Yadda za a tantance idan mai rage crane na Weihua / akwatin gear yana buƙatar sauyawa?

Tabbatar da ko aWeihua crane rage (akwatin gearbox) yana buƙatar madaidaicin hinges akan bambance tsakanin cikakken maye gurbin na'ura da gyaran sassa. Wannan yana dogara da farko akan nau'i uku: alamun kuskure, girman lalacewa, da ingancin gyara. Takaitattun matakai da ma'auni don tantancewa sune kamar haka:

I. Ƙimar Kai tsaye: Ba da fifiko ga Cikakkun Injin Maye gurbin a cikin yanayi masu zuwa:

Lokacin da mai rage crane ya sami lalacewar tsarin da ba za a iya jurewa ba, ko kuma farashin gyara ya kusa wuce 50% na farashin sabon na'ura, ana ba da shawarar maye gurbin injin gaba ɗaya kai tsaye:

Mummunan Lalacewar Gidaje
Gidajen simintin ƙarfe na mai rage crane yana nuna tsagewa ko karyewa, ko gidan da ke ɗauke da shi ya lalace; Ba za a iya gyara tsagewa ta hanyar walda (walda cikin sauƙi yana haifar da nakasu na biyu da gazawar hatimi).

Tsatsa mai tsanani da nakasar tushe mai hawa sama; ko da bayan matakin, ba za a iya tabbatar da coaxiality ba, yana shafar kwanciyar hankali na watsawa.

Babban Abubuwan Watsawa Mai Rarraba Lalacewa-Mataki
Gears: Manyan wurare na ƙulle-ƙulle, rami, da kwasfa a saman haƙori; kaurin hakori ya wuce 15% na ƙimar ƙira; ko karyewar hakora ko tushen tsagewar (gyaran hakori daya karye cikin sauki yana haifar da lalacewa ga wasu hakora). Tsarin Shaft: An lanƙwasa raƙuman shigarwa / fitarwa, hanyoyin da suka lalace, kuma lalacewa ta jarida ta wuce iyaka, yin gyara ba zai yiwu ba ta hanyar lantarki, walda, ko wasu matakai; zoben na ciki mai ɗauke da sako-sako da saƙon da aka saka a cikin jarida (zamewar zobe na ciki).

Laifi akai-akai da Marasa warkewa: Maimaituwar ɗigon mai: Leaks na ci gaba har bayan maye gurbin hatimin mai da gyara saman mating, wanda ya haɗa da tsufa da yawa da kuma gazawar maki.

Severely Degraded Performance: Severe vibration and abnormal noise under no-load/load conditions, temperature rise exceeding 80℃ (at an ambient temperature of 25℃), and frequent bearing burnout; ingancin watsawa ya ragu da fiye da kashi 20%, rashin cika buƙatun nauyin kaya na cranes Weihua.

Samfurin da ya ƙare ko Ƙarfafawa mara kyau: TheMai rage crane (akwatin kaya)samfurin ya tsufa; ko madaidaicin saurin mai rahusa na asali da karfin juyi ba su dace da yanayin aiki na crane ba, suna buƙatar haɓakawa da gyare-gyare.

II. Ƙimar Gyarawa: Sashe ne kawai ake buƙatar maye gurbin, Babu Cikakkiyar Mayar da Injin

Idan matsuguni na crane da tsarin shaft ba su da kyau, tare da lalacewa kawai na yanki, ana iya wargaza sassan da suka dace kuma a maye gurbinsu: Rashin Hatimi: Ciwon hatimin mai kawai da lalacewar gasket yana haifar da zubar mai, ba tare da nakasar gidaje ba. Lalacewa: Ƙarfafa lalacewa ta hanyar tsere, ƙwallon ƙwallon ƙwallon ƙafa, da fashewar keji, amma mujallar da matsuguni masu ɗaukar nauyi sun dace da al'ada, ba tare da tseren gudu ba.

Haɗe-haɗe / Elastomer lalacewa: Haɗaɗɗen haƙori saman lalacewa da fashewar elastomer; maye yana mayar da daidaiton watsawa.

Lalacewar kayan aiki na gida: ɗan guntuwar haƙori ɗaya, ba tare da shafar sauran kayan aikin ba; babu nakasar gidaje ko shaft; Ana iya maye gurbin duka biyun kayan aiki.

III. Alamomin hukumci na taimako: Ƙimar ƙima ta hanyar bayanan gwaji

Ganewar jijjiga da amo: An auna saurin girgizar mahalli mai rage crane ta amfani da mitar girgiza. A saurin ƙididdigewa, ya wuce 4.5 mm / s (National Standard GB/ T 6075.3), kuma bincike na bakan ya nuna mitar kayan aiki mara kyau, yana nuna mummunan lalacewa na abubuwan watsawa.

Amo na lokaci-lokaci "danna" tare da girgiza ya faru yayin aiki; dubawa bayan rufewa ya nuna lalacewar haƙori.

Gano Hawan Zazzabi: Bayan sa'a ɗaya na ci gaba da aiki, idan yawan zafin jiki na mahalli ya wuce 90 ℃, ko kuma bambancin zafin jiki tare da yanayin yanayi ya wuce 65 ℃, kuma an kawar da abubuwan da ba su da kyau kamar lubrication mara kyau da ƙarancin yanayin zafi na yanayi, yana nuna ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun kayan aiki ko haɗa kayan aiki.

Kwatanta Kuɗi na Gyara: Idan farashin gyaran sassa (ciki har da sassa, aiki, da lokacin raguwa) ya wuce 50% na sabon farashin injin, ya kamata a ba da fifikon maye gurbin na'urar gabaɗaya; idan ya kasance ƙasa da 50%, ana iya la'akari da gyarawa.

IV. Hukunce-hukunce Na Musamman Bisa Sharuɗɗan Ayyukan Crane: Idanmai rage cranebabban sashi ne na injin ɗagawa kuma kai tsaye yana shafar lafiyar ɗagawa, kuma akwai ɓoyayyun hatsarori kamar karyewar haƙoran gear ko lanƙwasa, ana ba da shawarar sauyawa kai tsaye, kuma ba a ba da shawarar gyara ba. Idan mai ragewa injin trolley/gantry tafiye-tafiye ne, kuma lalacewar ba ta da yawa kuma gyara na iya biyan buƙatun aiki, ana iya ba da fifikon gyara.
