5, drain leakage is one of the most dangerous factors submersible pump pumps the most common faults 150WQ150-40-30 also endanger personal safety. Symptom when closing the knife, for the distribution transformer room leakage protection has tripped (if no leakage protection will be very dangerous, can cause the motor to burn out). This is mainly due to the body of water submersible pump, submersible pump causing the motor winding insulation resistance is reduced, resulting in protection action. At this point with the shake table or multimeter R × 10kΩ block, measuring motor windings of the shell has some leakage resistance. Long-term use of submersible pumps, causing severe mechanical seal face wear, thus penetrate water, soak the motor windings form the drain. You can remove the submersible pump motors placed in the drying room, drying or 100-200W incandescent bulbs; measure the insulation resistance is infinite, then the mechanical seal new ones, then the pump can be installed and put into use. 150WQ200-20-30 pump submersible sewage pumps, non-clog sewage pumps 150WQ140-41-30 pumps, submersible pumps without clogging a, WQ series submersible sewage pump Product Overview JB / T 51JS "submersible sewage pump" product standards for sewage submersible pumps using the conditions specified below. ① mainly used for transporting solid particles containing short fibers, such as sewage and dirt. When the pump impeller with a cutting edge, can also be used for transporting sewage containing long fibers. ② transport medium temperature should not exceed 40 ℃. ③ pH of the transmission medium is usually 4 to 10. ④ volume solids content of the transmission medium is generally not more than 2% over the medium density less than 1200kg / m3. ⑤ submersible sewage pump submerged deeper than 5m. ⑥ submersible sewage pump is completely submerged in water should be able to run continuously lift within the prescribed range.
