Special sealing tester for electric acoustic toothbrush

The big problem of electric toothbrush is poor sealing, water inflow, maintenance The main cause of water inflow is sealing ring At present, the mainstream sonic toothbrush in the market is waterproof through sealing ring There are about four kinds of sealing rings, which are made of rubber materials Because of the characteristics of rubber, it is easy to mould and age, and then it will be lost The original elasticity makes it hard and brittle, resulting in cracks, water inflow, main board corrosion and electrical failure Therefore, the sealing test of electric acoustic toothbrush has become an important process for Zui of every common product before leaving the factory How to operate it is a small part to analyze the parameters and use methods of negative pressure sealing tester of electric acoustic toothbrush for you Product Name: special sealing tester for electric acoustic toothbrush experiment principle: the negative pressure sealing tester for electric acoustic toothbrush is to detect the sealing of electric toothbrush by using compressed air to generate negative pressure through the vacuum element group By vacuuming the vacuum chamber, the pressure difference between the inside and outside of the electric acoustic toothbrush immersed in water is produced, and the gas escaping or water penetrating into the electric acoustic toothbrush in the vacuum chamber is observed to determine the sealing performance of the test sample Technical index of special sealing tester for electric acoustic toothbrush: 1 Measurement range: - 90 ┄ 0kpa (Note: display pressure, display positive value) 2 Measurement accuracy: Level 1 3 Inner volume of test cylinder: φ 270mm × 200mm 4 Average air consumption: 70L / min 5 Net weight of equipment: 10kg 6 Self provided stable compressed air source 7 Compressed air pressure range: 0.7-1.0 MPa structure feature: mainly composed of special transparent vacuum chamber (plexiglass barrel), vacuum generation system, compressed air source (the outlet pressure of the customer's own gas source is 0.7-1.0 MPa), pressure gauge, etc The main engine is mainly composed of solenoid valve, vacuum conversion device and pressure sensor Through PLC controlling the opening and closing of the solenoid valve to control the input and output of the pressure, different test processes are realized At the same time, the pressure and holding time of the vessel are displayed Executive standard: gb15171 key words: electric acoustic toothbrush sealer, electric acoustic toothbrush negative pressure sealer, electric acoustic toothbrush sealer, waterproof electric toothbrush sealer, electric toothbrush sealer, electric toothbrush sealer, children waterproof electric toothbrush sealer
