Три основни метода за контрол на хидравличния клирънс в аксиални бутални помпи

In axial piston pumps, hydraulic clearance is a problem that requires special attention. When the flow direction or load conditions change, unexpected clearance or movement may occur between pump components, which may cause system efficiency to decrease, vibration to increase, or even damage. Therefore, controlling hydraulic clearance is essential to maintain smooth operation and precise control of the pump. Here are Някои общи методи за контрол на хидравличния клирънс:
Preload mechanism: Preload mechanism eliminates or reduces clearance by applying a preload force on the pump components. This can involve the use of springs, hydraulic accumulators, or mechanical elements to generate a constant force to keep the components engaged. By eliminating free clearance, clearance is minimized, thereby improving control and reducing вибрация .
Алгоритъм за контрол: Разширените алгоритми за контрол могат активно да компенсират хидравличния клирънс . Тези алгоритми компенсират клирънс, като наблюдават съответно работни условия на помпата, включително поток, налягане и натоварване и регулиране на контролния сигнал съответно . чрез непрекъснато регулиране Точност .
Feedback control: Feedback control systems measure the actual position or pressure of pump components by incorporating position or pressure sensors into the pump system and compare it with the expected value. The feedback signal is then used to adjust the control input, compensating for any detected backlash and maintaining desired performance.
