（１）膠管在移動或靜止中，均不能過度彎曲，也不能在根部彎曲，至少要在其直徑的1.5倍處開始彎曲；

     （２）膠管移動到極端位置時不得拉得太緊，應比較松弛；

     （３）盡量避免膠管的扭轉變形；

     （４）膠管盡可能遠離熱輻射構件，必要時裝隔熱板；

     （５）應避免膠管外部損傷，如使用中同構件表面的長期摩擦等；

     （６）若膠管自重引起過分變形時，應有支托件。

(1) The hose should not bend excessively or at the root, at least at 1.5 times its diameter, when it is moving or stationary.

(2) When the hose moves to the extreme position, it should not be pulled too tightly and should be relatively relaxed.

(3) Avoid torsional deformation of rubber hose as far as possible;

(4) Rubber hoses should be as far away from thermal radiation components as possible, and heat insulation panels should be used when necessary.

(5) External damage of the hose should be avoided, such as long-term friction with the surface of the component in use.

(6) If the weight of the hose causes excessive deformation, support shall be provided.
