YAW-300B microcomputer controlled fully automatic pressure testing machine

1. Product use

This machine is mainly used for compressive strength testing of cement mortar, carbon materials, petroleum proppant and other materials. It can also be used for mechanical property testing of other materials. It meets the requirements of GB/T2611, GB/T17671, GB/T16826, and GB/T50081 standards.

2. Product description

The testing machine uses a high-performance AC servo motor to drive the precision screw operation. The high-performance control system can realize automatic control and arbitrary programming control of multiple modes such as constant-rate stress, constant-rate displacement, constant-speed deformation, etc.;

The main unit of the testing machine adopts a bottom-mounted main unit, which can quickly clamp the specimen.The whole machine is made of steel with high strength and good fatigue resistance;

Since the AC servo motor is loaded without overheating, it can meet the working requirements of 7×24 hours. Safety protection device:
