zindikirani!Kodi zolakwika zomwe zimachitika nthawi zambiri mukayika ma hydraulic breaker pa zofukula?

Kodi mukudziwa mfundo yogwirira ntchito pambuyo pokonzekera?

Pambuyo pakuyika kwa hydraulic breaker pa chofufutira, ngati chowotcha cha hydraulic sichingakhudze magwiridwe antchito a zida zina zofukula. Mafuta oponderezedwa a hydraulic breaker amaperekedwa ndi mpope waukulu wa excavator. Kuthamanga kwa ntchito kumayendetsedwa ndikuyendetsedwa ndi valve yothamanga. Kuti muthe kusintha magawo a hydraulic system, cholowera ndi chotuluka cha hydraulic breaker chiyenera kukhala ndi valavu yoyimitsa kwambiri.

Zolakwa ndi mfundo zofala

Zolakwika zodziwika: valavu yogwira ntchito ya hydraulic breaker yavalidwa, mapaipi amaphulika, ndipo mafuta a hydraulic amatenthedwa kwambiri.

Chifukwa chake n'chakuti luso silinakonzedwe bwino, ndipo kulamulira pa malo sikuli bwino.

Chifukwa: Kuthamanga kwa wosweka nthawi zambiri kumakhala 20MPa ndipo kuthamanga kwapakati kumakhala pafupifupi 170L / min, pamene kupanikizika kwa makina ofufutira nthawi zambiri ndi 30MPa ndipo kuthamanga kwa mpope umodzi waukulu ndi 250L / min. Chifukwa chake, valavu yakusefukira imanyamula katundu wosokoneza. Valve yoyenda idawonongeka ndipo sinapezeke munthawi yake. Chifukwa chake, chophwanya ma hydraulic chidzagwira ntchito movutikira kwambiri, zomwe zimabweretsa zotsatirazi:

1: Kuphulika kwa mapaipi, mafuta a hydraulic amatenthedwa kwanuko;

2: Valavu yayikulu yowongolera imavalidwa kwambiri, ndipo gawo la hydraulic la ma spools ena a gulu lalikulu la valavu yofukula amadetsedwa;

3:Kubwerera kwamafuta kwa hydraulic breaker nthawi zambiri kumadutsa mozizira. Fyuluta yamafuta imabwereranso ku thanki yamafuta, ndipo imazungulira kangapo motere, kupangitsa kuti kutentha kwamafuta kukhale kokwera, zomwe zimachepetsa kwambiri moyo wautumiki wa zida za hydraulic.

Njira zothanirana nazo

Njira yothandiza kwambiri yopewera zolephera pamwambapa ndikuwongolera ma hydraulic circuit.

1. Ikani valavu yodzaza kwambiri pa valavu yayikulu yobwerera. Kupanikizika kokhazikika kumakhala bwino kukhala 2 ~ 3MPa wamkulu kuposa valavu yothandizira, kuti achepetse kukhudzidwa kwa dongosolo ndikuonetsetsa kuti kupanikizika kwa dongosolo sikudzakhala kwakukulu kwambiri pamene valavu yothandizira ikuwonongeka. .

2.pamene kutuluka kwa mpope waukulu kumadutsa nthawi 2 kuchuluka kwa kuthamanga kwa wosweka, valve ya diverter imayikidwa kutsogolo kwa valavu yaikulu yotsitsimutsa kuti achepetse katundu wa valve yowonjezera ndikuletsa kutentha kwapakati.

3. Lumikizani mzere wobwereranso wamafuta wa dera logwira ntchito lamafuta kutsogolo kwa choziziritsa kukhosi kuti muwonetsetse kuti kubwerera kwamafuta ogwirira ntchito kwakhazikika.
