釜用机械密封选型、使用、安装

一、订货前必须详细提供配套设备的轴径、压力、温度、转速、密封介质及轴的旋向。
二、跟据参数，正确选择相应型号的机械密封及使用材料。
三、釜用双端面机械密封使用压力高于0.8Mpa，需配平衡罐装置。
四、介质温度高于200°C，需要选用双冷却结构密封。
五、轴的径向摆动≤0.5mm，表面粗糙度不低于1.6（△6）外径制造公差为-0.02，倒角并修光滑。
六、轴封装配密封的釜口法兰，不垂直度为≤0.5mm。
七、釜用单端面机械密封弹簧压缩量，按图规定进行允许误差正负1mm。
八、清洗所有零件，在轴上及摩擦面涂少量的润滑油，使动环能在轴上灵活滑动。
九、机械密封安装后应用水试运转24小时候再正式投料生产。

Ordering,Usage and Installation forPump-using Mechanical Ssals

1.Information about axial diameter,pressure,temperature,rotative-velocity Sealing media and rotary-orientatin of corollary equip- ments shoulc bi provided in detail before ordering.
2.Choose corresponding types of machanical seals and necessary necessary materials according to the parameters.
3.Balancing tank should be applied when the pressure is high than 0.8Npa(refer to figureabove)
4.Dual-cooling stucture must be used when the media temperature is high than 200°C.
5.The axial float of the shaft is no more than 0.5mm .
6.The permitted non-perpendicularty of the shaft and the flange for installing machanical seals is 0.05mm.
7.The produding to learance of the shaft in the place where machanical seals would be installed is d4 and the fineness is.
8.When the installation is done, the should be a trial run with water for 24 hours before staeting production.
