What is a hydraulic pressure testing machine?
Hydraulic pressure testing machine is a professional equipment used to test the compression performance of materials, components or products in high-pressure environments. It is widely used in construction, metallurgy, machinery manufacturing, aerospace and other fields to evaluate the strength, stiffness and durability of materials by simulating pressure conditions in actual working conditions. This article will introduce in detail the principle, classification, application and recent industry hot spots of hydraulic pressure testing machines.
1. Working principle of hydraulic pressure testing machine
Hydraulic pressure testing machines generate high-pressure liquid (usually oil) through a hydraulic system, driving a piston or pressure head to apply pressure to the specimen. Its core components include hydraulic pumps, control valves, pressure sensors and data display systems. Users can achieve precise control by setting parameters (such as pressure value, loading speed), and monitor data in real time through sensors.
