Define Phase

Marketing and production considerations determine the acceptable range of flow rates based on how many units should be produced daily to meet market demand, what is useful production time per day based on plant setup and productivity, and how many pumps are placed in each plant.

The food processing company translates marketing requirements into these engineering specifications and provides them to you:

Based on these requirements, you propose a displacement pump with a reciprocating piston. Figure 174, The jar-filling system with displacement pump, following, shows a basic schematic of the system.

Figure 174. The jar-filling system with displacement pump

This figure displays the flow of a displacement pump from the reservoir, through the inflow into the piston, which is pushed by the motor and outflow to the jars. A backflow valve is in place on the tube from the reservoir. This figure displays a basic schematic of the system. The flow goes from the reservoir, through the inflow into the reciprocating piston. The flow continues into the outflow to the jars. A backflow valve is in place on the tube from the reservoir.
