Kungani isilawuli sokuhamba somshini wokumba sizinzile futhi siphephileLe valve yezinyawo ze-hydraulic inikeza impendulo

Ngesikhathi sokusebenza kwe-excavator, ukuzinza, ukuphepha, kanye nokusebenza kahle kokulawula ukuhamba kuthinta ngqo ukusebenza kokwakhiwa. Njengevalvu ye-hydraulic eyinhloko elawula imisebenzi yokuhamba, ivalvu ye-hydraulic foot foot ye-excavator travel ibalulekile ekuqinisekiseni ukusebenza kokuhamba kwe-excavator. Nansi i-lowdown.

1. Amapharamitha Ayisisekelo Nokuzivumelanisa Nezimo

I-valve ye-hydraulic foot foot ye-excavator travel inengcindezi ephezulu yokungena engu-6.9 MPa, ehlangabezana nezidingo zengcindezi zezimo zokusebenza eziyinkimbinkimbi. Ingcindezi yayo ephezulu yangemuva ingu-0.3 MPa, okunciphisa ngempumelelo ukulahleka kwamandla. Isebenza ngokuzinzile ngaphakathi kwebanga lokushisa elibanzi likawoyela, kusukela ku--20°C kuya ku-90°C, okwenza ifaneleke ezindaweni zokusebenza ezahlukahlukene. Ngaphezu kwalokho, isidingo sokuhlanzeka kukawoyela siyizinga le-NAS 9 noma ngaphansi ukuqinisekisa ukusebenza kwesikhathi eside nokwethembekile komzimba we-valve. Amapharamitha aboniswe kuthebula elilandelayo:

2. Izinzuzo Zokusebenza Nokulawula

Ngokuphathelene nokusebenza, kufeza ukuguqulwa okuphumelelayo kwamandla omuntu abe amandla omshini. Abaqhubi bangakwazi ukulungisa kalula ukunyakaza komshini wokumba phambili nokubuyela emuva ngokucindezela okulula kwe-pedal, okwenza inqubo yokusebenza ibe lula futhi kuncishiswe ama-curve okufunda, okwenza kube lula ngisho nakubaqhubi abasafufusa ukuba baluqonde ngokushesha lolu hlelo.

Ngokuphathelene nokunemba kokulawula, i-valve yezinyawo eklanywe ngokucophelela futhi elinganisiwe inikeza ukulawula ukugeleza nokucindezela okunembile nokuzinzile. Kungakhathaliseki ukuthi yenza ukulungiswa okuhle ezindaweni ezivalekile noma ishintsha ngokushesha ezindaweni ezivulekile, isabela ngokunembile, iqinisekisa ukunyakaza kwe-excavator okuzinzile nokulawulekayo futhi ithuthukisa ukunemba kokwakhiwa.

3. Ukuthembeka Nokuphepha

Ngokuphathelene nokuthembeka, i-hydraulic foot valve isebenzisa izingxenye ezisezingeni eliphezulu kanye nobuchwepheshe bokukhiqiza, iqinisekisa ukuvalwa okuhle kakhulu nokuqina. Imelana nemithwalo esindayo isikhathi eside ngaphandle kokuvuza noma ukulimaza, inciphisa isikhathi sokungasebenzi, iqinisekisa ukusebenza okuqhubekayo, futhi inciphisa izindleko zokulungisa imishini.

Ngokuphathelene nokuphepha, i-valve yonyawo ifakwe inkinobho yokuphepha noma indlela yokukhiya. Lokhu kuvimbela ukunyathela ngengozi ngesikhathi sokuphumula kokwakha noma lapho umshini wokumba ungasebenzi, okuhlinzeka ngesithiyo sokuphepha esiqinile kubasebenzi kanye nokuvimbela umonakalo womuntu siqu noma wempahla ngenxa yokunyakaza kwemishini okungalindelekile.

Kusukela ekuzivumelaniseni nokusebenza okuyisisekelo kuya ezinzuzweni eziningi zokusebenza, ukulawula, ukuthembeka, kanye nokuphepha, ivalvu yezinyawo ze-hydraulic yokuhamba nge-excavator, ngamandla ayo aqinile, iqinisekisa ukulawulwa kokuhamba nge-excavator okuzinzile, okuphephile, nokuphumelelayo. Sekuyisici esibalulekile esibalulekile ekusebenzeni kwe-excavator, okufaka isandla ekwakhiweni okubushelelezi nokuphephile.
