To minimize equipment failures, it is essential to install protective devices for corrosion-resistant submersible pumps. These devices include motor water leakage protection, junction box water immersion protection, insulation resistance protection, winding overheating protection, and bearing overheating protection. However, their installation depends on specific circumstances and may not be necessary for every device. In some cases, special protection devices such as explosion-proof devices may need to be installed.
Apart from installing protective devices, it is crucial to ensure their correct usage for optimal equipment operation. Shenyang well pump manufacturers emphasize the importance of understanding and following proper usage guidelines. This will significantly benefit the overall performance of the equipment and prevent unnecessary failures.
1. Inspection of power supply and wires
Due to the long length of the low-voltage power supply line, it is a common occurrence for the voltage at the end of the line to drop too low. This can cause inconvenience during start-up and operation, as it fails to meet the necessary requirements. It is crucial for the operator of the submersible pump to constantly monitor the voltage supplied. If the voltage falls below 10% of the rated value or exceeds 10% above the rated value, it is essential to halt the motor and investigate the cause in order to rectify the fault.
2. Do some necessary checks before the pump runs
When using a submersible pump, there are several things that you should keep in mind to ensure it functions properly. Firstly, observe the rotation of the pump shaft and ensure it is normal without any sticking. Also, check that the impeller is in the correct position and that the cables and cable plugs are not damaged.
It is also important to keep an eye on the voltage levels during operation and ensure they remain within ±5% of the rated voltage. The positioning of the submersible pump in the water is crucial as well. It should be placed in an area with adequate water supply, free from silt and debris, and hung vertically to prevent any blockages.
If the pump inlet becomes clogged, the water output may decrease significantly, or the pump may even stop functioning completely. Therefore, ensuring proper usage and maintenance of the submersible pump is essential.
3. Avoid frequent switching
Frequent switching on and off of submersible pumps can cause backflow when the electric pump stops. This can lead to excessive starting currents and the burning out of motor windings, which can be detrimental to the equipment. It is crucial to avoid overloading the submersible pump to prevent unnecessary damage to the motor. Therefore, it is essential to handle submersible pumps with care, ensuring optimal performance and longevity.
4. You can enjoy a relatively maintenance-free experience for a prolonged period of time.
To prevent any damage caused by freezing temperatures, it is important to lift the submersible pump out of the pool if it is not going to be used for an extended period of time, especially during winter. Additionally, make sure to drain any accumulated water in the pump before removing it. Store the pump in a dry location to maintain its condition. To prevent rusting, consider applying butter to the key components and lubricating oil to the bearings. Lastly, if the pump is left unused for a long duration, it is advisable to run it for a while periodically to prevent potential part failures.
