I-valve ye-cartridge enezintambo ezimbili enezimo ezimbili ye-hydraulic DHF08-222

Lawa maphuzu kufanele acatshangelwe lapho uthenga ama-valve e-hydraulic cartridge.

(1) Isakhiwo se-valve core: Ukhiye usekelwe ezicini zokugeleza ezikhethiwe kanye nomuzwa ongalinganiseli.

(2) Ukumelana nemihuzuko: Uma uketshezi oluwuketshezi luyisixazululo esinezinhlayiya eziqhumayo, idatha engaphakathi kwevalvu kufanele ibe lukhuni.

(3) Ukumelana nokugqwala: Ngenxa yokuthi okuphakathi kuyagqwala, khetha futhi wakhe ivalvu elula yokukhulula kancane ngangokunokwenzeka.

(4) Izinga lokushisa kanye nokucindezela kokusebenza kwe-medium: Lapho izinga lokushisa nokucindezela kwe-medium kuphezulu futhi kushintsha kakhulu, ama-valve anezinguquko ezincane ekushiseni kanye nokucindezela kokusebenza kwezinto ezingavuthiwe ze-valve core kanye ne-valve yesango lokucindezela okuphezulu kufanele esetshenzisiwe.

(5) Gwema ukuhwamuka kwe-flash kanye ne-cavitation: ukuhwamuka kwe-flash kanye ne-cavitation kwenzeka kuphela kumidiya ye-liquid.Enkambweni yangempela yokukhiqiza, i-flash evaporation kanye ne-cavitation izokhiqiza ukudlidliza nomsindo, ukunciphisa impilo yesevisi ye-valve, ngakho-ke lapho ukhetha i-valve, kuyadingeka ukugwema ukukhuphuka kwe-flash kanye ne-cavitation ebangelwa i-valve.

Ukukhethwa kwe-actuator yevalvu yokusiza ukuphepha: Ukuze kwenziwe i-valve yokulawula isebenze ngokujwayelekile, i-actuator esebenzayo kufanele ikwazi ukukhiqiza amandla anele okukhiphayo ukuze kuqinisekiswe ukuvala okuphezulu okuhlobene nokuvulwa kwevalvu.Ngokuvamile, asikho isiphethu se-torsion sokulinganisa se-pneumatic, hydraulic kanye nama-actuator kagesi anemisebenzi emibili.Ubukhulu bamandla okusebenza abuhlobene nakancane ne-orientation yayo yokusebenza, ngakho-ke iphuzu elibalulekile ekukhetheni i-actuator ukuthola amandla amakhulu okukhipha kanye ne-torque ejikelezayo ye-motor.Ku-actuator ye-pneumatic esebenza ngokukodwa, amandla asuselwe ahlobene nokuvulwa kwe-valve, futhi amandla akhiqizwa ku-valve elawulayo azofaka engozini izici zokuzivocavoca umzimba, ngakho-ke kunqunyelwe ukudala ibhalansi yamandla kukho konke ukuvulwa. izigaba zama-valve okulawula.

Cacisa izinhlobo zama-actuator: ngemva kokuthi amandla asuselwe kuma-actuator esecacile, khetha ama-actuator ahambisanayo ngokuya ngezidingo zokucubungula izimo zohlelo lokusebenza lobuchwepheshe.Lapho kunemithetho evimbela ukuqhuma endaweni, ama-actuator womoya kufanele asetshenziswe.Ngokombono wokuvikelwa kwemvelo nokonga amandla, izixhumi zikagesi kufanele zisetshenziswe ngangokunokwenzeka.(1) Isakhiwo esiyinhloko sevalvu: Ukhiye usekelwe ezicini zokugeleza ezikhethiwe kanye nomuzwa ongalingani.
