Hey there! As a supplier of borehole solar water pumps, I've seen my fair share of issues that customers run into. These pumps are super handy, using solar power to draw water from boreholes, but like any piece of equipment, they can have their problems. In this blog, I'll walk you through how to troubleshoot some common problems with a borehole solar water pump.
1. Pump Not Starting
One of the most frustrating things is when you turn on the pump, and nothing happens. There are a few things you can check.
Check the Solar Panel
The solar panel is the power source for your pump. First, make sure it's clean. Dirt, dust, and debris can block sunlight and reduce the panel's efficiency. If it's dirty, give it a gentle wash with a soft cloth and some water.
Also, check the orientation of the solar panel. It should be facing the sun as directly as possible. In the Northern Hemisphere, panels usually face south, and in the Southern Hemisphere, they face north. If it's not properly oriented, adjust it so it gets maximum sunlight.
Another thing to look at is the wiring between the solar panel and the pump. Loose or damaged wires can prevent the power from reaching the pump. Check for any visible signs of damage, like frayed wires or loose connections. If you find any issues, you might need to replace the wires or tighten the connections.
Check the Controller
The pump controller regulates the power from the solar panel to the pump. It could be malfunctioning. Look for any error codes on the controller's display. Different controllers have different error codes, so refer to the user manual to understand what they mean.
If there are no error codes, try resetting the controller. Sometimes, a simple reset can fix minor glitches. You can usually do this by turning off the controller, waiting a few seconds, and then turning it back on.
Check the Pump Itself
The pump might be jammed or damaged. First, make sure there's enough water in the borehole. If the water level is too low, the pump might not be able to start. You can use a water level indicator to check the water level.
If there's enough water, the pump could be blocked by debris. Some pumps have a filter to prevent debris from entering, but it can get clogged. Check the filter and clean it if necessary. You can also try manually rotating the pump shaft (if it's accessible) to see if it's stuck. If it's stuck, you might need to disassemble the pump and remove the blockage.
2. Low Water Output
If your pump is running, but the water output is lower than usual, there are a few possible causes.
Check the Borehole
The borehole could be the problem. Over time, sediment can build up in the borehole, reducing the water flow. You can try flushing the borehole. This involves pumping water into the borehole at a high pressure to dislodge the sediment. You might need to hire a professional to do this if you're not experienced.
The borehole could also be running dry. Check the water level regularly to make sure it's not dropping too low. If the water level is consistently low, you might need to drill a deeper borehole or find an alternative water source.
Check the Pump Impeller
The impeller is the part of the pump that moves the water. It can get worn out or damaged, reducing its efficiency. If the impeller is damaged, you'll need to replace it. You can usually find replacement impellers for your specific pump model.
Check the Pipework
The pipes carrying the water from the pump to the outlet could be blocked or leaking. Check for any visible signs of blockage, like kinks in the pipes or debris inside. If you find a blockage, you can try to clear it using a pipe cleaner or by flushing the pipes with water.
Leaks in the pipes can also cause a loss of water pressure. Look for any wet spots or drips around the pipes. If you find a leak, you can patch it using a pipe repair kit.
3. Strange Noises
If your pump is making strange noises, it's a sign that something might be wrong.
Check for Loose Parts
Loose parts inside the pump can cause rattling or vibrating noises. Turn off the pump and check for any loose screws, bolts, or other components. Tighten them if necessary.
Check for Cavitation
Cavitation is a common problem in pumps. It occurs when the pressure in the pump drops too low, causing the water to form bubbles. When these bubbles collapse, they create a loud noise and can damage the pump. Cavitation can be caused by a low water level, a clogged filter, or a malfunctioning impeller.
To fix cavitation, make sure there's enough water in the borehole, clean the filter, and check the impeller for damage. You might also need to adjust the pump's operating parameters to prevent the pressure from dropping too low.
4. Overheating
If your pump is overheating, it can cause serious damage.
Check the Cooling System
Some pumps have a cooling system to prevent overheating. Check if it's working properly. If the pump has a cooling fan, make sure it's running. If it's not, the fan might be damaged and need to be replaced.
Check the Load
If the pump is working too hard, it can overheat. Make sure the pump is the right size for your borehole and water requirements. If it's too small, it will have to work harder to pump the same amount of water. If it's too big, it might not be operating efficiently. You can consult with a professional to determine the right pump size for your needs.
5. Electrical Problems
Electrical problems can be dangerous, so be careful when dealing with them.
Check the Fuses
Fuses are designed to protect the pump from electrical surges. If a fuse blows, the pump will stop working. Check the fuse box for any blown fuses. If you find a blown fuse, replace it with a new one of the same rating.
Check the Grounding
Proper grounding is essential for the safety of the pump and the people using it. Check the grounding wire to make sure it's properly connected. If it's loose or damaged, it could cause electrical problems or even pose a safety hazard.
