Yintoni indima ye-excavator Idler?

I-1- Uxinzelelo lwempompo oluphambili luphantsi
PC200-6 excavator wamkela ipleyiti swash kabini uhlobo axial variable piston impompo.Ukugcinwa kwe-Excavator kunye nokulungiswa Kwiimeko eziqhelekileyo, uxinzelelo lwe-oyile ye-oyile yepompo ephambili inkulu okanye ilingana ne-30 encinci ye-MP.

Ukuba ubungakanani bokunxitywa phakathi kwe-plunger yempompo engundoqo kunye nomzimba we-cylinder okanye phakathi kobuso besiphelo somzimba we-cylinder kunye nepleyiti yevalve idlula umgangatho (umsantsa phakathi kwe-plunger kunye nomzimba we-cylinder kufuneka ube ngaphantsi kwe-0.02, kwaye i-valve plate Umsantsa phakathi kobuso besiphelo somzimba we-cylinder kunye nepleyiti yevalve kufuneka ibe ngaphantsi kwe-0.02).Indawo yoqhagamshelwano ayifanele ibe ngaphantsi kwe-90%), eya kubangela ukuba uxinzelelo oluphumayo lwempompo ephambili lube luphantsi, oluya kubonakaliswa kwisixhobo esisebenzayo somatshini, kwaye umatshini wonke uya kukwazi ukusebenza.

I-2- Iqela eliphambili le-valve yokulawula ukuphuma kwempompo inempazamo
Kwimeko yokuba amandla epompo engundoqo kunye ne-injini inokudityaniswa ngokufanelekileyo kwaye indima ye-injini ingasetyenziswa ngokupheleleyo, ukuhamba kwemveliso yempompo ephambili yomatshini itshintsha ngokutshintsha kwamandla enjini.Ukuba iqela levalve yokulawula elisetyenziselwa ukunyenyisa ukuphuma kokuphuma kwempompo engundoqo ayiphumelelanga, ukuba i-PLS impendulo loop ixhunyiwe, i-spool yevalve ye-LS ibambekile, i-spool ye-valve ye-PC ibambekile, okanye i-coil yangaphakathi ye-P ° C-EPC I-valve ye-solenoid iyatshiswa Kwezinye iimeko, impompo ephambili iya kuhlala ikwimeko yokuhamba rhoqo.

Ukuba impompo ephambili ihlala ikwimo encinci yokuhamba, umatshini uya kuba buthathaka kwaye ucothe xa usebenza:
Ngokufanayo, ukuba ipleyiti ye-swash, i-servo piston kunye nezinye iindawo zempompo eziphambili ezilawula ngokuthe ngqo utshintsho lokuhamba kompompo oyintloko lubambekile, ukuphuma kokuphuma kompompo oyintloko akuyi kutshintsha.

I-3- Ukukhutshwa koxinzelelo lokulawula nge-valve yokunciphisa uxinzelelo iphantsi
Ngaphantsi kweemeko eziqhelekileyo, i-valve yokunciphisa i-valve yenkampani yokugcina i-excavator e-Chongqing inokunciphisa kwaye izinzile uxinzelelo lwe-oyile yokuphuma kwepompo ephambili kwi-3.3P, yenza i-oyile yokulawula uxinzelelo.Ukuba i-push spool kwivalve yokunciphisa uxinzelelo ayivalwanga ngokuqinileyo ngenxa yokuba i-oyile imdaka kakhulu, uxinzelelo oluphumayo lwevalve yokunciphisa uxinzelelo luya kuba ngaphantsi kwe-3.3MPā.Ngeli xesha, kungakhathaliseki ukuba isibambo sokusebenza sihamba njani, uxinzelelo lweoyile yokulawula luhlala luphantsi, kwaye ukuhamba kwe-spool ye-valve yolawulo oluphambili lwezixhobo zokusebenza ezahlukeneyo kuncinci, okubangelwa ukuhamba okuncinci kwisixhobo somsebenzi, okubangelwa ukungabi namandla kwawo wonke umatshini.

I-4-Uxinzelelo lokunciphisa i-valve enkulu yokunceda
Ivalve engundoqo yokunceda enamandla aphantsi inciphisa uxinzelelo oluphezulu lwenkqubo yonke ye-hydraulic ukuya kwi-32.5MP.Uxinzelelo oluphezulu oludlula umlinganiselo, i-valve enkulu yokunceda iya kuvula ukukhulula uxinzelelo.I-Hitachi Excavator Repair Inkampani yeChongqing iya kukhusela inkqubo kumonakalo.Ukuba umngxuma omncinci kwi-spool ye-valve yokunceda ivaliwe ngenxa yomgangatho ophantsi we-oyile kunye ne-spool ngokuqhelekileyo ivulekile, okanye uxinzelelo olusetelweyo lwe-valve enkulu yokunceda luphantsi, uxinzelelo lwangempela luya kuba luphantsi, oko kukuthi, inkqubo. Uxinzelelo luphantsi.

5- Ivalve yokukhulula ayilungile
Xa umqhubi eqala i-injini kwaye ebeka i-lever yokusebenza ngokungathathi hlangothi, i-oyile ye-hydraulic ephuma kwipompo engundoqo ibuyela ngokuthe ngqo kwitanki yamafutha ngevalve yokukhulula, kwaye uxinzelelo lokukhulula yi-3MP.Ukuba i-spool ye-valve yokukhulula ayivalwanga ngokuqinileyo ngenxa yeoli engcolileyo, i-oyile ephumayo yepompo enkulu iya kudlula i-valve yokukhupha ngokuthe ngqo kwi-tank yeoli xa umatshini usebenza.Xa i-O-ring seal kwi-valve yomthwalo esetyenziselwa ukuthintela uxhulumaniso phakathi kwe-oyile yoxinzelelo lwe-PS kunye netanki yeoli yonakaliswe, iya kubangela ukuba i-oyile ye-hydraulic pump iphinde ibuyele kwi-oyile ngqo.

I-6-LS i-valve yokudlula iphosakele
Ivalve ye-LS ye-bypass inokuvuza inxalenye ye-P15 ye-oyile yoxinzelelo kwisekethe ye-LS ngokusebenzisa imingxuma emibini encinci kumzimba we-valve (kancinci) ukunyusa ukuzinza komsebenzi womatshini.Ukuba i-O-ring seal kumzimba we-valve wonakaliswe, i-oyile ye-PL5 yoxinzelelo iya kunxibelelana ngokuthe ngqo netanki yamafutha, eya kubangela ngokungathanga ngqo ukuba i-valve yokukhulula ivuleke ngokuqhelekileyo, okubangela ukunyakaza okubuthathaka kunye nokucotha kwesixhobo ngasinye esisebenzayo.

Ngelizwi, ukuba i-excavator ye-PC200-6 ayikwazi ukusebenza ngokupheleleyo, ingabalelwa ubukhulu becala kumgangatho ombi we-oyile ye-oyile ye-hydraulic.Ke ngoko, buyisela into yokucoca ioyile ye-hydraulic ngexesha (efuneka ukuba itshintshwe rhoqo ngama-500) kwaye ubeke ingqalelo ekubuyiseni kwakhona.
