## 文章

- [The function of gear pump](http://hbpumai.com/article/5666195321873841.html): Gear pump is a type of volumetric fluid machinery, whose core function is to achieve quantitative, high-pressure, and stable transportation of various fluids (mainly liquids, some of which can transport high viscosity pastes) through mechanical motion of gear meshing. At the same time, it can also achieve fluid pressurization or quantitative distribution according to demand. The essence of its function is to utilize the volume change of the sealed chamber formed by the rotation of gears to convert mechanical energy into pressure energy and kinetic energy of the fluid, thereby achieving directional transportation of the fluid.
- [What is the working principle of a gear pump?](http://hbpumai.com/article/5666195400805630.html): The core working principle of a gear pump is "volumetric suction and discharge" - by rotating a pair of meshing gears, a periodic sealed chamber volume change is formed inside the pump body. Through the process of "vacuum suction and extrusion discharge", mechanical energy is converted into pressure energy and kinetic energy of the fluid, achieving directional fluid transportation.
- [What are the applications of the working principle of gear pumps in practical life?](http://hbpumai.com/article/5666195418432871.html): The working principle of gear pumps (volumetric suction and discharge, quantitative high pressure, adaptability to high viscosity, strong self-priming ability) determines that they can adapt to the needs of "stable fluid transportation, especially in viscous/high-pressure scenarios" in daily life - from cars for daily travel, to industrial production, food processing, and even outdoor work tools, the practical application of their principles can be seen.
- [How to calculate the working pressure and displacement of hydraulic motors?](http://hbpumai.com/article/5666195554149780.html): The calculation of these two parameters is the basis for selecting hydraulic systems and matching working conditions (such as calculating working pressure based on load and selecting motors that match rated pressure; calculating displacement based on speed and flow rate to ensure sufficient power).
- [齿轮泵的作用](http://hbpumai.com/article/5666170023907042.html): 齿轮泵是一种容积式流体机械，核心作用是通过齿轮啮合的机械运动，实现定量、高压、稳定地输送各类流体（主要为液体，部分可输送高粘度膏体），同时可根据需求完成流体的增压或定量分配。其作用的本质的是利用齿轮旋转形成的密封腔容积变化，将机械能转化为流体的压力能和动能，从而实现流体的定向输送。
- [齿轮泵的工作原理是什么？](http://hbpumai.com/article/5666170339319711.html): 齿轮泵的工作原理核心是 “容积式吸排”—— 通过一对相互啮合的齿轮旋转，使泵体内形成周期性的密封腔容积变化，利用 “真空吸液、挤压排液” 的过程，将机械能转化为流体的压力能和动能，实现流体的定向输送。
- [齿轮泵的工作原理在实际生活中有哪些应用？](http://hbpumai.com/article/5666170705572634.html): 齿轮泵的工作原理（容积式吸排、定量高压、适应高粘度、自吸能力强）决定了它能适配生活中 “需要稳定输送流体、尤其是粘稠 / 高压场景” 的需求 —— 从日常出行的汽车，到工业生产、食品加工，甚至户外作业的工具，都能看到其原理的实际应用。
- [液压马达的工作压力和排量如何计算？](http://hbpumai.com/article/5666171433461336.html): 这两个参数的计算是液压系统选型、工况匹配的基础（如根据负载算工作压力，再选额定压力匹配的马达；根据转速和流量算排量，确保动力足够）。
