What is the reason why the well cannot pump water for a period of time?

Reasons and solutions for the failure of household well pumps to pump water.

Reason 1: The water pump vibrates violently.

It may be that the impeller rotor is unbalanced, or the coupling is poorly combined, and the bearing is worn and bent; It may also be loose or cracked in some parts; Maybe it's because the tubing bracket is not strong, etc. It can be dealt with by means of adjustment, repair, reinforcement and replacement.

Cause 2: Leaking water or air in the pipeline.

It is possible that the nut is not tightened during installation. If the leakage is not serious, cement or cement slurry mixed with asphalt oil can be applied to the area of air or water leakage. Temporary repairs can be made with wet mud or soft soap.

If there is a leak at the joint, the nut can be tightened by hand. If the water leakage is serious, it must be reassembled.

Reason 3: The filler is overheated.

Mostly because the packing is pressed too tightly, the cooling water cannot enter the packing, or the shaft surface is damaged. Measures such as appropriately relaxing the packing and cleaning up the sealing tube can be taken. Wear-out packing must be replaced with a new one.

Before installation, soak in the oil and fill it in one circle at a time, and the cuts should be staggered, so as to reduce water leakage. After the last round of packing is loaded, the gland should be tightened, and the tightness should be adjusted during operation.

Reason 4: The air is not filled with water or the air from the inlet pipe is not pumped clean.

Solution: Continue to fill the water or drain the air from the inlet pipe.

Reason 5: During on-site installation, the inlet and outlet directions are reversed or the motor wiring is incorrect, and the rotation direction of the pump is incorrect.

Solution: Swap the inlet and outlet directions, and the motor wiring is incorrect, and replace any two of the wires to change the direction of rotation.

If you are sure that the pump is good and the connections of the pipe are not leaking, then it is whether your well is relatively deep, and this situation is estimated to be the reason why the water level of your well is too low, and the height from the motor has exceeded or approached 10 meters, and the principle of pumping water is to use atmospheric pressure (that is, the pressure of the air around us on objects), and one atmosphere is equivalent to the height of 10 meters of water, and if the height of the water in your pipe is more than 10 meters, of course, there is no pressure to suck the water up. You can try lowering the height of the pump or increasing the height of the water surface, or you can just change it to a pump, because the pump is working in well water, and that doesn't happen.

The water pump is easy to do, is your well sealed with soil? If it is sealed, dig it up, or the problem can only be guessed, it is better to do it if it is not sealed, and then tie it with a long rope to quickly fall into the well to measure the height of the well water, remember not to put it too fast, until it is obvious that the weight of the rope becomes lighter, and then pull up the rope, look at the length of the rope to become wet, you can see the height of the well water; Since the well water is dependent on the surrounding water as a supplement, generally if the water depth is less than 1 meter, it is likely to be the reason for the lack of water, which can only rely on the transformation of the well; If the water depth is more than two meters, can you pump up the water without sealing the well? If you can't, most of the reason is the water pump, maybe the performance is poor, unstable, or the voltage is low or the voltage is insufficient due to the leakage of the pump wire, try to change the wire, and only change the water pump to try!

Well water is groundwater, so it can't be used up. In the hot summer, the earth's surface is directly affected by the sun's irradiation and air currents, and the temperature rises quickly. The soil in the ground can only absorb heat from the atmosphere through the upper layer of soil, and because the soil transfers heat very slowly, the temperature deep underground is lower than the temperature of the ground, so the temperature of the well water is also lower than the temperature of the ground.

In the cold winter, the temperature of the ground decreases quickly, and the soil deep underground cannot dissipate heat directly into the air, so the temperature does not change much, and the temperature of the well water is higher than the temperature of the ground.

Well water, for thousands of years, has nourished and nurtured countless Chinese sons and daughters, creating a glorious chapter of the Chinese nation. The water in the well, drinking more can dissipate heat and detoxify, which is conducive to red and hot urine, too astringent, and drunk to death, in addition, if there is no discomfort, drinking more will also be good for the body. Drinking it all year round is beneficial to physical and mental health, and making tea is especially sweet and sweet.

The water in the well is pumping less and less, what is the reason?

The water in the well is pumping less and less, what is the reason for your dear, the pump may be blocked, so now the water is getting smaller. At the beginning, due to the high liquid level, the water was enough, and the liquid level slowly decreased by the mu infiltration, and the water was not enough. The head of the pump is too low, the liquid level is high at the beginning, and the pumping is normal.

The failure of the deep well pump to pump water may be due to the water level being lower than the suction inlet of the pump, or it may be due to the leakage of the water pipe or the unsealed connection, or the loosening of some impellers, the reversal of the motor, the blockage of the pipeline, etc. You can first check whether the pipeline is blocked, whether the water level is up to standard, check whether the motor, impeller, etc. are faulty, and then repair them according to the relevant reasons. If you can't find the fault and fix it, you can contact the manufacturer's after-sales service, ask the reason, and then repair it.

The maintenance and maintenance of deep well pumps in the process of use include the following aspects:

1.During the operation of the electric pump, the flow rate of current, voltmeter and water should be constantly observed, and the electric pump should be operated under rated working conditions.

2.The valve should be used to regulate the flow rate and the head shall not be overloaded.

3.It is necessary to constantly observe the instrument, check the electrical equipment, measure the insulation resistance once every half a month, and the resistance value is not less than a megaohm.

4.Each drainage and irrigation period (2500 hours) is overhauled and protected, and the wearing parts are replaced.

If the well pump is not faulty, but suddenly it can't pump water, then there are several possible reasons:

1.Lower water level in the well: If the water level in the well drops, the pump will not be able to pump water. This can be due to drought, long periods of no rain, reduced snowfall, etc.

2.Water leakage: If there is a leak in the pipes of the well, the pump will pump the water to the leakage point instead of pumping to the outlet, causing the water level in the well to drop and the water cannot be pumped.

3.Debris or sand in: If debris or sand is in the well and clogs the pump or pipe, it will cause the pump to not pump properly.

4.Power failure: The pump needs to stabilize the pure unstable power** in order to run normally, and if the power supply failure or power line is damaged, the pump will also fail to work.

5.Frequency variation: If you are using a frequency converter-controlled pump, it can cause problems due to frequency changes. Sometimes, due to the voltage change of the power supply network, the frequency of the inverter will change, which will cause the pump to not start properly.

In short, if the well water pump suddenly fails to pump water, you can check the water level in the well, whether the pipeline is leaking water, whether there is debris or sand, whether the electricity is normal, or contact professionals for maintenance and inspection.

Summary. Hello, glad to answer for you. OK.

It may be that the one-time water consumption is too large, and the soaking water volume cannot keep up, and it will be good to wait for a day, or the water glands are sealed by silt, and the water is slow, so clean it up with a bamboo pole. There is also the possibility that the water glands are thirsty, and the water output itself is not good, so the well can only be dug again. Or it means that the well water in your house is shallow, and you can continue to dig a little deeper.

The well water was accidentally drained. Can it still come out of the water.

Neighbors pumped water for two days. I accidentally drained my well. The machine has a sound. It's just not out of the water.

You wait for the night and see tomorrow, usually as long as the well is deep enough, the water will come out tomorrow.

Good. Thank you, dear

You're welcome. Have a great day.

Why is the water pumped out of the well muddy, this has not been the case before.

1. The water pumping of the well will be muddy, mainly because the water level of the well is declining after being used for a long time, and the water level at the bottom of the well is lower than the position of groundwater, which causes the silt and sediment at the bottom of the well to be pumped out and form muddy water; 2. In addition, the water pumped from the well will be muddy, which may also be caused by surface pollution, because when the well is pumped, the water flow will take away the pollutants on the surface and bring them into the well, which will also make the water pumped out of the well become turbid. 3. Finally, the water pumped from the well may also be caused by changes in the environment around the well, such as changes in the surface soil, which leads to an increase in silt and sediment in the well, and will also make the water pumped out of the well turbid.

If the manual pressurized water well cannot produce water, it can be filled with water and then pressed.

The pump body is not filled with water, the residual air compressibility is much greater than that of water, and the water lifting effect is small, and the piston and one-way valve are not well sealed, and the air leakage makes the lifting force lost.

Reasons why the self-priming pump can't pump up the water:

1. The suction stroke is too large, that is to say, the distance from the suction port to the impeller has exceeded the centrifugal force of the impeller;

2. If the inlet pipeline is leaking, check whether the pipeline and flange interface are in good condition;

3. The inlet valve is not opened, and the pipeline is not smooth;

4. The impeller cannot work, whether it is broken or stuck;

5. The mechanical seal ridge is seriously leaking, and the amount of saliva is small, and it is mistaken that it cannot absorb water.
