I-bulldozer ilufumana njani ulawulo oluchanekileyo?

Ivalvu yokuqhuba eneendlela ezininzi ibalulekile.

Ulawulo oluchanekileyo lwenkqubo ye-hydraulic lubalulekile ekusebenzeni kakuhle kwe-bulldozer. Njengevalvu ephambili ekulawuleni inkqubo ye-hydraulic, ivalvu yokuqhuba eneendlela ezininzi iba yinto ephambili ekumiseleni ukusebenza kwe-bulldozer. Iyenza njani ikwazi ukuhamba ngokuguquguqukayo kweblade ye-bulldozer kwi-bulldozer enkulu?

1. Iiparameter eziSiseko zixhasa ukusebenza okuzinzileyo

Ivalvu yokuqhuba eneendlela ezininzi inika ukuguquguquka okugqwesileyo, kunye noxinzelelo lokungena olufikelela kwi-50 bar kunye noxinzelelo lwe-T-port back oluyi-3 bar, ukuqinisekisa uxinzelelo oluzinzileyo lwenkqubo ye-hydraulic phantsi kweemeko ezahlukeneyo zokusebenza. Le valve ifanelekile ekusebenziseni ioyile yeminerali enoluhlu lwe-viscosity oluyi-10-380 mm/s. Isebenza kumaqondo obushushu aphakathi kwe--20°C kunye ne-80°C, kwaye ifuna ukucoceka kweoyile ye-NAS Class 8, ukuqinisekisa ukusebenza okuthembekileyo ixesha elide. Iiparameter ezithile zidweliswe kwitheyibhile engasezantsi:

2. Uyilo lwesakhiwo lufezekisa ukuguqulwa okusebenzayo

Ivalvu yokuqhuba eneendlela ezininzi inomzimba wevalvu, umongo wevalvu, intwasahlobo, izibuko leoyile, kunye nesixhumi. Ilawula ngokuchanekileyo ukuhamba kweoyile ngokutshintsha indawo yespool. Ngexesha lokusebenza kwe-bulldozing, umqhubi utyhala isiphatho (esidityaniswe ne-logic yokusebenza kwevalvu yonyawo), esishukumisa umongo wevalvu, sivula isekethe yeoyile ehambelanayo. Ioyile ye-hydraulic iqhuba isilinda, ivumela i-bulldozer ukuba iphakamise, ithambe phambili, ithambe ngasemva, kwaye ihambe ngasekhohlo nasekunene. Umzekelo, xa ulungelelanisa umhlaba, ukulungisa kakuhle ivalvu yesilayidi kuvumela ulawulo oluchanekileyo lwe-engile yeblade. Xa uphatha izinto, ukutshintsha ngokukhawuleza isekethe yeoyile kuvumela ukulayisha nokukhulula ibhakethi ngokufanelekileyo, okwenza iintshukumo ezinzima zibe lula kwaye zilawuleke.

3. Ulawulo Oluchanekileyo Luphucula Ukusebenza Kakuhle

Isiseko sevalvu senziwe ngobuchule kwaye salungiswa ukuze silawule ngokuchanekileyo ukuhamba kweoyile ye-hydraulic. Xa usebenza kwiindawo ezixineneyo, intshukumo encinci ivumela i-bulldozer ukuba ihambe kancinci kwaye ilungise indawo yeblade. Xa ulungelelanisa iindawo ezivulekileyo, ukutyhala ngokukhawuleza kwesiphatho kuyasebenza kwaye kuvale isekethe yeoyile ngokuhamba okuphezulu, kuqinisekisa ukusebenza kakuhle kwe-bulldozer. Nokuba kukutyibilika okucolekileyo okanye ukutyibilika okukhulu, umsebenzisi unoku "khomba aze abethe," anciphise imisebenzi ephindaphindayo kwaye aphucule ukusebenza kakuhle kokwakha, aguqule abaqhubi ukusuka "kumandla angaqhelekanga" ukuya "kulawulo oluchanekileyo."

4. Ukuthembeka kunye nokuqina Qinisekisa ukusebenza rhoqo

Ngokusebenzisa izixhobo ezikumgangatho ophezulu kunye neenkqubo zokuvelisa eziphucukileyo, umzimba wevalvu unamandla okuvala kakuhle kwaye awuvuzi naphantsi koxinzelelo oluphezulu lwexesha elide kunye notshintsho oluqhelekileyo lwendlela. Izinto ezifana nezipringi kunye nee-valve cores ziyamelana nokudinwa kwaye zisebenza ngokuzinzileyo naphantsi kweemeko ezinzima zokusebenza (ezifana nothuli nodaka kwiindawo zokwakha) logama nje ioyile igcinwe icocekile. Oku kunciphisa ixesha lokungasebenzi kunye nokugcinwa ngenxa yokusilela kwevalvu, kuqinisekisa inkqubela phambili eqhubekayo yeprojekthi kunye nokunciphisa iindleko zokugcinwa kwezixhobo, kuqinisekisa ukwakhiwa "okungapheliyo". Oku kuyenza ibe "ngumqhubi othembekileyo" kwiindawo zokwakha.
