What are the key design points for pipeline design in fluid power transmission systems in instrument manufacturing to ensure stable fluid conveyanceг┐

Fluid power transmission systems play a crucial role in industrial production, especially in applications involving precise control and stable fluid conveyance, such as chemicals, pharmaceuticals, food processing, etc. In the design and manufacturing of fluid power transmission systems, pipeline design is a key link to ensure stable fluid conveyance. The following are several important design points:

1. Pipeline material selection

Corrosion resistance: Select appropriate materials based on the properties of the fluid, such as stainless steel, copper, plastics, etc., to prevent material corrosion or erosion by the fluid.

Fluid compatibility: Select materials that are compatible with the fluid to avoid chemical reactions between the material and the fluid, which may lead to pipeline damage or fluid contamination.

2. Pipeline diameter and length

　　Flow rate: Select an appropriate flow rate based on the viscosity of the fluid and the required conveyance volume. Excessive flow ratemay cause pressure fluctuations and fluid impact.

Length and elbows: Minimize the length of the pipeline and reduce the number of elbows to reduce fluid resistance and pressure loss. If bending is necessary, the design should be made with the smallest bending radius to reduce fluid vortices and turbulence.

3. Pipeline connections

　　Sealability: Ensure that all connection points have good sealing to prevent fluid leakage.

Fasteners: Use appropriate fasteners and threaded connections to ensure firm connections while facilitating disassembly and maintenance.

4. Fluid pressure and temperature control

Pressure vessel: For fluids under high pressure, the design needs to consider the use of pressure vessels or reinforced pipeline structures to ensure safety.

Temperature control: Considering the changes in the physical properties of fluids at different temperatures, such as viscosity and density, select appropriate pipeline materials and insulation measures to ensure stability and efficiency during fluid conveyance.

5. Safety and protection measures

Pressure monitoring: Install pressure monitoring equipment to monitor the pressure inside the pipeline in real time, to prevent excessive or low pressure.

Safety valve: Install a safety valve to automatically open and release pressure when the system pressure exceeds the set value, to prevent overloading of the system.

Conclusion

The design and manufacturing of fluid power transmission systems require comprehensive consideration of various factors to ensure stable and safe conveyance of fluids. Through careful design and selection of appropriate materials and equipment, the reliability and efficiency of the system can be significantly improved.
