1. Meet the standard:

IEC61215-2 MQT16
IEC61215-2 MQT20
IEC61730-2 MST34
IEC TS 62782:2016

2. Product Introduction:

The cylinder type mechanical load testing machine is designed and manufactured in accordance with relevant standard clauses such as IEC61215-2 IEC62782 TS Ed.1. The mechanical load testing machine is used to verify the ability of components to withstand static and dynamic loads under wind, snow, or icing conditions. This machine is used to test the compressive strength of photovoltaic modules. It adopts dynamic holding pressure technology and simulates load tests to evaluate the product's compressive ability under load conditions.

3. Test objective: To determine the ability of the component to withstand static loads such as wind, snow, or icing.

4. Design Description:

The system simulates dynamic loads in the form of cylinders and suction cups, with pressure applied through suction cups, pressure sensors, cylinders, proportional valves, and PLC. Each cylinder drives one suction cup, and a tension pressure sensor is installed on the piston rod of each cylinder. The air pressure is calculated by the PLC based on the real-time feedback value of the pressure sensor, and the cylinder movement is controlled by adjusting the proportional valve opening to achieve force control. Each cylinder is a separate control module. Perform periodic load and pressure tests on the installation plane of the components. The main frame of the system is made of 8080 Euro standard aluminum profiles, designed to accommodate the installation of pressure blocks, screw holes, and double glass components for conventional components. The device has the function of real-time monitoring of component deformation, as well as the continuity of current and component temperature during the testing process.
