Submersible electric pumps have a multitude of uses, particularly in deep wells, where the entire unit is submerged in water while in operation. These types of pumps are invaluable in extracting groundwater for domestic use, agricultural irrigation, mine rescue, industrial cooling, and a variety of other applications. Their versatility is such that they can even be employed in fountain scenes or water lifting projects in rivers, reservoirs, canals, and other waterways. Without submersible electric pumps, many of these activities would be nearly impossible, underscoring the importance of these high-tech devices in modern society.
1. Grounding is required
To ensure personal safety during the use of submersible pumps, it is mandatory to adopt maintenance grounding as a national standard. Neglecting maintenance grounding can lead to dire consequences as the pump's casing may leak electricity, resulting in a charged water outlet and surface of the pumped water. These scenarios pose a threat to the user's safety and also lead to a substantial loss of electricity. Therefore, adherence to maintenance grounding is paramount.
2. Install the leakage protector
The operation of Shenyang submersible pumps in water poses a risk of electricity leakage, which can lead to power loss and even electric shock incidents. To prevent this, the installation of a leakage protector is essential. When the leakage value of the submersible pump exceeds the operating current value set for the leakage protector, it automatically shuts off the power supply to ensure safety.
3, the power supply voltage is normal to start
Maintaining the correct voltage is crucial to the proper functioning and longevity of submersible pumps. When the voltage is either too high or too low, the temperature of the pump can rise too high and potentially destroy the machine. This is a common issue in rural areas due to long low-voltage power lines. In these cases, it is essential for the operator to regularly check the power supply voltage. If the voltage is less than 10% of the additional voltage, more than 10% higher than the additional voltage or the current is greater than 20% of the additional current, it is essential to shut down the pump and avoid starting it until the power supply voltage returns to normal. Accurately monitoring the voltage supply is key to preventing damage and ensuring the longevity of the submersible pump.
4, can not overload operation
To prevent the submersible electric pump from overloading for an extended period, it is important to adhere to certain precautions. Firstly, avoid using the low-lift pump for high-lift operations as it can lead to overload. Additionally, it is advisable not to pump water with a high sand content, as this can result in heavy mud, further increasing the risk of overload. It is crucial to continuously monitor the current value and ensure it remains within the permissible limits defined by the rules. Should the current exceed these limits, it is imperative to stop the pump immediately and conduct a thorough inspection to identify the cause of the excessive current.
5. Do not switch frequently
It is important to avoid frequent starting of the submersible electric pump, as it can lead to backflow when the pump is stopped. Starting the submersible pump immediately can put a heavy load on the motor, causing excessive starting current. Therefore, it is advised to avoid abrupt starting and allow a sufficient amount of time for the pump to rest before operating it again. This will not only prevent motor damage but also ensure safe and efficient usage of the submersible electric pump.
6. Avoid using in silt environment
To avoid damaging the submersible pump's motor windings due to poor heat dissipation, it's critical not to use the pump in muddy environments where it might sink into the mud. As such, before launching the submersible pump, ensure that you remove any sludge or debris from its operating environment. Also, note that if the motor generates too much heat and the water isn't flowing smoothly, it's time to shut off the pump and address the issue to prevent further damage.
7. Take protective measures after deactivation
To prevent corrosion and ensure the submersible pump starts successfully, it is important not to leave it unused for long periods of time after it has been lowered into the well. Instead, the deactivated pump should be taken out of the water and turned on for a few minutes once a week. This regular operation helps prevent the build-up of corrosive elements. Moreover, when the pump remains unused for an extended period, it should be run in clean water for a few minutes to remove any mud and debris that may have accumulated inside or outside the pump.
After this initial cleaning, the pump should be allowed to dry on the water surface before undergoing a comprehensive inspection. It is recommended to disassemble all the parts for thorough maintenance, including scrubbing, rust removal, and descaling. Additionally, any worn-out components must be replaced before reassembling the pump. To prevent rust, it is advisable to apply a coat of paint. Finally, store the pump in a dry and non-corrosive gas warehouse for safekeeping. By following these maintenance steps, the submersible pump can be preserved and kept in optimal working condition.
