Latest Patents

One of He Liu's latest patents is a flow control system for digital and mechanical redundant pressure compensation. This innovative system incorporates two-position three-way electromagnetic valves to manage the opening and closing of pressure compensation valves. It also features pressure sensors and a controller, enabling a digital pressure compensation function. In the event of a sensor failure, the system can switch to a mechanical compensation mode, ensuring that flow control is maintained. This design addresses the challenge of flow regulation during sensor breakdowns and achieves redundancy control. Additionally, the system allows for complete opening of the pressure compensation valve in high-load scenarios, minimizing pressure loss and maintaining stability against load fluctuations.

Another notable patent is an engineering machinery hydraulic system with controllable compensation differential pressure. This invention utilizes an electronic pressure compensating valve to address flow mismatches that occur under conditions of pressure over-limit and flow saturation. It enables proportional shunt control and high-precision flow distribution, resulting in low energy consumption, rapid response times, and enhanced flow control precision.
