The vacuum cleaner hose torsion test machine is designed and manufactured according to the requirements of Article 21.104 of GB4706.7-2008 and GB4706.61-2008 standards, as well as IEC60335-2-2 and IEC60335-2-54 standards. During the test, the hose is fixed on the horizontal axis of the device, and the horizontal rotation axis is rotated forward by 5 turns and then backward by 5 turns, with a cycle test of 2500 times. After the test is completed, the sample is subjected to electrical strength test. The test bench adopts PLC program control and sets and records relevant parameters through a 7-inch touch screen
