Piston neeg: cov khoom thiab apparatus
Piston pab pawg neeg - ib pab pawg neeg ntawm piston thiab sealing rings. Cia li raws li nws muaj xws li ib tug piston pin thiab mounting cov ntsiab lus. Nws yog ib nqi xav tias lub sij hawm ntawm lub mechanism.
Piston pab pawg neeg nqa tawm nws cov hauj lwm txawm nyob rau hauv hnyav tej kev kawm. Uas yog vim li cas lub ntsiab lus ntawm no mechanism muaj siab thermal zog, thiab qhov no yog coj mus rau hauv tus account thaum cov khoom thiab tsim xaiv rau lawv. Cov ntsiab yog feem ntau manufacturers tsim, muab lub hom cav thiab cov lo lus uas peb (thauj, nyob ruaj ruaj, diesel, daim ntawv, thiab lwm yam). Txawm li cas los, tag nrho cov qauv tseem tseem zoo li qub. Yog li ntawd, koj yuav tsum tau xav txog, dab tsi piston pab pawg neeg.
Lub piston lub taub hau yog piston rings thiab muaj ib tug hauv qab. Lub sab groove muaj ib tug kua qhov los ntawm kev uas ncua lub lubricating roj kom nws ho tsis poob ntawd mus rau hauv lub combustion chamber. Nws qab - qhov no yog ib tug ntawm cov chamber phab ntsa. Nws yuav siv sij hawm ntau heev siab gases. Tus heev hauv qab yuav ua tau ncaj nraim, concave, convex los yog zoo li tus. Ib zaug ntxiv, nws daim ntawv yog xaiv thaum lub hom cav sau npe, thiab lub combustion chamber.
Nws yog tsis yooj yim sua tsis hais txog ib tug mechanism xws li lub tog raj kheej-piston pab pawg neeg. Lub ntsiab tsis xws luag ntawm lub tog raj kheej thaiv - tawg, tawg thiab hnav. Cov faults yog tsim tom qab ib tug meej kev soj ntsuam, siab los soj ntsuam thiab kev ntsuas lub tog raj kheej. Nyob rau hauv tus txheej txheem no, nyob rau hauv block koj xav rau nruab lub taub hau los yog cam khwb cia-hlau phaj (obligatory roj hmab gasket). Feem ntau, qhov no pab pawg neeg txawv thaum tshav kub kub-resistant hlau thiab roj cua txias, uas yog ua li cas at the expense of zuag qhia tag nrho kev lubrication system ntawm lub ntsiab diesel cav. Yog hais tias koj muab zoo saib xyuas mechanism thiab high-zoo roj, nws yog ua tau yooj yim ua rau kom lub neej ntawm lub pistons thiab thooj voos kheej kheej.
