渣漿(jiāng)泵機械密(mi)封的特點(diǎn)

渣漿(jiang)泵機械密(mì)封的特點(dian)
    優點:機械密封(feng)設有由彈性元件、鋪(pu)助密封圓(yuan)等構成的(de)軸向磨損補償機構(gou)，因此其洩(xie)漏量(liang)極小；壽命(mìng)長，一般為1~2年:對(duì)抽的摩擦小；可自動(dòng)運行而不(bu)需在運行(hang)時調正；功(gōng)率損失小(xiao)，隻有填料密封的1/3-1/10,耐振動(dong)性好；使用(yong)廣泛；目前(qián)轉速可達(dá)17000r/min，壓力(li)達到30MPa。
    缺點(dian):零件多，精度高，相應(ying)造價高；由(yóu)于動密封(feng)面垂直于旋轉軸線(xian)，所以安裝時的對中(zhōng)非常(chang)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.
