The working progress of water ring vacuum pump has a certain relationship with its power supply mode, so we need to know its power supply mode. It doesn't matter how much you know about its power supply mode. But the following describes its power supply mode.
1. Water ring vacuum pump because the medium extracted is "water or liquid", the specific gravity is large; while the working medium of micro vacuum pump and micro air pump is "gas", the specific gravity is relatively light; therefore, the working current of vacuum pump is generally larger than the latter, about 1 ~ 10 amperes, while the working current of the latter is generally small, ranging from hundreds of Ma to several amperes.
2, battery is the general term of battery, because principle and dry battery, can provide larger current and power, widely used in electric vehicles, cars and other mobile vehicles, agricultural spraying spray, field sampling and other occasions where there is no power supply.
3. The commonly used dry batteries (such as 1, 5V batteries) have large internal resistance, and the current provided by them is small, and a large part of the voltage is consumed on the internal resistance. Therefore, the voltage drops rapidly. Considering the power and service time, it is suitable for the water supply ring vacuum pump.
