The primary function of the electromagnetic proportional pressure relief valve in an excavator is to control the flow and pressure of the hydraulic system, as well as to regulate the engine’s speed and load.

The hydraulic system of an excavator is a complex system in which the electromagnetic proportional pressure relief valve plays a crucial role. It achieves precise control of various actions of the excavator by managing the flow and direction of hydraulic fluid. Specifically, the functions of the electromagnetic proportional pressure relief valve include:

– Flow and Pressure Control: The valve can automatically adjust the flow and pressure of the hydraulic system based on changes in the working load, ensuring that the excavator operates efficiently and stably under different working conditions.

– Adaptation to Complex Working Conditions: During operation, excavators face diverse and complex conditions. The electromagnetic proportional pressure relief valve receives various signals through an electronic controller, such as the selected power mode, engine speed gear, and actual speed. It analyzes these signals and sends pulse signals to the electro-hydraulic proportional pressure relief valve, allowing it to adapt to various complex working conditions and avoiding frequent oscillation of the working pump’s swash plate.

– Engine Protection: By precisely controlling the flow and pressure of the hydraulic system, the electromagnetic proportional pressure relief valve helps protect the engine from operating under high load or low efficiency conditions, thereby extending the engine’s lifespan.

– Improving Work Efficiency: By optimizing the performance of the hydraulic system, the electromagnetic proportional pressure relief valve enhances the overall work efficiency of the excavator, allowing it to perform at its best in various working scenarios.

In summary, the electromagnetic proportional pressure relief valve in an excavator ensures efficient and stable operation by precisely controlling the flow and pressure of the hydraulic system and regulating the engine’s speed and load. It also protects the engine from damage and improves work efficiency.
