ʻO ke kiʻekiʻe kiʻekiʻe ʻo Diesel injection pump Plunger 2425-988 Fuel Plunger Element Plunger 2425 Series

ʻAʻole hiki i ka axial piston pump me ka triangular groove plate kuʻuna ke hoʻopau loa i ka pulsation kaomi i hoʻokumu ʻia e ka commutation i ka wahi hoʻololi, a e hoʻopuka i kahi ʻano kahe backflow ma muli o ka mana o ka throttling. I ka loaʻa ʻole o ka hoʻolālā subversive o ka cylinder block a i ʻole valve plate, ua manaʻo ʻia e hoʻopili ʻia kahi hoʻonohonoho ʻana o ka puʻupuʻu reciprocating valve e hui pū ʻia ma waena o kēlā me kēia lua plunger, i mea e pale ai i ka puʻuwai puʻupuʻu i ka wahi hoʻololi, e hoʻemi i ka haʻalulu i ka wahi hoʻololi. , a hoʻopau i ka hana triangular groove o ka valve plate, i mea e hoʻemi ai i ke kahe hope. Hāʻawi ʻia i ke anawaena a me nā ʻāpana ʻē aʻe o ka valve reciprocating, ʻike ʻia ma o ka simulation ʻo ka puʻuwai puʻupuʻu i hana ʻia e ka hale ma ka wahi hoʻololi he 2.5% wale nō, hiki ke hoʻemi pono i ka puʻuwai puʻuwai o ka axial piston pump i ke kaʻina hana kiʻekiʻe. a me ka wahi hoʻololi puʻe haʻahaʻa i hoʻohālikelike ʻia me ka pā kīpē triangular groove.

Ke kuhi nei i nā pilikia e like me ka lawa ʻole o ka helu hāpana a me nā hiʻohiʻona hewa nāwaliwali o ka hōʻailona leo i ka ʻike hewa ʻana o ka paila piston, A Fault Diagnosis of Plunger Pump Based on MTL (McL-pafd) ma muli o nā leo leo i hui pū ʻia me Meta-transfer Learning (MTL) ua noi ʻia. Ma kēia ʻano, lawe ʻia ka hōʻailona leo o ka plunger pump e like me ka laʻana, a ua hana ʻia ka hōʻailona e ka waihona kānana Gammatone ma lalo o ke kūlana o kahi sensor hoʻokahi, hiki ke hoʻomaikaʻi maikaʻi i ka hiki ke hoʻohālikelike ʻia o ka hōʻailona leo ma lalo o ka hoʻopilikia ʻana i ka leo ikaika. . A laila, hui pū ʻia me ke aʻo ʻana i ka meta transfer, hiki ke ʻike ʻia ka ʻike hewa o ka paila plunger ma lalo o ke ʻano o ka laʻana liʻiliʻi. I ka manawa like, e like me nā pono maoli o ka ʻike hewa o ka plunger pump, ua hoʻomaikaʻi ʻia ke ʻano hoʻāʻo o ke aʻo ʻana i ka meta-transfer i ka noi ʻike hewa, a hiki ke hoʻoponopono ʻia ka papa hewa ʻike ʻole. Hōʻike nā hualoaʻa hoʻokolohua hiki i ka pololei o ka hōʻailona McL-pafd ke hiki i 91.41% wale nō no nā papa hewa i ʻike ʻia, akā ma hope o ke aʻo ʻana wikiwiki, hiki i ka pololei o ka hōʻailona McL-pafd ke hiki i 89.64% ke ʻike i nā papa hewa ʻike ʻole.
