Miniature vacuum pump vacuum adjustment

Many miniature vacuum pumps do not have the ability to adjust the degree of vacuum. Only by adjusting the valve. For example, a precise pressure relief valve is connected to the pumping end of the pump. When the vacuum is high, the valve is opened and the vacuum is lowered. This fine pressure relief valve also has the directional discharge of toxic gases, etc., to the designated container's channel, which is a lot of valves have no function.

If you want to make it simpler, you can use an intelligent vacuum pump. There are buttons on the pump, you can set the negative pressure, and the LCD panel shows negative pressure. There is also a knob that can adjust the flow of large and small. This intelligent vacuum pump, also known as AC vacuum pump, digital vacuum pump.
