Some Causes and Effects of Pressure Pulsation in a Hydraulic System Including the Impact on the Environment

A theoretical analysis of displacement pump capacity pulsation was carried out. In a hydraulic system, capacity pulsation contributes to pressure pulsation. It has been pointed out that increased pressure pulsation affects the surroundings, including human beings, causing an increase in the noise generated into the surroundings and increasing vibration levels. The values of the frequencies of the pressure pulsation thus created correspond to the frequencies of the capacity pulsation and are derived from the number of displacement elements in the pump and the speed on its drive shaft. A complex univariate was used to determine the frequency characteristics of the system with a hydraulic long line by subsequently determining the transmittance of the system.
