi kanye nezithinti zebhola eziwabamba endaweni ekhethiwe. I-automatic reverse ball valve iyasebenza lapho ingcindezi ohlelweni idlula i-12,5-13,5 MPa. Ukucindezela okwedlulele kwenzeka lapho isilinda se-hydraulic sifinyelela endaweni yokugcina endaweni ehambisanayo yokuphakamisa nokwehlisa okuphoqelelwe, kanye nalapho uhlelo lugcwele ngokweqile.

I-hydraulic distributor ifakwe idivayisi yokusiza ingcindezi yesimo esiphuthumayo 20. I-valve yokuphepha ilungiswa ukuze ikhulule ukucindezela ngaphezu kwe-14,5 kuya ku-16 MPa. Ukulungiswa kwenziwa nge-screw 18, eshintsha izinga lokucindezelwa kwentwasahlobo ye-valve yebhola 17. Idivayisi ibangelwa lapho umshini wehluleka - i-spool yomshini kanye nedivayisi ye-bypass ihluleka.

Ukungasebenzi okujwayelekile komsabalalisi we-MTZ

Okunamathiselwe akuphakamisi

Lokhu kungase kube ngenxa yemfucumfucu engena ohlelweni lwe-hydraulic ngaphansi kwevalve yokudlula. Kulokhu, i-valve ye-bypass ayivali - uketshezi olusebenzayo lungena emgodini wokudonsa. Umthengisi akaphenduli ekushintsheni ukuma kwama-reels. Kukhishiwe: khumula amabhawodi amabili esembozweni sevalve yokudlula, susa isiphethu ngevalvu bese ususa udoti.

Esimweni sokungabikho noma ukwehla komthamo womthwalo we-hydraulics kagandaganda, okuhambisana nokushiswa ngokweqile kwamafutha ohlelweni, ukuvela komsindo ozwakalayo endaweni ye-lever "lift" kukhombisa ukwehla kwezinga likawoyela nokuvuza komoya ngaphakathi. uhlelo.

Okunamathiselwe akukhiyi endaweni ephakanyisiwe

Isizathu ukucindezelwa kwe-high-pressure hydraulic hoses kanye nama-hydraulic couplings, ukugqokwa kwe-compress seal ye-piston noma induku yesilinda samandla we-hydraulic, ukugqokwa kwama-spools akhuphukayo, ukubukeka kwamagobolondo ku-valve ye-bypass evimbela i-valve. ekuvaleni kuqinise.

Ayehlisi, ayiphakamisi okunamathiselwe kwi-imeyili

Isizathu siwukuthi ukuvinjelwa kwemigqa yokusebenza yabasabalalisi kuvimbela ukudlula kwamafutha. Ukulungiswa kokugeleza kukawoyela akunakwenzeka. Qeda: qaqa futhi ushaye, futhi uhlanze imigqa, futhi uhlole ukusebenza kwama-valve.

Okunamathiselwe kwehla kakhulu

Lokhu kubonisa ukwehla okukhulu kwengcindezi ohlelweni; uma kwenzeka ikhefu emigqeni kawoyela kanye nokwehla kwezinga loketshezi olusebenzayo, ukungena komoya okuqinile kwesistimu. Qeda: buyisela amapayipi awonakele, hlola ukuqina kokuxhumeka kwesistimu, engeza amafutha ezingeni elidingekayo.

I-automatic neutralization ayisebenzi lapho isilinda esisebenza nge-hydraulic siphakanyiswa noma sehliswa ngokugcwele

Isizathu ukungasebenzi kahle kwe-valve yebhola "i-spool position lock self-closing". Susa; qaqa, buyisela izingxenye ze-valve ezigugile kanye nezimpawu.

ukuhlola

Umsabalalisi uyahlolwa ngemva kokuhlola ukusebenza kwephampu ye-sheh hydraulic yesistimu ngesivinini senjini elinganiselwe, ebeka inani loketshezi olusebenzayo olukhishwe ngamalitha ngomzuzu wokusebenza.

Ukuxhumana kwe-hydrodistributor

Ku-MTZ 82 (80), ibhulokhi itholakala odongeni olungaphambili ngaphakathi kwekhabhini ngaphansi kwedeshibhodi. Ama-levers okulawula axhunywe kuma-spools ngokusebenzisa i-axis, futhi izinduku zichazwe ngakwesokudla kwephaneli. Idizayini ye-distributor ivumela, lapho uhambisa iyunithi kwenye indawo noma uyifake kwamanye amamodeli kagandaganda, ukushintsha indawo yezintambo ngokufaka kabusha ikhava enezindawo zokubeka izinsimbi ngakolunye uhlangothi lwezindlu zokusabalalisa. Ukuze uxhumeke kalula kuma-hydraulic kanye nezinto zokusebenza ezisebenza ngamanzi, izingxenye zokugcina zeyunithi zinezindawo zokuphuma ezingasasebenzi ngaphambili neseceleni zokuphakamisa nokwehlisa. Ngaphezu kwalokho, ukuxhumana ngesikhathi esisodwa ezindaweni ezimbili ze-spool kuvumela ukulawula kanyekanye kwamasilinda amabili we-hydraulic.

Izimbobo ezinentambo, ezimakwe ngohlamvu "P", zixhuma amapayipi ahloselwe ukuphakamisa isilinda se-hydraulic cylinder, ezinye izimbobo zixhuma amapayipi axhuma umgodi ophansi.

Ukuze kuxhunywe i-hermetic yamapayipi, ukufakwa kuvaliwe ngama-washers ethusi namasongo enjoloba - izindlala zekhebula. Njengendinganiso, i-spool eyodwa yokusabalalisa ixhunywe kusilinda samandla we-hydraulic wokuxhumanisa ugandaganda ngemuva, futhi ama-spools amabili asetshenziselwa ukushayela imishini ye-hydraulic ekude.

Uma zingekho izingxenye ezintathu ze-distributor ye-hydraulic drive kanye nokulawula imishini, i-distributor eyengeziwe ifakwe kugandaganda. Kunezindlela ezimbili zokuxhuma: uxhumano lwe-serial kanye noxhumano oluhambisanayo.

Esimweni sokuqala, ukunikezwa kokusabalalisa kwe-hydraulic yesibili kwenziwa kusuka kwesinye sezigaba zokusabalalisa okuyinhloko okuxhuma indawo yokukhipha i-elevator nesiteshi sokukhipha sokusabalalisa kwesibili. I-outlet yokubuya kokugeleza koketshezi olusebenzayo, esetshenziswa yi-spool yomhlangano omkhulu ukuze uthole ukuhlinzekwa okwengeziwe komsabalalisi, ivaliwe ngepulaki. Umgodi wokudonsa we-distributor wesibili nawo uxhunywe ku-hydraulic tank yesistimu. I-valve icushiwe ngokubeka i-spool exhunyiwe endaweni "yokuphakamisa".
