U lokela ho etsa eng haeba moepi oa hau a sa khone ho potoloha? Basebetsi-’moho le ’na ba kahong ba ile ba mpotsa potso ena, kahoo ha kea ka ka senya nako ho lokisa mekhoa ena ea ho rarolla mathata ’me ka akaretsa lisosa tse 10 tse latelang:
Lekola sensor ea khatello ea lisebelisoa tsa excavator, e haufi le mokokotlo oa valve ea rotary ea valve ea litsela tse ngata. E nkele sebaka ka ho toba haeba e senyehile.
Boloka moepo o le boemong bo feletseng ba rotary le boemo bo phahameng ba throttle, ebe u lekanya hore na khatello ea sefofane sa rotary e le 3.0MPa. Haeba ho se joalo, hlahloba hore na core ea pilot valve ea lisebelisoa tsa excavator e koahetse kapa e senyehile.
Sheba hore na sensor ea khatello ea rotary le valve ea rotary P/B solenoid e sebetsa hantle.
Lekola karolo e khuts'oane ea sekoaelo sa "shuttle valve core" ea anti-reversal valve le lesoba la throttle bakeng sa litšila. Sheba karolo e telele ea shuttle ea sekoaelo sa valve bakeng sa ho apara ka mokhoa o sa tloaelehang; hloekisa kapa ho fetola likarolo ha ho hlokahala.
Netefatsa hore khatello ea P2 pump high-pressure sensor e ka hare ho 10.0-15.0MPa ha excavator e le ka ho feletseng rotary stroke le nakong ea ts'ebetso.
Sheba hore na litekanyetso tsa hona joale le likhatello tsa bobeli tsa P2 ea ho laolla valve ea ho laolla le P2 valve proportional valve (lisebelisoa tsa excavator) li tloaelehile.
Hlahloba boleng ba hona joale le khatello ea bobeli ea valve ea ho tsamaea e otlolohileng. Ha throttle e phahame (ho sa tsotellehe boemo ba ho se nke lehlakore / ts'ebetso),
etsa motsamao o ikemetseng oa rotary ho netefatsa hore khatello ea bobeli ea valve e otlolohileng ea maeto e ka tlase ho 0.8MPa. Haeba ho se joalo, nkela sebaka sa "proportional valve" (excavator accessory).
Lekola konokono ea li-valve tse otlolohileng tsa maeto le konopo ea li-valve tsa rotary holim'a valve ea litsela tse ngata hore na e senyehile, 'me u hlahlobe hore na liliba tsa tsona li robehile.
Ha moepi a le mothating o feletseng oa rotary le tlas'a boemo ba ho phalla, hlahloba hore na khatello ea valve ea liphallelo ea rotary ke 3MPa.
Hlakola oli e nyane ea gear ho tsoa boema-kepeng ba ho hula oli ea mochini o fokotsang rotary 'me u hlahlobe likaroloana tsa tšepe. Lekola likarolo tse ka hare tsa enjene ea rotary (lisebelisoa tsa ho epolla) hore na li senyehile, 'me u hlahlobe libaka tse fokotsang lisebelisoa bakeng sa ho apara le li-chips tse sa tloaelehang.
