ʻO nā ʻāpana excavator PC300-5 PC400-5 E hoʻomalu i ka pahu hoʻomaha 709-90-52203

Loaʻa i kahi pahu hoʻomaha no ka mea ʻeli he poʻo hoʻokiʻekiʻe 11, kahi pahu pahu nui 12, kahi pahu pahu nui 13, kahi pahu pahu hoʻokele 14, kahi pūnāwai hoʻoponopono kaomi 15 a me kahi lima valve pilot. Hoʻonohonoho ʻia ka spool valve nui 12 i loko o ka lima valve nui 13, ua hāʻawi ʻia ka spool valve nui 12 me kahi poʻo hāpai 11 a me ka lima valve pilote, a ua hāʻawi ʻia ka lima valve pilote me kahi spool valve pilote 14. ʻO ia he ʻano hoʻokaʻawale ʻelua ʻāpana, i haku ʻia me kahi kino valve 16 a me kahi uhi valve 17, ua hoʻonohonoho ʻia ke kino kiwi mai ka hopena o ka pahu pahu i loko o ke kumu valve nui, ʻo ke kino kiwi kokoke i ka hopena o ka pahu pahu i hoʻohuli ʻia e hana i kahi. luna 18, me ka haku i loko o ka nui valve lima i hoʻolako 'ia me ka groove, ka lua clamping palena constitutes ka palena hale. Ke hoʻohana ʻia ka hale, no ka mea, ua māhele ʻia ka lima valve pilote i ʻelua ʻāpana kino valve 16 a me ka uhi valve 17, ua hāʻawi ʻia ka lima valve nui 13 me kahi groove, ua hāʻawi ʻia ke kino valve me ka boss 18, i hoʻohana ʻia e. hoʻoponopono i ke kino valve 16 radial a me ke axial, ua hoʻonohonoho ʻia ke kumu valve nui a me ke poʻo hoʻokiʻekiʻe i loko o ka lima valve nui, a hoʻokomo mua ʻia ke kino valve i loko o ka lua kumu valve nui i ka wā o ka hoʻokomo ʻana. E hilinaʻi i nā ʻāpana ma ka lima valve nui e kaupalena i ke kino valve axially a me radially, a laila e hoʻololi i ka pāpale valve i loko o ka lima valve nui a kaomi i ke kino valve e hoʻoponopono i ke kino valve, a laila hiki ke hoʻohana maʻamau ka pahu hoʻomaha.

1. Aia i loko o ka pahu ho'omaha ho'oku'u ke po'o ho'oki'eki'e (11), ka wili pahu nui (12), ka lima o ka pahu pahu nui (13), ka punawai ho'oponopono kaomi (15) a me ka lima o ka pahu pailaka. . Hoʻonohonoho ʻia ka spool valve nui (12) i loko o ka lima valve nui (13), a ua hāʻawi ʻia ka spool valve nui (12) me ke poʻo hāpai (11) a me ka lima valve pilot. Hāʻawi ʻia ka lima valve pilote me kahi kumu valve pilote (14), ʻo ia ka mea i ʻike ʻia ʻo ka lima valve pilot he ʻano māhele ʻelua ʻāpana, i haku ʻia me kahi kino valve (16) a me kahi uhi valve (17), ka valve kino (16) mamao mai ka uhi kiwi (17) hoʻonohonoho ʻia kekahi wēlau i loko o ka pahu pahu nui (12), ʻO ke kino kiwi (16) kokoke i ka uhi kīwila (17) - ua hoʻopili ʻia ka hopena me ka lima pahu nui (13). ) ma o ke kūkulu palena ʻana.
2. Wahi a ka ʻōlelo 1, ua ʻike ʻia kahi pahu hoʻomaha excavator i ka hopena o ke kino valve (16) kokoke i ka uhi valve (17) i lilo i haku (18), a ua hāʻawi ʻia ka haku i kahi ʻāpana i loko. ʻO ka lima valve nui (13), a ʻo nā palena pipili ʻelua ke ʻano o ka hana palena.
Hōʻike ka hiʻohiʻona pono i kahi pahu hoʻomaha no ka excavator, me kahi poʻo hāpai, kahi pahu pahu nui, kahi lima valve nui, kahi pahu pahu pilote, kahi puna hoʻoponopono kaomi a me kahi lima valve pilot, ua hoʻonohonoho ʻia ke kumu valve nui i loko o ka pahu nui. ʻO ka lima valve, ua hāʻawiʻia ka pahu valve nui me ke poʻo hoʻokiʻekiʻe a me ka lima valve pilote, ua hāʻawiʻia ka lima valve pilote me kahi pahu pahu pilote, kahi iʻikeʻia i loko o ka lima o ka pahu pilo pilo he papa hoʻokaʻawaleʻelua. Hoʻokumu ʻia me kahi kino valve a me ka uhi valve, ua hoʻonohonoho ʻia ke kino kiwi mai ka hopena o ka pahu pahu i loko o ke kumu valve nui, ʻo ke kino valve kokoke i ka hopena o ka pahu valve ma o ka hoʻolālā palena a me ka pili kūloko lima valve nui. Hoʻokaʻawale ke kumu hoʻohālike i ka lima valve pilote i loko o ke kino valve a me ka uhi valve, a laila e hōʻemi ana i ka lōʻihi o ka lua o loko o ka lima valve pilote, e hoʻomaikaʻi ana i ka pololei o ka hana ʻana o ka ʻāpana pili ma waena o ka lima valve pilote a me ke kumu pahu pilote, a pēlā e hoʻomaikaʻi ai i ka paʻa o ka pahu hoʻomaha.
