【中英文】不锈钢金属软管安装说明“全球通”

Key factors for installation
安装的关键因素
 
Following advises are however to be taken into consideration in order to obtain a good performance and prolonged service life of the expansion joint.
注意:为了获得良好的性能和延长伸缩缝的使用寿命,必须考虑以下建议。

 
Fixed points
固定点
 
An expansion joint acts as a piston by the forces arising from the internal pressure.To prevent the pipes from damage they are to be properly anchored in order to take care of these reaction forces (Fr).
金属软管由内部压力产生的力作用于活塞,为了防止管道受到损坏,必须将管道固定起来,以处理这些反作用力(FR)。
The Reaction force of an expansion joint is calculated by the following formula:
金属软管的反力计算公式如下:
Fr = Q x P x 0.01
Fr = reaction force in kN.
Q = effective cross sectional area in cm2.
P = actual pressure in bar or kp/cm2

 
Mounting
安装
 
Before installation, the temperature, pressure and displacement of the product should be strictly used.
安装前应严格在产品允许的温度、压力和位移量范围内使用!
 
The expansion joints shall be easily accessible and open to regular supervision. Lt is recommended to let the expansion joints work in compression rather than stretching. Torsion is not permitted.
金属软管应很容易的定期检查。我建议金属软管的工作是压缩,而不是拉伸,更不允许扭转。
 
Maintenance instructions: observe whether the expansion jointt is over stretched and keep the expansion joint in normal length every month.
保养须知:每月要观察金属软管是否超位移拉长,保持金属软管在正常长度内使用。
 
In order to ensure the expansion capacity, the bolts should be kept as small as possible (not exceeding 2 mm or 3mm) to avoid damaging the metal hose body.
为了保证伸缩能力,装配螺栓要确保螺纹螺栓尽量少(不超过2毫米或3mm),以避免损坏金属软管本体。

 
Precaution
预防措施
 
When welding work is to take place the bellow has to be protected from welding heat and sparks.
当焊接工作发生时,金属软管本体必须防止焊接发热和火花。
 
Please install an effective chlorine removal device at the inlet of the pipeline (chloride content is not more than 25mg/l) to avoid excessive chlorine content and pinhole corrosion.
请在管道进水口加装有效去除氯离子装置(氯离子含量不超过25mg/l),避免水氯离子含量超标,产生针孔腐蚀。
