Hydraulic Closed-Center Circuit with Load Sensing

Load sensing is achieved with a special compensator mounted on a variable displacement pressure-compensated pump. The reader should envision this special compensator mounted on the pump shown in Fig. 4.15. For this analysis, we assume that the special compensator is … Continue reading

Open-Center Hydraulic Circuit

The fixed displacement pump shown in Fig. 4.3 delivers 20 GPM continuously. The relief valve is set on 2500 psi. When the DCV is manually shifted, the pump builds pressure to 1300 psi, and the load begins to move. At … Continue reading

Hydraulic Load Sensing Efficiency Improvement

Load sensing was developed to improve the efficiency of a circuit. It requires a variable displacement pump; thus, it is appropriate to discuss it here. An example will illustrate the advantage provided by load sensing. An application requires a maximum … Continue reading
