WH-8813I Scratch Hardness Tester Adjustable Eccentric Wheel Mechanism 50-250mm

WH-8813I Scratch Hardness Tester Adjustable Eccentric Wheel Mechanism 50-250mm ​

The machine uses a special tool to imitate the pipeline in the course of some sharp objects on

the pipeline damage.

The machine principle:

A). Using the eccentric wheel mechanism to make reciprocating motion of the knife rest, the

stroke is 50-250mm adjustable.

B).The blade holder and the linear bearing are combined with the mobile station, and can be

freely moved up and down. The resistance is almost zero. In the case of a knife, the knife holder

is easy to change. The knife and the tool holder are composed of a blade, a knife holder and a

mobile station. Put the right amount of weight on the shelf to achieve the pressure of the blade on

the sample.

C). Specimen is fixed with a special fixed sleeve and fastening ring, the fixed sleeve can be

connected with the water pump joints and valves, can control the sample pressure and drainage.

The retaining sleeve can be easily removed for easy clamping of the specimen.

D). The machine uses pressure sensors and monitoring instruments to monitor the pressure

inside the sample, so that the sample wear, the pressure dropped to the set value, the instrument

automatically shut down.

E). The pressurized system uses high-pressure water pump, can provide 0-6Mpa, and 0-10L / m

high-pressure water.
