First of all, working pressure is one of the key factors in determining the selection of non-standard hydraulic station components. The working pressure of non-standard hydraulic station must meet the workload requirements of the machine tool or equipment actuator. For example, for a machine tool that requires strong cutting, its hydraulic clamp may require a higher pressure to firmly clamp the workpiece to prevent the workpiece from shifting during processing. Therefore, when selecting components such as hydraulic pumps and pressure valves, it is necessary to ensure that their rated pressure can meet or exceed the system's working pressure requirements.
Secondly, flow requirements are also an important basis for selection. The flow determines the movement speed of the actuator and the total flow requirements when multiple actuators in the system work simultaneously. When selecting components such as oil pumps and flow control valves, they need to be matched according to the system's flow requirements to ensure that the actuator can move at the expected speed.
The temperature environment also has an important impact on the selection of non-standard hydraulic station components. In a high temperature environment, the viscosity of the hydraulic oil decreases, which may lead to increased leakage. Therefore, it is necessary to select hydraulic oil with good high temperature stability, and the hydraulic station should be equipped with effective heat dissipation measures. In low temperature environment, the viscosity of hydraulic oil increases, which may affect the startup and response speed of the system. At this time, it may be necessary to preheat the hydraulic oil or select hydraulic oil with good low temperature performance.
In addition, space limitations are also factors that need to be considered when selecting. Due to its customized characteristics, non-standard hydraulic stations may have special requirements for installation space. When selecting, it is necessary to consider whether the size and shape of the hydraulic station can adapt to the layout of the machine tool or equipment.
Cleanliness and protection requirements are also important bases for the selection of key components. For some high-precision non-standard machine tools, the cleanliness requirements of hydraulic oil are higher, and high-precision filters may be required. At the same time, non-standard hydraulic stations need to have good sealing performance to prevent impurities from entering the hydraulic system and accelerating the wear of components.
Motor power matching is also the key to selection. Calculate the motor power according to the working pressure and flow of the hydraulic station to ensure that the motor can provide sufficient driving force.
Finally, the selection of oil pump type also needs to be based on the specific needs of the system. Common oil pumps include gear pumps, vane pumps and plunger pumps. Different types of oil pumps are suitable for different working pressures and flow ranges.
