6V DC mini vacuum pump for breast pump

What are the two most common types of vacuum pumps?

The two most common types of vacuum pumps are piston pumps and Diaphragm Pumps.

1. Piston Pump:

Working principle: Vacuum is generated through the reciprocating motion of the piston. When the piston moves in one direction, it pushes out the air in the pump chamber, forming a vacuum. When the piston moves in another direction, it will suck in new air.

Application field: Widely used in various situations that require vacuum generation, such as laboratories, hospitals, industries, and other fields.

Advantages and disadvantages: The piston pump has the advantages of simple structure, stable operation, and easy maintenance. However, due to the friction and wear caused by the movement of the piston, it is necessary to regularly replace the seals and lubricating oil.

2. Diaphragm pump:

Working principle: Vacuum is generated through the reciprocating motion of the diaphragm. When the diaphragm moves in one direction, it will push out the air in the pump chamber, forming a vacuum. When the diaphragm moves in another direction, it will suck in new air.

Application field: Mainly used in situations that require lower vacuum or flow rates, such as laboratories, medical equipment, etc.

·Advantages and disadvantages: Diaphragm pumps have the advantages of compact structure, low noise, and easy maintenance. However, due to limitations in the material and manufacturing process of the diaphragm, its lifespan may be short and it needs to be replaced regularly.

Why can't micro piston vacuum pumps be used for breast pumps? 

1. Negative pressure control issue: The breast pump needs to accurately control the negative pressure to ensure that it can effectively extract milk without causing excessive pressure or damage to the breasts. Micro piston vacuum pumps may struggle to provide precise negative pressure control and may be too strong or too weak, making them unsuitable for use in breast pumps.

2. Persistent issue: Micro piston vacuum pumps may require frequent maintenance and replacement, which can be a problem in long-term use of breast pumps. Due to the frequent use of breast pumps, they require long-lasting and stable performance.

3. Noise and vibration: Micro piston vacuum pumps may produce significant noise and vibration, which may affect the effectiveness of breast milk suction and user comfort. For users who need to breastfeed in a quiet environment, this may be a problem.

4. Cleaning and maintenance issues: Micro piston vacuum pumps may be difficult to thoroughly clean, which can lead to bacterial growth and increase the risk of infection. In addition, its complex structure may also make maintenance difficult. 

Technical Specification 

What is the difference between a Suction Pump and a vacuum pump?

The suction pump and vacuum pump are two different types of pumps, and they have some differences in the following aspects:

1. Working principle: A suction pump usually sucks in liquid through its own negative pressure, while a vacuum pump generates a vacuum through mechanical or physical means to suck in liquid.

2. Scope of application: The suction pump is suitable for suction and delivery of low viscosity liquids, such as water, alcohol, etc., while the vacuum pump is suitable for suction and delivery of high viscosity liquids, such as oil, honey, etc.

3. Suction head: The suction head of a suction pump is relatively low, generally not exceeding 8 meters, while the suction head of a vacuum pump can reach tens or even hundreds of meters.

4. Structure: The suction pump usually adopts the structure of a centrifugal pump, while vacuum pumps have various structures, such as rotary vane, liquid ring, root, etc.

5. Usage: The suction pump is suitable for household, agricultural, industrial and other fields, while the vacuum pump is mainly used in industries such as chemical, pharmaceutical, and food.

 

How to choose the capacity of a Mini Vacuum Pump for a breast pump?

When choosing the capacity of a mini vacuum pump for a breast pump, the following factors need to be considered:

1. Frequency of use: If you need to use the breast pump frequently, it may be more appropriate to choose a larger capacity vacuum pump, as this can ensure that the breast pump has sufficient suction to extract milk. On the contrary, if you only occasionally use a breast pump, choosing a smaller capacity vacuum pump may be more cost-effective.

2. Milk volume: If your milk volume is large, you need to choose a vacuum pump with a larger capacity to ensure that the breast pump can quickly extract milk. On the contrary, if your milk volume is small, choosing a smaller capacity vacuum pump may be more appropriate.

3. Portability: If you need to frequently carry a breast pump out, choosing a mini vacuum pump may be more convenient. This type of vacuum pump is usually small and lightweight, and can be easily placed in a backpack or handbag, making it convenient for you to use anytime when going out.

4. Noise: If you want to stay quiet while using a breast pump, choosing a vacuum pump with lower noise may be more suitable. This type of vacuum pump usually adopts advanced noise reduction technology, which can reduce the generation of noise while ensuring suction.
