First, the product overview WQ submersible sewage pump main components from the impeller, pump body, base submersible motor. Pump and motor are the same shaft, because the pump is located at the bottom of the entire sewage pump, it can maximize the suction area of ​​the remaining sewage. Impeller for the double flow channel design, greatly improved the ability of dirt flow, can effectively pass the diameter of the pump diameter of 50% of the solid particles. Product implementation Q / TBJW2-2003 "sewage sludge submersible pump" standard. WQ series submersible sewage pump Second, the product features 1, the cable is durable, waterproof: heavy-duty soft rubber cables, resin infusion, compression fixed, no pull, long-term reliability. 2, double seal, double protection: double machine seal series configuration, the real double protection to ensure motor safety. 3, multi-channel detection, multi-channel protection: oil-water probe, float switch, can be real-time detection and alarm, shutdown, fault signal retention and other functions to make submersible motor safe and reliable. 4, over-current ability: dual-channel design, to ensure high pump efficiency and non-blocking. 5, easy maintenance: the use of dual-rail coupling device, so that when the pump take off and landing without underwater operation, easy maintenance, saving time and labor. Third, the working conditions Flow range: 2 ~ 1500m3 / h Head range: 3 ~ 45m Speed ​​n: 970 ~ 2900r / min Ambient temperature T: ≤ +40 ℃ Medium temperature: -15 ℃ ~ +60 ℃ Medium density: ≤ 1.3X103kg / m3 Medium PH value range: 5 ~ 9 System maximum working pressure: ≤ 0.6Mpa
