Converting a Submersible Motor to an Overhead Motor in a DC Solar Pump System

When it comes to pumping water, the decision to switch from a submersible motor to a non-submersible motor involves careful planning and execution to ensure reliability and effectiveness. This article discusses the necessary steps to convert a 5 HP DC solar pump from a submersible motor to a non-submersible 5 HP Falcon motor, along with best practices to manage environmental conditions and mechanical mounts.

Understanding the Current System and Requirements

A DC solar pump typically relies on a submersible motor to efficiently pump water from a well. However, if you're considering a switch to a non-submersible motor, such as a 5 HP Falcon motor, there are several factors to consider. These include the existing mechanical setup, the environmental conditions, and the new mounting requirements for the non-submersible motor.

Choosing the Right Conversion Method

Two primary methods to install a non-submersible motor in a DC solar pump include:

Constructing a Mechanical Mount: The first method involves designing and building a reliable and sturdy mechanical mount to securely position the motor over the well. This mount must be robust enough to withstand the forces exerted during operation, while also considering the extraction process. Swam Dry Mounting: Alternatively, another method is to modify the pump setup so that the motor does not come into contact with water. Strategies include ensuring the motor is placed above the water level, sealed properly, and equipped with a reliable switch to control its operation.

Designing and Building a Mechanical Mount

When constructing a mechanical mount, the focus is on creating a stable, robust, and water-resistant structure that can support the weight and operational forces of the motor. Here are the key steps to follow:

Material Selection: Use appropriate materials, such as stainless steel, galvanized steel, or other corrosion-resistant metals, especially if the environment involves frequent exposure to water or damp conditions. Mount Design: Develop a design that ensures the motor is securely fastened and can withstand fluctuations in water pressure. Consider the use of gasket seals and tensioning mechanisms to prevent water ingress. Support Structure: The mount should be well-anchored to the well structure to prevent any movement during operation. Use heavy-duty brackets and secure fittings to ensure stability.

Ensuring Environmental Conditions are Managed Properly

Even with a mechanical mount, it's crucial to manage the environmental conditions to ensure the motor's longevity and effectiveness. Consider the following:

Water Temperature: Monitor the water temperature to ensure it does not rise too high, which can affect the motor's performance and lifespan. Dirt and Debris: Regularly clean the well to prevent dirt, debris, and other contaminants from entering the pump and causing damage. Circulation of Air: Maintain proper air circulation within the well to prevent moisture build-up and potential electrical hazards.

Selecting the Right Motor for the Job

Prior to switching to the 5 HP Falcon motor, it's essential to ensure that it is the right fit for your pump system. Once you have chosen the motor, follow these steps:

Check Compatibility: Verify that the motor size, voltage, and power requirements align with your existing pump system. Install the Switch: Integrate a reliable switch to control the motor's operation, ensuring that it can turn on and off as needed without hesitation. Trial Installation: Before finalizing the installation, perform a trial run to check for any issues or unexpected behavior.

Conclusion

Converting from a submersible motor to a non-submersible motor in a DC solar pump system requires careful planning and execution. By constructing a mechanical mount and ensuring proper environmental conditions, you can maintain the reliability and effectiveness of your water pumping system. Always prioritize safety and reliability to ensure that your system continues to function efficiently and effectively over time.
