According to the relevant testing standards for washing machines, the equipment meets the requirements for static pressure, progressive pressure, burst and other pressure holding and ultimate pressure tests on products such as balance rings. The tested products are subjected to pressure holding/burst tests with a maximum water pressure of 0.1-5.0 Mpa. Using high-precision pressure sensors for pressure value collection and judgment. Pressure constant pressure control is carried out through a testing machine PLC, which reads and records pressure values in real-time and generates pressure curves. Perform pressure judgment, leakage judgment, pressure limit judgment, etc. by setting upper and lower limits. Complete relevant experiments through parameter setting and control

-GB/T 4706.1, GB/T 4706.24 (Safety of Household Washing Machines)

-GB/T 4288 (Household Electric Washing Machines)
