In biogas engineering, the raw materials come from a wide range of sources, mainly energy crop stalks, grass, cereals, animal manure, rubbish etc. They are mixed with various particles of larger debris, such as chicken feathers in chicken manure, long grass and gravel in cow manure etc. The lobe pump conveys smoothly, with low pulsation, low shear force and good passability just suitable for conveying raw materials in biogas projects.
Advantages of lobe pumps in biogas engineering.
1, when the lobe pump conveys the medium, the medium is filled in the closed cavity formed by the rotor and the pump casing and discharged with the movement of the cavity, therefore, the lobe pump is most suitable for conveying such media as biogas raw materials which have high particle content and large particle diameter.
2. The lobe pump has two elastomeric contact lobe rotors, and the rotors are available in a variety of materials and configurations that are both wear-resistant and adaptable.
3, the lobe pump also has the advantages of online maintenance, compact structure, small footprint, few wearing parts (only a pair of rotor and mechanical seal), long life of wearing parts, etc..
4, the lobe pump is a highly efficient volumetric pump, under the same working conditions, its starting torque and running torque are lower than the single screw pump, from the point of view of energy saving, the rotary lobe pump is the first choice for raw material transfer.
