DC 12V Motor Mini Vacuum Pump 370 Micro Air Pump Booster Pump Medical Pump Negative Pressure Suction Pumping Booster With Inlet And Vent,2 PCS

Test condition:
The standard of environment test is the ambient temperature of 20 ? and relativehumidity of 65?RH?If no disputes occur?the test can be conducted under the blow circumstance:the ambient temperature of 5-45 ?and relative humidity of 30?80? RH?
Rated voltage:12.0V
Operating voltage:11.5-13.0V
Curren:?650mA(During pressurization from 0 to -55KPa at DC 12.0V voltage)
Gasp time:?10s(less than 10 seconds to pressurize from 0 to -55Kpa with 12.0V in a 100CC tank)
Noise?Less than 55dB(Put a sponge of 5cm under the pump and distance to noise meter from 30cm.and while pressurizing from 0 to -50Kpa to test noise value at 12.0V voltage?FIG1?)
Max.Vacuum pressure:?-55Kpa(Rated voltage)
Flow LPM:?4.5 LPM(Rated voltage)
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 two hours.Under this circumstance ?running through test 3.3 3.4 3.5 3.6 3.7 3.8 3.9 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 two hours?Under this circumstance?running through test 3.3 3.4 3.5 3.6 3.7 3.8 3.9 and finding out that the pump still performs well.
Life test:
In a 100CC tank?pressurizing for 10seconds?stopping for 2 seconds?and deflating for 5 seconds is as one cycle?Doing it for 50?000 times?then examine the pump by test 3.3 3.4 3.5 3.6 3.7 3.8 3.9 and figure out that the pump is still in a good function.
Unusual test:
There is no burning and smoking occurrence while the power is on with DC 12.0V for 8 hours continuously
