The sewage treatment pump does not run automatically is something that is broken

Maintenance and upkeep.

Basic approach. 1) Check whether there is any loosening of the sewage pump pipeline and joint. Turn the sump pump by hand to see if the pump is flexible.

2) Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, and the lubricating oil should be replaced or replenished in time. (3) Unscrew the diversion screw plug of the pump body of the sewage pump and pour the diversion water (or slurry). Self-priming sewage pump (4) Close the gate valve of the outlet pipeline, the outlet pressure gauge and the inlet vacuum gauge.

5) Jog the motor and try to see if the motor is steering correctly. (6) Start the motor, when the sewage pump is running normally, open the outlet pressure gauge and the inlet vacuum pump to see that it shows the appropriate pressure, gradually open the gate valve, and check the load of the motor at the same time. (7) Try to control the flow and head of the sewage pump within the range indicated on the sign, so as to ensure that the sewage pump operates at the highest efficiency point, so as to obtain the maximum energy-saving effect.

8) During the operation of the sewage pump, the bearing temperature shall not exceed the ambient temperature 35, and the maximum temperature shall not exceed 80. 9) If you find that the sewage pump has abnormal sound, you should stop it immediately to check the cause. (10) When the sewage pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.

11) In the first month of work, the lubricating oil shall be replaced after 100 hours, and the oil shall be changed once every 500 hours thereafter. (12) Adjust the packing gland frequently to ensure that the dripping situation in the packing chamber is normal (it is advisable to leak out into a drop). 13) Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large.

14) When the sewage pump is used in the cold winter season, after stopping, the lower part of the pump body should be unscrewed to discharge the medium. Prevents freeze cracking. (15) If the sewage pump is out of use for a long time, it is necessary to disassemble all the pumps, wipe off the water, and coat the rotating parts and joints with grease and install them.

What kind of pump does it look like? Are there any air leaks or power supply?

See what kind of pump you're using?

Dear, I am glad to answer for you: What should I do if the sewage pump cannot stop the pump automatically? A1

Generally, the sewage pump is automatically controlled, first of all, you have to check whether the sewage volume is too large and has not reached the stopping water level. 2.In addition, you just check the liquid level float to see if it is ** hanging?

Let him not fall, which will cause his signal to be on all the time, causing the pump to be unable to stop. 3.Then there is to check the level relay, there is a problem here, it may also cause its contacts to not be disconnected, so that the pump cannot be stopped.

4.Probably this kind of sewage pump keeps stopping the original of the tomb, just these points, I believe that there should be no problem to solve these points. If the sump pump can't stop, you can pull down the power switch.

1. Power failure: The sewage pump cannot be started automatically may be caused by the power supply blockage, and the power supply equipment connected to the power supply should be checked to see if it is faulty. 2. Circuit fault:

The failure of the sewage pump to start automatically may be caused by the fault of the circuit, and the control circuit of the sewage pump should be checked for fault, and the vacuum switch, contactor, automatic opening and other components of the circuit should be checked for fault. 3. Flow sensor failure: the sewage pump can not start automatically may be caused by the failure of the flow sensor, check whether the internal state of the flow sensor is normal, and check the input and output status of the control circuit of the electrical control device.

4. Failure of control device: the failure of the sewage pump to start automatically may be caused by the failure of the control device, and the control device should be checked whether it is faulty, and the input signal, control signal and voltage status of the control device should be checked, as well as whether the circuit board in the control device is faulty.

There can be a number of reasons why a sump pump doesn't start automatically, but here are a few common reasons and how to deal with them:

Float failure: Sump pumps are usually equipped with float switches to control automatic start and stop, and if the float fails, the pump will not start automatically. At this time, it is necessary to check whether the float is stuck, whether it is damaged, and if there is a problem, it needs to be replaced.

Power supply problem: The sewage pump needs power supply to work properly, and if the power supply fails, such as short circuit, open circuit, etc., the pump will not start. At this time, you need to check whether the power supply line is normal, whether the power supply is energized, whether the wire connector is loose, etc.

Mechanical problems of the pump: Mechanical failure of the sewage pump may also cause the pump to not start automatically, such as bearing failure, motor failure, impeller blockage, etc. At this time, it is necessary to check whether the mechanical parts of the pump are normal, and if there is a problem, it needs to be repaired or replaced.

Controller failure: If the wastewater pump uses an automatic controller to control the Qilu Sudden Stop, the controller failure may also cause the pump to not start automatically. At this time, you need to check whether the controller is normal, and if there is a problem, it needs to be repaired or replaced.

It is necessary to carry out specific investigation according to the actual situation, if it cannot be solved by yourself, it is recommended to ask professional and technical personnel for maintenance.

There can be many reasons why a sump pump won't start automatically, here are some possible reasons and how to fix it::

Water level sensor failure: The automatic start and stop of the sewage pump is usually achieved by the water level sensor, if the water level sensor is faulty, the sewage pump cannot be started automatically. The solution is to check if the connection of the water level sensor is loose or damaged, and if there is a problem that needs to be replaced or repaired.

Controller failure: The controller for the automatic start and stop of the sump pump may also malfunction, resulting in the failure to start automatically. The solution is to check whether the power supply of the controller is normal, whether there is a fault indicator light on, and if necessary, troubleshoot or replace the controller according to the instructions of the controller.

Power failure: The automatic start and stop of the sewage pump needs the support of the car power supply, if the power supply fails, the sewage pump cannot be automatically started. The solution is to check if the power supply is normal, whether there is a voltage output, and if the power supply fails and needs to be repaired or replaced.

Pump body blockage: If the pump body of the sewage pump is blocked by dirt, it will cause the pump to not function properly and cannot start automatically. The solution is to clean the pump body or replace the sump pump.

Motor failure: The motor of the sewage pump is faulty, which will also cause the pump to fail to run normally and not start automatically. The solution is to check if the connection of the motor is loose or damaged, and if the motor needs to be replaced.

What should I do if the sewage pump can't stop the pump automatically? Hello dear, 1Generally, the sewage pump is automatically controlled, first of all, you have to check whether the amount of sewage is too large, and the water level has not yet reached 2

In addition, you just check the liquid level float to see if it is ** hanging? If he doesn't fall down, this will cause his signal to be on all the time, causing the pump to not stop.3Then check the liquid level relay, there is a problem here, it may also cause its contacts to not be able to disconnect, resulting in the pump can not stop 4

1. The motor fails to start.

The voltage of the sewage pump motor is too low to cause the normal start-up, so the entire power supply system should be checked, and there is no sound when the closing motor is not running, so it can be judged that the skin beam is not connected to the circuit, considering the open circuit, it is necessary to check whether the insurance is intact, and then check whether the stator winding of the motor is burned; If the motor does not run but there is a sound after closing, check the power cord and stator windings after the shutdown.

It is worth mentioning that the motor will be overloaded due to excessive current resulting in power-off protection, it is necessary to adjust the voltage to the normal value, and properly adjust the tightness of the shaft gland and shaft seal of the Herot pump, and then replace the pump shaft.

2. The impeller or bearing is blocked and stuck by foreign objects.

The sewage pump has excellent overflow properties, but if the medium exceeds the transportation standard of the equipment, it will cause the impeller in the pump to be blocked and stuck by foreign bodies.

First, the failure of the motor gas operation leads to the inability to start the sewage pump motor voltage is too low, which will lead to the failure to start normally, so the entire power supply system should be checked, and there is no sound when the motor is not running when closing, which can be judged to be the circuit is not passable, considering the open circuit, it is necessary to check whether the insurance is intact, and then check whether the stator winding of the motor is burned; If the motor does not run but there is a sound after closing, check the power cord and stator windings after the shutdown. It is worth mentioning that the motor will cause power-off protection due to excessive current when overloaded, and it is necessary to adjust the voltage to the normal value, and properly adjust the tightness of the pump shaft gland and shaft seal, and then replace the pump shaft. Second, the impeller or bearing is blocked by foreign bodies and stuck in the dead skin beam sewage pump has excellent overflow, but if the medium exceeds the transportation standard of the equipment, it will cause the impeller in the pump to be blocked and stuck by foreign bodies, in this regard, it is necessary to clean the foreign matter in the pump in time, and check the wear of the components, and consider maintenance or replacement of new parts according to the needs.
