MARZOCCHI泵简介
外齿轮泵是现代液压系统中最常用的泵。它们具有多功能性，强度和长使用寿命。其简单的结构确保了有限的购买成本和维修。
凭借这些基本概念，以及不断改进的产品设计和功能，研究 - 基于多年的经验 - 材料选择的准确性，生产过程非常详细和大规模生产零件的测试，齿轮泵已达到顶峰。因此，产品可以在恶劣的工作条件下工作并传输高液压动力。此外，Marzocchi泵具有良好的液压，机械和容积效率，低噪音水平，最后但并非最不重要的是，紧凑的尺寸和低重量/功率比。
齿轮泵通常包括由两个铝衬套支撑的齿轮副，用于0.25,0.5和1P组，或带有滑动轴承的衬套，涂有减摩材料，用于组1,2,3和4，主体，固定法兰和盖子。伸出凸缘的驱动齿轮轴安装一个双唇密封圈（内唇为密封圈，外唇为防尘密封圈），用于0.25,0.5和1P组，或两个相对的单唇密封圈（对于第1,2,3和4组），外部是防尘密封。
泵体，法兰和盖子由特殊的高抗铝合金制成，即使在高压下，无论是连续的还是间歇的或峰值压力，都能最大限度地减少变形。主体通过挤压成型，而法兰和盖子通过压铸获得（对于某些型号甚至是重力压铸）。
齿轮由特殊钢制成。他们的制造过程包括表面硬化和淬火硬化。然后对齿轮进行磨削和精加工，以获得高度的表面光洁度。适当的齿形设计和几何比例确保泵运行期间的低脉动水平和低噪音水平。衬套由特殊的低摩擦和高抗铝合金制成，并由压铸制成。
法兰和盖板上的特殊补偿区域通过带有防挤出环的特殊密封件进行绝缘，允许轴向和径向完全自由移动到衬套，这与泵的工作压力成正比。通过这种方式，内部滴落大大减少，从而确保非常好的泵性能（在体积和一般方面）和泵运动部件的适当润滑。
External gear pumps are the most popular pumps used in modern hydraulic systems. They feature versatility, strength and long useful life. Their simple construction ensures limited purchase costs and servicing.
Thanks to these basic concepts, together with ever-improving product design and features, research -based on many years of experience - accuracy in material selection, production process followed in great detail and tests on mass-produced parts, our gear pumps have reached top quality standards. For this reason, our products can work under heavy operating conditions and transmit high hydraulic power. Furthermore, Marzocchi pumps feature good hydraulic, mechanical and volumetric efficiency, low noise level and, last but not least, compact dimensions and low weight/power ratio.
A gear pump usually consists of a gear pair supported by two aluminum bushes for groups 0.25, 0.5 and 1P, or bushes with plain bearings coated with antifriction material for groups 1, 2, 3 and 4, a body, a securing flange and a cover. Shaft of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal, the outer lip being a dust seal) for groups 0.25, 0.5 and 1P, or two opposed single-lip seal rings (the outer being a dust seal) for groups 1, 2, 3 and 4.
Pump body, flange and cover are made of special hi-resistant aluminum alloys for minimized deformation even when subject to high pressure, be it continuous or intermittent or peak pressure. The body is profiled by means of extrusion, whereas flange and cover are obtained by means of die-casting (even gravity die-casting for some models).
Gears are made of special steel. Their manufacturing process includes case-hardening and quench hardening. Then gears are ground and fine finished so to have a high degree of surface finishing. Proper tooth profile design and geometric proportions ensure low pulsation levels and low noise levels during pump operation. Bushes are made of special low-friction and hi-resistant aluminum alloy and manufactured from die-casting.
Special compensation zones onto flange and cover, insulated by special seals with anti-extrusion rings, allow fully free axial and radial movement to the bushes, which is proportional to pump operating pressure. In this way, internal dripping is dramatically reduced, thus ensuring very good pump performance (both in terms of volume and in general) and proper lubrication of pump moving parts.
