DO Type Mechanical Face Seal introduction
DO type is standard mechanical face seal composed of two metal parts.This design consists of two symmetrically tapered seal rings and two O-rings. At installation, the o-rings are compressed between thetapered contact surfaces of the seal ring and housing.The o-rings undergo a calculated compression whichis critical for proper operation of the sealing system(dimension “S”). Cleanliness of the o-rings and housing
(free of oil and dirt) is of primary importance. Lubrication of the o-rings with oil or grease is not permitted during the installation process.
产品描述
浮动油封概述
浮动油封由两个相同的金属钢环及两个橡胶圈组成，其工作原理是一对金属环在一对橡胶圈的支撑下与腔体形成一个封闭的空间（但不与轴接触），运转时金属环的两个经过研磨的密封表面紧密配合并相对滑动，一方面保证运行良好，另一方面有效封隔外界的灰尘、水、泥石、砂砾等，保护内部的润滑油脂不泄漏，产品类型有DO型、DF 型以及XY型。
