Molao-motheo oa ho khanna oa Excavator crawler

Tsela ea ho tsamaisa motlakase:

Enjene ea diesel — coupling — hydraulic pump (matla a mochini a fetoloa matla a haeteroliki) — valve ea kabo — enjene ea rotary e bohareng — enjene ea ho tsamaea (matla a haeteroliki a fetoloa matla a mochini) — lebokose la phokotso — mabili a koloi — seporo sa ketane ea seporo -

ho fihlella ho tsamaya

Boitsebiso bo eketsehileng:

1. Rotary motion transmission route: enjene ea diesel—coupling—hydraulic pump (matla a mochine a fetoloa matla a hydraulic)—valve—slewing motor (matla a hydraulic a fetoloa matla a mechine)—lebokose la phokotso—bearing ea ho bola—ho elelloa hoa fetoha.

2. Tsela ea phetisetso ea boom: enjene ea diesel - coupling - hydraulic pump (matla a mochini a fetoloa matla a hydraulic) - valve ea ho tsamaisa - boom cylinder (matla a hydraulic a fetoloa matla a mochini) - ho phethahala ha boom movement.

3. Tsela ea phetisetso ea lithupa: enjene ea diesel—coupling—hydraulic pump (matla a mochine a fetoloa matla a haeteroliki)—valve ea kabo—silindara ea thupa (matla a haeteroliki a fetoloa matla a mechine)—motsamao oa lithupa oa phethahala.

4. Tsela ea phetisetso ea linkho: enjene ea diesel - coupling - hydraulic pump (matla a mochini a fetoloa matla a hydraulic) - valve ea kabo - silinda ea nkho (matla a hydraulic a fetoloa matla a mochini) - motsamao oa nkho oa phethahala

Molao-motheo oa ho khanna oa sekhasa sa excavator:

Crawler (wheel) hydraulic motor motor e na le lebelo le phahameng la hydraulic motor, brake, planetary reducer, valve group, joalo-joalo E khannoa ke khetla 'me e ka hokahanngoa ka kotloloho le lebili kapa lebili la ho khanna la crawler, le tšepahalang ebile le sebetsa hantle. .E amohela moralo oa matla a phahameng a tapered roller bearing, e leng se etsang hore e be le bokhoni bo feletseng ba ho jara matla a axial le radial a hlahisoang ke moepolli nakong ea mosebetsi le ho reteleha.

Lipompo tsa oli tsa Hydraulic li kenyelletsa lipompo tsa vane, lipompo tsa gear, lipompo tsa plunger le lipompo tsa screw.Lipompo tsa Vane, lipompo tsa gear le lipompo tsa plunger hangata li sebelisoa 'marakeng.The vane pompo e ka aroloa ka pompo ea vane e feto-fetohang, pompo ea dissipation e feto-fetohang, pompo ea vane e nang le pompo e pholisang le pompo ea quantitative vane.

Pompo ea oli ea hydraulic e entsoe ka likarolo tse 'ne:' mele oa pompo, tanka ea mafura e khutlonnetsepa, sebano sa khatello le hose e lohiloeng ka terata e phahameng ea khatello e phahameng., e matlafatsang tsamaiso eohle ea haeteroliki.Mefuta ea meralo ea lipompo tsa hydraulic hangata e kenyelletsa lipompo tsa gear, lipompo tsa vane le lipompo tsa plunger.Ho na le mefuta e meraro ea manonyeletso a pompo ea oli ea hydraulic: mofuta o otlolohileng, mofuta oa ho itiisa le motsoako o potlakileng.

Se latelang se hlalosa pompo ea vane, pompo ea gear, pompo ea plunger.1. Sebopeho se hakantsoeng sa pompo ea gear:

Sebopeho sa eona sa mantlha ke hore likere tse peli tsa boholo bo lekanang le letlooeng 'me lia potoloha ka har'a ntlo e kentsoeng ka thata.Bokahare ba ntlo bo tšoana le sebopeho sa "8", 'me likere tse peli li kentsoe kahare.mmele o lekana hantle.Thepa e tsoang ho extruder e kena bohareng ba likere tse peli boema-kepeng ba ho hula, e tlatsa sebaka, e tsamaea haufi le lesapo ka ho potoloha ha meno, 'me qetellong ea tsoa ha meno a mabeli a le letlooeng.

2. Sebopeho se hakantsoeng sa pompo ea vane:

E entsoe ka rotor 1, stator 2, vane 3, poleiti ea kabo ea oli le sekoaelo sa ho qetela.Sebaka se ka hare sa stator ke cylindrical bore.Ho na le eccentricity pakeng tsa rotor le stator.

3. Sebopeho se hakantsoeng sa pompo ea plunger:

Likarolo tsa sebopeho li kenyelletsa lebili la eccentric, plunger, spring, cylinder block le li-valve tse peli tsa tsela e le 'ngoe.Ho thehoa molumo o koetsoeng pakeng tsa plunger le cylinder bore.Ha lebili la eccentric le potoloha bakeng sa mothinya o le mong, plunger e ea holimo le tlase hanngoe, ho ea tlase ho monya oli, 'me ho ea holimo ho ntša oli.
