Pressure regulator Hydraulic vavu Woyendetsa valavu yopumira yolumikizira katiriji XYF10-08

Ubwino wa hydraulic system cartridge valves
     

Chifukwa valavu ya cartridge logic yakhala yokhazikika kunyumba ndi kunja, kaya ndi muyezo wapadziko lonse lapansi wa ISO, Germany DIN 24342 ndi dziko lathu (GB 2877 standard) anena za kukula kwapadziko lonse lapansi, zomwe zimatha kupanga magawo a cartridge a opanga osiyanasiyana. kukhala osinthika, ndipo sichimaphatikizapo kapangidwe ka mkati mwa valavu, zomwe zimaperekanso mapangidwe a valavu ya hydraulic ali ndi malo akuluakulu opangira chitukuko.
     

The cartridge logic valve ndi yosavuta kuphatikizira: zigawo zingapo zimatha kukhazikika mu thupi la block kuti apange hydraulic logic control system, yomwe imatha kuchepetsa kulemera kwa dongosolo lomwe limapangidwa ndi kukakamiza wamba, mayendedwe ndi ma valve otaya ndi 1/3 mpaka 1 / 4, ndipo magwiridwe antchito atha kuwonjezeka ndi 2% mpaka 4%.

Kuthamanga kwachangu: Chifukwa valavu ya cartridge ndi dongosolo la valavu yapampando, spool imayamba kutulutsa mafuta ikangochoka pampando. M'malo mwake, mawonekedwe a valve slide ayenera kumaliza kuchuluka kwake musanayambe kulumikiza dera la mafuta, ndipo nthawi yomaliza kupanikizika kwa chipinda chowongolera ndikutsegula valavu ya cartridge ndi pafupifupi 10ms, ndipo kuthamanga kwachangu kumathamanga.

Mfundo ya valavu ya solenoid yachindunji: Mukapatsidwa mphamvu, mphamvu yamagetsi yopangidwa ndi koyilo yamagetsi imakweza gawo lotsekera pampando, ndipo valavu imatsegula; Mphamvu ikatha, mphamvu yamagetsi imasowa, kasupe amakankhira mbali yotseka pampando, ndipo valavu imatsekedwa.

Gawo ndi sitepe mwachindunji kuchita solenoid valavu mfundo: ndi osakaniza akuchita mwachindunji ndi mfundo woyendetsa, pamene palibe kusiyana kuthamanga pakati polowera ndi potulukira, pambuyo mphamvu, maginito mphamvu molunjika kwa woyendetsa valavu yaing'ono ndi valavu yaikulu. kutseka mbali kukweza mmwamba motsatana, valavu amatsegula. Pamene cholowera ndi chotuluka chikafika pakusiyana koyambira, pambuyo pa mphamvu, valavu yamagetsi yamagetsi yamagetsi yamagetsi yaying'ono, valavu yayikulu yotsika m'chipinda chapansi imakwera, kuthamanga kwachipinda chapamwamba kumatsika, kuti mugwiritse ntchito kusiyana kwamphamvu kukankhira valavu yayikulu m'mwamba; Mphamvu ikazimitsidwa, valavu yoyendetsa ndege imagwiritsa ntchito mphamvu ya masika kapena kukakamiza kwapakatikati kukankhira gawo lotseka ndikusunthira pansi kutseka valavu.

Pilot solenoid valve mfundo: ikayatsidwa, mphamvu yamagetsi yamagetsi imatsegula dzenje loyendetsa, kuthamanga kwa chipinda chapamwamba kumatsika mwachangu, ndikupanga kusiyana kocheperako komanso kuthamanga kwambiri kuzungulira gawo lotseka, kuthamanga kwamadzi kumakankhira gawo lotseka kuti lipite mmwamba, valavu imatsegulidwa. ; Mphamvu ikatha, mphamvu ya masika imatseka bowo loyendetsa, ndipo kukakamiza kolowera kumapanga kusiyana kocheperako komanso kuthamanga kwambiri kuzungulira gawo lotseka la valve kudzera pabowo lodutsa mwachangu, ndipo kuthamanga kwamadzi kumakankhira gawo lotseka kuti lisunthike ndikutseka. valavu.
