Electric DC12V mini air pump for smart toilet

Is the micro diaphragm air pump pushed or pulled?

During this process, the Small DC Air Pump has both a push and pull action. Specifically, when the diaphragm moves to one side, it compresses the air inside the pump chamber, creating positive pressure that pushes the gas out of the exhaust port. When the diaphragm moves to the other side, the air inside the pump chamber is stretched, forming negative pressure, which will "pull" external gas into the pump chamber through the suction port.

Therefore, during the operation of the micro diaphragm air pump, there are both actions of pushing and pulling the gas, and these two actions are carried out alternately.

What are the suction and exhaust ports of a micro diaphragm air pump?

Micro diaphragm air pump, also known as micro vacuum pump, has an inlet and outlet suction nozzle and exhaust nozzle. The suction port, commonly referred to as the intake or suction port, is mainly used to suck in external gas. When the diaphragm moves towards the side that generates negative pressure, the negative pressure at the suction port will attract external gas into the pump chamber. The exhaust port, also known as the air outlet or discharge port, is mainly used to discharge gas that has already been compressed through the pump chamber. When the diaphragm moves towards the side that forms positive pressure, the positive pressure in the pump chamber will push the gas out of the exhaust port.

These two ports play a crucial role in the operation of the pump, working together to enable the micro diaphragm air pump to complete the suction and discharge of gas, thereby achieving its pumping function.

How do the suction and exhaust ports of a micro diaphragm air pump work?

The working principle of the suction and exhaust ports of a Small DC Electric Pump is closely related to its internal structure and the movement of the diaphragm. Here is a brief description of how they work:

The working principle of the exhaust port:

When the diaphragm moves to one side (such as to the left), the space inside the pump chamber will increase, forming negative pressure.

This negative pressure will attract external gas into the pump chamber through the suction port, filling the space generated by the movement of the diaphragm.

The design of the suction port usually has a certain suction area and an appropriate inlet channel to ensure that gas can smoothly enter the pump chamber.

The working principle of the exhaust port:

When the diaphragm moves to the other side (such as to the right), the space inside the pump chamber will decrease, forming positive pressure.

This positive pressure will push the gas inside the pump chamber out through the exhaust port.

The design of the exhaust port will ensure that gas can flow out of the pump chamber smoothly under positive pressure without blockage or backflow.

Throughout the entire working process, the mini electric air pump continuously alternates between compressing and stretching the gas inside the pump chamber, resulting in continuous gas flow. This working method enables the suction and exhaust ports to periodically complete the tasks of suction and discharge of gas, thereby achieving the overall function of the micro diaphragm air pump.

It is worth noting that the design and size of the suction and exhaust ports have a significant impact on the performance of the pump, including flow rate, pressure, and efficiency. Therefore, when selecting and using micro diaphragm air pumps, it is necessary to choose appropriate suction and exhaust port configurations based on specific application scenarios and needs.

What units are used to represent the pressure of a micro diaphragm air pump? What is the pressure PSI of a micro diaphragm air pump?

The pressure of a portable electric air pump is usually expressed in pressure units, commonly used units include pascals (Pa), kilopascals (kPa), bars (bar), atmospheric pressure (atm), and pounds per square inch (psi). Among them, psi (Pound force per square inch) is a commonly used unit in the United States, especially in the automotive industry and some industrial applications.

The specific pressure value of a Dc Air Pump depends on the pump's design and manufacturing specifications, as well as the pump's application scenario. Different micro diaphragm air pumps may have different maximum and minimum working pressure ranges. Therefore, to answer the question of "What is the pressure PSI of a micro diaphragm air pump", it is necessary to know which specific pump it is and its design parameters.

Usually, the working pressure range of the pump, including maximum working pressure and recommended working pressure, is clearly indicated in the pump specifications or product manual. If there is no specific product manual, you can contact the manufacturer or supplier for accurate information.

Additionally, it is worth noting that psi is an imperial unit, and in some countries that use metric units, such as China, pressure and pressure are more commonly expressed in pascals (Pa) or kilopascals (kPa). In practical applications, it is necessary to select appropriate units based on specific needs.
