Submersible sewage pumps generally use mechanical seals, so the cause of leakage is basically caused by problems with mechanical seals. When used in strict accordance with the operating standards, the operation should be often inspected, early detection of problems. It is necessary to regularly replace the consumable parts of the pump, such as rolling bearings and mechanical seals, so as to broaden the service life of the pump and ensure normal manufacturing.

1, the leakage caused by too much pressure High pressure pump in the case of overpressure and vacuum pump operation will lead to mechanical seal leakage. During the startup and shutdown process of the centrifugal pump, due to the obstruction of the inlet pipe and the vapor body contained in the conveying fluid medium, negative pressure may occur in the sealing chamber, resulting in dry friction of the sealing port, resulting in steam leakage or water seepage caused by the built-in mechanical seal. The difference between the vacuum pump seal and the positive pressure seal depends on the specificity of the seal object, and the mechanical seal also has the ability to adapt to the direction, which requires opening the gate valve of the relevant pipeline before running the weapon equipment, checking the level meter, and avoiding the leakage caused by operational errors.

2, no clogged sewage sewage pump periodic leakage motor rotor periodic vibration can lead to periodic leakage, this is because the motor stator and how many bearing end caps are not aligned or centrifugal impeller and spindle bearing imbalance, such things will reduce the service life of the seal ring, need to be checked and repaired in time.

3, mechanical seal damage This is also a more common reason for the leakage of submersible sewage pump, so in the normal use of the pump, it is necessary to often check the application of the pump, whether there is a change, but also regularly replace the mechanical seal of the pump, in order to avoid leakage because of the damage of the mechanical seal!

To sum up, there are many reasons for the leakage of non-clogged sewage sewage submersible sewage pump. After years of practical activities, professional and technical personnel of Haobangmei Electromechanical Co., Ltd. have summarized the above 6 types of reasons. Therefore, we should check one by one on time to prevent a variety of reasons leading to leakage. Once there is leakage, the customer unit should first find out the root cause of the leakage, and replace the old damaged parts regularly to ensure that there will be no secondary leakage.
