The fully automatic constant pressure testing machine (hereinafter referred to as the testing machine) is an advanced equipment for testing the mechanical properties of materials.
Through a microcomputer and hydraulic servo system, it can accurately and constantly control the stress rate during the loading process and automatically complete the entire testing cycle.
Mainly used for compression testing of metal and non-metal specimens such as concrete, cement, bricks, etc. Suitable for construction, building materials, highways, bridges, mines and
other engineering construction units.
1、 Equipment technical specifications and testing method standards followed
1. GB/T 2611 "General Technical Requirements for Testing Machines"

2、 Working conditions:
1. Range of room temperature 10-30 ℃
2. Horizontal installation on a stable base surface
3. No vibration, no corrosive medium, no dust environment
4. Power supply voltage 380V
3、 Maintenance and upkeep
1. The maintenance of the level of the testing machine may be disrupted by certain reasons, so the level should be checked regularly. If the level exceeds the specified range, it should be
readjusted.
2. The testing machine should be wiped clean regularly, and surfaces that have not been painted should be wiped clean before applying a small amount of rust proof oil.
3. The piston of the testing machine shall not rise beyond the specified position.
