本文提出一种采用泄漏补偿原理实现电液比例泵恒流量调节的新方法,避免了传统的恒流调节泵因在主油路上直接检测负载流量所带来的附加的全流量节流功率损失。试验表明,补偿后的恒流量泵的稳态和动态特性均达到或超过传统的采用流量反馈的恒流量泵。
In this paper, a new method of compensating the constant flow of the electro-hydraulic proportional pump by using the principle of leakage compensation is proposed, which avoids the additional full-flow throttling power loss caused by the direct detection of the load flow on the main oil passage by the conventional constant-flow regulating pump. The experimental results show that the steady-state and dynamic characteristics of compensated constant flow pump meet or exceed the traditional constant flow pump that uses flow feedback.
