Hydraulic power calculation formula: W = PQ/(612*0.85)
Pressure P refers to the pressure of the hydraulic system, Q refers to the product of the displacement of the pump and the extra speed of electricity, the motor power calculated by the product of the system practice pressure and flow and a power can be used as the driving power of the pump, the pump displacement X motor practice speed, the displacement is the amount of oil produced by the pump at one rotation.
P refers to the high pressure of the pump port, Q refers to the large displacement of the pump; The pressure of the pump should be pushed down from the working pressure of the performance components, including the pressure drop of various valves, mainly servo valves and proportional valves, thinking about the pipeline pressure drop; Pay attention to the first choice of motor after pump, motor usually choose four pole Y-3 series (because the extra flow of the pump is usually measured at 1500 RPM, and four pole motor speed also happens to be around here), motor type to think about mechanical power and power elements. After the motor is selected, the pump can be selected.
