ʻO ka paʻakikī liʻiliʻi o nā ʻāpana peening pana ʻaʻole i hala ka lapaʻau ʻana o ka punawai;· ʻO ka haʻihaʻi luhi ma kahi o 1.7% o ka nui o nā hemahema, a ʻo ke koena he hoʻomaha luhi.· He pilikia mau ka hoʻomaha hoʻomaha ʻana i ka ʻoihana puna.No ka mea, ʻaʻole i elastomer loa nā metala, hiki mai ka micro-deformation (creep) ma lalo o ka hana o ke koʻikoʻi ma lalo o ka palena elastic, a ʻo ka hopena o ka deformation mau loa ma ka hāʻule kaomi ʻana o ka injector ma ke ʻano he 0.5 Ma waho aʻe o MPa, ʻo ka hāʻule ʻana o ke kaomi. ʻO ka mea nui ma muli o ka ʻaʻahu ʻana o ka pōpō kila a i ʻole ka pōʻai i ka huelo o ka valve needle a me ke koʻokoʻo ejector, a ʻo kona mana i ka hāʻule kaomi ma waena o 0.5 a me 2.5 MPa.

(2) Hoʻohana i nā gaskets palahalaha: (1) Loaʻa i nā pahu paʻa nā burrs, a hiki i ka 0.4mm;②He palupalu nā mea hoʻoheheʻe paʻa, kila haʻahaʻa haʻahaʻa haʻahaʻa, a me ka paʻakikī HRC47 ~ 54 punawai hopena maʻalahi e ʻaʻahu a me ka deformation.

(3) koʻokoʻo jacking.ʻO ka wili hoʻoponopono kaomi (a i ʻole ka lima wili) a me ka wili hoʻoponopono kaomi ʻelua ʻaʻahu o ka mokulele hoʻopili maka: 40% o ka injector wahie ʻike ʻia ke aahu ma aneʻi.ʻElua kumu:①ʻoʻoleʻa loa ka hoʻoili ʻana i ka ʻili, Ra 12.50 Hn, e hopena i ka hāʻule o ke kaomi ma mua o 1 MPa;(2) ʻAʻole kūlike ka mokulele hoʻopili, ka hopena i ke alo o ka hopena punawai e ʻaʻahu ai i ke kāʻei ʻālohilohi, e komo i ka hohonu a hiki i ka 0.15mm.

(4) Ka hopena o ka maʻemaʻe o ka wahie injector: No ka mea ʻaʻole hiki i ka hopena deburring o ka wahie injector deburring lako o nā mea hana hale he nui i hiki ʻole ke hoʻokō i nā koi o nā kūlana ʻāina, aia kekahi nui o ka lauoho a me ka hana ʻana i ka abrasive i loko o ke kino injector wahie, ka mea. ke kumu o ka hoʻohana ʻole ʻia o nā ʻāpana hoʻohui i ka wahie injector, e alakaʻi ana i ka hoʻonui ʻana o ka hoʻomaʻemaʻe kūpono, ka hōʻino ʻana o ka sila a me ka hāʻule ʻana o ke kaomi.
