Project Description

Assignments

  • The client’s objective¬†was to reduce the number of defects on a paste mixing unit.

  • When emptying the mixer, the operator often forgot to turn off the pump, which resulted in a defective pump housing.

  • Multiple types of products with different viscosities caused different pressures in the teflon pipe when the product was pumped. This caused breaks in the teflon pipe.

Solutions

  • Intentus Engineering was selected to provide the mechanical, electrical and software engineering for this project.

  • A frequency inverter was installed to regulate the pump based on the value of a new pressure sensor in the teflon pipe.

  • The system’s load cells were programmed by Intentus Engineering, creating an output when the paste mixer was nearly empty. The output is connected to a relay that provides an input signal to the frequency inverter, stopping the pump. A push button next to the paste mixer overrides the output of the load cells and starts the pump to empty the last liters of product under the supervision of the operator.

Results

  • No more defects in the pump housing.

  • No more burst pipes.

  • Dramatic increase in capacity by reducing the number of defects

About the project

The paste mixing unit was used to mix a variety of products.
After mixing, the product was pumped through a teflon pipe that was placed in a metal detector.
