1、 Wqk / QG submersible sewage pump with cutting device

Wqk / QG sewage pump with cutting device has very strong sewage passing capacity and good cutting performance. It can cut and discharge long fiber, plastic, paper, belt, cloth strip, straw, rope and other impurities in the sewage, and adopts the most advanced method to design the most reasonable hydraulic characteristics, so that the electric pump can operate at full head, and the best combination of excellent dry-type motor and water pump, The total efficiency of the electric pump is the same as that of the ass belt cutting device of ABS company of West Germany. The electric pump adopts high-quality cemented carbide. The surface of double face mechanical seal and framework oil seal shall not exceed 1 / 2 of the motor height, and the temperature of pumping dirt shall not exceed 40 ℃.

WQX series sewage submersible sewage pump is mainly used to discharge domestic wastewater, sewage, human manure and urine, solid suspended solids and non corrosive media containing short fiber paper chips, sawdust, starch, sediment, ore particles, etc. the temperature of the pumped liquid is not more than 40 ℃, the density is not more than 1200kg / m3, and the pH value is ~ 9. The pump adopts double face mechanical seal and rotating impeller. The impeller is made of stainless steel, wear-resistant, non clogging, non winding, small volume, compact structure and convenient carrying.

2、 Maintenance of wqk / QG submersible sewage pump with cutting device:

1. The electric pump shall be managed and used by special personnel, and the insulation resistance between the pump winding and the shell shall be checked regularly, and the minimum value shall not be less than 0.5 megohm. Otherwise, the stator must be removed and dried, and the insulation resistance can be used only after the insulation resistance is increased.

2. After each use, especially for thicker and sticky slurry, it should be put in clean water for several minutes before storage.

3. After every 300 ~ 500 hours of use, the oil hole screw at the waist should be opened and supplemented with pure No. 10 engine oil, and the mechanical seal should be used to maintain good lubrication. If a large amount of water is found in the oil chamber, it indicates that the mechanical seal is invalid and should be replaced.

4. After starting the electric pump, if the flow is insufficient or the lift cannot reach the specified value (except for the large resistance or blockage of the pipeline), it may be that the direction of the pump is reversed. At this time, the power supply should be disconnected and any two of the three phase lines of the cable should be replaced with each other, and then the pump can be started after the measurement is connected.

5. After disassembly and maintenance of the electric pump, the sealing performance must be checked by 0.2MPa air tightness test.

6. The elbow and the electric pump are separated and placed in the board box. Please install the elbow on the electric pump. If the electric fruit is connected with the pipeline, it is unnecessary to install the elbow.
