Parker Hydraulic Pumps Causes of Mechanical Loss
When Parker Hydraulic Pumps are working, there is mechanical friction between the relative moving parts, such as between the bearing and the shaft, between the shaft and the seal, between the blade and the inner wall of the pump, resulting in loss of frictional resistance.
①. When Parker Hydraulic Pumps are working, there is mechanical friction between the relative moving parts, such as between the bearing and the shaft, between the shaft and the seal, between the blade and the inner wall of the pump, resulting in loss of frictional resistance. This loss is related to the output pressure of Parker Hydraulic Pumps, the higher the output pressure, the greater the loss of frictional resistance.
②. When the oil flows in the pump, viscous resistance will be generated due to the viscosity of the liquid, which will also cause mechanical loss. This loss is related to the viscosity of the oil and the speed of the pump. The more viscous the oil and the higher the speed of the pump, the greater the mechanical loss.
Due to the above reasons, the actual input power of the pump is greater than the theoretically required power. The ratio of theoretical input power to actual input power of Parker Hydraulic Pumps is called mechanical efficiency, which indicates the degree of power loss. The ratio of the output power of Parker Hydraulic Pumps to the input power is called the total efficiency of Parker Hydraulic Pumps.
