渣漿泵機械密(mi)封的特點

渣漿泵(beng)機械密封的特點(diǎn)
    優點:機械密封設有(yǒu)由彈性(xìng)元件、鋪(pù)助密封圓等構成(cheng)的軸向(xiang)磨損補(bu)償機構，因此其洩(xie)漏量極(ji)小；壽命長，一般(ban)為1~2年:對(duì)抽的摩擦小；可(ke)自動運行而不需(xū)在運行時調正；功率(lǜ)損失小，隻有填(tian)料密封的1/3-1/10,耐振(zhèn)動性好；使用廣泛；目前轉速可達(dá)17000r/min，壓(ya)力達到30MPa。
    缺點:零件多，精度高，相應造價(jia)高；由于動密封(feng)面垂直于旋轉軸線，所以(yi)安裝時(shí)的對中非常(cháng)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.
