WQ series submersible sewage pump is suitable for the discharge of serious polluting wastewater of factories and factories, sewage discharge stations in residential areas, drainage systems of urban sewage treatment plants, drainage stations of civil air defense systems, etc., Material, can also be used for clean water and with corrosive media. So in use, it has what to use it? And what should pay attention to? With these questions, then introduce you to WQ series submersible sewage pump usage and precautions. WQ series submersible sewage pump usage and precautions 1.QW submersible sewage pump before use should be carefully checked for damage to the cable, the fastener is loose or off, the pump during transport, storage, installation without distortion Or damaged. 2. Use 500V megger to measure the same and relative insulation resistance of the electric pump motor. The value should not be less than 2 megohms. Otherwise, the stator windings of the motor should be dried. The drying temperature should not exceed 120 ℃. 3. The series of pumps installed fixed and mobile two. When using a fixed automatic installation, the chain should be respectively (into the pump outlet from the parallel, the connection should be parallel to the pump outlet) two rings screw or lifting board lifting pump up and down. Slide slowly and evenly along the guide rail until it is automatically coupled in place. When using the mobile installation, the first set of flexible hose, with the rope into the two rings up and down lifting pump, be careful not to use the cable as a rope to avoid danger. 4.QW Submersible sewage pump connected to the rotation direction from the inlet as a counterclockwise rotation, if the pump reversal, simply cable any two lines in the alignment of the wiring position can be. 5. Electric pump chassis ground must be strictly in accordance with the relevant procedures, in order to ensure the safety of personal use, in the pump operation, the installation is prohibited in the vicinity of people into the water do ~ or move, in case the pump leakage An accident occurred. 6. Electric pump in the absence of special circumstances must be equipped with automatic pump control cabinet, do not directly linked to the grid or use the knife switch to connect the power to ensure the normal operation of the pump. 7. Do not operate the electric pump for a long time in the low-lift state (generally, the lift should not be less than 60% of the rated lift). It is better to control the pump within the recommended lift range to prevent the electric pump from burning out due to overload. 8. Self-circulation cooling device is strictly prohibited the long-term operation of the pump exposed surface to prevent damage to the pump overheating.
