8results about How to "Flow is easy to control" patented technology

This invention relates to the field of bulldozer technology and provides a hydraulic control system and method for bulldozers. It recovers the energy generated by the descent of the bulldozer's working device through an accumulator. When the working device is lifted or other mechanisms require hydraulic pressure, a solenoid valve is opened. A solenoid proportional valve opens its valve core according to the compensation flow required by the second inlet valve. The oil in the accumulator provides a corresponding flow rate according to the opening degree of the solenoid proportional valve. The solenoid proportional valve sends the hydraulic oil from the accumulator through a first check valve to the inlet of the second inlet valve. The solenoid valve receives a compensation signal and opens the oil outlet passage of the accumulator. The hydraulic energy stored in the accumulator, after being regulated by the control terminal of the solenoid proportional valve, is then delivered through the first check valve to the inlet of the second inlet valve and subsequently enters the lifting chamber of the lifting cylinder. This compensates for the lifting of the blade, achieving stable and controllable oil flow and ensuring smooth movement of the working device or other actuators.
