Especially the area of rotating sealing faces has to be minimized to the minimum , even under higher - pressure environment 特别的是旋转封闭面大小必须减低到最低限度,甚至在较高的压力下。
The inner mechanical seal shall be constructed with a solid block carbon rotating seal face and a solid block silicon carbide stationary seal face 内置的机械密封结构应该采用一块整体结晶碳旋转密封面和一块整体结晶碳化硅固定密封面。
The outer mechanical seal shall be constructed with a solid block silicon carbide rotating seal face and a solid block silicon carbide stationary seal face 外置的机械密封应该采用一块整体结晶碳化硅旋转密封面和一块整体结晶碳化硅固定密封面。
For motor frame size 180 and above , the inner mechanical seal shall be constructed with a solid block carbon rotating seal face and a solid block silicon carbide stationary seal face 用于尺寸180以上的电机机架,内置的机械密封结构应该采用一块整体结晶碳旋转密封面和一块整体结晶碳化硅固定密封面。
