How many volts is the voltage of the micro electric vacuum pump used for the blackhead remover? Why?
The choice of voltage for the mini vacuum pump used for the blackhead remover mainly depends on the product design, safety requirements and power source. Generally speaking, considering the convenience and safety of users, most blackhead removers use low voltage, usually converted to a lower working voltage through an adapter. Specifically, a DC voltage of several volts to more than ten volts may be used.
There are several reasons for such voltage selection:
1. Safety: Low voltage can effectively reduce safety risks during use, especially in a home environment, avoiding possible electric shock injuries.
2. Applicability: Powered by a power adapter or USB interface, the low-voltage dc vacuum pump can directly obtain energy from a common power source, which is convenient for users to use.
3. Efficiency and performance: For small devices such as blackhead removers, low-voltage micro vacuum pumps are usually sufficient to provide the required suction and realize the main functions of the product.
4. Cost: Low-voltage micro vacuum pumps are usually cheaper, which helps to reduce the overall cost of the product.
Can the medium of a micro membrane vacuum pump be water? Why?
The medium of a small diaphragm vacuum pump can be water. The working principle of a diaphragm vacuum pump is mainly to compress and stretch the air in the pump chamber to form a vacuum through the circular motion of the motor and the mechanical device to make the diaphragm inside the pump do reciprocating motion, thereby generating a pressure difference with the external atmospheric pressure at the suction port, sucking the gas into the pump chamber, and then discharging it from the exhaust port. Due to this working principle, the diaphragm vacuum pump can handle a variety of media including water.
However, it should be noted that although the micro diaphragm vacuum pump can handle water, it is not suitable for all types of water. For example, it cannot handle gas phase water or high temperature water vapor, which may affect the performance and service life of the pump. At the same time, when the amount of water in the container is too large or contains other liquids or solids, it may be necessary to increase the pumping time of the pump and the role of the filter to protect the diaphragm and ensure the normal operation of the pump.

Do miniature diaphragm vacuum pumps have PSI? Why?
Micro diaphragm vacuum pumps usually do not use PSI (pounds per square inch) to describe their performance, because the performance parameters of micro diaphragm vacuum pumps are usually described using vacuum (such as mmHg, Torr, mbar, etc.), because vacuum is a unit that more directly and accurately reflects the performance of vacuum pumps.

How do I choose a electric vacuum pump capacity?
The capacity of a dc motor diaphragm vacuum pump is one of its performance parameters and has the following main functions:
1. Determine the exhaust capacity of the pump:
The capacity is usually expressed in liters per second, liters per minute or liters per hour. The larger the capacity, the more gas the vacuum pump can exhaust per second.
For example, when a large amount of gas needs to be processed or a vacuum environment needs to be formed quickly, a high-capacity vacuum pump will be more effective.
2. Affect the stability and efficiency of the system:
The appropriate capacity helps to maintain the stable operation of the system. If the capacity is too small, the pump may not be able to exhaust the gas in the system in time, thus affecting the formation and maintenance of the vacuum environment.
On the other hand, if the capacity is too large, it may increase energy consumption and costs, and may also cause unnecessary waste.
3. Determine the selection of the pump:
When choosing a micro diaphragm vacuum pump, capacity is an important consideration. Depending on the specific application requirements, a pump with the appropriate capacity can be selected.
For example, if a large amount of gas needs to be processed, a pump with a larger capacity may need to be selected; while if only a small, low-power vacuum requirement is required, a pump with a smaller capacity may be selected.
4. Relationship with parameters such as flow rate and pressure:
Capacity is closely related to parameters such as flow rate and pressure. Generally speaking, the larger the capacity, the greater the flow rate, but the pressure may be relatively low. Therefore, when choosing a vacuum pump, these parameters need to be considered comprehensively to ensure that the performance of the pump meets the needs of the system.

How to choose the capacity of a micro electric vacuum pump?
The following factors need to be considered when selecting the capacity of a small electric vacuum pump:
1. Required vacuum degree: Different applications require different vacuum degrees. Generally speaking, applications that require higher vacuum degrees require vacuum pumps with larger capacities.
2. Gas type: Different types of gases have different effects on vacuum pumps, so you need to select a vacuum pump that is suitable for the required gas.
3. Pump speed: Pump speed refers to the volume of gas pumped out per unit time. You need to select a suitable pump speed based on application needs.
4. Working time: You need to consider the comprehensive factors of the required vacuum degree, pump speed, and working time, and select the appropriate capacity to meet work needs.
