The operation mechanism of the Jinan Dongte screen display universal material testing machine is manually controlled, allowing users to adjust the force application speed and set the calibration force value. The system also controls the fast lifting cylinder, which plays a key role in positioning and securing the test specimen. The power switch and oil pump control are located on the control panel, providing an intuitive interface for the operator.
When the oil supply valve is opened, high-pressure oil from the pump is transferred to the testing machine's cylinder via high-pressure hoses. This pressurized oil enables the movement of the crosshead, applying the necessary force during the test. On the other hand, the oil return valve allows the system to release pressure and quickly return the hydraulic fluid back to the reservoir, ensuring smooth operation and reducing wear on the components.
The solenoid valve on the control panel is responsible for tightening or loosening the tensile specimen. It’s important to note that if no specimen is installed, the solenoid valve should be turned off to prevent unnecessary wear and extend its service life. This precaution helps maintain the accuracy and reliability of the testing machine over time.
Proper maintenance and correct usage of these components are essential for achieving consistent and reliable test results. Operators should always follow the manufacturer's guidelines and ensure all valves and switches are in the correct position before starting any test. Regular inspection and lubrication of the hydraulic system can further enhance the performance and longevity of the universal material testing machine.
