1.The impeller of the WQ(D) submersible sewage pump adopts a closed double channel design, which increases the service life of the product due to symmetrical flow channels, good balance, smooth operation, and low vibration. The flow passage has strong passing capacity, and the measured efficiency is higher than the national standard, which saves energy and
reduces consumption.
2.The designed submersible motor has lP68 protection level and F insulation class, with good diving cooling effect, low temperature rise, and long insulation life. Over-current protectors are installed below 7.5kW to ensure that the motor can automatically cut off power in case of abnormal situations.
3.lt adopts a double end mechanical seal, with an external skeleton oil seal below 7.5kW, and a two to three series mechanical seals for motor shaft seals above 11kW, forming multiple reliable sealing lines. One is in the medium inside the pump, effectively preventing water from entering the oil chamber, and the other is in the oil chamber to prevent oil from entering the motor chamber. The oil chamber is filled with suitable mechanical oil, while lubricating and cooling the friction surfaces of the two independent machine seals, making the machine seal work more reliable.in addition, it can also takeaway the heat generated by the lower bearings and some heat generated by the motor.. Some water pumps have special cable manufacturing processes that can completely prevent water from entering the motor through the small gaps between the wires when the cable skin is damaged or the front end of the cable is submerged in water.
