High Performance Delivery Valve K15 for Injection Pump Diesel Engine Spare Parts for ISUZU KUBOTA ISEKI

1. Chimiro chevhavha yekuendesa

(1) Ivhavha yekutakura oiri uye chigaro chevharuvhu zvikamu zvechokwadi, zvakagadzirwa nesimbi yemhando yepamusoro. Maburi avo ekutungamira, ekumusoro neazasi kumagumo zviso uye makomba ezvigaro akanyatsogadziriswa uye pasi, uye haagone kuchinjika mushure mekubatana.

(2) Chikamu chekoni chevhavha yekubuda kwemafuta ndiyo axial sealing cone pamusoro pevhavha. Chikamu chekoni chevharuvhu chinotsvedza mugomba rekutungamira uye chinoita basa rekutungamira. Muswe wacho wakagadzirwa nema grooves kuti uite cross-section kuti mafuta apfuure. Iyo cylindrical pamusoro pepakati peivhavha yekutakura mafuta inonzi decompression zone, iyo inoumba decompression volume ine chisimbiso cone pamusoro.

(3) Nzvimbo yepasi yekupedzisira yechigaro chevharuvhu uye yekumusoro kwekumusoro kweiyo plunger sleeve inogadzirwa nemashini uye yakanyatsoiswa. Ivo vanosimbiswa neiyo compression nati ine yakatsanangurwa inosimbisa torque. Pane copper high-pressure sealing washer yeimwe ukobvu pakati pe compression nati nechigaro chevharuvhu. Iko kune zvakare yakaderera-kudzvanywa chisimbiso gasket pakati pemafuta ekutumira valve compression nati uye yekumusoro kumagumo kweimba.

(4) Chigadziko chinodzikisira chakaiswa mukati memukati meiyo oiri yekusvitsa valve compression nut kuti ideredze vhoriyamu yemukati mhango nzvimbo, kukurudzira kukurumidza kumira jekiseni, uye kudzikisira kukwirisa kwevhavha yekubuda kwemafuta.

2. Basa revhavha yekuendesa

(1) Dzivirira kudonha mafuta pamberi pejekiseni uye wedzera kumhanya kwejekiseni: Kana pombi yejekiseni ichipa oiri, mushure mekudzvanywa kweoiri kwakakwira kupfuura simba rekurodha revharuvhu yekuunza mafuta uye kudzvanywa kwakasara mupombi yemafuta ekumanikidza, vharafu yemafuta Ivhavha yemafuta inosimuka uye koni yayo yekuvharisa inosiya chigaro chevharuvhu. Izvo zvinodikanwa kumirira kusvikira bhandi rekumanikidza pavhavha yekutakura mafuta richisiya zvachose gomba rekutungamira rechigaro chevhavha pamberi pemafuta ari mukamuri yepombi yepombi inogona kupinda mupombi yemafuta.

(2) Dzivirira kudonha kwemafuta mushure mejekiseni uye wedzera kumhanya kwekuvhara: Kana mafuta akamira, panongoperera mupendero webhandi rekudzikirira revhavhavha yekubuda kwemafuta pakupinda mugero, nzira iri pakati pepombi yemafuta. uye kamuri yepombi yakagurwa. Kana iyo valve yekutakura mafuta yakagara zvachose, inodonha chinhambwe h, saka huwandu hwepombi yemafuta yepamusoro inowedzerwa, zvichiita kuti mafuta emafuta adonhe nekukurumidza ne1MPa ~ 2MPa, uye mafuta anotemwa nekukurumidza uye nyore, kudzivirira kuchinja kwemafuta uye "pipe shrinkage" kubva mukukonzera mafuta kukwira. "Uye gadzira mafuta anodonha mushure mekupfapfaidza. (3) Dzivirira mafuta kubva pakuyerera kumashure uye chengetedza imwe yakasara kudzvanywa mupombi yemafuta inodzvanywa.
