Washing Machine Mechanical Life and Reliability Test Equipment, this type of equipment simulates long- use to inspect the durability of washing machines. The washing machine test equipment long-run life test bench allows the washing machine to operate continuously for standard or accelerated wash cycles in an unatt state, simulating years or even decades of use, and inspecting the durability of core components such as the motor, bearings, door lock, and shock absorption system. Door Cover/or Seal Life Door cover opening and closing life test machine, washing machine energy efficiency test equipment, through the mechanical arm to simulate the user's opening and closing the door cover action for tens of thousands to hundreds of thousands of times of repeated testing, inspecting the durability of door hinges, door locks and door seals. Controller/Button Life Button switch life machine, using a pneumatic or servo motor driven plunger, to press and rotate the buttons and knobs on the control panel repeatedly, testing their operation feel and reliability. 3. Safety and Safety Standard Test Equipment This type of equipment ensures that the washing machine complies with mandatory safety standards, preventing risks such as electric shock, fire, leakage. Pressure Test Instrument, a high voltage (such as 1500V) is applied between live parts and the case to test whether the insulation strength sufficient to prevent leakage. Grounding Resistance Tester, measures the resistance of the grounding line to ensure that current can be safely introduced into the ground in the event of a leakage Leakage Current Tester, measures the weak current flowing to the ground line when the washing machine is working normally, to ensure that it is within the safe range. Washing Energy Efficiency Test Equipment, stability, tilt test bench to place the washing machine on a certain angle of the inclined plane, to test whether it is stable, will it tip over Stall Test System simulates the extreme situation of the motor being jammed, monitors the motor temperature rise and current, and inspects whether the overheat protection device can operate in time burning out. 4. Environmental Simulation and Component Test Equipment This type of equipment is used to test the adaptability of washing machines in extreme environments and the performance of key. High and Low Temperature Cyclic Humidity and Heat Test Chamber, washing machine test equipment places the washing machine in high temperature (such as 40°C), temperature (such as -15°C) or high humidity environment, to test its start-up, operation performance and whether the components (such as plastic parts) are aging brittle. Waterway System Test, Water Hammer Pulse/Pressure Burst Test Machine Simulate the sharp fluctuation of water pressure in the pipeline (water hammer effect) and carry out pulse pressure test on the washing machine's inlet pipe, valve and inner tub to inspect their pressure resistance and sealing. Noise and Vibration, Sound Level M, Vibration Analyzer in the sound insulation room or semi-sound insulation room, measure the noise decibel value and the vibration amplitude of the whole machine in different conditions such as spin drying, washing, etc. Washing Machine Energy Efficiency Test Equipment, 5. Intelligent and Function Verification Equipment Washing Machine Test Equipment the improvement of the degree of intelligence of washing machines, the corresponding test equipment has also developed accordingly. Communication Function Tester: Used to test the connection stability and data transmission accuracy of-Fi, Bluetooth and other modules. Sensor Calibration Equipment: Used to calibrate sensors such as weighing (load sensing), water temperature, turbidity, etc. to ensure that their readings are accurate. The design and use of the above equipment are all around the domestic and foreign standards, mainly including: China National Standards (GBT): GB/T 4288 (Performance), GB 4706.1 and GB 4706.24 (Safety)International Standards (IEC): IEC 60456 (Performance), IEC 60335-2-7 (Safety
