hydraulic system design how to reduce the power loss

Power loss of the hydraulic system on the one hand will cause the loss of energy, the overall efficiency of the system decreased, on the other hand, this part of the lost energy will be transformed into heat, so that the hydraulic oil temperature, oil deteriorati on, resulting in hydraulic equipment failure. Therefore, the design of hydraulic systems, to meet the requirements under the premise, but also give full consideration to reduce system power loss. Let us from the following aspects to explain in detail:hydraulic hose adapters

First, from the power source - pump to consider, taking into account the diversification of the actuator working conditions, sometimes the system needs a high flow, low pressure; sometimes need a small flow and high pressure. So I chose to limit the pressure variable displacement pump is appropriate, because this type of pump flow varies with the change of system pressure. When the system pressure is reduced, the flow is relatively large, to meet the rapid stroke of the actuator. When the system pressure increases flow rate is reduced accordingly, able to meet the working stroke of the actuator. This meets the requirements of the actuator, but al so make the power consumption is quite reasonable.hydraulic flanges

Secondly, if the actuator has a speed control requirements, then choose the speed control loop, it is necessary to meet the requirements of the governor, but also to minimize power loss. Common speed control loop: the throttle speed control loop, the volume speed control loop Volume Throttling governor loop. Throttle speed control circuit power loss, low-speed stability is good. Neither overflow losses and volume speed control loop, there is no throttling losses, high efficiency, but low-speed stability. If you want to meet both requirements, the volume of the differential pressure variable displacement pump, and throttle throttle speed control loop can be used, and the throttle at both ends of the pressure difference as small as possible, in order to reduce the pressure loss.

Third, the hydraulic oil flows through the various type s of hydraulic valves, the inevitable existence of pressure losses and flow losses, this part of the energy loss in a large proportion of total energy loss. Therefore, a reasonable choice of hydraulic, adjust the pressure valve, pressure is also an important aspect of reducing power losses. The flow control valve according to the system flow rate adjustment range to select and to ensure that its minimum stable flow can meet the requirements, the pressure valve of the pressure to meet the normal work of the hydraulic equipment, try to take a lower pressure.hydraulic fittings

Fourth, a reasonable choice of hydraulic oil. Hydraulic oil flow in the pipeline, will appear in the viscosity, the viscosity is too high, will have a larger internal friction, causing the oil fever, while increasing the resistance of the oil flow. When the viscosity is too low, it could easily lead to the leakage will reduce the efficiency of the system volume, therefore, generally select the appropriate viscosity and viscosity-temperature characteristics of a good oil. In addition, when the fluid flow in the pipeline, along the pressure loss and the local pressure loss, and try to shorten the pipeline design pipeline, while reducing elbow.
