Wholesale Low Temperature Impact Tester - JBW-150/300/500/750H Microcomputer Controlled Metal Pendulum Impact Testing Machine – Chengyu Detail:

Application

The machine can be used for the determination of anti-impact performance of metal materials when it is under dynamic loading, thus judged the quality of materials under dynamic loading. It is applicable for the laboratory, which does continuous compact tests, metallurgy, machinery manufacturing, and other industries.

Key Features

(1) Main frame and foundation is integration, good stiffness and high stability.

(2) Axle of rotation adopts simple strut-beam, good stiffness, simple and reliable structure and high precision.

(3) Round pendulum makes wind resistance to mini.Impact knife adopts wedge block to compress and install.It is easy to exchange.

(4) Suspension pendulum device adopts hydraulic buffer to avoid damage and low noise when hang pendulum.It extends service life and improves safety.

(5) This machine adopts reducer to transport. Its structure is simple, easy to install and maintain, long service life and low breakdown rate.

(6) Three kinds of display modes, they display at the same time.Their results can compare with each other to remove possible problems.
