cooling fan 12v dc electric submersible water pump

A Mini Submersible Pump works by utilizing a direct current (DC) power source to drive a small motor, which in turn drives the impeller of the pump. The impeller is a rotating component with curved blades that creates centrifugal force when it spins.

When the pump is submerged in water, the impeller rotates, drawing water into the pump through an inlet. As the impeller spins, it pushes the water towards the outlet of the pump, creating pressure and forcing the water to flow out.

The pump is typically connected to a power source, such as a battery, which provides the necessary DC voltage and current to operate the motor. The power source is connected to the motor, which converts the electrical energy into mechanical energy, causing the impeller to rotate.

The speed and flow rate of the pump can be controlled by adjusting the voltage or current supplied to the motor. This allows for customization based on the specific requirements of the application.

Technical Specification

What is the role of the static head of a micro submersible pump in a cooling fan?

In the cooling fan, the static head of the 1.5 inch submersible pump mainly plays the following roles:

1. Determine the head of the water pump: The static head is the head measured by the micro submersible pump when there is no fluid flowing through it. It can be used to determine the head of the water pump to understand the performance and operating status of the water pump.

2. Evaluate the efficiency of the water pump: Comparing the static head and the dynamic head (the head when the fluid flows through the pump) can calculate the energy loss and efficiency of the water pump. By understanding the efficiency of a water pump, you can better select and use a water pump.

3. Detect and solve problems in time: If the water pump fails or its performance decreases, the change in static head can detect and solve the problem in time. For example, if the static head is significantly reduced, it may be due to problems such as internal leakage or blockage of the water pump, and timely measures need to be taken to repair or replace it.

4. Calculate the heat dissipation effect of the cooling fan: The micro submersible pump plays a role in driving the water flow in the cooling fan, and the static head can be used to calculate the speed and flow rate of the water flow to understand the heat dissipation effect of the cooling fan. By adjusting the static head of the micro submersible pump, the speed and flow rate of the water flow can be controlled to achieve better heat dissipation.

How is the static head of a micro submersible pump defined?

The static lift of a micro DC Submersible Pump refers to the lift or total lift of the water pump when there is no fluid flowing through it. Static head is one of the important indicators of water pump performance. It reflects the head or total head of the water pump when there is no fluid flowing through it. It can be used to evaluate the performance and efficiency of the water pump.

Static head can be calculated by measuring the water level of the pump when there is no fluid flowing through it. At static head, there is no fluid flow inside the pump, so there is no friction loss or other form of energy loss. Therefore, the static head can accurately reflect the performance and efficiency of the water pump.

It should be noted that the static head of a miniature submersible pump is not fixed and will be affected by a variety of factors, such as the structure, materials, and manufacturing processes of the water pump. Therefore, when selecting and using a micro submersible pump, it is necessary to consider the actual situation comprehensively.

How to increase the head of a micro submersible pump in a cooling fan?

There are many ways to increase the lift of a micro submersible pump in a cooling fan. The following four methods are provided:

1. Adjust the impeller diameter. According to the principle of a submersible pump, the larger the diameter of the impeller, the greater the pressure difference generated when the water flows through, and the lift will also increase. Therefore, by replacing the new impeller with a larger diameter, the lift of the submersible pump can be effectively increased. However, it should be noted that when replacing the impeller, a new impeller of the same size as the original impeller should be selected, otherwise the stability and durability of the submersible pump may be affected.

2. Reduce pipeline resistance. Reducing pipeline resistance can also increase the head of the submersible pump. Check whether the pipeline is blocked, bent, or discounted. If so, the pipeline should be corrected or replaced.

3. Increase the voltage. As the voltage increases, the pump speed will increase accordingly, thereby increasing the head. However, it should be noted that increasing the voltage may increase the load on the motor and should be operated with caution.

4. Replace the high-lift water pump. If none of the above methods can increase the head of the submersible pump, you can consider replacing the pump with a higher head. When purchasing a water pump, you can consult the manufacturer or seller to learn more about the high-lift water pump models and performance suitable for cooling fans.
