IEC 60335-2 Abrasion Test Equipment For Current-Carrying Washing Machine Hose
Product Overview For Abrasion Test Equipment:
This current-carrying hoses abrasion resistance test equipment meets the standard of IEC60335-2-2, clause 21.102 figure 101. Suitable for verifying the vacuum cleaners or water-suction cleaning appliances's current-carrying hoses shall be resistant to abrasion. The equipment is controlled by PLC and operated by touch screen. The motor drives the crank mechanism to rotate at a rate of 30r/min, and the sample of the current-carrying tube is reciprocated 100 times forward and backward by 300mm through the connecting rod. At the same time, support the hose with a rotating smooth roller, and attach a belt of abrasive cloth to the outer edge of the roller, moving at a speed of 0.1m/min. The abrasive of the emery cloth is corundum, and the particle size is Pl00 according to the provisions of ISO 6344-2. The other end of the hose hangs a weight with a mass of 1kg as a guide to prevent the hose from rotating. In the lowest position, the maximum distance of the weight from the center of the roller is 600 mm. After the test, the basic insulation shall be free from leakage and the electric strength test of 16.3 is carried out between the connected conductors and the saline solution.
Technical Parameters For Abrasion Test Equipment:
Test Procesures For Abrasion Test Equipment:
One end of the hose is attached to the connecting rod of the crank mechanism shown in Figure 101. The crank rotates at 30 revolutions per minute resulting in the end of the hose moving horizontally backwards and forwards over a distance of 300mm.
The hose is supported by a rotating smooth roller over which a belt of abrasive cloth moves at a speed of 0.1 m/min. The abrasive is corundum grit size P 100, as specified in ISO 6344-2. A mass of 1 kg is suspended from the other end of the hose, which is guided to avoid rotation.
In the lowest position, the mass has a maximum distance of 600 mm from the centre of the roller.
Test test is carried out for 100 revolutions of the crank.
After the test, basic insulation shall not be exposed and the electric strength test of clause 16.3 is carried out between the conductors connected together and the saline solution.
