Working principle of hydraulic pump: the movement brings about the change of pump chamber volume, so as to compress the fluid and make the fluid have pressure energy. The necessary condition is that the pump chamber has the change of sealing volume.
Hydraulic pump is a kind of hydraulic component that provides pressurized liquid for hydraulic transmission. Its function is to convert the mechanical energy of power machine (such as motor and internal combustion engine) into the pressure energy of liquid. The working principle of the single plunger pump is that the cam is driven by the motor to rotate. When the cam pushes the plunger upward, the sealing volume formed by the plunger and the cylinder block decreases, and the oil is squeezed out of the sealing volume and discharged to the required place through the one-way valve. When the cam rotates to the lower part of the curve, the spring forces the plunger downward to form a certain vacuum, and the oil in the tank enters the sealing volume under the action of atmospheric pressure. The cam makes the plunger continuously rise and fall, the sealing volume decreases and increases periodically, and the pump continuously absorbs and discharges oil.

液压泵的工作原理：运动带来泵腔容积的变化，从而压缩流体使流体具有压力能，必须具备的条件就是泵腔有密封容积变化。
液压泵是为液压传动提供加压液体的一种液压元件，是泵的一种。它的功能是把动力机(如电动机和内燃机等)的机械能转换成液体的压力能。单柱塞泵的工作原理是凸轮由电动机带动旋转,当凸轮推动柱塞向上运动时，柱塞和缸体形成的密封体积减小，油液从密封体积中挤出，经单向阀排到需要的地方去。当凸轮旋转至曲线的下降 部位时，弹簧迫使柱塞向 下，形成一定真空度，油 箱中的油液在大气压力的 作用下进入密封容积。凸轮使柱塞不断地升降，密封容积周期性地减小和增 大，泵就不断吸油和排油。
