Form fort he correct assembly of ATEX fans
ATEX 防爆风机的正确安装
With ATEX-certified fans, this form must be completed by the fitting team.
It serves to verify the proper mounting of the fan and its operating conditions.
The completed form must be kept by the safety officer or operating company.
It forms the basis of a test voucher quality system which is stipulated by standard EN 14986 (Design of fans
for use in explosive atmospheres).
针对 ATEX 防爆风机，本表格需要由执行团队完成。
它用来判断风机安装是否正确，工作条件是否符合要求。完成后的表格由安全专员或者公司保留。
根据 EN14986（危险环境用风机的设计）的规定，该表格构成了风机质量测试证明系统的基础。
The fitting team shall certify that they have properly executed the following work:
执行团队应该确保正确的执行了下列规定
The fan is mounted on suitable vibration dampers. They are mechanically secured so that the fan
cannot slip away or wander.
风机安装了正确的防震垫，能保证风机不侧滑和晃动。
For the transitions from the fan to the duct system, elastic sleeves were used to prevent any
vibrations from being transferred to the fan.
风机和管道系统之间的转接部分，安装有弹性软接头来防止振动传导至风机。
The intake and pressure ducting are connected close to the fan.
进风和排风管道系统靠近风机连接。
With free intake/blow off fans, a protective grating with a mesh width of 10mm is fitted.
风机敞开进风，要安装防护罩，网眼宽度 10mm。
The clearance between the impeller and the casing is min 5mm and max 20mm.
叶轮和壳体之间的间隙最小 5mm，最大 20mm。
All rotating parts are protected against unintentional contact.
所有的旋转部件都有防护措施，避免意外的接触。
The fan is installed so that the motor is supplied with sufficient cooling air (distance to walls, etc.)
风机安装时要给电机留足通风空间（距离墙壁的距离等）。
The motor is properly connected in accordance with the manufacturer's instructions (operating
manual). The same applies to the PTC resistor, if fitted.
根据厂家的说明（使用手册）正确的连接电机。PTC 热敏电阻的安装遵循同样的规则。
The motor and the fan is connected to a potential equalisation system.
电机和风机连接到一个潜在的均衡系统。
Test run 运行测试:
The minimum air flow through the fan is min 3 m/s and max 30m/s.
风机最小风速 3m/s, 最大风速 30m/s。
The maximum vibration velocity in operation is not greater than 5.1mm/s measured at the bearings
(V-belt drive) or the motor (direct drive).
风机运行过程中，轴承（风机轴承或者电机轴承）的最大振动速率不能超过 5.1mm/s。
The operating temperature is lower than the maximum permitted operating temperature specified on
the rating plate.
风机运行温度要低于铭牌上标注的最高工作温度。
The motor current draw is lower than the rated current specified on the rating plate.
电机工作电流要低于铭牌上标注的额定电流值。
If one or more of the works listed above cannot be carried out, please contact the supplier of the
manufacturer.
如果上述要点有一条或者更多不能被执行，请联系风机厂家。
