Pomanga kupanga tsiku ndi tsiku, excavator ndi makina omanga omwe amagwiritsidwa ntchito kwambiri, omwe amagwiritsidwa ntchito kwambiri pakufukula maziko a nyumba ndi kuyeretsa akamaliza, kuyika mapaipi am'tawuni, kusungirako madzi m'mafamu ndi nthawi zina, ndi ubwino wa zomangamanga zosinthika komanso zapamwamba. kuchita bwino. Excavator nthawi zambiri imakhala ndi chipangizo chogwirira ntchito, chipangizo chozungulira, kabati, chipangizo choyenda ndi ma hydraulic control system, zomwe sizingalephereke mu hydraulic control system kuti agwiritse ntchito valavu yothandizira, valavu yopumira mu hydraulic system makamaka imagwira ntchito ya kupanikizika kosalekeza ndikusefukira. chitetezo chitetezo. Pakalipano, valve yothandizira yomwe imagwiritsidwa ntchito pofukula ndi valve yothandizira oyendetsa ndege, monga momwe tawonetsera pa Chithunzi 1 ndi Chithunzi 2. Amapangidwa makamaka ndi kukweza mutu 1, chigawo chachikulu cha valve 2, valavu yayikulu 3, valavu yoyendetsa ndege 4, kuthamanga kwa kasupe. 5 ndi manja oyendetsa valavu 6. Mutu wokweza mutu, manja akuluakulu a valve ndi manja oyendetsa ndege amaperekedwa ndi mabowo, ndipo mafuta opanikizika amalowa muzitsulo zazikulu za valve kupyolera mu dzenje lonyowa la mutu wokweza ndikuchitapo kanthu pazitsulo zoyendetsa ndege. Pamene kupanikizika kwa dongosolo kumakhala kochepa kuposa kutsegulira kwa spool yoyamba yoyendetsa ndege, valavu yoyendetsa ndege ili mu malo otsekedwa, ndipo zokakamiza zamkati ndi zakunja za spool yaikulu ndizofanana. Chifukwa cha kusiyana kwa mkati ndi kunja, spool yaikulu imakhalabe yotsekedwa pansi pa mphamvu ya madzi; Pamene kuthamanga kwa dongosolo kuli kwakukulu kuposa kutsegulira kwa valavu yoyendetsa, valavu yoyendetsa ndege imakankhidwira kutali ndi mafuta opanikizika, ndipo mafuta othamanga amabwerera ku thanki kupyolera mu bowo la manja oyendetsa ndi bowo lalikulu la manja. Panthawiyi, kutsika kwamphamvu kumapangidwa pamene madzi akuyenda mu dzenje lonyowa la mutu wokweza, kotero kuti kupanikizika kwamkati kwa spool ya master valve ndi kwakukulu kuposa kuthamanga kwa chipinda chakunja, chomwe chimakankhira valavu yaikulu kuti itsegule, ndipo mafuta a hydraulic amabwerera ku thanki kudzera pabowo lalikulu la ma valve. Pamene kupanikizika kwa dongosolo kumatsika mpaka kutsika kwa kutsegulira kwa spool woyendetsa ndege, woyendetsa ndegeyo amatseka, ndipo pamene kusiyana kwapakati pakati pa mkati ndi kunja kwa spool yaikulu kumakhala kochepa, kutsegula kumatsekedwa pansi pa ntchito ya kukonzanso kasupe. Komabe, pogwiritsira ntchito kwenikweni, zimapezeka kuti pamene valavu yothandizira yomwe ili pamwambayi ikugwiritsidwa ntchito, valavu yoyendetsa ndegeyo iyenera kutsegulidwa ndi kutseka kawirikawiri, ndipo kutsegula ndi kutseka kwa valve yoyendetsa ndege kumatsimikizira ntchito ya valve yothandizira, kotero gawolo. za dzenje la manja oyendetsa valavu yolumikizana ndi valavu yoyendetsa ndi yofunika kwambiri. Kuti atsimikizire kukhazikika kwa magwiridwe antchito a valve yothandizira, malo opangira ma valve oyendetsa nthawi zambiri amafuna kulondola kwa makina. Bowo la manja oyendetsa ndege ndi lalitali, manja a valve oyendetsa ndege m'dera la kukonza ndi kuyesa ndizovuta kwambiri, kuwongolera kulondola n'kovuta kuonetsetsa, zomwe zimapangitsa kuti ntchito ya valve yoyendetsa ndege isatsimikizidwe bwino, kukhazikika kwa valve yothandizira kumakhala kovuta kwambiri. zomwe zimakhudzidwa, kuwonjezera apo, pachimake chachikulu cha valve ndi mkono waukulu wa valavu pakati pa coaxiality makamaka zimadalira malo oyendetsa manja oyendetsa ndege kuti atsimikizire, chifukwa manja a valve oyendetsa ndege ndiatali, Kupatuka pang'ono kwa ulusi kumakhudzanso kugwirizana kwa spool yayikulu ndi manja ake a valve, zomwe zimapangitsa kuti asasindikize bwino komanso asatayike.
