I. main uses:

According to GB177-85 and GB17671-1999 "Test Method for Compressive Strength of Cement Rubber Sand", YAW-300D microcomputer-controlled full-automatic compressive and flexural testing machine is used for compressive and flexural strength test of cement Rubber Sand conforming to GB/T17671-1999 standard. It adopts double-station test space, has dual-purpose, saves space and anti-compressive and flexural strength. Data automatic integration, simple operation and other advantages. The product has the characteristics of high accuracy, superior performance, high reliability and easy operation. This machine is fully in line with GB/T3722-92 and GB/T2611-92 standards. Can provide you with accurate experimental results. It is mainly used for compressive and flexural strength test of cement mortar and cement clay, rubber pad, tile, metal products, components and other materials. It is an ideal test equipment for scientific research institutes, cement quality inspection, industrial and mining enterprises, cement, mortar and other departments.

Two, functions and characteristics:

1. no pressure oil leakage and proportional valve blockage and other bad phenomena, low noise and high reliability.

2. Chinese windows control and processing software, user-friendly design, beautiful interface, simple operation. It can set the holding value, keep the pressure time, and automatically calculate the test results.

3. the advanced automatic control function can carry out single or batch tests on the specimen.

4. It has the control mode of constant velocity stress and test force maintenance, realizes the setting of test parameters, data acquisition, analysis, storage and printing.

5., the corresponding control software can be configured according to national standards or user requirements.

6. after the specimen is damaged, the moving beam stops moving automatically (or automatically returns to the initial position).

7. program control and mechanical two level limit protection;

8., when the load exceeds the rated value of 3 ~ 5%, automatic shutdown.
