Machinery loss of mechanical loss refers to the loss of hydraulic torque. It is equal to the hydraulic pump of large theoretical torque Tt and the actual ratio of the input torque T, the torque loss is provided a hydraulic motor repair Tl, the mechanical efficiency of the hydraulic pump (2) The power of the hydraulic pump 1) Input power refers to power input acting on the pump shaft mechanical power hydraulic motor, when the input torque Ti hydraulic motor repair, when the angular velocity = ω Tiω2) output power P refers to hydraulic output power during operation of the actual suction pressure between ports differential pressure Δp and output flow q product, namely P = Δpq (3) the overall efficiency of the overall efficiency of the hydraulic pump is the ratio of actual output to its input power of qualitative and quantitative analysis should be unified and mutually reinforcing; Qualitative analysis is the basic prerequisite for quantitative analysis, qualitative and quantitative is not a blind, worthless quantitative; qualitative and quantitative analysis to make it more scientific and accurate, it can cause extensive and in-depth qualitative analysis of the conclusions drawn. Quantitative analysis is based on statistical data, the mathematical model and a mathematical model to calculate the object's method of analysis of the indicators and their values.
