The following factors need to be considered when selecting micro hydraulic components:
Functional requirements: Clarify the type of action and action coordination requirements that the system needs to perform. For example, hydraulic cylinders are preferred for linear motion (such as lifting, pushing and pulling), and the stroke, speed and thrust need to be determined; hydraulic motors are selected for rotary motion (such as stirring, walking), and the speed and torque need to be matched.
Control method: Select the appropriate control method according to the application scenario. Manual control is suitable for temporary or low-frequency operations, electronic control (such as PLC) is suitable for complex actions, and proportional/servo control is suitable for high-precision scenarios.
Performance indicators: Ensure that the system can operate efficiently. Pressure and flow need to be calculated based on the load, and a safety margin should be left; the selection of pumps needs to consider efficiency and heat control. Variable pumps are suitable for continuous work, and fixed-flow pumps are suitable for intermittent work.
Selection of hydraulic pumps: The specifications and models of hydraulic pumps need to be selected based on the calculated values. Usually, the rated pressure of the pump should be 25%-60% higher than the working pressure, and the rated flow should be close to the demand to avoid power loss.
Other hydraulic components selection: including flow valves, relief valves, check valves and hydraulic control check valves. When selecting, you need to consider parameters such as the minimum stable flow, opening pressure and control performance.
Oil selection: Choose the appropriate hydraulic oil according to the working environment. For example, YA-N46 hydraulic oil can be used in the south, YA-N68 hydraulic oil is recommended in the north, and YA-N32 hydraulic oil is used in cold areas.
