The WQK belt cutting device sewage pump adopts high-quality carbide, a dynamic seal structure combining double-end mechanical seals and skeleton oil seals. For the normal operation of the electric pump and the safety of workers, users should equip the electric motor with a leakage protector. , when working for a long time, the motor of this pump is allowed to expose the liquid surface, which shall not exceed 1/2 of the height of the motor, and the temperature of the pumped dirt shall not exceed 40°C. WQK belt cutting device sewage pump has a particularly strong sewage passing capacity and good belt cutting performance. It can chop long fibers, plastics, paper, belts, cloth strips, straw, rope and other impurities in the sewage and discharge them.

The WQK belt cutting device sewage pump Precautions for use
(1) Before using the electric pump, you must first check whether the cable is damaged. When transporting and installing the water pump, cutting iron may pull or damage the cable to avoid accidents caused by water leakage after the cable ruptures. If the cable is hard to crack, the cable should be replaced immediately. And use a megohmmeter to check whether the insulation resistance of the electric pump is normal (the insulation resistance must not be less than 1 megohm)
(2) Recognize the grounding wire (the grounding wire is usually yellow or green or connected with a grounding mark), and connect the grounding wire according to the prescribed procedures. (Our factory's ground wire is equipped with a ground mark).
(3) Choose a suitable protector (such as leakage protector, air switch, phase failure overcurrent protector, etc.) and do not connect directly with a knife switch.
(4) Connect the power cord according to the standard, test the power supply, check whether the electric pump is operating normally, and determine whether the steering is correct. If the steering is incorrect, just swap any two of the three power cords (pay attention to the operation) The time cannot exceed half a minute).
(5) Install the water outlet joint and water outlet hose (or iron pipe), tie a rope on the handle of the electric pump (cables must not be used to replace the hanging rope), put the electric pump into the liquid book to be pumped, and turn on the power supply and is ready to use.
(6) In order to ensure personal safety, when the electric pump is connected to power, it is strictly prohibited to install and launch water operations near the electric pump (such as moving or inspecting, troubleshooting, etc.) and touching the electric pump to prevent accidents caused by electric pump leakage!
(7) It is strictly prohibited for the entire electric pump to be exposed to the water for long-term operation (or short-term operation). The "start" and "stop" of the electric pump should not be too frequent to prevent overheating and damage to the motor.
(8) Long-term pumping of liquids with high sand content will cause greater wear and tear on the flow-passing parts of the WQK sewage pump with cutting device. It is recommended to use our cyclonic sewage submersible electric pump product.
(9) If it is found that the WQK sewage pump with cutting device does not rotate, the protector trips, the fuse blows out and other abnormal phenomena when it is running, the power supply should be cut off immediately and check whether there is any problem with the power protector wiring etc.
If these external devices are normal, the electric pump may be faulty and should not be used at this time to avoid an accident!

The WQK belt cutting device sewage pump Maintenance and maintenance of Precautions
1. After each use, especially for thicker and more viscous slurries, it should be placed in clean water for a few minutes before storage.
2. After every 300 to 500 hours of use of the electric pump, the waist oil hole screw should be opened and replenished with pure No. 10 engine oil, and a 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 has failed and should be replaced.
3. The electric pump should be managed and used by dedicated personnel, and the insulation resistance between the electric pump winding and the casing should be regularly checked to see if it is normal and must not be less than 0.5 megohms. Otherwise, the stator must be removed and dried, and the insulation resistance can be used only after the insulation resistance rises.
4. After the electric pump is started, if it is found that the flow is insufficient or the lift is less than the specified value (unless the pipeline resistance is large or blocked), the direction may be reversed. At this time, the power supply should be disconnected and any two of the three phase wires of the cable should be swapped with each other. Finally, connect the new meter and start again.
5. After the electric pump is disassembled and repaired, the sealing performance must be checked by a 0.2MPa air tightness test.
6. If the elbow and electric pump are placed separately in the crate, please install the elbow on the electric pump. If the electric pump is connected to the pipeline, there is no need to install the elbow.
