Judging the working condition of exhaust end of 3v dc mini air pump

The above problem is to discuss the suction end resistance of the pump. According to these conditions, the range of selection has been reduced, but the problem of exhaust end resistance must be considered. In this way, the optional range can be determined.

In practical application, the exhaust condition of the micro vacuum pump is different: one is that the exhaust is very smooth and goes straight to the atmosphere; the other is the high exhaust resistance, such as valves, small bends, and large damping sensors on the exhaust pipe road, Non-specific silencers, exhaust below liquid level, gas to airtight or semi-closed containers, etc. In modern design and manufacture, the micro vacuum pump with different exhaust conditions is treated differently. " The parameter of the maximum resistance Por value "is to calibrate the exhaust capacity of the pump, so we can use strict technical means to determine whether the type selection is appropriate or not."

According to the above steps, we have been able to determine the selection range of the micro pump. The allowance should be left for the selection of the attention parameters, especially the flow parameters. After the pump is connected to the gas path system, the pressure loss will be caused by the pipeline, valve and other gas elements, so the flow rate is smaller than the nominal flow rate of the pump, and some problems related to the selection of the pump are listed below, which are considered according to the application situation.

 
Remark: Usually our pump has 4 kinds of voltage:6V, 9V,12V and 3V.
When you choose pump, you can tell me the pump's voltage you need.
We can do it for you.

3v dc mini air pump's picture

 

Working principle: the rotary motion of the motor turn into the swing of connecting rod which makes the diaphragm up and down motion. In the process of the downward movement of the diaphragm, pump cavity will suck medium through the inlet valve; Upward movement of the diaphragm, pump cavity press out media through the outlet valve. Mechanical transmission parts and pump cavity is isolated by diaphragm. Diaphragm pump does not need oil for auxiliary lubricating, in the process of transmission, extraction and compression of medium.
