说明：180°弯曲安装，长度过短时，会产 生过度弯曲；应大于最小弯曲半径安装。

180 ° bend,radius should belarge than min bend radius to avoid bend excessive.

说明：不允许小于最小弯曲半径，应安装刚 性弯头。

Avoid impermissible deflection behind the connection fittings by use for rigid pipe bends,observe Min bending radius.

说明：运动方向与软管轴线应在同一平面 内，以避免产生扭转应力。

Direction of movement and hose axis must lie in one plane to avoid torsion stress.

说明：长度较长时，易出现下垂，此时应安 装滚筒和托架。

Protect the hose line form sagging behind the fittings by means of a support,A pulley or guiding may be installed.

说明：避免产生交变应力，安装刚性弯头以 消除交变应力和过度弯曲。

Installing rigid pipe bends to avoid torsion stress and bending excessive.

说明：运动方向与软管轴线在同一平面内， 以避免产生扭转应力。

Direction of movement and hose axis must lie in one plane to aviod torsion stress.

说明：运动方向与软管轴线应在同一平面 内，以避免产生扭曲损坏。

Direction of movement and hose axis muse lie in one plane to avoid torsion stress.

说明：自由弯曲安装时，软管应避免墙壁、 其他物体和地面磨擦。

Avoid rubbing between hose and wall,ground by appllying appreciate method.

说明：应安装滚轮避免过度弯曲。

Avoid excessive bending stress by a pulley.

说明：即使在普通场合，也安装刚性弯头以 避免过度弯曲。

Avoid bengding excessice by application of rigid pipe bend.

说明：如无法避免外部机械拉伸（如在地面 上频繁拖动），应外覆保护层。

If there is no possibility of avoiding exterior mechanical strain(such as dragging frequency on the ground),the protection wrap.
