Hoʻohana ʻia ka pahu hoʻomaha hoʻomaha CBBA-LHN

Hoʻohana nui ʻia ʻo Truck crane, kahi kaʻa multi-purpose, kaulana i ka mākeke kaʻa kūikawā, ʻo kāna mau mea nui ka chassis o ka kaʻa kūikawā a me ka hoʻouka ʻana, ma o ka neʻe ʻana o ka mīkini e like me ka amplitude, hoʻonui, rotation, hāpai e hoʻokō i ka hana mechanical o ka crane kalaka, ma o nā hui like ʻole e hoʻokō i nā hana hāpai. Aia kekahi ʻāpana kaulike i loko o ka ʻōnaehana hydraulic o ka crane, hiki ke pāʻani i ka hana palena wikiwiki i ka hāʻule ʻana o ka crane, ka lima hoʻonui a me ka lima contraction, hiki ke pale i ka nalowale o ka mana i ke kuhikuhi o ka mea kaumaha. , a hoʻopaʻa paʻa i ka mea kaumaha a me ka lima hāpai ma kekahi kūlana ma ke ākea.
Hiki i ka pahu kaulike ke pāʻani i ka hana palena wikiwiki i ka crane: i ka wā e hāʻule ai ka mīkini crane a i ʻole ka ukana, hiki i ka valve sequence i ka valve balancing ke hoʻohana i ke koena o ka valve core e mālama i kahi kūlana paʻa o ka hoʻihoʻi ʻana o ka ʻaila o ka cylinder hydraulic, no laila e mālama ka cylinder hydraulic i ka holo like, i mea e loaʻa ai ka wikiwiki o ka hāʻule ʻana, pono ka ʻōnaehana hoʻolālā e hoʻolohe i nā helu ʻelua: ʻO ka mea mua, i mea e mālama ai i nā kumukūʻai, kahi pahu hoʻopaʻa maʻalahi a me kahi pahu leakage sequence i waho. hoʻohana ʻia e pani i ka pahu kaulike. ʻO kēia no ka mea ʻoiai ʻo ka valve kaulike he hui pū ʻana o ka valve ala hoʻokahi a me ka valve sequence type leakage kūloko i waho, ua hoʻohui ka valve sequence i kahi pūnāwai papalua, nā lua hoʻoheheʻe a me nā mea hana ʻē aʻe e hana i ka valve core shock absorber. ; 'O ka lua, 'o ia ka ho'opili 'ana i ka 'aila kaapuni o ka valve kaulike ma ka mo'o i ka pahu throttle, no laila 'o ka hana spool o ka valve sequence he "sluggish", a 'a'ole ho'ololi 'ia kona wikiwiki no ka ho'ololi li'ili'i o ke kaomi o waho.
