Table 1: OPTIA.DAT file of input parameters for identifying the duty cycle. Increased pressure pulsations can lead to higher leakage rates, reducing overall efficiency. Variations in pressure can increase friction between moving parts, leading to energy losses. Higher pulsations can cause more heat generation, requiring additional cooling and thus more energy. Energy is wasted in compensating for the pressure fluctuations rather than performing useful work. Pressure pulsations cause the power output to fluctuate, affecting the stability and control of the hydraulic system. These fluctuations can lead to vibrations and mechanical stress on the system components, potentially reducing the lifespan of the system. Inconsistent power delivery can impact the performance of machinery, leading to inefficiencies in operations that rely on precise and stable power output.
