ìŸIiAÆlObbs.3c3t.com9;T£$_M

1、应有铭牌,其中包括制造厂、型号、规格出厂编号与日期。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

2、外表面应平整光洁,振动平稳,声音正常,台面应水平。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

3、电气部件绝缘性能应良好。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

4、基座与基础用地脚螺栓固定。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

5、振动台面尺寸:1000×1000±5mmìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

6、振动频率:50±3HZìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

7、空载时的有效振幅为0.5±0.1mmìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

三、校验用标准器具ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

8、二级测振仪;ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

92m长钢卷尺,分度值1mmìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

四、校验方法ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

(一)外观与工作状态校验ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

10、用感官和启动试验检查,要符合1234条规定。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

(二)技术参数校验方法:ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

11、用钢卷尺测量振动台面的尺寸。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

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。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

13、振动频率可根据电机转速测定,也可以采用测振仪测定。 ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

五、校验结果评定ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

14、新振动台必须全部符合技术要求。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

15、使用中的振动台应符合67条技术要求。ìŸIiAÆlObbs.3c3t.com9;T£$_M

ìŸIiAÆlObbs.3c3t.com9;T£$_M

16、校验周期壹年。ìŸIiAÆlObbs.3c3t.com9;T£$_M
