What is the reason why the pump sometimes goes on and sometimes doesn t?

Half of them are sometimes on the water, sometimes they are not, what is the reason? What do I think is the reason for this? If the pump is not broken, it is a good water pump, sometimes it is on the water, sometimes it is not on the water, it means that you have half of the power to pad, sometimes it is on the water, sometimes it is not on the water, what is the reason?

What do I think is the reason for this? If the pump is not broken, it is a good pump, sometimes it is on the water, sometimes it is not on the water, it means that you have a pad, there is power, you have no electricity on the water, he will not go to the water, this is a reason, and another may be if the pump is broken, maybe the first round of the pump is cowardly, sometimes he is on the water, sometimes it is broken, and he is not on that place, because his impeller is sometimes half of the water is on the water, sometimes not on the water, what is the reason? What do I think is the reason for this?

This may be due to the presence of air in the inlet pipe and pump body, the speed of the pump is too low, the suction stroke of the pump is too large, and the water leakage at the pipe interface. If there is air in the inlet pipe and pump body, just drain the air directly. If the speed of the pump is too low, see if it is caused by motor damage, and if so, replace it with a new one.

And if there is a leak at the pipe interface, just put the nut.

Tighten it.

This situation should be that the water pump is too shallow, after the pump starts to work, the water level in the well will drop, the water inlet of the pump is exposed outside the water, and the pump will not be able to suck water, so that the pump will not be able to suck water on the top, and when the water outside the well seeps into the well and does not pass the pump inlet again, the pump can suck water again, and when the pump is on the water, when the pump sucks again, the water level will drop again, and the pump will not be able to suck water.

To solve this problem, you can put the pump down a little deeper, and the water inlet will not be exposed.

The pump is sometimes on the water, sometimes not on the water, in fact, the main pump is sometimes on the water, sometimes not on the water, in fact, the main reason is very likely, is the pump motor bearing is broken, is the pump motor bearing broken.

The pump is sometimes watered, sometimes not watered, if the motor pump is running normally, most of the cases are caused by water leakage caused by foreign objects in the check valve or closed door.

If there is no reservoir in the pump or there is not enough reservoir, the solution is that you need to fill up the reservoir in the pump.

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

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

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

The impeller is stuck with foreign bodies, and when the current is too large, the original water pump has a built-in thermal overload power-off function, and there may be poor lubrication of the motor bearing, resulting in a large pump current.

If the pump and power supply are not faulty, it may be that the liquid level is too low (this is often the case with sewage pumps), and the liquid at the pump inlet is pumped too low and will not be watered, and after a while, the surrounding liquid will gradually gather to a certain depth at the pump inlet and then it can be watered again.

The water pump can sometimes be watered, sometimes can not be watered, indicating that its power is insufficient, or there is a problem with the internal parts, it is best to recommend maintenance or direct replacement of the water pump with better quality, so that the water will be more stable.

The water pump is an electrical appliance that requires high voltage, so the water pump will cause your current voltage to be unstable when it is used, and it is not easy to get on the water when the voltage is relatively low, and you can use the water when the voltage is normal.

Sometimes if the water does not come, it should be that his impeller is faulty, which depends on what kind of pumping method your pump takes, and it needs to be opened for detection.

When the pump is pumping water, it may also be blocked due to foreign matter in the water, I only know that there is such a situation, because I have encountered other ones that are not very clear, I hope to help you.

It is possible that the low amount of water from the pump is related to the depth of the water level. There is also poor contact. You can also buy a fully automatic water pump with air capsule, with air bag type water pump.

The water pump sometimes goes on and sometimes does not water is related to the automatic control of the water level controller or induction switch, which should be checked.

Dear, I am glad to answer for you: the reasons and solutions for the pump not to water are as follows: 1. Check whether the valve at the inlet of the pump is opened, please open it if it is not opened.

Whether there is water at the inlet or not, and whether there is a foreign body or not is blocked. If there is no water, the water tank is missing, and replenishing water can solve it. 2. When starting for the first time, the pump needs to be emptied.

3. Check whether it is reversed, which stool pump can not hit the water when it is reversed, adjust the forward rotation of the water pump (clockwise to positive rotation), if there is inverter control, it is necessary to manually and automatically jog to view. 4. Check that the outlet pipeline is not blocked. 5. If all of the above is normal, then look at what the head on the nameplate of the pump is.

If there is water coming out, but the pressure cannot be reached, please close the outlet main valve first, start the water pump, see if the pressure can reach or exceed the set pressure, and try one by one. If the set pressure can be reached or exceeded, then start N-1 pump (N is the number of main water pumps), slowly open the main valve, and stop rotating when the pressure is equal to the pressure on the nameplate. If the flow rate is not enough for the user at this time, then the flow rate of the pump is small, and the pump needs to be increased or replaced with a large flow pump.

6. If the pressure of the main valve is still not up, the pump should be disassembled to see if the impeller falls off or is damaged in the pump body, if so, please worse.

The reasons why the pump cannot pump water are as follows:

1. When the pump is started for the first time, the air in the pump needs to be discharged;

2. Check whether the inlet and outlet valves of the pump are opened, whether the inlet of the pump is sucked with water, whether there is any foreign body blockage in the inlet and outlet pipes of the pump, whether there is a shortage of water at the inlet of the water source of the pump, and if there is a shortage of water, replenishment can solve the problem;

3. For human reasons, some users have damaged the original motor of the pump, and they feel that it is okay to match a motor at will, resulting in a small flow rate of the pump, low head, and even the result that the pump does not use water;

4. After closing the pump valve, the pump pressure can not go up, disassemble the pump body, check whether the impeller in the pump body has the problem of falling off or damaged, if there is such a phenomenon, it is recommended to replace or repair it as soon as possible;

5. Check whether the pump has a reversal problem, sometimes the pump can not be on the water, adjust the pump steering problem can be solved, if the water is controlled by the inverter, it needs to be checked manually or automatically respectively;

6. Due to the burning or loss of magnetism of the motor winding of the water pump, the change of the number of winding turns, wire diameter and wiring method during the maintenance of the motor, or the change of the speed of the electric water pump due to the failure of the motor during maintenance, resulting in the sound of the water pump not being able to get water;

7. The resistance of water flow in and out of the pipeline is too large, and the pump pipeline is too long or there are many curves, resulting in too much resistance of the water flow pipe, although the vertical distance from the outlet to the water source is less than the rated head of the pump, but there will still be the problem that the pump can not lift water or water.

There are four reasons why the pump doesn't go down to water, such as accompanying the state

1. The valve at the inlet of the pump is not opened, or the valve port is blocked by foreign objects, resulting in the pump not being able to use water;

2. The pump does not go to water due to reverse, or the water outlet is blocked, and the reed chain causes the pump not to go to water;

3. The impeller in the pump body falls or is damaged, resulting in the pump not being able to water;

4. The pump does not reach the required flow rate and head, resulting in the pump not being able to call for water.

The four reasons why the pump does not use water are as follows: 1. The valve at the inlet of the pump is not opened, or the valve port is blocked by foreign objects, resulting in the pump not being able to use water; 2. The water is reversed as a car pump and the water is not watered, or the water outlet is blocked, resulting in the water pump not being watered; 3. The impeller in the pump body falls or is damaged, and the pump does not go to water; 4. The pump does not reach the required flow rate and head, resulting in the pump not being able to use water.

Summary. Hello, this situation may be that there is air in the inlet pipe of the pump and in the pump body.

The pump is not filled with enough water before starting, and sometimes it looks like the filled water has overflowed through the vent, but the air is completely discharged without turning the pump shaft, leaving a little air in the inlet pipe or pump body.

What is the reason why the pump in normal operation suddenly does not water?

Hello, this situation may be that there is air in the inlet pipe and pump body of the pump is not filled with enough water before the pump starts, sometimes it seems that the filled water has overflowed from the vent, but the air is completely discharged without rotating the pump shaft, resulting in a little air remaining in the inlet pipe or pump body.

Our water pump is the main water pump, and the water is not filled and diverted, and the air is discharged through the jet valve, and then the water is discharged, and it is checked to see if it is blocked.

It started normal, but suddenly it didn't go on when it was up.

What is the main part to be examined.

Check that there is no blockage at the water inlet or water inlet pipe.

Then check whether the impeller in the pump body has fallen or is damaged.

And what else is the reason.

Pro, there is a high possibility that the valve port is blocked by foreign objects, and it is also possible that air enters when pumping.

You mainly look to see if there is a blockage.
