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

产品介绍

MZD1系列交流单相制动电磁铁(以下简称电磁铁)适用于交流50Hz额定电压至380V的电路中。主要作为匹配TJ2系列或JWZ系列闸瓦制动器的操作装置。

(1)海拔高度不超过2500m;
(2)周围空气温度不高于+40℃及不低于-25℃:
(3)空气相对湿度不大于90%(该月的平均最低温度不超过+25℃);
(4)在无爆炸危险的介质中,且介质中无足以腐蚀金属和破坏绝缘的气体与尘埃(包括导电尘埃);
(5)在没有雨雪侵袭的地方;
(6)无显著摇动和冲击振动的地方:
(7)安装类别为川类,污染等级为3级的场合。

电磁铁制成敞开式,防护等级为IP00。
电磁铁主要是由铁芯、衔铁及线圈三大部分组成的回转拍合式的工作结构。
※当线圈通电时,衔铁被吸合到铁芯上,这时衔铁通过停档压在制动杆上迫使制动杆移动,从而使制动器闸瓦松开。当电源切断时,制动器在弹簧的作用下,使衔铁离开铁芯,则制动器将闸瓦抱紧,达到制动效果。

电磁铁的工作制有间断长期工作制及反复短时工作制,额定工作电压为交流50Hz,220V、380V两种。
※长期工作制即TD=100%,其每小时动作次数不超过20次,反复短时工作制即TD40%,每小时操作次数不超过300次。
※在正常工作条件下对反复短时工作制的电磁铁寿命为60万次。
电磁铁在电压不低于85%额定工作电压时,其技术数据见表1所示

注:电磁铁的转矩不包括衔铁重量所产生的转矩

安装前应核对电磁铁铭牌数据是否与需要相符,然后用手拉动电磁铁的衔铁,使其能自由落下,不应有卡住现象。
电磁铁安装在TJ2系列制动器上时应先将制动器上的安装板条卸下.装于电磁铁安装孔,然后将其装于制动器上。
在安装电磁铁时应注意.调整至制动器上的制动杆应顶在电磁铁停档的中间部位。
电磁铁装在制动器上后,应将螺栓、螺母拧紧,并应调整制动器的制动杆,使制动杆的位移不大于表1所列的数据。
接上电源通以额定工作电压,调整制动器闸瓦制动轮之间的间隙(注意通电时间应与通电持续率相符),间隙距离见制动器使用说明书。
定期检查线圈的接线片是否脱焊、松动,衔铁是否因污垢而卡住,衔铁的行程,制动杆位移是否符合要求,紧固件是否拧紧等。
定期在活动部件加上少量润滑油(制动器的闸带上切不能加油)。
