Screw pump rotors fabrication method
It is used for the manufacture of screw pump rotors for the food and chemical industries' equipment, pieces of propeller ICE, and drilling equipment.
Advantages
- ensuring high accuracy in the processing of workpieces with an uneven allowance by controlling the dynamics of the process of cutting and elastic strains of the components of the processing system
- increase in turning efficiency by 2-3 times due to intensification of the cutting modes
- the possibility of using universal machine tools
Features
The technology is based on the primary forming of channel helix with independent control of the profile runout, form, and spacing of the helix. This makes it possible to process a wide range of screw rotors on one machine.
A set of equipment for the implementation of the technology
- upgraded turning and relieving lathe
- rotor profiling cams
- special cutters
Performance
Dimensions of processed products:
- diameter up to 200 mm
- length up to 1000 mm
- profile runout up to 15 mm
Application
A machine for processing rotors was created on the basis of the universal turning and relieving machine tool. The production of screw pump rotors was set according to the orders of enterprises of the Republic of Belarus, which made it possible to abandon their import.
Suggestions
- manufacturing of screw pump rotors of various sizes and debugging of specific products processing technology in the field
- development of the engineering documentation for the implementation of the universal method for obtaining cylindrical surfaces with complex cross profiles
- scientific and industrial cooperation in the creation of special machines for processing complex-profile parts
