Heavy-Duty Hydraulic Bottle Jack

Hydraulic Sizing & Structural Safety Factors:

Based on Pascal's law of hydrostatic multiplication, manual lever pumping action is converted to hydraulic pressure within the reservoir base. Thick-walled cylinder hoop and longitudinal stresses were calculated via Lamé equations, paired with Euler-Johnson ram buckling verification under off-center loading.

Key Engineering Highlights:

• Structural design safety factor (SF ≥ 3.0) guaranteeing zero rupture risk under proof load.
• Integrated safety overload bypass valve preventing over-pressurization.
• Precision GD&T machining tolerances on piston ground surfaces and polyurethane U-cup seal grooves.
