Model significance

WQ(WQB) series submersible sewage pump

Structure characteristics

WQ(WQB) series submersible sewage pump

1 impeller and spiral case
Careful selection and matching of the impeller and the spiral case, so that the flow passage through the performance is good, high efficiency, with a full head without overload characteristics. Precise balance of impeller, small vibration, stable rotation.
2 Motor
Specially designed submersible motor, the protection level is IPX8, the stator winding insulation class is F level (155 degrees C), under normal temperature rise condition, the motor insulation life is prolonged.
The 3 seal
The motor shaft seal using two to three series mechanical seal, seal form reliable multi line. In the medium, the sealing surface increases with the increasing of the pressure of the medium, and effectively prevents water from entering the oil chamber. Another two in the oil chamber, to prevent oil into the motor, if the first failure, the other two can still prevent oil into the motor. Under normal usage, the trouble free running time is over 9000h.
4 oil room
In the oil chamber filled with suitable mechanical oil, the second mechanical seal is installed, the oil chamber is to prevent the media from the pump shaft into the motor of a barrier to prevent the media penetration into the motor, if the first mechanical seal leakage, by the oil chamber buffer medium can not directly into the motor, also on two independent mechanical seal friction surface lubrication and cooling, so that the machine seal is reliable.
5 bearing
Lower bearing motor pump shaft support reliable, sewage pump work according to the radial, axial force and fluctuating load, lower bearing can be by two to three sets of various different bearing types of bearing components, ensure the smooth operation of unit and longer life.
6 cable inlet seal
Cable with rubber sleeve and gland seal compression between the motor, and the motor cover to prevent the media from the cable interface into the motor cavity.
7 cooling water jacket
22 kW motor external set a cooling water jacket, with the conveying pump water to the motor for cooling, ensure electric pump at the lowest water level, still can normal operation.
8 pump safety protection
1) the motor stator winding is equipped with PT100 temperature sensor, the motor winding temperature monitoring, through the external special control device to protect the motor overheating.
2) oil indoor setting leakage sensor. When water enters the oil chamber to a certain degree, the sensor sends out the signal, and the external special control device is used for protecting the electric pump.
9 material
For the corrosive medium or strong corrosive containing solid particles of the medium, the abrasion resistance of high chromium cast iron, stainless steel and other materials.
Installation method

WQ(WQB) series submersible sewage pump
Mobile wet installation

Pump and hose or pipe connection, directly into the water, no fixed, convenient transfer to different sites.

WQ(WQB) series submersible sewage pump
Automatic coupling fixed wet type installation

The pump is connected with the drainage pipe automatically by the coupling device. Pump along the guide rod into the water and drainage pipeline automatic connection, when the pump is automatically loose, easy to install and remove.

WQ(WQB) series submersible sewage pump
Vertical fixed dry type installation

Pump vertical installed in the pool side of the clean pump pit, the staff can enter the pump pit for rapid repair of the pump. Even if the pump pit is submerged, the pump can still operate normally.

WQ(WQB) series submersible sewage pump
Horizontal fixed dry type installation

Pump horizontal installed in the pool side of the clean pump pit, the staff can enter the pump pit for rapid repair of the pump. Even if the pump pit is submerged, the pump can still operate normally.
