DC Vacuum Pump Small DC Pump For Suction Machine 3.7VDC 2.0L/M
| Test Environment | Ambient temperature of 20℃ and relative humidity of 65%RH. |
| Position | Horizontal |
| Load | Air pressure 300mmHg |
| Operating condition | 5℃~45℃, RH 30%~85% |
| Storage condition | -20℃~60℃, RH 30%~85% |
| Rated voltage | 3.70VDC |
| Operating voltage | 3.0 - 4.5 VDC |
| Rated current |
＜650 mA；The highest current is less than 650mA while pressurizing with DC3.7V from 0 to 300mmHg |
| Inflation time | At DC3.7V to pressurize in a 100cc tank from 0 to 200 mmHg, Inflation time 6 seconds. |
| Air flow | At DC3.7V ,the air flow is more than 2.0L/min with no load.. |
| Max pressure | The maximum pressure value shall be more than 400mmHg while pressurizing with DC 3.7 V tank from 0 till dead-head pressure value |
| Max vacuum | The maximum vacuum value shall be Less than-450mmHg while pressurizing with DC 3.7V tank from 0 till dead-head vocuum value. |
| Noise | Putting a 5 cm sponge under the pump,and placing it about 30 cm away from the noise meter,The evaluated noise level shall be less then 60dB while pressurizing with DC 3.7V from 0 to 200mmHg. |
| Low-temperature characteristic | Putting the pump in the temperature at negative 20℃ for 72 hours;then taking it out and putting it in a room temperature at 20± 5℃ for 2 hours,Under this circumstance,running through performance test and finding out that the pump still performs well. |
| High-temperature characteristic | Putting the pump in the temperature at 60℃ for 72 hours; then taking it out and putting it in a room temperature at 20 ± 5 ℃ for 2 hours,Under this circumstance,running through perforamance and finding out that the pump still performs well. |
| High-temperature & High humidity | Putting the pump in the temperature at 60℃ and the humidity at 95% for 72 hours;then taking it out and putting it in a room temperature at 20 ± 5 ℃ for 2 hours.Under this circumstance,running through performance test and finding out that the pump still performs well. |
| Temperature & humidity cycle test | After doing the temperature and humidity cycle test,-20℃* 2Hr → +25℃* 1Hr→ +60℃ 85%RH* 2Hr →+25℃*1Hr,for twelve times,the pump shall still perform the same functions proved by running through performance test. |
| Life test |
In a 500CC tank,pressurizing for 10 seconds , stopping for 2 seconds,exhaust for 5 seconds is as one cycle,Doing it for 30,000 times, then examine the pump by testing performance and figure out than the pump is still in a good function. |
