In the petrochemical industry, screw pump rotors have various application scenarios. For example, in the petroleum refining process, screw pumps are often used to achieve vacuum distillation and degassing operations, reducing system pressure and improving product quality through efficient pumping capabilities.
In addition, during chemical reactions, screw pumps can be used for vacuum drying and desolvation operations to improve reaction efficiency. In the production of polymer materials, screw pumps are used for vacuum extraction and extrusion operations to ensure the safety and efficiency of the production process.
9 Steps Get Screw Pump Rotors For The Petroleum Industry Use Whirling Machine
Using cyclone milling to process screw pump rotors in the petroleum industry can be done by following the following steps:
1.Design and planning
- Carry out detailed design and process planning according to the specific specifications and requirements of the screw pump rotor. Determine the size of the rotor, helix parameters (such as lead, helix angle, etc.) and machining accuracy requirements.
- Select the appropriate cyclone milling tool and tool holder system to ensure that the material and geometry of the tool are suitable for the material and processing requirements of the screw pump rotor in the petroleum industry. Generally speaking, for materials with higher hardness, carbide cutting tools can be chosen.
2.Equipment inspection and debugging
- Check whether all functions of the tornado milling machine are normal, including spindle rotation, tool feed, cooling system, etc. Ensure that the accuracy and stability of the machine tool meet processing requirements.
- Install and debug the cutting tool to ensure that the cutting tool is firmly installed and has good concentricity with the machine tool spindle. Adjust the protrusion length and angle of the tool to match the parameters of the rotor to be processed.
3.Artifact preparation:
- Prepare the screw pump rotor blank to be processed. Ensure that the size and quality of the blank meet the requirements and that there are no obvious defects on the surface.
- Install the rotor blank on the chuck or fixture of the whirling machine tool, ensuring that the installation is firm and the positioning is accurate. Special fixtures can be used to ensure the stability and accuracy of the rotor during processing.
4.Parameter settings
- According to the material, size and processing requirements of the rotor, set appropriate cutting parameters, including cutting speed, feed speed, cutting depth, etc. Generally speaking, for materials with higher hardness, the cutting speed should be appropriately reduced to reduce tool wear; the feed speed and cutting depth should be reasonably adjusted according to processing efficiency and accuracy requirements.
- Set the helix angle and rotation direction of the cyclone milling machine to match the helix parameters of the screw pump rotor. Ensure that the tool can cut along the correct spiral path during machining.
5.roughing
- Start the tornado milling machine for rough machining. In the roughing stage, the main purpose is to quickly remove most of the allowance and improve processing efficiency. Larger cutting depth and feed speed can be used, but care should be taken to control the cutting force to avoid tool damage or workpiece deformation.
- Regularly check the tool wear during processing and replace seriously worn tools in a timely manner to ensure processing quality and efficiency.
6.Finishing
- After rough machining is completed, finish machining is performed. Reduce the cutting depth and feed speed, and increase the cutting speed to obtain higher machining accuracy and surface quality.
- Pay attention to controlling the temperature during processing to avoid excessive temperature deformation of the workpiece or increased tool wear. A cooling system can be used to cool the tool and workpiece and reduce the processing temperature.
7.Quality Check
- After processing is completed, the screw pump rotor is inspected for quality. Mainly check whether dimensional accuracy, surface roughness, spiral shape, etc. meet the design requirements. Measuring equipment such as measuring tools and profilometers can be used for measurement.
- For parts that do not meet the requirements, appropriate trimming or reprocessing will be carried out until the quality requirements are met.
8.Surface Treatment
According to the special requirements of the petroleum industry, the screw pump rotor is subjected to surface treatment, such as coating, anti-corrosion treatment, etc., to improve the wear resistance, corrosion resistance and fatigue resistance of the rotor.
9.Cleaning And Packaging:
- Clean the processed screw pump rotor to remove oil stains, chips and other impurities on the surface. Cleaning agents and compressed air can be used.
- Pack the rotor with appropriate protective measures to prevent damage during transportation and storage.
In short, the use of cyclone milling to process screw pump rotors in the petroleum industry requires sufficient preparation, reasonable setting of processing parameters, strict control of quality during processing, and appropriate follow-up processing to ensure that the processed rotors meet the high requirements of the petroleum industry.
