What is PC Pumps Rotors
Usage: The progressive cavity pump rotor is the core component of fluid transportation, which cooperates with the stator to form a sealed cavity and pushes crude oil, mud, corrosive fluids and other media, and is widely used in oil drilling/oil production, chemical industry, and sewage treatment.
Material/geometric characteristics: materials cover stainless steel, corrosion-resistant alloys, and wear-resistant alloys; The structure is a complex spiral surface, which requires precise tolerance (≤0.01mm), and the size is suitable for workpieces with a length ≤ 700mm.
Common risks: traditional processing is prone to deformation, rough surface, and excessive accuracy; The traditional process has low efficiency (4-6h/set) and poor consistency (defect rate of 15%), making it difficult to meet the needs of mass production.

PC Pumps Rotors Whirling Process
Complete machining link: blank preparation→ roughing→ cyclone milling finishing (core link: PH50-1000), surface treatment→ quality inspection →
PH50-1000 is the core link, which realizes high-precision machining of spiral surfaces through four-axis linkage cyclone milling, which directly determines product accuracy and efficiency. All links are closely connected: blanks need to be tested for materials, roughing provides basic dimensions for cyclone milling, surface treatment optimizes finish, and quality inspection ensures compliance with standards.
(1) Blank preparation
- Specific method: Choose the alloy material (such as corrosion-resistant alloy for petroleum) + forging/casting according to the application scenario
- Parameters: None
- Risk and control: Uneven material → detected with a spectrum analyzer
- Equipment: Spectrum analyzer
(2) Rough machining - How: Turn the outer circle/face to the base size
- Parameters: rotation speed 500-800rpm, feed 0.2mm/r
- Risk and control: deformation of the workpiece → proper clamping (three-jaw chuck)
- Equipment: Ordinary lathe
(3) Cyclone Milling Finishing (Core) - Specific method: Four-axis synchronous cyclone milling spiral surface
- Parameters: Rotation speed 1000-1500rpm, feed 0.1mm/r
- Risk and control: surface burns→ high-pressure cooling + frequency conversion speed regulation
- Equipment: PH50-1000 CNC cyclone milling machine
(4) Surface treatment - Specific method: automatic polishing/plating (depending on the application scenario)
- Parameters: None
- Risk and Control: Loss of finish→ Precision polishing machine
- Equipment: Precision polishing machine
(5) Quality inspection - Specific method: dimensional measurement + surface finish inspection
- Parameters: None
- Risk and control: missed detection →coordinates
- Equipment: CMM
