4, submersible pump oil spill oil spill was mainly due to severe wear sealed box, causing the oil chamber sealed box or outlet box office seal leakage caused by poor. When the oil chamber leak sealed box, visible traces of oil in the water festival place. There is a section at the water filling hole, unscrew the screws, observe the oil chamber is water. If the oil chamber inlet, it is bad seal, replace sealed box 150WQ70-40-18.5, to prevent serious water oil chamber, penetrate the motor. If there is oil submersible pump cable roots phenomenon, fall within the motor oil spills. Generally bad seal or seal stopper motor rewinding after failure caused by the use of lead; some are caused by broken water pump wiring board. After checking to determine, for qualified new can. And measuring the degree of motor insulation 150WQ100-40-22, if the insulation is not good to be in time, while the oil in the motor replaced. , Submersible sewage pump seal oil chamber with high precision interference leakage detection sensors, and stator windings of the thermal components embedded, absolute protection of pump motor. 5, submersible sewage pumps can be equipped according to user needs automatic security control cabinet, the pump leakage, leakage, overload and overtemperature protection absolute WQ, improved product safety and reliability. 6, at the beginning of submersible sewage pumps can float according to the required level changes, automatic control of pump start and stop, without special care, extremely easy to use. 7, submersible sewage pump according to user needs with double rail automatic coupling installation system 150WQ150-22-18., To installation, maintenance bring great convenience, may not have to get into the sump. 8, submersible sewage pumps can lift the whole range, and to ensure that the motor is not overloaded. 9, submersible sewage pumps, there are two types of installation, fixed automatic coupling installation system and traveling free installation system. 150WQ200-13.5-1, WQ, submersible sewage pump provided by Anguo Shi Yuan Pumps Limited.
