ISO23953-2 Vertical Refrigerator Door Opening And Closing Testing Machine Durability Test

System overview:

The vertical refrigerator door opening and closing test machine is designed and manufactured according to Chapter 5.3.3.2 of ISO 23953-2:2015(E) and customer-specific requirements. It is used for the vertical door opening and closing durability test of vertical refrigerators, also used to match the door opening and closing actions during energy efficiency performance of refrigerators. It is a dedicated fully automated testing equipment for testing the opening and closing of refrigerator doors, which is suitable for testing departments such as testing and certification agencies, factory laboratories, etc.

This equipment adopts PLC intelligent control with mature technology, equipped with position-adjustable action actuator, and vacuum suction cup structure to absorb the surface of the refrigerator. At the same time, it is equipped with a color LCD touch screen as standard, which can preset the door opening angle, door opening and closing speed, door opening pause time, and interval time. In this way, it can truly simulate the opening and closing of the refrigerator door by hand, and achieve an intelligent control method, one machine with multiple functions.

Equipment principle:

Equipment principle: PLC control, intelligent touch screen operation, servo motor drives the manipulator, drives the door which is sucked by the vacuum suction cup to be opened and closed reciprocatingly.

Process flow:

The structure of the testing machine as shown in the figure below, the overall frame structure is adopted, and the sample is placed on the bottom plate of the equipment, so that the relative movement is the internal stress, and the shaking of the equipment is reduced. A column structure is installed on the bottom plate, and the column contains a set of doors opening and closing mechanism as shown in Figure 1. At the same time, the refrigerator positioning fixture is installed on the bottom plate, which can clamp and fix the left, right and rear sides of the refrigerator. Applicable samples are as shown in Figure.
