渣(zha)漿泵機(ji)械密封(feng)的特點(dian)

渣(zha)漿泵機(jī)械密封(fēng)的特點(diǎn)
    優點(dian):機(jī)械密封(feng)設有由(yóu)彈(dan)性(xing)元件、鋪助密(mì)封圓等(děng)構成的(de)軸(zhou)向(xiàng)磨(mo)損補償機(jī)構，因此(cǐ)其洩漏量(liàng)極(jí)小(xiǎo)；壽命長，一般為(wei)1~2年(nián):對(duì)抽的摩擦(cā)小(xiao)；可自(zi)動運行(hang)而不需(xu)在運行(háng)時調正(zheng)；功率損失(shī)小，隻(zhī)有填料密(mì)封(fēng)的1/3-1/10,耐振(zhèn)動性好(hao)；使用(yòng)廣泛；目前轉(zhuan)速可達(dá)17000r/min，壓力達(dá)到30MPa。
    缺點:零件多(duō)，精(jīng)度(dù)高，相(xiàng)應造價(jià)高；由(you)于(yú)動(dong)密封面(miàn)垂直于旋轉(zhuǎn)軸線，所(suo)以安裝時的(de)對中非常(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.
