COMPRESSION TESTING MACHINE
Make Dinesh Scientific
DESCRIPTION
A laboratory device called a compression testing machine, sometimes referred to as a concrete compression machine or a cube testing machine, is used to determine the compressive strength of materials, especially concrete. One important factor in determining the endurance and quality of concrete structures is their compressive strength.
An overview of a compression testing apparatus is provided below:
THE LOADING UNIT AND FRAME:
- Usually, the machine is made composed of a strong frame that supports the entire device structurally.
- Applying the compressive force to the test specimen is the responsibility of the loading unit.
THE HYDRAULIC SYSTEM
- Hydraulic systems are used by the majority of contemporary compression testing equipment to apply and regulate load. The hydraulic system makes sure that force is applied steadily and smoothly.
LOADING CELL
- A transducer that transforms an applied force into an electrical signal is called a load cell. It is a necessary part for precisely calculating and documenting the compressive force.
PLATEN OR PISTON:
- A piston or platen is used to transfer the compressive force to the test specimen. The size and kind of the specimens being evaluated determine the form and dimensions of the piston or platen.
PANEL OF CONTROL:
- The testing machine’s controls and settings are located on the control panel. It has functions like emergency stop, load retention, and load rate modification.
DIGITAL INDICATOR OR INFORMATION GATHERING SYSTEM:
- These days, a lot of compression testing apparatuses have data collecting systems or digital displays. These systems provide precise measurements and data processing by providing real-time monitoring of the applied load and displacement.
MACHINE SAFETY FEATURES
- Pressure Valves to Avoid Overloading
- Limit Switch for Piston Stroke
- Emergency Stop Button
- Removable Transparent Front and Rear Safety Doors
- Software Controlled Load Value.
