渣漿泵機械密封的特點
優(yōu)點:機械密封設(shè)有由彈性元件、鋪助密封圓等構(gòu)成的軸向磨損補償機構(gòu),因此其泄漏量極??;壽命長,一般為1~2年:對抽的摩擦小;可自動運行而不需在運行時調(diào)正;功率損失小,只有填料密封的1/3-1/10,耐振動性好;使用廣泛;目前轉(zhuǎn)速可達17000r/min,壓力達到30MPa。
缺點:零件多,精度高,相應(yīng)造價高;由于動密封面垂直于旋轉(zhuǎn)軸線,所以安裝時的對中非常重要。
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.
