为了解决目前使用的活塞在结构上存在的问题,Weatherford/DMC设计人员经过若干年的研究,制成一种全新式活塞——耐用活塞(如图1所示)。 传统的泥浆泵活塞是通过硫化压铸成型,或在金属的活塞芯子上装上可拆卸的胶皮密封
To address the structural problems of the currently used pistons, Weatherford / DMC designers made years of research into a new piston-durable piston (Figure 1). The traditional mud pump piston is molded by vulcanization or a removable rubber seal is mounted on the metal piston core
