Automatic level control system can automatically control the start and stop of the pump, without special care, reduce management costs. 7. automatic dual-rail mounting system, it gives the installation, maintenance has brought great convenience, this may not have access to the sump. 8. The product leakage, leakage, phase, overload and so on down to start automatically prosecuted, improve product safety and reliability. QW-type sewage submersible pumps Overview for: 1. enterprises wastewater discharge. 2. Urban sewage treatment plant discharge system. 3. subway, basement, air defense systems drainage stations. 4. hospitals, hotels, high-rise building sewage discharges. 5. residential sewage pumping station. 6. municipal engineering and construction project emissions dilute slurry. 7. waterworks water supply installations. 8. sewage farms and rural irrigation. 9. Water treatment equipment for mining and exploration. Conditions of use water temperature 60 degrees Celsius, the liquid PH value of 4-10. 10. The place of human hands are worried, suction river mud. Submersible submersible pumps are often encountered in the use of oil spills, leakage, trip, head reach, impeller does not turn, low flow, low speed problem, the following questions for these common faults detailed analysis: 1, impeller speed low , head reach Many customers bought to start using a submersible pump, found that the actual lift lift not up to standard, measured and found to have a low speed. This may be wired incorrectly suggested a change in the line of fire. There may be a submersible pump is poor, head reach. 2, submersible water pumps, weakness, remove the submersible pump flow is small, flexible rotor inspection 65WQ30-35-7.5 water, electricity rotor can turn. Dismantle pump inspection found 65WQ35-50-11 pumps, submersible pumps loose between the lower end of the shaft and bearing, and the rotor down, so the rotor weakness, output power is small. Using appropriate gasket between the rotor and the bearing pad, so the rotor moves, installation commissioning, fault can be ruled out. 3, the power, do not turn the impeller submersible pump after power has buzzing hum, do not turn the impeller. Cut off the power 80WQ35-10-3 pump impeller intake struck at, if not move aside, indicating that the rotor is stuck. Submersible pumps can be disassembled to check whether the lower rotor bearing ball crushing lead stuck rotor; if toggle wheel, but not after power transfer pump impeller, the probable cause is a serious bearing wear, when power generated in the stator magnetic rotor suck live and can not rotate. Replace the bearings reassembled pumps, flexible impeller struck troubleshooting.
