What is the size of the hydraulic system?
The flow of the hydraulic system mainly depends on the speed of actuator, speed depends on the flow, when the components of the form and size of certain can according to the required speed to calculate the required flow, for the required pump displacement, should consider to overflow and leakage, in according to certain coefficient multiplied by the calculated flow provided instant required pump flow
The function of the hydraulic system is to increase the force of pressure by changing the pressure. A complete hydraulic system consists of five parts: the power component, the execution component, the control element, the auxiliary component (the attachment) and the hydraulic oil. Hydraulic system can be divided into two kinds: hydraulic drive system and hydraulic control system. The hydraulic transmission system is the main function of transmission and motion. Hydraulic control system to make the hydraulic system output to meet specific performance requirements (especially dynamic performance), usually called the hydraulic system is mainly refers to the hydraulic transmission system.
For pump flow, generally refers to the volume of discharged liquid pump in unit time and commonly used units for L/min, the theory of flow = x discharge pump rotor speed, flow depends on the pump displacement and rotating speed. Again and again, for the variable pump, if the power is constant, due to the stress theory of hydraulic pump power = x flow, is under the power balance, if speed is changeless, the pump flow rate is inversely proportional to the pump outlet pressure. For the flow in the hydraulic system, the unit time usually refers to the volume of the liquid in the unit, which is still the same as L/min. For the flow of the system, there are more factors, such as the output flow of the power component, the size of the pipe, the size of the valve, and so on.
