WQ submersible sewage pump performance characteristics and precautions

2020-12-22
The WQ submersible sewage pump uses a unique structure and a new mechanical seal to efficiently transport solids and long fibers. Compared with the conventional impeller, the impeller is in the form of a single flow channel or a double flow channel. It is similar to a curved pipe of the same cross-section. It has very good over-flow and is equipped with a reasonable volume to make the pump efficiency, and impeller dynamic and static balance test, so that the pump has no vibration during operation.

WQ submersible sewage pump is suitable for chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel mills, power plants, coal processing industries, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites, and other industries. Sewage and dirt can also be used to pump clean water and corrosive media.

WQ submersible sewage pump performance characteristics:
1、Can be used in the full head, and ensure that the motor will not overload.
2、There are two different installation methods, fixed automatic coupling installation system and mobile free installation system.
3、The mechanical seal adopts a new hard and corrosion-resistant softening tungsten material, which can make the pump run safely for more than 8000 hours.
4、The float switch can automatically control the start and stop of the pump according to the required liquid level change, without special care, it is very convenient to use.
5、The overall structure is compact, the volume is small, the noise is low, the energy saving effect is remarkable, the maintenance is convenient, the pump room is not needed, and the water can be used to work, which greatly reduces the construction cost.
6、The pump sealing oil chamber is provided with a high-precision anti-interference water leakage detecting sensor, and the thermal resistance component is embedded in the stator winding to automatically protect the pump motor.

WQ submersible sewage pump precautions:
1、The power must be turned off when checking the electric pump.
2、After the machine is stopped, it cannot be restarted until the motor is completely stopped.
3、When the submersible pump is working, do not wash the items nearby, swim or put the animals into the water, so as to avoid electric shock when the electric pump leaks.
4、When the humidity sensor or temperature sensor issues an alarm, or when the pump body is running, the vibration and noise are abnormal; or when the output water pressure drops and the power consumption rises significantly, the submersible sewage pump should be shut down immediately for maintenance.
5、When some submersible pumps with poor sealing are immersed in water for a long time, even if they are not used, the insulation value will gradually decrease, and finally it will not be used, even in the short time that the continuous operation of the submersible sewage pump in the water. The insulation disappears.
6、The submersible pump should not be opened or stopped too frequently, otherwise, it will affect the service life of the submersible pump. When the submersible pump stops, the water in the pipeline will return to the water. At this time, the restart will cause the load of the electric pump to be overloaded and bear unnecessary impact load. In addition, the submersible pump will open and stop too often to damage the impact. Poorly capable parts and damage to the entire electric pump.
