Product details

Small diaphragm air pump is a pump that uses micro DC motors (such as 6V, 12V, 24V motors) as the power driving device. This type of pump drives the internal mechanical eccentric device to perform eccentric motion, causing the internal diaphragm to move back and forth. It can compress and stretch air in a fixed volume pump chamber, forming

Micro positive pressure and negative pressure create a pressure difference between the pump suction port and the external atmospheric pressure. This pressure difference can push gas into the pump chamber and discharge it from the exhaust port.

The membrane air pump has some significant characteristics, such as a medium temperature of up to 60 ℃, allowing dry operation, an internal pressure switch to protect the pump from damage during operation, an internal relief valve to control the normal operation of the pump, convenient disassembly, and the use of safe low voltage to ensure personal safety. In addition, it also has advantages such as small size, low noise, low energy consumption, and long service life

Why can both micro diaphragm water pumps and micro diaphragm air pumps be used in coffee machines? When to choose a water pump and an air pump when applied to a coffee machine?

Both micro diaphragm water pumps and micro diaphragm air pumps can be used in coffee machines, but they have some differences in application.

Micro diaphragm water pumps are commonly used to pump water from the water reservoir to the heating elements of coffee machines. They can provide stable water flow and provide sufficient pressure to push water through the coffee machine's system when needed. Therefore, when a coffee machine needs to prepare coffee by pumping water, it usually chooses to use a mini water pump.

On the other hand, micro diaphragm air pumps are commonly used in steam generation systems in coffee machines. They can generate enough pressure to push air into water, generating steam for making milk froths or heating milk. Therefore, when a coffee machine needs to generate steam, a small dc air pump is usually chosen.

What is the difference in performance between micro diaphragm water pumps and micro diaphragm air pumps?

There are several main differences in performance between micro diaphragm water pumps and micro diaphragm air pumps:

1. Application: The micro water pump is mainly used for conveying liquids, such as water in coffee machines. Micro diaphragm air pumps are mainly used to generate gas flow or create vacuum, such as generating steam in coffee machines or for other applications that require gas drive.

2. Working principle: The working principle of a self priming micro water pump is to drive the eccentric wheel through an electric motor, which in turn drives the diaphragm to move back and forth, thereby changing the volume of the pump chamber and allowing the liquid to be sucked in and discharged. The micro diaphragm air pump drives the diaphragm to move back and forth through an electric motor, forming the suction and discharge of gas.

3. Pressure and flow characteristics: Micro diaphragm water pumps typically have high pressure output and flow rate, making them suitable for situations that require pumping liquids and overcoming certain resistance. The pressure and flow rate of micro diaphragm air pumps are relatively low, mainly used to generate gas flow or form vacuum.

4. Noise and vibration: Due to the need to pump liquid, micro diaphragm water pumps may produce certain levels of noise and vibration during operation. The micro diaphragm air pump, due to its main processing of gas, has relatively low noise and vibration.

What are the specific manifestations of noise and vibration in micro diaphragm water pumps and micro diaphragm air pumps?

1. Noise: Micro diaphragm water pumps may produce certain noises during operation, mainly from the mechanical movement inside the pump body and the impact of water flow. The level of noise depends on the design, manufacturing process, and usage conditions of the pump. Some high-quality water pumps may adopt noise reduction techniques, such as using soundproofing materials or optimizing the pump body structure, to reduce noise levels.

2. Vibration: Micro diaphragm water pumps may generate certain vibrations during operation, mainly from the reciprocating motion of the eccentric wheel and diaphragm inside the pump body. The amplitude and frequency of vibration depend on the design, manufacturing process, and usage conditions of the pump. Vibration may have a certain impact on the pump body and installation foundation, so it is necessary to ensure the stability of the pump body and adopt appropriate shock absorption measures during installation.

Noise and vibration of mini electric air pump:

1. Noise: The noise generated by the dc air pump during operation mainly comes from the impact and vibration during the operation of the motor and gas flow process. Due to the fact that air pumps process gas, their noise level is usually lower than that of water pumps. However, if the design or manufacturing process of the air pump is poor, or the usage conditions are improper, it may lead to an increase in noise levels.

2. Vibration: The vibration of a portable electric air pump mainly comes from the operation of the motor and the reciprocating motion of the diaphragm. Similar to water pumps, the amplitude and frequency of vibration depend on the pump's design, manufacturing process, and usage conditions. To reduce the impact of vibration on the air pump and surrounding environment, appropriate shock absorption measures can be taken, such as using rubber pads or shock absorbers.
