Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following Londonfl jerseys supplyn Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of swomen nfl jerseystaying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yecheap nfl jerseys wholesales," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

      MZD1交流單相制動(dòng)電磁鐵,是上海人民電氣有限公司 http://www.hqbet5695.com 為您提供的關(guān)于MZD1交流單相制動(dòng)電磁鐵型號,MZD1交流單相制動(dòng)電磁鐵價(jià)格,有關(guān)MZD1交流單相制...

    產(chǎn)品介紹

    MZD1系列交流單相制動(dòng)電磁鐵(以下簡稱電磁鐵)適用于交流50Hz額定電壓至380V的電路中。主要作為匹配TJ2系列或JWZ系列閘瓦制動(dòng)器的操作裝置。

    (1)海拔高度不超過2500m;
    (2)周圍空氣溫度不高于+40℃及不低于-25℃:
    (3)空氣相對濕度不大于90%(該月的平均最低溫度不超過+25℃);
    (4)在無爆炸危險(xiǎn)的介質(zhì)中,且介質(zhì)中無足以腐蝕金屬和破壞絕緣的氣體與塵埃(包括導(dǎo)電塵埃);
    (5)在沒有雨雪侵襲的地方;
    (6)無顯著搖動(dòng)和沖擊振動(dòng)的地方:
    (7)安裝類別為川類,污染等級為3級的場合。

    電磁鐵制成敞開式,防護(hù)等級為IP00。
    電磁鐵主要是由鐵芯、銜鐵及線圈三大部分組成的回轉(zhuǎn)拍合式的工作結(jié)構(gòu)。
    ※當(dāng)線圈通電時(shí),銜鐵被吸合到鐵芯上,這時(shí)銜鐵通過停檔壓在制動(dòng)桿上迫使制動(dòng)桿移動(dòng),從而使制動(dòng)器閘瓦松開。當(dāng)電源切斷時(shí),制動(dòng)器在彈簧的作用下,使銜鐵離開鐵芯,則制動(dòng)器將閘瓦抱緊,達(dá)到制動(dòng)效果。

    電磁鐵的工作制有間斷長期工作制及反復(fù)短時(shí)工作制,額定工作電壓為交流50Hz,220V、380V兩種。
    ※長期工作制即TD=100%,其每小時(shí)動(dòng)作次數(shù)不超過20次,反復(fù)短時(shí)工作制即TD40%,每小時(shí)操作次數(shù)不超過300次。
    ※在正常工作條件下對反復(fù)短時(shí)工作制的電磁鐵壽命為60萬次。
    電磁鐵在電壓不低于85%額定工作電壓時(shí),其技術(shù)數(shù)據(jù)見表1所示

    注:電磁鐵的轉(zhuǎn)矩不包括銜鐵重量所產(chǎn)生的轉(zhuǎn)矩

    安裝前應(yīng)核對電磁鐵銘牌數(shù)據(jù)是否與需要相符,然后用手拉動(dòng)電磁鐵的銜鐵,使其能自由落下,不應(yīng)有卡住現(xiàn)象。
    電磁鐵安裝在TJ2系列制動(dòng)器上時(shí)應(yīng)先將制動(dòng)器上的安裝板條卸下.裝于電磁鐵安裝孔,然后將其裝于制動(dòng)器上。
    在安裝電磁鐵時(shí)應(yīng)注意.調(diào)整至制動(dòng)器上的制動(dòng)桿應(yīng)頂在電磁鐵停檔的中間部位。
    電磁鐵裝在制動(dòng)器上后,應(yīng)將螺栓、螺母擰緊,并應(yīng)調(diào)整制動(dòng)器的制動(dòng)桿,使制動(dòng)桿的位移不大于表1所列的數(shù)據(jù)。
    接上電源通以額定工作電壓,調(diào)整制動(dòng)器閘瓦制動(dòng)輪之間的間隙(注意通電時(shí)間應(yīng)與通電持續(xù)率相符),間隙距離見制動(dòng)器使用說明書。
    定期檢查線圈的接線片是否脫焊、松動(dòng),銜鐵是否因污垢而卡住,銜鐵的行程,制動(dòng)桿位移是否符合要求,緊固件是否擰緊等。
    定期在活動(dòng)部件加上少量潤滑油(制動(dòng)器的閘帶上切不能加油)。
