渣(zha)漿泵機械密封的(de)特點

渣漿泵機械(xie)密封的特點
    優點:機(ji)械密封設有由彈性元件(jian)、鋪助密(mì)封圓等構成的軸向磨損補償機(jī)構，因此其洩漏量極小；壽命長，一般為1~2年:對抽的(de)摩擦小(xiǎo)；可自動(dòng)運行而不需在運(yun)行時調正；功率損失小，隻有填料密(mi)封的1/3-1/10,耐振動性(xing)好；使用(yong)廣泛；目(mù)前轉速可達17000r/min，壓力達(dá)到30MPa。
    缺點:零(ling)件多，精(jing)度高，相應造價高；由于(yu)動密封面垂(chuí)直于旋(xuán)轉軸線，所以安裝時的對(dui)中非常重要(yào)。

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.
