Kusiyana Pakati pa Ma Valves a Gulugufe Okhaokha, Awiri, ndi Atatu Okhazikika

Chomwe chimasiyanitsa ma valve a gulugufe ndi mitundu ina ya ma valve ndi kapangidwe kawo, makamaka kusinthasintha kwa shaft ya valavu poyerekeza ndi mpando wa valavu ndi diski. Kuchuluka kwa kusinthasintha kumakhudza momwe valavu imagwirira ntchito komanso momwe imagwirira ntchito pazinthu zosiyanasiyana zowongolera kuyenda kwa madzi. M'nkhaniyi, tifufuza kusiyana pakati pa ma valve a gulugufe amodzi, awiri, ndi atatu komanso momwe aliyense amagwiritsidwira ntchito pazinthu zinazake.

1. Valavu ya Gulugufe Yozungulira

Vavu ya gulugufe imagwira ntchito pogwiritsa ntchito diski kapena diski yomwe imazungulira kuti iyendetse kayendedwe ka zinthu kudzera mu chitoliro. Mawu oti "eccentric" amatanthauza malo a shaft ya valavu poyerekeza ndi thupi la valavu ndi mpando wake. Shaft ikachoka pampando wake, mphamvu imayikidwa pa chisindikizo pamene valavu ikutseguka ndi kutsekedwa, zomwe zimapangitsa kuti ntchito yake yotseka ikhale yabwino komanso kulola valavuyo kuthana ndi kupsinjika kwakukulu komanso kugwiritsa ntchito zinthu zovuta kwambiri.

Ma valve a gulugufe ozungulira nthawi zambiri amagawidwa m'magulu atatu:chimodzi chosiyana, kawiri kosiyanandikatatu kosiyana, iliyonse ili ndi madigiri osiyanasiyana a offset mu kapangidwe ka shaft. Tiyeni tiphunzire mozama kusiyana kwake

2. Valavu ya Gulugufe Yokha Yopanda Chidwi

Kapangidwe:Mu valavu imodzi ya gulugufe yosaoneka bwino, shaft imayikidwa pang'ono kutali ndi mpando wa valavu. Kusaoneka bwino pang'ono kumeneku kumalola diski ya valavu kuzungulira mwanjira yomwe imaletsa kuwonongeka kwambiri pa mpando wa valavu panthawi yogwira ntchito.

Magwiridwe antchito:Phindu lalikulu la kapangidwe kamodzi kosiyana ndi kamene kali mkati mwake ndilakuti kamachepetsa kukangana pakati pa diski ndi mpando potsegula ndi kutseka, kuchepetsa kusweka ndikuwonjezera nthawi ya valavu. Pamene valavu ikutsegulidwa, diski imayamba kuchoka pampando mozungulira ngati kamera, ndikupanga kupukuta komwe kumaletsa mpando wa valavu kuwonongeka.

Mapulogalamu:Ma valve a gulugufe amodzi osasunthika amagwiritsidwa ntchito m'makina omwe amafunikira mphamvu yotsika mpaka yapakati komanso komwe kutseka kwambiri sikofunikira kwambiri. Nthawi zambiri amapezeka m'mapulogalamu monga mpweya wopuma, makina oyendetsera mpweya, ndi ntchito zoyendera madzi zomwe sizimafunikira kwambiri.

Ubwino ndi Kuipa

• Kapangidwe kosavuta kokhala ndi zigawo zochepa.
• Yotsika mtengo poyerekeza ndi ma valve awiri ndi atatu ozungulira.
• Yoyenera makina opanda mphamvu zambiri pomwe kulimba kwathunthu sikofunikira kwambiri.
• Sizingapereke chisindikizo cholimba pansi pa mphamvu yamphamvu.
• Kugwira ntchito kochepa m'malo ovuta kapena osinthasintha a kayendedwe ka madzi.

3. Valavu ya Gulugufe Yachiwiri Yozungulira

Kapangidwe:Valavu ya gulugufe yooneka ngati yachilendo kawiri imakhala ndi ma offsets awiri. Offsets yoyamba ndi malo oika shaft (ofanana ndi kapangidwe kake kamodzi kokha), koma offsets yachiwiri ili mu diski yokha. Disikiyo imayikidwa pa ngodya yomwe imawonjezera kutseka ndikuchepetsa kuwonongeka kwa mpando.

Magwiridwe antchito:Kusinthasintha kwina kwa valavu ya gulugufe yooneka ngati yachilendo kawiri kumawonjezera magwiridwe antchito ake otsekereza. Pamene valavu ikutsegulidwa, m'mphepete mwa diski mumakweza kuchokera pampando pa ngodya, kuchepetsa kukangana pakati pa mpando ndi diski. Kapangidwe kameneka kamapangitsa kuti mpando wa valavu ukhale wochepa kwambiri panthawi yogwira ntchito, zomwe zimapangitsa kuti chisindikizo chikhale cholimba komanso nthawi yayitali yogwirira ntchito. Kapangidwe kameneka ndi koyenera kwambiri pakugwiritsa ntchito mphamvu yapakati komanso magwiridwe antchito apamwamba.

Mapulogalamu:Ma valve awiri a gulugufe osadziwika bwino nthawi zambiri amagwiritsidwa ntchito m'malo oyeretsera madzi, malo opopera madzi, makina a HVAC, ndi ntchito zamafuta ndi gasi, komwe kumafunika kuwongolera kayendedwe ka madzi pang'ono komanso kutseka bwino.

Ubwino ndi Kuipa

• Kutseka bwino komanso kuchepa kwa kusweka poyerekeza ndi ma valve amodzi okha.
• Kuchita bwino kwa makina opanikizika apakati.
• Kulimba kwambiri komanso kukhala ndi moyo wautali.
• Ndizovuta pang'ono komanso zodula kuposa ma valve amodzi osasinthasintha.
• Sizigwira ntchito bwino kwambiri pakugwiritsa ntchito mphamvu yamagetsi komanso kutentha kwambiri.

4. Valavu ya Gulugufe Yozungulira Katatu

Kapangidwe:Kapangidwe kapadera aka kamachepetsa kukangana kwambiri ndipo kamapereka chisindikizo chapadera poonetsetsa kuti diskiyo isakhudze mpando mpaka valavu itatsekedwa kwathunthu.

• Choyimitsa choyamba ndi malo a shaft poyerekeza ndi pakati pa diski.
• Choyimitsa chachiwiri ndi ngodya ya nkhope ya disc.
• Choyimitsa chachitatu ndi mawonekedwe a mpando wozungulira.

Magwiridwe antchito:Kapangidwe kake kamene kali ndi mawonekedwe atatu kamapangitsa kuti chitsekocho chikhale cholimba poonetsetsa kuti chimbalecho chimangolumikizana ndi mpando panthawi yomaliza yotseka. Izi zimathandiza kuti valavu ikhale yolimba kwambiri ngakhale kutentha kwambiri komanso kutentha kwambiri kusinthasintha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kwambiri komwe kutayikira sikungatheke.

Mapulogalamu:Ma valve atatu a gulugufe osakanikirana nthawi zambiri amagwiritsidwa ntchito pa ntchito zothamanga kwambiri, kutentha kwambiri, komanso kuyenda kwamphamvu. Amapezeka kwambiri m'mafakitale monga mafuta ndi gasi, kukonza mankhwala, kupanga magetsi, ndi ntchito za m'madzi, komwe kulondola, kulimba, ndi chitetezo ndizofunikira kwambiri.

Ubwino ndi Kuipa

• Kugwira ntchito bwino kwambiri potseka zitseko pansi pa kupsinjika kwakukulu komanso mikhalidwe yovuta kwambiri.
• Kusawonongeka kwambiri pampando ndi pa diski, zomwe zimapangitsa kuti munthu akhale ndi moyo wautali.
• Zodalirika pa ntchito zofunika kwambiri pomwe kutayikira sikuvomerezeka.
• Kulamulira bwino kwambiri pa ntchito zovuta zomwe zimakhala ndi kuthamanga kwakukulu kapena kupsinjika kosiyanasiyana.
• Ndi yokwera mtengo kwambiri chifukwa cha kapangidwe kake kovuta.
• Imafunika kukonza kwambiri poyerekeza ndi mitundu yosavuta ya ma valavu.
• Yolemera komanso yokulirapo, zomwe zimapangitsa kuti kukhazikitsa kukhale kovuta kwambiri pa ntchito zina.
