Some problems in development and application of novel epoxy resin - based lubricative and wear - resistant coatings 新一代环氧润滑耐磨涂层研制与应用中需解决的若干问题
Cw the feature of cw magnetic - driving vortex pumps is little capacity , high - head , it can convey the fluid containing 20 percent of gas and non - lubricative , also can be used to the occasion where npsh is low Cw型磁传动旋涡泵,是小流量高扬程应用最理想的选择;可输送含有20 %气体的介质,可应用于非润滑性流体和汽蚀余量很低的场合。
Machinery can product higt precisely and stably . all the machine parts and components are made by adopting the hith quality material , strong struction , durative lubricative system to make the machine working smoothly and decrease the frication damage 全部机器采用优质材料,结构坚固,强制润滑系统使机器运转顺利并且可十分有效地减少磨损。
The intubatton operating side of the lens body is smeared with the lubricative silicon oil , which can effeictively eliminate the friction resistence between the lens body and the trachea and hence make the clinic operation much more convenient 麻亮爽镜体的插管操作面涂有润滑硅油,有效地消除了气管导管与镜体的摩擦阻力,临床操作更加方便。
Piston plated by 0 . 5 - 3u tin on the surface in chemical way , the tin layer with little hole has the lubri - cative quality of soft metal . it can absorb more lubricative oil to drop the friction between the piston and cylinder 在活塞表面用化学方法镀覆05 . - 3的锡层,多孔的锡层有软金属的良好润滑特性,能吸附较多润滑剂,降低了活塞与气缸音的摩擦功
