Here are some common issues you can face with an irrigation pump. These problems can include: Less water than usual, leaky suction pipe, out-of-adjustment impellers, and blockages in the impeller. If any of these problems sound familiar, you should check with a qualified irrigation professional. Listed below are some ways to solve these common problems.
Less water in the pump
The reason why there is less water in the pump is due to a number of reasons. One reason is that the water pump is not operating at its optimal level due to a clogged or damaged intake line. Some people have even attached a smaller diameter intake line than the pump’s specifications call for. The pump will not function properly if the intake line is crimped or “sucked in.” This can also be caused by the size of the hose used with the irrigation pump.
Another reason why irrigation pumps struggle is due to high suction lift. When lake levels fall and the pump is not able to draw water, the suction lift becomes too high. Calculating the suction lift involves taking into consideration the friction losses in the intake piping and foot valve. High suction lift can result in pump noise and can even cause cavitation. This can ruin the internal components of the pump.
Leaking suction pipe
When the pump fails to suction, it may be due to a leak in the suction pipe. There are several causes of this problem, including a broken suction pipe, valve that is not open, clogs in the strainer, and damaged seals and cases. In addition, you should watch for suction surges, which are cycles of water flowing through the pump. To diagnose the cause of a leaking suction pipe, check the motor, if it is dual voltage, and if it is single voltage, connect the pump to the same voltage.
Another reason your pump is leaking is due to water freezing in the pump’s priming chamber. Water freezes and expands in the pump when the ambient temperature drops below freezing. This results in cracking and a costly replacement. Fortunately, you can often drain and reheat the pump without any loss of function. Alternatively, you can call a professional irrigation pump repair service to fix the problem. If you don’t want to spend the money to replace the pump, consider the cost of a replacement.
Out of adjustment impellers
Out of adjustment impellers are the cause of many common problems with irrigation pumps. They can reduce discharge, create cavitation, or cause sand pumping. If your impellers are out of adjustment, you will likely need to replace the entire pump bowl assembly. If you have experienced this problem before, you should consider contacting a pump repair expert to make an adjustment. Read on to learn more about how to make an impeller adjustment for your irrigation pump.
First, check the height of the impellers. Some pumps have an absolute lift capacity of over 20 feet. The actual lift is much lower than the theoretical value because atmospheric pressure must be added to water pressure. This means that every foot of water above the eye of the impeller increases the pressure. Consequently, it will take about 0.4 psi to lift water over 20 feet. Therefore, check the height of the pump from top to bottom to ensure that everything is in proper alignment.
Blockages in the impeller
The impeller of irrigation pumps can become blocked because of outdoor debris. Debris will clog the foot valve and reduce the amount of water that the pump can deliver. Small particles may also become trapped in the vanes of the impeller, reducing the pump’s performance. Here are some tips to prevent blockages. Once a blockage is detected, it should be easily removed with a screwdriver.
– Check the intake line: The inlet pipe should have the correct diameter. It must be no less than two feet in diameter. Avoid fitting elbows, tees, or check valves on the pipe. Too much flow or too little back-pressure will cause air pockets. A proper discharge line will allow the pump to maintain its optimal flow rate. If you are unsure about the right size of the inlet line, check the manufacturer’s guidelines for use.
Overloading the pump
There are several causes of this problem. The pump’s impeller may be clogged with sand, which can cause an overload. Sand can also bind the pump’s motor, which can cause amp readings up to six times the normal level. In addition to overloading, sand can damage the pump’s internal components and connected equipment, resulting in reduced efficiency and shortened service life.
Incorrect selection of the power unit is another common reason for low efficiency. When purchasing an irrigation pump, you should consult the vendor and carefully read installation instructions. If it’s an electrical pump, you can ask the vendor to perform a field evaluation. If you’re using an internal combustion engine, however, this can be more difficult to test. Private consultants and irrigation pump suppliers can do this for you.
If you have a domestic water booster pump, you have likely experienced some of the common problems with irrigation pumps problems with the impeller or foot valve. You’ve likely also experienced issues with the oil-lubricated pump, suction pipe, and mechanical shaft seal. If none of these problems were the cause of your pump’s malfunction, here are some simple ways to fix it.
Follow these steps to prevent further damage to your pump. If you suspect a problem with your pump, contact a qualified irrigation technician.
Foot valve or impeller blockage
One of the most common problems is a blockage when a pump fails to perform. Outdoor debris can collect on the intake screen in the foot valve, restricting the water delivered by the pump. Likewise, smaller particles may be lodged in the impeller vanes, decreasing pump performance. A simple fix for a blocked impeller is to clean it with a garden hose and replace the foot valve and impeller.
Debris blockage
One of the most common irrigation pump problems is a buildup of debris. Debris can clog up the pump, whether it’s in the water supply line or in the re-circulating port. The pump’s pressure can also be affected by a leak elsewhere. A leaking water line can cause the pressure to drop rapidly, regardless of whether the pump is used.
Oil-lubricated pumps
Most farmers face similar problems with their irrigation pumps. These pumps require frequent maintenance. In addition to checking the oil, it is also essential to adjust the turbine pump’s lateral adjustment according to the manufacturer’s recommendations. Overload, low voltage, and low frequency in the lines can decrease the motor speed and cause pump lockup. Additionally, water loss can lead to bearing failure. Oil-lubricated pumps should be checked for these issues as soon as possible.
Suction pipe issues
If you notice that your irrigation pump is not sucking water, there are many possible causes. Incorrect piping can prevent the pump from working correctly. To avoid this problem, make sure your pipework is at least double the diameter of the pump’s flange and straight. Your pipework must also be set to a voltage your pump was designed to accept, and the suction pipe should never be narrower than the suction port.
