Chifukwa Chake Ma Winches a Hydraulic Amapambana Ma Winches Amagetsi mu Ntchito Zopitilira za Migodi Yolemera

Kusiyana Kofunikira Pakupanga Magalimoto - Chomwe Chimapangitsa Ma Winches a Hydraulic Kumangidwa Kuti Agwiritsidwe Ntchito Molakwika

Ndakhala zaka khumi ndi zisanu ku Yining Hydraulic ndikupanga makina opangira ma winchi ogwiritsira ntchito migodi, zapamadzi, komanso zomangamanga, ndipo kusiyana kwa nzeru za uinjiniya pakati pa ma winchi a hydraulic ndi amagetsi n'koonekeratu:Ma mota a hydraulic amapangidwa mopitirira muyeso kuti apulumuke mopitirira muyeso, pomwe ma mota amagetsi ndi zida zolondola zomwe zimadziteteza pozimitsa.Kusiyana kumeneku si vuto la kapangidwe ka ukadaulo uliwonse — ndi zotsatira za fizikiki yomwe ili pansi pake. Ma hydraulic motors amagwiritsa ntchito madzi opanikizika (nthawi zambiri amakhala 250-350 bar mu ntchito za winch za migodi) kuti ayendetse gulu lozungulira la ma pistoni kapena magiya. Madziwo okha amagwira ntchito ngati njira yotumizira mphamvu komanso njira yoziziritsira — pamene madziwo akuyenda kudzera mu injini, amanyamula kutentha kupita ku choziziritsira mafuta cha makinawo. Ngati injiniyo yadzaza kwambiri, valavu yochepetsera kupanikizika kwa makinawo imatsegulidwa pa kupsinjika komwe kwayikidwa (nthawi zambiri 315-350 bar) ndikusuntha kuyenda, kuteteza zigawo za makinawo ku kuwonongeka kochulukira popanda kutseka makinawo.

Mosiyana ndi zimenezi, ma mota amagetsi amasintha magetsi kukhala maginito kuti apange mphamvu. Ma winding a mota — waya wamkuwa wotetezedwa ndi Class F (madigiri Celsius 155) kapena Class H (madigiri Celsius 180) — amapanga kutentha kofanana ndi sikweya ya magetsi (kutayika kwa I-squared-R).Mu ntchito yofufuza mopitilira pomwe winch imakoka katundu kwa mphindi 30-60, ma winding a mota amafika pakutentha mkati mwa mphindi 15-25 ndipo chotetezera kutentha kapena VFD imayendetsa mota kuti isawonongeke ndi kutenthetsa.Izi si vuto — ndi injini yomwe imadziteteza ku kuwonongeka kosatha — koma kwa manejala wopanga mgodi akuyang'ana winch ikusiya kugwira ntchito, kusiyana kwake ndi kwamaphunziro.ISO 5001Miyezo yogwiritsira ntchito bwino injini yamagetsi, ma mota oyendetsedwa mosalekeza amafunikira kuziziritsa mpweya mokakamizidwa (ma mota a TEFC okhala ndi mafani akunja) kapena kuziziritsa jaketi la madzi kuti agwire ntchito kupitirira 40% ya ntchito - ndipo ngakhale kuziziritsa mokakamizidwa, malire a kutentha nthawi zambiri amakhala 60-70% ya ntchito mu kutentha kwa madigiri 35-45 Celsius komwe kumachitika m'migodi yotseguka ya ku Australia ndi South America.

Kuyerekeza kwa Ntchito: Chifukwa Chake Malire a Kutentha kwa Winch Yamagetsi Akukhala Vuto Lopanga Migodi

Mafotokozedwe a kayendedwe ka ntchito pa pepala la data la winch yamagetsi akuyimira mikhalidwe ya labotale — madigiri 25 Celsius ozungulira, mpweya woyera, magetsi ovoteledwa — zomwe sizigwira ntchito ku malo ogwirira ntchito m'migodi yolimba.Mu migodi yeniyeni pamalo otentha madigiri 40 Celsius pomwe fumbi louluka limatseka pang'ono zipsepse zoziziritsira injini, ntchito yeniyeni ya winch yamagetsi ya "40%" imatsika kufika pafupifupi 25-30%. Pa mgodi womwe umagwira ntchito maola 10, zikutanthauza kuti winch yamagetsi imatha kugwira ntchito kwa maola 2.5-3 okha pa nthawi iliyonse kutentha kusanayambe kukwera - ndipo nthawi yozizira (nthawi zambiri mphindi 30-45 kuti ibwerere ku kutentha kotetezeka) imachepetsa mwachindunji mphamvu yopangira.

At Yining Hydraulic, ma winchi athu a IYJ a hydraulic apangidwa kuti azigwira ntchito mosalekeza 100%, ndipo choziziritsira mafuta cha hydraulic power unit chimakhala ndi kutentha kwakukulu komwe kumayembekezeredwa komanso chitetezo cha 15%.Choziziritsira mafuta ndi gawo loyang'anira kutentha lomwe limapangitsa kuti ntchito yonse ikhale yotheka 100%.— imasamutsa kutentha kuchokera ku madzi a hydraulic kupita ku mpweya wozungulira (kapena madzi ozizira, kuti agwiritsidwe ntchito mumigodi ya pansi pa nthaka), kusunga kutentha kwa madzi pansi pa madigiri 65 Celsius ngakhale ikagwiritsidwa ntchito mosalekeza. Mota yamagetsi yoyendetsa pampu ya hydraulic ndiyo gawo lokhalo lamagetsi mu dongosololi, ndipo imayenda pa liwiro losasintha komanso katundu mosasamala kanthu za katundu wa winch — kuchotsa kusintha kwa kutentha komwe kumapha ma winch motors amagetsi.

Kugwirizana kwa Mphamvu Pansi pa Mtolo Wosinthasintha: Ubwino wa Hydraulic mu Kuyamba Kofewa ndi Kutenga Modzidzimutsa

Mu ntchito za migodi, pafupifupi 67% ya zokoka zonse zimaphatikizapo kuyamba ndi katundu wosasinthika - skip yodzaza ndi miyala, galimoto yonyamula katundu yoyima, ndi lamba wonyamula katundu womangika.Kuyamba ndi mphamvu yosasunthika kumafuna mphamvu yochulukirapo pa zero RPM, ndipo apa ndi pomwe ubwino waukulu wa injini ya hydraulic umaonekera kwambiri. Mota ya hydraulic imapanga mphamvu yake yayikulu panthawi yomwe valavu yowongolera yolunjika imatsegulidwa - kuthamanga kumawonjezeka nthawi yomweyo (mkati mwa mamilimita 50-100) mu hydraulic circuit, ndipo mota imapereka mphamvu yonse ya stall pa zero RPM. Palibe mphamvu yolowera, palibe kukwera kwa kutentha kozungulira, komanso palibe kuyika kwa contactor koyambira.

Mota yamagetsi yoyambira motsutsana ndi katundu wosasinthasintha imakoka mphamvu yamagetsi yozungulira yotsekedwa (nthawi zambiri nthawi 6-8 mphamvu yamagetsi yodzaza) nthawi yonse yoyambira — nthawi zambiri masekondi 2-5 kuti iyambe mwachindunji pa intaneti, kapena masekondi 5-15 kuti iyambe yofewa yokweza mphamvu yamagetsi.Chozungulira chilichonse chotsekedwa chimayamba kutentha kwambiri kuti ma windings a mota azikhala ndi maola ogwirira ntchito ofanana ndi 0.5-1.0 chifukwa kutentha kwa I-squared-R panthawi yamagetsi olowa kumakhala kokwera nthawi 36-64 kuposa nthawi yanthawi zonse.Mu kusintha kwa migodi komwe kumakhala ndi magawo oyambira 20-30, kukalamba kwa kutentha komwe kumachitika chifukwa choyambira kokha kumatha kutenga maola ofanana 10-30 a moyo wozungulira mu kusintha kamodzi kwa maola 10.
