Applications of Oil Pump Rotor
BLUE’s oil pump rotors have been applied in Weichai, Cummins, Honda, Toyota, and many other engines.
When these vehicles are driving at high speeds, the engines run violently and need lubricating oil protection. Therefore, the oil pump rotor is indispensable.
In addition, some mechanical equipment also needs lubricating oil to protect the engine. The oil pump rotor pumps out lubricating oil to ensure the smooth operation of the equipment.
How Oil Pump Rotor Works?
The oil pump rotor consists of an inner rotor and an outer rotor, which are driven to rotate by the transmission device on the crankshaft.
As the inner and outer rotors rotate, multiple working chambers are formed between them, with their volumes constantly changing. On the oil inlet side, the chambers expand, creating a vacuum that draws in oil. The rotors then carry the oil to the outlet side, where the chambers contract as the rotors mesh, increasing pressure and pushing the oil out.
The inner rotor and the outer rotor need to be matched, and the radial clearance during assembly is usually 0.08-0.13 mm. In addition, the oil pump rotor requires high-strength and wear-resistant materials to ensure service life.
Mechanical Properties of Oil Pump Rotors Materials
Here are some common mechanical properties of oil pump rotors materials. The inner rotor typically uses FN-0208-30, while the outer rotor uses FL-4205-45. Free to ask our team if you have any questions about materials.
| Model | Density | Tensile Strength | Hardness |
|---|---|---|---|
| FN-0208-30 | 6.70 g/cm3 | 310 Mpa | 63 HRB |
| FL-4205-45 | 7.10 g/cm3 | 460 Mpa | 70 HRB |
| FC-0208-50 | 6.70 g/cm3 | 410 Mpa | 73 HRB |
| FD-0205-50 | 6.95 g/cm3 | 540 Mpa | 76 HRB |
| FD-0208-55 | 6.90 g/cm3 | 540 Mpa | 83 HRB |
| FD-0405-60 | 7.05 g/cm3 | 710 Mpa | 85 HRB |

Oil Pump Rotors Manufacturing Process
Powder metallurgy is a precision manufacturing process with a continuing and stable accuracy of up to 0.01mm, which requires strict control at each stage to ensure the quality of the final part. Any deviation or error during the process may result in the rejection of the entire batch.
Designing
Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.
Tooling
Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.
Mixing
Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.
Compacting
Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.
Sintering
Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.
Sizing
Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.
Tumbling
Tumbling removes burrs and flash from a part's surface by vibrating it with abrasive media, such as stone or ceramic, resulting in a smoother finish.
Machining
Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.
Blackening
Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.
Hardening
Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.
Inspecting
The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.
Packaging
BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.
