What happens when the control box of the sewage pump shows a fault?

There can be a number of reasons why a sump pump control box is malfunctioning. Based on the situation you described, here are a few possible reasons:

Line fault: In the case of disconnecting the empty opening, unplugging the intermediate relay, and not connecting any load, the submersible pump integrated protector shows overheating, which may be a problem with the wiring inside the control box. Check the line for short circuits, poor contact, or other damage.

Protector failure: The submersible pump integrated protector itself may be faulty. For example, sensor failure, internal circuit failure, etc., resulting in false alarms overheating 1 and overheating 2 alarms.

Power supply problems: Unstable power supply or abnormal voltage may cause false alarms in the protector. Check the power supply to make sure the power supply is working properly.

To determine the specific cause, it is advisable to contact the manufacturer of the sewage pump control box to find out their views on the problem and the solution. At the same time, you can ask professional technicians to check the control box, find out the problem and fix it in time.

There are two situations: 1. If it is controlled by the inverter, it means that the inverter has detected a fault, and the detailed fault needs to be checked by the inverter**. 2. If it is a contactor.

Control, the fault light is on because the thermal relay protecting the motor tripped, after ruling out the overload problem of the motor, press the thermal relay.

The reset button resets. The pump has different uses, different liquid mediums, different flows, and the range of heads, therefore, its structural form is of course not the same, and the materials are also different, in summary, it can be roughly divided into: 1, urban water supply 2, sewage system 3, civil engineering, building system 4, agricultural water conservancy system 5, power station system 6, chemical system 7, petroleum industry system 8, mining metallurgical system 9, light industry.

System 10, ship system.

Summary. Hello dear! I have seen your question here, and I am trying to sort out the answer, and I will get back to you in five minutes, please wait a moment! ^

Hello dear! I have seen your question here, and I am trying to sort out the answers of several friends, and I will give you a reply in five minutes, please wait a moment! ^

Dear, you dress up well, there are generally two situations when the indicator light of the sewage pump control cabinet fails to light up1If it is inverter control, the hall is bright and indicates that the inverter has detected a fault, and the detailed fault needs to see the inverter's **. 2.

If it is a contactor to control the vertical elimination, the fault light is on because the thermal relay protecting the motor tripped, and after eliminating the motor overload, press the thermal relay restart button to reset.

Both show failures.

It is contactor-controlled.

The sewage pump has a reed tube float with a nuclear ball switch. There is also a cable type, the general fault light is basically the float switch is damaged, you can take it off and test it separately, confirm it, if it is damaged, you can dig and replace it!

Dear, hello as a cover, the information you have queried here is as follows: 1. The upper limit will not stop, that is, when the pressure reaches high pressure, it will not stop slag training; 2. The lower limit is not started, that is, the pressure is at the lowest, and the pump is still not started; 3. Overload protection, that is, the model of the motor and controller does not match; 4. There is a lack of phase protection, and the inlet line of the pump is loose. Common faults and solutions of water pumps: 1. Unable to start working, this is the first thing to check whether the power supply is normal, whether the power cord connection and switch are wrong, whether the fuse is burned, and if these situations occur, they must be repaired in time.

2. Mechanical faults in the pump, such as too much packing, and debris between the impeller and the pump body, resulting in blockage, can be dealt with by relaxing the packing and cleaning up the debris in the pump body, or directly replace the new pump shaft. 3. The pump body is heated, the bearing is damaged, the gap between the rolling bearing or the bracket is too small, etc., will cause the pump body to heat, the solution to this fault is very simple, first of all, if the bearing is seriously damaged, you can replace the new bearing, or add a gasket between the bracket and the bearing appropriately, so that the gap will become smaller

The fault light is on because the thermal relay that protects the electric machine jumps, and after eliminating the overload problem of the motor, press the reset button of the thermal relay to reset.

The working principle of axial flow pump is different from that of centrifugal pump, which mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. The lift on the water as the axial pump blades rotate pushes the water from below to above.

The blades of axial flow pumps are generally submerged in a pool of water from which the source is sucked. Due to the high-speed rotation of the impeller, under the action of the lifting force generated by the blades, the water is continuously pushed upward, so that the water flows out along the outlet pipe. As the impeller rotates, the water is continuously pressed to a higher place.

Hello dear! What is the reason why the sewage pump does not start, showing overload fault alarm light? Under normal circumstances, the pump overload indicator light is on and alarms, because the motor current is abnormal, exceeding the set range, and the thermal overload relay triggers the action and alarms.

The factors that lead to the abnormal current of the motor are nothing more than the unstable voltage, poor heat dissipation, and pipeline blockage, resulting in the increase of negative and wide loads. Therefore, the overload of the mold temperature machine pump should be investigated from the following aspects. Mold temperature machine pump inspection processing:

1) Check and measure the power supply voltage, whether there is undervoltage or phase loss (2) Check whether the motor vent of the pump is blocked, which affects the heat dissipation of the motor and causes excessive current (3) Check whether the pipeline valve of the mold temperature machine is smooth, whether the system has a high voltage state (4) Whether the thermal setting value of the thermal overload relay is low, check the mold temperature machine manual or consult the mold temperature machine to call the manufacturer, I hope to help you!

It just tells you that the pump is overloaded, go to check the pump, see if the pump is stopped, stop the instructions show no error, check whether the pump impeller is blocked by dirt, and there is that the general protective role is the action of the thermal relay, and the reset button of the thermal relay should be pressed before starting.

It would be nice to turn up the overload current a little bit.

What is the cause of the overload and undercurrent of the electric box controlled by the water pump, and how to deal with it?
