渣漿泵機械密(mi)封的特點

渣漿泵機械密(mi)封的特點
    優點:機械密封設有(yǒu)由彈性元件、鋪助密封圓(yuán)等構成的軸向磨損補償(cháng)機構，因此其洩(xiè)漏量極小；壽命(mìng)長，一(yī)般為1~2年:對抽的(de)摩擦小；可(ke)自動運行而不(bú)需在運行時調(diao)正；功(gōng)率損(sun)失小，隻有填料(liao)密封的1/3-1/10,耐(nai)振動性好；使用廣泛(fàn)；目前(qian)轉速可達17000r/min，壓力(li)達到30MPa。
    缺點(diǎn):零件(jian)多，精度高，相應造價高；由于動密封(feng)面垂直于(yú)旋轉軸線(xiàn)，所以安裝(zhuāng)時的對中(zhōng)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.
