1. Kushanda Nheyo

Iyo pombi yemafuta yegiya ine shaft yekutyaira, giya rekutyaira, shaft inofambiswa, giya rinofambiswa, imba, nezvimwe. Magiya maviri ane nhamba yakafanana yemeno mesh kune mumwe nemumwe uye anoiswa mudzimba. Iyo radial uye yekupedzisira nzvimbo yekuchenesa pakati pegiya nedzimba idiki kwazvo. Pane mapindiro emafuta neoiri paimba yacho. Iyo shaft yekutyaira inokiyiwa kune giya rekutyaira, uye giya rinotyairwa rakaiswa maoko rakasununguka pane shaft inotyairwa. Kana injini yedhiziri ichishanda, giya rehelical pa crankshaft rinotyaira giya rekufambisa papombi yemafuta kuti ritenderere, uye giya rekutyaira mudzimba repombi yemafuta rinotyaira giya rekutenderera. Iwo magiya maviri anotenderera akatarisana, uye oiri inofamba pakati pemazino uye inoyerera ichibva painopinza mafuta ichienda kunobuditsa mafuta. Kune rimwe divi rekamuri yekupinza mafuta, nekuda kwekusabatanidzwa kwegiya uye nekuramba kubviswa kwemafuta, vacuum inogadzirwa kuti igadzire yakaderera uye ibudise kusveta, kuitira kuti mafuta ari mupani yemafuta apinde mukamuri yekupinza mafuta. kuburikidza nesefa pasi pekuita kwekumanikidzwa kwemuchadenga, uye kune rumwe rutivi rwekamuri yekuburitsa mafuta, nekuda kwekusangana kwegiya uye nekuramba kubviswa kwemafuta, kudzvanywa kwemafuta kunowedzera, uye mafuta anopombwa pane imwe dzvinyiriro uye anotsikirirwa kune friction surfaces yeimwe neimwe inofamba chikamu.

Uye zvakare, pakupera kwemeshing kweaviri magiya, nekuda kwekuvapo kweakakwira-kudzvanywa mafuta uye mukaha mudiki pakati pegiya rekupedzisira kumeso uye imba, mafuta haasi nyore kudonhedza, izvo zvinowedzera kudzvanywa pagiya shaft. , nokudaro zvichiwedzera kupfeka kweshaft uye gomba. Kuti ubvise mhedzisiro iyi, kudzoreredzwa kwekumanikidza kunowanzo kuvhurwa pachivharo chepombi kuita kuti mafuta aenderere kunzvimbo yekubuda kwemafuta pamwe nekurerutsira kwekumanikidza kuti uwane mhedzisiro yekumanikidza. Kupomba kwemafuta vhoriyamu uye kudzvanywa kwemafuta epombi yemafuta kunowedzera nekuwedzera kweinjini yedhiziri. Ivhavha yekudzivirira mafuta ine valve kana bhora uye chitubu chemhepo. Mafuta anoyamwa kuburikidza nesefa uye anotumirwa kune mafuta sefa. Kana iyo mafuta ekupa kudzvanywa ichiwedzera nekumhanya kweinjini yedhiziri, vharafu yekuyamura inovhura. Panguva ino, mafuta anopinda mudivi rekupinza kubva kudivi rekubuda kuburikidza nebypass kuchengetedza kudzvanywa kwakataurwa.

2. Mamiriro ezvinhu

Chimiro chakareruka, saizi diki, huremu huremu, uye kutakura mafuta hombe. Iyo cycloid rotor pombi inotora chimiro chemukati nekunze rotor meshing, ine nhamba diki yemazino uye compact dhizaini. Inogona kuumba chisimbiso chakavharwa pasina rubatsiro rwezvimwe zvinhu zvekuzviparadzanisa, uye ine nhamba shoma yezvikamu.

3. Mafambiro maitiro

Smooth operation uye pasi ruzha. Nhamba yemazino emukati uye ekunze rotor ye cycloid rotor pombi inosiyana nezino rimwe chete. Pavanenge vachifamba vachienda kune mumwe nemumwe, kukurumidza kutsvedza kwepamusoro pezino kwakaderera, uye meshing point inogara ichifamba pamwe chete nezino rezino remukati nekunze rotors. Nokudaro, kuwirirana kwekupfeka kwemazino emazino maviri e rotor idiki. Sezvo emvuropu yekona yekamuri yekusveta mafuta uye kamuri yekuburitsa mafuta yakakura, padyo ne145 °, kusveta kwemafuta uye nguva yekuburitsa zvakaringana, saka kuyerera kwemafuta kunenge kwakadzikama, kufamba kwakadzikama, uye ruzha rwuri. yakaderera zvakanyanya pane iyo yepombi yegiya.

4. High-speed maitiro

Kune general involute giya pombi, kana kumhanya kwakanyanyisa, mupata wemazino unozozara zvisina kukwana nemafuta nekuda kweiyo centrifugal simba, ichigadzira "cavity", iyo inoderedza kushanda kwepombi. Naizvozvo, kumhanya kwayo kashoma kudarika 3000rpm, uye circumferential kumhanya iri mukati me5-6m/s. Kune iyo cycloid rotor pombi, iyo yekukweva uye yekuburitsa angle range yakakura. Kana ichitenderera ichimhanya zvakanyanya, iyo centrifugal simba inokodzera kuzadza mafuta mumupata wemazino, uye hapana chinokuvadza "cavity" chiitiko chichaitika. Naizvozvo, iyo yekumhanya yepombi ye cycloid rotor inogona kubva kumazana akati wandei kusvika kunosvika zviuru gumi zvekuchinja.
