Problem Statement
- In the present era, a centrifugal pump is a common example of non-positive displacement pump, & mainly used for low pressure and high-volume flow application however having issues related to not capable of achieving high pressure, therefore said pumps cannot be used in fluid power Industries.
- Further, the positive displacement pumps are more complex and difficult to maintain than centrifugal pumps. Positive displacement pumps are less able to handle low viscosity fluids than centrifugal pumps.
- Hence, there is a need to address the above issues in efficient manner.
Technology
- The present invention describes a Positive displacement pump and a method of fabricating a positive displacement pump. (Refer Fig.1)
- Said positive displacement pump comprising a housing characterized in that the housing comprises an auxetic structure of a predefined dimension and a driving unit configured to compress and decompress the auxetic structure, thereby resulting in pumping of the fluid.
- Said auxetic structure material comprises hyperelastic material comprising at least one of thermoplastic polyurethane or rubber.
- In addition to this, said driving unit comprises a motor, a crank and a load plate.
- Further said method comprising a few steps mentioned hereunder:
- Providing a housing comprises of an auxetic structure and a driving unit;
- Compressing the auxetic structure by the driving unit in a lateral direction, resulting in Fluid flow into the housing via at least one inlet port; and
- Decompressing the auxetic structure to discharge the fluid out of the housing via outlet port;
- thereby resulting in pumping of the fluid.
Key Features/ Value Proposition
Technical Perspective:
- Claimed Patented technology provides an auxetic structure for pumping fluid.
- Further provides a pump for transfer of fluid with low, medium, and high viscosity.
- Simple design, and less rotating and reciprocating parts.
- The flowrate changes with change in design parameters of the auxetic structure, possible to control the flow rate from milliliter/min to liter/min.
- The material used in fabrication of auxetic structure is thermoplastic polyurethane (TPU), which is chemically inactive.
- Provides suitable reactive chemical transfer.
Industrial Perspective:
- Provide fabrication of a cost-effective pump for larger range of pressure and flowrate.
