Micro Small Submersible Water Pump For Fountain

What is the difference between a micro DC Diaphragm Water Pump and a Micro Submersible Pump?

Micro diaphragm water pump:

1. Working principle: Micro diaphragm water pumps usually use diaphragms to pump liquids. A diaphragm is a flexible diaphragm that moves back and forth within the pump body, pumping fluid by changing its volume. When the diaphragm moves forward, it will push the liquid into the outlet pipeline; When it moves backwards, the liquid is sucked in from the inlet pipeline.

2. Features:

Self suction capacity: Due to the design of the diaphragm, micro diaphragm water pumps usually have good self suction capacity, which can start and extract liquid without external assistance.

·Low noise: Due to the flexible movement of the diaphragm and the commonly used silent design, this pump operates with relatively low noise.

·Low maintenance: Diaphragm Pumps usually have a relatively simple structure and fewer worn parts, so maintenance requirements are low.

Application limitations: Due to the structure and working principle of diaphragm pumps, they are usually not suitable for high-pressure or high temperature environments.

Micro Submersible Pump:

1. Working principle: Micro submersible pumps usually use centrifugal or mixed flow working principles. There is one or more impellers inside the pump body. When the motor drives the impeller to rotate, the liquid is pushed outside the pump body under the action of centrifugal force, thereby achieving pumping.

2. Features:

·High flow rate: Micro submersible pumps are typically designed to provide high flow rates and are suitable for applications that require rapid drainage or the transportation of large amounts of fluid.

·Underwater work: The submersible pump is designed to work completely submerged in water, without the need for additional inlet pipes or installation positions.

What are the parameters of a Mini Submersible Pump?

The parameters of micro submersible pumps mainly include the following aspects:

1. Flow rate (Q): The definition of flow rate is the volume of liquid discharged by the pump outlet per unit of time, usually measured in cubic meters per hour (m */h) or cubic meters per second (m) ³/ s) In units. For submersible pumps, special attention should be paid to the selection of flow rate to ensure that the flow rate of the submersible pump in the well water is less than or equal to the water inflow in the well, in order to prevent the water in the well from being drained and causing the motor to burn out.

2. Head (H): Head refers to the energy obtained by a unit weight of liquid after passing through a pump, which is the height of the liquid column after being pumped, usually measured in meters (m). When selecting the head of a submersible pump, factors such as pipeline length, number of bends, and pipe wall roughness need to be considered, all of which can affect the loss of head. It is generally recommended to increase the head margin by 5% to cope with the actual situation.

3. Speed (n): Speed refers to the number of revolutions per unit time of the pump shaft, usually measured in revolutions per minute (r/min). The choice of rotational speed depends on the performance and application scenarios of the motor.

4. Power and efficiency: Power is a physical quantity that describes the work done by a pump per unit of time, and effective power (PU) refers to the effective energy obtained by the liquid conveyed by the pump, also known as output power. Shaft power (Pa) refers to the power transmitted from the prime mover to the pump shaft, also known as input power. The efficiency of a pump (n) is defined as the ratio of effective power to shaft power. These are important indicators for evaluating pump performance.

Can a Miniature Submersible Pump with a waterproof rating of IPX8 be completely submerged underwater?

Under the IPX8 waterproof rating standard, the submersible pump can operate at a depth of 3 meters underwater and will not be affected by water erosion.

This means that micro submersible pumps with a waterproof rating of IPX8 can be completely submerged underwater.

However, for specific products, in addition to waterproof grade, their usage instructions and specification parameters are also very important reference basis. because

When using a DC Submersible Pump with a waterproof rating of IPX8, it is best to first read its user manual and specification parameters in detail to ensure that

Proper use and safety.

In addition, any electronic product poses certain risks when used in water, so when using a miniature submersible pump with a waterproof rating of IPX8

When doing so, it is also important to pay attention to safety and avoid excessive soaking or damage.

What is the relationship between the flow rate and power of a Small Submersible Pump?

There is a certain relationship between the flow rate and power of micro submersible pumps.

Flow rate refers to the volume of liquid passing through pipelines or pumps per unit time, usually expressed in liters per minute (L/min) or cubic meters per hour (m ³/ h) Represent. Power refers to the work done by a water pump per unit of time, usually measured in kilowatts (kw).

In theory, there is not a simple linear relationship between the flow rate and power of a micro submersible pump. As the flow rate increases, the required power also increases. This is because as the water flow increases, the water pump needs to withstand a greater load, thus requiring more energy to drive the water pump to work. However, when the flow rate increases to a certain extent, the efficiency of the water pump may begin to decrease, and even with an increase in power, the increase in flow rate will become less significant.

To describe the relationship between flow and power, empirical formulas or graphs can usually be used. These formulas or graphs can be derived based on specific pump design and operating conditions to predict the required power at a given flow rate, or vice versa.
