Calculation of inlet pressure of the pump

Click For Summary
SUMMARY

The discussion focuses on calculating the inlet pressure of a piston pump operating at 400 bar. The pump has an inlet port diameter of 7mm and an outlet port diameter of 2.8mm. The primary concern is determining the vacuum pressure at the inlet, which is influenced by the force exerted on the piston. The conversation suggests that further insights may be found in the General Engineering subforum.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with piston pump mechanics
  • Knowledge of pressure measurement units, specifically bar
  • Basic skills in engineering calculations
NEXT STEPS
  • Research the principles of vacuum pressure in piston pumps
  • Learn about pressure loss calculations in fluid systems
  • Explore the effects of inlet and outlet diameters on pump performance
  • Investigate advanced topics in fluid dynamics relevant to pump design
USEFUL FOR

Mechanical engineers, fluid dynamics specialists, and anyone involved in pump design and performance optimization will benefit from this discussion.

hello guys,
i wanted to calculate inlet pressure of the pump( vacuum pressure). pump operates at 400 bar.
pump works by sucking the grease from the inlet port of dia 7mm and delivers it through outlet port of dia 2.8mm. pump used here is piston pump. the force acting on the piston is 400bar.

regards
Ashwin
