摘要： A hydraulic plunger installation tool that exerts a hydraulic force on a plunger for a reciprocating pump to install the plunger into a pump cylinder opening. Maintenance of the pump typically includes repacking of the packing that surrounds the plunger and revalving of the pump's inlet and outlet valve. To allow repacking or revalving, the pump is disassembled and the plunger is removed. The hydraulic plunger installation tool is located at the pump cylinder on an upward facing nest with legs that provide a reaction point for a hydraulically actuated piston rod that is driven at one end by a hydraulic piston and engages the plunger at an opposite end during installation to push the plunger into the cylinder opening without the use of hammers by personnel.

摘要： A grooved perforated layer for use in a papermakers' fabric is provided. The grooves serve to diffuse flow at the surface of the perforated layer so as to reduce the pressure drop across the layer and thereby reduce the migration of fines. In this manner, the light/dark pattern associated with the fines is avoided and the quality of the resulting paper sheet is improved.
摘要翻译：提供了一种用于造纸织物的开槽孔。这些凹槽用于在穿孔层的表面扩散流动，以便减少穿过该层的压降，从而减少细粒的迁移。以这种方式，避免了与细粉相关的亮/暗图案，并提高了所得到的纸张的质量。

摘要： A method and apparatus for reducing the amount of rewet of in a press section of an industrial press including a press fabric for carrying a sheet, a press for applying pressure to the press fabric and for forcing water out of the sheet and into the press fabric, and means for applying a reusable displacing agent to at least one side of press fabric, the displacing agent absorbing interfacial water upon exiting the press and preventing rewet of the sheet.
摘要翻译：一种用于减少包括用于承载片材的压榨织物的工业压力机的压榨部分的再润湿量的方法和装置，用于向压榨织物施加压力并迫使水从片材中压出并进入压榨织物的压力机以及用于将可重复使用的置换剂施加到压榨织物的至少一侧的装置，所述置换剂在离开压机时吸收界面水并防止片材的再润湿。
