D57Mo堆焊金属硬度较高，用于闸板；D577堆焊金属硬度较低，用于堆焊阀体或阀座密封面。两者组成的密封面可获得良好的抗擦伤性能。堆焊层的高度加工后应在5mm以上，以保证硬度和成份稳定。堆焊要按焊接工艺规定操作，焊接电流不可过大以防止焊条成份发生变化影响焊接质量。3硬质合金硬质合金中常用的是钴基硬质合金也称钴铬钨硬质合金。它的特点是耐腐蚀、耐磨、抗擦伤，特别是红硬性好，即在高温下也能保持足够的硬度，此外加工工艺性适中，其许用比压8～1MPa，国外资料介绍155MPa。
b大修后必须进行伏安特性试验，冷态试验和热态试验可以根据需要结合分部试运转及整体试运行时进行，以对设备进行评级和评价检修工作.电除尘器维修机械部分电场内部及灰斗积灰清除。用人工敲打等方法将电场内阴极框架极线、阳极板排及灰斗的积灰清除干净。阴、阳极间距检查调整：检查阳极板和阴极框架，对变形部分进行校正，保证极距偏差为1mm，使极距符合设计要求。振打装置检修。检查阴振打器连接及安装位置有无跑偏，振打锤是否与振打杆对中，逐个振打器进行调整校正，振打棒露出长度符合设计要求（382MM）；检查阳极振打是否正常，对存在问题进行处理。
量程变化范围从理论上讲为无限大，加之仪表输出信号与容积流量呈线性关系，其量程变换容易，故电磁流量计可制作成多量程及量程自动切换式仪表。智能电磁流量计的测量准确度和稳定性随着测量线路的合理化和集成化在不断提高，特别是微处理机的应用，使智能电磁流量计的准确度和抗干扰能力明显提高。因为智能电磁流量计对流体纵向速度分量敏感，对环流不敏感，所以流量计前后的直管段要求比其他流量计短。智能电磁流量计反应灵敏，能测定正、反方向的流体流量，可用以测脉动流量，其输出信号适于作为自动调节系统的流量信号。
不同的仪表有不同的k，并随仪表长期使用的磨损情况而变化。尽管涡量计的设计尺寸相同，但实际加工出来的涡轮几何参数却不会完全一样，因而每台涡轮变送器的仪表常数k也不完全一样，它通常是制造厂在常温下用洁净的水标定出来的。涡轮变送器输出的脉冲信号，经前置放大器放大后，送入显示仪表，就可以实现流量的测量[5]。涡轮流量计特点具有精度高、重复性好、无零点漂移、高量程比等优点。涡轮流量计拥有高质量轴承、特别设计的导流片，因此极大降低了磨损，对峰值不敏感，甚者恶劣的条件下也可以给出可靠的测量变量。
