1. Core Principle: Pascal's Law for Efficient Hydraulic Energy Conversion

Zhenghao YoubangHydraulic PressBased on Pascal's Law (the principle of equal pressure transmission in confined fluids), hydraulic oil serves as the working medium. The hydraulic pump converts mechanical energy into hydraulic energy, which is then converted back into mechanical energy via control valves and cylinders to drive the slider for linear reciprocating motion. This enables processes such as pressing, stretching, bending, and blanking. As a specialist...Hydraulic Press R&D and ManufacturingThe company optimizes core energy conversion logic with Zhenghao Youbang: Motor → Hydraulic Pump → High-Pressure Oil → Cylinder → Slider → Workpiece Forming.
