What happens when the fish tank pump can t pump water?

You can take out the pump and plug it in for a trial, if it can't be turned, it is recommended to disassemble the pump. The pump used for filtration is still used to pump water outward when changing water. After cleaning the rotor and plugging it in again, if there is no response, then it means that it is broken, according to the pump nameplate.

The information can be repurchased and replaced. When changing the water, it is used to pump water outward, and the water can generally be changed by using a siphon to draw the water out, without the help of too many tools.

The principle of the application of the fish tank pump:

Borrowing atmospheric pressure.

And there is also the phenomenon of siphoning.

Lower the outlet below the surface of the water to continuously suck the water out until the water is finished.

Siphon phenomenon: It is a force phenomenon that uses the height difference of the liquid level to fill a tube structure with an inverted U-shape, and then places the high end of the opening in a container filled with liquid, and the liquid in the container will continue to flow out from the lower position of the opening through the siphon.

The water pump of the fish tank cannot pump water, because the pump itself is faulty, or the pumping equipment is polluted and blocked by impurities such as aquatic plants in the water tank, so at this time it is necessary to conduct a comprehensive inspection of him and replace the faulty part, so that the pump can be used more smoothly.

1.If there is air in the inlet pipe and pump body, it is necessary to immediately check whether it is filled with water, and at the same time see if there is any wear or too loose phenomenon that causes the pump to not pump water;

2.The speed of the water pump is too low, due to the lack of power, can not meet the effect of self-priming, so that there is no pumping situation, if it is not a mechanical failure, it is necessary to change to a higher power pump.

The fish tank pump does not pump water, probably.

1. If there is air in the inlet pipe and pump body, it is necessary to check whether it is filled with water immediately, and at the same time see if there is any wear or too loose phenomenon that causes the pump not to pump water;

2. The speed of the pump is too low, due to the lack of power, it cannot meet the effect of self-priming, so that there is no pumping, if it is not a mechanical failure, it is necessary to change to a pump with higher power;

3. The suction stroke of the pump is relatively large, which exceeds its maximum suction stroke, resulting in its inability to absorb water after working and cannot be used normally.

Solution. 1. Check whether the impeller of the pump is stuck, take it out if there is a foreign object, and then reopen it to give it a try. The pump must be completely immersed in the water, its function is to make the water move, form a flow of water to allow the fish to move better, but also help to maintain the water quality, and at the same time can be convenient filtration.

It should be noted that its power and flow must be appropriate.

2. It may be that the root of the plug is broken or the power cord is broken or the stator coil is broken, for safety, in addition to replacing the plug, it is forbidden to repair it, so as not to cause leakage and hurt people, because the value is not high, generally no one repairs, so if the pump is not pumped after cleaning, it is recommended to replace the new pump.

3. Fish farming first raises water, fish tank pump is very important, without a good water environment, fish are easy to get sick and die. The most important thing is how to create a quiet and comfortable water environment for the fish, and the fish tank submersible pump is indispensable.

The above is the introduction of the fish tank pump does not pump water, I hope it can help you.

First of all, see if the motor rotates or not? Is there a buzzing sound? If the motor can still generate power, then the motor is fine, it is possible that the pump pipe is blocked.

Rinse the relevant area. Dirty stuff, remove 1 time. If it still doesn't work, it proves that some part of the tube is missing.

Or the seal is not good. Let's check it carefully.

There are many reasons why the pump of a fish tank cannot get water. It may be that there is air in the inlet pipe or pump body, and it is necessary to check immediately whether it is full of water and look for wear or too looseness. It is also possible that the speed of the pump is too low, which is due to insufficient power, if it is not a mechanical failure, it is necessary to change to a higher power.

The pump is broken, or the plug is not plugged in properly; The water inlet or outlet of the water pump or the fan blade is blocked; The water level is too low, maybe the motor is positioned above the water surface, and the pump only sucks air. It generally occurs when the water pump is stopped and then restarted; Part of the bottom filtration submersible pump filter box can not absorb water after the water is empty, it will automatically stop, and it needs to be started by pressing the reset switch after restarting.

You see if it's casually that there's too much dust in it, it's blocked. Take it out and wash it all over. It's basically no problem with the installation. If not, it's probably broken.

Check if the power is on, and if it is on, it is not working. Then your pump may have broken down and needs to be replaced.

If the pump can't pump water, there may be a problem with the pump, or the pump is depressurized.

It should be that the pump is broken, and there is no electricity, or it is good to replace the pump.

The reasons why the pump of the fish tank cannot get water are: 1. There is air in the inlet pipe and the pump body, and it is necessary to check whether it is filled with water immediately, and at the same time see if there is any wear or too loose phenomenon that causes the pump to not pump water; 2. The speed of the pump is too low, due to the lack of power, it cannot meet the effect of self-priming, so that there is no pumping, if it is not a mechanical failure, it is necessary to change to a pump with higher power; 3. The suction stroke of the pump is relatively large, which exceeds its maximum suction stroke, resulting in its inability to absorb water after working and cannot be used normally.

1.Household self-priming pumps.

The reason why water cannot be pumped may be that the water inlet pipe of the household self-priming pump is not well sealed, such as the raw material belt at the connection is not properly wrapped, resulting in water leakage; Some users use household self-priming pumps to pump water from wells or pools, and there is no hose installed at the connection between the hose and the pagoda, resulting in water leakage; The household self-priming pump is always in the state of pumping air, so the household self-priming pump cannot just pump water.

2.The self-priming height of the domestic self-priming pump is basically between 6-8m, unless the deep well self-priming pump with high suction lift is 40m, if it is not within the specified self-priming height range, it has exceeded the effective self-priming height of the self-priming pump. This is also the reason why domestic self-priming pumps cannot hum.

3.The reason for the poor sound of the household self-priming pump may also be the mechanical seal of the household self-priming pump.

If it is broken, the air will be sucked into the pump body at the mechanical seal, and the self-priming pump will not be able to form negative pressure, resulting in the self-priming pump not being able to produce water.

4.The reason why the household self-priming pump cannot be filled with water is that the distance between the suction pipes of the self-priming pump is too long. Some users feel that the self-priming height of the household self-priming pump is not high when installing and using it.

This understanding is wrong. After the inlet pipe is long, there will be more air in the pipe, and after the self-priming pump self-priming time is long, the pump will heat up.

It will definitely cause the self-priming pump to not be filled with water. The total length of the suction pipe of the household self-priming pump with a self-priming height of 6-8m should be controlled in.

5.The reason why a household self-priming pump cannot make a sound may be that there are impurities in the pump body of the self-priming pump that clog the pump and impeller. It is also the reason why household self-priming pumps cannot make sound. After all the above reasons are discharged, it is recommended to disassemble the pump body to see if it is blocked.

There may be several reasons why the pump cannot pump water:

Low water level: As you said, if there are a lot of people around using groundwater, it can cause the water level to drop, you need to check if the current water level is below the pumping capacity of the pump.

Air leaks in the lines: If there is an air leak in the line, it can cause the pump to not create enough vacuum to pump water. Check whether there is air leakage in the joints, valves and other parts of the pipeline.

Pump inlet blockage: Check the pump inlet for debris blockage, and remove it if necessary.

Pump outlet blockage: Check the pump outlet for debris blockage, and remove it if necessary.

Non-self-priming pump: If you are using a non-self-priming pump, you need to fill enough starting water first, otherwise the pump will not be able to pump water.

Motor failure: Check whether the motor is working normally, if there is any abnormality, it needs to be repaired or replaced.

Check whether the sealing ring and mechanical seal of the water pump are worn or damaged, and replace them if necessary.

We recommend that you troubleshoot the possible causes one by one, identify the problem, and take appropriate measures to resolve the problem. If you are unable to identify the specific cause, it is advisable to seek the help of a professional for inspection and repair.

Probably. The pump is malfunctioning.

An inquest is required.

to troubleshoot and troubleshoot.

Probably. The level of groundwater is falling.

led to the suspension of the submersible pump.

The depth of the water level needs to be verified.

Adjust the submersible pump's dive position.

Because. A sharp drop in the water level of the oceans.

This has led to a drop in groundwater levels on land.

Caused a lot of pumps.

There is a phenomenon of not being able to pump water.

It is also necessary to further expand the submersible pump.

Deep dive pumping capacity.

1. The air in the pump is not drained before the pump is started, so it is necessary to fill the pump before starting.

2. Take a look at whether the inlet and outlet valves of the pump are opened, if they are not opened, they cannot absorb water, and then check whether there is a blockage in the pipeline, and clean up the blockage immediately.

3. Human operation error, the original motor is damaged, and a motor that is not the original is equipped, resulting in the flow head of the pump not meeting the parameter standard, then there will be no water.

4. There is also the disassembly and inspection of the pump body, cavitation will have an impact on the impeller, and there is the impact of friction on the impeller, the impeller is affected then the pressure can not come up, and the impeller should be replaced in time when this phenomenon occurs.

5. The pump will not be able to suck water when the pump is reversed, which is easy to solve and only needs to be adjusted.

6. The motor may be burned or lose magnetism, and the number of windings, wire diameter, and wiring method during the maintenance process of the motor may be changed by factors that may make the pump unable to pump water.

1. If there is no liquid storage in the pump or the liquid storage is insufficient, the solution is that you need to add enough liquid storage in the pump.

2. The solution is to eliminate the phenomenon of air leakage in the suction pipe of the water pump.

3. The voltage of the pump is too low, and the solution is to adjust the voltage.

4. If the suction stroke of the pump is too high or the suction pipeline is too long, the solution is to reduce the suction lift or shorten the pipeline.

5. The filter screen of the inlet pipeline in the pump is blocked by debris, and the solution is to clean up the debris on the filter screen of the inlet pipe of the water pump.

6. The impeller is damaged or worn, and the impeller blades will be worn or damaged after long-term use, which will affect the water pump. The solution is to replace the impeller with a new one.

The screws are not tightened during installation, resulting in water leakage and air leakage of the water pipe, unbalanced rotation of the impeller, and poor coupling of the connecting shaft, resulting in loose and broken parts, causing the water pump to produce large vibration and unable to pump water.

The situation you are talking about should be that the water level is too low.

This centrifugal pump can pump up to 10 meters of water underground, which is not pumped deeper than 10 meters.

The relationship between the two is very easy to learn like sailing against the current, sailing against the current. Imagine that when we see someone for the first time, we quietly use a human urn to drown the earth.

The reasons why the fish tank pump does not water may be:

There is air present in the inlet pipe and pump body. It may be that the self-priming pump is not filled with water before it starts, or it may be that the pump body and the inlet pipe foundation have a high slope, or the pump is worn out or the packing is too loose due to the high age of the pump, and if it is closed and lurking underwater for a long time, it will also cause corrosion, holes, cracks, etc.

The pump speed is too low. The speed of the water pump is low and can not achieve the effect of self-priming, there is no pumping, or the pumping power is insufficient, resulting in the pump pumping water, these factors are common in mechanical failure, improper installation, damage to the motor factors, improper configuration of the motor and other reasons.

The suction lift is too large. This may be closely related to the water source and the surrounding terrain, and the maximum suction lift of the pump is neglected, so the pump cannot absorb water at all after working. Therefore, when using a water pump, we must first understand the characteristics of the self-priming centrifugal pump and the maximum suction lift, depending on the occasion of use.

Try to switch again, if the pump can still rotate, generally switch a few more times, if not, check whether the water inlet is blocked, clean up the debris and then turn on the machine, and then see if the pipe fittings are loose, if the pipe fittings are not broken, the water can be on the water normally.

1.The water pump tank may be running out of water.

2.It could be that the pump is broken.

Hope it helps, thank you!
