四、校验方法lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

(一)外观与工作状态校验lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

10、用感官和启动试验检查,要符合1234条规定。lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

(二)技术参数校验方法:lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

11、用钢卷尺测量振动台面的尺寸。lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

12、用测振仪测振动台面的频率与有效振幅时,应待振动台振动平稳后测,测振点布置在振动台的四周边,共4点(如图一所示)如不能同时测四个点时,至少要同时测2个点。先测12点,后测34点。所测4个点均应符合第67条的要求。lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

13、振动频率可根据电机转速测定,也可以采用测振仪测定。 lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

五、校验结果评定lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

14、新振动台必须全部符合技术要求。lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û

lc‚Åì&Ί×bbs.3c3t.com:gH:UqÑ4°Û
