Introduction to YAW-300D microcomputer-controlled constant stress testing machine

1. Main functions

The testing machine consists of a mainframe, servo oil source, control cabinet, and a PC system for control. The mainframe adopts a mobile crossbeam with an oil cylinder placed underneath, allowing the mobile crossbeam to adjust the testing space within the range of 0-1200mm. The machine is microcomputer-controlled, with automatic constant-speed loading to complete the testing process. It can be used immediately after being placed on a level, horizontal surface. It is suitable for compressive strength testing of building materials such as rocks, concrete, cement products, hollow bricks, fly ash bricks, and refractory materials. It meets national standards and can automatically calculate the result parameters specified in various relevant standards. It is mainly used by product quality supervision departments, engineering quality inspection, universities and colleges, and large industrial and mining enterprises.

II. Main Features:

1. This machine utilizes high-precision sensors and computer control, enabling automatic storage, retrieval, and printing of test reports.

2. This machine utilizes a rotary screw to adjust the compression space, significantly speeding up the testing process.

3. The machine can design reports independently according to the requirements of the unit.
