Buku Lotsogolera la Silinda ya Hydraulic: Ntchito, Kukula kwa Bore ndi Zipangizo

Ntchito Zazikulu ndi Mfundo Zogwirira Ntchito za Ma Silinda a Hydraulic mu Machitidwe Amakono

Momwe Ma Silinda a Hydraulic Amagwirira Ntchito

Silinda ya hydraulic ndi choyatsira magetsi mu machitidwe a hydraulic. Chimasintha mphamvu ya hydraulic kukhala mphamvu yamakina kuti iyende molunjika. Mfundo yogwirira ntchito imatsatira lamulo la Pascal. Kupanikizika kwa mafuta a hydraulic kumakankhira pisitoni mkati mwa chubu cha silinda.

Njira Yogwirira Ntchito:

1. Mafuta Olowera: Pampu ya hydraulic imatumiza mafuta mu chubu cha silinda
2. Kuyenda kwa Pistoni: Pakukakamizidwa, pisitoni imakankhira katunduyo molunjika
3. Kubwerera kwa Stroke: Akafika pamalo ake, mafuta amabwerera kuti amalize kuzungulira

Kapangidwe kosavuta aka kamapereka mphamvu yamphamvu yotulutsa. Silinda ya hydraulic imatha kunyamula katundu wolemera motsatira njira yolondola.

Madera Akuluakulu Ogwiritsira Ntchito:

Masilinda a hydraulic amagwira ntchito m'mafakitale ambiri. Amapereka mphamvu yayikulu yokankhira makina omwe amafunika kuyenda molunjika. Magawo ofunikira ndi awa:

• Makina osindikizira a hydraulic opangira zitsulo
• Makina omangira monga zokumba
• Zipangizo zachitsulo
• Makina opangira jakisoni
• Machitidwe opanga zinthu

Mtundu uliwonse wa silinda ya hydraulic umapereka mphamvu zosiyanasiyana. Mainjiniya amasankha kutengera zomwe zimafunika pa katundu ndi kapangidwe ka makina.

Kusiyana kwa Bore Diameter ndi Zotsatira Zake pa Kugwira Ntchito kwa Mphamvu Yotulutsa Silinda

Ubale Pakati pa Bore ndi Mphamvu

Kukula kwa chibowo kumatsimikiza mphamvu yotulutsa ya silinda ya hydraulic. Chibowo chachikulu chimapanga mphamvu yochulukirapo. Fomula yake ndi yosavuta:

Kumene:

• F= Mphamvu ya chiphunzitso (Newtons)
• D= Chidutswa cha m'mimba mwake (mm)
• P= Kupanikizika kwa dongosolo (MPa)

Magulu a Kukula kwa Bore:

Mabowo osiyanasiyana amagwira ntchito zosiyanasiyana:

Mzere wa Piston Rod Ndi Wofunika Kwambiri

M'mimba mwake wa ndodo ya pistoni nthawi zambiri umakhala 30% mpaka 70% ya kukula kwa bore. Ndodo yokhuthala imakana kupindika bwino. Izi ndizofunikira kwambiri pa strokes zazitali kapena katundu wonyamula mbali. Pa strokes zopitirira mamita 1.5, kapangidwe kotsutsana ndi kupindika kamakhala kofunikira. Popanda kapangidwe koyenera, ndodoyo imatha kupindika ikanyamula katundu.

Mukasankha silinda ya hydraulic, ganizirani kukula kwa bore ndi ndodo. Kuphatikiza koyenera kumatsimikizira kuti ikugwira ntchito bwino komanso kuti igwire ntchito nthawi yayitali.

Buku Lotsogolera Kusankha Zinthu Za Machubu a Silinda, Ndodo za Piston, ndi Zigawo Zofunika

Zipangizo za Silinda

Chubu cha silinda chimasunga mafuta a hydraulic ndipo chimatsogolera pisitoni. Kusankha zinthu kumadalira mphamvu ndi malo:

Pa ntchito zambiri za silinda ya hydraulic, chitsulo chopanda msoko #45 chimapereka mtengo wabwino kwambiri. Chimagwira ntchito ndi kuthamanga kwamphamvu ndipo chimateteza kuwonongeka.

Zipangizo za Ndodo ya Pisitoni

Ndodo ya pisitoni imalumikizana ndi katundu. Iyenera kukana kupindika ndi kuwonongeka:

Kuphimba kwa Chrome ndi kofala kwambiri pa ndodo zambiri za pistoni. Malo olimba a chrome amalimbana ndi kuwonongeka ndi dzimbiri. Pazikhalidwe zovuta, chitsulo cha alloy cha 40Cr chimapereka kukana kuwonongeka ndi 30%.

Zigawo Zina Zofunikira

• Pisitoni: Yopangidwa ndi chitsulo chosatha kusweka, chitsulo chotuwa (HT300/350), chitsulo, kapena aluminiyamu. Kulumikizana ndi ndodo kuyenera kukhala mkati mwa 0.03mm
• Chipewa cha SilindaMitundu ya kupanikizika kochepa imagwiritsa ntchito zinthu zoyeretsera. Mitundu ya kupanikizika kwapakati imagwiritsa ntchito chitsulo cha imvi cha HT300. Mitundu ya kupanikizika kwakukulu imagwiritsa ntchito chitsulo #35 kapena #45. Malo otsogolera nthawi zambiri amakhala ndi zigawo zovekedwa ndi bronze alloy.
• Zisindikizo: Rabala ya nitrile (yosagwira mafuta), polyurethane (yosagwira ntchito), kapena rabala ya fluoro (yotentha kwambiri). Sankhani kutengera mtundu wa mafuta a hydraulic ndi kutentha komwe kumagwiritsidwa ntchito.

Malangizo Othandiza Osankha

1. Ikani Kupanikizika Choyamba, Kenako Werengani KuboolaYambani ndi zofunikira pa katundu wanu. Werengani mphamvu yomwe mukufuna. Kenako sankhani kukula kwa bore yotsika mtengo kwambiri.
2. Onjezani Malire OtetezekaKupanikizika kwa kapangidwe kake kuyenera kukhala 20% mpaka 30% kuposa kuthamanga kwakukulu kwa dongosolo
3. Malo Ogwirizana: Pa malo akunja kapena owononga, sankhani chitsulo chosapanga dzimbiri chokhala ndi zokutira zoteteza. Pa kutentha kwambiri, gwiritsani ntchito zisindikizo za rabara za fluoro
4. Ganizirani za Kalembedwe Koyikira: Kuyika kwa Flange, eye, kapena clevis kumakhudza kapangidwe ka silinda ya hydraulic. Tsimikizirani mtundu woyika msanga kuti mupewe kusintha mtsogolo

Mapeto Omaliza

Ma silinda a hydraulic amagwira ntchito ngati ma actuator ofunikira kwambiri m'makampani amakono. Amasintha mphamvu yamadzimadzi kukhala kuyenda kodalirika. Kukula kwa bore kumakhudza mwachindunji mphamvu yotulutsa, ndipo mabowo akuluakulu amapanga mphamvu zambiri zokankhira. Kusankha zinthu kumatsimikiza kulimba kwa silinda ndi magwiridwe antchito. Machubu a silinda nthawi zambiri amagwiritsa ntchito chitsulo chosasunthika #45 pakugwiritsa ntchito mphamvu yamagetsi. Ndodo za piston zimafunika kukonza pamwamba monga chrome plating kuti zisawonongeke. Mainjiniya ayenera kulinganiza zofunikira za mphamvu, momwe chilengedwe chilili, komanso mtengo wake posankha silinda ya hydraulic. Pomvetsetsa zotsatira za bore ndi katundu wa zinthu, ogwiritsa ntchito amatha kusankha silinda yoyenera pa ntchito iliyonse. Izi zimatsimikizira kukhala ndi nthawi yayitali yogwira ntchito komanso magwiridwe antchito abwino kwambiri pama hydraulic press, zida zomangira, ndi makina opangira.
