Zinthu ziwiri zodziwika zomwe zimakhudza moyo wautumiki wa ma valve a pneumatic diaphragm.

1. Njira yogwirira ntchito ndi kutsegula kwakukulu kuti iwonjezere moyo wautumiki imalola kuti valve yolamulira pneumatic igwire ntchito yotsegula kwambiri momwe zingathere, monga 90%. Mwa njira iyi, zowonongeka monga cavitation ndi kukokoloka zimachitika pamutu wa valavu pachimake. Pamene spool ikuwonongedwa ndipo kutuluka kumawonjezeka, valve yogwirizana imatsekedwa kachiwiri. Izi zidzapitirizabe kuwononga ndi kutseka pang'onopang'ono, kotero kuti spool yonse ikugwiritsidwa ntchito mokwanira mpaka muzu ndi kusindikiza pamwamba pa spool zowonongeka ndipo sizingagwiritsidwe ntchito. Pa nthawi yomweyo, lalikulu-kutsegula ntchito throttle kusiyana ndi lalikulu ndi kukokoloka ndi wofooka. Izi zikhoza kuonjezera moyo wa valavu nthawi zambiri kuposa 1 mpaka 5 poyerekeza ndi ntchito yoyamba ya valve pakatikati ndi zotsegula zazing'ono. Mofananamo, ngati chomera chamankhwala chimagwiritsa ntchito njirayi, moyo wautumiki wa valve ya pneumatic diaphragm ukuwonjezeka ndi 2 nthawi.
2.Decrease S kuonjezera kutsegula ntchito ndi kuonjezera moyo. Njira yochepetsera S, ndiko kuti, kuonjezera kutayika kwa dongosolo kupatulapo valavu yoyendetsera mpweya, kotero kuti kutsika kwapakati komwe kumagawidwa ku valve kumachepetsedwa, pofuna kuonetsetsa kuti kutuluka kumadutsa mu valve yolamulira pneumatic, kusintha kwa pneumatic kuyenera kuwonjezeka Panthawi imodzimodziyo, digiri yotsegulira valve imachepetsa kutsika kwa valve, komwe kumachepetsa cavitation ndi kukokoloka. Njira zenizeni ndi izi: kutsekemera kwa orifice kumayikidwa kuseri kwa valavu kuti iwononge kutsika ndikutseka valavu yamanja yolumikizidwa mumndandanda wapaipi mpaka valavu yowongolera pneumatic ipeza mwayi wogwirira ntchito. Ndizosavuta, zosavuta komanso zothandiza kutengera njira iyi ya ma valve a pneumatic diaphragm mofanana ndi pamene valve imasankhidwa kuti igwire ntchito potsegula pang'ono pachiyambi.
