Causes of overload of self-priming non-clogging sewage pump
(Summary description)What are the reasons for the overload of the self-priming non-blocking sewage pump? The following editor will give you an introduction.
1. A motor with low power supply voltage and high power cannot start when the voltage is too low. Even after starting and running, the current will be large, which will overload the motor. The reason for the low voltage is that, in addition to the low voltage of the power grid, sometimes the cable transmission distance is too long and the cable cross-sectional area is too small, which will cause the voltage to drop, and sometimes the transformer capacity is too small, which can also cause the voltage to be low. The solution is to find out the cause, and find an electrician to solve it collaboratively.
2. The gate valve is not closed when starting. According to normal operation, the gate valve should be closed first, and then the water pump should be started. After the pump runs normally, the gate valve should be slowly opened. It is much larger, so the gate valve should be closed first or close to closing when starting to reduce the starting load of the motor.
3. The packing gland is pressed too tightly. When filling the packing, the packing gland is pressed too tightly, which will increase the friction between the packing and the pump shaft sleeve and increase the motor load, which is especially obvious in small pumps. Therefore, when filling the packing, the self-priming non-clogging sewage pump should properly adjust the pressing force of the packing gland to reduce the packing tightness.
4. The water discharge pipe of the balance room is blocked. The balance room usually has a water discharge pipe, some of which are directly open to the atmosphere, and some are connected to the suction side to communicate with the suction section. This is indispensable to reduce the back pressure of the balance plate. It cannot be blocked or blocked due to other reasons. Otherwise, the water pump cannot be started because the balance device does not work and the axial thrust cannot be balanced. The balance plate and the balance plate are directly rubbed. The motor is so loaded that it cannot be started.
The above is the reason why the self-priming non-clogging sewage pump is overloaded. I hope you can understand it.
