关于保存和维护闲置的阀门的几点建议定期保养闲置时间较长的阀门，应定期检查，定期保养，防止阀门锈蚀和损坏。对于闲置时间过长的阀门，应与设备、装置、管道一起进行试压合格后，方可使用。防护保护防止他物撞击，人为搬弄和拆卸，必要时，应对阀门活动部位进行固定，对阀门进行包装保护。防蚀处理掏出填料函中的盘根、防止阀杆电化腐蚀，阀门密封面、阀杆、阀杆螺母、机加工表面等部位，视具体情况防锈剂、润滑脂，涂漆部位应涂刷防锈漆。

从功能看，伺服的功能主要是：1、速度控制 2、转矩控制 3、位置控制（含和跟踪）；从控制看，伺服一般是三环系统：外环位置环，内环依次为速度还和电流环 3. 其实现实应用中大多数设备对电机的控制性能要求不高，对比伺服：其调速范围一般是：1:100（无编码器）/1:1000(带编码器），转矩：1.5倍额定即可；电机和驱动器的技术难度、方案及配置、价格都大幅度降低；而且功率范围宽，从几百瓦到上千KW不等；由于应用在各行各业，所以变频器的功能特别丰富，为了满足特定行业的需求，许多厂家都在开发行业专用型变频器，比较典型的有：电梯专用变频器、供水专用变频器等；价格低，覆盖范围宽是变频器的主要特点；电机可以是异步电机，也可以是同步电机；一般变频器只包括速度控制和电流控制两个环节；

镀锌槽中极间距离，阴极与阳极的相对位置对镀层均匀性也有影响。生产中钢丝应距阳极锌板3～4mm，并在相应的隔板中间平稳运行，不得与隔板或底座阳极相刮擦运行，不得露出液面。锌阳极板采用热铸法制造，锌板必须装入锌板套(阳极套)中，阳极套要定期检查更换，保持完整。每班检查锌板消耗情况，当锌板消耗2/3时，应立即更换，使阳极锌板、电极铅板与电极母线触头接触良好，保证阳极锌板处于正常溶解状态。钢丝在运行过程中，应被负极枪液面下2～3mm，负极枪与钢丝接触面的平整度应达到枪顶部直角口与钢丝平行接触，顶部的电解生成堆积物要清除干净，每班要检查清洗阴极枪头部，保证阴极枪与钢丝的良好接触状态。
