Kungotchula valavu yaikulu yothandizira, chidziwitso choyamba cha abwenzi onse a makina ndi chakuti valavu ndi yofunika kwambiri, ndipo zolephera zambiri zovuta kwambiri zimachitika chifukwa cha kusagwirizana kwa valve yaikulu yothandizira, koma udindo wapadera ukhoza kukhala wofunika kwambiri kwa aliyense. zachilendo.
Mwachitsanzo, mwina mwakumanapo chodabwitsa kuti galimoto lonse ndi ofooka ndipo liwiro ndi wodekha kwambiri pa ntchito ya excavator. Nthawi zina chitoliro chamafuta chothamanga kwambiri chimaphulika, ngakhale chikasinthidwa ndi china chatsopano. Ndipotu, "wolakwa" wa mavutowa Ndiwo valavu yaikulu yothandizira!
Ntchito yayikulu ya valve yothandizira:
Mu hydraulic system, valve yaikulu yothandizira imagwiritsidwa ntchito pokonza ndi kuchepetsa kupanikizika kwa dongosolo kuti ateteze dongosolo lonse la hydraulic kuti lisawonongeke. Imayikidwa pa valavu yaikulu yolamulira (wogawa) ndi mawonekedwe a cylindrical ndipo pamwamba pa valavu yaikulu yothandizira ilipo kusintha kwazitsulo za Hexagon, zosiyana ndi ma valve ena otetezera (valavu yowonjezera yowonjezera), pali mtedza wokhazikika pamwamba pa valavu yayikulu yothandizira.
Mphamvu yayikulu ya valve yothandizira imachokera ku pampu ya hydraulic, ndiyeno valavu yayikulu yothandizira imayang'anira kuthamanga kwa dongosolo, ndikuyenderera ku silinda iliyonse kapena mota kudzera mu valavu yayikulu yowongolera kuti izindikire chitetezo cha dongosolo lonse la hydraulic ndi magwiridwe antchito a chofukula. .
Kulephera kwakukulu kwa valve:
① Machubu othamanga kwambiri nthawi zambiri amaphulika, ndipo chubucho chimaphulika pambuyo polowa m'malo mwa chubu chatsopanocho. Ngati chodabwitsa ichi chikuchitika, m'pofunika kuyang'ana kuthamanga kwakukulu kwa kusefukira kwa excavator.
Kuthetsa! Kawirikawiri, chodabwitsa ichi chimayamba chifukwa cha kuphulika kwa chitoliro chifukwa cha kupanikizika kwakukulu kwakukulu kwa hydraulic system of excavator, ndipo ikhoza kuthetsedwa malinga ngati valavu yaikulu yothandizira imachepetsedwa mpaka kupanikizika koyenera.
②Chofufutira chimakhala chofooka ndipo liwiro limakhala lochedwa kwambiri panthawi ya ntchito. Chochitika cholephera ichi ndi kulephera kwafupipafupi kwa chofukula, kawirikawiri chifukwa cha kupanikizika kwa dongosolo lochepa, valavu yaikulu yowonongeka imatsekedwa ndi zonyansa, kapena valavu yaikulu ya kusefukira imavalidwa kwambiri. Chotsatira chake, kuthamanga kwa magazi kumachepetsedwa, ndipo kupanikizika kwakukulu kwa kusefukira kumachepetsedwanso, ndipo chofukulacho chidzakhala chofooka komanso chochepa.
Kuthetsa! Nthawi zambiri, izi zimachitika, ndipo zimatha kupasuka ndikutsukidwa pang'ono, ndikusinthidwa ngati zili zovuta kwambiri.
Kusintha kwakukulu kwa valve:
Mukakonza, gwiritsani ntchito wrench kumasula mtedza womangirira (C) pachithunzichi, tembenuzirani mtedza wosintha (D) molunjika, kupanikizika kumawonjezeka, ndipo kusinthasintha kozungulira kozungulira kumachepa. Mutatha kulimbitsa nati, yesaninso kutsimikizira ngati kupanikizika kwapakati pambuyo pa kusintha kuli koyenera (Kuyeza kuthamanga kumayenera kuikidwa panthawi yosintha).
Chidule:
Malinga ndi nkhani yomwe ili pamwambayi, aliyense wapezanso chofukula chomwe chakhala chikuvutitsidwa kwa nthawi yayitali, galimoto yonseyo ndi yofooka, liwiro limakhala lochepa kwambiri, ndipo chifukwa cha kuphulika kwa chitoliro kawirikawiri. Chotsatira ndicho kuyang'ana ndi kusintha, koma chifukwa valavu yaikulu yothandizira ili mu hydraulic system Gawo lofunika kwambiri lolondola, choncho samalani pamene mukukonzekera!
