Indlela ejayelekileko yokusingatha amaphutha wevalvu ye-pneumatic

1 Indlela yokwelapha ukwandisa ukuvuza kwevalvu ye-pneumatic

Nangabe icala le-valve spool ligugile ukwehlisa ukuvuza kwe-valve, kuyatlhogeka bona kuhlanzwe begodu kususwe umzimba wangaphandle; nangabe umehluko wokugandeleleka mkhulu, i-actuator yevalvu ye-pneumatic ithuthukiswa ukwandisa umthombo wegesi nokwehlisa ukuvuza. Ukungezelela, lokha nakufakwa ivalvu yomoya, ubude besiqu esikhethiweko kufanele bube buphakathi ukukhandela ukuvuza okubangelwa kukuthi ivalvu ingavali ngokupheleleko.

2 Indlela yevalvu yomoya

Ukungazinzi kwevalvu yomoya okubangelwa mfutho wesiginali ongazinzileko, ukusebenza okuzinzileko kwehlelo lenethiwekhi yamandla kufanele kuqinisekiswe; isisetjenziswa sokubeka kufanele silungiswe, begodu isibeki esitjha singathathelwa indawo lokha nakutlhogekako ukuqinisekisa ukuzinza komfutho womthombo womoya. Ungaphinde ufake isiqu sevalvu nofana ufake ukuthambisa ukwehlisa ukutjhayisana kwengcenye yokuthintana kwesiqu sevalvu, ukwehlisa ukungazinzi kwevalvu yomoya, kodwana ungalungisa ukunemba kwephayiphu yesisetjenziswa sokubeka, ukwenzela bona kuqedwe iphutha elingazinzileko levalvu yomoya.

3 indlela yokwelapha iphutha lokudlidliza kwevalvu ye-pneumatic

Ukudlidliza kwevalvu yomoya okubangelwa kutjhayisana hlangana kwebhatjhi nomgogodla wevalvu, ibhotjhi idinga ukutjhugululwa msinyana; ukudlidliza kwevalvu yomoya ezungeze ivalvu yomoya, susa ukudlidliza bese ubuyisela ukudlidliza kwesisekelo sevalvu yomoya; hlaziya begodu wahlulele ukudlidliza okubangelwa yindlela yamanje yokugeleza kwevalvu yesihlalo esisodwa, begodu ulungise indlela efaneleko yokufaka yevalvu yomoya.

4 Indlela yokuphatha amaphutha abuthakathaka isenzo sevalvu ye-pneumatic

Ukusebenza kabuthaka kwevalvu ye-pneumatic kuhlobana khulu nokulimala kwe-diaphragm, njeke idayaphragm etja kufanele ifakwe esikhundleni sayo ngesikhathi; hlola ngokutjheja bona amafutha wokuthambisa we-graphite ne-asbestos kanye nokugcwaliswa kwe-PTFE kujayelekile na, begodu uyifake esikhundleni sayo nangabe kuyatlhogeka ukuqinisekisa bona bazokususa umzimba wangaphandle emzimbeni wevalvu ngesikhathi ukuqinisekisa ukuhlanzeka komzimba wevalvu; phatha isiqu sevalvu, yehlisa ukutjhayisana hlangana nesiqu sevalvu kanye neengcenye ezizungezeko, ukwenzela bona kurarululwe ukubhalelwa kabuthaka kwesenzo sevalvu ye-pneumatic.

5 ivalvu yomoya

Ngomthombo wegesi kodwana ivalvu yomoya ayisebenzi, kuyatlhogeka bona uhlole umugqa wemiyalo ngamunye ngamunye ukuqeda iphutha ngesikhathi. Lokha i-position-er ku-valve ye-pneumatic ingenawo umfakela nokutjengisa, kuyatlhogeka bona kufakwe esikhundleni se-locator etja ngesikhathi; malungana nokuguquguquka okukhulu komgogodla wevalvu nesiqu, kufanele ithathelwe indawo ngesikhathi ukuqinisekisa ubujamo obufaneleko besondo lesandla.
