What is a hydraulic pressure testing machine?
Hydraulic pressure testing machine is a kind of equipment widely used in testing the mechanical properties of materials. It is mainly used to measure the compressive strength, compression deformation and other performance indicators of metal and non-metal materials and components. Its working principle is to apply pressure through the hydraulic system to achieve precise loading of the specimen. It is widely used in construction, metallurgy, machinery manufacturing and other fields.
1. Working principle of hydraulic pressure testing machine
The hydraulic pressure testing machine pressurizes the oil through a hydraulic pump and drives the piston to move, thereby applying pressure to the sample. Its core components include hydraulic systems, control systems and measurement systems. The following are examples of its main technical parameters:
| Parameter name | Typical value | unit |
|---|---|---|
| Maximum test force | 1000-10000 | kN |
| Pressure accuracy | ±1% | - |
| Piston stroke | 100-300 | mm |
| Test speed | 0.1-50 | mm/min |
2. Application fields of hydraulic pressure testing machine
Hydraulic pressure testing machines play an important role in multiple industries. The following are its main application scenarios:
| Industry | test subject | test items |
|---|---|---|
| building materials | concrete, steel | Compressive strength, elastic modulus |
| metal material | Steel, aluminum alloy | Yield strength, compression properties |
| plastic rubber | Plastic products, rubber parts | Compression deformation, load-bearing capacity |
| automobile manufacturing | Parts and structural parts | Durability, destructive testing |
