渣(zhā)漿(jiāng)泵機械密封(fēng)的特(tè)點

渣(zhā)漿泵機械密封(fēng)的特點
    優點:機(jī)械密(mì)封設(shè)有由(yóu)彈性(xìng)元件(jiàn)、鋪(pù)助密封(fēng)圓等(děng)構成的軸(zhóu)向磨(mó)損補償機(jī)構，因(yīn)此其洩漏(lòu)量極(jí)小；壽命長，一般為1~2年:對抽的摩擦小(xiǎo)；可(kě)自(zì)動運行而(ér)不需(xū)在運行(háng)時調正(zhèng)；功率損失(shī)小，隻(zhī)有填(tián)料密封的(de)1/3-1/10,耐振動(dòng)性好；使(shǐ)用(yòng)廣(guǎng)泛(fàn)；目(mù)前轉速可(kě)達(dá)17000r/min，壓力達(dá)到(dào)30mpa。
    缺點:零件多(duō)，精(jīng)度高，相應造價高；由(yóu)于(yú)動密封面垂直(zhí)于旋轉(zhuǎn)軸線，所(suǒ)以安裝時(shí)的對(duì)中非常重要。

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.
