如何处理液压系统运行造成的流量损失?

发布时间:2020-01-07 14:28:43   发布人:http://www.sdjingtuo.com
  在由气液增压泵和箱体组成的液压系统中,每个测压元件都有一个相对运动的表面。例如,液压缸的内表面和活塞的外表面由于相对运动而有一定的间隙。
  In a hydraulic system composed of a gas-liquid booster pump and a box, each pressure measuring element has a relatively moving surface. For example, there is a certain clearance between the inner surface of the hydraulic cylinder and the outer surface of the piston due to relative movement.
  如果间隙的一边是高压油,另一边是低压油,那么高压油就会通过间隙流向低压区,造成泄漏。同时,由于液压元件密封不完善,部分油液也会向外泄漏。这种泄漏导致实际流量的减少,这就是我们所说的流量损失。

  If one side of the gap is high-pressure oil and the other side is low-pressure oil, the high-pressure oil will flow to the low-pressure area through the gap, causing leakage. At the same time, because the sealing of hydraulic components is not perfect, some oil will leak out. This leakage leads to the reduction of actual flow, which is what we call flow loss.
  流量损失影响运行速度,泄漏难以完全避免,因此液压系统中的额定泵流量略大于系统工作所需的流量。它也可以通过将系统工作所需的流量乘以1.1到1.3的系数来估计。
  The flow loss affects the operation speed, and the leakage is difficult to avoid completely. Therefore, the rated pump flow in the hydraulic system is slightly larger than the maximum flow required by the system. It can also be estimated by multiplying the maximum flow required for system operation by a factor of 1.1 to 1.3.
