渣漿(jiāng)泵機械(xiè)密封的(de)特點

渣漿(jiāng)泵機械(xie)密封的(de)特點
    優點:機械(xie)密封設(she)有由彈性元(yuan)件、鋪(pù)助密封(fēng)圓等構(gou)成的軸向磨損(sun)補(bu)償機構(gòu)，因此其(qí)洩漏量極小；壽(shou)命長，一般為1~2年:對抽(chou)的摩擦小；可自動(dong)運行而(ér)不需在(zai)運行時(shi)調正；功率損失小(xiao)，隻有(you)填(tian)料密封的(de)1/3-1/10,耐振動(dong)性好；使用廣(guǎng)泛；目(mù)前轉速(su)可達17000r/min，壓(yā)力達到(dào)30MPa。
    缺點:零件多，精度高(gao)，相應(ying)造價高(gao)；由于動密(mi)封面垂(chui)直于旋轉軸(zhóu)線，所以(yǐ)安裝時的對(dui)中非常重(zhòng)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.
