DC 12V Electric Micro Vacuum Pump

DC 12V Electric Micro Vacuum Pump is a small air pump, which basically consists of motor, rotor, stator and impeller. The electric motor provides the power to turn the impeller and create a negative pressure area. Two counter-rotating impellers form the main components of the pump. When the motor is turned on, the impeller starts to spin and pushes the gas outward. The expelled gas creates an area of low pressure that allows other gases to flow into the pump from the surrounding environment. This process will continue until the pressure of the mini vacuum pump reaches the minimum limit for which it was designed. When gas gets in, it can become trapped inside the pump. In this case, the impeller creates a vortex inside that breaks the viscosity of the gas and brings it to the outlet. This process is called gas evacuation.

The working principle of the vacuum pump is to convert the electrical energy into mechanical energy, and pump out the gas when the vacuum exhausts the pump. Its core components are the impeller and the gear, and the motor drives the impeller to rotate rapidly to generate high-speed airflow to discharge the extracted gas.
Therefore, its working mechanism is to convert electrical energy into mechanical energy through the motor, and use the high-speed rotating impeller to generate a negative pressure area to pump out the gas.

Production Process

Installation method and steps:
1. First, prepare the required tools and materials, including electric micro-vacuum pumps, valves, hoses, connectors, screwdrivers, wrenches, etc.
2. Place the electric micro vacuum pump where it needs to be used, and make sure it is stable and not easy to move.
3. Install the inlet and outlet interfaces. Connect the outlet and inlet to the corresponding ports of the electric micro vacuum pump. Use a wrench to hold it tight and make sure it's well connected.
4. Install the valve. Connect the valve and hose. Connect one end to the outlet of the pump and the other end into the valve.
5. Attach a piece of hose to the other end of the valve and connect it to the device that needs to draw air or liquid with a vacuum pump.
6. Connect the pump power cord to the power supply. Make sure the connection is correct and check the cable for damage.
7. Turn on the power switch to make the 370 micro vacuum pump start to work. At this point, turn the valve to connect to the device and start the pump.
8. When venting air or liquid is required, use the outlet connection to connect the hose and open the valve.
9. After use, unplug the power cord, close the valve and outlet interface.
The above are the general steps and precautions for installing the pump. In terms of connecting the inlet and outlet interfaces and wiring, it is necessary to read the instructions carefully and install according to the instructions to ensure correct, stable and safe use
