What if the Mini Submersible Pump runs out of water?

If the Submersible Pump runs out of water, the first step is to check if there is a problem with the water source to confirm if it is blocked or if the water level has dropped. If there is no problem with the water source, it is possible that the inlet of the submersible pump is blocked or the internal parts of the pump are damaged, causing the pump to be unable to absorb water.

The solution can include the following steps:

1. Cleaning the water inlet: Check if the water inlet of the submersible pump is blocked by debris. Cleaning the debris at the water inlet can allow the pump to absorb water again.

2. Check the inside of the pump: Open the submersible pump and check if the internal parts of the pump are normal. If any damaged or blocked parts are found, they can be cleaned or replaced.

3. Check the pipeline connection: Check if there is any leakage or looseness at the connection between the submersible pump and the pipeline, and ensure that the connection is well sealed.

4. Add water source: If none of the above methods can solve the problem, you can try adding some water source to the inlet of the submersible pump to help the pump absorb water again.

How to ensure the normal operation of a Micro Submersible Pump when in use?

1. Water level monitoring: Ensure that the water level of the submersible pump does not fall below the pump's water level during operation. A water level monitoring probe or a water pump with built-in anti dry rotation protection function can be used, so that it can be stopped in a timely manner in case of failure.

2. Correct installation depth: Install the submersible pump at the correct depth, which not only prevents dry running but also prevents damage to the pump due to high water pressure. The recommended depth for entering the water is 5 meters below the dynamic water level, but the specific situation may need to be adjusted according to the model and parameters of the submersible pump.

3. Cooling: Ensure that there is sufficient water flow around the submersible pump to provide necessary cooling to prevent the motor from overheating. The optimal space between the pump layer and the drilling wall is at least 10 millimeters, which not only prevents mechanical damage but also improves the cooling effect.

4. Voltage stability: The submersible pump operates within a certain voltage range, and voltage fluctuations in the network may lead to more frequent pump shutdowns and engine damage. Therefore, it is necessary to ensure that the power supply voltage is controlled within ± 5% of the rated voltage.

5. Frequent start and stop: Frequent start and stop of submersible pumps, whether due to insufficient voltage or water shortage, can overload the motor and pump contactor, greatly reducing their service life. Therefore, unnecessary starting and stopping should be avoided.

Why can't the Small Submersible Pump be operated without a pressure tank?

Running a DC Submersible Pump without a pressure tank may encounter the following issues:

1. Unstable water pressure: After the submersible pump draws water, its outlet pipeline will generate a certain amount of water pressure. But if there is no pressure tank for stabilizing, the outlet pressure may be unstable and unbalanced. This can lead to unstable water flow in the water supply system, affecting the water experience.

2. Low efficiency: For scenarios that require long-term pumping, if the water pressure is unstable, the pumping efficiency of the submersible pump will be greatly reduced. This will increase energy consumption and increase operating costs.

3. Equipment loss: When the submersible pump is in operation, the impeller continuously rotates, causing friction loss. If the water pump cannot exhaust normally, additional load will be generated due to the increase in pressure at the beginning of pumping, accelerating the damage of the water pump. After installing the pressure tank, this damage can be reduced, thereby extending the service life of the submersible pump.

What is the pressure tank for the Miniature Submersible Pump？

The pressure tank of a miniature submersible pump is a closed container connected to the water supply pipeline at the bottom. The water in the pipeline enters the container under pressure and occupies the volume of air, forming compressed air until reaching an equilibrium point. The function of a pressure tank is as follows:

When the water pressure rises, water will further squeeze into the pressure tank, thereby avoiding a sudden increase in pressure.

When the water pressure decreases, water will enter the pipeline under the action of air, thereby avoiding a sudden drop in pressure.

3. In larger cans, it can also play a role in balancing flow and storing media. According to the size of the tank, the flow rate of the pipeline liquid, and the installation location, the pressure tank can buffer the pressure and flow fluctuations caused by various reasons in the pipeline.

Technical Specification

Does the micro electric submersible water pump have overheating protection function?

Micro submersible pumps usually have overheating protection function. This function is mainly designed to protect the pump body and motor from prolonged operation or overheating

It will not be damaged under normal conditions. When the temperature of the submersible pump reaches a certain level during operation, the overheat protection mechanism will automatically start and stop the submersible pump

To avoid damage to the pump body and motor due to overheating during operation.

The overheat protection mechanism is a standard feature in pump products today, which is crucial for ensuring the safe and stable operation of submersible pumps and extending their service life. Therefore, when using submersible pumps, users need to be careful to avoid prolonged continuous use to avoid overheating of the pump body.
