Amavalufu Okugcoba - I-Auto Lubrication Reversing Valve

I-auto lubrication reversing valve i-DR4-5 series isetshenziselwa i-electric terminal type centralized lubrication system, iphampu yokugcoba idlulisa okokugcoba kumapayipi amabili amakhulu okuhlinzeka, i-valve iza nomsebenzi olawula ingcindezi futhi ingalungisa ngokuzenzakalelayo isiqondiso sengcindezi esethiwe ukusuka. 0 ~ 20Mpa, futhi kulula ukulungisa, ukwakheka kwe-auto lubrication directional valve DR4 ilula, isebenza ngokuthembekile.

I-auto lubrication directional valve DR4-5 Ukusebenza:
Umthombo wokulawula ukucindezela ophoqelelwe ibhulokhi ku-piston 1 ukwenza ipiston engu-1 ohlangothini lwesobunxele lwendlu ye-valve esiteshini segumbi se-auto lubrication directional valve DR4 (Isithombe Esibonisiwe-1), i-piston 1 kanye nepiston 2 kukhona. ngokulandelana ixhunywe nge-outlet kawoyela 1 kanye nendawo yokukhipha uwoyela 2.

Amafutha okucindezela angena emigodini emibili ye-piston 3 (Isithombe Esibonisiwe-2) esuka embotsheni yokungena kawoyela, lapho uwoyela ocindezelayo egumbini elingakwesokunxele ugeleza uphume ngembobo yokukhipha uwoyela engu-1 futhi uwoyela wokucindezela usebenza ngakwesokunxele. i-piston 3 ngokusebenzisa i-piston 1 umgodi wangaphakathi ohlangothini lwesokudla lwendlu ye-valve, bese i-piston 3 iqhubeka ngakwesokudla kwendlu ye-valve, kuyilapho uhlangothi lwesokudla lwe-piston 3 luhlangana nembobo yokubuyisela uwoyela. Uhlangothi lwesokudla lwamafutha omfutho we-cavity luvalwe nge-piston 2, lapho ukuphela kwesobunxele kwe-piston 1 (ukucindezela kwe-outlet) ukunqoba amandla entwasahlobo ku-piston, i-piston 1 kwesokunxele, kuyilapho i-piston 2 nakwesobunxele futhi.

Lapho i-piston 1 ne-piston 2 zihamba kwesokudla sendlu ye-valve (Isithombe Esibonisiwe-3), uhlangothi lwesobunxele lwe-piston 3 luxhunywe nembobo yokubuyisela uwoyela, futhi uwoyela ocindezelayo usebenza ngakwesokudla kwepiston. 3 ngomgodi ongaphakathi wepiston 2, iphushela ipiston ohlangothini lwesobunxele lwendlu yevalvu. Ngalesi sikhathi, uwoyela ocindezelayo emgodini ongakwesokudla we-piston 3 ugeleza ngaphandle kwe-oyela 2, futhi uwoyela ocindezelayo ekugcineni kwesokunxele uvalwe nge-piston 1. Lapho ingcindezi (i-outlet pressure) ekugcineni kwesokudla i-piston 2 inqoba isenzo sentwasahlobo ngokumelene ne-piston, i-piston 2 ishintshelwe kwesokudla bese i-piston 1 ishintshelwe kwesokudla. Lapho i-piston 1 kanye ne-piston 2 isuka ekugcineni kwesobunxele sendlu ye-valve, uhlangothi lwesokudla lwe-piston 3 luxhunywe nembobo yokubuyisela uwoyela, futhi uwoyela ocindezelayo usebenza ohlangothini lwesobunxele lwe-piston 3 ngokusebenzisa imbobo yangaphakathi. ipiston 1, iphushela ipiston kwesokudla kwesokudla sendlu yevalvu (Isithombe Esibonisiwe-1), ukuze kuqedelwe umjikelezo womsebenzi.

Qaphela: Uma uthola isimo sokushintshwa kwe-valve eqondisayo yokugcoba, ungafaka umthumeli wesiginali eshintshayo ku-valve, lapho uwoyela onengcindezi ephezulu udluliswa usuka "embobeni kawoyela 1" uye "embobeni kawoyela 2", ukunyakaza kwe-valve piston, abathintwayo kumthumeli wesignali bavaliwe, futhi lapho i-piston ihanjiswa ibheke emuva, abathintwayo bayanqanyulwa futhi isidlulisi singaxhunywa kusilawuli noma idivayisi yokuqapha njengoba kudingeka.
Ngaphezu kwalokho, opharetha ophethe ithubhu esobala ku-transmitter angabhekwa ngqo ekuhambeni kwenduku yenkomba.
