1、保护罩折面材料根据工作条件选择PVC（聚氯乙烯
）材料和其它材料；
2、每个折面下的PVC片材支撑；
3、能避免在高速度下产生噪音的滑动片；
4、高频焊接；
5、固定用的支撑面； |
1、Special coated fabric,chosen according to
working condition.
2、Rigid PVC supportin every fold.
3、Special shoes to prevent annoying noises at high speeds.
4、High freqrency welding.
5、Fastening flange.

在设计阶段为了估算保护罩的体积；可参考下面的有关参数：
 标准折面的高度：
15mm、20mm、30mm、35mm、40mm、45mm、52mm；
机械设备的导轨面和护罩之间的距离量小为5mm、最大为10mm;
护罩折面张开时的尺寸等于这个折面高度的壹倍；
被压缩折面厚度等于4mm;
风箱被压缩后的长度等于；
折叠保护器张开尺/一个折面张开尺寸×（3-4.5mm）＋支架厚度

To calculate the dimensions
of the welded bellow at the design stage,it is useful to pay
mind tsome data:
The standard folds
have the following heights:15mm、20mm、30mm、35mm、40mm、45mm、52mm.
The total play between
the slides and the bellow must be from a minimum of 5mm.toa
maximum of 10mm.
The extension of
one fold is equivalent to twice the fold 's height minus 10mm.
The thickness of
a compressed folds is om average 4mm.
The compressed lenght
of the bellows is eqral to:
extension of bellow/extenion of one fold×(3-4.5mm.)＋flange thicknesses |
