QWP non-clogging stainless steel submersible sewage pump use precautions

QWP non-clogging stainless steel submersible sewage pump Caution:
1. Pump should be carefully checked before using the cable has been damaged, the fasteners are loose or fall off, the pump in the transport, storage, installation process without any deformation or damage.
2. Use 500V megger to measure the insulation resistance between the same and relative ground of the pump motor. The value should not be less than 2 megohms. Otherwise, the motor stator windings should be dried. The drying temperature should not exceed 120 ℃.
3. The series of pumps are installed fixed and mobile two. When using a fixed automatic installation, the cables should be threaded into the two lifting rings (the pump outlet, the connection should be parallel to the pump outlet) lifting rings or hoisting plate. Slow down evenly along the rail until it is automatically coupled into place. When using the mobile installation, the first set of the hose, with chain cable into the two lifting rings up and down the pump, be careful not to use the cable as a rope, so as to avoid danger.
4. The direction of rotation of the pump after turning on from the inlet as a counter-clockwise rotation, if the pump reversal, simply wire any two lines in the wiring position can be adjusted.
5. Pump chassis grounding must be strictly in accordance with the relevant procedures to be properly, in order to ensure personal safety, in the pump is running, is strictly prohibited in the vicinity of the installation, people do things or mobile water, just in case of pump leakage occurred Accident.
6. Pump in no special circumstances must be equipped with automatic pump control cabinet, not directly linked to the grid or use the knife switch to power, to ensure the normal operation of the pump.
7. The electric pump should not be operated in a low head state for a long time. (Generally, the head should not be less than 60% of the rated head). It is best to control the pump within the recommended range of lift to prevent the motor from burning.
8. No self-circulation cooling device pump is strictly prohibited the overall long-term exposure to surface water to prevent damage to the pump overheating.
9. If the pump is used to suck thicker than the viscosity of the slurry, the need to clean the pump chamber to prevent the pump to leave sediment.
