Chii chinonzi chimiro chepombi yedhaka?

Petroleum muchina wakakwira-kudzvanya madhaka pombi inonyanya kuumbwa nezvikamu zvinotevera:

(1) Kupera kwesimba

1. Chivharo chepombi uye chifukidziro chepombi chakagadzirwa nesimbi mahwendefa uye zvakabatanidzwa pamwe chete.

Chigaro chinotakura chekutyaira shaft uye crankshaft ndeye yakakosha simbi yekukanda. Mushure mekugadzirisa, inounganidzwa uye yakasungirirwa negomba repombi. Mushure mekuputika, inogadziriswa kubvisa kusara kunetseka.

2. Kutyaira shaft

Zviyero zvezvikamu zvakatambanudzwa kumagumo ese epombi yedhaka yekufambisa shaft yakanyatso symmetrical, uye mahombe kana sprockets anogona kuiswa kune chero kumagumo. Mabhengi anotsigira pamativi ese ari maviri anotora imwe-mutsara radial stub roller mabhengi.

3. Crankshaft

Iyo inotora yakaumbwa yakatwasuka shaft plus eccentric chimiro pachinzvimbo chechinyakare chakabatanidzwa chakakandwa crankshaft chimiro chetatu-cylinder pombi kumba nekune dzimwe nyika. Inoshandura iyo yekukanda kuita yekugadzira uye yese kuita musangano, iri nyore kushandisa, iri nyore kugadzira uye nyore kugadzirisa. Iyo eccentric vhiri, hombe herringbone giya hub uye shaft inotora kukanganisa kunokodzera.

(2) Mvura inopera

1. Bhokisi revhavha: yakakosha kuumba chimiro chakatwasuka chine vhoriyamu yemvumo ye7.3 malita chete. Iyo pombi yekuchera yakatevedzana ine diki diki yekubvisa vhoriyamu pakati pemba-yepamusoro-simba madhaka pombi. Iwo matatu mabhokisi evharuvhu anoona kuburitsa uye kusveta kuburikidza nekuyerera kwakawanda uye nekusveta manifold. Imwe magumo ekubuda manifold yakashongedzerwa ne-high-pressure four-way uye discharge pre-pressurized air bag, uye imwe mugumo ine lever-type shear safety valve.

2. Cylinder liner: Shandisa bimetallic cylinder liner, iyo yemukati yemukati zvinhu yakakwira chromium kupfeka-resistant alloy, iyo yemukati roughness inodiwa kuti ive mukati meiyo 0.20, uye mukati mukati mekuoma kwemukati ndeye ≥HRC60. Iyo humburumbira liner zvinotsanangurwa zviri pakati nepakati 100-pakati 100. kuti vashandisi vasarudze.
