Maemo a ts'ebeliso le melemo ea tekheniki ea li-valve tsa sefofane sa bulldozer
Ntlafatso ea taolo ea mosebetsi oa sekolo o etsetsoang hae: Belofo ea sefofane e laola clutch ka bo eona ka electro-hydraulic control, e kopantsoeng le ts'ebetso ea ho notlela ea hydraulic torque converter, e lumellang bulldozer ho tloha ho phetiso ea mochini oa haeteroliki ka lebelo le tlase ho ea ho mochini ka lebelo le phahameng, ho fokotsa tšebeliso ea mafura ka ho feta 10%. Mohlala, bulldozer ea SD52-5 e tsoang Shantui e na le tlhahiso e kholo ea lipalangoang tsa mobu ea 1313m ³/h bohole ba 40m, mme ts'ebetso ea eona e nepahetseng e its'etleha taolong e nepahetseng ea sisteme ea haeteroliki ka valve ea sefofane.

Tšireletseho le boiketlo bo ntlafetseng: Li-bulldozer tse ling (tse kang SD52-5) li na le litulo tsa KAB tse ka potolohang 15℃, hammoho le valve ea sefofane ho lekola boemo ba mobu o lokollang mobu, ho ntlafatsa ponahalo ea ts'ebetso le polokeho. Ntle le moo, ho kopanngoa ha modular ha valve ea sefofane e nang le phetisetso e bohareng le clutch ea ho tsamaisa e ka fihlela ts'ebetso ea brake ea ho paka le ho thibela ho putlama ha maralla.
Ikamahanya le maemo a mangata a sebetsang: Lebelo la khatello ea taolo ea valve ea sefofane e hloka ho fetoloa ho latela litlhoko tsa ts'ebetso. Mohlala, valve ea sefofane ea DJS e na le khatello ea taolo ea 0.5-2.5MPa bakeng sa khokahano ea bakete ea rotary le 0.5-2.0MPa bakeng sa khokahano ea boom, e ka ikamahanyang le sistimi ea hydraulic ea li-loaders tse kholo le tse mahareng le libulldozer joalo ka ZL0.50 le ZL. Pilot valve ke valve e nyane ea hydraulic control valve e sebelisetsoang ho laola ketso ea valve ea mantlha ea hydraulic, e leng ea "command element" lits'ebetsong tsa hydraulic. E fetola oli e nang le khatello e tlase hore e be lipontšo tsa haeteroliki ka ho amohela matšoao a ts'ebetso ea mochini ho tsoa ho basebelisi (joalo ka ts'ebetso ea li-levers le pedals), e tsamaisa motsamao oa mantlha oa li-valve, ka hona e laola liketso tsa lisebelisoa tse sebetsang tsa bulldozer (joalo ka likharafu le li-looseners tsa mobu) le lits'ebetso tsa ho tsamaea.

Kakaretso ea melemo ea kopo, matšeliso a mokhanni: e fokotsa haholo mokhathala oa ts'ebetso, haholo-holo nakong ea mosebetsi o tsoelang pele oa nako e telele.
Ho nepahala ha mosebetsi oa sekolo o etsetsoang hae: Finyella taolo ea boemo ba lehare la limilimithara le tokiso ea lebelo le boreleli, ho ntlafatsa boleng ba mosebetsi oa sekolo o kang oa ho bata le ho laola moepa.
Ho sebetsa hantle ha mosebetsi oa sekolo o etsetsoang hae, karabelo e potlakileng, le taolo e nepahetseng li fokolitse ts'ebetso e pheta-phetoang le ho ntlafatsa mosebetsi o sebetsang ka nako ea yuniti.
Tšireletso ea mochini le taolo e boreleli li fokotsa ts'oaetso ea hydraulic, li lelefatsa nako ea bophelo ea likarolo tsa hydraulic le likarolo tsa sebopeho.
*Katoloso ya tshebetso: E fana ka polatefomo ya motheo bakeng sa ho kopanya ditaolo tse tswetseng pele tsa elektroniki tse jwalo ka diseseteme tsa othomathike le remote control, haholoholo bakeng sa electro{0}}hydraulic proportional pilot valves.

Bohlokoa
Ho ka boleloa hore ntle le tsamaiso ea liteko, ts'ebetso, boiketlo, le ts'ebetso ea li-bulldozer tsa morao-rao (haholo-holo tse mahareng ho isa ho tse kholo le tse phahameng{0}}mefuta ea qetello) li tla fokotseha haholo. Valve ea sefofane ke karolo ea mantlha ea mochini oa taolo ea sefofane, e sebetsang e le borokho lipakeng tsa sepheo sa mokhanni le mochini o matla oa hydraulic actuator. Ts'ebetso ea eona le ts'epahalo ea eona li supa ka kotloloho boiphihlelo ba ho sebetsana le bokhoni ba ts'ebetso ea bulldozer eohle.
