    Automatic suction pump not turning can be caused by a number of reasons. Here are some possible reasons:

    Power supply problem: Check whether the power cord and plug are well connected and whether the voltage is normal. Power interruptions or voltage instability may cause the pump to fail to start.

    Motor failure: Check whether the motor windings are short-circuited, open-circuited, or burned. Motor failure may require professional repair or replacement.

    Starter failure: The starter of the automatic suction pump may malfunction, resulting in a failure to start. Check the connection and working condition of the launcher.

    Overload Protection: If the pump is overloaded for a long time, the overload protection device may trigger, stopping the pump. Check that the working load of the pump is not too heavy and make sure that the pump is operating under normal operating conditions.

    Stuck pump: The impeller or shaft inside the pump may be stuck due to jamming or wear from debris. The pump needs to be dismantled to check the condition of the impeller and shaft, remove debris or replace worn parts.

    Damaged bearings: Worn or damaged bearings may cause the pump to not rotate properly. Bearings need to be replaced.

    To solve these problems, it is necessary to first determine the possible causes according to the specific fault phenomenon, and then carry out targeted inspection and maintenance. Regular maintenance of the pump to ensure that it is operating under the correct operating conditions can effectively reduce the possibility of failure. If the problem cannot be resolved, it is recommended to contact a service professional or pump manufacturer for support.

    Since it is automatic (start-stop), it must have an automatic control circuit or an element (such as a pressure switch or a contact pressure gauge).

    So the reasons why it doesn't turn could be the following:

    First, the reason for the pump.

    1. The impeller is stuck.

    2. The motor coil of the water pump is damaged.

    3. There is a problem with the pump circuit. (disconnection and other reasons).

    Second, there is a problem with the start-stop control circuit and components of the water pump.

    The above reasons can cause the pump to not rotate, and it is necessary to pay attention to inspection to determine the cause of failure.

    Common reasons why the pump won't turn:

    1. If the motor is humming, it is a lack of phase in the motor.

    2. It is also possible to click lock, which means that the bearing is damaged and can no longer be used.

    3. There is a possibility that the water pump is blocked.

    4. The control line is faulty and cannot be started.

    The reason why the automatic suction pump does not rotate may be due to motor failure or the obligation in the pump body to cause jamming.

    1. Not turning may be damage to the starting capacitor or starting winding.

    2. If the starting capacitor or starting winding of the motor of the household self-priming pump is damaged, the capacitor of the same capacity should be replaced or the starting winding should be repaired.

    3. The working principle is: fill the pump casing with water (or the pump casing itself contains water) before the pump is started. After starting, the high-speed rotation of the impeller makes the water in the impeller channel flow to the vortex shell, and then the inlet forms a vacuum, so that the water inlet backstop door is opened, and the air in the suction pipe enters the pump, and reaches the outer edge through the impeller channel.

    Answer: Do you cause the centrifugal pump not to work, does not rotate, or for other reasons, does not install can check the motor failure. 1. Whether there is electricity or not, 2. Whether the motor is burned out.

    If there are other reasons, please implement the following exclusion methods. , 8 Troubleshooting: Unable to Raise Water:

    a) The pump is not filled with water. b) The rotational speed is lower than the rating. c) The head of the system used is too high.

    d) The entrance height is higher than the original design.

    Question: The centrifugal pump has been working for six hours, the water tank is empty, the centrifugal pump can't be started when the water is full, and when it starts, it feels like something is stuck inside, and it will automatically shut down.

    Answer: If the centrifugal pump is not filled with water, there will be a section of air in it, which is difficult to pump water, and the so-called siphon principle is actually similar to this. Moreover, the centrifugal pump can obtain a centrifugal force by throwing water, that is, it can generate negative pressure by this force.

    Hello, about your question I think if it is a single-phase can check the flexibility of the capacitor and the motor, turn it by hand, see if it is tight, it is estimated that it is mostly caused by the capacitance, it may also be a screw problem, try it by hand, if it is alleviated by butter, and the serious one must replace the full set of screws.

    There may be two reasons why the single-phase self-priming pump does not rotate: one is that the shaft of the motor cannot rotate due to mechanical jamming or rusting, and the other is that the outer surface of the rotor and the inner surface of the stator are in contact due to the damage of the bearings at both ends of the motor, and the rotation cannot be generated, so the motor does not rotate.

    Hope it helps.

    Summary. Hello, the suction pump is a self-priming centrifugal pump, which has the advantages of compact structure, easy operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. It is a type of water pump that does not require a foot valve to be installed in the pipeline.

    When there is debris blockage in the pump body or pipeline, there will also be a situation that the self-priming pump cannot be watered, and the debris needs to be cleaned up so that the pipeline and the pump body are unblocked.

    The self-priming pump needs to contain a certain amount of fluid extraction when it works, so it is necessary to load the water into the self-priming pump before use.

    Insufficient water pressure, too long water pipes, and poor sealing of the pump will also cause the inlet part of the pump to fail to form a vacuum and cause water to not be filled.

    Leaking air from the water pipe, leaking water, or poor sealing of the water supply pipe will also cause the self-priming pump to fail to supply water, and the water pipe can be repaired or replaced.

    Check whether there is air leakage at the leakage of the machine, if there is air leakage, you can repair it by adding gaskets and tightening screws.

    The self-priming pump is working normally but does not run on water.

    Reasons why the pump can't pump water.

  15. Anonymous users2024-01-30

    1. There is air in the inlet pipe of the water pump and the pump body of the water pump. 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.

    2. The speed of the pump is too low. Some users are driven by another motor due to the damage of the original motor, resulting in small flow, low head and even no water.

    3. The suction stroke of the water pump is too large. Some water sources are deeper, and some water sources are flatter on the periphery, and the allowable suction range of the pump is ignored, resulting in little or no water absorption. It is important to know that there is a limit to the vacuum that can be established at the suction port of the water pump, and the suction stroke of the absolute vacuum is about 10 meters high in the water column, while the water pump cannot establish an absolute vacuum.

    Moreover, the vacuum is too large, which is easy to vaporize the water in the pump, which is not conducive to the work of the pump.

    Are you talking about not being able to absorb water, or the head is not enough and the water pressure is low. If you can't absorb water, it may be that the pump is not filled with water, or the water inlet end is leaking, and the impeller is seriously worn. The water pressure is low, it may be the outlet end, the water pipe is blocked, and then the impeller is seriously worn.
