* Mfundo ndi ubwino wa ma valve amagetsi ndi pneumatic

Ma valve amagetsi nthawi zambiri amakhala ndi ma actuators amagetsi ndi ma valve.Valavu yamagetsi imagwiritsa ntchito mphamvu yamagetsi ngati mphamvu yoyendetsa valavu kudzera pamagetsi amagetsi kuti azindikire kutsegula ndi kutseka kwa valve.Kuti akwaniritse cholinga chosinthira mapaipi apakati.Valavu yamagetsi imakhala ndi mphamvu yayikulu yogwiritsira ntchito kuposa ma valve wamba.Kuthamanga kwa valve yamagetsi kungasinthidwe.Kapangidwe kake ndi kosavuta komanso kosavuta kukonza.Angagwiritsidwe ntchito kulamulira mpweya, madzi, nthunzi, zosiyanasiyana zikuwononga TV, matope, mafuta, madzi zitsulo ndi wailesi radioactive, etc. The otaya mitundu yosiyanasiyana ya madzimadzi.

Ma valve a pneumatic ndi ma valve oyendetsedwa ndi mpweya woponderezedwa.Mpweya woponderezedwa umagwiritsidwa ntchito kukankhira ma pistoni angapo ophatikizika a pneumatic mu actuator kuti asunthe, ndipo mphamvuyo imaperekedwa ku crossbeam ndi mawonekedwe a njanji yamkati yopindika, yomwe imayendetsa nsonga yozungulira kuti izungulire.The compressed air disk imatumizidwa ku silinda iliyonse, ndipo malo olowera mpweya ndi malo otulutsira amasinthidwa kuti asinthe kuzungulira kwa spindle.Mayendedwe, malinga ndi zofunikira za torque (valavu) yozungulira, kuchuluka kwa kuphatikiza kwa silinda kumatha kusinthidwa kuyendetsa katundu (vavu) kuti agwire ntchito.Ma valve pneumatic angagwiritsidwe ntchito kuwongolera kutuluka kwamitundu yosiyanasiyana yamadzimadzi monga mpweya, madzi, nthunzi, zowononga zosiyanasiyana, matope, mafuta, zitsulo zamadzimadzi ndi ma radio radio.

Ubwino wa mavavu amagetsi ndi pneumatic:

1. Vavu ya pneumatic imakhala ndi zotsatira zabwino pamadzi apakati ndi ang'onoang'ono a chitoliro, otsika mtengo komanso kukonza bwino.Zoipa: Zimakhudzidwa ndi kusinthasintha kwa mpweya, zimakhala zosavuta kukhudzidwa ndi madzi mu mpweya wa mpweya kumpoto kwa nyengo yozizira, zomwe zimapangitsa kuti gawo lopatsirana likhale lozizira komanso losasuntha.Nthawi zambiri, pneumatic imathamanga kwambiri kuposa magetsi, ndipo magetsi amakhala amitundu iwiri.Mtengo wa pneumatic ndi wokwera kwambiri.

2 Vavu yamagetsi imakhala ndi zotsatira zabwino pamadzi apakati ndi mpweya waukulu wa chitoliro, ndipo sichikhudzidwa ndi nyengo.Osakhudzidwa ndi kuthamanga kwa mpweya.Zoipa: kukwera mtengo, osati kwabwino m'malo achinyezi.

3. Kuchita pang'onopang'ono kwa ma valve amagetsi.Palibe mitundu yambiri ya ma valve amagetsi omwe amatha kukwaniritsa kuphulika.Mavavu a chibayo amayenda mwachangu, ndipo zotsimikizira kuphulika ndizotsika mtengo kuposa zamagetsi.

4. Ma valve amagetsi amagwiritsidwa ntchito m'malo ena okhala ndi mapaipi akuluakulu, chifukwa ndizovuta kuchita pneumatically, koma kukhazikika kwa ma valve amagetsi sikuli bwino ngati kusintha kwa pneumatic.The actuator adzakhala ndi kupanikizana dzino kwa nthawi yaitali.Mavavu a pneumatic ali ndi liwiro lalikulu losinthira komanso kulondola kwambiri koma ayenera kukhala okhazikika.Gwero la gasi.
