Diki kuomarara kwepfuti peening particles kunoita kuti chirimo chepamusoro kurapwa kusapfuure;· Kuneta kutyoka kunokonzeresa 1.7% yekutadza zvachose, uye mamwe ese kuzorora kuneta.· Kuzorora kuneta kwagara riri dambudziko rinovhiringa indasitiri yechirimo.Sezvo simbi dzisiri elastomer zvachose, micro-deformation (inokambaira) ichaitika kunyangwe pasi pechiito chekushushikana pazasi peiyo elastic muganho, uye pesvedzero yekusingaperi deformation pakudonha kwekudzvanya kwejekiseni kunowanzo 0.5 Kupfuura MPa, kudonha kwekumanikidza kuri kunyanya kukonzerwa nekupfeka kwebhora resimbi kana sphere mumuswe wevharuvhu yetsono uye tsvimbo yejector, uye simba rayo pakudonha kwemhepo iri pakati pe 0.5 ne 2.5 MPa.

(2) Kupfeka gaskets dzakati sandara: (1) Magetsi akafuratira ane maburrs, anosvika 0.4mm;②Flat gasket zvinhu zvakapfava, zvakajairwa yakaderera kabhoni simbi, uye kuoma HRC47 ~ 54 chitubu chekupedzisira kubata chiri nyore kupfeka uye deformation.

(3) jacking tsvimbo.Pressure regulating screw (kana screw sleeve) uye pressure regulating screw two end face yekubata ndege inopfeka :40% yeinjector yemafuta inoratidzika kupfekeka zviri pachena pano.Pane zvikonzero zviviri:①iyo yekuonana pamusoro pekugadzirisa yakanyanya kushata, Ra 12.50 Hn, zvichikonzera kudonhedza kwekumanikidza kweanopfuura 1 MPa;(2) Ndege yekubata haina kuenzana, zvichikonzera kusaenzana kwechitubu chekupedzisira chinokonzera kupenya kwebhandi, kupfeka kudzika kwepamusoro kusvika 0.15mm.

(4) Pesvedzero yehutsanana hwejekitari yemafuta: Nekuda kwekubvisa mhedzisiro yemafuta jekiseni ekubvisa midziyo yevazhinji vagadziri vemba haigone kuenderana nezvinodiwa zvemitemo yenyika, kune imwe chiyero chebvudzi uye kugadzirisa abrasive mumuviri wejojo ​​jekiseni, uyo inokonzeresa kusapfeka zvakanaka kwemafuta jekiseni ekubatanidza zvikamu, zvichikonzera kuwedzera kweiyo fit clearance, kuderera kwechisimbiso uye kudonha kwekumanikidza.
