High Pressure DC Electric Submersible Water Pump

How is the waterproof performance of the Micro Submersible Pump achieved?

First of all, a mechanical seal is used between the motor and the casing of the Submersible Pump. This sealing method separates the rotating parts and the stationary parts, and uses a sealing ring to form a double seal, which effectively prevents medium leakage.

Secondly, dynamic and static seals are also used inside the casing of the submersible pump. This sealing method installs O-rings on the stationary parts and ensures that the distance between the rotating parts and the stationary parts is small enough, thus effectively preventing medium leakage. . In addition, a diaphragm seal is used between the motor and the casing of the submersible pump. This sealing method achieves waterproof and anti-corrosion effects by dividing the pump body into two air chambers and using a diaphragm to separate the inside and outside of the pump body.

How to determine the stability of the Mini Submersible Pump when using a 33cm head to measure flow?

1. Observe the operating status of the pump: Observe the sound, vibration, temperature and other parameters of the pump during operation. If the pump runs smoothly without abnormal sound, vibration and temperature changes, it means that the stability of the pump is good.

2. Measure flow and head: Under the same working conditions, measure the flow and head when using 33cm head and standard head respectively. If the flow rate and head when using 33cm head are not much different from the flow rate and head when using standard head, it means that The stability of the pump is better.

3. Check all parts of the pump: Check all parts of the pump, including motors, bearings, seals, etc. If all parts are in good working condition, the stability of the pump is good.

4. Test the reliability of the pump: Observe the operating status and performance changes of the pump through long-term operation or extreme tests such as pressure and temperature. If the pump does not fail or performance declines during long-term operation or extreme tests, it means that the pump is reliable. Better stability.

How to solve the problem when the Miniature Submersible Pump is not working

1. Check the power supply: First check whether the power supply is normal, whether the power plug is loose, whether the power cord is disconnected, etc. If there is a power problem, it needs to be dealt with in time to ensure that the power supply is normal.

2. Check the motor: If the power supply is normal, then check whether the motor is damaged or malfunctioning. The motor is a key component of the micro submersible pump. If the motor is damaged or malfunctions, the pump will not work properly. If there is a problem with the motor, it needs to be replaced with a new one.

3. Check the pump body: If the motor is normal, then check whether the pump body is blocked. If the inlet and outlet of the pump are blocked by debris, the pump will not work properly. At this time, the blockage needs to be cleared, such as sand, soil or other solid materials.

4. Check the water level: The Small Submersible Pump needs to operate under a certain water depth. If the water level is insufficient, the pump will not start normally. At this time, you need to confirm whether the water level meets the requirements of the pump. If the water level is not enough, you need to add enough water.

5. Seek professional help: If the above methods still cannot solve the problem, it is recommended to contact after-sales service personnel or professional maintenance personnel for repair.

How to prevent micro DC Submersible Pump failures？

Prevent overload operation

Overload operation is one of the common causes of micro submersible pump failure. During operation, avoid overload operation, long-term continuous operation or frequent startup. At the same time, the operating parameters of the pump should be adjusted according to actual needs to avoid damage to the pump due to overload operation.

Keep water clean

Water cleanliness is an important condition for the normal operation of Mini Pumps. It is necessary to keep the water source clean and sufficient to avoid clogging and wear of the pump caused by impurities, sediment and other substances in the water. At the same time, the inlet and outlet of the pump and the filter should be cleaned regularly to ensure clean water quality.

Install anti-leakage devices

The anti-leakage device is an important guarantee for the safe operation of the micro submersible pump. During installation and use, installation and use must be carried out in accordance with the instructions or installation guide provided by the manufacturer to ensure the normal operation of the anti-leakage device. At the same time, it is necessary to regularly check the working status of the anti-leakage device to discover and solve problems in a timely manner.

Avoid prolonged outages

Prolonged outage will cause corrosion and aging of the internal components of the micro electric submersible pump, thereby increasing the risk of failure. Therefore, we should try to avoid long-term outage, and perform appropriate maintenance during the outage period to keep the pump in good condition.

Pay attention to waterproof measures

Waterproof measures are an important guarantee for the normal operation of micro submersible pumps. During use, avoid water entering the internal parts of the pump to prevent water damage to the pump. At the same time, during installation and use, waterproof measures must be installed and used in accordance with the instructions or installation guide provided by the manufacturer.

How is the life of a micro submersible pump affected by water quality?

1. Corrosiveness: Chemical substances in water, such as acids, alkalis, salts, etc., will corrode the metal parts of the micro submersible pump, causing damage to the parts and thus affecting the service life of the pump.

2. Scaling: Suspended solids, minerals, etc. in the water quality will form scaling on the surface of the components of the micro submersible pump, increasing friction resistance, affecting the normal operation of the pump, and even causing the pump to get stuck or damaged.

3. Wear: Impurities in the water will cause wear to the seals, bearings and other components of the DC Pump , resulting in reduced sealing performance and increased leakage, thus affecting the service life of the pump.
