女人天天干夜夜爽视频 渣浆泵机械密封的特点
    优点:机械密封设有由弹性元件、铺助密封圆等构成的轴向磨损补偿机构，因此其泄漏量极小；寿命长，一般为1~2年:对抽的摩擦小；可自动运行而不需在运行时调正；功率损失小，只有填料密封的1/3-1/10,耐振动性好；使用广泛；目前转速可达17000r/min，压力达到30MPa。
    缺点:零件多，精度高，相应造价高；由于动密封面垂直于旋转轴线，所以安装时的对中非常重要。

Characteristics of mechanical seal for slurry pump

Advantages: the mechanical seal is equipped with an axial wear compensation mechanism composed of elastic elements, auxiliary seal circles, etc., so its leakage is very small; its service life is long, generally 1-2 years; the friction of the opposite pump is small; it can operate automatically without adjusting during operation; the power loss is small, only 1 / 3-1 / 10 of the packing seal, with good vibration resistance; it is widely used; at present, the rotating speed can reach 17000r / min, and the pressure can reach 30MPa.

Disadvantages: there are many parts, high precision and high cost; since the dynamic sealing surface is perpendicular to the rotating axis, the centering during installation is very important.
