GNWQ series sewage cutting pump non-clogging submersible sewage water pump is suitable for 0-20 meters, large flow, medium and low head use, full head, low energy consumption. The product also adopts an easy-to-remove cutter head design, which can be replaced with different forms of cutter heads according to different use environments, including municipal and livestock farms. A large number of practical applications and laboratory tests have proved that the GNWQ submersible cutter sewage pump is superior to any current domestic sewage pump in terms of college and anti-clogging performance, achieving a perfect combination of high efficiency + non-clogging characteristics.
The submersible sewage slurry cutter pump used in the ESP device is a multi-stage centrifugal pump, which operates in a vertical position. Although their structure and operating characteristics have been developing for many years, their basic operating principles remain unchanged.
The generated liquid loses kinetic energy in the diffuser after receiving the huge centrifugal force generated by the high speed of the impeller, and converts kinetic energy into pressure energy in the diffuser.
The pump shaft is connected with the protector through the mechanical coupling at the bottom of the submersible cutter slurry sewage pump. The well fluid enters the pump through the inlet filter screen and is lifted by the pump stage.
Other components include radial bearings (shaft sleeves) distributed along the length of the shaft to provide radial support for the high-speed rotating pump shaft.
The optional thrust bearing bears part of the axial force generated in the submersible sewage water pump, but most of the force is absorbed by the thrust bearing of the protector.
1. Vortex impeller with non-clogging design;
2. Material of impeller and knife ring: high chromium stainless steel 420, hardness HRC49-52, good wear resistance;
3. Heavy duty bearing and SS420 shaft;
4. Double mechanical seal consists of two seals in series. The super wear-resistant mechanical seal made of silicon carbide ensures the best sealing effect.
