Hydraulic Pressure vs. Flow: Understanding the Difference

The pump doesn’t pump pressure. The pump delivers a rate of flow. The single function of the pump is to take fluid from one place and put it somewhere else. Pressure is the result of resistance to flow. In our training classes, we use the simple schematic shown above to …

Line Sizing And Fluid Velocity In Hydraulic Systems

Return: 10-15 feet/sec. Medium Pressure: 15-20 feet/sec. High Pressure: 20-25 feet/sec. On extremely long lines the pressure drop through the pressure and return lines must be accounted for to insure sufficient pressure is available at the actuator. (See pressure drop charts included with this document).

Gates Hydraulics 101

Hydraulic Valves- control pressure, direction and flow rate of the hydraulic fluid. Actuator - converts hydraulic energy into mechanical energy to do work. An actuator can be a rotary hydraulic motor or a hydraulic cylinder. Hydraulic motors and cylinders are used on agricultural, construction and industrial equipment.


The flow capacity normogram is an aid to determine the correct hose internal diameter size, desired flow rate and recommended velocity. By the use of any two known factors, the third can be determined. 1.2 Pressure After determining the system pressure for a hydraulic system, hose selection must be made so that the recommended

Troubleshoot Hot Hydraulics - Efficient Plant

8/7/2015· “This case-drain flow,” noted Smiley, “does no useful work and is, therefore, converted into heat.” According to Smiley, the normal flow rate out of the case-drain line is 1% to 3% of the maximum pump volume. For example, a 30-gpm pump should have approximately 0.3 to 0.9 gpm of oil returning to the tank through the case drain.

Solving Hydraulic System Overheating Problems

For example, if the measured temperature drop across the exchanger is 4ºC and the design oil flow-rate is 90 L/min, the exchanger is dissipating 10 kW of heat. Relating this to a system with a continuous input power of 100 kW, the exchanger is dissipating 10 percent of input power.
