Water purifier water efficiency whole machine function test bench is designed according to the relevant test requirements proposed by the customer the relevant standards of GB34914-2021. The test system is mainly suitable for the evaluation of the comprehensive use of the performance test and water efficiency of the water purifier as a whole. It is suitable for production line and laboratory test use, and the equipment is simple to operate without special operation.

1.2 self-developed test system is adopted, and the main body is composed of 3-12 workstation whole machine test platform, constant temperature and constant pressure water supply system, control cabinet and other main components.

1.3 The test platform is electrically insulated, and the 17-inch touch screen computer is used to control and by PLC control, so as to detect and control the test parameters such as water supply pressure, water pressure, water supply temperature, water outlet flow, and stall pressure in real. And it can record relevant test parameters, automatic collection and processing function of test data, automatic establishment of test database, which can be inquired at any time, and data is saved. It can display test parameters in real time, and store and record test results at the same time, such as the number of tests, test pressure, etc.; users export through USB.

The water supply test bench is assembled by aluminum profile, and the structural design adopts integrated structure. The equipment cover plate is made of 304 stainless steel. The overall appearance of the equipment is coordinated and beautiful. The internal pipeline is assembled by welding 304# and PPR pipeline. The output joint adopts the plug joint of the water purifier, which is composed of 3-way and 2-way. All main components are subject to anti-rust treatment. The working medium be recycled, and the water during the test can be automatically recycled to the water tank/drained directly.

1. The test platform is used with constant pressure water supply and the constant test water pressure is output to the pipeline through external frequency conversion constant pressure water supply, and the pressure is released and returned through the manual pressure regulating valve, and eachstation is equipped with independent pressure gauge display, electric parameter display, frequency conversion electric, and municipal electricity supply.

2. The test platform has three main outputs, and different test waters can be switched through the switch. Constant temperature water/mixed water/pure water and other single pipeline output, users can switch and use according to the actual test.

The water inlet solenoid valve life test bench is mainly used to test the durability life test equipment for water valves of household appliances such as water purifiers, dishwashers and washing machines. The machine frame structure is assembled by industrial aluminum profiles, and a multi-workstation design is adopted. The control system uses 7-inch touch screen  LC control, and users can freely define and select all test data and test modes. Frequency conversion water pump constant pressure water supply, water supply test at RT10-8 degrees water temperature. Through the running current, the water level switch senses real-time monitoring of the test product. It replaces manual operation test, effectively improves work efficiency, reduces test safety hazards, and improves detection speed and data accuracy.
