    • A vibration-reducing structure for compressing diaphragm pump features a pump head body and a diaphragm membrane. The pump head body includes four operating holes, a first curved vibration-reducing positioning structure circumferentially disposed around the upper side of each operating hole, and or a linked four-curve positioning structure that collectively extends around all of the operating holes. The diaphragm membrane includes four equivalent piston acting zones and second curved vibration-reducing position structures situated at positions corresponding to the positions of the first curved vibration-reducing positioning structures. The first positioning structures in the pump head body, which may be grooves, slots, perforations, or protrusions, mate with the corresponding second positioning structures in the diaphragm membrane to reduce the moment arm generated during pumping by movement of the diaphragm membrane, which may be protrusions, grooves, slots, or perforations, thereby generating less torque to decrease the strength of vibrations and vibration noise.
    • 用于压缩隔膜泵的减振结构具有泵头体和隔膜。 泵头本体包括四个操作孔,围绕每个操作孔的上侧周向设置的第一弯曲减振定位结构,以及围绕所有操作孔共同延伸的连接的四曲线定位结构。 隔膜包括位于与第一弯曲减振定位结构的位置对应的位置处的四个等效活塞作用区和第二弯曲减振位置结构。 泵头本体中的第一定位结构(其可以是凹槽,狭槽,穿孔或突起)与膜片膜中的相应的第二定位结构配合,以减少通过隔膜的运动在泵送期间产生的力矩臂, 是突起,凹槽,槽或穿孔,从而产生较少的扭矩以降低振动和振动噪声的强度。
