valavu ya cartridge yamitundu iwiri yamtundu wa hydraulic DHF08-222

Mfundozi ziyenera kuganiziridwa pogula ma hydraulic cartridge valves.

(1) Mapangidwe apakati a vavu: Chinsinsicho chimachokera kumayendedwe osankhidwa onse komanso kumverera kosagwirizana.

(2) Abrasion kukana: Pamene madzi sing'anga ndi yankho ndi mkulu ndende ya abrasive particles, deta mkati valavu ayenera kukhala zovuta.

(3) Kukana kwa dzimbiri: Chifukwa sing'angayo ndi yowononga, sankhani ndikupanga valavu yochepetsera pang'ono momwe mungathere.

(4) Kutentha ndi kupanikizika kwa sing'anga: Pamene kutentha ndi kupanikizika kwa sing'anga kuli kwakukulu ndikusintha kwambiri, ma valve omwe ali ndi kusintha pang'ono kutentha ndi kupanikizika kwa zipangizo zapakati pa valve ndi valavu yothamanga kwambiri iyenera kukhala. ntchito.

(5) Pewani kung'anima evaporation ndi cavitation: kung'anima evaporation ndi cavitation zimachitika madzi TV. Pakupanga kwenikweni, kung'anima kwa evaporation ndi cavitation kudzatulutsa kugwedezeka ndi phokoso, kuchepetsa moyo wautumiki wa valavu, kotero posankha valavu, m'pofunika kupewa kutuluka kwa evaporation ndi cavitation chifukwa cha valve.

Kusankhidwa kwa actuator ya valavu yothandizira chitetezo: Kuti valavu yowongolera igwire ntchito bwino, chowongolera chomwe chikuyenera kukhala chikuyenera kutulutsa mphamvu yokwanira kuti zitsimikizire kusindikiza kwakukulu komanso kutsegulidwa kwa valavu. Nthawi zambiri, palibe ma calibration torsion spring for pneumatic, hydraulic and electric actuators okhala ndi ntchito ziwiri. Kukula kwa mphamvu yogwira ntchito sikukhudzana ndi kayendetsedwe kake ka ntchito, kotero mfundo yofunika kwambiri posankha actuator ndikupeza mphamvu yaikulu yotulutsa mphamvu ndi torque yozungulira ya injini. Kwa makina ogwiritsira ntchito pneumatic actuator, mphamvu yochokera ikugwirizana ndi kutsegula kwa valve, ndipo mphamvu yomwe imapangidwa pa valve yolamulira idzayikanso pachiwopsezo cha machitidwe olimbitsa thupi, kotero zimayikidwa kuti pakhale mphamvu yokwanira pakutsegula konse. magulu a ma valve owongolera.

Fotokozani mitundu ya ma actuators: mphamvu yochokera kwa ma actuators ikamveka bwino, sankhani ma actuators ofanana malinga ndi zofunikira pakukonza ukadaulo wogwiritsa ntchito. Ngati pali malamulo oletsa kuphulika pamalopo, ma actuators a pneumatic ayenera kugwiritsidwa ntchito. Kuchokera pakuwona chitetezo cha chilengedwe ndi kupulumutsa mphamvu, magetsi oyendetsa magetsi ayenera kugwiritsidwa ntchito momwe angathere.
