Product details

The DYX DQB020-A mini air pump be operated with a DC 3V voltage. It has a current rating of less than 350mA, ensuring efficient power consumption.

This DC3.0V mini air pump has a low flow rate of 0.4L/Min, making it suitable for applications that require a controlled and precise airflow.The pump is highly durable, with a lifespan of over 100,000 cycles and use in household smart sweeping machines, where it can provide the necessary air circulation for efficient cleaning.

The principle of a mini diaphragm pump is based on the movement of a flexible diaphragm to create changes in pressure within a closed chamber, which in turn, pumps air or gas. Here's a detailed description of the principle of operation:

A mini diaphragm air pump is a type of pump used to move air or gases in various applications. It operates using a diaphragm, which is a flexible membrane that moves back and forth to create a pumping action. These pumps are often compact and lightweight, making them suitable for portable and low-flow applications. Here is a basic structure of a mini diaphragm air pump:

Diaphragm: The heart of the pump is the diaphragm, which is typically made of a flexible material such as rubber or elastomer. This diaphragm moves back and forth to create a pumping action.
Inlet Valve: The diaphragm air pump has an inlet valve that allows air or gas to enter the pump chamber during the expansion phase of the diaphragm's movement. This valve opens when the diaphragm moves away from the pump chamber.
Outlet Valve: On the opposite side of the diaphragm chamber, there is an outlet valve. This valve opens when the diaphragm moves toward the pump chamber, forcing air or gas out of the pump.
Pump Chamber: The pump chamber is the space where the diaphragm moves back and forth. It is sealed to create a closed system. As the diaphragm moves, it changes the volume of this chamber, causing the pressure to change, which in turn moves the air or gas.
Drive Mechanism: Mini diaphragm air pumps are typically driven by a mechanism such as an electric motor or a piezoelectric actuator. This mechanism provides the energy needed to move the diaphragm.
Housing: The pump is enclosed in a housing or casing, which protects the internal components and may also have ports or connectors for attaching tubing or other components.
Check Valves: Check valves are often used at the inlet and outlet ports to ensure that air or gas flows in the desired direction. They prevent backflow and help maintain the one-way flow of the diaphragm pump.
Tubing or Connectors: Tubing or connectors are attached to the inlet and outlet ports of the pump to direct the flow of air or gas to and from the desired locations.
Mounting and Base: The pump may have a mounting system or a base for easy installation and stability.

The pump flowrate-pressure performance curve, often referred to as the pump curve, is a graphical representation of how a pump's flow rate (Q) and pressure head (H) relate to each other under varying operating conditions. This curve is a fundamental tool for understanding and selecting pumps for specific applications, and it provides critical information about a pump's performance characteristics.

Pump&Valve Application

Mini diaphragm air pumps are versatile and find use in a wide range of applications, including medical devices, analytical instruments, environmental monitoring, and more, where precise control of air or gas flow is necessary. The design may vary depending on the specific requirements of the application.

FAQ

Q: What is a mini diaphragm pump, and how does it work?

A: A mini diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm to move air or fluids. It works by the reciprocating movement of the diaphragm, which creates suction and discharge cycles to move the medium.

Q: What are the advantages of using a mini diaphragm pump?
A: Mini diaphragm pumps are known for their compact size, low power consumption, precise flow control, and ability to handle a wide range of fluids and gases. They are also generally low maintenance.

Q: Are mini diaphragm pumps suitable for continuous operation?
A:Mini diaphragm pumps including mini water pump / mini air pump are often designed for continuous operation. However, the specific model and manufacturer's guidelines should be considered to determine the pump's continuous operation capabilities.

Q:Can mini diaphragm pumps be used for high-pressure applications?
A: Mini diaphragm pumps are generally not designed for high-pressure applications. They are better suited for low to moderate pressure ranges. High-pressure applications typically require specialized pumps.

Q: How do I select the right mini diaphragm pump for my application?
A: Pump selection depends on factors such as required flow rate, pressure, fluid compatibility, temperature, and environmental conditions. Consulting with a pump supplier or manufacturer is often recommended.
