Micro Air Pump ZR370-02PM Specification 1. Scope of application This specification is suitable for miniature air pump ZR370-2PM DC:4.5V DC:6V DC:12V DC:24V 2. Test conditions: ambient temperature 20, relative humidity 65%RH is the standard Test in the following environment: ambient temperature 5-45 , relative humidity 30-80% RH 2-2 Test orientation: 2-3 load: air air 3. Performance: 3-1 Rated voltage DC:4.5V DC:6.0V DC:12V DC:24V 3-2 Use voltage DC4.0V~5.0V DC5.2V~6.5V DC10.8V~13.2V DC21.6V~26.4V 3-3 Load current 500mA 420mA 280mA 120mA Note: The above load current refers to the current value when the rated voltage supply air pump is used to inflate to the highest pressure in a 100ml container. 3-4 Noise: Put a 5cm thick sponge under the pump body and place it 30cm away from noise meter The suction pressure is measured from 0 to -40kpa under rated voltage. Less than 65dB 3-5 Flow: 2.5 LPM 3-6 Maximum pressure: The maximum pressure value when the suction pressure is increased from 0 to stop when the rated voltage is used -55kpa 3-7 Operating temperature range: The air pump works well between temperature 5 to 50 and humidity 30%RH to 80%RH. 3-8 Storage temperature range: Keep the air pump in good condition between temperature -20 to 60 and humidity 30%RH to 85%RH. 4. Reliability test: 4-1 Low temperature characteristics: After placing it at -20C for 72 hours, take it out and place it at room temperature (20C5C) for 2 hours. Re-test checks 3-3 3-4 3-5 3-6 The test results are normal. 4-2 High temperature characteristics: After being placed at 60C for 72 hours, take it out and place it at room temperature (20C5C) for 2 hours. Re-test checks 3-3 3-4 3-5 3-6 The test results are normal. 4-3 High temperature and high humidity: Leave out for 72 hours in an environment with a temperature of 60C and a humidity of 80-85% and place it at room temperature (20C5C) for 2 hours. Re-test checks 3-3 3-4 3-5 3-6 The test results are normal. 4-4 Low-temperature environment test: After 5 hours at 5, there is no abnormality in the test at this temperature.4-5 High temperature environment test: There is no abnormality in the test at this temperature after 5 hours at 50. 4-6 Life test: In a 500ml container, open for 10 seconds and stop for 5 seconds as a cycle test. After 30,000, follow the test requirements of 3-3 3-4 3-5 3-6 Pressure within the attenuation range of 15%. 5. Other 5-1 Drop test: Use standard packaging methods and place them on the concrete floor from the front, side, and corners from a height of 50cm. Its performance and structure are not abnormal in free fall. 5-2 Abnormal test: There is no burning or smoke after continuous power-on for 8 hours at the maximum voltage. 5-3 Motor terminal: There is no abnormality with 0.3 kg weight and terminal load. The terminal must be soldered at a soldering iron temperature of 380, and the operation must be completed within 2S 5-4 Appearance: The product must not be damaged or dirty.
